(07/14/2014) The world’s grasslands are being destabilized by fertilization, according to a paper recently published in the journal Nature. In a study of 41 grassland communities on five continents, researchers found that the presence of fertilizer weakened grassland species diversity.
Only 15 percent of world's biodiversity hotspots left intact
(07/14/2014) The world's 35 biodiversity hotspots—which harbor 75 percent of the planet's endangered land vertebrates—are in more trouble than expected, according to a sobering new analysis of remaining primary vegetation. In all less than 15 percent of natural intact vegetation is left in the these hotspots, which include well-known jewels such as Madagascar, the tropical Andes, and Sundaland.
Booming populations, rising economies, threatened biodiversity: the tropics will never be the same
(07/07/2014) For those living either north or south of the tropics, images of this green ring around the Earth's equator often include verdant rainforests, exotic animals, and unchanging weather; but they may also be of entrenched poverty, unstable governments, and appalling environmental destruction. A massive new report, The State of the Tropics, however, finds that the truth is far more complicated.
Unrelenting population growth driving global warming, mass extinction
(06/26/2014) It took humans around 200,000 years to reach a global population of one billion. But, in two hundred years we've septupled that. In fact, over the last 40 years we've added an extra billion approximately every dozen years. And the United Nations predicts we'll add another four billion—for a total of 11 billion—by century's end.
Broken promises no more? Signs Sabah may finally uphold commitment on wildlife corridors
(06/23/2014) Five years ago an unlikely meeting was held in the Malaysian state of Sabah to discuss how to save wildlife amid worsening forest fragmentation. Although the meeting brought together longtime adversaries—conservationists and the palm oil industry—it appeared at the time to build new relationships and even point toward a way forward for Sabah's embattled forests.
After throwing out referendum, Ecuador approves oil drilling in Yasuni's embattled heart
(06/02/2014) By 2016, oil drilling will begin in what scientists believe is the most biodiverse place on the planet: remote Yasuni National Park. Late last month, Ecuador announced it had approved permits for oil drilling in Yasuni's Ishpingo-Tambococha-Tiputinin (ITT) block, an untouched swathe of primary rainforest covering around 100,000 hectares or about 10 percent of the park.
Of jaguars and loggers: new film to showcase one of the least-known regions in the deep Amazon
(06/02/2014) In August, three young filmmakers will go on the expedition of a lifetime. They plan to spend six months filming in one of the most remote, most spectacular, and most endangered ecosystems on the planet: the Las Piedras River system. This unprotected swathe of Amazon jungle contains massive anacondas, prowling jaguars, and even uncontacted indigenous people.
Extinction rates are 1,000x the background rate, but it's not all gloomy
(05/29/2014) Current extinction rates are at the high end of past predictions, according to a new paper published today in Science, however conservation efforts combined with new technologies could make a big difference. New research led by Stuart Pimm of Duke University argues that humans have pushed the current extinction rate to 1,000 times the historical rate.
Giant ibis, little dodo, and the kakapo: meet the 100 weirdest and most endangered birds
(04/10/2014) The comic dodo, the stately great auk, the passenger pigeon blotting out the skies: human kind has wiped out nearly 200 species of birds in the last five hundred years. Now, if we don't act soon we'll add many new ones to the list: birds such as the giant ibis, the plains-wanderer, and the crow honeyeater. And these are just a few of the species that appear today on the long-awaited EDGE list.
Next big idea in forest conservation? Connecting deforestation to disease
(04/03/2014) Thomas Gillespie is concerned with the connections between conservation and disease, with a particular emphasis on primates. Much of his research examines the places where humans and animals are at a high risk of exchanging pathogens, and how human-caused disturbances, such as deforestation, can change disease dynamics and impacts.
Apocalypse now? Climate change already damaging agriculture, acidifying seas, and worsening extreme weather
(03/31/2014) It's not just melting glaciers and bizarrely-early Springs anymore; climate change is impacting every facet of human civilization from our ability to grow enough crops to our ability to get along with each other, according to a new 2,300-page report from the Intergovernmental Panel on Climate Change (IPCC). The massive report states definitively that climate change is already affecting human societies on every continent.
Mother of God: meet the 26 year old Indiana Jones of the Amazon, Paul Rosolie
(03/17/2014) Not yet 30, Paul Rosolie has already lived a life that most would only dare dream of—or have nightmares over, depending on one's constitution. With the Western Amazon as his panorama, Rosolie has faced off jaguars, wrestled anacondas, explored a floating forest, mentored with indigenous people, been stricken by tropical disease, traveled with poachers, and hand-reared a baby anteater. It's no wonder that at the ripe age of 26, Rosolie was already written a memoir: Mother of God.
Lost Animals: Extinction and the Photographic Record – book review
(03/04/2014) Lost Animals: Extinction and the Photographic Record reaches into your imagination and draws you closer to the final days of a variety of extinct animals on Earth. Lost Animals: Extinction and the Photographic Record is filled with poignant and powerful first-hand accounts, photographic records, and illustrations.
Amazon trees super-diverse in chemicals
(03/03/2014) In the Western Amazon—arguably the world's most biodiverse region—scientists have found that not only is the forest super-rich in species, but also in chemicals. Climbing into the canopy of thousands of trees across 19 different forests in the region—from the lowland Amazon to high Andean cloud forests—the researchers sampled chemical signatures from canopy leaves and were surprised by the levels of diversity uncovered.
The lemur end-game: scientists propose ambitious plan to save the world's most imperiled mammal family
(02/20/2014) Due to the wonderful idiosyncrasies of evolution, there is one country on Earth that houses 20 percent of the world's primates. More astounding still, every single one of these primates—an entire distinct family in fact—are found no-where else. The country is, of course, Madagascar and the primates in question are, of course, lemurs. But the far-flung island of Madagascar, once a safe haven for wild evolutionary experiments, has become an ecological nightmare. Overpopulation, deep poverty, political instability, slash-and-burn agriculture, illegal logging for lucrative woods, and a booming bushmeat trade has placed 94 percent of the world's lemurs under threat of extinction, making this the most imperiled mammal group on the planet. But, in order to stem a rapid march toward extinction, conservationists today publicized an emergency three year plan to safeguard 30 important lemur forests in the journal Science.
High-living frogs hurt by remote oil roads in the Amazon
(01/14/2014) Often touted as low-impact, remote oil roads in the Amazon are, in fact, having a large impact on frogs living in flowers in the upper canopy, according to a new paper published in PLOS ONE. In Ecuador's Yasuni National Park, massive bromeliads grow on tall tropical trees high in the canopy and may contain up to four liters of standing water. Lounging inside this micro-pools, researchers find a wide diversity of life, including various species of frogs. However, despite these frogs living as high as 50 meters above the forest floor, a new study finds that proximity to oil roads actually decreases the populations of high-living frogs.
Over 75 percent of large predators declining
(01/09/2014) The world's top carnivores are in big trouble: this is the take-away message from a new review paper published today in Science. Looking at 31 large-bodied carnivore species (i.e those over 15 kilograms or 33 pounds), the researchers found that 77 percent are in decline and more than half have seen their historical ranges decline by over 50 percent. In fact, the major study comes just days after new research found that the genetically-unique West African lion is down to just 250 breeding adults.
Featured video: what would a world without wildlife look like?
(12/20/2013) Greenpeace today released a clever video highlighting the global biodiversity crisis with a little help from a much-beloved Disney film. While it might seem unlikely the Africa's animals will vanish, this is exactly what's happening in parts of the continent due to poaching, unsustainable bushmeat trade, habitat loss, massive development projects that are often poorly planned, and a booming human population.
Top 10 HAPPY environmental stories of 2013
(12/19/2013) China begins to tackle pollution, carbon emissions: As China's environmental crisis worsens, the government has begun to unveil a series of new initiatives to curb record pollution and cut greenhouse emissions. The world's largest consumer of coal, China's growth in emissions is finally slowing and some experts believe the nation's emissions could peak within the decade. If China's emissions begin to fall, so too could the world's.
Using stories to connect people to biodiversity: an interview with Tara Waters Lumpkin, PhD
(12/18/2013) In a world where extinctions are almost commonplace and global warming barely raises an eyebrow, very few of us can return to find the places we grew up in unsullied by development. Sometimes, all that is left of a favorite grove of trees or strip of forest are memories. Through Izilwane: Voices for Biodiversity Project, an online magazine for story-tellers, Tara Waters Lumpkin has succeeded in bringing together more than one hundred "eco-writers" who have shared their memories, highlighted environmental crises in their localities and raised their voices against habitat destruction.
Scientists: well-managed forest restoration benefits both biodiversity and people
(12/16/2013) In November this year, the world was greeted by the dismaying news that deforestation of the Brazilian Amazon jumped 28% in the past year. The year 2013 also holds the dubious distinction of being the first time since humans appeared on the planet, that carbon concentrations in the atmosphere rose to 400 parts per million. A map by Google revealed that Russia, Brazil, the United States, Canada and Indonesia all displayed over 10 million hectares of gross forest loss from 2000-2012, with the highest deforestation rate occurring in Malaysia.
Big data shows tropical mammals on the decline
(12/12/2013) The world's largest remote camera trap initiative—monitoring 275 species in 17 protected areas—is getting some big data assistance from Hewlett-Packard (HP). To date, the monitoring program known as the Tropical Ecology Assessment and Monitoring (TEAM) Network has taken over 1.5 million photos of animals in 14 tropical countries, but conservationists have struggled with how to quickly evaluate the flood of data.
Sky islands: exploring East Africa's last frontier
(12/04/2013) The montane rainforests of East Africa are little-known to the global public. The Amazon and Congo loom much larger in our minds, while the savannas of East Africa remain the iconic ecosystems for the region. However these ancient, biodiverse forests—sitting on the tops of mountains rising from the African savanna—are home to some remarkable species, many found only in a single forest. A team of international scientists—Michele Menegon, Fabio Pupin, and Simon Loader—have made it their mission to document the little-known reptiles and amphibians in these so-called sky islands, many of which are highly imperiled.
86 percent of big animals in the Sahara Desert are extinct or endangered
(12/03/2013) Bigger than all of Brazil, among the harshest ecosystems on Earth, and largely undeveloped, one would expect that the Sahara desert would be a haven for desert wildlife. One would anticipate that big African animals—which are facing poaching and habitat loss in other parts of the world—would thrive in this vast wilderness. But a new landmark study in Diversity and Distributions finds that the megafauna of the Sahara desert are on the verge of total collapse.
Animal Earth: exploring the hidden biodiversity of our planet
(12/03/2013) Most of the species on Earth we never see. In fact, we have no idea what they look like, much less how spectacular they are. In general, people can identify relatively few of their backyard species, much less those of other continents. This disconnect likely leads to an inability in the general public to relate to biodiversity and, by extension, the loss of it. One of the most remarkable books I have read is a recent release that makes serious strides to repair that disconnect and affirm the human bond with biodiversity. Animal Earth: The Amazing Diversity of Living Creatures written by Ross Piper, a zoologist with the University of Leeds, opens up the door to discovery.
Over 350 species added to the IUCN Red List's threatened categories in the last six months
(11/26/2013) The number of threatened species on the IUCN Red List has grown by 352 since this summer, according to an update released today. Currently, 21,286 species are now listed as threatened with extinction out of the 71,576 that have been evaluated. The new update comes with both good and bad news for a number of high-profile imperiled species, but only covers about 4 percent of the world's described species.
Microhabitats could buffer some rainforest animals against climate change
(11/25/2013) As temperatures increase worldwide due to anthropogenic climate change, scientists are scrambling to figure out if species will be able to survive rapidly warming ecosystems. A new study in Global Change Biology offers a little hope. Studying reptiles and amphibians in the Philippines, scientists say some of these species may be able to seek refuge in cooler microhabitats, such as tree holes or under the soil, in order to stay alive during intensifying heatwaves. But, the scientists' stress, the shelter from microhabitats can only protect so far.
Scientists identify 137 protected areas most important for preserving biodiversity
(11/14/2013) Want to save the world's biodiversity from mass extinction? Then make certain to safeguard the 74 sites identified today in a new study in Science. Evaluating 173,000 terrestrial protected areas, scientists pulled out the most important ones for global biodiversity based on the number of threatened mammals, birds, and amphibians found in the parks. In all they identified 137 protected areas (spread over 74 sites as many protected areas were in the same region) in 34 countries as 'irreplaceable.'
Could camera trap videos galvanize the world to protect Yasuni from oil drilling?
(11/07/2013) Even ten years ago it would have been impossible to imagine: clear-as-day footage of a jaguar plodding through the impenetrable Amazon, or a bicolored-spined porcupine balancing on a branch, or a troop of spider monkeys feeding at a clay lick, or a band of little coatis racing one-by-one from the dense foliage. These are things that even researchers who have spent a lifetime in the Amazon may never see. Now anyone can: scientists at the Tiputini Biodiversity Station in Ecuador's Yasuní National Park have recently begun using camera trap videos to take movies of animals few will ever view in their lifetimes. The videos—following years of photo camera trapping—provide an intimate view of a world increasingly threatened by the oil industry.
Governments should respond to ocean acidification 'as urgently as they do to national security threats'
(10/03/2013) The oceans are more acidic now than they have been for at least 300m years, due to carbon dioxide emissions from burning fossil fuels, and a mass extinction of key species may already be almost inevitable as a result, leading marine scientists warned on Thursday. An international audit of the health of the oceans has found that overfishing and pollution are also contributing to the crisis, in a deadly combination of destructive forces that are imperiling marine life, on which billions of people depend for their nutrition and livelihood.
Over 100 scientists warn Ecuadorian Congress against oil development in Yasuni
(10/03/2013) Over 100 scientists have issued a statement to the Ecuadorian Congress warning that proposed oil development and accompanying roads in Yasuni National Park will degrade its "extraordinary biodiversity." The statement by a group dubbed the Scientists Concerned for Yasuni outlines in detail how the park is not only likely the most biodiverse ecosystems in the western hemisphere, but in the entire world. Despite this, the Ecuadorian government has recently given the go-ahead to plans to drill for oil in Yasuni's Ishpingo-Tambococha-Tiputini (ITT) blocs, one of most remote areas in the Amazon rainforest.
Forgotten species: the nearly extinct primate that can be shot on sight
(09/27/2013) The attention paid to charismatic popular primates—such as gorillas, chimps, orangutans, lion tamarins, and even some lemurs—could make one suppose that conservationists have the protection of our closest relatives well in hand; the astounding fact that no primate species is known to have gone extinct in the last hundred years (despite large-scale destruction of their habitats) seems to confirm this statement. However, looking more closely at the data, one finds that not only are many of the world's primates slipping toward extinction, but a number of them have received little conservation attention. According to the IUCN Red List, a staggering 48 percent of the world's primates are threatened with extinction: that's a worse percentage than amphibians which have been ravaged by a global epidemic. And although a handful of the world's 600-plus primates have garnered conservation adoration, many remain obscure.
'Ecological Armageddon': mammals vanish entirely from forest fragments after 25 years
(09/26/2013) As tropical forests worldwide are increasingly cut into smaller and smaller fragments, mammal extinctions may not be far behind, according to a new study in Science. Tracking native smalls mammals in Chiew Larn Reservoir, Thailand for over 25 years, scientists found a stunning and rapid decline in mammal populations, until most forests were almost completely emptied of native mammals.
Climate change could kill off Andean cloud forests, home to thousands of species found nowhere else
(09/18/2013) One of the richest ecosystems on the planet may not survive a hotter climate without human help, according to a sobering new paper in the open source journal PLoS ONE. Although little-studied compared to lowland rainforests, the cloud forests of the Andes are known to harbor explosions of life, including thousands of species found nowhere else. Many of these species—from airy ferns to beautiful orchids to tiny frogs—thrive in small ranges that are temperature-dependent. But what happens when the climate heats up?
Scientists outline how to save nearly 70 percent of the world's plant species
(09/05/2013) In 2010 the Convention on Biological Diversity (CBD) pledged to set aside 17 percent of the world's land as protected areas in addition to protecting 60 percent of the world's plant species—through the Global Strategy for Plant Conservation (GSPC)—by 2020. Now a new study in Science finds that the world can achieve both ambitious goals at the same time—if only we protect the right places. Looking at data on over 100,000 flower plants, scientists determined that protecting 17 percent of the world's land (focusing on priority plant areas) would conserve 67 percent of the world's plants.
Ground zero for endangered species: new program to assist animals on the brink across Southeast Asia
(08/27/2013) Organizations within the international conservation community are joining forces to minimize impending extinctions in Southeast Asia, where habitat loss, trade and hunting have contributed to a dramatic decline in wildlife. The coalition is aptly named ASAP, or the Asian Species Action Partnership.
Pesticide problems in the Amazon
(08/21/2013) As the world’s population increases and agricultural frontiers expand into native tropical habitats, researchers are working furiously to understand the impacts on tropical forests and global biodiversity. But one obvious impact has been little studied in these agricultural frontiers: pesticides. However a new study in the journal Philosophical Transactions of The Royal Society B seeks to shine a light on the problem.
Zoo races to save extreme butterfly from extinction
(08/15/2013) In a large room that used to house aquatic mammals at the Minnesota Zoo, Erik Runquist holds up a vial and says, 'Here are its eggs.' I peer inside and see small specks, pale with a dot of brown at the top; they look like a single grain of cous cous or quinoa. Runquist explains that the brown on the top is the head cap of the larva, a fact that becomes more clear under a microscope when you can see the encased larva squirm. I'm looking at the eggs of a Poweshiek skipperling, a species that is more imperiled than pandas, tigers, or bluewhales. Once superabundant, only several hundred Poweshiek skipperlings may survive on Earth today and the eggs I'm looking at are the only ones in captivity.
Forest fragmentation leading to higher extinction rates
(08/13/2013) The world's species are in worse trouble than widely-assumed, according to a new paper in the Proceedings of the National Academy of Sciences (PNAS), which reevaluates how scientists estimate extinction rates. The new model takes into account the impact of forest fragmentation on extinction rates for the first time, filling in a gap in past estimates. Much of the world's tropical forests, which house the bulk of the world's species, have been whittled down to fragments: small forest islands that no longer connect to larger habitat. According to the paper, species confined to fragments have a higher likelihood of vanishing.
Little NGO takes on goliath task: conserving the vanishing ecosystems of Paraguay
(08/12/2013) Landlocked in the navel of South America, the forests, wetlands and savannahs of Paraguay boast rich biodiversity and endemic species, yet the unique landscapes of Paraguay also face increasing threats, primarily from agricultural expansion. Controlled burns and clear cutting have become common practice as wildlands are converted for soy and cattle production. In some areas this land conversion is rapid: the Paraguayan Chaco, for instance, is being lost at a rate of 10% per year. One organization is working to reverse this trend. Para La Tierra (PLT) is a small NGO dedicated to the conservation of threatened habitats in Paraguay. Located on the Reserva Natural Laguna Blanca, in-between two of South America's most threatened habitats: the Atlantic Forest and the vast topical savannah known as the cerrado, PLT is in a unique position to champion conservation.
Climate change scattering marine species
(08/08/2013) Rising ocean temperatures are rearranging the biological make-up of our oceans, pushing species towards the poles by 7kms every year, as they chase the climates they can survive in, according to new research. The study, conducted by a working group of scientists from 17 different institutions, gathered data from seven different countries and found the warming oceans are causing marine species to alter their breeding, feeding and migration patterns.
Climate could warm more rapidly than any time in the last 65 million years
(08/01/2013) According to a new review of 27 climate models, scientists say the global climate is likely to experience a warmth as great as any in the last 65 million years, only much, much faster. According to the study published today in Science, the Earth's land temperature will rise by 4 degrees Celsius (7.2 degrees Fahrenheit) from pre-industrial levels by 2100 if we continue on our current emissions trajectory.
Habitat loss and pesticides causing decline in Europe's butterflies
(07/31/2013) Europe's grassland butterfly population has plummeted in the past two decades, new research published on Tuesday shows, with a near halving in the numbers of key species since 1990.
Over 700 species added to the threatened categories on the IUCN Red List (photos)
(07/02/2013) In another sign of the global biodiversity crisis, the IUCN Red List has added 715 species to its threatened categories of Vulnerable, Endangered, and Critically Endangered in this year's update. Some of these species were evaluated by the IUCN Red List for the first time while others saw their conditions deteriorate, such as the the white-lipped peccary (Tayassu pecari) which is now listed as Vulnerable due to overhunting, deforestation, and possibly disease. As of this year, the Red List has evaluated 70,923 of the world's species—including almost all mammals, birds, and amphibians—of which 20,934 are deemed threatened.
New maps highlight global conservation priorities
(06/25/2013) What region of the world has the most imperiled mammals? Where are the most bird species found? And where are new amphibians being discovered? Indonesia and Malaysia is the answer to the first question; the Amazon, the second; and the Andes, the third. A new study in the Proceedings of the National Academy of Sciences (PNAS) has used global data on 21,000 mammals, birds, and amphibians to create magnificent maps that highlight missing priorities for conservation.
Pesticides decimating dragonflies and other aquatic insects
(06/18/2013) While recent research (and media attention) has focused on the alleged negative impacts of pesticides on bees, the problem may be far broader according to a new study in the Proceedings of the US Academy of Sciences (PNAS). Looking at over 50 streams in Germany, France, and Australia, scientists in Europe and Australia found that pesticide contamination was capable of undercutting invertebrate biodiversity by nearly half.
Conserving the long-neglected freshwater fish of Borneo
(06/11/2013) Borneo is a vast tropical island known for orangutans, rhinos, elephants, sun bears, proboscis monkeys, hornbills, and ubiquitous leeches. Conservationists have championed all of these species (aside from the leeches) in one way or another, but like many tropical regions Borneo's freshwater species have long been neglected, despite their rich biodiversity and importance to local people. But a new organization, the Kinabatangan River Spirit Initiative, is working to change that.
Difference within common species may predict the presence of rare animals
(06/05/2013) When deciding whether or not to clear a patch of rainforest land for development, scientists are often called in to quantify how many different species exist there. But determining the number of rare and threatened species living in a section of jungle isn't easy. If they are very rare, the individual members of the species will be hard to find; if the area being surveyed is along a steep slope it may be difficult to access the area; if there are lots of species to identify, you might need to hire a dream team of biologists—each specialized within a different area of biodiversity—and that can get expensive. However a new study in the Proceedings of the Royal Society Journal by an international group of scientists suggests a more cost-effective and efficient way to rapidly assess local biodiversity.
Scientists describe over 100 new beetles from New Guinea
(06/03/2013) In a single paper, a team of researchers have succinctly described 101 new species of weevils from New Guinea, more than doubling the known species in the beetle genus, Trigonopterus. Since describing new species is hugely laborious and time-intensive, the researchers turned to a new method of species description known as 'turbo-taxonomy,' which employs a mix of DNA-sequencing and taxonomic expertise to describe species more rapidly.
Saving Gorongosa: E.O. Wilson on protecting a biodiversity hotspot in Mozambique
(05/30/2013) If you fly over the Great African Rift Valley from its northernmost point in Ethiopia, over the great national parks of Kenya and Tanzania, and follow it south to the very end, you will arrive at Gorongosa National Park in central Mozambique. Plateaus on the eastern and western sides of the park flank the lush valley in the center. Dramatic limestone cliffs, unexplored caves, wetlands, vast grasslands, rivers, lakes, and a patchwork of savanna and forest contribute to the incredible diversity of this park. What makes this place truly unique, however, is Mount Gorongosa—a towering massif that overlooks the valley below.
Over 500 scientists warn we 'are causing alarming levels of harm to our planet'
(05/27/2013) A new consensus statement by 520 scientists from around the world warns that global environmental harm is putting at risk the happiness and well-being of this and future generations.
Biosphere conservation: monumental action is critical to avert global environmental crisis
(05/20/2013) Human-caused changes to our biosphere—the global total of the world's ecosystems—are now so great and alarmingly rapid that human lives and societies undoubtedly face epic challenges in the near future as our biosphere deteriorates, planetary boundaries are reached, and tipping points exceeded. We may survive, we may painfully adapt, but it is a fair bet that grave hardship, loss, and sacrifice lay ahead. The nature and extent of impacts among human populations hinges on how successfully we respond to the biosphere crisis with extraordinary leadership, balanced solutions applied at global scales, and unprecedented cooperation—or not.
Climate change to halve habitat for over 10,000 common species
(05/13/2013) Even as concentrations of carbon dioxide in the atmosphere hit 400 parts per million (ppm) for the first time in human history last week, a new study in Nature Climate Change warns that thousands of the world's common species will suffer grave habitat loss under climate change.
Future generations to pay for our mistakes: biodiversity loss doesn't appear for decades
(04/15/2013) The biodiversity of Europe today is largely linked to environmental conditions decades ago, according to a new large-scale study in the Proceedings of the National Academy of Sciences (PNAS). Looking at various social and economic conditions from the last hundred years, scientists found that today's European species were closely aligned to environmental impacts on the continent from 1900 and 1950 instead of more recent times. The findings imply that scientists may be underestimating the total decline in global biodiversity, while future generations will inherit a natural world of our making.
How many animals do we need to keep extinction at bay?
(04/15/2013) How many animal individuals are needed to ensure a species isn't doomed to extinction even with our best conservation efforts? While no one knows exactly, scientists have created complex models to attempt an answer. They call this important threshold the "minimum viable population" and have spilled plenty of ink trying to decipher estimates, many of which fall in the thousands. However, a new study in Conservation Biology shows that some long-lived animals may not need so many individuals to retain a stable population.
Still hope for tropical biodiversity in human modified landscapes
(04/09/2013) As primary forests become increasingly rare and expensive to protect, many ecologists are looking to better management of Human Modified Landscapes (HMLs) to shepherd and shield biodiversity in the tropics. Secondary forests, selectively logged forests and lands devoted to sustainable agriculture already play an important role in conservation efforts. However, the idea that HMLs will serve as a "Noah's Ark" for biodiversity, is controversial.
Forging zoos into global conservation centers, an interview with Cristian Samper, head of WCS
(03/25/2013) The Wildlife Conservation Society (WCS) is one of the world's leading environmental organizations. Founded in 1895 (originally as the New York Zoological Society), the WCS manages 200 million acres of wild places around the globe, with over 500 field conservation projects in 65 countries, and 200 scientists on staff. The WCS also runs five facilities in New York City: the Central Park Zoo, the New York Aquarium, Prospect Park and Queens Zoos, and the world renowned Bronx Zoo.
Warnings of global ecological tipping points may be overstated
(03/05/2013) There's little evidence that the Earth is nearing a global ecological tipping point, according to a new Trends in Ecology and Evolution paper that is bound to be controversial. The authors argue that despite numerous warnings that the Earth is headed toward an ecological tipping point due to environmental stressors, such as habitat loss or climate change, it's unlikely this will occur anytime soon—at least not on land. The paper comes with a number of caveats, including that a global tipping point could occur in marine ecosystems due to ocean acidification from burning fossil fuels. In addition, regional tipping points, such as the Arctic ice melt or the Amazon rainforest drying out, are still of great concern.
Warlords, sorcery, and wildlife: an environmental artist ventures into the Congo
(02/25/2013) Last year, Roger Peet, an American artist, traveled to the Democratic Republic of Congo (DRC) to visit one of the world's most remote and wild forests. Peet spent three months in a region that is largely unknown to the outside world, but where a group of conservationists, headed by Terese and John Hart, are working diligently to create a new national park, known as Lomami. Here, the printmaker met a local warlord, discovered a downed plane, and designed a tomb for a wildlife ranger killed by disease, in addition to seeing some of the region's astounding wildlife. Notably, the burgeoning Lomami National Park is home to the world's newest monkey species, only announced by scientists last September.
Will Amazon species lose the climate change race?
(02/14/2013) Deforestation could increase the risk of biodiversity loss in the Amazon by forcing species to migrate further in order to remain at equilibrium with changing climates, says new research. "As migration models are made more realistic through the inclusion of multiple climatic, biotic, abiotic and human factors, the predicted distances between current and future climate analogues invariably increases," Kenneth Feeley, lead author of the paper published in Global Change Biology, told mongabay.com.
Scientists could name every species on Earth in 50 years
(01/28/2013) A bold new paper in Science argues that the world's species could be named and described before they vanish into extinction, though the threat of eventual extinction will remain for many, especially as climate change worsens. The scientists say that contrary to popular belief, there are more taxonomists working than ever before and there are likely less species on Earth than often reported, making finding and naming the world's species within reach this century.
The Economics of Ecosystems and Biodiversity in Local and Regional Policy - a book review
(01/21/2013) The Economics of Ecosystems and Biodiversity in Local and Regional Policy, edited by Heidi Wittmar and Haripriya Gundimeda, provides thoughtful and actionable approaches to integrate nature’s benefits into decision-making frameworks for local and regional policy and public management institutions. Filled with numerous case studies, The Economics of Ecosystems and Biodiversity in Local and Regional Policy, delivers a compendium of concepts and ideas.
Threatened Galapagos coral may predict the future of reefs worldwide
(11/07/2012) The Galapagos Islands have been famous for a century and a half, but even Charles Darwin thought the archipelago’s list of living wonders didn’t include coral reefs. It took until the 1970s before scientists realized the islands did in fact have coral, but in 1983, the year the first major report on Galapagos reef formation was published, they were almost obliterated by El Niño. This summer, a major coral survey found that some of the islands’ coral communities are showing promising signs of recovery. Their struggle to survive may tell us what is in store for the rest of the world, where almost three-quarters of corals are predicted to suffer long-term damage by 2030.
Wealthy nations, excluding U.S., pledge to double funds for biodiversity
(10/22/2012) Although negotiations came down to the wire, nations finally brokered a new deal at the 11th meeting of the Convention on Biological Diversity (CBD) in Hyderabad, India; at its heart is a pledge to double resources from wealthier countries to the developing world by 2015 to conserve embattled species and ecosystems. While no numbers were put on the table, observers say a doubling of current resources would mean around $10-12 billion a year. However, this amount is still far short of what scientists and conservation groups say is necessary to stem current extinctions.
India pledges over $60 million for biodiversity, but experts say much more needed
(10/18/2012) The Prime Minister of India, Manmohan Singh, pledged around $50 million (Rs. 264 crore) for domestic biodiversity protection, reports the Hindu. The pledge came this week at the Convention on Biological Diversity (CBD) meeting in Hyderabad, India. The CBD has set bold goals on stemming the rate of extinction worldwide, but these have suffered from a lack of funding. India also said it had set aside another $10 million (Rs. 50 crore) for biodiversity projects abroad. Still, such funds are far below what scientists say is necessary to stem ongoing extinctions.
Saving the world's species from oblivion will cost around $80 billion a year, but still a good deal
(10/11/2012) If the world is to conserve its wealth of life—species great and small, beautiful and terrible, beloved and unknown—it will cost from $3.41-4.76 billion annually in targeted conservation funds, according to a new study in Science. But that's not all, the cost of protecting and managing the world's conservation areas was estimated at an additional $76.1 billion a year.
Bird diversity at risk if 'agroforests' replaced with farmland
(09/13/2012) Agroforests contain much higher levels of bird diversity than their open agricultural counterparts, according to new research from the University of Utah. If large forests and agroforests continue to be replaced by simple open farms, bird communities will become much less specialized and entire groups may become extinct. Important roles for birds, such as pollination, pest control or seed dispersal, may remain unfilled if ongoing trends toward open agriculture continues and biodiversity decreases.
Teetering on the edge: the world's 100 most endangered species (photos)
(09/10/2012) From the Baishan fir (five left in the world) to the Sumatran rhino (around 250), a new report highlights the world's top 100 most endangered species, according to the the International Union for Conservation of Nature (IUCN) and the Zoological Society of London (ZSL). The list spans the taxonomic gamut, from fungi (Cryptomyces maximus) to amphibians (the Table Mountain ghost frog) to flowers (the Cayman Islands ghost orchid) and much more (see full list at the end of the article).
One extinction leads to another...and another
(08/28/2012) A new study in Biology Letters demonstrates that altering the relationship between a predator and its prey can cause wide-ranging ripple effects through an ecosystem, including unexpected extinctions. Species help each other, directly or indirectly, which scientists refer to as mutualism or commensalism. For example, a species’ success may rely not only upon the survival of its food source, but may also indirectly rely upon the survival of more distantly related species.
Private reserve safeguards newly discovered frogs in Ecuadorian cloud forest
(08/28/2012) Although it covers only 430 hectares (1,063 acres) of the little-known Chocó forest in Ecuador, the private reserve las Gralarias in Ecuador is home to an incredible explosion of life. Long known as a birder's paradise, the Reserva las Gralarias is now making a name for itself as a hotspot for new and endangered amphibians, as well as hundreds of stunning species of butterfly and moth. This is because the reserve is set in the perfect place for evolution to run wild: cloud forest spanning vast elevational shifts. "The pacific slope cloud forests [...] are among the most endangered habitats in the world," explains Reserva las Gralarias' founder, Jane Lyons, in a recent interview with mongabay.com.
Recommendations to save India's Western Ghats creates political stir
(08/20/2012) A massive expert panel report on the conservation of the Western Ghats has caused a political stir in India. The report, headed by noted ecologist Madhav Gadgil, recommends that the government phase out mining projects, cancel damaging hydroelectric projects, and move toward organic agriculture in ecologically-sensitive sections of the Ghats. The report, which was leaked after the government refused to release it, has yet to be implemented. Recently dubbed a UNESCO World Heritage Site, the Western Ghats is one of India's largest wildernesses and home to thousands of species, many found no-where else.
North American freshwater fish going extinct at rate over 800 times the fossil record
(08/14/2012) Since 1898 North America has lost at least 39 species of freshwater fish, according to a new study in Bioscience, and an additional 18 subspecies. Moreover, the loss of freshwater fish on the continent seems to be increasing, as the rate jumped by 25 percent since 1989, though even this data may be low.
Half of tropical forest parks losing biodiversity
(07/25/2012) Governments have set up protected areas, in part, to act as reservoirs for our Earth's stunning biodiversity; no where is this more true than in the world's tropical forests, which contain around half of our planet's species. However a new study in Nature finds that wildlife in many of the world's rainforest parks remains imperiled by human pressures both inside and outside the reserves, threatening to undercut global conservation efforts. Looking at a representative 60 protected areas across 36 tropical nations, the scientists found that about half the parks suffered an "erosion of biodiversity" over the last 20-30 years.
Experts: sustainable logging in rainforests impossible
(07/19/2012) Industrial logging in primary tropical forests that is both sustainable and profitable is impossible, argues a new study in Bioscience, which finds that the ecology of tropical hardwoods makes logging with truly sustainable practices not only impractical, but completely unprofitable. Given this, the researchers recommend industrial logging subsidies be dropped from the UN's Reducing Emissions from Deforestation and Forest Degradation (REDD+) program. The study, which adds to the growing debate about the role of logging in tropical forests, counters recent research making the case that well-managed logging in old-growth rainforests could provide a "middle way" between conservation and outright conversion of forests to monocultures or pasture.
Still time to save most species in the Brazilian Amazon
(07/12/2012) Once habitat is lost or degraded, a species doesn't just wink out of existence: it takes time, often several generations, before a species vanishes for good. A new study in Science investigates this process, called "extinction debt", in the Brazilian Amazon and finds that 80-90 percent of the predicted extinctions of birds, amphibians, and mammals have not yet occurred. But, unless urgent action is taken, the debt will be collected, and these species will vanish for good in the next few decades.
Wealthy consumption threatens species in developing countries
(07/11/2012) Consumption in wealthy nations is imperiling biodiversity abroad, according to a new study in Nature that investigates the link between international trade and biodiversity decline. The study shows how threats to biodiversity and ecosystems, located primarily in developing countries, can be connected to consumer demand for goods in wealthier nations. Some of the major commodities include coffee, cocoa, soy, beef and palm oil.
Forgotten species: the overlooked Sumatran striped rabbit
(06/28/2012) When you read the words 'Sumatra' and 'Endangered Species' in the same sentence there is a 99 percent chance that you will be reading about one of four animals: orangutans, tigers, elephants, or rhinos. These big four of Sumatra have become the rallying cry to save the island's ever-dwindling forests. This is not surprising, given that these species include some of the world's most publicly beloved animals and, in addition, they are all considered Critically Endangered by the IUCN Red List. But by dominating the headlines in Sumatra's deforestation crisis, these four species often overshadow the thousands of other species found on the island, many of which also face extinction. In fact when you read the words 'Sumatra' and 'Endangered Species' you will almost certainly not be reading about the Sumatran striped rabbit.
96 percent of the world's species remain unevaluated by the Red List
(06/28/2012) Nearly 250 species have been added to the threatened categories—i.e. Vulnerable, Endangered, and Critically Endangered—in this year's update of the International Union for Conservation of Nature's (IUCN) Red List. The 247 additions—including sixty bird species—pushes the number of threatened species globally perilously close to 20,000. However to date the Red List has only assessed 4 percent of the world's known species; for the other 96 percent, scientists simply don't know how they are faring.
Genetic analysis reveals 79 new species of sharks and rays, many likely endangered
(06/27/2012) Analyzing the DNA sequences of 4,383 specimens of sharks and rays, researchers have discovered 79 potentially new species, raising both the known diversity of this predacious family and concerns that many species are likely more imperiled than thought. Already 32 percent of open ocean sharks and rays are considered threatened with extinction by the IUCN Red List, due largely to overfishing, finning, bycatch, and prey depletion.
Cowards at Rio?: organizations decry 'pathetic' agreement
(06/20/2012) As world leaders head to Rio de Janeiro for the UN Summit on Sustainable Development, environmental and poverty groups are denouncing the last-minute text agreed on by dignitaries as "pathetic," (Greenpeace), a "damp squib" (Friends of the Earth), "a dead end" (Oxfam), and, if nothing changes, "a colossal waste of time" (WWF). "We were promised the 'future we want' but are now being presented with a 'common vision' of a polluter’s charter that will cook the planet, empty the oceans and wreck the rain forests,“ the head of Greenpeace, Kumi Naidoo, said. "This is not a foundation on which to grow economies or pull people out of poverty, it’s the last will and testament of a destructive twentieth century development model."
Scientists give world leaders 'Fs' on climate change, biodiversity, and desertification
(06/19/2012) It seems world leaders may need to retake environmental studies. As the Rio+20 Summit on Sustainable Development opens, the scientific journal, Nature, has evaluated the progress made on three treaties signed at the Rio Earth Summit in 1992: climate change, biodiversity decline, and desertification. Unfortunately the publication gives progress on all three treaties an 'F', highlighting how little progress has been made on the global environmental crisis.
Scientists: if we don't act now we're screwed
(06/07/2012) Scientists warn that the Earth may be reaching a planetary tipping point due to a unsustainable human pressures, while the UN releases a new report that finds global society has made significant progress on only four environmental issues out of ninety in the last twenty years. Climate change, overpopulation, overconsumption, and ecosystem destruction could lead to a tipping point that causes planetary collapse, according to a new paper in Nature by 22 scientists. The collapse may lead to a new planetary state that scientists say will be far harsher for human well-being, let alone survival.
Scientists to Rio+20: save biodiversity to save ourselves
(06/06/2012) World leaders need to do much more to protect the Earth's millions of species for the services they provide, according to a new scientific consensus statement in Nature based on over 1,000 research papers. Written by 17 top ecologists, the statement points out that despite growing knowledge of the importance of biodiversity for human well-being and survival, species continue to vanish at alarming rates. The statement comes just weeks before the UN'S Rio+20 Summit on Sustainable Development, which is supposed to chart a path for a less impoverished and more equitable world including an emphasis on greater environmental protections, but which has been marred by a lack of ambition.
Island bat goes extinct after Australian officials hesitate
(05/23/2012) Nights on Christmas Island in the Indian Ocean will never again be the same. The last echolocation call of a tiny bat native to the island, the Christmas Island pipistrelle (Pipistrellus murrayi), was recorded on August 26th 2009, and since then there has been only silence. Perhaps even more alarming is that nothing was done to save the species. According to a new paper in Conservation Letters the bat was lost to extinction while Australian government officials equivocated and delayed action even though they were warned repeatedly that the situation was dire. The Christmas Island pipistrelle is the first mammal to be confirmed extinct in Australia in 50 years.
Consumption, population, and declining Earth: wake-up call for Rio+20
(05/15/2012) Currently, human society is consuming natural resources as if there were one-and-a-half Earths, and not just a single blue planet, according to the most recent Living Planet Report released today. If governments and societies continue with 'business-as-usual' practices, we could be consuming three years of natural resources in 12 months by 2050. Already, this ecological debt is decimating wildlife populations worldwide, disproportionately hurting the world's poor and most vulnerable, threatening imperative resources like food and water, heating up the atmosphere, and risking global well-being.
Wildlife in the tropics plummets by over 60 percent
(05/15/2012) In 48 years wildlife populations in the tropics, the region that holds the bulk of the world's biodiversity, have fallen by an alarming 61 percent, according to the most recent update to the Living Planet Index. Produced by the World Wide Fund for Nature (WWF) and the Zoological Society of London (ZSL), the index currently tracks almost 10,000 populations of 2,688 vertebrate species (including mammals, birds, reptiles, amphibians, and fish) in both the tropics and temperate regions.
Can loggers be conservationists?
(05/10/2012) Last year researchers took the first ever publicly-released video of an African golden cat (Profelis aurata) in a Gabon rainforest. This beautiful, but elusive, feline was filmed sitting docilely for the camera and chasing a bat. The least-known of Africa's wild cat species, the African golden cat has been difficult to study because it makes its home deep in the Congo rainforest. However, researchers didn't capture the cat on video in an untrammeled, pristine forest, but in a well-managed logging concession by Precious Woods Inc., where scientist's cameras also photographed gorillas, elephants, leopards, and duikers.
Biodiversity loss cripples plant growth
(05/02/2012) For decades scientists have been warning that if global society continues with "business-as-usual" practices the result will be a mass extinction of the world's species, an extinction event some researchers say is already underway. However, the direct impacts of global biodiversity loss has been more difficult to compile. Now a new study in Nature finds that loss of plant biodiversity could cripple overall plant growth.
Doing good and staying sane amidst the global environmental crisis
(04/23/2012) Several years ago while teaching a course in environmental science a student raised her hand during our discussion of the circumstances of modern ecological collapse and posed the question, "what happens when there is no more environment?" At the time I had no response and stumbled to formulate some sort of reply based on the typical aseptic, apathetic logic with which we are programmed through education in the scientific tradition: that there will always be some sort of environment, that life has prospered through the five previous mass extinctions and that something will survive. While this may be the case, the time has come for more of us to consider the broader spectrum of what global humanity is facing as the planet’s ecology is decimated.
For Earth Day, 17 celebrated scientists on how to make a better world
(04/22/2012) Seventeen top scientists and four acclaimed conservation organizations have called for radical action to create a better world for this and future generations. Compiled by 21 past winners of the prestigious Blue Planet Prize, a new paper recommends solutions for some of the world's most pressing problems including climate change, poverty, and mass extinction. The paper, entitled Environment and Development Challenges: The Imperative to Act, was recently presented at the UN Environment Program governing council meeting in Nairobi, Kenya.
Two new frogs discovered in Philippines spur calls for more conservation efforts
(04/19/2012) Two new frogs have been discovered on the Philippine island of Leyte during a biological survey last year by Fauna and Flora International, which also recorded a wealth of other species. Discovered in November on the island's Nacolod mountain range, the frogs have yet to be named. The Philippines is one of the world's global biodiversity hotspots, yet suffers from widespread deforestation and degradation.
Featured video: Google Earth highlights imperiled coral reefs around the world
(04/18/2012) A new video by Google Earth and the World Resources Institute (WRI) highlights the world's many endangered coral reefs. A part of the WRI's Reefs at Risk program, the video highlights regional and global threats to the oceans' most biodiverse ecosystem. According to the WRI, a stunning 75 percent of the world's reefs are currently threatened.
Cinderella animals: endangered species that could be conservation stars
(04/18/2012) A cursory look at big conservation NGOs might convince the public that the only species in peril are tigers, elephants, and pandas when nothing could be further from the truth. So, why do conservation groups roll out the same flagship species over-and-over again? Simple: it is believed these species bring in donations. A new paper in Conservation Letters examines the success of using flagship species in raising money for larger conservation needs, while also pointing out that conservation groups may be overlooking an important fundraising source: "Cinderella animals."
Researchers recreate bee collapse with pesticide-laced corn syrup
(04/05/2012) Scientists with the Harvard School of Public Health (HSPH) have re-created the mysterious Colony Collapse Disorder in several honeybee hives simply by giving them small doses of a popular pesticide, imidacloprid. Bee populations have been dying mysteriously throughout North America and Europe since 2006, but the cause behind the decline, known as Colony Collapse Disorder, has eluded scientists. However, coming on the heels of two studies published last week in Science that linked bee declines to neonicotinoid pesticides, of which imidacloprid is one, the new study adds more evidence that the major player behind Colony Collapse Disorder is not disease, or mites, but pesticides that began to be widely used in the 1990s.
Smoking gun for bee collapse? popular pesticides
(03/29/2012) Commonly used pesticides may be a primary driver of the collapsing bee populations, finds two new studies in Science. The studies, one focused on honeybees and the other on bumblebees, found that even small doses of these pesticides, which target insect's central nervous system, impact bee behavior and, ultimately, their survival. The studies may have far-reaching repercussions for the regulation of agricultural chemicals, known as neonicotinoid insecticides, that have been in use since the 1990s.
Turkey's rich biodiversity at risk
(03/28/2012) Turkey: the splendor of the Hagia Sophia, the ruins of Ephesus, and the bizarre caves of the Cappadocia. For foreign travelers, Turkey is a nation of cultural, religious, and historic wonders: a place where cultures have met, clashed, and co-created. However, Turkey has another wealth that is far less known: biodiversity. Of the globe's 34 biodiversity hotspots, Turkey is almost entirely covered by three: the Caucasus, the Irano-Anatolian, and the Mediterranean. Despite its wild wealth, conservation is not a priority in Turkey and recent papers in Science and Biological Conservation warn that the current development plans in the country, which rarely take the environment into account, are imperiling its species and ecosystems.
Over 5,000 vital biodiversity sites remain unprotected
(03/22/2012) A recent study has found that half of the world's Important Bird Areas (IBAs) and Alliance for Zero Extinction (AZE) sites remain unprotected, leaving many endangered species, some on the verge of extinction, gravely vulnerable to habitat loss. Published in the open access journal PLoS ONE, the study urges governments to focus on expanding protected areas to cover the species that need it most.
Birders beware: climate change could push 600 tropical birds into extinction
(02/21/2012) There may be less birds for birders to see in the world as the planet warms. Climate change, in combination with deforestation, could send between 100 and 2,500 tropical birds to extinction before the end of century, according to new research published in Biological Conservation. The wide range depends on the extent of climate and how much habitat is lost, but researchers say the most likely range of extinctions is between 600 and 900 species, meaning about 10-14 percent of tropical birds, excluding migratory species.
The camera trap revolution: how a simple device is shaping research and conservation worldwide
(02/14/2012) I must confess to a recent addiction: camera trap photos. When the Smithsonian released 202,000 camera trap photos to the public online, I couldn’t help but spend hours transfixed by the private world of animals. There was the golden snub-monkey (Rhinopithecus roxellana), with its unmistakably blue face staring straight at you, captured on a trail in the mountains of China. Or a southern tamandua (Tamandua tetradactyla), a tree anteater that resembles a living Muppet, poking its nose in the leaf litter as sunlight plays on its head in the Peruvian Amazon. Or the dim body of a spotted hyena (Crocuta crocuta) led by jewel-like eyes in the Tanzanian night. Or the less exotic red fox (Vulpes vulpes) which admittedly appears much more exotic when shot in China in the midst of a snowstorm. Even the giant panda (Ailuropoda melanoleuca), an animal I too often connect with cartoons and stuffed animals, looks wholly real and wild when captured by camera trap: no longer a symbol or even a pudgy bear at the zoo, but a true animal with its own inner, mysterious life.
Vampire and bird frogs: discovering new amphibians in Southeast Asia's threatened forests
(02/06/2012) In 2009 researchers discovered 19,232 species new to science, most of these were plants and insects, but 148 were amphibians. Even as amphibians face unprecedented challenges—habitat loss, pollution, overharvesting, climate change, and a lethal disease called chytridiomycosis that has pushed a number of species to extinction—new amphibians are still being uncovered at surprising rates. One of the major hotspots for finding new amphibians is the dwindling tropical forests of Southeast Asia.
