(02/11/2014) Tribes in the Amazon are increasingly exposed to the outside world by choice or circumstance. The fallout of outside contact has rarely been anything less than catastrophic, resulting in untold extinction of hundreds of tribes over the centuries. For ones that survived the devastation of introduced disease and conquest, the process of acculturation transformed once proud cultures into fragmented remnants, their self-sufficiency and social cohesion stripped away, left to struggle in a new world marked by poverty and external dependence
Powered by Google, high resolution forest map reveals massive deforestation worldwide
(11/14/2013) Researchers today released a long-awaited tool that reveals the extent of forest cover loss and gain on a global scale. Powered by Google's massive computing cloud, the interactive forest map establishes a new baseline for measuring deforestation and forest recovery across all of the world's countries, biomes, and forest types. The map has far-reaching implications for efforts to slow deforestation, which accounts for roughly ten percent of greenhouse gas emissions produced by human activities, according to the authors of the paper that describes the tool and details its first findings.
Gold mining in the Amazon rainforest surges 400%
(10/28/2013) The extent of gold mining in the Peruvian Amazon has surged 400 percent since 1999 due to rocketing gold prices, wreaking havoc on forests and devastating local rivers, finds a new study published in the Proceedings of the National Academy of Sciences (PNAS). The assessment, led by Greg Asner of the Carnegie Institution for Science, is based on a combination of satellite imagery, on-the-ground field surveys, and an advanced airplane-based sensor that can accurately measure the rainforest canopy and sub-canopy vegetation at a resolution of 1.1 meters (42 inches).
Scientists build app to automatically identify species based on their calls
(07/16/2013) New technology makes it possible to automatically identify species by their vocalizations. The platform, detailed in the current issue of the journal PeerJ, has been used at sites in Puerto Rico and Costa Rica to identify frogs, insects, birds, and monkeys. Many of the animals identified by the system are typically difficult to spot in their natural environment, but audio recordings of their calls reveal not only their presence but also their activity patterns.
Stand up paddleboarding in the Amazon for conservation
(07/09/2013) This week an international team is setting off on a unique journey, aiming to be the first to descend the Amazon River using inflatable Stand Up Paddle boards. The group, led by Dr. Mika Peck, a conservation biologist from the University of Sussex with years of work in Ecuador and Colombia, includes Brazilian and Colombian researchers as well as an indigenous community leader.
The Egyptian Vulture on the Balkans – a hopeful but perilous conservation story
(07/02/2013) “They look like humans: have bare skin, wrinkles, hairdos… Maybe that’s why many people don’t like them,” says Dr. Stoyan Nikolov from the Bulgarian Society for the Protection of Birds about Egyptian vultures. Poisoned, electrocuted, shot, these rare and magnificent birds are the fastest disappearing raptors in Europe. The globally endangered species has become extinct in nine European countries in the past half a century. Dr Nikolov, the manager of an EU-funded conservation project along with more than 100 people on his team are working hard to make sure that the Egyptian vulture does not disappear from Bulgaria and Greece.
Why bioluminescent fungi glow in the dark
(06/13/2013) Aristotle (384–322 BC) reported a mysterious light, distinct from fire, emanating from decaying wood. Pliny the Elder (23–79 AD) mentioned feasting on a glowing, sweet fungus found on trees in France and, in the late fifteenth century, a Dutch consul gave accounts of Indonesian peoples using fungal fruits to illuminate forest pathways. Bioluminescent fungi have intrigued generations of observers, and a handful of scientists still carry that torch of curiosity, answering questions about how and why these mushrooms glow.
A Tale of Two Elephants: celebrating the lives and mourning the deaths of Cirrocumulus and Ngampit
(05/07/2013) On March 21st, the organization Save the Elephants posted on their Facebook page that two African elephants had been poached inside a nearby reserve: "Sad news from the north of Kenya. Usually the national reserves are safe havens for elephants, and they know it. But in the last two weeks two of our study animals have been shot inside the Buffalo Springs reserve. First an 18 year-old bull called Ngampit and then, yesterday, 23 year-old female called Cirrocumulus (from the Clouds family)."
'Suffering...without witnesses': over a quarter of a million people perished in Somali famine
(05/06/2013) A new report estimates that 258,000 people died in 2011 during a famine in Somalia, the worst of such events in 25 years and a number at least double the highest estimations during the crisis. Over half of the victims, around 133,000, were children five and under. The report, by the UN Food and Agricultural Organization (FAO), argues that the international community reacted too late and too little to stem the mass starvation brought on by government instability, conflict, high food prices, and failed rains, the last of which has been linked to climate change by some scientists.
All the world's rarest birds in one book: photo contest enlivens new guide
(05/06/2013) The World's Rarest Birds is an extraordinary bird book. 590 different bird species are classified as Endangered or Critically Endangered, with many species only existing in captivity. A new book, The World's Rarest Birds, catalogs all of these species. Each species is shown with remarkable color-photography and illustrations. Threats to species habitat are described, population estimates per species are given, and each species has a quick response (QR) code that takes the reader to a species-specific BirdLife International webpage. The book also covers 60 Data Deficient species. Data Deficient means that there exists little to no information on the relative abundance and distribution of the species.
Conservation without supervision: Peruvian community group creates and patrols its own protected area
(04/30/2013) When we think of conservation areas, many of us think of iconic National Parks overseen by uniformed government employees or wilderness areas purchased and run from afar by big-donor organizations like The Nature Conservancy, Wildlife Conservation Society, WWF, or Conservation International. But what happens to ecosystems and wildlife in areas where there's a total lack of government presence and no money coming in for its protection? This is the story of one rural Peruvian community that took conservation matters into their own hands, with a little help from a dedicated pair of primate researchers, in order to protect a high biodiversity cloud forest.
What if companies actually had to compensate society for environmental destruction?
(04/29/2013) The environment is a public good. We all share and depend on clean water, a stable atmosphere, and abundant biodiversity for survival, not to mention health and societal well-being. But under our current global economy, industries can often destroy and pollute the environment—degrading public health and communities—without paying adequate compensation to the public good. Economists call this process "externalizing costs," i.e. the cost of environmental degradation in many cases is borne by society, instead of the companies that cause it. A new report from TEEB (The Economics of Ecosystems and Biodiversity), conducted by Trucost, highlights the scale of the problem: unpriced natural capital (i.e. that which is not taken into account by the global market) was worth $7.3 trillion in 2009, equal to 13 percent of that year's global economic output.
Working to save the mystery antelope that's little bigger than a pet cat (photos)
(04/25/2013) Little is known about the silver dik-dik (Madoqua piacentinii) population that roams the dense coastal bushlands of eastern Africa, but experts are working to learn more about the mysterious species. Weighing little more than a domestic cat, the small antelopes are found in a long, narrow coastal strip spreading across 250 kilometers (155 miles) from Somalia's capital of Mogadishu north to the port town of Hobyo. This coastal strip is known as the Hobyo Grassland and Shrubland eco-region, according to the WWF.
The river of plenty: uncovering the secrets of the amazing Mekong
(04/23/2013) Home to giant catfish and stingrays, feeding over 60 million people, and with the largest abundance of freshwater fish in the world, the Mekong River, and its numerous tributaries, brings food, culture, and life to much of Southeast Asia. Despite this, little is known about the biodiversity and ecosystems of the Mekong, which is second only to the Amazon in terms of freshwater biodiversity. Meanwhile, the river is facing an existential crisis in the form of 77 proposed dams, while population growth, pollution, and development further imperil this understudied, but vast, ecosystem.
Saviors or villains: controversy erupts as New Zealand plans to drop poison over Critically Endangered frog habitat
(04/10/2013) New Zealand's Department of Conservation (DOC) is facing a backlash over plans to aerially drop a controversial poison, known as 1080, over the habitat of two endangered, prehistoric, and truly bizarre frog species, Archey's and Hochsetter's frogs, on Mount Moehau. Used in New Zealand to kill populations of invasive mammals, such as rats and the Australian long-tailed possum, 1080 has become an increasingly emotive issue in New Zealand, not just splitting the government and environmentalists, but environmental groups among themselves. Critics allege that the poison, for which there is no antidote, decimates local animals as well as invasives, while proponents say the drops are the best way to control invasive mammals that kill endangered species like birds and frogs and may spread bovine tuberculosis (TB).
An insidious threat to tropical forests: over-hunting endangers tree species in Asia and Africa
(04/04/2013) A fruit falls to the floor in a rainforest. It waits. And waits. Inside the fruit is a seed, and like most seeds in tropical forests, this one needs an animal—a good-sized animal—to move it to a new place where it can germinate and grow. But it may be waiting in vain. Hunting and poaching has decimated many mammal and bird populations across the tropics, and according to two new studies the loss of these important seed-disperser are imperiling the very nature of rainforests.
Domesticated bees do not replace declining wild insects as agricultural pollinators
(04/03/2013) Sprinkled with pollen, buzzing bees fly from one blossom to another, collecting sweet nectar from brilliantly colored flowers. Bees tend to symbolize the pollination process, but there are many wild insects that carry out the same function. Unfortunately, wild insect populations are in decline, and, according to a recent study, adding more honey bees may not be a viable solution.
By 2050 much of the Arctic could be green
(04/01/2013) Warming about twice as fast as the rest of the world, the Arctic is already undergoing massive upheavals from climate change: summer sea ice is thinning and vanishing, land based ice sheets are melting, and sea levels are rising. Now a new study in Nature Climate Change predicts that vegetation cover in the Arctic could expand by over 50 percent by 2050. Although increased vegetation would sequester additional carbon, this would be more-than-offset by the loss of the albedo effect, whereby sunlight bounces off white (snow and ice covered) parts of the Earth.
Humans killed over 10 percent of the world's bird species when they colonized the Pacific Islands
(03/25/2013) Around 4,000 years ago intrepid Polynesian seafarers made their way into an untamed wilderness: the far-flung Pacific Islands. Over a thousands or so years, they rowed from one island to another, stepping on shores never yet seen by humans. While this vast colonization brought about a new era of human history, it also ended the existence of well-over a thousand bird species according to a new study in the Proceedings of the National Academy of Sciences (PNAS).
Planet organic: achieving sustainable food security and environmental gains
(03/19/2013) The global farmland area certified organic has expanded more than threefold to 37 million hectares since 1999, according to new research conducted by the Worldwatch Institute. The Institute argues that organic farming has the potential to contribute to sustainable food security by improving nutrition intake and sustaining rural livelihoods, while reducing vulnerability to climate change and enhancing biodiversity.
Into the unknown mountains of Cambodia: rare birds, rice wine, and talk of tigers
(03/14/2013) Ringed with forested mountains forming the borders with Laos and Vietnam, the northeast corner of Cambodia has been an intriguing blank spot among my extensive travels through the country. Nestled up against this frontier is Virachey National Park, created in 1993. I began searching for a way to explore this area a couple of years ago, hoping to connect with conservation NGOs to get me into the park; no one seemed to know much about it. I learned that the area had been written off by these groups due to massive land concessions given to logging and rubber concerns. The World Bank abandoned its 8-year effort to create a management scheme for Virachey after the concessions were granted in 2007. A moratorium on the concessions is temporarily in place, but illegal logging incursions into the park continue.
Seeing the forest through the elephants: slaughtered elephants taking rainforest trees with them
(03/11/2013) Elephants are vanishing. The booming illegal ivory trade is decimating the world's largest land animal, but no place has been harder hit than the Congo basin and its forest elephants (Loxodonta cyclotis). The numbers are staggering: a single park in Gabon, Minkebe National Park, has seen 11,100 forest elephants killed in the last eight years; Okapi Faunal Reserve in the Democratic Republic of the Congo has lost 75 percent of its elephants in fifteen years; and a new study in PLoS ONE estimates that in total 60 percent of the world's forest elephants have been killed in the last decade alone. But what does that mean for the Congo forest?
Extinction warning: racing to save the little dodo from its cousin's fate
(03/04/2013) Sometime in the late 1600s the world's last dodo perished on the island of Mauritius. No one knows how it spent its final moments—rather in the grip of some invasive predator or simply fading away from loneliness—but with its passing came an icon of extinction, that final breath passed by the last of its kind. The dodo, a giant flightless pigeon, was a marvel of the animal world: now another island ground pigeon, known as the little dodo, is facing its namesake's fate. Found only in Samoa, composed of ten islands, the bird has many names: the tooth-billed pigeon, the Manumea (local name), and Didunculus ("little dodo") strigirostris, which lead one scientist to Christen it the Dodlet. But according to recent surveys without rapid action the Dodlet may soon be as extinct as the dodo.
Scientists: stop treating population growth as a 'given' and empower women
(02/27/2013) Climate change, biodiversity loss, resource depletion, water scarcity, and land issues: almost all of the world's environmental problems are underpinned by too many people inhabiting a finite planet. A new study in the Proceedings of the Royal Society B warns that overpopulation—combined with over-consumption—is threatening to push the entire globe into "a collapse of global civilization." But cultural changes, especially more empowerment of women and access to contraceptives, may hold the key to reducing population growth and eventual sustainability.
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.
Jaguars, tapirs, oh my!: Amazon explorer films shocking wildlife bonanza in threatened forest
(02/19/2013) Watching a new video by Amazon explorer, Paul Rosolie, one feels transported into a hidden world of stalking jaguars, heavyweight tapirs, and daylight-wandering giant armadillos. This is the Amazon as one imagines it as a child: still full of wild things. In just four weeks at a single colpa (or clay lick where mammals and birds gather) on the lower Las Piedras River, Rosolie and his team captured 30 Amazonian species on video, including seven imperiled species. However, the very spot Rosolie and his team filmed is under threat: the lower Las Piedras River is being infiltrated by loggers, miners, and farmers following the construction of the Trans-Amazon highway.
Pity the pangolin: little-known mammal most common victim of the wildlife trade
(02/11/2013) Last year tens-of-thousands of elephants and hundreds of rhinos were butchered to feed the growing appetite of the illegal wildlife trade. This black market, largely centered in East Asia, also devoured tigers, sharks, leopards, turtles, snakes, and hundreds of other animals. Estimated at $19 billion annually, the booming trade has periodically captured global media attention, even receiving a high-profile speech by U.S. Secretary of State, Hillary Clinton, last year. But the biggest mammal victim of the wildlife trade is not elephants, rhinos, or tigers, but an animal that receives little notice and even less press: the pangolin. If that name doesn't ring a bell, you're not alone.
Asian bear farming: breaking the cycle of exploitation (warning: graphic images)
(01/31/2013) In the forests of Asia, bears are being captured. These captives will be sent to bear farms, most unregulated and illegal, where they will be kept alive in a small cage, locked away for life. Their bodies will be used as renewable natural resources, from which profit will be made through the extraction of internal organs and fluids. By surgically inserting a permanent catheter into the bears' gall bladders, "farmers" extract several ounces of their bile. In a cycle of exploitation across east Asia, traditional medicine shops receive these daily shipments of bear bile products, while consumers support the industry through the purchase of these products, sustaining a supply-and-demand chain that puts more and more bears in cages as wild populations dwindle.
Controversial research outlines physics behind how forests may bring rain
(01/30/2013) It took over two-and-a-half-years for the journal Atmospheric Chemistry and Physics to finally accept a paper outlining a new meteorological hypothesis in which condensation, not temperature, drives winds. If proven correct, the hypothesis could have massive ramifications on global policy—not to mention meteorology—as essentially the hypothesis means that the world's forest play a major role in driving precipitation from the coast into a continent's interior. The theory, known as the biotic pump, was first developed in 2006 by two Russian scientists, Victor Gorshkov and Anastassia Makarieva of the St. Petersburg Nuclear Physics, but the two have faced major pushback and delays in their attempt to put the theory before the greater scientific community.
Beyond the resorts: traveling the real and wild Dominican Republic (photos)
(01/29/2013) For its stunning variety of ecosystems, the Dominican Republic is like a continent squished into half an island. Lowland rainforests, cloud forests, pine forests, dry forests, mangroves, savannah, coastal lagoons, salt lakes, a rift valley, karst land formations, four mountain ranges—including the highest mountain in the Caribbean—and not to mention some of the best beaches, snorkeling, and scuba diving in the hemisphere can all be reached within just a few hours drive of the capital, Santo Domingo. Yet, bizarrely, most tourists who visit the Dominican Republic never venture out of their all-inclusive resort, missing out on some of the most stunning landscapes—and accessible wildlife viewing—in the Caribbean.
Fish unable to pass through dams in U.S. presents 'cautionary tale' for developing world
(01/17/2013) Dams create a largely impenetrable barrier for fish even when the dams were installed with specially-built passages, according to a new study in Conservation Letters. The scientists found that migrating fish largely failed to use the passages in the U.S., resulting in far fewer moving through the state-of-the-art hydroelectric dams than had been promised. The researchers say that their findings are a "cautionary tale" for developing nations.
Bloodsucking flies help scientists identify rare, hard-to-find mammals
(01/16/2013) Last year scientists released a study that is likely to revolutionize how conservationists track elusive species. Researchers extracted the recently sucked blood of terrestrial leeches in Vietnam's remote Annamite Mountains and looked at the DNA of what they'd been feeding on: remarkably researchers were able to identify a number of endangered and rarely-seen mammals. In fact two of the species gleaned from these blood-meals had been discovered by scientists as late as the 1990s. In the past, trying to find rare and shy jungle animals required many man hours and a lot of funding. While the increasing use of remote camera traps has allowed scientists to expand their search, DNA sampling from leeches could be the next big step in simplifying (and cheapening) the quest for tracking the world's mammals.
Paradigm shift needed to avert global environmental collapse, according to author of new book The Blueprint: Averting Global Collapse
(01/10/2013) Global strategist, trained educator, and international lecturer Daniel Rirdan set out to create a plan addressing the future of our planet. His book The Blueprint: Averting Global Collapse, published this year, does just that. "It has been a sixty hour a week routine," Rirdan told mongabay.com in a recent interview. "Basically, I would wake up with the burden of the world on my shoulders and go to sleep with it. It went on like this for eighteen months." It becomes apparent when reading The Blueprint that it was indeed a monumental undertaking.
Mercury hurts birds and people: what we can learn from studying our feathered friends
(01/07/2013) Birds aren't that different from people. We learn from our parents, just like zebra finches learn songs from their fathers. We are active and noisy during the day, like birds, and we can also be territorial. Also like birds, we try to attract mates through colorful displays and beautiful songs. Birds are sensitive to pollution in their environment just like we are: harmful elements such as mercury wreak similar havoc on human and bird biology alike. Because our species share so many attributes, studying birds illustrates the connections between them and us.
Advanced technology reveals massive tree die-off in remote, unexplored parts of the Amazon
(12/12/2012) Severe drought conditions in 2010 appear to have substantially increased tree mortality in the Western Amazon, a region thought largely immune from the worst effects of changes occurring in other parts of the world's largest rainforest, reported research presented last week at the fall meeting of the American Geophysical Union (AGU). The findings suggest that the Amazon may face higher-the-expected vulnerability to climate change, potentially undercutting its ability to help mitigate greenhouse gas emissions by absorbing carbon dioxide through faster growth.
Uncontacted tribes still exist, but extinction threat looms
(12/11/2012) The world is more interconnected than ever. Globally, there are six billion cell phone subscribers and 900 million Facebook users. Nearly 32 million people follow Lady Gaga on Twitter. Given this content it may seem hard to believe that there remain people who have never had contact with the outside world. Yet such people do exist today. Most of them live in the most remote parts of the world's wildest forests. One of this year's best paperback books takes a close look at one uncontacted group — the Arrow People of the Brazilian Amazon. Written by veteran journalist Scott Wallace, The Unconquered is a gripping first-person account of a journey to learn more about this little-known tribe.
Dams are rapidly damning the Amazon
(12/08/2012) Dam-builders seeking to unlock the hydroelectric potential of the Amazon are putting the world's mightiest river and rainforest at risk, suggests a new assessment that charts the rapid expansion of dams in the region.
Global decline of big trees in old-growth forests worrying, argue scientists
(12/06/2012) The decline of large trees is putting biodiversity and forest health at risk globally, warn researchers writing in the journal Science.
Deforestation rate falls across Amazon rainforest countries
(12/06/2012) The average annual rate of deforestation across Amazon rainforest countries dropped sharply in the second half of the 2000s, reports a comprehensive new assessment of the region's forest cover and drivers of deforestation. While the drop in deforestation in the Brazilian Amazon has been widely reported, several other Amazon countries saw their rates of forest loss drop as well, according to the report, which was published by a coalition of 11 Latin American civil society groups and research institutions that form the Amazonian Network of Georeferenced Socio-Environmental Information (RAISG).
Forests, farming, and sprawl: the struggle over land in an Amazonian metropolis
(12/04/2012) The city of Parauapebas, Brazil is booming: built over the remains of the Amazon rainforest, the metropolis has grown 75-fold in less than 25 years, from 2,000 people upwards of 150,000. But little time for urban planning and both a spatial and mental distance from the federal government has created a frontier town where small-scale farmers struggle to survive against racing sprawl, legal and illegal mining, and a lack of investment in environmental protection. Forests, biodiversity, and subsistence farmers have all suffered under the battle for land. In this, Parauapebas may represent a microcosm both of Brazil's ongoing problems (social inequality, environmental degradation, and deforestation) and opportunity (poverty alleviation, reforestation, and environmental enforcement).
Jeff Corwin talks sharks
(12/04/2012) Sharks are among the most feared of all the world's predators, yet humans kill tens of millions of sharks for every person who falls victim to shark attack. Part of our fear stems from lack of understanding. A new eBook however tries to change that. Jeff Corwin, an Emmy Award Winning TV host, has this week released Jeff's Explorer Series: SHARKS, the first of a new eBook series, which Corwin likens to the 21st century version of an encyclopedia. The eBook is rich with video, images, and text. It is narrated by Corwin.
Africa's great savannahs may be more endangered than the world's rainforests
(12/04/2012) Few of the world's ecosystems are more iconic than Africa's sprawling savannahs home to elephants, giraffes, rhinos, and the undisputed king of the animal kingdom: lions. This wild realm, where megafauna still roam in abundance, has inspired everyone from Ernest Hemingway to Karen Blixen, and David Livingstone to Theodore Roosevelt. Today it is the heart of Africa's wildlife tourism and includes staunch defenders such as Richard Leakey, Michael Fay, and the Jouberts. Despite this, the ecosystem has received less media attention than imperiled ecosystems like rainforests. But a ground-breaking study in Biodiversity Conservation finds that 75 percent of these large-scale intact grasslands have been lost, at least from the lion's point of view.
Tropical deforestation emissions were 3 billion tons/yr from 2000-2005
(12/03/2012) Two prominent groups of researchers have reached a consensus estimate for emissions from tropical deforestation between 2000 and 2005.
Organic farming keeps carbon out of the atmosphere
(11/28/2012) With the worst effects of climate change, we are seeing how pollution hurts both human health and the environment but there is good news: a new study shows that organic farming stores more greenhouse gases in the soil than non-organic farming. By switching to organic methods, many farmers across the globe may be helping to solve the climate crisis at the same time as they improve soil quality and avoid the use of pesticides.
Could marine cloud machines cool the planet?
(11/26/2012) In 1990, British cloud physicist John Latham published a paper arguing he could cool global climate by brightening clouds over the ocean. Most colleagues ignored the paper, titled 'Control global warming?'—probably because this thing called global warming was not yet a hot topic. Now, more than two decades later, Latham continues to develop what has become one of the most promising and controversial ideas in climate control. 'Marine cloud brightening' might sound benign, but hairs rise when it’s called 'geoengineering.'
Could rebuilding global fisheries save hundreds of billions of dollars?
(11/26/2012) Global fisheries are gutting the world economy by US$13 billion annually, according to an economic analysis published July 13 in the journal PLoS ONE. National subsidies that encourage overfishing cause the most losses, the analysis claims. However, researchers believe that allowing fish stocks to rebuild and making fishing more efficient could reverse these losses, leading to net gains of US$600 to US$1,400 billion within 50 years. Such savings won’t come cheaply, the analysis suggests. Rebuilding fisheries worldwide could cost US$130 to US$292 billion, the researchers estimate. Most of the cost would go toward retraining or retiring nearly half of the world’s 35 million fisheries workers.
Endangered muriqui monkeys in Brazil full of surprises
(11/26/2012) On paper, the northern muriquis (Brachyteles hypoxanthus) look like a conservation comeback story. Three decades ago, only 60 of the gentle, tree-dwelling primates lived in a fragment of the Atlantic Forest along the eastern coast of Brazil. Now there are more than 300. But numbers don’t tell the whole story, according to anthropologist Karen Strier and theoretical ecologist Anthony Ives of the University of Wisconsin, Madison. The pair analyzed 28 years of data on the demographics of the muriquis, one of the longest studies of its kind. They found surprising patterns about birth and death rates, sex ratios, and even how often the monkeys venture out of their trees. These findings raise questions about the muriquis’ long-term survival and how best to protect them, the scientists wrote in the Sept 17 issue of PLoS ONE.
Forests worldwide near tipping-point from drought
(11/23/2012) Forests worldwide are at 'equally high risk' to die-off from drought conditions, warns a new study published this week in the journal Nature. The study, conducted by an international team of scientists, assessed the specific physiological effects of drought on 226 tree species at 81 sites in different biomes around the world. It found that 70 percent of the species sampled are particularly vulnerable to reduction in water availability. With drought conditions increasing around the globe due to climate change and deforestation, the research suggests large swathes of the world's forests — and the services they afford — may be approaching a tipping point.
Wolves, mole rats, and nyala: the struggle to conserve Ethiopia's highlands
(11/20/2012) There is a place in the world where wolves live almost entirely off mountain rodents, lions dwell in forests, and freshwater rolls downstream to 12 million people, but the place—Ethiopia's Bale Mountains National Park—remains imperiled by a lack of legal boundaries and encroachment by a growing human population. "Much of the land in Africa above 3,000 meters has been altered or degraded to the point where it isn’t able to perform most of the ecosystem functions that it is designed to do. Bale, although under threat and already impacted to a degree by anthropogenic activities, is still able to perform its most important ecosystem functions, and as such ranks among only a handful of representative alpine ecosystems in Africa."
World Bank: 4 degrees Celsius warming would be miserable
(11/20/2012) A new report by the World Bank paints a bleak picture of life on Earth in 80 years: global temperatures have risen by 4 degrees Celsius spurring rapidly rising sea levels and devastating droughts. Global agriculture is under constant threat; economies have been hampered; coastal cities are repeatedly flooded; coral reefs are dissolving from ocean acidification; and species worldwide are vanishing. This, according to the World Bank, is where we are headed even if all of the world's nations meet their pledges on cutting greenhouse gas emissions. However, the report also notes that with swift, aggressive action it's still possible to ensure that global temperatures don't rise above 4 degrees Celsius.
