(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.
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.
On edge of extinction, could drones and technology save the Little Dodo?
(02/10/2014) Almost nothing is known about the little dodo, a large, archaic, pigeon-like bird found only on the islands of Samoa. Worse still, this truly bizarre bird is on the verge of extinction, following the fate of its much more famous relative, the dodo bird. Recently, conservationists estimated that fewer than 200 survived on the island and maybe far fewer; frustratingly, sightings of the bird have been almost non-existent in recent years. But conservation efforts were buoyed this December when researchers stumbled on a juvenile little dodo hanging out in a tree. Not only was this an important sighting of a nearly-extinct species, but even more so it proved the species is still successfully breeding. In other words: there is still time to save the species from extinction so long as conservationists are able to raise the funds needed.
Next big idea in forest conservation? Connecting forest fragments
(01/31/2014) Dr. Stuart Pimm is an expert in extinctions: why they happen, how fast they happen, and how they can be prevented. Reconnecting forest fragments and avoiding fragmentation, according to Pimm, are among the most crucial things we can do to conserve global biodiversity. His organization SavingSpecies identifies areas at-risk for extinctions and helps local organizations fundraise so they can protect and restore habitats and safeguard biodiversity.
Predator appreciation: how saving lions, tigers, and polar bears could rescue ourselves
(01/29/2014) In the new book, In Predatory Light: Lions and Tigers and Polar Bears, authors Elizabeth Marshall Thomas, Sy Montgomery, and John Houston, and photographers Cyril Christo and Marie Wilkinson share with us an impassioned and detailed appeal to appreciate three of the world's biggest predators: lions, tigers, and polar bears. Through lengthy discussions, combining themes from scientific conservation to local community folklore, In Predatory Light takes us step by step deeper into the wild world of these awe-inspiring carnivores and their varied plight as they facedown extinction.
The smoothtooth blacktip shark and four other species rediscovered in markets
(01/21/2014) Scientific American) magazine recently ran an article on the rediscovery of the smoothtooth blacktip shark (Carcharhinus leiodon) in a Kuwaiti fish market. Believed extinct for over 100 years, the smoothtooth had not been seen since the naturalist Wilhelm Hein returned from a trip to Yemen in 1902. With its reappearance, scientists scoured Kuwaiti markets and discovered an astounding 47 individual smoothtooth blacktips.
Jaguars in Argentine Chaco on verge of local extinction
(12/23/2013) The majestic jaguar (Panthera onca), the largest of the New World cats, is found as far north as the southern states of the US, and as far south as northern Argentina. In the past jaguars ranged 1,500 kilometers (930 miles) further south, but their range has shrunk as habitat loss and human disturbance have increased. Overall, jaguars are classified as Near Threatened by the IUCN, but the level of risk facing jaguars varies by region. Populations in Argentina, at the present-day southern range limit, have previously been identified as some of the most threatened of them all.
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.
Bonobos: the Congo Basin's great gardeners
(12/11/2013) The survival of primary forests depends on many overlapping interactions. Among these interactions include tropical gardeners, like the bonobo (Pan pansicus) in the Congo Basin, according to a new study in the Journal of Tropical Ecology. Bonobos are known as a keystone species, vital to the diversification and existence of their forests.
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.
Consumer report uncovers why people buy rhino horn
(11/26/2013) The rhinoceros is one of the largest and most iconic animals to roam the earth. However, poaching for their horn, erroneously believed to have medicinal value, has led the IUCN Red List to classify three of the world's five species as Critically Endangered. But, a new consumer report by the wildlife trade monitoring network, TRAFFIC, finds that rhino horn consumers in Vietnam buy the illegal product as much to raise their social status as to attempt to treat a fever or hangover.
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.
Strange mouth-brooding frog driven to extinction by disease
(11/21/2013) An unusual species of mouth-brooding frog was likely driven to extinction by the fungus Batrachochytrium dendrobatidis (Bd), making an unusual example of 'extinction by infection', argue scientists writing in the open-access journal PLOS ONE. Rhinoderma rufum has not been seen in the wild since 1980.
Nearly half a million seabirds die in gillnets every year, but solutions exist
(11/18/2013) A recent study from the Biological Conservation journal brings shocking news: every year across the globe, an estimated 400,000 seabirds are killed by gillnets. Gillnets, a common term for any net used to entangle and catch fish, are used all over the world, and at any depth. These nets, whether used in subsistence or commercial fishing, trap anything that swims through them. When unintended marine wildlife, or "bycatch," is caught in these nets, the results can be significant.
New bat species discovered in Brazil leaves another at risk
(11/15/2013) A team of researchers has discovered a new species of bat in Brazil, which has put a previously known species, Bokermann's nectar bat (Lonchophylla bokermanni), at risk of extinction. Long thought to comprise one species, the bat populations of the Atlantic Forest and the Cerrado – the tropical savannah of Brazil's interior - are in fact distinct from one another, according to a new study in Zootaxa. Scientists now say the Atlantic Forest's population represents a newly described species, which they have dubbed Peracchi's nectar bat (Lonchophylla peracchii).
Giant turtle-devouring duck-billed platypus discovered
(11/04/2013) Based on a single tooth from Australia, scientists believe they have discovered a giant, meter-long (3.3 feet) duck-billed platypus that likely fed on fish, frogs, and even turtles, according to a new study in Journal of Vertebrate Paleontology. At least twice the size of a modern duckbilled platypus, the scientists say the extinct giant likely lived between 15 and 5 million years ago.
Thought-to-be-extinct 'halloween' frog rediscovered in Costa Rica
(11/04/2013) A breeding population of a critically endangered harlequin toad thought to be extinct in Costa Rica has been discovered in a tract of highland forest in the Central American country, reports a paper published in Amphibia-Reptilia. Atelopus varius, an orange-and-black harlequin toad, was once relatively common from central Costa Rica to western Panama. But beginning in the 1980's the species experienced a rapid population collapse across most of its range.
First study of little-known mammal reveals climate change threat
(10/28/2013) One of the world's least-known flying foxes could face extinction by rising seas and changing precipitation patterns due to global warming, according to a new study in Zookeys. The research, headed by Donald Buden with the College of Micronesia, is the first in-depth study of the resident bats of the remote Mortlock Islands, a part of the Federated States of Micronesia.
Small invertebrates could be key to uncovering the mysteries of killer amphibian fungus
(10/22/2013) In 2004, the first-ever Global Amphibian Assessment (GAA) reviewed all 5,743 amphibian species known to science and concluded that 32% were threatened with extinction - a number far exceeding corresponding figures for birds and mammals (12 to 23% respectively). In addition to the usual culprits of climate change and habitat destruction, a startling 92.5% of amphibians listed as Critically Endangered were found to be undergoing enigmatic declines linked to an unexpected perpetrator - the chytrid fungus, Batrachochytrium dendrobatidis (Bd).
Climate change pushing tropical trees upslope 'exactly as predicted'
(09/27/2013) Tropical tree communities are moving up mountainsides to cooler habitats as temperatures rise, a new study in Global Change Biology has found. By examining the tree species present in ten one-hectare plots at various intervals over a decade, researchers found that the proportion of lowland species increased in the plots at higher elevations. The study, which was undertaken in Volcan Barva, Costa Rica, adds to a growing body of evidence that climate change is having an impact on species range distributions.
'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?
Global warming may ‘flatten’ rainforests
(09/12/2013) Climate change may push canopy-dwelling plants and animals out of the tree-tops due to rising temperatures and drier conditions, argues a new study published in Proceedings of the Royal Society B. The development may be akin to 'flattening' the tiered vegetation structure that characterizes the rainforest ecosystem.
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.
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.
Nutrient deficiency in Amazon rainforest linked to megafauna extinction
(08/12/2013) Around twelve thousand of years ago, the Amazon was home to a menagerie of giant creatures: the heavily armored glyptodons, the elephant-sized ground sloth, and the rhino-like toxodons among others. But by 10,000 B.C. these monsters were largely gone, possibly due to overhunting by humans or climatic changes. There's no question that the rapid extinction of these megafauna changed the environment, but a new study in Nature Geoscience posits a novel theory: did the mass extinction of big mammals lead to nutrient deficiency, especially of nitrogen, in parts of the Amazon rainforest?
Florida declares two butterfly species extinct as pollinator crisis worsens
(08/01/2013) Conservationist’s faced a crushing blow last month as two butterfly species native to Florida were declared extinct. 'Occasionally, these types of butterflies disappear for long periods of time but are rediscovered in another location,' said Larry Williams, U.S. Fish and Wildlife state supervisor for ecological services. We think it’s apparent now these two species are extinct.'
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.
Palm oil drives Malaysian rainforest tree to extinction
(07/30/2013) Oil palm plantations have extinguished the last habitat of a rainforest tree in Malaysia. Last week the Forest Research Institute Malaysia (FRIM), a state agency, announced that the last stands of keruing paya (Dipterocarpus coriaceus) in Peninsular Malaysia were wiped out when Bikam forest reserve in Perak was cleared for oil palm plantations.
Rare animal species and Buddhist monks in danger of losing their home to cement quarry
(07/22/2013) An international cement company Lafarge, winner of a Green Initiative award, is considering quarrying a cave in Malaysia which is the sole home of a critically endangered species. The proposed operations also threaten a Buddhist monastery near the cave where monks are facing eviction. Kanthan cave in Peninsular Malaysia is located in a limestone hill, already extensively quarried for the production of cement by Lafarge. The cave, just as most karst caves in Southeast Asia, harbors a unique ecosystem. One of the rare endemic organisms is the Kanthan Cave trapdoor spider (Liphistius kanthan), which was just designated as Critically Endangered by the IUCN Red List.
Losing just one pollinator species leads to big plant declines
(07/22/2013) A shocking new study finds that losing just one pollinator species could lead to major declines in plant productivity, a finding that has broad implications for biodiversity conservation. Looking at ten bumblebee species in Colorado alpine meadows, two scientists found that removing a single bee species cut flower seed production by one-third. Pollinators worldwide are in major trouble as they are hit by habitat loss, pesticides, disease and other impacts. In fact, the EU has recently banned several pesticides that have been linked to the global bee decline.
Madagascar occupied by humans 2,500 years earlier than previously thought
(07/22/2013) New research indicates that Madagascar was occupied some 2,500 years earlier than previously established. The findings, published in Proceedings of the National Academy of Sciences, suggests a more complex view of the human role in the extinction of the island's mega-fauna. A large body of research holds that village communities began to appear in Madagascar around 500 AD. These were established by people of Indonesian and East African heritage, according to past studies that found linguistic similarities between the Malagasy languages of southeastern Borneo as well as genetic markers tying modern-day Malagasy people to both Indonesia and East Africa. But there have been plenty of hints that people came to the world's third largest island well before 500 AD.
Losing our monarchs: iconic monarch butterfly down to lowest numbers in 20 years
(07/15/2013) In the next few months, the beating of fragile fiery orange and black wings will transport the monarch butterfly south. But the number of monarch butterflies (Danaus plexippus) reaching their final destination has steadily declined, dropping to its lowest level in two decades last winter, according to a recent survey.
Vocal-sac breeding frog possibly extinct
(07/02/2013) Somewhere in the wet pine forests of Chile, a male frog is gulping-up a bunch of eggs. No he's not eating them, he's just being a good dad. Darwin's frogs are known for their unique parenting-style: tadpoles are incubated in the vocal sac of the father. First recorded by Charles Darwin during his world famous voyage aboard the Beagle, the amphibians were common in the native Chilean pine forests until the last few decades. Now, scientists believe that one of the two species, the northern Darwin's frog (Rhinoderma rufum), may have vanished for good. And the other is hanging on by a thread.
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.
Syrian bald ibis may be down to a single bird
(06/11/2013) The eastern population of northern bald ibises (Geronticus eremita) has likely fallen to a single breeding bird, reports conservationists monitoring the dwindling flock. The population had believed to be obliterated starting from 1989 until a small group was discovered in 2002 in Syria. However, it now appears that this last group is vanishing one-by-one despite efforts by conservation groups to sustain the distinct population.
The comeback kids: the role of zoos in saving species from oblivion (photos)
(06/03/2013) While many people may view zoos first and foremost as attractions, these institutions have a long history of supporting and instigating conservation work, including saving species from extinction that have vanished from their wild habitat. But such efforts require not just dedication and patience, but herculean organizational efforts. Enter, the World Association of Zoos and Aquariums (WAZA), which works with zoos and aquariums to set up conservation programs and track endangered species in captivity.
Loss of big fruit-eating birds impacting trees in endangered rainforests
(05/31/2013) The extinction of large, fruit-eating birds in fragments of Brazil's Atlantic rainforest has caused palm trees to produce smaller seeds over the past century, impacting forest ecology, finds a study published in the journal Science.
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.
Plants re-grow after five centuries under the ice
(05/27/2013) While monitoring the retreat of the Teardrop Glacier in the Canadian Arctic, scientists have found that recently unfrozen plants, some of which had been under ice since the reign of Henry VIII, were capable of new growth.
Could the Tasmanian tiger be hiding out in New Guinea?
(05/20/2013) Many people still believe the Tasmanian tiger (Thylacinus cynocephalus) survives in the wilds of Tasmania, even though the species was declared extinct over eighty years ago. Sightings and reports of the elusive carnivorous marsupial, which was the top predator on the island, pop-up almost as frequently as those of Bigfoot in North America, but to date no definitive evidence has emerged of its survival. Yet, a noted cryptozoologist (one who searches for hidden animals), Dr. Karl Shuker, wrote recently that tiger hunters should perhaps turn their attention to a different island: New Guinea.
Aquarium launches desperate search to save a species down to 3 individuals
(05/10/2013) Aquarists at ZSL London Zoo have launched a worldwide appeal to find a female mate for a fish species that is believed to have gone extinct in the wild.
The Hawaiian silversword: another warning on climate change
(05/06/2013) The Hawaiian silversword (Argyroxyphium sandwicense), a beautiful, spiny plant from the volcanic Hawaiian highlands may not survive the ravages of climate change, according to a new study in Global Change Biology. An unmistakable plant, the silversword has long, sword-shaped leaves covered in silver hair and beautiful flowering stalks that may tower to a height of three meters.
13 year search for Taiwan's top predator comes up empty-handed
(05/01/2013) After 13 years of searching for the Formosan clouded leopard (Neofelis nebulosa brachyura), once hopeful scientists say they believe the cat is likely extinct. For more than a decade scientists set up over 1,500 camera traps and scent traps in the mountains of Taiwan where they believed the cat may still be hiding out, only to find nothing.
Rhinos now extinct in Mozambique's Limpopo National Park
(04/25/2013) Poachers have likely killed off the last rhinos in Mozambique's Limpopo National Park, according to a park official.
Featured video: time to meet The Lonely Dodo
(04/24/2013) A new short animation (see below) highlights the plight of today's most endangered species by focusing on one which is already extinct: the dodo. The animation, produced by Academy award-winning studio Aardman, introduces the world to the last, and very lonely, dodo. The short was created for conservation organization, the Durrell Wildlife Conservation Trust, which is striving to save a number of species from the dodo's fate.
Yangtze porpoise down to 1,000 animals as world's most degraded river may soon claim another extinction
(04/16/2013) A survey late last year found that the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) population has been cut in half in just six years. During a 44-day survey, experts estimated 1,000 river porpoises inhabited the river and adjoining lakes, down from around 2,000 in 2006. The ecology of China's Yangtze River has been decimated the Three Gorges Dam, ship traffic, pollution, electrofishing, and overfishing, making it arguably the world's most degraded major river. These environmental tolls have already led to the likely extinction of the Yangtze river dolphin (Lipotes vexillifer), or baiji, and possibly the Chinese paddlefish (Psephurus gladius), which is one of the world's longest freshwater fish.
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.
