Rich plant diversity leads to increased productivity, ecosystem services
(03/08/2011) A new study finds that diversity of plant species matters—big time. Analyzing nearly 600 research studies, the meta-study in the American Journal of Botany found that productivity in biodiverse plant ecosystems was 1.5 times higher than in monocultures. In other words, a prairie is more productive than a cornfield and forest more productive than a rubber plantation. The researchers warn that eroding plant diversity threatens essential ecosystems services such as food, water purification, oxygen production, carbon sequestration, and the availability of raw materials.
First large-scale map of oil palm plantations reveals big environmental toll
(03/07/2011) Expansion of industrial oil palm plantations across Malaysia and Indonesia have laid waste to vast areas of forest and peatlands, exacerbating greenhouse gas emissions and putting biodiversity at risk, reports a new satellite-based analysis that maps mature oil palm estates across Peninsular Malaysia, Borneo, and Sumatra.
Reaching kids with a conservation message via animation
(03/06/2011) During the Wildlife Conservation Network's October 2010 Wildlife Expo, mongabay.com encountered an animation that powerfully illustrates the concept of biodiversity loss in less than two-and-a-half minutes. Yesterday's Zoo recounts species that have disappeared and warns that a similar fate could befall many more unless urgent conservation action is taken. The animation is being used to raise money for wildlife protection efforts. In a March Q&A with Shane DeRolf, President & Executive Producer of Yesterday's Zoo, Mongabay learned more the project.
World's sixth mass extinction still preventable
(03/03/2011) So, here's the good news: a mass extinction, the world's sixth, is still preventable. But the bad news: if species currently threatened with extinction vanish—even over the next thousand years—homo-sapiens will be the first single species responsible for a mass extinction. Comparing today's current extinction crisis with the big five that occurred in the past, a new study in Nature finds that while the situation is dire, the choice is ultimately up to humanity. "If you look only at the critically endangered mammals—those where the risk of extinction is at least 50 percent within three of their generations—and assume that their time will run out, and they will be extinct in 1,000 years, that puts us clearly outside any range of normal, and tells us that we are moving into the mass extinction realm," explains lead author Anthony D. Barnosky, UC Berkeley professor of integrative biology.
Parks key to saving India's great mammals from extinction
(02/24/2011) Krithi Karanth grew up amid India's great mammals—literally. Daughter of conservationist and scientist Dr. Ullas Karanth, she tells mongabay.com that she saw her first wild tigers and leopard at the age of two. Yet, the India Krithi Karanth grew up in may be gone in a century, according to a massive new study by Karanth which looked at the likelihood of extinction for 25 of India's mammals, including well-known favorites like Bengal tigers and Asian elephants, along with lesser known mammals (at least outside of India) such as the nilgai and the gaur. The study found that given habitat loss over the past century, extinction stalked seven of India's mammals especially: Asiatic lions, Bengal tigers, wild dogs (also known as dholes), swamp deer, wild buffalo, Nilgiri Tahr, and the gaur. However, increasing support of protected areas and innovative conservation programs outside of parks would be key to saving India's wildlife in the 21st Century.
Top 25 most endangered turtles: Asian species in crisis
(02/23/2011) Surviving hundreds of millions of years on Earth have not saved turtles from facing extinction at human hands. A new report by the Wildlife Conservation Society (WCS) and the Turtle Conservation Coalition, identifies the world's 25 most imperiled turtles, including one that is practically assured extinction: 'Lonesome George' the last Abdington Island tortoise in the world. The list includes four turtle species from South and Central America, three from Africa, and one from Australia. But Asia is the hotbed for turtles in trouble with 17 of the top 25 species, or 68%. The numbers are even more alarming if one looks only at the top ten: eight of the top ten are in Asia, and six of these in China.
Rehabilitated orangutans need guards in Borneo, says activist
(02/19/2011) 1,200 orangutans set for reintroduction into the wild in Indonesian Borneo will be immediately at risk from poaching and illegal logging, warned an orangutan welfare group.
Worldwide search for 'lost frogs' ends with 4% success, but some surprises
(02/16/2011) Last August, a group of conservation agencies launched the Search for Lost Frogs, which employed 126 researchers to scour 21 countries for 100 amphibian species, some of which have not been seen for decades. After five months, expeditions found 4 amphibians out of the 100 targets, highlighting the likelihood that most of the remaining species are in fact extinct; however the global expedition also uncovered some happy surprises. Amphibians have been devastated over the last few decades; highly sensitive to environmental impacts, species have been hard hit by deforestation, habitat loss, pollution, agricultural chemicals, overexploitation for food, climate change, and a devastating fungal disease, chytridiomycosis. Researchers say that in the past 30 years, its likely 120 amphibians have been lost forever.
Selling the Forests that Saved Britain
(02/15/2011) I confess that British Prime Minister David Cameron’s proposal to auction off all 650,000 acres of England’s national forests to the highest bidder came as a bit of a shock to me – especially as the contained such world-famous national treasures as Robin Hood’s Sherwood Forest, the Forest of Dean and the New Forest. Although warned by my Irish mother that Tories can never be trusted, Mr. Cameron’s passionate pledge to deliver the “greenest government ever” seemed sincere, especially given his ambitious plans to cut Britain’s pollution. Anyway, even if he turned out to be as slippery as his predecessors, his deep green Liberal Democratic coalition partners would, I thought, keep the planet high on his priority list.
Cambodia approves titanium mine in world's 'most threatened forest'
(02/15/2011) The Cambodian government has approved a mine that environmentalists and locals fear will harm wildlife, pollute rivers, and put an end to a burgeoning ecotourism in one of the last pristine areas of what Conservation International (CI) recently dubbed 'the world's most threatened forest'. Prime Minister, Hun Sen, approved the mine concession to the United Khmer Group, granting them 20,400 hectares for strip mining in Cambodia's Cardamom Mountains. The biodiverse, relatively intact forests of the Cardamom Mountains are a part of the Indo-Burma forest hotspot of Southeast Asia, which CI put at the top of their list of the world's most threatened forests. With only 5% of habitat remaining, the forest was found to be more imperiled than the Amazon, the Congo, and even the forests of Indonesia and Malaysia.
India pledges to protect cat-crazy rainforest
(02/14/2011) The Jeypore-Dehing lowland rainforest in Assam, India is home to a record seven wild cat species, more than any other ecosystem on Earth. While it took wildlife biologist Kashmira Kakati two years of camera-trapping to document the seven felines, the announcement put this forest on the map—and may very well save it. A year after the record was announced, officials are promising to pursue permanent preservation status for the forest, which is threatened by logging, poaching, oil and coal industries, and big hydroelectric projects.
Not enough data on world's tropical plants to predict impact of warming world
(02/14/2011) How many tropical plant species are threatened by climate change? Which plants have big enough ranges to survive a warming world, not to mention deforestation? How likely is it that the tropics are undergoing a current mass extinction? These questions may appear straight forward, but a new study in Global Change Biology finds that researchers lack the hard data necessary to come to any confident conclusions. According to the study, nine out of ten tropical plants from Africa, Asia, and South America lack the minimum number of collections needed (at least 20) to determine the species' range, and therefore predict the impact of climate change.
Vines rising in the Amazon and other American rainforests
(02/14/2011) For years tropical scientists have anecdotally reported an increase in vines in the Amazon and other American tropical forests, but now a number of studies have confirmed such reports: vines are on the rise in Neotropical rainforests.
As South Sudan eyes independence, will it choose choose to protect its wildlife?
(02/11/2011) After the people of South Sudan have voted overwhelmingly for independence, the work of building a nation begins. Set to become the world's newest country on July 9th of this year, one of many tasks facing the nation's nascent leaders is the conservation of its stunning wildlife. In 2007, following two decades of brutal civil war, the Wildlife Conservation Society (WCS) surveyed South Sudan. What they found surprised everyone: 1.3 million white-eared kob, tiang (or topi) antelope and Mongalla gazelle still roamed the plains, making up the world's second largest migration after the Serengeti. The civil war had not, as expected, largely diminished the Sudan's great wildernesses, which are also inhabited by buffalo, giraffe, lion, bongo, chimpanzee, and some 8,000 elephants. However, with new nationhood comes tough decisions and new pressures. Multi-national companies seeking to exploit the nation's vast natural resources are expected to arrive in South Sudan, tempting them with promises of development and economic growth, promises that have proven uneven at best across Africa.
The ocean crisis: hope in troubled waters, an interview with Carl Safina
(02/07/2011) Being compared—by more than one reviewer—to Henry Thoreau and Rachel Carson would make any nature writer's day. But add in effusive reviews that compare one to a jazz musician, Ernest Hemingway, and Charles Darwin, and you have a sense of the praise heaped on Carl Safina for his newest work, The View from Lazy Point: A Natural Year in an Unnatural World. Like Safina's other books, The View from Lazy Point focuses on the beauty, poetry, and crisis of the world's oceans and its hundreds-of-thousands of unique inhabitants. Taking the reader on a journey around the world—the Arctic, Antarctic, and the tropics—Safina always returns home to take in the view, and write about the wildlife of his home, i.e. Lazy Point, on Long Island. While Safina's newest book addresses the many ways in which the ocean is being degraded, depleted, and ultimately imperiled as a living ecosystem (such as overfishing and climate change) it also tweezes out stories of hope by focusing on how single animals survive, and in turn how nature survives in an increasingly human world. However, what makes Safina's work different than most nature writing is his ability to move seamlessly from contemporary practical problems to the age-old philosophical underpinnings that got us here. By doing so, he points a way forward.
Paradise & Paradox: a semester in Ecuador
(02/02/2011) A semester abroad is an opportunity to live a sort of compacted life. In a few short months you seem to gain the experience of a much longer time and make enough memories to fill years. I recall a weeklong trip to the Alvord Desert with a field biology class from Portland Community College: the adventure of living out of a van, conducting research, and experiencing a place with classmates turned colleagues and professors turned friends who knew the desert like the backs of their hands. In that regard, it had a lot in common with my semester in Ecuador, but I can't think of anything that could have prepared me for a four month stay in a small South American country that I knew very little about.
From Cambodia to California: the world's top 10 most threatened forests
(02/02/2011) Growing populations, expanding agriculture, commodities such as palm oil and paper, logging, urban sprawl, mining, and other human impacts have pushed many of the world's great forests to the brink. Yet scientists, environmentalists, and even some policymakers increasingly warn that forests are worth more standing than felled. They argue that by safeguarding vulnerable biodiversity, sequestering carbon, controlling erosion, and providing fresh water, forests provide services to humanity, not to mention the unquantifiable importance of having wild places in an increasingly human-modified world. Still, the decline of the world's forests continues: the FAO estimating that around 10 million hectares of tropical forest are lost every year. Of course, some of these forests are more imperiled than others, and a new analysis by Conservation International (CI) has catalogued the world's 10 most threatened forests.
Malaysian palm oil producers destroying Borneo peat forests faster than ever before
(02/01/2011) Peatlands and rainforests in Malaysia's Sarawak state on the island of Borneo are being rapidly destroyed for oil palm plantations, according to new studies by environmental group Wetlands International and remote sensing institute Sarvision. The analysis shows that more than one third (353,000 hectares or 872,000 acres) of Sarawak's peatswamp forests and ten percent of the state's rainforests were cleared between 2005 and 2010. About 65 percent of the area was converted for oil palm, which is replacing logging as timber stocks have been exhausted by unsustainable harvesting practices.
Scientists to document impact of converting rainforest into oil palm plantations
(01/30/2011) Scientists have partnered with one of the world's largest palm oil producers to measure the impact of converting tropical forest into an oil palm plantation, reports Nature News.
Africa's vanishing wild: mammal populations cut in half
(01/27/2011) The big mammals for which Africa is so famous are vanishing in staggering numbers. According to a study published last year: Africa's large mammal populations have dropped by 59% in just 40 years. But what is even more alarming was that the study only looked at mammal populations residing in parks and wildlife areas, i.e. lands that are, at least on paper, under governmental protection. Surveying 78 protected areas for 69 species, the study included global favorites such as the African elephant, giraffes, zebra, wildebeest, and even Africa's feline king, the lion. "We weren’t surprised that populations had dropped but we were surprised by how large the drops had been," lead author Ian Craigie told mongabay.com in an interview.
Greening the world with palm oil?
(01/26/2011) The commercial shows a typical office setting. A worker sits drearily at a desk, shredding papers and watching minutes tick by on the clock. When his break comes, he takes out a Nestle KitKat bar. As he tears into the package, the viewer, but not the office worker, notices something is amiss—what should be chocolate has been replaced by the dark hairy finger of an orangutan. With the jarring crunch of teeth breaking through bone, the worker bites into the 'bar'. Drops of blood fall on the keyboard and run down his face. His officemates stare, horrified. The advertisement cuts to a solitary tree standing amid a deforested landscape. A chainsaw whines. The message: Palm oil—an ingredient in many Nestle products—is killing orangutans by destroying their habitat, the rainforests of Borneo and Sumatra.
95% of Liberia's elephants killed by poachers
(01/24/2011) Since the 1980s, Liberia has lost 19,000 elephants to illegal poaching, according to Patrick Omondi of the Kenya Wildlife Service speaking in Monrovia, the capital of Liberia. The poaching of Liberia's elephants has cut the population by 95% leaving only 1,000 elephants remaining.
Can entrepreneurial insights save the Masai Mara?
(01/23/2011) At the epicenter of East Africa’s Great Migration, the Masai Mara of Southern Kenya hosts one of the world's great wildlife spectacles, as herds of over two million wildebeest, zebra, and gazelle congregate in search of fresh grazing brought by the annual rains. Yet, even here in one of the world's great wild places, modern man casts a long shadow, and the Mara Ecosystem is degenerating under the pressures of uncontrolled tourism, divisive local politics, and the burgeoning population growth of the local Maasai people. Working to reverse what seems to many conservationists a hopeless trend for the area, a champion of the Masai Mara has emerged in AJ Patel, founder of the Hasla Mara Wildlife Conservation Foundation. Building a career as a successful entrepreneur and civic leader in San Francisco Bay Area's Silicon Valley, AJ now focuses his considerable business experience and skills for the cause of global wildlife conservation
New hope for rare lemurs in Madagascar
(01/20/2011) A survey of a remote forest area in Madagascar turned up seven new groups of silky sifaka, a critically endangered lemur threatened by habitat destruction. The finding raises hope that the species—which is listed as one of the world's 25 most endangered primates—is surviving in Marojejy National Park despite an outbreak of illegal rosewood logging in 2009 and 2010.
American cougars on the decline: 'We’re running against the clock,' says big cat expert
(01/17/2011) It holds the Guinness World Record for having the most names of any animal on the planet, with 40 in English alone. It's also the widest-ranging native land animal in the Americas, yet is declining throughout much of its range. Mongabay talks with big cat expert Dr. Howard Quigley about the status and research implications of the elusive, enigmatic, and unique cougar.
Picture: rare cat photographed in Borneo not believed to be extinct
(01/15/2011) Camera traps have photographed a rare small cat species in Borneo, but contrary to claims in The Telegragh, which reported on the story, the Bornean bay cat was not believed to be extinct, only rare.
Pictures: 6 'lost' frog species discovered in Haiti
(01/12/2011) On the eve of the anniversary of last year's destructive earthquake, scientists have announced a bit of positive news out of Haiti: the rediscovery of six species of frogs.
With REDD, could financial markets become species' extinction risk?
(01/06/2011) The emergence of a Reducing Emissions from Deforestation and Degradation (REDD) mechanism for protecting forests could introduce new risks for biodiversity by linking conservation finance to exotic financial derivatives, warn researchers writing in the journal Conservation Letters. Jacob Phelps, Edward L. Webb, and Lian P. Koh argue that REDD could effectively link the fate of some species to the short-term whims of the carbon market. Conservation projects funded primarily by REDD are most at risk of being undermined by declining in carbon prices or changing investor preference. The authors add that the short-term nature of REDD—which is seen as a stop gap measure of at most 30 years—may fail deliver benefits over the time-scale need to safeguard biodiversity.
Top 10 Environmental Stories of 2010
(12/20/2010) Below is a quick review of some of the biggest environmental stories of 2010: Climate change rears it ugly head; Oil spill in the Gulf; Agreement to save global biodiversity; Illegal logging crisis in Madagascar; REDD kicks off in Indonesia; Brazil deforestation falls to its lowest level; Hungary's red sludge; Nestle caves to social media activists; New mammals galore' and Global climate framework back on the table?
Biodiversity and slash-and-burn agriculture in Papua New Guinea
(12/20/2010) As pressures increase on the rich forests of Papua New Guinea, how will biodiversity fare? A new study in mongabay.com's Tropical Conservation Science attempts to answer this question by looking at how bird species are impacted by slash-and-burn agriculture. While locals have been practicing such agriculture for 5,000 years, rising populations and societal changes are expected to increase the pressure of slash-and-burn agriculture on forests and the species that live there.
Teaching orangutans to be wild – orangutan rehabilitation
(12/15/2010) Michelle Desilets, Executive Director of the Orangutan Land Trust, spoke with Laurel Neme on her 'The WildLife' radio show and podcast about the process of rehabilitating orphaned orangutans and teaching them to be wild. This is the second in a two-part interview. The first part covered orangutan biology, habits and the interconnected threats, from the pet trade to habitat loss and expansion of oil palm plantations, facing these creatures. This second part focuses on what happens to surviving orangutans.
Primatologists: the best hope for apes is the best hope for us
(12/15/2010) Distinguished conservation luminaries, eminent primate experts, ape-suited bucket wielders, a group of African drummers and nearly 1,500 people gathered in London last week for an evening of talks to shine the spotlight on the plight of apes and the forests in which they live, sending a strong message to the climate negotiators hammering out a REDD+ mechanism in Cancun. Hosted by conservation heavyweight Sir David Attenborough, Hope 4 Apes was something of a reunion of the first Hope 4 Apes event that took place ten years ago to raise awareness of -- and funding for -- ape conservation.
Picture: New lemur in Madagascar
(12/15/2010) Researchers have discovered a new species of lemur in Madagascar.
The secrets of animal TV: many nature shows rely on unethical tactics
(12/14/2010) Classic animal series like Shark Week hosted by the Discovery Channel and Wild America by Marty Stouffer have captivated audiences for years, bringing them closer than ever to nature from the comfort of their living room. Unfortunately what the audience doesn’t know is that many of those wildlife films incorporate unethical behavior including animal harassment, staged scenes, and the use of trained animals. These claims come from Chris Palmer, a veteran wildlife filmmaker with over 300 hours of original programming for prime time television and the giant screen, director of the Center for Environmental Filmmaking at American University and author of Shooting in the Wild: An Insider’s Account of Making Movies in the Animal Kingdom (Sierra Club Books, 2010). Palmer concedes that his films have used these unethical techniques and that significant proportion of the wildlife programming we find ourselves enthralled with is as fake and scripted as any Hollywood movie.
The problem-solving ape: what makes orangutans special and why they are threatened
(12/13/2010) Michelle Desilets, Executive Director of the Orangutan Land Trust, spoke with Laurel Neme on her “The WildLife” radio show and podcast about orangutans. In the first part of her interview, they discussed orangutan biology, habits and the interconnected threats, from the pet trade to habitat loss and expansion of oil palm plantations, facing these creatures. The second part covers the process of rehabilitating orangutans and teaching them to be wild.
Sulawesi groups recognized for efforts to save endangered wildlife, forests
(12/08/2010) Two groups working with local communities to conserve forests in Sulawesi have won mongabay.com's 2010 Conservation Award. The Alliance for Tompotika Conservation (AlTo), which works in Central Sulawesi, and the Nantu Forest Conservation Program, which operates in North Sulawesi, were recognized for their efforts to protect endangered forests on the Indonesian island, which is known for its high levels of endemic species.
Saving Sulawesi's 'pig-deer', the babirusa
(12/06/2010) The babirusa of Sulawesi may be one of the world's oddest looking—and acting—mammals. Literally meaning 'pig-deer' the babirusa, which includes four species, belongs to its own genus 'Babyrousa' in the pig family. Males are especially unique, sporting four tusks, two of which appear to come right out of the animal's snout. To make it to the top of the babirusa hierarchy, males will combat each other in an activity dubbed 'boxing' where they will rear up on their hind legs and club at each other. Despite their many oddities, the babriusa were not formally studied until the late 1980s when Dr. Lynn Clayton spent four years in Sulawesi's forest observing them.
'Environmental and social aggression': oil exploration threatens award-winning marine protected area
(12/01/2010) The Seaflower Marine Protected Area (MPA), which recently won top honors at the Convention on Biological Diversity (CBD) in Japan, is now under threat by planned oil exploration in the region, according to the Providence Foundation which is devoted to protecting the area. Proposed blocs for exploration by the Colombian government lie in the North Cays adjacent to the park, and perhaps even inside MPA boundaries. Spreading over 65,000 square kilometers (6.5 million hectares), Seaflower MPA lies within the Colombian Caribbean department known as the Archipelago of San Andres, Old Providence and Santa Catalina. This richly diverse Archipelago is home to a known 57 coral species, over 400 fish, and some 150 birds, as well as the ethnic and cultural minority: the Raizal people. The prospect of massive infrastructure or, even worse, oil spills in the area could devastate the park and locals' livelihoods.
Study: REDD could save species from extinction, if well-funded
(12/01/2010) The burgeoning global program REDD+ (Reduced Emissions from Deforestation and Forest Degradation) could do more than mitigate climate change, according to a new study in Conservation Letters by scientists with Conservation International (CI). Analyzing a sample of 2,500 forest animals, including mammals, birds and amphibians, researchers found that REDD+ could reduce the rate of extinction among these species by 46-82% over five years. The wide range in the study's findings depends on the amount of funds devoted to REDD+: more funds means greater forest preservation and, thereby, less extinction.
Earth could see 4 degrees Celsius warming in less than a lifetime
(11/29/2010) By the time children born this year reach 50 years old, the Earth could be 4 degrees Celsius warmer (7.2 degrees Fahrenheit) warns a new study as governments meet in Cancun for this year's UN climate summit, which is not expected to produce an agreement. Last year governments pledged in the non-binding Copenhagen Accord to keep temperatures below a 2 degree Celsius rise, but a new study in Philosophical Transactions of the Royal Society A argues that even with current promises to cut emissions this is unlikely and, in a worst-case scenario, a rise of 4 degrees Celsius is possible by 2060.
Ad warning of mass extinction appears in Times Square
(11/24/2010) An advertisement warning holiday pedestrians about mass extinction—and asking for their help—first appeared in Times Square this week. The ad which flashes on CBS's Super LED Screen between 7th and 8th avenues was created by US conservation organization, the Center for Biological Diversity.
Oil, indigenous people, and Ecuador's big idea
(11/23/2010) Ecuador's big idea—potentially Earth-rattling—goes something like this: the international community pays the small South American nation not to drill for nearly a billion barrels of oil in a massive block of Yasuni National Park. While Ecuador receives hundred of millions in an UN-backed fund, what does the international community receive? Arguably the world's most biodiverse rainforest is saved from oil extraction, two indigenous tribes' requests to be left uncontacted are respected, and some 400 million metric tons of CO2 is not emitted from burning the oil. In other words, the international community is being asked to put money where its mouth is on climate change, indigenous rights, and biodiversity loss. David Romo Vallejo, professor at the University of San Francisco Quito and co-director of Tiputini research station in Yasuni, recently told mongabay.com in an interview that this is "the best proposal so far made to ensure the protection of this incredible site."
Scientists call upon Indonesia to recognize value of secondary forests
(11/18/2010) A group of scientists have called upon the governments of Indonesia and Norway to recognize the conservation value of logged-over and "degraded" forests under their partnership on reducing emissions from deforestation and degradation. The letter urges the Indonesian government to extend protection to forest areas that may not be pristine but still serve as important carbon sinks, house endangered wildlife, and provide livelihoods for communities.
Reforestation effort launched in Borneo with nearly-extinct rhinos in mind
(11/18/2010) The Rhino and Forest Fund (RFF) has partnered with the Forestry Department of Sabah in northern Borneo to launch a long-term reforestation project to aid Malaysia's threatened species with particular emphasis on the Bornean rhino (Dicerorhinus sumatrensis harrissoni), one of the world's most imperiled big mammals. The reforestation project will be occurring in and adjacent to Tabin Wildlife Reserve, which is surrounded on all sides by oil palm plantations.
Pictures: 'Mr. Burns' frog discovered in Colombia along with 2 other new species
(11/15/2010) Three previously undocumented species of frog have been discovered in Colombia, reports Conservation International.
Chaco biodiversity expedition suspended
(11/15/2010) A joint expedition by the Natural History Museum (NHM), London and the Natural History Museum, Asuncion to the dwindling dry forest of the Gran Chaco in Paraguay to record biodiversity, and hopefully uncover 'hundreds' of new species, has been suspended by the Paraguayan government. The suspension comes after a local organization voiced concern that the expedition would threaten uncontacted member of the Ayoreo tribe in the forest.
What do wolves and sharks have in common?
(11/15/2010) Sharks dwell in the ocean, wolves on land; sharks are a type of fish, wolves are a mammal; sharks go back some 400 million years, wolves only some 2 million years. So, these animals should have little in common, right? However, a new study in Frontiers in Ecology and the Environment points to surprising similarities among these disparate animals. As top predators, both wolves and sharks impact their prey and other species in similar ways.
Critics say Obama slow on endangered species
(11/15/2010) The Obama Administration is lagging behind past administrations in its listing of dwindling species under the Endangered Species Act (ESA). To date the US Fish and Wildlife Service has added 51 species to the ESA since Obama's took office, according to the conservation group, Center for Biological Diversity. By contrast, the Clinton Administration averaged 65 species a year with a total of 522 species protected. Obama is more proactive than George W. Bush, however, who was seen by many critics as actively undercutting the ESA. Only one of the species protected so far by the Obama Administration is found in the continental US.
Cheetahs reproduce more successfully after early pregnancies
(11/15/2010) Early pregnancies prepare a cheetah for a life of productive motherhood, new research shows. A study published on 20 September in Conservation Letters advises captive breeding programs to focus on breeding female cheetahs at young ages to set the stage for many litters throughout their lives. The world's fastest animal, the cheetah has not outpaced a disheartening march toward extinction. Populations have declined from an estimated 100,000 a century ago to about 13,000 today. For years, researchers have pointed to the high genetic similarities among individual cheetahs as the main reason why captive cheetahs don't often get pregnant.
Rainforests, wildlife preserved by indigenous spiritual beliefs
(11/15/2010) New research within the native Wapishana and Makushi communities of Guyana suggests that indigenous cultural beliefs such as shamanism help preserve tropical forests and wildlife. The analysis, published in the September 2010 Journal of Latin American Geography, draws from a massive data set that tracks wildlife populations, hunting kill sites, and spiritually significant features of the landscape within a 48,000-square-kilometer area in southern Guyana. The authors recruited the hunters themselves to record much of the data.
