Elephants: the gardeners of Asia's and Africa's forests
(04/25/2011) It seems difficult to imagine elephants delicately tending a garden, but these pachyderms may well be the world's weightiest horticulturalist. Elephants both in Asia and Africa eat abundant amounts of fruit when available; seeds pass through their guts, and after expelled—sometimes tens of miles down the trail—sprouts a new plant if conditions are right. This process is known by ecologists as 'seed dispersal', and scientists have long studied the 'gardening' capacities of monkeys, birds, bats, and rodents. Recently, however, researchers have begun to document the seed dispersal capacity of the world's largest land animal, the elephant, proving that this species may be among the world's most important tropical gardeners.
What does Nature give us? A special Earth Day article
(04/22/2011) There is no question that Earth has been a giving planet. Everything humans have needed to survive, and thrive, was provided by the natural world around us: food, water, medicine, materials for shelter, and even natural cycles such as climate and nutrients. Scientists have come to term such gifts 'ecosystem services', however the recognition of such services goes back thousands of years, and perhaps even farther if one accepts the caves paintings at Lascaux as evidence. Yet we have so disconnected ourselves from the natural world that it is easy—and often convenient—to forget that nature remains as giving as ever, even as it vanishes bit-by-bit. The rise of technology and industry may have distanced us superficially from nature, but it has not changed our reliance on the natural world: most of what we use and consume on a daily basis remains the product of multitudes of interactions within nature, and many of those interactions are imperiled. Beyond such physical goods, the natural world provides less tangible, but just as important, gifts in terms of beauty, art, and spirituality.
Warmer temperatures may be exterminating pika populations one-by-one
(04/21/2011) The last decade has not been a good one for the American pika (Ochotona princeps) according to a new study in Global Change Biology. Over the past ten years extinction rates have increased by nearly five times for pika populations in the Great Basin region of the US. Examining extinctions of pike populations in the region over the past 110 years, researchers found that nearly half of the extinction events occurred since 1999.
Scientists follow rise of mercury pollution in seabird feathers
(04/18/2011) Analyzing the feathers of the black-footed albatross (Phoebastria nigripes) going back to 1880. researchers have uncovered rising levels of the toxic methylmercury in the endangered birds that is generally consistent with rising mercury emissions in the Pacific region. Methylmercury is a more toxic compound than mercury that binds with organic molecules when it is released through industrial processes, such as burning coal and other fossil fuels.
The great penguin rescue: far-flung community cooperates, sacrifices to save 4,000 penguins from oil spill
(04/18/2011) One of the world remotest communities, the UK's Tristan da Cunha archipelago, has come together to save 4,000 endangered penguins following a devastating oil spill, reports the Guardian. Last month a freighter ran aground on Nightingale Island releasing 1,500 tons of oil, potentially devastating the local population of northern rockhopper penguins (Eudyptes moseleyi), which are listed as Endangered by the IUCN Red List. However, fortunately for the penguins, the tiny community of 260 people living on the Tristan da Cunha archipelago were unwilling to give up on the oiled birds.
US wolves lose to politics
(04/17/2011) A 'rider' attached to the most recent budget passed this week in the US congress has stripped gray wolves from the protection of the Endangered Species Act, a first in the law's nearly 40-year-history. The rider, which was signed into law under the budget on Friday by US President Barack Obama, hands gray wolves (Canis lupus) in Montana, Idaho, Utah, Washington, and Oregon from Federal protection to state control. Hunting is expected to begin soon.
Vietnam creates reserve for newly-discovered, nearly-extinct mammal, the saola
(04/14/2011) The Vietnam government and local people have approved a Saola Natural Reserve to protect one of the world's most endangered—and most elusive—mammals. Only discovered by the outside world in 1992, the saola (Pseudoryx nghetinhensis) inhabits the lush forests of the Annamite Mountains. No one knows how many saola remain, but it has been classified as Critically Endangered as it is likely very few. Recently, conservationist William Robichaud told mongabay.com that the saola was "perhaps the most spectacular zoological discovery of the 20th century", comparing it only to the discovery of the okapi in central Africa in 1900.
From the Serengeti to Lake Natron: is the Tanzanian government aiming to destroy its wildlife and lands?
(04/14/2011) What's happening in Tanzania? This is a question making the rounds in conservation and environmental circles. Why is a nation that has so much invested in its wild lands and wild animals willing to pursue projects that appear destined not only to wreak havoc on the East African nation's world-famous wildlife and ecosystems, but to cripple its economically-important tourism industry? The most well known example is the proposed road bisecting Serengeti National Park, which scientists, conservationists, the UN, and foreign governments alike have condemned. But there are other concerns among conservationists, including the fast-tracking of soda ash mining in East Africa's most important breeding ground for millions of lesser flamingo, and the recent announcement to nullify an application for UNESCO Heritage Status for a portion of Tanzania's Eastern Arc Mountains, a threatened forest rich in species found no-where else. According to President Jakaya Kikwete, Tanzania is simply trying to provide for its poorest citizens (such as communities near the Serengeti and the Eastern Arc Mountains) while pursuing western-style industrial development.
Opposition rises against Mekong dam as governments ponder decision
(04/13/2011) As the governments of Laos, Thailand, Cambodia, and Vietnam ready to meet on April 19th to decide whether or not to move forward on the Xayaburi Dam, critics of Mekong River hydroelectric project have warned that the dam will devastate freshwater biodiversity and impact the livelihoods of hundreds of thousands, if not more. Last month a coalition of 263 organizations from 51 countries released a letter in opposition of the dam’s construction.
Noise in oceans leads to 'severe acoustic trauma' in octopus, squid
(04/12/2011) Researchers have documented for years how noise pollution impacts dolphins in whales, but a new study in Frontiers in Ecology and the Environment finds that even low intensity noise can severely injure cephalopods, which include octopus, squid, and cuttlefish. The injuries are bad enough to possibly lead to stranding and death, thereby providing a feasible explanation for a number of recent strandings, including giant squid washing ashore in Spain.
Giant fish help grow the Amazon rainforest
(04/12/2011) A fruit in the flooded Amazon falls from a tree and plops in the water. Before it can even sink to the floor, a 60-pound monster fish with a voracious appetite gobbles it. Nearly a week later—and miles away—the fish expels its waste, including seeds from the fruit eaten long ago and far away. One fortunate seed floats to a particularly suitable spot and germinates. Many years later the new fruit tree is thriving, while the same monster-fish returns from time-to-time, waiting for another meal to drop from the sky. This process is known as seed-dispersal, and while researchers have studied the seed-dispersal capacity of such species as birds, bats, monkeys, and rodents, one type of animal is often overlooked: fish.
Antarctic penguins losing to climate change through 80% krill decline
(04/11/2011) Climate change has hit species of Antarctic penguins by causing a staggering decline in their prey: krill. A new study in the Proceedings of the National Academy of Sciences (PNAS) has found that both chinstrap penguins (Pygoscelis antarcticus) and Adélie penguins (Pygoscelis adeliae) have seen their populations decline likely do to less krill, instead of habitat changes. Since 1970 krill populations have fallen by 80% in the Southern Ocean surrounding Antarctica. Because krill require sea ice to reproduce, shrinking sea ice from climate change has made it more difficult for them to breed.
Customs officials confiscate over a thousand monitor lizards headed to China
(04/11/2011) Thai Customs officials have confiscated 1,800 Bengal monitor lizards on the border between Thailand and Malaysia, reports the AFP. Officials said the lizards were likely headed to China for consumption.
A new rhino species?
(04/11/2011) Using genetic data and re-assessing physical evidence, scientists write that they have uncovered a new species of rhino, long considered by biologists as merely a subspecies. Researchers write in an open access PLoS ONE paper published last year that evidence has shown the northern white rhino is in fact a distinct species from the more commonly known—and far more common—southern white rhino. If the scientific community accepts the paper's argument it could impact northern white rhino conservation, as the species would overnight become the world's most endangered rhino species with likely less than ten surviving.
Cambodian prime minister cancels titanium mine project citing impact on biodiversity and local people
(04/11/2011) In a surprise move, the Cambodian Prime Minister, Sandech Hun Sen, has cancelled a titanium strip mine project in one of Southeast Asia’s last great intact forest ecosystems, the Cardamom Mountains. According to a press release sent out by the Cambodian government the mine was canceled due to "concerns of the impact on the environment, biodiversity and local livelihoods" of villagers. The mine, which was planned to sit directly in the migration route for the largest population of Asian elephants in Cambodia, had been largely opposed by locals in the region who spent years developing eco-tourism in the region.
New method to measure threat of extinction could help conservationists prioritize
(04/07/2011) Researchers have developed a new method to predict how close species are to extinction. Dubbed SAFE (Species Ability to Forestall Extinction) the researchers believe the new tool, published in the Frontiers in Ecology and Environment, should help conservationists select which species to focus on saving and which, perhaps controversially, should be let go.
The value of the little guy, an interview with Tyler Prize-winning entomologist May Berenbaum
(04/06/2011) May Berenbaum knows a thing or two about insects: in recognition of her lifelong work on the interactions between insects and plants, she has had a character on The X-Files named after her, received the Public Understanding of Science and Technology Award for her work in making science accessible to the public, and this year has been awarded the prestigious Tyler Environmental Prize. "Winning the Tyler Prize is an incredible honor—most of my scientific heroes have been Tyler Prize winners and I’m exceedingly grateful to be considered worthy of being included among their ranks," Berenbaum told mongabay.com in an interview. "The Prize is also tremendously enabling—because the money is unrestricted I can use it to carry out projects that have been difficult to fund."
Iconic cheetah, Chewbaaka, dies
(04/05/2011) The symbol of the Cheetah Conservation Fund (CCF), a male cheetah named Chewbaaka has passed away. At the age of 16, Chewbaaka outlived most cheetahs in the wild, but was killed from wounds suffered after a rabid kudu leapt into his enclosure.
The saola: rushing to save the most 'spectacular zoological discovery' of the 20th Century
(04/04/2011) The saola (Pseudoryx nghetinhensis) may be the most enigmatic, beautiful, and endangered big mammal in the world—that no one has ever heard of. The shy ungulate looks like an African antelope—perhaps inhabiting the wide deserts of the Sahara—but instead it lives in the dense jungles of Vietnam and Laos, and is more related to wild cattle than Africa's antelopes. The saola is so unusual that is has been given its own genus: Pseudoryx, due to its superficial similarities to Africa's oryx. In the company of humans this quiet forest dweller acts calm and tame, but has yet to survive captivity long. Yet strangest of all, the 200 pound (90 kilogram) animal remained wholly unknown to science until 1992.
Bats worth billions
(04/03/2011) US agriculture stands to lose billions in free ecosystem services from the often-feared and rarely respected humble bat. According to a recent study in Science bats in North America provide the US agricultural industry at least $3.7 billion and up to a staggering $53 billion a year by eating mounds of potentially pesky insects. Yet these bats, and their economic services, are under threat by a perplexing disease known as white-nose syndrome (WNS) and to a lesser extent wind turbines.
Photo: new vipers discovered in Asia's rainforests
(03/30/2011) Researchers have discovered two new species of pitviper in Southeast Asia. After collecting snakes throughout the Asian tropics—Thailand, Laos, Vietnam, and Cambodia—researchers were able to parse out a more complex set of species than had been recognized. One of the new vipers has been dubbed Cryptelytrops rubeus for its ruby-colored eyes.
What's behind the 85% decline of mammals in West Africa's parks?
(03/28/2011) A recent, well-covered study found that African mammals populations are in steep decline in the continent's protected areas. Large mammal populations over forty years have dropped by 59% on average in Africa [read an interview on the study here] and by 85% in west and central Africa, according to the study headed by Ian Craigie, which links the decline to continuing habitat degradation as well as hunting and human-wildlife conflict. However, a new opinion piece in mongabay.com's open access journal Tropical Conservation Science argues that this study missed an important factor in central and west Africa where the decline in mammals was the worst: rainfall.
India says tiger numbers up, but expert raises doubts
(03/28/2011) According to the Indian government tigers have gone up by 225 individuals in the past four years, from 1,411 big cats to 1,636 today, a 16% increase. The new census, however, also counts 70 tigers in the Sundarbans, which were not included in the past census, making the new grand total 1,706 Bengal tigers (Panthera tigris tigris). But don't raise champagne glasses just yet, renowned conservationist with Wildlife Conservation Society (WCS) and tiger expert, Dr. Ullas Karanth, sees serious issues with the new tally, including a methodology that "has not been made public in a scientifically acceptable manner" and depends on a big count every few years instead of comprehensive and reliable year-by-year tracking methods. Despite such doubts, the news has generally been greeted with accolades.
New land snail invading Singapore requires swift action
(03/28/2011) An African land snail Limicolaria flammea has been discovered by researchers in six locations in Singapore, perhaps heralding a new invasion of alien land snails in Southeast Asia. Although snails may seem largely innocuous creatures, past invasions have resulted in agricultural and economic damage. The global invasion of the giant African land snail (Achatina fulica) has been called one of the world's top 100 worst alien species. Writing in mongabay.com's open access journal Tropical Conservation Science, researchers examine the issue and provide suggestions as to how Singapore authorities can quickly rid the nation of Limicolaria flammea.
How to save the Pantanal and increase profits for the cattle industry
(03/28/2011) The Pantanal spanning Brazil, Bolivia, and Paraguay is the world's largest wetland—the size of Florida—and home to a wide-variety of charismatic species, such as jaguars, capybaras, and giant anteaters. However, the great wetland is threatened by expansion in big agriculture and an increasingly intensive cattle industry. Yet there is hope: a new study by Wildlife Conservation Society of Brazil (WCS-Brazil) researchers has found that cattle and the ecosystem can exist harmoniously. By replacing current practices with rotational grazing, cattle ranchers gain a healthier herd and more profits while safeguarding the ecological integrity and wildlife of the world's largest wetland system. The study published in mongabay.com's open access journal Tropical Conservation Science is a rare instance of a win-win situation.
Counting orangutans: the best way to survey the great apes
(03/28/2011) How do you count orangutans when they are difficult to spot in the wild given that they are shy, arboreal, and few and far between? To find a solution, biologists have turned to estimating orangutan populations by counting their nests, which the great apes make anew every night. In order to make the most accurate count possible, researchers have studied the different factors that could impact the success, or lack thereof, of nest-counters in mongabay.com's open access journal Tropical Conservation Science.
Cloud forest dung beetles in India point to 'fossil ecosystem'
(03/28/2011) In the cloud forests and grasslands of India's Western Ghats, known as sholas, researchers have for the first time comprehensively studied the inhabiting dung beetle populations. The resulting study in mongabay.com's open access journal Tropical Conservation Science, has led scientists to hypothesize that the beetles in concordance with the sheep-like mammal, the nilgiri tahr (Nilgiritragus hylocrius), may be a sign of a 'fossil ecosystem'.
Expedition granted?: hoping to save nearly-extinct seals through National Geographic contest
(03/24/2011) Dashiell Masland, known as 'Dash', has always been in love with the sea and its inhabitants. Now, she is hoping to take that passion to the Hawaiian Islands to save one of the world's most threatened marine mammals: the Hawaiian monk seals (Monachus schauinslandi). Extinction is a real possibility: already, the related Carribbean monk seal vanished forever around 1950. Decimated by sealers, whalers, and even soldiers in World War II, the Hawaiian monk seals are struggling to make a come back with only 1,100 individuals surviving and the population decreasing by 4% a year. Today many face starvation due to a lack of prey. This is where Masland, who is currently competing in National Geographic's Expedition Granted, hopes to help.
New seabird discovered, first in 55 years
(03/23/2011) Stephen Maturin, if he were not fictional, would be delighted. A new seabird has been discovered by an international expedition headed by one of the world's top seabird-experts, Peter Harrison, after he received photos from vacationing birders of an unusual looking storm petrel off the coast of Chile.
Conservationists oppose snow leopard hunt for 'science'
(03/23/2011) Conservationists have come out in opposition against a plan by the Mongolian government to issue four permits to kill snow leopards (Panthera uncia ) for 'scientific research'. The permits were awarded to foreign nationals last month. Snow leopards are listed as Endangered by the IUCN Red List with their population declining. "If the planned hunting of snow leopards is allowed to go forward, Mongolia's creditability as a leader in conservation of [snow leopards] and other rare species will be severely tarnished," reads a letter from Tom McCarthy, Executive Director of Panthera's Snow Leopard Program and George Schaller, Vice President of Panthera, to Mongolia's Minister of Nature, Environment, and Tourism.
Photos: penguins devastated by oil spill
(03/22/2011) Disturbing photos show northern rockhopper penguins (Eudyptes moseleyi) hit hard by an oil spill from a wrecked cargo ship on Nightingale Island in the Southern Atlantic. Already listed as Endangered by the IUCN Red List, the oil spill threatens nearly half of the northern rockhopper population according to BirdLife International. Already conservation workers say 'hundreds' of penguins have been oiled. Located the remote Southern Atlantic, Nightingale Island is a part of the UK's Tristan da Cunha archipelago. The island's are home to a variety of birdlife, including species that survive no-where else but on the archipelago.
Hundreds of endangered penguins covered in oil after remote spill
(03/21/2011) Conservation workers have found hundreds of oiled northern rockhopper penguins (Eudyptes moseleyi) after a cargo vessel wrecked on Nightingale Island, apart of the UK's Tristan da Cunha archipelago. Northern rockhopper penguins are listed as Endangered by the IUCN Red List. According to a press release by BirdLife International, the spill threatens nearly half of the world's northern rockhopper population.
Expedition granted?: Indonesia's 'paper parks' targeted in National Geographic contest
(03/21/2011) Twenty-five year old Trevor Frost wants to save parks in Indonesia under attack by illegal logging, mining, and poaching. A lack of infrastructure, support, and funds has left many protected areas around the world to be dubbed 'paper parks', protected on paper, but not in reality. Frost, who is currently running in National Geographic's contest Expedition Granted, hopes to study the problem in Sumatra—among the world's most imperiled forests and wildlife—and show the world what we are losing even in National Parks.
Pet trade, palm oil, and poaching: the challenges of saving the 'forgotten bear'
(03/20/2011) Siew Te Wong is one of the few scientists who study sun bears (Ursus malayanus). He spoke with Laurel Neme on her "The WildLife" radio show and podcast about the interesting biological characteristics of this rare Southeast Asian bear, threats to the species and what is being done to help them. Sun bears are the smallest of the eight bear species. They’re about half the size of a North American black bear and typically sport a tan crescent on their chests. Similar to the "moon bear," or Asian black bear, the sun bear’s name comes from this marking, which looks like a rising or setting sun.
Oil exploration on hold in Virunga National Park—for now
(03/17/2011) The Democratic Republic of Congo (DRC) has suspended oil exploration in Africa's oldest national park, Virunga, until a Strategic Environmental Assessment (SEA) is conducted. The move ends oil companies, Soco and Dominion's plans to explore for oil in blocs within the park that were awarded to the companies last year.
Goodbye national parks: when 'eternal' protected areas come under attack
(03/17/2011) One of the major tenets behind the creation of a national park, or other protected area, is that it will not fade, but remain in essence beyond the pressures of human society, enjoyed by current generations while being preserved for future ones. The protected area is a gift, in a way, handed from one wise generation to the next. However, in the real world, dominated by short-term thinking, government protected areas are not 'inalienable', as Abraham Lincoln dubbed one of the first; but face being shrunk, losing legal protection, or in some cases abolished altogether. A first of its kind study, published in Conservation Letters, recorded 89 instances in 27 countries of protected areas being downsized (shrunk), downgraded (decrease in legal protections), and degazetted (abolished) since 1900. Referred to by the authors as PADDD (protected areas downgraded, downsized, or degazetted), the trend has been little studied despite its large impact on conservation efforts.
Serengeti road project opposed by 'powerful' tour company lobby
(03/16/2011) Government plans to build a road through Serengeti National Park came up against more opposition this week as the Tanzanian Association of Tour Operators (Tato) came out against the project, reports The Citizen. Tato, described as powerful local lobby group by the Tanzanian media, stated that the road would hurt tourism and urged the government to select a proposed alternative route that would by-pass the park. Tato's opposition may signal a shift to more local criticism of the road as opposition against the project has come mostly from international environmentalists, scientists, and governments.
New road project to run through Laos' last tiger habitat
(03/15/2011) A new road project in Laos will run through the nation's only protected area inhabited by breeding tigers, Nam Et Phou Louey National Park, reports the Vientiane Times. With only about two dozen tigers (Panthera tigris) left in the nation, conservationists fear that the road will harm the fragile population, which is known to be breeding. However, local officials say the road is necessary to improve access to remote villages and alleviate poverty in the region, which is among the worst in the province.
15 conservation issues to watch
(03/14/2011) Deforestation, oil spills, coral acidification: these are just a few examples of ongoing, and well-researched, environmental changes that are imperiling the world's biodiversity. But what issues are on the horizon? At the end of 2010, experts outlined in Trends in Ecology & Evolution 15 issues that may impact conservation efforts this year and beyond, but are not yet widely known. These are issues you may never hear about it again or could dominate tomorrow's environmental headlines. "Our aim was to identify technological advances, environmental changes, novel ecological interactions and changes in society that could have substantial impacts on the conservation of biological diversity […] whether beneficial or detrimental," the authors write in the paper. Experts originally came up with 71 possible issues and then whittled it down to the 15 most important—and least known.
CEO sentenced for smuggling elephant ivory into US
(03/14/2011) A judge sentenced Pascal Vieillard, CEO of A-440 Pianos Inc., to 3 years probation for illegally smuggling elephant ivory into the US, while the Georgia-based company has been fined $17,500. Vieillard had earlier pleaded guilty to importing pianos with ivory parts.
Fearful Symmetry—Man Made, an interview with John Vaillant, author of The Tiger
(03/14/2011) In The Tiger, John Vailliant weaves a haunting and compelling true narrative of men who live—or die—with tigers. No doubt the story itself is on-the-edge of your seat reading. As well, the book provides factual information on the 400 or so Amur Tigers remaining, and the raw milieu that is Primorye, Far East Russia—a wilderness and people unto their own. What is special, transcendent even in this story, however, murmurs uncomfortably in the background. Questions emerge from deep taiga snow, not unlike the unseen Panchelaza Tiger. What exactly is our relationship with apex predators? How do people live with them? How would you live with them in your backyard? What if your pet dog disappeared? As we ourselves are apex predators, are we wise enough, tolerant enough, compassionate enough to share this planet with them? Evidence today points to the contrary, but this can change.
'Cute' umbrella video of slow loris threatens primate
(03/13/2011) A new video of a slow loris holding an umbrella in a pet store has been viewed nearly a million and a half times, yet such viral videos may imperil these 'cute' and endangered primates by encouraging an illegal and often cruel pet trade. "Most people who see them in this setting want one, too!" says Angelina Navarro-Montes, a graduate student at Oxford Brookes University who has conducted studies of the slow-loris Internet trade, told mongabay.com in 2009. "There is also a big misconception on [YouTube] and a lot of viewers think it’s perfectly legal to have them as pets."
Into Colombia's Sierra Nevada
(03/11/2011) The highest coastal mountain on the planet rises 18,942 feet (5,775-meters) above the Caribbean Sea; it’s snow-capped peaks piercing through the clouds some 24 miles from an idyllic tropical beach. But to the casual visitor, the Sierra Nevada of Santa Marta in Colombia does not seem so grandiose. It slopes up and down until it disappears into the clouds, jealously concealing its tropical glacier. Somewhere up there, shrouded in mystery, like an ancient treasure, hides the most impressive summit in the Caribbean. People living along this part of the coastline say the snows of the Sierra are visible from some beaches, but to me they remain elusive even after many trips to the region. To catch a glimpse of the snows from the Caribbean would be a welcoming gift, but I have really come here to experience the Sierra, whatever it would reveal.
Cambodians prevented from protesting destruction of their forest
(03/10/2011) Cambodian villagers fighting to save their forest from rubber companies have been rebuked by the local government. Two days in a row local authorities prevented some 400 Cambodian villagers from protesting at the offices of the Vietnam-based CRCK Company, which the villagers contend are destroying their livelihoods by bulldozing large swaths of primary forests. Authorities said they feared the villagers would have grown violent while protesting.
Critically endangered capuchins make tools to gather termites
(03/10/2011) Less than 200 blond capuchins (Cebus falvius) survive in the highly-fragmented habitat of Brazil's Atlantic Forest. But this tiny group of monkeys, only rediscovered in 2006, is surprising scientists with its adept tool-using abilities. Displaying similar behavior to that which made the chimpanzees of Gombe famous worldwide, the blond capuchins modify sticks to gather termites from trees; however, according to the study published in Biology Letters the blond capuchins use two techniques never witnessed before: twisting the stick when inside the termite nest and tapping the nest before inserting the stick.
Mitsubishi and Walmart agree to clean up fish sourcing practices
(03/09/2011) Two big players in seafood today announced that they are changing the way their fish are caught. Mitsubishi, which owns the UK's most popular brand for tuna in a tin, Princes, and Walmart, which owns Asda, have agreed to stop buying from fishermen who use purse seines fishing in conjunction with fish aggregating devices (FADs) by 2014. These methods have been blamed in part for the vast overfishing of the world's tuna and helping to decimate other species, such as sharks and rays, as bycatch.
Photos: two new freshwater stingrays discovered in the Amazon
(03/09/2011) Few people probably realize that in the rivers and lakes of the Amazon rainforest large stingrays glide, searching for crustaceans and small fish. Equipped with a powerful barbed tail they are often feared by locals. However, even as big as these fish are, new species continue to be described. Recently, scientists have identified two new species of Amazonian freshwater stingray near Iquitos, Peru. The new stingrays are unique enough to be placed in a new genus (the taxonomic level above species) called Heliotrygon, the first new Amazonian stingray genus to be described in nearly 25 years.
Birds experience 'empathy' for their hatchlings
(03/09/2011) A new study has uncovered what many chicken owners would say is evident: a mother hen experiences empathy for her hatchlings. Published in the Proceedings of the Royal Society B, the study found that mother hens show both physiological responses and changes in behaviors when their chicks are even mildly distressed.
India plans to aid dwindling Ganges River dolphin
(03/08/2011) The Indian government has announced that it plans to develop a program to raise the population of its native Ganges river dolphin (Platanista gangetica gagnetica), a subspecies of the South Asian river dolphin. During a question and answer session Jairam Ramesh, India's Environment and Forests Minister, said that the dolphin's current population was estimated at 2,000 to 3,000 individuals in the Ganges. However, other estimates have placed it lower.
Elephants cooperate as well as chimps
(03/07/2011) A new study proves that elephants understand how sometimes two is better than one. Working with Asian elephants (Elephas maximus) at the Thai Elephant Conservation Center, researchers reconstructed a classic cooperation test that was originally developed for chimpanzees. Subjects must pull on a rope to receive a reward, such as food, however—and here's the crux—the treat is only released if two subjects cooperate by pulling on two different ropes simultaneously. The paper published in Proceedings of the National Academy of Sciences found that elephants were as capable of cooperation as chimpanzees.
