(05/01/2011) As the honorary speaker at an event celebrating fifty years of the conservation organization World Wide Fund for Nature (WWF), Archbishop Desmond Tutu stated that overconsumption and obsession with economic growth were imperiling the global environment and leaving the poor behind.
New eco-tour to help save bizarre antelope in 'forgotten' region
(05/01/2011) Imagine visiting a region that is largely void of tourists, yet has world-class bird watching, a unique Buddhist population, and one of the world's most bizarre-looking and imperilled mammals: the saiga. A new tour to Southern Russia hopes to aid a Critically Endangered species while giving tourists an inside look at a region "largely forgotten by the rest of the world," says Anthony Dancer. Few species have fallen so far and so fast in the past 15 years as Central Asia's antelope, the saiga. Its precipitous decline is reminiscent of the bison or the passenger pigeon in 19th Century America, but conservationists hopes it avoids the fate of the latter.
With 24 eyes, box jellyfish are constantly looking up
(04/28/2011) Lacking brains does not mean box jellyfish are incapable of complex visual behavior, according to a new study in Current Biology. Researchers have known for over a century that box jellyfish support an astounding two-dozen eyes. Now, they are beginning to find out how these eyes are used: four of a box jellyfish's 24 eyes are always peering up out of the water finds the new study. These four eyes, no matter how the body is oriented, allow the jellyfish to navigate their shallow, obstacle-filled habitats, such as mangroves—and keep them from straying too far from home.
Are US floods, fires linked to climate change?
(04/28/2011) The short answer to the question of whether or not on-going floods in the US Midwest and fires in Texas are linked to a warming Earth is: maybe. The long answer, however, is that while it is difficult—some argue impossible—for scientists to link a single extreme weather event to climate change, climate models have long shown that extreme weather events will both intensify and become more frequent as the world continues to heat up. In other words, the probability of such extreme events increases along with global average temperature.
With pressure to drill, what should be saved in the Arctic?
(04/27/2011) Two major threats face the Arctic: the first is global climate change, which is warming the Arctic twice as fast the global average; the second is industrial expansion into untouched areas. The oil industry is exploring new areas in the Arctic, which they could not have reached before without anthropogenic climate change melting the region’s summer ice; but, of course, the Arctic wouldn't be warming without a hundred years of massive emissions from this very same industry, thus creating a positive feedback loop that is likely to wholly transform the Arctic.
Rising food prices threaten to push over 60 million Asians back into poverty
(04/27/2011) The Asian Development Bank has warned that high food prices on the continent could push 64 million people in developing countries into extreme poverty, reports the AFP.
In spite of poaching, Nepal's rhino population on the rise
(04/27/2011) Good news for rhinos is rare recently, but a new census shows that Nepal's one-horned rhino (Rhinoceros unicornis) population has increased by 23% since 2008 even in the face of poaching. In total 534 rhinos survive in Nepal, a rise of 99 individuals from 3 years ago.
Rise in wildlife tourism in India comes with challenges
(04/27/2011) A line of tourist jeeps clogs the road in a dry forest, as all eyes—and cameras—are on a big cat ambling along the road ahead; when the striped predator turns for a moment to face the tourists, voices hush and cameras flash: this is a scene that over the past decade has becoming increasingly common in India. A new study in Conservation Letters surveyed ten national parks in India and found that attendance had increased on average 14.9% from 2002-2006, but while rising nature tourism in India comes with education and awareness opportunities, it also brings problems.
Save the Frogs Day focuses on banning Atrazine in US
(04/26/2011) This year's Save the Frogs Day (Friday, April 29th) is focusing on a campaign to ban the herbicide Atrazine in the US with a rally at the steps of the Environmental Protection Agency (EPA). Kerry Kriger, executive director of frog-focused NGO Save the Frogs! and creator of Save the Frogs Day, says that Atrazine is an important target in the attempt to save amphibians worldwide, which are currently facing extinction rates that are estimated at 200 times the average. "Atrazine weakens amphibians' immune systems, and can cause hermaphroditism and complete sex reversal in male frogs at concentrations as low as 2.5 parts per billion," Kriger told mongabay.com.
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.
Mexican environmental activist shot dead
(04/25/2011) Javier Torres Cruz, 30, who fought illegal deforestation by drug traffickers in the Mexican state of Guerroro, was murdered a week ago. A member of the local NGO, Environmental Organization of the Coyuca and Petatlán Mountains, Torres Cruz was known as an outspoken activist against illegal logging in the mountainous dry forest region. Logging in the region is primarily linked to fields of poppies for the illegal drug trade.
Obama focuses on climate change in Earth Day proclamation
(04/22/2011) After a long absence of speaking directly to the issue of climate change—he did not mention it once in his State of the Union speech in January—US President Barack Obama used his Earth Day proclamation to focus on it.
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.
Forest carbon map released for the US
(04/20/2011) The Woods Hole Research Center (WHRC) has released the first hectare-scale map displaying aboveground woody biomass and forest carbon in US forests. The map, which also shows canopy heights, is known as the National Biomass and Carbon Dataset (NBCD).
Demand for gold pushing deforestation in Peruvian Amazon
(04/19/2011) Deforestation is on the rise in Peru's Madre de Dios region from illegal, small-scale, and dangerous gold mining. In some areas forest loss has increased up to six times. But the loss of forest is only the beginning; the unregulated mining is likely leaching mercury into the air, soil, and water, contaminating the region and imperiling its people. Using satellite imagery from NASA, researchers were able to follow rising deforestation due to artisanal gold mining in Peru. According the study, published in PLoS ONE, Two large mining sites saw the loss of 7,000 hectares of forest (15,200 acres)—an area larger than Bermuda—between 2003 and 2009.
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.
NASA image reveals extent of 2010 Amazon drought
(04/17/2011) NASA has revealed a satellite image of the crippling effect of last year's record-breaking drought on the Amazon ecosystem. For those of you counting, that's two record droughts in the Amazon Basin in 5 years.
Indonesia and the EU reach agreement on illegal wood trade
(04/17/2011) A new agreement will work to keep illegal wood from Indonesia out of European Union markets. The Voluntary Partnership Agreement (VPA) will force Indonesia to only ship wood to the EU that has been approved as legal by a national authority, while EU customs workers are set to send any unapproved wood back to Indonesia. The VPA is a step forward in tackling the illegal timber market in Indonesia that is estimated to be worth $1 billion and has been responsible, in part, for leveling rainforests across the Indonesia islands.
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.
Gas from 'fracking' not climate friendly
(04/13/2011) It appears every time a fossil fuels industry claims its energy is 'green' or 'climate-friendly', scientists discover this just isn't so. The most recent culprit is natural gas produced by an already controversial method known as hydraulic fracturing, or fracing, which extracts the gas from shale basins. A new study in Climatic Change has found that the process of fracing is worse than coal over a 20-year period and about equal over 100-years. Coal had long been considered the worst climate offender of all energy options.
Satellite evidence of deforestation in uncontacted tribe's territory sparks legal action
(04/12/2011) The destruction of 3,600 hectares (8,900 acres) of the Gran Chaco forest in Paraguay by large Brazilian cattle ranching companies has led to a legal complaint filed by a local indigenous-rights organization, since the land in question was one of the last refuges of a group of uncontacted indigenous people in the Ayoreo-Totobiegosode tribe. The loss of the forest was revealed in part by satellite images of the remote area.
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.
More biodiversity equals cleaner water, but why?
(04/07/2011) A new landmark study not only proves that adding more species to a freshwater stream linearly increases the ecosystem's ability to clean pollutants, but also shows why. The study, published in Nature found that by increasing the biodiversity of a lab controlled mini-stream from one algae species to eight caused the ecosystem to soak up nitrate pollution 4.5 times faster on average. To conduct the experiment, researchers used plastic to create 150 mini model streams. Molding the plastic, they recreated real stream-like habitats such as pools, runs, and eddies. Different species of algae gravitated toward particular mini-habitats, creating special ecological niches and allowing more of the stream to be utilized by the algae for soaking up the nitrate pollution. Less utilization of the available habitats resulted in a dirtier river and vice-versa.
Indigenous group claims Ecuadorian government complicit in 'genocide'
(04/06/2011) Ecuador's paramount indigenous organization has filed a legal complaint against the government, including President Rafael Correa, for allegedly participating in 'genocide' against indigenous people in the Amazon. The Confederation of Indigenous Nationalities of Ecuador (CONAIE) is arguing that expanding oil exploration and mining is imperiling the lives of uncontacted tribes that have chosen voluntary isolation known as the Tagaeri and the Tarmenane, reports the AFP.
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."
Japan disaster to put logging pressure on rainforests in Indonesia, Malaysia
(04/05/2011) The tragic earthquake and tsunami that hit Japan last month is likely to boost wood imports into the recovering nation, adding increased pressure on the already imperiled rainforests of Southeast Asia. Even before the disaster, Japan was the world's number one importer of wood chips and plywood and the second largest importer of logs. Japan usually imports plywood from China, Malaysia, and Indonesia, however the forests of Southeast Asia are facing tremendous loss due to logging and clearing for industrial-scale agriculture, such as palm oil.
Vanishing mangroves are carbon sequestration powerhouses
(04/05/2011) Mangroves may be the world's most carbon rich forests, according to a new study in Nature Geoscience. Measuring the carbon stored in 25 mangrove forests in the Indo-Pacific region, researchers found that mangroves forests stored up to four times as much carbon as other tropical forests, including rainforests. "Mangroves have long been known as extremely productive ecosystems that cycle carbon quickly, but until now there had been no estimate of how much carbon resides in these systems. That's essential information because when land-use change occurs, much of that standing carbon stock can be released to the atmosphere," explains co-author Daniel Donato, a postdoctoral research ecologist at the Pacific Southwest Research Station in Hilo, Hawaii.
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.
World Bank proposes to limit funding to coal plants
(04/05/2011) Following years of criticism from environmentalists and some governments the World Bank has proposed new rules regarding carbon-intensive coal plants, reports the Guardian. The new rules would allow lending for coal-fired plants only to the world's poorest nations and would only lend after other alternatives, such as renewable energy, had been ruled out.
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.
'Luck and perseverance': new plant genus discovered in Amazon
(03/31/2011) The discovery of a new plant species is not uncommon, especially in places of remarkable biodiversity such as the Amazon rainforest. However, discovering a new plant genus, a taxonomic rank above species, is, according to Henk van der Werff fromt the Missouri Botanical Garden (MBG), "a matter of luck and perseverance". Researchers with the Missouri Botanical Garden have been blessed with both as they have announced two new species of Amazonian plants, one from Ecuador and one from Peru, that comprise a completely new genus: named, Yasunia, since the plant was originally discovered in Ecuador's vast Yasuni National Park.
Carbon labeling good for consumers and business
(03/31/2011) Want to know how many calories are in a serving from that box of cereal? Simply turn it over and you can read a wealth of information: calories, fat, fiber, nutrients. But what if you’d like to know how much carbon was emitted to produce your breakfast? Currently, you're out of luck. But an article in Nature Climate Change argues that labeling products—from food to household products—with their carbon footprint could reduce emissions over time as consumers and companies react to better environmental transparency. A 'carbon footprint' measures the total amount of greenhouse gases emitted to produce a product or service.
'Huge reduction' of water from plants due to higher carbon levels
(03/30/2011) As if ocean acidification and a warming world weren't enough, researchers have outlined another way in which carbon emissions are impacting the planet. A new study shows that higher carbon dioxide levels in the atmosphere have taken a toll on how much water vapor plants release, potentially impacting the rainfall and groundwater sources. A study in the Proceedings of the National Academy of Sciences (PNAS) has found that carbon dioxide levels over the past 150 years has reduced plants' spores, called stomata, by over one third (34%). This is important because stomata take in oxygen and carbon dioxide and release water vapor in a process dubbed 'transpiration'. Less stomata means less water driven into the atmosphere.
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.
Last year's drought hit Amazon hard: nearly a million square miles impacted
(03/29/2011) A new study on its way to being published shows that the Amazon rainforest suffered greatly from last year's drought. Employing satellite data and supercomputing technology, researchers have found that the Amazon was likely hit harder by last year's drought than a recent severe drought from 2005. The droughts have supported predictions by the Intergovernmental Panel on Climate Change's (IPCC) that climate change, among other impacts, could push portions of the Amazon to grasslands, devastating the world's greatest rainforest. "The greenness levels of Amazonian vegetation—a measure of its health—decreased dramatically over an area more than three and one-half times the size of Texas and did not recover to normal levels, even after the drought ended in late October 2010," explains the study's lead author Liang Xu of Boston University.
Amazon still neglected by researchers
(03/28/2011) Although the Amazon is the world's largest tropical forest, it is not the most well known. Given the difficulty of access along with the fear of disease, dangerous species, indigenous groups, among other perceived perils, this great treasure chest of biology and ecology was practically ignored by scientists for centuries. Over the past few decades that trend has changed, however even today the Amazon remains lesser known than the much smaller, and more secure, tropical forests of Central America. A new study in mongabay.com's open access journal Tropical Conservation Science, which surveyed two prominent international tropical ecology journals (Biotropica and Journal of Tropical Ecology) between 1995 and 2008, finds that Central America was the subject of twice as many studies as the Amazon. In fact, according to the authors, much of the Amazon remains terra incognito to researchers, even as every year more of the rainforest is lost to human impacts.
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.
