In tungara frogs, female choice for complex calls led to evolution of unusual male vocal cord
(5/3/2006) Male tropical tungara frogs have evolved masses on their vocal cords that help them woo females with complex calls, show scientists working at the Smithsonian Tropical Research Institute (STRI) in Panama.


16,119 species at risk of extinction
(5/2/2006) The number of known threatened species reaches 16,119. The ranks of those facing extinction are joined by familiar species like the polar bear, hippopotamus and desert gazelles; together with ocean sharks, freshwater fish and Mediterranean flowers. Positive action has helped the white-tailed eagle and offers a glimmer of hope to Indian vultures. The total number of species declared officially Extinct is 784 and a further 65 are only found in captivity or cultivation. Of the 40,177 species assessed using the IUCN Red List criteria, 16,119 are now listed as threatened with extinction. This includes one in three amphibians and a quarter of the world's coniferous trees, on top of the one in eight birds and one in four mammals known to be in jeopardy


Pacaya Samiria National Reserve: Macaws, monkeys, and...illegal loggers?
(5/2/2006) Yesterday started out like a normal day. We swatted bugs, and slowly baked in the hot, equatorial sun. However, as the day progressed, large, dark clouds appeared on the horizon, and the trees top began to sway violently back and forth. Within seconds the sky let loose. It began raining so hard that it was difficult to tell where the river stopped and the air began.


Evolution is twice as fast in the tropics
(5/1/2006) Tropical species evolve twice as fast as temperate species according to research published in Tuesday's Proceedings of the National Academy of Sciences (PNAS). The study. which compared the genetics of 45 common tropical plants with similar species from cooler geographical areas, suggests that evolution takes place at a faster rate in warmer climates due to higher rates of metabolism, which leads to more genetic mutation, and shorter generations, so genetic changes are rapidly passed on to offspring. The researchers found that tropical plant species -- including species from Borneo, New Guinea, northeast Australia and South America -- had more than twice the rate of molecular evolution as closely related species in temperate parts of North America, southern Australia, Eurasia and New Zealand.


Forest restoration important in Guyana
(5/1/2006) Located on the northern edge of South America, bordered by Suriname, Brazil, Venezuela, and the Atlantic Ocean, lays a small but vibrant country with a wealth of culture, biodiversity and opportunity. During the week of 13-17 March 2006, representatives from Guyanese government departments, civil society and indigenous peoples' organizations met in the capital city, Georgetown, with the World conservation Union (IUCN) and the International Tropical Timber Organization at a national workshop on Forest Landscape Restoration (FLR). The workshop introduced the concept of FLR with the intention of better understanding how it may be applied in the Guyana context.


Corals may survive global warming by gorging themselves
(4/26/2006) A new study published in Nature says some coral are able to survive bleaching events by gorging themselves. An experiment with Hawaiian corals showed that when bleached, one species sharply increased its intake of food, increasing the likelihood that it would survive elevated water temperatures.


6 species of frogs discovered in Laos
(4/20/2006) Six new species of frogs have been discovered in the Southeast Asia nation of Lao PDR, according to the Bronx Zoo-based Wildlife conservation Society (WCS). Three newly discovered frog species are described in the recent issue of Copeia, the journal of the American Society of Herpetologists and Ichthyologists. WCS says that little is known about the new frogs, other than the location they were found and how the compare morphologically to similar species.


Lizard gives clues on evolution of eye
(4/14/2006) Lizards have given Johns Hopkins researchers a tantalizing clue to the evolutionary origins of light-sensing cells in people and other species. The lizard study describes how the lizard's so-called third, or parietal, eye, distinguishes two different colors, blue and green, possibly to tell the time of day. Specialized nerve cells in that eye, which looks more like a spot on the lizard's forehead, use two types of molecular signals to sense light: those found only in simpler animals, like scallops, and those found only in more complex animals like humans. Although the blue-green color comparison method used by the parietal eye is not one shared by humans, it does reveal one potential step in the evolution of color vision, the Hopkins researchers say. The proponents of intelligent design assert that the combination of nerves, muscles, sensory cells, and lens tissue in the eye could only have been 'designed' from scratch but this new research gives new insight into the evolutionary development of light-sensing cells, key to the eventual development of eye-like structures and color vision.


Global warming could doom the walrus finds new study
(4/14/2006) Add the walrus to the list of species threatened by climate change. A new study finds unprecedented pup abandonment in the Arctic due to disappearing sea ice. A new study warns that walrus calves are being stranded by melting sea ice in the Arctic Ocean. Researchers aboard the U.S. Coast Guard icebreaker Healy during a cruise in the Canada Basin in the summer of 2004 found lone walrus calves swimming far from shore--something never before documented. The sightings suggest that increased polar warming may be forcing mothers to abandon their pups as they follow the rapidly retreating ice northwards. If these observations portray a larger trend, a warming Arctic ice may lead to decreases in the walrus population say the scientists whose research was published in the April issue of Aquatic Mammals.


Forest protection best way to control rats finds study
(4/13/2006) The most cost-effective way to stop non-native rats and mongoose from decimating highly endangered species on larger tropical islands is not by intensive trapping, but instead by preserving the forest blocks where wildlife live, according to a study by the Bronx Zoo-based Wildlife conservation Society (WCS) and other groups.


Rainforest education site goes online; resources for students, teachers, and journalists
(4/12/2006) Mongabay.com, a leading environmental-science web site, announced today a revised version of a rainforest site, that has been a major resource on such forests for teachers, children, and researchers. "Mongabay.com is dedicated to providing necessary communication to those interested in the fate of our rainforests," Ira Rubinoff, director of the Smithsonian Tropical Research Institute (STRI), said. "It has a scientific base that should provide reliable information to all who share an interest in the future quality of life on this planet." The revised site includes environmental profiles and deforestation statistics for more than 60 countries, and features thousands of rainforest wildlife photos from around the world. Additionally, the site includes a section geared towards children, with learning activities and educational resources for teachers.


Climate change is serious threat to biodiversity
(4/11/2006) The Earth could see massive waves of species extinctions around the world if global warming continues unabated, according to a new study published in the scientific journal conservation Biology.


Nitrogen emissions could sink plant species in biodiversity hotspots
(4/11/2006) Rising nitrogen emissions from human activities -- such as fossil fuel burning and livestock farming -- may soon threaten plant species in some of the world's most biodiverse places according to researchers at the Universities of Sheffield and York.


Tropical deforestation rates to slow in future - new study
(4/6/2006) As human population growth rates diminish in coming years deforestation rates are expected to slow according to research published in Biotropica online. The report offers hope that reduced rates of forest conversion can stave off a future extinction crisis in the tropics, where most of the world's biodiversity is found. Scientists estimate that as much as 50 percent of the planet's terrestrial biodiversity is found in tropical rainforests distributed around the world but the United Nations recently warned that the current rate of extinction is running 100 to 1,000 times the normal background rate.


Recent Coral Bleaching at Great Barrier Reef
(4/5/2006) An international team of scientists are working at a rapid pace to study environmental conditions behind the fast-acting and widespread coral bleaching currently plaguing Australia's Great Barrier Reef. NASA's satellite data supply scientists with near-real-time sea surface temperature and ocean color data to give them faster than ever insight into the impact coral bleaching can have on global ecology. Australia's Great Barrier Reef is a massive marine habitat system made up of 2,900 reefs spanning over 600 continental islands. Though coral reefs exist around the globe, researchers actually consider this network of reefs to be the center of the world's marine biodiversity, playing a critical role in human welfare, climate, and economics. Coral reefs are a multi-million dollar recreational destinations, and the Great Barrier Reef is an important part of Australia's economy.


Newly discovered rodent not so new or rare after all
(4/5/2006) The newly discovered species of rodent found in a marketplace in Central Laos turns out to not be so new or so rare after all. The Laotian rock rat (Laonastes aenigmamus), as the long-whiskered and stubby-legged rodent is now known, is a species believed to have been extinct for 11 million years. It is a member of a family that, until now, was only known from the fossil record. The species was first described by Wildlife conservation Society (WCS) researcher Dr. Robert Timmins after it was found on a table at a hunter's market in central Laos. In a return trip to the market, WCS conservationist Peter Clyne found the rats to be quite common, photographing several specimens. According to Clyne, the rat is commonly brought in by hunters and eaten by local people.


Insects worth $57 billion to US economy
(4/1/2006) A new study says insects are worth at least $57 billion to the American economy. In the April 2006 issue of BioScience, John E. Losey of Cornell University and Mace Vaughan of the Xerces Society for Invertebrate conservation estimate the value of ecological services provided by insects. Looking at just four services--dung burial, control of crop pests, pollination, and wildlife nutrition--Losey and Vaughan calculate that the annual value of insects in these roles is at least $57 billion in the United States.


Does tropical biodiversity increase during global warming?
(3/30/2006) Forest fragmentation may cause biodiversity loss lasting millions of years according to a new study published in the March 31, 2006 issue of the journal Science. Using cores drilled through 5 kilometers of rock in eastern Colombia and western Venezuela, Carlos Jaramillo of the Smithsonian Tropical Research Institute (STRI) in Panama and a team of researchers derived a fossil pollen record for a 72 million-year period with samples ranging from 10 to 82 million years ago.


Shahtoosh becomes illegal as Tibetan antelope is protected
(3/30/2006) The Bronx Zoo-based Wildlife conservation Society today applauded a decision by the U.S. Fish and Wildlife Service to list the Tibetan antelope, also known as chiru, as an endangered species. Through a series of expeditions to China's windswept Chang Tang Reserve over the past two decades, WCS had played a key role in sounding the alarm about the dramatic decline of this elegant animal due to poaching.


Avian Flu Threat to Biological Diversity
(3/23/2006) A far wider range of species including rare and endangered ones may be affected by highly virulent avian flu than has previously been supposed. Experts attending the Convention on Biological Diversity (CBD) conference say there is growing evidence that the H5N1 virus can infect and harm big cats like leopards and tigers, small cats such as civets and other mammals like martens, weasels, badgers and otters.


Red Tide Causes Sea Turtle Die-Off in El Salvador
(3/23/2006) A Red Tide event that occurred off the coast of El Salvador late last year directly caused the deaths of some 200 sea turtles, according to test results released today by the Wildlife conservation Society (WCS) and other organizations.


Jungle trekking in Malaysia's Taman Negara
(3/21/2006) Taman Negara is Malaysia's largest and best-known national park. Spanning 4343 square kilometers, the protected forest area is home to some of southeast Asia'apos;apos;s rarest creatures including tigers, the Malaysian tapir, forest elephants, and the Sumatran rhino. Scientists believe that these rainforests may be the oldest on Earth. Untouched by glaciers during recent ice ages, Taman Negara'apos;apos;s forests have remained largely the same for some 130 million years. This stability produces some of the highest levels of biodiversity on Earth: more than 350 species of birds, 14000 species of plants, and 210 species of mammals can be found in Taman Negara.


Global biological diversity in decline
(3/20/2006) Global biological diversity is increasingly threatened according to a report released by at the outset of the largest biodiversity conference in more than a decade.

Predator control fails to help sheep industry
(3/15/2006) Decades of U.S. government-subsidized predator control has failed to prevent a long-term decline in the sheep industry, according to a study by the Wildlife conservation Society, which says that market forces are responsible for the drop-off in sheep numbers.


Harmless frogs gain protection by mimicking toxic species
(3/13/2006) When predators learn to avoid a highly toxic frog, they generalize, and this allows a harmless frog to mimic and be more abundant than a frog whose poison packs less punch, biologists at The University of Texas at Austin studying poison dart frogs in the Amazon have discovered.


Crazy jungle rodent is 11 million years old
(3/9/2006) The newly discovered species of rodent found in a marketplace in Central Laos turns out to not be so new after all.

African carnivores under threat -- top 20 at risk listed
(2/1/2006) It may still be king of the beasts, but the African lion's kingdom is dwindling, according to a new report released by the New York-based Wildlife conservation Society (WCS) that says these emblematic big cats have disappeared from 82 percent of their historic distribution over the past several decades. The 200-page report looked at the conservation status of the 20 largest species of African carnivores and examined priorities to help ensure that they persist on the continent.


World's smallest fish title in dispute
(1/30/2006) Researchers dispute last week's claim of world's smallest fish in Sumatra. Evidence of an even smaller fish--a species of marine anglerfish 20 percent smaller than the carp found in southeast Asia--is presented by a University of Washington professor of aquatic and fisheries sciences. In a release from the University of Washington, professor Pietsch describes the tiny anglerfish, Photocorynus spiniceps, found in the Philippines.
