Museum specimens aid conservation effort in Madagascar
There is a new tool for those developing conservation strategies for threatened species and landscapes: museum specimens. Richard Pearson and Christopher Raxworthy of the American Museum of Natural History dusted off a number of collections from Madagascar and used the location information associated with each species to test different ideas... view more...

A global model for the origin of species independent of geographical isolation
The tremendous diversity of life continues to puzzle scientists, long after the 200 years since Charles Darwin's birth. view more (2009-07-20)
Hundreds of New Species Discovered in Fragile Eastern Himalayas
Over 350 new species including the world's smallest deer, a "flying frog" and a 100 million-year old gecko have been discovered in the Eastern Himalayas, a biological treasure trove now threatened by climate change. view more (2009-08-11)
Rare Tibetan antelope listed as endangered
The Bronx Zoo-based Wildlife Conservation Society (WCS) today applauded a decision today by the U.S. Fish and Wildlife Service to list the Tibetan antelope, also known as "chiru," as an endangered species. view more (2006-03-31)
DNA 'barcode' identified for plants
A 'barcode' gene that can be used to distinguish between the majority of plant species on Earth has been identified by scientists who publish their findings in the Proceedings of the National Academy of Sciences journal. view more (2008-02-06)
Ant has given up sex completely, report Texas researchers
The complete asexuality of a widespread fungus-gardening ant, the only ant species in the world known to have dispensed with males entirely, has been confirmed by a team of Texas and Brazilian researchers. view more (2009-08-26)
American carnivores evolved to avoid each other, new study suggests
How do the many carnivorous animals of the Americas avoid competing for the same lunch, or becoming each other's meal? view more (2009-03-10)
Young children think gender-related behavior is inborn
Young children think about gender in the same way they think about species of animals. They believe, for example, that a boy's preference for football is innate, as is a girl's preference for dolls, just as cats' behavior is innately different from dogs'. view more (2009-04-29)
UT researcher sheds new light on hybrid animals
What began more than 50 years ago as a way to improve fishing bait in California has led a University of Tennessee researcher to a significant finding about how animal species interact and that raises important questions about conservation. view more (2007-09-18)
New golden frog discovered in remote region of Colombia
A new poisonous frog was recently discovered in a remote mountainous region in Colombia by a team of young scientists supported by the Conservation Leadership Programme (CLP). view more (2007-08-29)
Improved estimates of population extinction risk (Harding and McNamara)
An important application of theoretical ecology is in estimation of species extinction risk. Extinction models guide the selection of management regimes for endangered species. Two vital parameters in these models are the mean population growth rate and its variance. However, empirical data on population growth are rarely perfect, but are... view more... (2003-12-10)
Thriving Hybrid Salamanders Contradict Common Wisdom
A new UC Davis study not only has important findings for the future of California tiger salamanders, but also contradicts prevailing scientific thought about what happens when animal species interbreed. view more (2007-09-27)
New malaria agent found in chimpanzees close to that commonly observed in humans
Researchers based in Gabon and France report the discovery of a new malaria agent infecting chimpanzees in Central Africa. view more (2009-05-29)
For two primates, patience takes different forms, shaped by ecology
Across the animal kingdom, individuals face choices between patience and impulsivity. A classic case, confronted by all animals-humans included-is that between a small, immediate food reward and a delayed, but larger, reward. view more (2005-10-25)
Evolutionary shifts in olfactory sensitivities in fruit flies
How do an animal's senses change as it evolves to occupy a new ecological niche? By comparing the olfactory system of the fruit fly Drosophila melanogaster, which feeds from multiple fruit types, with that of its sibling species D. sechellia, a specialist particularly drawn to a single fruit type. view more (2006-01-10)
Invasive species on the march: variable rates of spread set current limits to predictability
Whether for introduced muskrats in Europe or oak trees in the United Kingdom, zebra mussels in United States lakes or agricultural pests around the world, scientists have tried to find new ways of controlling invasive species by learning how these animals and plants take over in new environs. view more (2009-09-18)
New 150 Million-Year-Old Crab Species Discovered
Researchers from Kent State University and the University of Bucharest, Romania, have discovered a new primitive crab species Cycloprosopon dobrogea in eastern Romania. Previously unexamined, these ancient crabs from the Prosopidae family existed more than 150 million years ago during the Jurassic period. view more (2007-10-18)
Discarded human debris threatens global biodiversity
Discarded human debris is encouraging colonization of exotic marine animals in the world`s oceans and threatening global biodiversity, particularly in the Southern Ocean. The findings, reported in this week`s NATURE, are based on a 10-year study of human litter (mostly plastic) washed ashore on 30 remote islands around the globe, from the Arctic... view more...

The future of tropical forests
Deforestation and habitat loss are expected to lead to an extinction crisis among tropical forest species. Humans in rural settings contribute most to deforestation of extant tropical forests. view more (2006-04-07)
Mangrove-dependent animals globally threatened
More than 40 percent of a sample of amphibians, reptiles, mammals, and birds that are restricted to mangrove ecosystems are globally threatened with extinction, according to an assessment published in the July/August issue of BioScience. view more (2009-07-01)
