Study provides new understanding of spontaneous hybridization
Plant and animal breeders have long used hybridization to transfer useful traits between species. view more (2006-05-11)
Researchers go underground to reveal 850 new species
Australian researchers have discovered a huge number of new species of invertebrate animals living in underground water, caves and "micro-caverns" amid the harsh conditions of the Australian outback. view more (2009-09-28)
Mammals that hibernate or burrow less likely to go extinct
The best way to survive the ill-effects of climate change and pollution may be to simply sleep through it. view more (2009-01-29)
Diversity in the deep blue seas
Nature magazine has published an article by Xabier Irigoien, a researcher at AZTI, the Basque Fisheries and Marine Technological Research Centre. The article provides data on the diversity of marine life at the bottom of the sea - particularly amongst algae. Species diversity Most research carried out on the diversity of species has been with land... view more... (2004-06-28)
Lionfish decimating tropical fish populations, threaten coral reefs
The invasion of predatory lionfish in the Caribbean region poses yet another major threat there to coral reef ecosystems - a new study has found that within a short period after the entry of lionfish into an area, the survival of other reef fishes is slashed by about 80 percent. view more (2008-07-21)
Giant panda can survive
The giant panda is not at an "evolutionary dead end" and could have a long term viable future, according to new research involving scientists from Cardiff University. view more (2007-08-27)
Theory of oscillations may explain biological mysteries
New mathematical studies of the interactions between oscillating biological populations may shed light on some of the toughest questions in ecology, including the number and types of species in an ecosystem, according to an article in the December 2006 issue of BioScience. view more (2006-12-04)
Climate change opens new avenue for spread of invasive plants
Plants that range northward because of climate change may be better at defending themselves against local enemies than native plants. view more (2008-11-20)
Avian Persistence in Fragmented Rainforest
Loss and deterioraton of indigenous habitat increasingly affect natural populations worldwide. As a result of these processes, new selection pressures are imposed upon organisms, increasing local extinction rates. Simultaneously, reduced movement among remnant patches lowers colonisation rates and affects demographic and genetic population... view more... (2002-11-08)
Direct link established between tropical tree and insect diversity
Higher tree species diversity leads directly to higher diversity of leaf-eating insects. view more (2006-07-19)
What determines the speed at which birds fly?
Aerodynamic scaling rules that explain how flight varies according to weight and wing loading have been used to compare general speeds of a wide range of flyers, from the smallest insects to the largest aircraft. view more (2007-07-17)
1 moose, 2 moose: Scientist seeks correction in number of species
It is a misinterpretation of the application of the bedrock of scientific naming with regard to the number of moose species that Kris Hundertmark, a University of Alaska Fairbanks wildlife geneticist at the Institute of Arctic Biology, seeks to correct. view more (2009-06-15)
When fish become extinct, the cycling of critical nutrients in ecosystems changes, Cornell study finds
Ecosystems are such intricate webs of connections that few studies have been able to explore exactly what happens when a species dies out. view more (2007-03-05)
Biological invasions can begin with just 1 insect
A new study by York University biologists Amro Zayed and Laurence Packer has shown that a lone insect can initiate a biological invasion. view more (2007-09-12)
Islands spark accelerated evolution
The notion of islands as natural test beds of evolution is nearly as old as the theory itself. The restricted scale, isolation, and sharp boundaries of islands create unique selective pressures, often to dramatic effect. view more (2006-09-12)
When Hosts Go Extinct, What Happens to Their Parasites?
Hands wring and teeth gnash over the loss of endangered species like the panda or the polar bear. But what happens to the parasites hosted by endangered species? view more (2009-06-02)
Reliance on unverifiable observations hinders successful conservation of wildlife species
Nearly any evidence of the occurrence of a rare or elusive wildlife species has the tendency to generate a stir. Case in point: in February 2008, remote cameras unexpectedly captured the images of a wolverine in the central Sierra Nevada, an area from which the species was believed to be extinct since 1922. view more (2008-06-23)
Indigenous water frogs under threat
Indigenous water frogs can be crowded out by immigrant or imported species. This is the finding of a Franco-German study. The scientists investigated water frog populations in France and Northern Spain and noticed that the marsh frog (Rana ridibunda), which normally occurs only in Eastern Europe, has the potential to crowd out indigenous species... view more...

Mixed dolphins and the impact of tourism
Dolphins off the coast of East Africa are exposed to a number of threats, like indirect catching, hunting, and environmental impact. In her dissertation at the Department of Zoology, Stockholm University, Sweden, Eva Stensland has studied behavioral ecology in Indo-Pacific bottlenose and humpback dolphins, off Zanzibar, Tanzania. For the last... view more... (2004-05-07)
Global map shows new patterns of extinction risk
The most detailed world map of mammals, birds and amphibians ever produced shows that endangered species from these groups do not inhabit the same geographical areas, says new research published today. view more (2006-11-02)
