New study explores beetle species with two forms of females
A fascinating new study from the forthcoming issue of The American Naturalist attempts to explain the mysterious persistence of two forms of females in many diving beetle populations. view more (2006-01-25)
Reservoirs may accelerate the spread of invasive aquatic species, researchers say
Just as disturbance makes a landscape susceptible to invasion by alien plant species, the construction of reservoirs around the globe could be contributing to the accelerating spread of exotic aquatic species. view more (2005-05-31)
NYU scientists identify how development of different species uses same genes with distinct features
Biologists at New York University have identified how different species use common genes to control their early development and alter how these genes are used to accommodate their own features. view more (2007-04-02)
Thieves promote stable coexistence among desert rodents
The warm deserts of North America are hopping with multiple species of kangaroo rats and pocket mice despite limited seed resources. view more (2006-07-27)
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)
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)
Protecting Natural Spaces Does Not Prevent Invasion by Foreign Species
A study carried out by researchers at the Universitat Autònoma de Barcelonashows that protecting natural spaces does not prevent invasion by foreign vegetation species. Montserrat Vil' and Jordi Pujadas, researchers at the CREAF, have published the study, the first to quantify the relationship between species invasions and human activity... view more... (2002-02-27)
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)
Woody and aquatic plants pose greatest invasive threat to China
Although China currently has fewer invasive woody plants than the United States, China's potential for invasion by nonnative trees and shrubs is high, according to an article in the May 2008 issue of BioScience. view more (2008-05-01)
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)
