Challenges of HIV-1 subtype diversity
A review article in the New England Journal of Medicine explores the genetic variation of HIV-1 and its implications for preventing and treating the disease. Francine McCutchan, Ph.D., a researcher with the U.S. Military HIV Research Program, co-authored the article, which appeared in the April 10, 2008 edition. view more (2008-05-22)
New method for measuring biodiversity
German and Sri Lankan researchers have developed a new method for measuring the impacts of species on local biodiversity. It makes it possible to determine whether a certain species promotes or suppresses species diversity. view more (2008-02-19)
Underestimation of frog numbers causes concern
Frogs are vanishing from all the world's ecosystems with unprecedented speed. It is thought that more than 100 species have died out since 1980 alone. view more (2007-10-31)
Imaging from space protects natural habitats
The method for remote designing of conserved natural territories has been developed by Russian researchers from the Severtsov Institute of Ecology and Evolution Problems, Russian Academy of Sciences, and the Faculty of Geography, Moscow State University, supported by WWF. The method was applied to the territories of the Far East, mountains of the... view more... (2003-11-06)
The Sweet World of Soil Microbiology
Using classroom, hands-on activities can help instructors to communicate difficult scientific concepts and stimulate student thinking. Despite its importance, the diversity in soil microbes can conceptually be difficult to teach, especially in natural resource classrooms composed primarily of undergraduates who have had little exposure to... view more...

'Colorblindness' hurts minority employees, but multiculturalism inspires their commitment
A new study by psychologists at the University of Georgia shows for the first time that whites' beliefs about diversity can hurt or help their minority peers. view more (2009-03-19)
Symbiotic fungi promote invasion into diverse plant communities (Rudgers et al.)
The biodiversity of a community can affect its functional properties, such as its productiveness or its ability to resist invasion by exotic species. Many grass species host fungi in their leaves that can render them more resistant to herbivory, drought, and competition. In a forthcoming issue of Ecology Letters, Rudgers, Koslow and Clay... view more... (2003-12-10)
African village dogs are genetically much more diverse than modern breeds
African village dogs are not a mixture of modern breeds but have directly descended from an ancestral pool of indigenous dogs, according to a Cornell-led genetic analysis of hundreds of semi-feral African village dogs. view more (2009-08-05)
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)
Alternative agricultural practices combine productivity and soil health
The progressive degradation of useful soils for agriculture and farm animal husbandry is a growing environmental and social problem, given that it endangers the food safety of an increasing world population. view more (2009-07-27)
Ethnicity affects timing and access to cardiac care
Ethnicity is having a significant impact on timely access to cardiac care in Calgary and likely across Canada as the population's ethnic diversity grows, according to new research led by a team from the University of Calgary. view more (2009-05-06)
Woods Hole Research Center scientists using remote sensing tools to predict bird species richness
Scientists at the Woods Hole Research Center, NASA Goddard Space Flight Center and the University of Maryland have taken a novel approach to studying biological diversity by making use of laser remote sensing (lidar). view more (2007-05-15)
Study reveals predation-evolution link
The fossil record seems to indicate that the diversity of marine creatures increased and decreased over hundreds of millions of years in step with predator-prey encounters, Virginia Tech geoscientists report in the Proceedings of the National Academy of Science. view more (2007-09-11)
Lack of funding for world crop diversity threatens sustainable food supply
Researchers from the Department of Agricultural Sciences at Imperial College have warned that a large proportion of the world's collection of crop diversity could be lost due to a lack of funding for the "genebanks" in which they are stored. In a report launched today at the United Nations World Summit on Sustainable Development,... view more... (2002-08-28)
Immune genes adapt to parasites
Thank parasites for making some of our immune proteins into the inflammatory defenders they are today. view more (2009-05-26)
Rare disorder gives modelers first glimpse at immune system development
Children born without thymus glands have given Duke University Medical Center researchers a rare opportunity to watch as a new immune system develops its population of infection-fighting T-cells. view more (2009-06-17)
Remote sheep population resists genetic drift
A whimsical attempt to establish a herd of mouflon for sport hunting on a remote island in the Indian Ocean 50 years ago has inadvertently created a laboratory for genetic researchers and led to a surprising discovery. view more (2007-03-12)
Darwin and the world's first ecological experiment
Scientists examining the work that influenced Charles Darwin have rediscovered the details of what may be the world's first ecological experiment. Darwin, in his Origin of Species of 1859, referred to an experiment investigating the biology of grassland plants that showed how a greater diversity of grasses planted in experimental plots was... view more...

Study suggests past climate changes may have promoted the formation of new species in the Amazon
The results of a new study suggest that past climate changes and sea level fluctuations may have promoted the formation of new species in the Amazon region of South America. view more (2008-07-23)
New study finds biodiversity conservation secures ecosystem services for people
Healthy ecosystems that provide people with essential natural goods and services often overlap with regions rich in biological diversity, underscoring that conserving one also protects the other, according to a new study. view more (2007-12-06)
