Diversity of trees in Ecuador's Amazon rainforest defies simple explanation
Trees in a hyper-diverse tropical rainforest interact with each other and their environment to create and maintain diversity, researchers report in the Oct. 24 issue of the journal Science. view more (2008-10-24)
Identifying Mega-Targets for High-Yield Plant Breeding
Promoting genetic diversity in crops is traditional practice for agriculture professionals, and with today's technology, scientists are able to develop breeding programs with great care for the security of crops. This is particularly important due to the numerous risks the world's food supplies face with the changing climate. view more (2009-02-17)
Emphasis on conifer forests places multiple species at risk
The traditional emphasis on dense, fast-growing, conifer-dominated forests in the Pacific Northwest raises questions about the health of dozens of animal species that depend on shrubs, herbs and broad-leaf trees, a new analysis by Oregon State University and the U.S. Geological Survey suggests. view more (2007-08-24)
Seeing the forest and the trees
With human emissions of carbon dioxide on the rise, there is growing interest in maintaining the Earth's natural mechanisms that absorb and store carbon. view more (2005-10-24)
Coffee cultivation good for diversity in agrarian settlements but not in forests
Coffee shrubs, both in themselves and because they are most often cultivated in the shade of large trees, can have a positive impact on plant and animal diversity in those parts of the landscape that are deforested and dominated by agriculture. view more (2009-02-19)
Climate change could trigger 'boom and bust' population cycles leading to extinction
Climate change could trigger "boom and bust" population cycles that make animal species more vulnerable to extinction. , according to Christopher C. Wilmers, an assistant professor of environmental studies at the University of California, Santa Cruz. view more (2007-04-17)
Introduced marine species get larger in the invaded region
The transport of species outside their native region through human activities has often had a dramatic impact on the ecosystems into which these species are introduced and on the surrounding economies. The consequences of introduction for the introduced species itself, including changes in body size and shape, are less recognized. Prior studies of... view more... (2003-08-13)
Misclassified for centuries, medicinal leeches found to be 3 distinct species
Genetic research has revealed that commercially available medicinal leeches used around the world in biomedical research and postoperative care have been misclassified for centuries. view more (2007-04-12)
New Maize Map to Aid Plant Breeding Efforts
In a massive survey of genetic diversity in maize, also known as corn, researchers across the United States, have developed a gene map that should pave the way to significant improvements in a plant that is a major source of food, fuel, animal feed and fiber around the world. view more (2009-11-20)
The lost genetic legacy of American gray wolves
A new study undertaken by researchers at UCLA, Uppsala University and National Museum of Natural History, Smithsonian Institution and published in the journal Molecular Ecology, suggests that plans to reintroduce American gray wolves to the Western US will not restore the population to the near same extent of genetic diversity it originally... view more...

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)
All species are not created equal when assessing the impacts of species loss on ecosystems
Numerous studies have shown that when species are randomly lost from communities, ecosystem function declines. But such patterns of species loss do not reflect those in natural communities where major drivers of change, such as stress and disturbance, cause preferential loss of rare and uncommon species. In the June issue of Ecology Letters, Smith... view more... (2003-05-22)
ESA launches new project to protect biodiversity
The world's biodiversity is vanishing at an unprecedented rate - around 100 species every day - due to factors such as land use change and pollution. view more (2007-01-10)
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)
New research finds surveys of larval-stage organisms effective for measuring marine biodiversity
There is a push to document the biodiversity of the world within 25 years. However, the magnitude of this challenge is not well known, especially when it comes to vast and often inaccessible marine environments. view more (2006-05-15)
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)
Underdogs in the understory: Study suggests nature favors rarer trees
A study of seven tropical forests around the world has revealed that nature encourages biodiversity by favoring the growth of less common trees. view more (2006-01-30)
Coral reef fish harbor an unexpectedly high biodiversity of parasites
IRD researchers showed that Epinephilus maculates, a fairly abundant species of grouper off New Caledonia, was parasitized by 12 species of microscopic monogenean worms. view more (2007-09-06)
Dramatic shift from simple to complex marine ecosystems occurred 250M years ago at mass extinction
The earth experienced its biggest mass extinction about 250 million years ago, an event that wiped out an estimated 95% of marine species and 70% of land species. New research shows that this mass extinction did more than eliminate species: it fundamentally changed the basic ecology of the world's oceans. view more (2006-11-27)
