Conservation of freshwater fish biodiversity: a challenge for the countries of the South
Humans have regularly been introducing exotic species into natural environments in order to provide for their nutritional necessities or meet less indispensable purposes such as horticulture, fishing or hunting. view more (2008-03-27)
Scientists find mercury threatens next generation of loons
A long-term study by the Wildlife Conservation Society, the BioDiversity Research Institute, and other organizations has found and confirmed that environmental mercury-much of which comes from human-generated emissions-is impacting both the health and reproductive success of common loons in the Northeast. view more (2008-03-05)
Protea plants help unlock secrets of species 'hotspots'
New species of flowering plants called proteas are exploding onto the scene three times faster in parts of Australia and South Africa than anywhere else in the world, creating exceptional 'hotspots' of species richness, according to new research published today in Proceedings of the National Academy of Sciences (PNAS). view more (2008-12-23)
GM CROPS AND THE ENVIRONMENT
The Natural Environment Research Council (NERC), as well as other research bodies, is investigating possible impacts of GMOs on the environment. For some crops and for some types of genetic modification we have a clear understanding of the risks. For others, further work is needed to reduce uncertainty. view more (1999-02-22)
Weed resistance to glyphosate in genetically modified soybean cultivation in Argentina
The article written by Rosa Binimelis, Walter Pengue and Iliana Monterroso, is the product of collaborative work among the Autonomous University of Barcelona, University of Buenos Aires and the Latin American Faculty of Social Sciences in Guatemala. view more (2009-05-27)
Oklahoma researchers support biodiversity in biofuels production
U.S. and European mandates for subsidies of cellulosic ethanol production and use have uncertain environmental consequences according to an international group of scientists which includes researchers from the University of Oklahoma and Oklahoma State University. view more (2008-10-06)
New cost-benefit model will aid efforts to conserve wilderness: UBC researcher
A new conservation model that measures the value of ecosystem services benefiting humans - ranging from flood control to crop pollination - can foster more win-win solutions between wilderness advocates and landowners. view more (2006-10-31)
Biologists Produce Global Map of Plant Biodiversity
Biologists at the University of California, San Diego and the University of Bonn in Germany have produced a global map of estimated plant species richness. Covering several hundred thousand species, the scientists say their global map is the most extensive map of the distribution of biodiversity on Earth to date. view more (2007-03-21)
Brown Scientists Say Biodiversity Is Crucial to Ecosystem Productivity
In the first experiment involving a natural environment, scientists at Brown University have shown that richer plant diversity significantly enhances an ecosystem's productivity. view more (2008-04-25)
What makes life go at the tropics?
What causes tropical life to thrive: temperature, or sunlight? The answer is not necessarily "both." According to a study published online this week in PNAS Early Edition, the explosion of species at the tropics has much more to do with warmth than with light. view more (2008-05-28)
Smithsonian coral biodiversity survey of Panama's Pearl Islands
A comprehensive survey of coral biodiversity in Panama's Las Perlas Archipelago, published in the journal Environmental Conservation by researchers from the Smithsonian Tropical Research Institute and their colleagues, has resulted in clear conservation recommendations for a new coastal management plan. view more (2008-07-08)
Increased competition for pollen may lead to plant extinctions
The decline of birds, bees and other pollinators in the world's most diverse ecosystems may be putting plants in those areas at risk, according to new research. view more (2006-01-20)
Taking evolution's temperature: Researchers pinpoint the energy it takes to make a species
Writing this week in the Proceedings of the National Academy of Sciences, scientists say higher temperatures near the equator speed up the metabolisms of the inhabitants, fueling genetic changes that actually lead to the creation of new species. view more (2006-06-01)
Rainfall and river networks prove accurate predictors of fish biodiversity
Princeton researchers have invented a method for turning simple data about rainfall and river networks into accurate assessments of fish biodiversity, allowing better prediction of the effects of climate change and the ecological impact of man-made structures like dams. view more (2008-05-08)
Without ecology we are failing to reap the rewards of agri-environment schemes
Ecological evaluations must become an integral part of European agri-environment schemes if the billions of Euros spent on them are to result in real ecological benefits, leading ecologists have warned. A comprehensive review of the biodiversity benefits of agri-environment schemes, published in the latest issue of the British Ecological Society's... view more... (2003-12-04)
Global warming threatens tropical species, the ecosystem and its by-products
Tropical lizards detect the effects of global warming in a climate where the smallest change makes a big difference, according to herpetologist Laurie Vitt, curator of reptiles and George Lynn Cross Research Professor at the University of Oklahoma's Sam Noble Museum of Natural History view more (2009-08-26)
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)
Biodiversity passes the taste test and is healthier too
Cattle and sheep grazed on natural grasslands help maintain biodiversity and produce tastier, healthier meat, according to a study funded by the Economic and Social Research Council (ESRC). view more (2009-01-14)
Study of islands reveals surprising extinction results
It's no secret that humans are having a huge impact on the life cycles of plants and animals. UC Santa Barbara's Steven D. Gaines and fellow researcher Dov Sax decided to test that theory by studying the world's far-flung islands. view more (2008-08-27)
Dying frogs sign of a biodiversity crisis
Devastating declines of amphibian species around the world are a sign of a biodiversity disaster larger than just frogs, salamanders and their ilk, according to researchers from the University of California, Berkeley. view more (2008-08-13)
