Seed banks preserve plant diversity
'Some seed gene banks contain more higher plant species per square meter than anywhere else on the planet', write Simon Linington and colleagues of the Millenium Seed Bank, Kew, in the October issue of Biologist. This helps to 'ensure plant diversity is available long term for use in development or habitat restoration', they explain. Although... view more... (2003-10-02)
New modeling study forecasts disappearance of existing climate zones
A new climate modeling study forecasts the complete disappearance of several existing climates in tropical highlands and regions near the poles, while large swaths of the tropics and subtropics may develop new climates unlike any seen today. view more (2007-03-28)
Mercury contamination of fish warrants worldwide public warning
The health risks posed by mercury contaminated fish is sufficient to warrant issuing a worldwide general warning to the public — especially children and women of childbearing age-to be careful about how much and which fish they eat. view more (2007-03-08)
Lowly Icelandic midges reveal ecosystem's tipping points
The midges that periodically swarm by the billions from Iceland's Lake Myvatn are a force of nature. view more (2008-03-06)
Warming climate may cause arctic tundra to burn
Research from ancient sediment cores indicates that a warming climate could make the world's arctic tundra far more susceptible to fires than previously thought. view more (2008-03-05)
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)
Dead clams tell many tales
Inventories of living and dead organisms could serve as a relatively fast, simple and inexpensive preliminary means of assessing human impact on ecosystems. view more (2007-10-30)
Study of Tropical Forests Worldwide Reveals that Nature Encourages Diversity
An analysis of seven tropical forests around the world has found that nature encourages diversity by selecting for less common trees as the trees mature. view more (2006-01-27)
Scientists warn that species extinction could reduce productivity of plants on Earth by half
An international team of scientists has published a new analysis showing that as plant species around the world go extinct, natural habitats become less productive and contain fewer total plants -- a situation that could ultimately compromise important benefits that humans get from nature. view more (2007-11-06)
Report Warns about Carbon Dioxide Threats to Marine Life
Worldwide emissions of carbon dioxide from fossil fuel burning are dramatically altering ocean chemistry and threatening marine organisms, including corals, that secrete skeletal structures and support oceanic biodiversity. view more (2006-07-06)
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)
Nile Delta fishery grows dramatically thanks to run-off of sewage, fertilizers
While many of the world's fisheries are in serious decline, the coastal Mediterranean fishery off the Nile Delta has expanded dramatically since the 1980s. view more (2009-01-20)
Ecosystem consequences of a single, genetically based plant trait
Climate is often touted as the most important regulator of decomposition and nutrient cycling processes in forest ecosystems, however, in the forthcoming issue of Ecology Letters, Schweitzer and her research team from Northern Arizona University and the University of Wisconsin, USA, demonstrate that plant genes can have strong effects on the... view more...

"Facts needed, not just opinions": Risk assessment research initiated to determine effects of genetically modified plants on soil ecosystems
Do genetically modified plants present a risk to the environment? "Most of the arguments used both in support and against the use of genetically modified crops to date have not been based upon facts, but rather emotion," claims George Kowalchuk of the Netherlands Institute of Ecology (NIOO-KNAW). The NIOO is now trying to gather the... view more... (2001-06-11)
Does climate change affect marine productivity?
The scientific magazine NATURE, a worldwide leader, has published an article of a research worker of the Basque foundation AZTI, Xabier Irigoien, about marine ecosystem. The prestigious scientific magazine NATURE has published in its last issue of September an article and cover, whose first author is the research worker of the Basque foundation... view more...

Trees to offset the carbon footprint?
How effective are new trees in offsetting the carbon footprint? A new study suggests that the location of the new trees is an important factor when considering such carbon offset projects. Planting and preserving forests in the tropics is more likely to slow down global warming. view more (2007-04-10)
A recipe for saving the world's oceans from an extinction crisis
Jeremy Jackson, senior scientist emeritus of the Smithsonian Tropical Research Institute and the Scripps Institution of Oceanography, asserts in the Aug. 12 issue of the journal Proceedings of the National Academy of Sciences, that the following steps, if taken immediately, could reverse the demise of the oceans: Establish marine reserves, enforce... view more...

Will lemmings fall off climate change cliff?
Contrary to popular belief, lemmings do not commit mass suicide by leaping off of cliffs into the sea. In fact, they are quite fond of staying alive. view more (2007-04-23)
Fighting pollution by forecasting the future
EUREKA project E! 2634 EUROENVIRON TEAP (Tool Evaluating Air quality impact of air Pollution) has created a real-time software solution to provide pollution forecasts for industrial plants, cities and air quality authorities. It will change the way pollution is dealt with and is set to increase the lead partner's turnover by 25%. view more (2004-11-02)
The conservation lens
The definition of conservation priorities for biodiversity often focuses only on the numbers of vertebrate animals and seed plants in the northern hemisphere or in the tropics. view more (2007-10-25)
