Ecologists use oceanographic data to predict future climate change
Ecologists and oceanographers are attempting to predict the future impacts of climate change by reconstructing the past behavior of Arctic climate and ocean circulation. view more (2008-11-07)
"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)
Spreading antibiotics in the soil affects microbial ecosystems
Antibiotics used extensively in intensive livestock production may be having an adverse effect on agricultural soil ecosystems. view more (2009-03-30)
New study finds that some plants can adapt to widespread climate change
While many plant species move to a new location or go extinct as a result of climate change, grasslands clinging to a steep, rocky dale-side in Northern England seem to defy the odds and adapt to long-term changes in temperature and rainfall. view more (2008-07-09)
Burning wetlands unleash sequestered mercury in wake of climate change
Climate change appears to be contributing to the waking of a dangerous sleeping giant in the most northern wetlands of North America - mercury. view more (2006-08-22)
Thawing permafrost increases greenhouse gas emission from subarctic mires
The permafrost in the mires of subarctic Sweden is undergoing dramatic changes. The part of the soils that thaws in the summer, the so-called active layer, has become deeper since 1970 and the permafrost has disappeared altogether in some locations. This has lead to significant changes in the vegetation composition and subsequent increase in... view more... (2004-02-24)
Marine researchers explore sediment highways
A European team of researchers has demonstrated that sediment is transported to the deep sea via canyons in the seabed. The sediment accumulates in the head of the submarine canyons. At the end of the canyons, mud avalanches disperse into the deep sea. Scientists from the Netherlands Institute for Sea Research (NIOZ) presented their findings at an... view more... (2002-04-18)
Modest fisheries reduction could protect vast coastal ecosystems: UBC research
A reduction of as little as five per cent in fisheries catch could result in as much as 30 per cent of the British Columbia coastal ecosystems being protected from overfishing, according to a new study from the UBC Fisheries Centre. view more (2009-07-22)
Peat and forests save permafrost from melting
Permafrost may be buffered against the impacts of climate change by peat and vegetation present in the northern regions, according to a study by McMaster researchers. view more (2007-09-14)
Overfishing puts Southern California kelp forest ecosystems at risk, report scientists
Kelp forest ecosystems that span the West Coast -- from Alaska to Mexico's Baja Peninsula -- are at greater risk from overfishing than from the effects of run-off from fertilizers or sewage on the shore. view more (2006-05-26)
The dawn of deep ocean mining
We're on the brink of the era of deep ocean mining, says a global pioneer in the study of sea floor mineral deposits. view more (2006-02-21)
Urban water ecology at the ESA annual meeting
Increasingly, human urban development overlaps with habitat for wild animals and plants, creating environments that degrade natural landscapes. view more (2009-08-03)
McGill researchers find oldest rocks on Earth
McGill University researchers have discovered the oldest rocks on Earth - a discovery which sheds more light on our planet's mysterious beginnings. view more (2008-09-26)
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)
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)
Ume'å researchers have mapped the dams of the world
More than half of the world's large rivers are fragmented and regulated by dams. The largest and the most biologically and geographically diverse rivers are all affected. This is shown by a global study that is published in this week's issue of the journal Science. view more (2005-04-14)
As terrestrial telecoms dial into satellite networks
Improving the integration of satellite networks with more traditional terrestrial telephone infrastructures, will help next generation telephony move from concept towards reality. view more (2006-01-17)
Beaver dams create healthy downstream ecosystems
Beavers, long known for their beneficial effects on the environment near their dams, are also critical to maintaining healthy ecosystems downstream. view more (2006-06-06)
First Biodiversity Census of coral reef ecosystems in the NW Hawaiian Islands
As part of the international Census of Marine Life (CoML), a team of world renown scientists will embark on an expedition to explore coral reef biodiversity in the largest fully protected marine area in the world-the Northwestern Hawaiian Islands Marine National Monument. view more (2006-10-11)
A plan for reintroducing megafauna to North America
Dozens of megafauna (large animals over 100 pounds) - such as giant tortoises, horses, elephants, and cheetah - went extinct in North America13,000 years ago during the end of the Pleistocene. view more (2006-10-03)
