11,000 alien species invade Europe
For the first time it is now possible to get a comprehensive overview of which alien species are present in Europe, their impacts and consequences for the environment and society.   view more (2008-11-21)

Alpine rivers hold important clues for preserving biodiversity and coping with climate change
Marginal plants, particularly trees, play a crucial role in sustaining the biodiversity of Europe's big river systems, according to a recently held workshop organised by the European Science Foundation (ESF).   view more (2008-11-18)

'Arid aquaculture' among livelihoods promoted to relieve worsening pressure on world's drylands
"Arid aquaculture" using ponds filled with salty, undrinkable water for fish production is one of several options experts have proven to be an effective potential alternative livelihood for people living in desertified parts of the world's expanding drylands.   view more (2008-11-11)

Overfishing threatens European bluefin tuna
Bluefin tuna disappeared from Danish waters in the 1960s. Now the species could become depleted throughout the northeast Atlantic and Mediterranean, according to analyses by the Technical University of Denmark (DTU Aqua) and University of New Hampshire. The species is highly valued as sushi.   view more (2008-11-07)

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)

EPA teams with National Geographic Society and World Resources Institute to map ecosystem services
The U.S. Environmental Protection Agency (EPA) is collaborating with the National Geographic Society and the World Resources Institute to develop tools that will help to fully account for the value of ecosystem services.   view more (2008-10-30)

Current mass extinction spurs major study of which plants to save
The Earth is in the midst of the sixth mass extinction of both plants and animals, with nearly 50 percent of all species disappearing, scientists say.   view more (2008-10-21)

When it comes to forest soil, wildfires pack 1-2 punch
For decades, scientists and resource managers have known that wildfires affect forest soils, evidenced, in part, by the erosion that often occurs after a fire kills vegetation and disrupts soil structure.   view more (2008-10-17)

UGA study reveals ecosystem-level consequences of frog extinctions
Streams that once sang with the croaks, chirps and ribbits of dozens of frog species have gone silent. They're victims of a fungus that's decimating amphibian populations worldwide.   view more (2008-10-17)

Brown Scientist Finds Coastal Dead Zones May Benefit Some Species
Coastal dead zones, an increasing concern to ecologists, the fishing industry and the public, may not be as devoid of life after all. A Brown scientist has found that dead zones do indeed support marine life, and that at least one commercially valuable clam actually benefits from oxygen-depleted... view more (2008-10-15)

Ecological restoration as a tool for reversing ecosystem fragmentation
Ecosystem fragmentation, along with many other global trends, is causing the natural world to undergo profound changes at all spatial scales from the micro-habitat to the continental.   view more (2008-10-09)

Beavers: Dam good for songbirds
The songbird has a friend in the beaver. According to a study by the Wildlife Conservation Society (WCS), the busy beaver's signature dams provide critical habitat for a variety of migratory songbirds, particularly in the semi-arid interior of the West.   view more (2008-10-09)

Decline in Alaskan sea otters affects bald eagles' diet
Sea otters are known as a keystone species, filling such an important niche in ocean communities that without them, entire ecosystems can collapse.   view more (2008-10-03)

Field of the future -- ecological experiment simulates conditions in 2100
A new experiment to find out how British plant ecosystems may be affected by future changes to climate and biodiversity is underway at Imperial College London.   view more (2008-09-29)

Seabird Ammonia Emissions Contribute to Atmospheric Acidity
Ammonia emissions from seabirds have been shown to be a significant source of nitrogen in remote coastal ecosystems, contributing to nutrient enrichment (eutrophication) and acidification in ecosystems.   view more (2008-09-23)

Cancer-causing gut bacteria exposed
Normal gut bacteria are thought to be involved in colon cancer but the exact mechanisms have remained unknown. Now, scientists from the USA have discovered that a molecule produced by a common gut bacterium activates signalling pathways that are associated with cancer cells.   view more (2008-09-22)

Old growth forests are valuable carbon sinks
Contrary to 40 years of conventional wisdom, a new analysis to be published Friday in the journal Nature suggests that old growth forests are usually "carbon sinks" - they continue to absorb carbon dioxide from the atmosphere and mitigate climate change for centuries.   view more (2008-09-11)

Thawing permafrost likely to boost global warming
The thawing of permafrost in northern latitudes, which greatly increases microbial decomposition of carbon compounds in soil, will dominate other effects of warming in the region and could become a major force promoting the release of carbon dioxide and thus further warming, according to a new... view more (2008-09-02)

Cell removal technique could lead to cheaper drugs
Researchers at the University of Edinburgh have pioneered a simple way to remove dead cells from cell cultures used to make protein-based drugs, which are increasingly prescribed to treat a range of illnesses.   view more (2008-08-27)

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)

Numerical simulations of nutrient transport changes in Honghu Lake Basin
The research by Gui Feng & Yu Ge showed the relative role of natural, climate-induced changes versus human-related activities in nutrient transportation changed over time.   view more (2008-08-20)

Microbes, by latitudes and altitudes, shed new light on life's diversity
Microbial biologists, including the University of Oregon's Jessica L. Green, may not have Jimmy Buffett's music from 1977 in mind, but they are changing attitudes about evolutionary diversity on Earth, from oceanic latitudes to mountainous altitudes.   view more (2008-08-12)

Actions of individuals key to saving biodiversity-and ourselves, Stanford biologists say
Even if you don't like the outdoors, you're probably pretty fond of air, clean water and food. That makes you a fan of biodiversity, because those essentials for life-human and otherwise-are maintained as a direct result of the Earth's biodiversity, the abundance and variety of species and... view more (2008-08-12)

Evaluating ecosystem services
Environmental conservation efforts have traditionally focused on protecting individual species or natural resources. Scientists are discovering, however, that preserving the benefits that whole ecosystems provide to people is more economically and environmentally valuable. At the Annual Meeting of... view more (2008-08-05)

Searching for shut eye: Penn study identifies possible sleep gene
While scientists and physicians know what happens if you don't get six to eight hours of shut-eye a night, investigators have long been puzzled about what controls the actual need for sleep. Researchers at the University of Pennsylvania School of Medicine might have an answer, at least in fruit... view more (2008-07-30)
