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)
Climate change and permafrost thaw alter greenhouse gas emissions in northern wetlands
Permafrost - the perpetually frozen foundation of North America - isn't so permanent anymore, and scientists are scrambling to understand the pros and cons when terra firma goes soft. view more (2007-08-10)
Sudden collapse in ancient biodiversity: Was global warming the culprit?
Scientists have unearthed striking evidence for a sudden ancient collapse in plant biodiversity. A trove of 200 million-year-old fossil leaves collected in East Greenland tells the story, carrying its message across time to us today. view more (2009-06-19)
A link between greenhouse gases and the evolution of C4 grasses
How a changing climate can affect ecosystems is an important and timely question, especially considering the recent global rise in greenhouse gases. view more (2007-12-21)
Departure to cold water corals and other 'hot spots'
The research vessel, Polarstern leaves Bremerhaven for its 22nd Arctic expedition with a new shine, to begin its first work in the International polar year. view more (2007-05-25)
In the warming West, climate most significant factor in fanning wildfires' flames
The recent increase in area burned by wildfires in the Western United States is a product not of higher temperatures or longer fire seasons alone, but a complex relationship between climate and fuels that varies among different ecosystems. view more (2009-06-26)
New report says human tampering threatens planet's life-sustaining surface
In a report released today, scientists call for a new systematic study of the Earth's "critical zone"-the life-sustaining outermost surface of the planet, from the vegetation canopy to groundwater and everything in between.Understanding and predicting responses to global and regional change is necessary, they say, to mitigate the impacts... 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)
The Arctic and Global Warming
A warmer Arctic Ocean may mean less food for the birds, fish, and baleen whales and be a significant detriment to that fragile and interconnected polar ecosystem, and that doesn't bode well for other ocean ecosystems in the future. view more (2006-02-21)
New method for measuring biodiversity
German and Sri Lankan researchers have developed a new method for measuring the impacts of species on local biodiversity. It makes it possible to determine whether a certain species promotes or suppresses species diversity. view more (2008-02-19)
Decades of accumulated change court ecosystem catastrophe
Subjected to decades of gradual change by humans, many of the world’s natural ecosystems – from coral reefs and tropical forests to northern lakes and forests – appear susceptible to sudden catastrophic ecological change, an international consortium of scientists reports Thursday October 11 in the journal Nature. “Models... view more...

Long-term recovery of reefs from bleaching requires local action to increase resilience
In the journal Estuarine, Coastal and Shelf Science, University of Miami Rosenstiel School of Marine and Atmospheric Science Professor Dr. Peter Glynn, and 2008 Pew Fellow for Marine Conservation and Assistant Professor Dr. Andrew Baker, assess more than 25 years of data on reef ecosystems recovery from climate change-related episodes of coral... view more...

Major international study warns global warming is destroying coral reefs and calls for 'drastic actions'
If world leaders do not immediately engage in a race against time to save the Earth's coral reefs, these vital ecosystems will not survive the global warming and acidification predicted for later this century. That is the conclusion of a group of marine scientists from around the world in a major new study published in the journal Science on Dec.... view more... (2007-12-26)
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)
Recovering from a mass extinction
The full recovery of ecological systems, following the most devastating extinction event of all time, took at least 30 million years, according to new research from the University of Bristol. view more (2008-01-21)
On the volcano island Krakatau: regeneration of rain forest goes hand in hand with genetic diversity
Rain-forest trees colonizing a new piece of land contain a large genetic diversity. The Indonesian island Krakatau is a good natural test case for disrupted tropical rain forest. Here, fig species hybridise unexpectedly. A lesson for the future of nature reserves. Just today, May 13, Tracey Parrish of the Netherlands Institute of Ecology... view more... (2002-05-13)
Study shows genetically engineered corn could affect aquatic ecosystems
A study by an Indiana University environmental science professor and several colleagues suggests a widely planted variety of genetically engineered corn has the potential to harm aquatic ecosystems. The study is being published online this week by the journal Proceedings of the National Academies of Sciences. view more (2007-10-09)
Darwin and the world's first ecological experiment
Scientists examining the work that influenced Charles Darwin have rediscovered the details of what may be the world's first ecological experiment. Darwin, in his Origin of Species of 1859, referred to an experiment investigating the biology of grassland plants that showed how a greater diversity of grasses planted in experimental plots was... view more...

Air monitoring helps anticipate possible ecosystem changes
When rain settles the atmosphere and brings air pollutants to the ground, it can have a lasting effect on ecosystems, sometimes hundreds of miles away, according to a Texas AgriLife Research agricultural engineer. view more (2008-06-26)
Decline of world's estuaries and coastal seas
Human activity over the centuries has depleted 90% of marine species, eliminated 65% of seagrass and wetland habitat, degraded water quality 10-1,000 fold, and accelerated species invasions in 12 major estuaries and coastal seas around the world. view more (2006-06-23)
