When fish become extinct, the cycling of critical nutrients in ecosystems changes, Cornell study finds
Ecosystems are such intricate webs of connections that few studies have been able to explore exactly what happens when a species dies out. view more (2007-03-05)
Climate change may spell demise of key salt marsh constituent
Global warming may exact a toll on salt marshes in New England, but new research shows that one key constituent of marshes may be especially endangered. view more (2009-07-13)
New paper examines dams' effects on California salmon
Spring-run Chinook salmon and other fish in the rivers of California's Central Valley could be harmed by more water-storage dams, according to researchers at Duke University and the National Oceanic and Atmospheric Administration. view more (2007-09-25)
Planning for stewardship an important part of successful ecological restoration
Restoring degraded ecosystems around Seattle — and giving them a fighting chance to stay healthy — can be as much about PR as the right plants. That's what students learn through the University of Washington's Restoration Ecology Network, a program of teaching and research recognized nationally in this week's issue of Science magazine. view more (2006-06-30)
Social life-history response to individual immune challenge of workers of Bombus terrestris: a possible new cooperative phenomenon
Solitary organisms can minimise fitness loss from parasitism with a facultative change to an earlier reproduction. Such a shift of the reproductive effort gives the host a chance to compensate for the cost on future reproduction resulting from the infection. In the case of social insects, where brood care and reproductive effort are shared between... view more... (2004-02-05)
Regional warming-induced species shift in NW Mediterranean marine caves
The north-western Mediterranean Sea has a high biodiversity reflecting a mixture of temperate and subtropical species. But this basin already shows signs of large-scale warming. Marine cave communities with endemic and specialised species are particularly at risk since they are naturally fragmented and more sensitive to perturbations. In the... view more... (2003-04-08)
Size does matter when choosing a mate
The difference in size between males and females of the same species is all down to the battle for a mate, according to a study of shorebirds published by British scientists today (August 9 2004). The findings, published in the Proceedings of the National Academy of Sciences, are the first explanation for a rule identified over forty years ago by... view more... (2004-08-09)
Manipulating biotope space can enhance beneficial biodiversity effects
Using diverse plant mixtures instead of monocultures can increase yield and other ecosystem goods and services on which humans depend. Recent studies showed that such beneficial effects of biodiversity depend on complementarity between species in resource use, as is the case if species root in different soil depths. This knowledge led to the... view more... (2004-06-10)
Finnish Centre of Exellence in Virus Research
The Finnish Center of Excellence (CoE) in Virus Research was selected as a member of the National Centers of Excellence Program by the Academy of Finland for the years 2006-2011. view more (2006-06-22)
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)
Tropical forests leak nitrogen back into atmosphere, say scientists
In findings that could influence our understanding of climate change, a Princeton research team has learned that tropical forests return to the atmosphere up to half the nitrogen they receive each year, thanks to a particular type of bacteria that lives in those forests. view more (2006-05-23)
Turtles indeed in danger
Even though many sea turtle populations are declining, quantifying factors that contribute to declines has been challenging. Mortality occurs on nesting beaches due to habitat loss, egg poaching, and predation. But turtles also die at sea due to accidental catches in fishing gear. In the March issue of Ecology Letters, Duke University researchers... view more... (2004-02-25)
Deep-sea Ecosystem Engineers
Tube worms living at deep-sea oil seeps in the Gulf of Mexico significantly alter their habitat, similar to beavers altering the flow of a river. Researchers from Pennsylvania State University have just published an important finding in the journal Ecology Letters. A computer model of tube worm aggregations was created for Lamellibrachia luymesi,... view more... (2003-03-12)
Abandoned farmlands are key to sustainable bioenergy
Biofuels can be a sustainable part of the world's energy future, especially if bioenergy agriculture is developed on currently abandoned or degraded agricultural lands, report scientists from the Carnegie Institution and Stanford University. view more (2008-06-24)
The Mediterranean connection: ecological effects of El Ni'ħo in the Northern hemisphere
The North Atlantic Oscillation (NAO) and the El Ni'ħo/Southern Oscillation (ENSO) are being increasingly acknowledged as major climatic sources of ecological variability. However, studies linking ecological processes to those oscillations have been conducted in geographic regions close to their centers of action, so their effects outside these... view more...

Odd energy mechanism in bacteria analyzed
Scientists at Oregon State University have successfully cultured in a laboratory a microorganism with a gene for an alternate form of photochemistry - an advance that may ultimately help shed light on the ecology of the world's oceans. view more (2005-11-04)
Nutrient pollution can exacerbate coral disease outbreaks and threatens coral reef health
Wildlife diseases are one of the primary threats to coral reefs and other endangered marine ecosystems. For example, fungal and bacterial infections of reef-building corals and other key species recently caused mass-mortalities throughout the Caribbean. Species that dominated Caribbean coral reefs only twenty years ago are now functionally... view more... (2003-11-24)
Wolves lose their predatory edge in mid-life, new U of Minnesota study shows
Although most wolves in Yellowstone National Park live to be nearly six years old, their ability to kill prey peaks when they are two to three, according to a study led by Dan MacNulty and recently published online by Ecology Letters. view more (2009-10-27)
New CU-Boulder study shows diversity decreases chances of parasitic disease
A new University of Colorado at Boulder study showing that American toads who pal around with gray tree frogs reduce their chances of parasitic infections known to cause limb malformations has strong implications for the benefits of biodiversity on emerging wildlife diseases. view more (2008-10-22)
Carbon turns over much faster through basal food-chain levels in aquatic than in terrestrial ecosystems
Global temperatures have increased dramatically over the past century, which is causing major impacts on climate patterns, ocean circulation and wildlife preservation. The increase in temperature is largely due to a rise of anthropogenic emissions of greenhouse gases, of which CO2 is one of the most important. To understand the capacity of... view more...
