Oceans turning to acid from rise in CO2
A report issued by the Royal Society in the U.K. sounds the alarm about the world's oceans. "If CO2 from human activities continues to rise, the oceans will become so acidic by 2100 it could threaten marine life in ways we can't anticipate," commented Dr. Ken Caldeira, co-author of the report and a newly appointed staff scientist at the... view more...

Diverse tropical forests defy metabolic ecology models
As global change accelerates, quantifying the role of forests in the carbon cycle becomes ever more urgent. Modelers seek simple predictors of forest biomass and carbon flux. view more (2006-04-24)
Surprising Killer of Southeastern Salt Marshes: Common Sea Snails
Periwinkles, the spiral-shelled snails commonly found along rocky U.S. shorelines, play a primary role in the unprecedented disappearance of salt marsh in the southeastern states, according to new research published in Science. view more (2005-12-16)
Wildlife researchers identify impacts of contamination in amphibians
Bill Hopkins, fisheries and wildlife associate professor in Virginia Tech's College of Natural Resources, and colleagues doing research at the Savannah River Ecology Laboratory and in the field, have demonstrated that amphibians are exposed to contaminants through maternal transfer, as has been proven for other vertebrates. view more (2006-02-22)
Alligator egg development at prehistoric oxygen levels
The development of bone structures in alligator eggs raised under varying oxygen concentrations creates a link to fossil records of the evolution of vertebrates and prehistoric atmospheric oxygen concentrations, according to a paper to be presented at the Earth System Processes 2 meeting in Alberta, Canada. view more (2005-08-05)
From parasitism to mutualism: Partner control in asymmetric interactions
What prevents an exploitative individual from taking advantage of a cooperative partner? Most attempts to answer this question focus on reciprocity - exploitation may not pay, if it triggers retaliation. But in many encounters, only one individual can exploit the other. For example, when coral reef fish approach a `cleaner` wrasse to have their... view more... (2002-09-09)
Recovery from acid rain 'much slower than expected'
Acid rain was one of the world's worst pollution problems of the 1970s and 1980s, affecting large areas of upland Britain, as well as Europe and North America. view more (2007-09-28)
Marine pathogens spread much faster than their terrestrial counterparts
It has become increasingly clear that pathogen epidemics are as significant a component of marine systems as they are in terrestrial systems. At an National Center for Ecological Analysis and Synthesis (NCEAS) working group on Diseases in the Ocean, McCallum, Harvell and Dobson collated data on epidemic spread from both terrestrial and marine... view more...

"Live fast, die young" applies to forests, too.
Forests provide humans with economically important and often irreplaceable products and services, and affect global climate by acting as sources and sinks of heat-trapping carbon dioxide. Yet the possible responses of forests to ongoing environmental changes are poorly understood. In the most recent issue of Ecology Letters, Stephenson and van... view more... (2005-04-19)
Sequencing our seas
Scientists have sequenced and compared the genomes of planktonic microbes living throughout the water column in the Pacific Ocean. view more (2006-01-30)
Scientific design of GM farm-scale evaluations made public
The 40th anniversary issue of the British Ecology Society's Journal of Applied Ecology this month leads with two major papers describing the background, methodology and experimental design of the farm-scale evaluations of genetically modified herbicide-tolerant crops. In laying out the statistical design and methods of data collection for the... view more... (2003-02-07)
Mean Population Size Increases with Diversity
A long-standing debate in ecology has been the effect of diversity on the temporal stability of biological systems. Ecological theory predicts that the stability of populations should decline as community diversity increases, in part, because population size is assumed to decline with community richness. In the February issue of Ecology Letters,... view more... (2003-01-28)
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)
Earth Rx: A microbial biotechnology prescription for global environmental health
Water. Waste. Energy. This trio of problems is among the greatest challenges to the environmental health of society. Water purification alone is becoming more problematic in the world due to our increasingly reliance on contaminated sources, such as polluted rivers, lakes and groundwater. view more (2006-02-16)
Improved estimates of population extinction risk (Harding and McNamara)
An important application of theoretical ecology is in estimation of species extinction risk. Extinction models guide the selection of management regimes for endangered species. Two vital parameters in these models are the mean population growth rate and its variance. However, empirical data on population growth are rarely perfect, but are... view more... (2003-12-10)
Biodiversity promotes evolutionary change
Evolutionary biologists at the University of East Anglia have discovered a new link between biodiversity and the evolution of new species. view more (2005-04-18)
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)
Yale journal examines the global impact of cities
The global impact of cities is the focus of cutting-edge research in a special issue of Yale's Journal of Industrial Ecology. view more (2007-06-18)
Underdogs in the understory: Study suggests nature favors rarer trees
A study of seven tropical forests around the world has revealed that nature encourages biodiversity by favoring the growth of less common trees. view more (2006-01-30)
University of Kent course run in partnership with modern wonder of the world
The news that Kew Gardens is to join the likes of the Taj Mahal and the Great Wall of China as a modern wonder of the world has been welcomed by teachers on the University of Kent's MSc Programme in Ethnobotany. Together with the Durrell Institute of Conservation and Ecology (DICE), the Department of Anthropology and the Royal Botanic Gardens... view more... (2003-07-11)
