Putting ecology back into river restoration

An ambitious plan is under way in the ecological community to agree a set of standards for ecologically successful river restoration. The plan is being led by the British Ecological Society's Journal of Applied Ecology, which this month is publishing a special profile on river restoration. Opening the debate is a paper by 22 leading US river ecologists proposing five criteria for ecologically suc...

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. Over the last decade, the theory of metabolic ecology generated testable explanations, derived from physical and biochemical principles, for a wide range of ecological patterns. However, in two Ecology Letters articles, Hele...

UMaine teams with fishermen to study affects of trawling on seafloor ecology

Working in cooperation with Maine trawler captain Cameron McLellan and the Gulf of Maine Research Institute, UMaine graduate student Emily Knight and UMaine Marine Science professor Les Watling recently completed a long-term study that examines the effects of groundfish trawling on the complex ecology of the sea floor in the Gulf of Maine. Based on the gradual increases in complexity and d...

Amber reveals ecology of 30 million year old spiders

Scientists at The University of Manchester and the Manchester Metropolitan University have carried out the first comparative scientific study of ancient spiders trapped in amber more than 30 millions years ago. The study of fossilised spiders from the Baltic (Poland) and the Dominican (Caribbean) regions has revealed new insights into the ecologies of spiders dating back to the Cenozoic pe...

On the track of tiny larvae, a new model elucidates connections in marine ecology

A computer model newly developed by researchers combines ocean current simulations and genetic forecasting to help scientists predict animal dispersion patterns and details of the ecology of coral reefs across the Caribbean Sea. The work is reported by Heather M. Galindo and Stephen R. Palumbi of Stanford University, and Donald B. Olson of the University of Miami, and appears in the August 22nd i...

Different strategies underlie the ecology of microbial invasions

Infectious disease can play a key role in mediating the outcome of competition between rival groups, as seen in the effects of disease-bearing conquistadors in the New World--or, on a much smaller ecological scale, the ability of bacteria to spread their viruses to competing bacteria. In a new study, researchers have compared two different general ways in which bacteria compete with one another,...

Discovery of new cave millipedes casts light on Arizona cave ecology

A new genus of millipede was recently discovered by a Northern Arizona University doctoral student and a Bureau of Land Management researcher. J. Judson Wynne, with the Department of Biological Sciences at NAU and cave research scientist with the U.S. Geological Survey's Southwest Biological Center, and Kyle Voyles, Arizona State Cave Coordinator for the Bureau of Land Management (BLM), c...

Ecology in an era of globalization

In a special issue, Frontiers in Ecology and the Environment explores ecology in an era of globalization, looking at the impacts of human migration, production systems, and invasive species on ecosystems and people throughout North, Central, and South America. Scientists from throughout the Americas gathered last year in Merida Mexico and held a conference on this very topic. The following are h...
