In the latest issue of 'Current Biology', researchers from the British Antarctic Survey (BAS) have published an analysis of growth rates of a tiny sea animal. Samples of the bryozoan, (Cellarinella nutti) a sea-bed filter-feeding animal that looks like branching twigs, collected during Captain Scott's Antarctic trips, are yielding data that may prove valuable in projecting climate change, BBC News is reporting. The samples were collected in the Ross Sea, where Capt. Robert Falcon Scott...

Led by scientists at Woods Hole Research Center A new study released today in the EarlyView of Ecology Letters addresses forest productivity trends in Alaska, highlighting a shift in biomes caused by a warming climate. The findings, conducted by scientists at the Woods Hole Research Center and three other institutions based in Alaska and France, linked satellite observations with an extensive and unique tree-ring data set. Patterns observed support current hypotheses regarding increased...

A coupled-cycles framework is essential to balancing human needs with the health of the planet If society wants to address big picture environmental problems, like global climate change, acid rain, and coastal dead zones, we need to pay closer attention to the Earth's coupled biogeochemical cycles. So reports a special issue of Frontiers in Ecology and the Environment, published this month by the Ecological Society of America. "There are nearly seven billion people on the planet. And our...

Frontiers in Ecology and the Environment issue examines the basic elements of life In the search for life on Mars or any planet, there is much more than the presence of carbon and oxygen to consider. Using Earth's biogeochemical cycles as a reference point, elements like nitrogen, iron and sulfur are just as important for supporting life. As explored in studies published in February's open-access Special Issue of Frontiers in Ecology and the Environment, the most basic elements work together...

DNA evidence supports a coastal northeastern Atlantic glacial refugium for a boreal tree species Can a road-trip across eastern North America, ancient ice sheets, and DNA samples unlock the ancestral history of jack pine trees? Julie Godbout and colleagues from the Universit© Laval, Quebec, Canada, certainly hoped that driving across northeastern U.S. and Canada to collect samples from jack pine trees would shed some light on how glaciers may have impacted present-day pine genetics....

Study finds that the areas are most important for a limited range of land cover types Protected areas are generally seen as a triumph for the preservation of nature, yet the reality on the ground is more complex. The world's largest protected areas encompass vast amounts of wilderness but do not extensively overlap the highest priority areas for conservation or include unusually large numbers of birds, amphibians, or mammals, according to an analysis published in the November issue of...
