Sanderson, who published an essay with a similarly dire assertion in 2002, concludes these seven years later: “There have been landmark foreign policy acts in the past that managed to satisfy both dom...
Ecology, The Environment and Conservation |New research on bacterial communities throughout six large Arctic river ecosystems reveals predictable temporal patterns, suggesting that scientists could use these communities as markers for monitori...
Life Sciences |These CO2 emissions increased at a rate of 3.4% per year from 2000 to 2008, in contrast to 1% each year in the previous decade, scientists from the Global Carbon Project report in the current issue of...
Earth Sciences |Because most forested areas are in mountainous regions, 40% of U.S. forests are in landslide hazard areas. Thus, the interaction between soil development and mass wasting is critical to understanding ...
Agricultural and Forestry Science |But new research from the University of Washington shows this is not likely to be true. Algae provide a much richer diet for fish and other aquatic life, according to research published this week in t...
Ecology, The Environment and Conservation |Capitalizing on their previous work to decode the genome of the poplar tree, the research team examined how poplar trees use their 45,000 genes to respond to drought. Campbell and PhD student ...
Agricultural and Forestry Science |And when their populations crashed, emptying a land whose diversity of large animals equaled or surpassed Africa's wildlife-rich Serengeti plains then or now, an entirely novel ecosystem emerged ...
Earth Sciences |A suite of five ancient crocs, including one with teeth like boar tusks and another with a snout like a duck's bill, have been discovered in the Sahara by National Geographic Explorer-in-Residenc...
Earth Sciences |The atlas contains the most accurate maps ever assembled for this ecosystem revealing key migratory corridors that span from coastlines to deep-sea feeding areas off the continental shelf hundreds of ...
Ecology, The Environment and Conservation |A team of eleven of the world's top tropical forest scientists, coordinated by the University of Leeds, warn that while cutting clearance of carbon-rich tropical forests will help reduce climate ...
Life Sciences |Marine biologist Fleur Van Duyl from the Royal Netherlands Institute for Sea Research is fascinated by the energy budgets that support coral reefs in this impoverished environment. According t...
Life Sciences |Regulations and guidelines for tolerable concentrations of these potentially plant-toxic elements in soils are based on the assumption that the toxic effects of the metals are substantially independen...
Agricultural and Forestry Science |This suggests that terrestrial ecosystems and the oceans have a much greater capacity to absorb CO2 than had been previously expected. The results run contrary to a significant body of recent ...
Earth Sciences |The kelp forest tripled in size from the peak of glaciation 20,000 years ago to about 7,500 years ago, then shrank by up to 70 percent to present day levels, according to the study by Rick Grosberg, p...
Ecology, The Environment and Conservation |Their findings suggest that the early ocean was much more temperate and that, as a result, life likely diversified and spread across the globe much sooner in Earth's history than has been general...
