New study finds that the nutritional value of prey within a single species can widely vary, offering key insights for food web dynamics and ecosystem change The hunt is on and a predator finally zeroes in on its prey. The animal consumes the nutritious meal and moves on to forage for its next target. But how much prey does a predator need to consume? Following a period of massive starvation among animals living along the California coast, University of California…
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…
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…
Economically viable production of a perennial grass monoculture from which substantial quantities of biomass are removed annually is expected to require…
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…
The volcano ejected an estimated 800 cubic kilometers of ash into the atmosphere, leaving a crater (now the world's largest volcanic lake) that is 100…
The study recommends protection of the swamp forests adjacent to the southwest border of Lac Télé Community Reserve after recent surveys confirmed that high…
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,…
“We found almost 11 times more events in the first three days after the main event. That’s surprising because this is a well-instrumented place and almost 90…
“It looks unlikely that there will be any substantial near-term departure from recently observed acceleration in carbon dioxide emission rates,” says the new…
ORNL and LANL scientists are exploring the large potential of the earth’s soils to sequester carbon, with estimates claiming that new land-use practices could…
Publishing in the Nov. 19 issue of Science, the researchers, whose senior and first author are at Cornell, have identified the first map of haplotypes – sets…
“The maize genome is a true maze — full of confusing repeats and dead-ends that have troubled would-be sequencers for years,” says Schwartz.Publication of the…
“Tsunamis can neither be prevented nor precisely predicted yet,” says site initiator Dr. Jian Lin, a WHOI geologist actively involved in tsunami research and a…
Using geochemical clues from rocks nearly 3 billion years old, a group of scientists including Andrey Bekker and Doug Rumble from the Carnegie Institution have…
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,…
The findings, reported this week by scientists from the British Antarctic Survey (BAS), the Open University and University of Bristol in the journal Nature…
