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…
Their findings, published in the open-access, peer-reviewed journal PLOS ONE, conclude that biofuel crops proposed for use in the Hawaiian Islands are two to…
Rivers in some of the world's most populous regions are losing water, according to a comprehensive study of global stream flows. The research, led by…
Reporting in the journal Geophysical Research Letters scientists from British Antarctic Survey (BAS) and NASA say that while there has been a dramatic loss of…
The study, led by scientists at the National Center for Atmospheric Research (NCAR), suggests that in many cases the reduced flows are associated with climate…
With the increased awareness on the need to clean-up its rivers, Bulacan’s local government units have tapped UP Los Baños-BIOTECH to help in setting up…
The increase in warmer and drier climates predicted to occur under climate change scenarios has led many scientists to also predict a global increase in the…
Their rise and fall are caused by slight changes in the Earth's orbit around the Sun due to the influence of the other planets. But we do not know the exact…
Scientists at Harvard University have found that tropical cyclones readily inject ice far into the stratosphere, possibly feeding global warming.The finding,…
The McMurdo Dry Valleys of Antarctica are devoid of animals and complex plants and scientists consider them to be one of the Earth's most extreme deserts. The…
By sampling clouds — and making their own — researchers have shown for the first time a direct relation between lead in the sky and the formation of ice…
The Colorado River system supplies water to tens of millions of people and millions of acres of farmland, and has never experienced a delivery shortage.But if…
Up to now, a simultaneous consideration of both influences and their interaction is still lacking. With the new European cooperative project AMBER (Assessment…
Even if all three barriers are damaged, the nuclear fuel will not dissolve into the groundwater, according to a new doctoral dissertation from Chalmers…
Concentrations of carbon dioxide are increasing rapidly in the Earth's atmosphere, primarily because of human activities. About one third of the carbon dioxide…
Described in the April 17 issue of Science, the ecosystem lives without light or oxygen in a pool of brine trapped below Taylor Glacier and next to frozen Lake…
