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…
Climatic fluctuations close to the equator show a different pattern to climate change in the Arctic and Antarctic. In the tropics distinct 11500 year…
A classic explanation, proposed nearly 40 years ago, has been that magma is supplied to the volcanoes from upwellings of hot rock, called mantle “plumes,” that…
There, because warm fluid rises and hence induces movement, the turbulent convection can be 100 billion times stronger than in the typical cooking pot. Hot…
Dan Bearden and colleagues note that bleaching already has destroyed up to 30 percent of the world's coral reefs, and scientists are searching for ways to slow…
Changes in the thickness of a glacier are traditionally measured by means of wooden poles and snow-shovels. Those methods are inexpensive and can be carried…
Because excess CO2 dissolves in the ocean—causing it to “acidify” —researchers have been concerned about the ability of certain organisms to maintain the…
Jörg Fröbisch and Kenneth D. Angielczyk of The Field Museum together with Christian A. Sidor from the University of Washington have identified a distant…

The trade is being driven by Asian demand for horns and is made worse by increasingly sophisticated poachers, who now are using veterinary drugs, poison, cross…
The Basque technology centre has updated the traditional system for improving strains of the tuber by involving novel techniques that enable obtaining new…
Over the last few days, satellites have shown forecasters that Nida has zigzagged between 18 and 20 degrees North Latitude on its somewhat erratic northern…
The first comprehensive review of the state of Antarctica's climate and its relationship to the global climate system is published this week (Tuesday 1…
Twentieth-Century global warming of approximately 0.6¢ªC has already affected the Earth's biota and now the major challenge facing ecologists and evolutionary…
Differences are due to regional and local effects. Increased temperatures are having profound effects on key habitats and on power generation the Arabian Gulf.Researcher Dr Thamer Al-Rashidi of the National Oceanography Centre, Southampton, said: “Because the waters of Kuwait Bay are well mixed by the tides, measurements of sea surface temperature can be used to assess temperature trends over time in the bay as a whole.”…
On Monday, November 30, by 4 a.m. ET, Nida had lost her “Super Typhoon” status as a result of wind shear, and is now a typhoon. Nida's maximum sustained winds…
