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…
One of the most bizarre-looking fossils ever found – a worm-like creature with legs, spikes and a head difficult to distinguish from its tail – has found its…
Local surface uplift can block rivers, particularly in mountainous regions. The impounded water, however, always finds its way downstream, often cutting a…
In a paper published in Science, the researchers report that about one quarter of the global glacier mass loss during the period of 1851 to 2010 is…
Julio is far enough away from Hawaii so that there are no coastal watches or warnings in effect.
Both factors — resource allocation and hydraulic limitation — might play a role, and a scientific debate has arisen as to which factor (or what combination)…
Turtles are well known for their longevity and protective shells, but it turns out these reptiles use sound to stick together and care for young, according to…
Genomic prediction, a new field of quantitative genetics, is a statistical approach to predicting the value of an economically important trait in a plant, such…
For the first time, an international team of scientists provide a comprehensive estimate on the full range of Antarctica’s potential contribution to global sea…
Iselle was once a rather powerful category 4 hurricane in the East Pacific with sustained winds estimated at 120 knots (~138 mph) by the National Hurricane…
NASA's Terra satellite passed over Julio and saw that the bulk of the clouds and precipitation were being pushed to the34 north of the center as the storm…
“Eastern hemlock trees have died throughout much of their range due to the hemlock woolly adelgid, an exotic invasive insect,” said Steven Brantley, a…
Now that people are more concerned than ever about what is happening at the poles, a new study confirms that snow has thinned significantly in the Arctic,…
The team compared mainstream bioeconomic theory — which policymakers have depended on in order to protect fish populations — with the lesser-known…
Man-made global warming can explain a gradual increase in periods of severe heat, but the observed change in the magnitude and duration of some events is not…
“We have been building models and there are now robust contradictions,” says Liu, a professor in the UW-Madison Center for Climatic Research. “Data from…
