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…

Extremely hot or rainy periods can destroy entire crops, not to mention the wide variety of pests that can appear on the scene. Bugs such as the vine louse or…
In fact, they flourished. While modern tropical rain forests were becoming established, ferns climbed aboard, and experienced a flowering of their own species…
If the band continues to migrate at just less than a mile (1.4 kilometers) a year, which is the average for all the years it has been moving north, then some…
In the complete absence of stand-replacing disturbances – via fire or timber harvest – forests of Oregon and Northern California could theoretically almost…
“Late blight has never occurred this early and this widespread in the U.S,” said Meg McGrath, associate professor of plant pathology and plant-microbe biology.One of the most visible early symptoms of the disease is brown spots (lesions) on stems. They begin small and firm, then quickly enlarge, with white fungal growth developing under moist conditions that leads to a soft rot collapsing the stem….
This has been a puzzle to climate scientists because leading models have indicated that over the past 24 million years geological conditions should have caused…
El Niño years typically result in fewer hurricanes forming in the Atlantic Ocean. But a new study suggests that the form of El Niño may be changing potentially…
There are of course neither satellite images nor instrumental records of the climate all the way back to the 13th century, but nature has its own 'archive' of…
