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…

Scientists are reporting for the first time that the use of weed killers in farmers' fields boosts the nutritional value of an important food a crop. Application of two common herbicides to several varieties of sweet corn significantly increased the amount of key nutrients termed carotenoids in the corn kernels, according to a study scheduled for publication in the July 22 issue of ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication. …
