While working with pesticides, people accumulate them in the organism, what, in turn, may lead to the chronic diseases. Human needs have increased immensely, and people nowadays can’t eliminate the use of pesticides. (more…)

Students studying what they love is a well-established principle at Brown. For Tyler Coverdale, that meant the outdoors, the environment, and, ultimately, some provocative research on Cape Cod salt marshes through GIS-assisted analysis of historical aerial photography. He loves it.

Tyler Coverdale’s newly published study in Frontiers in Ecology and the Environment on the collapse of salt marsh habitats along Cape Cod tells an intriguing, if unfortunate, tale of how three different human activities spanning 70 years finally added up to a problem that no one anticipated. The story of how he made the discovery — which is generating some buzz in ecology — while a Brown undergraduate is a tale of happier serendipities. (more…)
