The largest reservoir in the United States was straining from persistent drought and increasing human demand. Badger Cove, Driftwood Cove, and Grand Wash Bay have receded to become valleys ...


  • The effect of global warming on eutrophication in lakes

    Shallow lakes are an important type of ecosystem that may be vulnerable to current warming trends. A recent study examines just how vulnerable they are. It indicates that climate change combined with nutrient pollution could exacerbate eutrophication and suggests nitrogen levels should be monitored. Shallow lakes are important in their support of biodiversity. However, their large ...
