Chesapeake Bay has a long history of nutrient pollution resulting in degraded water quality. However, we report improvements in chlorophyll a in surface waters and dissolved oxygen in bottom waters at one of three estuarine stations in the Choptank tributary of Chesapeake Bay. We updated a previous nutrient budget for the estuary constructed for reference year 1998 using rates of atmospheric deposition, inputs of watershed dif...

The natural host behaviours confer protection from infestation by ectoparasitic salmon lice Lepeophtheirus salmonis , yet whether genetic origin results in different behaviours and thus susceptibility to infestation is unknown. In common garden experimen...
