James Coles, PhD.

James Coles is an Aquatic Ecologist in the New England Water Science Center.

James has been with the New England Water Science Center since 2007.  His prior academic work focused on identifying environmental factors that contributed to high growth rates of cyanobacteria and its seasonal dominance over diatoms in freshwater systems. More recently he has investigated the effects of watershed development and associated stressors on the condition of stream ecosystems.  Since 2014 he has been the coordinator for the USGS Regional Stream Quality Assessments in New England; these studies include a comprehensive investigation of how stream ecosystems are affected by modified flow regimes, and how watershed development results in multiple stressors that affect water quality and the biotic communities of streams in New England.
