Jason Mark Taylor

Res Ecologist



Dr. Taylor is a Research Ecologist with the Water Quality and Ecology Research Unit located in Oxford, Mississippi. His research has focused on a wide variety of freshwater ecology and management topics including basic life history descriptions, nutrient cycling in freshwater ecosystems, and how stream organisms and communities respond to excess nutrients or altered stream flows. He continues to explore some of these topics within the context of agricultural management by adapting previous work to help develop a better understanding of how freshwater ecosystems behave within agricultural landscapes, and how we can manage aquatic habitats to help mitigate agricultural contaminant loads to downstream ecosystems. For example, since joining ARS Dr. Taylor has focused a portion of his research program on factors influencing processing of both riparian tree and crop residue organic matter in eutrophic agricultural bayous and oxbow lakes, and potential environmental impacts. Dr. Taylor is also working closely with other ARS and university researchers to conduct experiments that identify and quantify mechanisms associated with vegetated agricultural drainage ditches and wetlands that mitigate agricultural runoff contaminants.
