Richard E Lizotte






Education and Research Experience:


Dr. Richard Lizotte's career with USDA-ARS began in 1998, as a Category III biologist with the Water Quality and Ecology Research Unit, at the National Sedimentation Laboratory in Oxford, MS. He became a permanent Category I research ecologist in 2008 within the same unit. Dr. Lizotte received his Ph.D. degree in 1998 in biological sciences from the University of Mississippi with an emphasis on aquatic toxicology/ecotoxicology. His M.S. degree was received in 1994 in biology from the University of Memphis with an emphasis on vertebrate zoology and his is B.S. degree was received in 1990 in biology from Fitchburg State University with an emphasis on environmental science.


Research Interests:


Career research has focused broadly on water quality and ecological aspects of aquatic ecosystems. Early research assessed water quality improvements within the Mississippi Demonstration Erosion Control project (DEC) and the Mississippi Delta Management System Evaluation Areas project (MD-MSEA)Concurrently with MD-MSEA, research was conducted on the effects of pesticide loads in lake sediments and water on aquatic invertebrates. With the initiation in 2003 of the national Conservation Effects Assessment program (CEAP), research interests branched out into evaluating a variety of wetland systems as agricultural conservation practices for water quality and habitat improvement. More recent research has focused on the assessment of agricultural best management practices (BMPs) at broader long-term watershed-scales on improvement of water quality and ecological resources. Currently, his research includes contributions to the Long-term Agroecosystem Research Network (LTAR) of agricultural watersheds and landscapes within the lower Mississippi River basin. Dr. Lizotte utilizes a variety of research techniques at various scales from laboratory, mesocosm, to large-scale field studies to elucidate how BMPs can protect and enhance aquatic resources.


Research Objectives:


••         Assess farm and land management practices (such as BMPs) that improve water quality  

       and protect ecological resources.


••         Examine the structure, function, and important processes of aquatic ecosystems in

       agricultural watersheds.


••         Conduct integrated assessments of the effects of agricultural practices on ecosystem

       services at the watershed scale.
