Research:
My research interests straddle the interface of freshwater aquatic communities and ecosystems. Research funding is driven by the importance of understanding factors which may compromise surface water quality, aquatic communities, and the inequity of water demand versus supply. Within this focus is an emphasis on how human impacts such as hydrological manipulation, nutrient loading, and fish management affect the structure and function of food webs, and the consequences for ecosystem processes. I am particularly interested in how these perturbations affect food webs and the consequences for energy and nutrient flow through ecosystems.

Current Research Projects:

  • Patterns of [Se] in Kesterson Reservoir Water and Macroinvertebrates (w/ CA Water Institute and U.S. Bureau of Reclamation);
  • Variation in Waterbird Food Production Among Flooded Agricultural Fields (w/ USGS & MS Student Skip Moss);
  • Statistical and Simulation Modeling of Factors Affecting Juvenile Chinese Mitten Crab Mortality and Implications for Predicting Ecological and Economic Harm by Adults (Lead PI-Brian Tsukimura, CSUF & Deborah Rudnick);
  • Factors Affecting Spatial and Temporal Coherence in Algal and Macroinvertebrate Assemblages in the Mae Ping and Mae Kung Rivers (w/ C. Phalaraksh, Y. Peerapornpisal, and T. Kunpradid, Chiang Mai University , Thailand );
  • Relationships Among Food Web Structure and C & N storage and flux through Sierra Nevada Headwater Stream Ecosystems (w/ U.S.D.A. Forest Service & MS Student Nick Basile);
  • Relationships Among Water Quality and Reservoir Storage and Turnover (w/ CA Regional Water Qual. Control Board & MS Student Zak Hoover).
