Phone: 608-781-6231

  • Scientific lead - lower trophic production (nutrients)
  • Research activities include:
    • Evaluating the factors that control aquatic primary production in large floodplain rivers
    • Determining the source and fate of primary production supporting the river food web
    • Evaluating the effects of hydraulic exchange of water (e.g., material transport into and out of floodplain backwaters), suspended particles, and soluites, on algal production and trophic pathways
