Research & Scholarship
Dr. Voss’s research focuses on understanding the consequences of human-driven land cover change on the integrity of freshwater ecosystems. He uses aquatic macroinvertebrates, small aquatic organisms that spend most of their lives in freshwater ecosystems, as a focal assemblage to answer three main questions: (1) How does land-cover change (e.g., urbanization, agriculture, and surface mining) alter the biodiversity of freshwater systems (streams, ponds, and lakes)? (2) How does biodiversity loss influence ecosystem energetics in aquatic food webs? and (3) How can quantitative tools that freshwater ecosystem managers use to assess freshwater communities be improved? Dr. Voss has current projects examining the effects of urbanization on freshwater pond ecosystems in Denver, the effect of macroinvertebrates on waterbird communities in the San Luis Valley, and sublethal effects of chemical pollutants on dragonflies.
