Research Interests

My primary research focus is on  the structure and dynamics of aquatic food webs, with emphasis on the effects of human impacts and introduced species.  Much of my work is involved with conservation of aquatic organisms and the environments that sustain them.  Studies I am currently involved in include (1) a long-term study of the ecology and conservation of endemic aquatic invertebrates inhabiting thermal springs within the Ash Meadows National Wildlife, with special emphasis on the creeping water bugs (family Naucoridae);  (2) a study of the effects of landscape heterogeneity and wetland succession on spatial distribution, seasonal movements and long-term viability of an Oregon spotted frog (Rana pretiosa) population within the Cascade-Siskiyou National Monument;  and (3) distribution of non-native crayfish their impacts on stream food webs and the native biota.
