Peckarsky, Barbara L.

Professor Emeritus/a

field studies of behavior, life histories and biological interactions among stream-dwelling invertebrates
mechanisms, consequences and evolution of predator-prey and competitive interactions
invertebrates as indicators of stream water quality
systematics of aquatic insects
Consequences of larval interactions to mayfly survival, fecundity and population growth in Rocky Mountain streams:

mortaility of larval mayflies due to predation by stoneflies and trout, mermithid nematode parasites, and competition
sublethal consequences (costs to fecundity and male reproductive success) of predator avoidance, parasitism and competitive interactions
modeling population growth to determine the relative impacts of predation, parasitism and competition on mayfly fitness

effects of avoidance of trout and stonefly predators on mayfly response to algal distribution
effects of mayflies on algal heterogeneity under different predation regimes
modeling patch dynamics to simulate the impact of predator and anti-predator behaviors on prey and resource heterogeneity at multiple scales

simulation modeling to predict effects of variation in recruitment, predation and resources on mayfly abundance
effects of recruitment on mayfly larval abundance
effects of predators and food on mayfly larval abundance
Macroinvertebrates as indicators of impacts on stream habitat quality in upstate New York streams

educating target groups about the theory and practice of biomonitoring streams
assess the impacts of disturbances on local streams
baseline biomonitoring of invertebrates in local streams vulnerable to degradation due to human activities
developing a long term database on local stream invertebrate communities as a basis for understanding the relative importance of natural and human-induced disturbances in explaining population and community flucturations
