Description Earthworm Ecology In The Riparian Zone

Abstract:
My research established the presence of native and exotic earthworms along forested headwater stream banks in New York State, and focused on four aspects of earthworm ecology in riparian zones: species composition and distributions; community structure of earthworm assemblages; food web interactions; and their influence on nutrient cycling.  Earthworm species abundance at 14 headwater streamside sites in the Catskill State Park and the Helderberg Plateau, were tested for patterns among earthworm species assemblages, including correlations with habitat variables often cited as predictors of earthworm community structure. Habitat variables, primarily associated with soil pH, were correlated with distributions of a few species; but the majority were organized in assemblages with distinct but unexplained regional variation, indicating possible differences in dispersal histories or other unexplained variables.

The Asa Gray Seminar Series is sponsored by the Asa Gray Biological Society, and is the longest running seminar series at Utica College. Scientists are invited from throughout the region to present seminars on their ongoing research. All lectures are held in Donahue Auditorium, Gordon Science Center, at 4:00 p.m. An informal reception immediately follows. Call (315) 792-3028 for more information.
