Abstract
Detailed
monitoring of ecosystem metabolism in streams and rivers reveal seasonal and
longitudinal patterns of primary productivity and respiration. The impacts of
riparianzone management and watershed land uses and on in-stream metabolism will
also be discussed. Preliminary studies in tropical streams extend observations
from temperate streams in some intriguing directions. Measurements of primary
productivity and respiration in White Clay Creek, Chester Co., will be
integrated into our understanding of energy flow through the food web in that
stream.
Biography:
Dr. Bott began his biology career as
an undergraduate student at Wheaton College, Wheaton, IL, and then received a
M.S.in Bacteriology and Ph.D. in Bacteriology/Zoology (Limnology) from
University of Wisconsin, Madison. He performed postdoctoral research in
Microbial Ecology in the Department of Microbiology, Indiana University,
Bloomington, IN, before beginning his long-standing interaction with University
of Pennsylvania as an Adjunct Professor in the Biology Department. He was
Curator of Stroud Water Research Center when it was affiliated with the Academy
of Natural Sciences of Philadelphia (1986-1999). In the past ten years his
work at Stroud Water Research Center has yield over seventy publications.
