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.


Dr. Bott began his biology career as an undergraduate student at Wheaton College, Wheaton, IL, and then received a 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.
