Includes bibliographical references. "As part of the Canadian Wildlife Service (CWS) Long Range Transport of Air Pollutants (LRTAP) Biomonitoring Program, littoral zones of 62 small lakes and wetlands in the Algoma, Muskoka and Sudbury regions of Ontario are sampled on a regular basis for various prey of resident waterfowl. These prey include macroinvertebrates, fish and amphibians, many of which are acid-sensitive and absent from lakes degraded by acid precipitation. This Food Chain Monitoring Program (FCMP) will detect changes in the composition and abundance of major prey as damaged aquatic ecosystems recover from the effects of acid precipitation as a result of emission abatement programs. This report contains information on the locations, methods and timing of these collections. More importantly, this report summarizes the invertebrate, fish and amphibian taxa collected between 1987 and 1994, along with the locations of the collections, the taxonomic keys used for identifications and the minimum pHs at which the specimens have been caught. This information is intended as a reference for other researchers working on these same taxa or types of lakes, but we caution that the effectiveness of our sampling procedures varies among taxa, and thus minimum pHs of collection may not represent the true thresholds for some species"--Abstract, p. iii.
