Life cycles reproduction and diets of Dina dubia and Erpobdella punctata (Hirudinea: Erpobdellidae) in Canagagigue Creek, Ontario / D.R. Barton and J.L. Metcalfe.: En13-5/85-65E-PDF
"In recent work on Canagagigue Creek, we found that leeches contained residues of chlorophenols from 10 to lO0X higher other benthic invertebrates and fish. There is evidence from the literature that leeches have a considerable bioaccumulation capacity for other synthetic organic such as DDT and mirex, and even metals. We have therefore suggested that leeches may serve as excellent 'early warning' indicators of contamination, and have recommended their use in biomonitoring. In order to determine pathways for the bioaccumulation of contaminants by these organisms, details of their life histories (e.g. trophic status, longevity) must be known. Unfortunately, the biology of Canadian leech species is poorly known. The present study, believed to be the first of its kind in eastern Canada, provides background information on the reproduction, growth, life cycles and food habits of two species of leeches in an Ontario stream"--Management perspective.
