摘要: Communities of metazoan parasites in ten species fishes from Cold Lake, Alberta are described and compared. Relative abundances the overall community lake were estimated using data on abundance each host species, plus estimates relative hosts. Parasites numerically dominant salmonid dominated community, with over half individual being Metechinorhynchus salmonis. Exchange between was greatest related and/or abundant species. Parasite communities cisco whitefish, Coregonus spp., relatively rich diverse (Simpson's index) compared those other lakes North America; trout, Salvelinus non-salmonid poor low diversity lakes. overlaps (Jaccard Lake greater than within The same pattern is seen some These features support hypothesis Wisiewski (1958); that parasite an ecosystem characterized by
