Over much of Tasmania, the biogeographic distribution of calanoid copepods is a natural one, achieved before or after the last glacial epoch. However, the construction of several hydro-electricity schemes, with diversion of waters from one catchment to another and the creation of standing bodies of water, often where none previously existed, has transferred some species to localities far from their natural ones. The observed pattern of distribution of centropagid copepods in central Tasmania is related to anthropogenic interferences where the main factor is hydraulic manipulation of catchments for hydro-electric generation.
