[Trends of faunistic-ecological researches in the Department of Parasitology in Wrocław University].

Paper deals with the results of systematic-ecological investigations of host-parasite relationships in the context of 45 year history of the Parasitological Department at the University of Wrocław. Achievements are concentrated on the presentations of new taxonomic units and rearrangement of classification of parasitic protozoans and tapeworms (J. Janiszewska), nematodes (A. Okulewicz), lice (J. Złotorzycka, E. Lonc, M. Modrzejewska). Faunistic and biometrical data of parasitic commities of fishes, birds and mammals, mainly rodents as well as the vector role of ticks and mosquitoes at Wroclaw area are also discussed. Localities of those parasites and their hosts, collected mainly from the Lower Silesia region are rearranged according to new system of physicogeographic differentiation of Poland and its regional position at biogeographical map of world.
