Small Mammals (Mammalia: Rodentia et Insectivora) from the Upper Tisa River Basin (Romania)

摘要: During two field campaigns in August 2009 and May-June 2011 a series of investigations using live trapping was carried out in 5 stations along the rivers Vişeu and Iza, in the Tisa River Basin. The researches aimed to draw up a chorological list for the small mammal species and to characterize the community’s structure and a similitude analysis of the research stations from this area. Up to the present 28 species are known from Upper Tisa River Basin, among them 8 insectivores and 20 rodents, one rodent (Rattus rattus) being probably extinct from the area.
