Dispersal of the alien raccoon dog Nyctereutes procyonoides in Southern Brandenburg, Germany

Sutor, Astrid Siglinde GND

The raccoon dog Nyctereutes procyonoides, an East Asian canid species, was introduced into the European part of the former USSR since 1928. Within 50 years (1935-1984), it colonised a territory of 1.4 million km(2) in Europe. A telemetry study took place in Southern Brandenburg in a 60 km(2) sized study area with a typical mosaic structured East German agricultural landscape. For catching raccoon dogs, 20 trap boxes were set there in an area of 46 km(2), and between February 2001 and July 2004, 15 (5 males, 10 females) adult and 46 (25 males, 21 females) juvenile raccoon dogs were eartagged and adults additionally fitted with radio collars (Biotrack, 150-151 MHz). Data on dispersal behaviour was collected by the relocation points of 11 juveniles (6 males, 5 females). Four juvenile males dispersed even more than 40 km from their trapping places. Additionally, dispersal of two adult males could be documented. This behaviour probably indicates that the German raccoon dog population still is in a process of colonising. This canid's ability for colonising spacious and distant areas during comparative short periods of time and its preference for habitats with richness of water possibly make this species to be an important vector of fox tapeworm Echinococcus multilocularis-a very dangerous zoonosis
