摘要

Terrestrial small mammal community composition was examined in the Volcanoes National Park (VNP), Rwan- da with respect to variation in habitat type and altitude. Trapping resulted in the capture of 220 individuals including eight species of rodents, three species of shrews and one mongoose. Of the species captured, Praomys degraaffi is vul- nerable and Sylvisorex vulcanorum is near threatened (IUCN 2012). Six species (Hylomyscus vulcanorum, Mus bufo, Praomys degraaffi, Sylvisorex vulcanorum, Lophuromys woosnami and Tachyoryctes ruandae) are endemic to the Alber- tine Rift. Species richness and diversity varied significantly among the different habitat types as they increased with el- evation up to the middle altitudes (2860–3255m) and then declined with increasing elevation. Altitude accounted for 20 % of the variation in species diversity. Species variation in habitats and altitude was related to environmental factors. Endemic species were found mainly in low and middle attitude habitats; thus these habitat types are important for con- servation of small mammals at Volcanoes National Park.
