Studies on the Small Mammal Fauna of Sabah, East Malaysia II. Karyological Analysis of Some Sabahan Mammals (Primates, Rodentia, Chiroptera)

Abstract

Karyotypes of the following 18 small mammal species from Sabah, East Malaysia, have been analysed. The material includes one tree-shrew (Tupaia montana), 4 rodents (Rattus rattus, Mus musculus, Sundasciurus jentinki, Callosciurus albescence) and 13 bats (Pteropus vampyrus, Cynopterus brachyotis, Aethalops alecto, Emballonura rivalis, Rhinolophus creaghi, Hipposideros diadema, Hipposideros galeritus labuanensis, Tadarida plicata, Myotis horsfieldi, Scotophilus temmincki, Miniopterus schreibersi, Miniopterus magnater, Miniopterus australis). The results were given in Table 2. Karyotypes of 12 species in this paper are described for the first time. All the present data were compared with the respective data hitherto available to the authors, and some discussions were tried on their phylogenetical implications.
