Species richness, community compositions and microhabitat characteristics of non-volant terrestrial small mammals in disturbed habitats in Sabah, Malaysia
A study on the small mammals communities was carried out in disturbed habitats around Sabah, namely Universiti Malaysia Sabah (UMS), bias Peat Swamp Forest Reserve (Klias), Kawang Forest Reserve (Kawang), Kalabakan Forest Reserve (within the SAFE project area) and Maliau Basin Conservation Area (Mal...

The aim of this study was to investigate how the habitat disturbance affects the species richness, community compositions and microhabitat-use patterns of the small mammals. The specific objectives were (1) to determine the species richness and composition of non-volant small mammal communities in disturbed habitats; (2) to characterize the microhabitat use patterns of the non-volant small mammal communities in disturbed habitats; and (3) to determine the microhabitat preferences of the non-volant small mammal communities in disturbed habitats.
