Diversity and biomass of terrestrial small mammals at a Malaysian primary rainforest reserve (Segari Melintang Forest Reserve, Peninsular Malaysia)

摘要: Despite their importance for the rain forest ecosystem, still not much known about community composition of small frugivorous mammals in West-Malaysian forests. Therefore, we conducted a mark and recapture study four 100 m x sized plots lowland Dipterocarp Peninsular Malaysia 4000 trap nights. Plots hosted either or alluvial fresh water swamp vegetation. We assumed that mammal assemblages varied between these two vegetation types. In total 249 different individuals 14 species (9 genera) were caught, comprising rodents treeshrews. The most abundant was common tree shrew ( Tupaia gli s, 25.8 ha -1 ), followed plantain squirrel Callosciurus notatus , 10.25 ) grey rat Lenothrix canus 10.0 ). These three accounted 77.8% biomass per hectare. Sex-ratio treeshrews found at 1:1, whereas Muridae showed male-biased sex-ratios. Shannon-diversity indices (H) all trapping ranged mediocre level. Plot comparison (Bray-Curtis indices) with similar types more structure. Other factors, such as distance to edge joining oil palm plantations seemed influence abundances. Small belong less studied local forests, thus studying ecology is vital order act towards general conservational issues.
