摘要

The ant communities of the soil litter layer were studied along an elevational gradient on Mount Kinabalu, Sabah, in primary rain forest systems ranging from dipterocarp hill forest to dwarf forest at altitudes of 560, 800, 1130, 1360, 1530, 1740, 1930, 2025, 2300 or 2600 m above sea level. The ant fauna along the gradient included 283 species of 55 genera. The number of ant species in the leaf litter decreased exponentially without evidence of a peak in species richness at mid-elevations, which was in contrast to many findings on altitudinal gradients for ants and other animal groups. Most ant species have a very limited altitudinal range leading to high turnover values when comparing communities of different altitudes. Of the ant species, 74% were even restricted to one site. It is suggested that the altitudinal ranges of species may be very narrow and that elevational gradients are therefore extremely species-rich and might serve as a prime example of hot spots of biodiversity.
