调查了甲壳虫群落格局与海拔高度(700、1700、2700和3100 ma.s.l)的关系。和地质基底(即非超基性岩和超基性岩)。马来西亚沙巴州基纳巴卢。在同一海拔高度上，非超基性样地的甲螨密度和形态种类丰富度均大于超基性样地。甲螨在两种基质上的密度和丰富度都随着海拔的升高而降低，但海拔对非超基性基质甲螨密度的影响没有超基性基质显著。甲螨密度与土壤有机磷含量呈正相关，与土壤交换性钙含量呈负相关。甲螨形态种丰富度与凋落物中磷含量、地上生物量、乔木多样性和凋落量呈正相关，与海拔和土壤钙含量呈负相关。在每个样地中，形态种均为耳科、耳科、单倍体科和角鲨科的优势种。典型对应分析(CCA)表明海拔高度对甲螨群落结构的重要性。综上所述，甲虫群落的总密度或形态种丰富度受地质条件和海拔高度的共同影响，形态种组成受海拔高度的影响较大。(C)2006年爱思唯尔·马森公司。版权所有。
The patterns of oribatid communities were investigated in relation to elevations (700, 1700, 2700 and 3100 m a.s.l.) and geological substrates (i.e. non-ultrabasic and ultrabasic rocks) on the slopes of Mt. Kinabalu, Sabah, Malaysia. The density and morphospecies richness of oribatid mites were greater in the non-ultrabasic plot than in the ultrabasic plot at each of the same elevations. The density and richness of Oribatid mites decreased with elevation on both substrates, but the effects of elevation on the density on non-ultrabasic were less significant than on the ultrabasic substrate. Oribatid mite density correlated positively with the concentration of soil organic phosphorus and negatively with that of exchangeable Ca in soil. The richness of morphospecies of oribatid mites positively correlated With phosphorus concentration in litter, above-ground biomass, tree diversity and litterfall amount, and negatively correlated with elevation and Ca in soil. Morphospecies from families Galumnidae, Otocepheidae, Haplozetidae and Scheloribatidae were dominant in each plot. Canonical correspondence analysis (CCA) showed the importance of elevation for the community structure of oribatid mite. In conclusion, total density or morphospecies richness of oribatid communities was influenced by both geology and elevation, and morphospecies composition was strongly influenced by elevation.
