摘要
The distribution of apogeal mounds of the humus feeding termite Cubitermes sankurensis (Wassmann) was studied in relation to small‐scale variation in vegetation pattern on three permanent transects within a 5 ha stand of miombo woodland. The composition of vegetation did not have a significant effect on the abundance of C. sankurensis. There was an effect of habitat structure on mound distribution with increased aggregation in areas of open canopy. Factors such as colonization potential and the history of termite activity may be more important in determining the distribution of mounds than the heterogeneity of the vegetation. La distribution des termitieres épigées du termite mangeur d'humus Cubitermes sankurensis (Wassmann) a étéétudiée en rélation avec les variations à petite échelle du type de végétation dans 3 transects permanents d'une station de 5 ha dans une forêt de type Miombo. La composition de la végétation n'a pas d'effet significatif sur I'abondance de C. sankurensis. La structure de I'habitat a un effet sur la distribution des termitières, plus abondantes la où la canopée est éclaircir. Des facteurs tels que le potentiel de colonisation et l'historique de l'activité des termites peuvent être plus importants pour dkterminer la distribution des termitières que I'hétérogénéité de la végétation.
