摘要

The endemic sparassid spider Leucorchestris arenicola Lawrence builds silk-lined burrows in low-lying sections of dunes in the Namib Desert. Individuals defend certain areas around the burrow against conspecifics. The hypothesis was examined whether social spacing through territorial behaviour creates regular spacing patterns. A population of L. arenicola was monitored for four months during the reproductive season, when all inhabited burrows inside a 3,300 m2 area were recorded. Spatial patterns were analysed in terms of their degree of randomness or aggregation. The observed patterns between burrows did not fit a regular distribution, but early in the season distribution was random, followed by aggregated distribution at distances greater than 3 m, and later reverting to random again. This aggregation is explained in terms of habitat characteristics and population structure.
