Abstract
Data from a general survey of the soil and litter arthropods of Aldabra have been analysed in an attempt to reveal patterns in the distribution of the species. Analysis by means of a similarity index suggests that their distribution within 14 sites that were sampled quantitatively is to a large extent independent of vegetation type. This is supported by the results of a correspondence analysis of the faunal content of a total of 70 sites representing a variety of vegetation types from several localities around the atoll. It is suggested that this apparent lack of any clear association between vegetation type and fauna may be due to niche expansion by the immigrant species.
