Biodiversity and biogeographic relationships of selected invertebrates from urban bushland remnants, Perth, Western Australia

Abstract

The results of a continuous pitfall trapping programme designed to collect ground-dwelling invertebrates on the Swan Coastal Plain, Perth, is documented. Of the groups identified to date (Arachnida, except Acarina and some Araneae, scolopendrid and scutigerid centipedes, cockroaches and baeine wasps), 181 species have been identified, indicating a rich assemblage. Average linkage clustering analysis (UPGMA) of similarity indices derived from species abundance data is presented for some groups, which show differing patterns in relation to vegetation and landform. Larger bushland remnants have higher species richness and abundance
