Dense stands of Arundinaria gigantea (Walt.) Chapm. or canebrakes werecommon in the southeastern US, but currently are a critically endangered ecosystem with less than 2% of their area remaining. Remnant canebrakes have become fragmented and isolated.In this study, arthropod communities within these canebrake patches and non-cane patches were examined to assess general island biogeography theories.Four patches (>0.5ha; <0.5ha to >0.1ha; <0.1ha; adjacent non cane patch) were selected at four sites in the Mississippi alluvial valley during three collection periods. Measures of diversity, community composition, and functional group organization were compared to determine if differences existed.Diversity measures and functional group organization did not differ among patch sizes. Diversity measures decreased as distance from canebrakes increased. Canebrakes contained many species that were not found in adjacent non-cane patches with almost 97% uncommon to rare. Conservation of canebrakes is necessary to maintain the biodiversity of these uncommon arthropods.
