... a pair of species. It is difficult to find either an ecological or historical explanation for this striking biogeographical feature . All eleven species are widespread in Tasmania and occur on a range of parent geologies, at a range of elevations and in a range of forest and woodland habitats. ...

... factors. At a landscape scale, abundance and taxon richness were influenced by geology (and related aspects of topography and soil), although response patterns varied between groups. There was a marked spatial patterning in richness, probably as a response to a rainfall-related productivity gradient. Past...

... details of vegetation, habitat, substrate and geology were analysed. All species exhibit a broad habitat range, and some are opportunistic exploiter s of novel habitats, such as roadside gravel and under walking track cording. Although patterns of habitat exploitation appear to differ between species...
