摘要: Habitat preferences of five species small mammals were studied on a 6.6 ha trapping grid in heathland an undulating, deep, sandy podzol at Cranbourne, Victoria. The 120 sites sorted into groups using polythetic, agglomerative, non-hierarchical clustering procedure with (i) floristic and (ii) structural data. dispersion 4051 trap captures over 28 months was relation to these groupings. Rattus lutreolus showed no preference for any the groups, but good differentiation obtained groups. Dispersion R. related sedge-food index, seasonal change rainfall. rattus areas wet heath high complexity best revealed classification. results other tended favour rather than Pseudomys novaehollandiae Isoodon obesulus preferred dry younger successional stage. Mus musculus generally. This most pronounced spring when population declining. The community (R. lutreolus, rattus) be food specialists habitat generalists P. novaehollandiae, I. obesulus, M. musculus), exhibited converse traits.
