Very few multi-species or ecosystem comparisons of post-fire vertebrate herbivore activity and food preference exist to inform fire management conservation strategies. We inferred (1–3 years) native introduced attraction six diverse temperate vegetation communities (grassland rainforest) from scat counts. hypothesised that where reduced herbaceous grassy (‘fodder’), herbivores would decline, pr...
Coccidial oocysts morphologically consistent with Eimeria ursini Supperer 1957, and E. tasmaniae Supperer 1957 were recovered from the feces of wild and captive hairy-nosed wombats (Lasiorhinus latifrons) in Australia. Eimeria arundeli so. n. was recovered from the feces of wild and captive common wombats (Vombatus ursinus). Eimeria arundeli oocysts are ellipsoidal to slightly ovoid 60.2--67.2 ...

An oestrous cycle length of 33 days (N = 4, range 32-34) was obtained for the common womab from a number of parameters including vaginal smears, vaginal biopsies, changes in pouch morphology and behavioral observation. All but one of the successive periods of oestrus occurred during winter. Hourly measurements of body temperature by telemetry showed a rhythm typical of nocturnal species. Superi...
