South Eastern Australia

Travelling paths and overnight roosts of the lace monitor, Varanus varius, were recorded by radiotracking during periods of up to 19 months in lowland open forest of south-eastern Australia. Home ranges were calculated by four methods: convex polygon (without correction for small sample size), convex polygon (with correction for small sample size), and two 95% probability ellipses. From field observations, I conclude that the convex polygon method without correction for sample size provides the most realistic description of the space used by V. varius. By this method, I calculated a mean (+/- s.d.) home range of 65 +/- 34 ha for 13 male V. varius (mean mass 5.1kg) that were radio-tracked for 2-19 months.

Size Estimates

Home range size estimates in a population of Peromyscus leucopus changed as a function of sample size, reaching an asymptote at nine captures. Despite the short life-span of this species in the wild, a trapping regime that greatly increases the likelihood of obtaining at least nine captures can be devised, although the probability is extremely sensitive to the number of trap nights per session. Home ranges appear not to shift during the time required to obtain sufficient sample sizes.
