Abstract
Aspects of the home range and space-use patterns of the common wallaroo or euro (Macropus robustus erubescens) were studied over a three year period in arid New South Wales. Thirty-five adults (19 males and 16 females) were captured and fitted with radio-transmitters and their movements followed. The home ranges of the majority of animals were significantly different from that of a bivariate normal distribution, indicating a heterogeneity of space use. Home ranges were small and essentially stable over time. There were significant differences between the sexes in all parameters of home range measured due to differences in ecological and social requirements. Males had significantly larger weekly home ranges in winter than females (77.2 +/- 47.5 ha and 30.5 +/- 16.5 ha, respectively) but in summer home ranges were similar (30.2 +/- 20.4 ha and 27.6 +/- 15.0 ha). On a yearly basis males ranged over an area approximately three times the size of that used by females. Yearly home-range size in males was positively correlated with body size when conditions were poor.
