Over Time

Home ranges of sympatric red kangaroos, Macropus rufus, and western grey kangaroos, M. fuliginosus, were determined by radiotracking 48 individuals over 20 months. More than 90% of individuals of each species remained within home ranges of less than 10 km2 (mean � SE, 7.74 � 0.90, reds; 6.92 � 0.77, western greys). At no time did any individual disperse far, the longest movement being 13 km. Based on diurnal locations (resting sites) only, home ranges of red kangaroos were larger than those of western greys (P<O.001), and those of kangaroos on Kinchega National Park smaller than those on the adjacent pastoral leasehold (P<O.05). Home ranges calculated from nocturnal and diurnal locations (feeding sites and resting sites) were no different in size for either species, sex or location, but reds, males, and kangaroos on Tandou sometimes moved further between nights and between seasons than did western greys, females, and kangaroos on Kinchega, respectively. Size of quarterly home ranges of red kangaroos changed over time, being positively correlated with minimum temperature (r=0.96; P<O.O5), solar radiation (r=0.99; P<0.05) and evaporation (r=0.99; P<O.O5). Home-range size for western greys did not change significantly over the duration of the study.

The movements of a subalpine population of feral pigs were examined at Kosciusko National Park in southeastern New South Wales. Sufficient data were collected to estimate the home-range area of 20 pigs on the basis of 782 telemetry and trap locations. Mean (+/- s.d.) home-range size (minimum convex polygon method) for males (35.0 t 22.2 km*2) was significantly greater than that for females (1 1.1 +/- 5.2 km*2). Use of capture-recapture distances to estimate home-range size was considered inappropriate. A test for nomadism suggests that, although home ranges of pigs in this environment were larger than those reported for other pigs in Australia, the pigs were essentially sedentary. Management implications for this population are discussed.

Range Estimate

The home-range area of animals may vary geographically and in response to habitat quality. We investigated the size of squirrel glider (Petaurus norfolcensis) home ranges near Brisbane, Queensland, and at Tea Gardens on the central coast of New South Wales. Habitat at both sites had been partially cleared and had been subjected to grazing for several decades. Twelve gliders were tracked over an average of 3.5 months in Brisbane. The fixed kernel (FK95%) home-range estimate averaged 4.6 ± 0.7 (s.e.) ha while the minimum convex polygon (MCP100%) averaged 6.7 ± 1.5 ha. Six gliders were tracked over 1 month at Tea Gardens. The FK95% home-range estimate averaged 14.8 ± 2.4 ha while the MCP100% averaged 13.3 ± 3.1 ha. The Tea Gardens values are derived from relatively short periods and are likely to underestimate the areas used. This study demonstrates that home-range size can vary substantially in the squirrel glider. This has implications for understanding how this species responds to variation in habitat quality and highlights the need for site-specific studies to inform aspects of management.

Lactating Females

The kangaroo populations of Kinchega National Park respond differently to shifts in pasture productivity, red kangaroos Macropus rufus being mobile and unevenly distributed with respect to soil and vegetation types, by comparison with the more evenly dispersed western grey kangaroos M. fuliginosus and the sedentary and localized euros M, robustus erubescens. Red kangaroo population classes tend to be differentially distributed, so that large males and heavily lactating females predominate on the seasonally preferred pastures, while other classes tend to predominate elsewhere. This finding has several implications for the management of red kangaroos and for our understanding of their resource ecology and mating systems.

Macropus Rufus

Between July 1979 and November 1980 a total of 261 red kangaroos, Macropus rufus, (216F; 45 M) and 170 western grey kangaroos, M. fuliginosus, (136F;34M) were caught and tagged with individually recognisable collars. Between July 1979 and January 1986, 1751 sightings of tagged individuals were recorded. Information gained from these sightings was used to assess how far each kangaroo ranged. More than 90% of individuals of either species did not range far (<9 km for reds; <6 km for western greys) even when local pastures were severely depleted during drought. A few individuals dispersed much further-up to 323 km. On average, red kangaroos ranged further than western greys. Kangaroos on Kinchega National Park ranged no less or no further than those on an adjacent pastoral leasehold. At least 17 tagged individuals crossed the macropod-deterrent fence surrounding Kinchega; several crossed repeatedly. Dispersal of kangaroos from Kinchega was slight, supporting the hypothesis of Bayliss (1985) that dispersal has no significant impact on population dynamics.

Adult Cats

Twenty-one feral cats were radio-tracked using direct sighting and triangulation techniques (amassing 730 location fixes) during winter in an agricultural landscape in central-western New South Wales. Factors affecting home-range size, home-range overlap and habitat use were assessed. Mean home-range size was 248 ha (s.e. = 34.9, n = 15 cats, 598 location fixes). Home-range size and habitat use were not influenced by sex or age of adult cats, prey abundance or time of day. However, cat weight significantly influenced range size, with heavier cats having larger ranges than smaller cats. Although the cats are apparently solitary, their home ranges overlapped considerably, particularly between young adults and old adult cats. Cats were active both by day and night and did not occupy permanent dens. Home ranges encompassed mixed habitat types that provided both shelter and prey. Open woodland and open forest were the main habitat types covered by home ranges, but within these areas cats showed a preference for grassland, where rabbits were more abundant. The results recorded in this study indicate that cat-control programs should concentrate in mixed habitat areas, where both shelter and food are available, and over widely dispersed areas. The absence of group living suggests that the effectiveness of virally vectored fertility or biological control agents would be limited.

The Mean

In this study 10 free-roaming domestic dogs from an Aboriginal community were radio-collared to determine the sizes of their home ranges and to observe their wandering behaviour. Half of the radio-tagged dogs went on wandering forays, while the other five roamed only within the vicinity of the community. Home-range size was highly variable within the study group: the mean for the wandering dogs was 927 ha whereas that of the sedentary dogs was 2.6 ha. Dogs travelled 8–30 km on forays. All forays were initiated at night and those that were recorded had an average duration of 26 h. Foray destinations were usually riparian habitats where macropod quarry were abundant.

The factors that affect the trappability of the red fox (Vulpes vulpes L.) in alpine and subalpine New South Wales were examined by means of treadle snares. Trapping (1) on animal tracks without the use of a bait or lure, and (2) by setting snares around a bait, led to the capture of individuals of both sexes and all age-classes. A greater number of foxes was captured per number of snares set in winter than in other seasons because of the commensal foraging patterns of foxes at this time. Foxes were more likely to be caught within 100 m of their home-range boundaries during snow-free months and outside their home ranges while foraging at ski resorts in winter. Snares were found to be difficult to set, and foxes were captured in only 50% of sprung snares. Treadle snares caused no apparent long-term injuries to 40 red foxes that were radio- tracked and observed for 1–24 months after capture.

The Common

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.

The hypothesis that disturbance from a shooting exercise using a helicopter will influence the behaviour of surviving feral pigs, Sus scrofa, was tested on a population of radio-collared feral pigs in north-western New South Wales. No significant differences existed in hourly distance moved by pigs, diel variation in distance moved by pigs, or home-range size of pigs, between a radio-tracking session conducted immediately before a shooting exercise from a helicopter and a radio-tracking session conducted during and after the exercise. The position of the home ranges of feral pigs did not appear to be affected by the shooting exercise, although several radio-collared feral pigs moved into and out of the study area between tracking sessions. Overall, the results suggest that the disturbance caused by shooting has little effect on the behaviour of surviving feral pigs.

A total of 115 Macropus rufus was collected at bimonthly intervals at Menindee, New South Wales, Australia, in 1976 and 1977 and examined for parasites and pathological changes. The animals came from 2 populations, one free-ranging and the other a high-density, enclosed population in Kinchega National Park. No differences in species of helminths present, in prevalence or intensity of infection were noted between the 2 populations. The stomachs were infected with Labiostrongylus longispicularis (prevalence 87.8%), Rugopharynx australis (98.2%), Zoniolaimus spp. (81.6%), Cloacina spp. (71.1%), Papillostrongylus labiatus (47.4%) and Filarinema spp. (92.2%). Hypodontus macropi (93.0%) was the dominant species among the 2 species of cestodes and 3 of nematodes found in the intestine. Progamotaenia festiva (in 74.3%) was found in the bile ducts where it caused mild cholangitis. Only 2 nematode species, F. flagrifer and H. macropi, caused gross and histological lesions. Apart from L. longispicularis none of the helminths showed seasonal variations in prevalence or numbers. Data on worm numbers in relation to host age and on site distribution in the host are presented. The various haematological parameters measured showed no evidence of adverse effects by the parasites, and corticosteroid levels were judged to be within the normal range. The helminth faunas of 9 M. fuliginosus and one M. robustus, grazing sympatrically with M. rufus inside the park are listed. ADDITIONAL ABSTRACT: The parasites reported from 115 red kangaroos (Macropus rufus) in New South Wales in 1976-77 include Tracheomyia macropi (Frogg.), which infected the trachea in 54.5% of the kangaroos [see RAE/B 4, p. 122].
