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.

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.

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 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.

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.

Individuals from a population of Hastings River mouse (Pseudomys oralis) were radio tracked in a short-term investigation of home range, habitat use and movement patterns in Marengo State Forest on the northern tablelands of New South Wales. Results were assessed in the context of conservation and management of this threatened species and compared to research in other parts of the species? distribution. The mean summer-autumn home range (Minimum Convex Polygon) of five animals that met the home range asymptote was 0.78�ha, the minimum home range for fourteen mice was 0.72�ha, while median home range for males was 0.8�ha and females 0.53�ha. There was no significant difference in home range size between sexes. Habitat data indicated that fallen logs, including tree head and butt residue following logging, are important refuge and nest sites, even when rocks and hollows are available. A diversity of fern and other ground plant species (including grasses) was important habitat for the species, microhabitat consisting predominantly of sedge and rush was not favoured.

The effects of short-term disturbances that result in changes to movement patterns and/or behaviour of wildlife are poorly understood. In this study the movements of seven koalas were monitored before, during and after a five-day music festival. During the monitoring program koalas occupied home-range areas of 0.6–13 ha with one or more core areas of activity. Aversive behaviour in the form of evacuation of known ranging areas was demonstrated by three koalas that had core areas within 525 m of the approximate centre of the festival area, the associated responses comprising movements that were perpendicular to and away from staging areas where music was played. Responses contained within known ranging areas were observed in three other koalas whose core areas were located up to 600 m away. The type of response appeared related to the proximity of koala home ranges to music-staging areas, while the maximum distance associated with an aversive response was 725 m. Six of the radio-tracked koalas returned to their home-range areas following the conclusion of festival activities. While the specific stimulus eliciting aversive behaviour was not identified, responses in all instances were initiated during the musical phase of the festival event. The potential for short-term disturbances such as music festivals to significantly influence the ranging patterns of koalas warrants recognition of possible longer-term ecological consequences for planning and management purposes.

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.

Tengmalm's Owl

Abstract Animal home ranges are typically characterized by their size, shape and a given time interval and can be affected by many different biotic and abiotic factors. Understanding of animal movements and assessing the size of their home ranges are essential topics in ecology and necessary for effective species protection, especially concerning birds of prey. Using radio-telemetry (VHF; 2.1 g tail-mounted tags) we studied the movements of two Tengmalm’s owl (Aegolius funereus) males during the breeding season 2008 in a mountain area of Central Europe (the Czech Republic, the Jizera Mountains: 50˚ 50’ N, 15˚ 16’ E). We determined their average nocturnal hunting and diurnal roosting home range sizes. The mean hunting home range size calculated according to the 90% fixed kernel density estimator was 251.1 ± 43.2 ha (± SD). The mean roosting home range size calculated according to the 100% minimum convex polygon method was 57.9 ± 15.8 ha (± SD). The sizes of hunting home ranges during breeding in this study coincide with those previously reported by other studies focusing on Tengmalm’s owl males. However, we found the roosting home ranges were smaller in size compared to those previously reported. This result was most probably connected with different habitat structure in our study area, which was severally damaged by air-pollution in the past, thus probably offering fewer suitable hiding-places, for instance from predators. We found the roosting locations were concentrated in the oldest and densest Norway spruce forest patches. We emphasize that these parts of forest stands require the highest possible protection in our study area.
