The Chinese water deer was once widely spread in Liaodong Peninsula, North China Plain and both banks of the Yangtze River and the Korean peninsula. Due to long-term environmental changes and influence of human development, its wild population in China has rapidly declined, both in abundance and distribution. As one of the native species in the history of Shanghai, Chinese water deer was introduced to Shanghai for captive breeding in 2006 and were released into the wild in 2010. The present study was conducted in Nanhui East Shoal Wildlife Sanctuary. The reintroduction of Chinese water deer was carried out separately in June and October 2010. So as to study the movement of the deer after release, 12 Chinese water deer (sex ratio 1 : 1) were tagged with radio-collars. We successfully used radio-telemetry to track 10 deer, and used the minimum convex polygon (MCP) and fixed kernel estimation (FKE) methods to calculate their home range. The results showed that using the MCP method, the mean home-range size of Chinese water deer was estimated to be 671 ha (range 245–1559 ha), while using the 95% FKE method, the mean was estimated to be 262 ha (range 43–435 ha). The mean home-range size of a buck was smaller than that of a doe by both MCP and FKE. The mean home-range size of an adult female was smaller than that of a subadult female. The largest seasonal home-range size (MCP, 275 ha) occurred during the winter of the first year, which then kept on shrinking in spring and summer. Home-range overlap was found among the home range of each individual. The mean overlap size was 303 ha. The mean overlap size was 135 ha in bucks, 422 ha in does and 270 ha between the buck and the doe. The study reflects that the seasonal food change is probably the main factor for the change of home-range size. Oestrus may also result in the enlargement of home range in winter. As an attempt to reintroduce large mammals to cities, we hope to provide useful experience for future wildlife management and conservation.

AbstractHome range and nesting habitat were studied in two sympatric pelomedusid terrapins (Pelusios niger and Pelusios castaneus) from two study areas in the Niger Delta (Nigeria, West Africa), one with pristine habitat conditions and one which was polluted by a oil spill event some years before. Seventy-seven individuals (38 P. niger and 39 P. castaneus) were radiotracked, each for more than 60 days, and their home range was calculated by the minimum convex polygon method, with 95% of the point locations per individual. The mean home range size of females was significantly larger in the polluted area than in the pristine area in both P. niger and P. castaneus, and the mean home range size of female P. niger was significantly larger than that of female P. castaneus in the polluted area, but not in the pristine area. The mean home range size of males was significantly larger in the polluted area than in the pristine area in P. niger but not in P. castaneus, and the mean home range size of male P. niger was significantly larger than that of male P. castaneus in the polluted area but not in the pristine area. Radiotracked females of both species showed a clear preference for nesting sites situated along ponds and not along the banks of the river, on sandy soil, often with abundant vegetation around. Some females of both species deposited their eggs at greater distances from water bodies in the polluted area than in the pristine area. The comparative evidence of these patterns indicates consistent responses of the two species to the altered habitat, which further supports the general hypothesis that habitat pollution has seriously affected the ecological strategies of these terrapin species.

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.

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.

Home range, den density, and use of dens of arctic foxes (Alopex lagopus) in Svalbard were investigated through systematic den surveys, ear tagging of pups, and tracking of radio-collared animals. The mean home range for three breeding vixens was 48 km2. Home-range estimates based on occupied dens were between 46 and 75 km2. This is larger than recorded for arctic foxes elsewhere, and may be related to the absence of small mammals and, consequently, to a more scattered prey base in Svalbard. Home-range size was apparently not related to variations in the availability of food among years or among seasons. The density of all dens recorded was 1/24 km2. As a consequence of landscape patterns, these dens were more clustered than if they were randomly dispersed. However, dens with litters in 1986 (1 den/75 km2) were more widely spaced than if randomly distributed, indicating territoriality among arctic foxes. Most dens were in use throughout the year. Some litters were relocated or subdivided among several dens.

Abstract. Charaspet K, Sukmasuang R, Khoewsree N, Pla-ard M, Songsaen N, Simchareon S. 2019. Movement, home range size and activity pattern of the golden jackal (Canis aureus, Linneaus, 1758) in Huai Kha Khaeng Wildlife Sanctuary, Thailand. Biodiversitas 20: 3430-3438. We studied the movement patterns, monthly home range sizes, and activity patterns of the golden jackal in Huai Kha Khaeng Wildlife Sanctuary (HKK) from November 2017 to June 2019. Data were obtained by trapping and collaring a female jackal with a satellite collar, and from a concurrent camera trap survey. The female jackal had an average daily movement of 1.7 km, and her overall home range size was 26.3 km2, based on 1,191 locations across 7 months and using the 95% Minimum Convex Polygon (MCP) method. The monthly home range size (95% MCP) was the smallest in December (9.2 km2) and the largest in March (20.51 km2). Results from camera traps revealed 33 species of wild animals, including 16 species of carnivorous mammals and 17 non-carnivorous species. The relative abundance index (RAI) of the jackal was 24.33, which was the highest of all carnivore species, and the second-highest of all species, suggesting jackals were one of the most common mammal species in HKK. Based on camera trap data, the mean diel activity of jackals in HKKwas at 00: 46 hours, and their activity overlapped most with potential prey including hares and small rodents. Results also revealed that golden jackals prefer dry dipterocarp forest compared to other habitat types Our results lead to a better understanding of the ecology of golden jackals in Thailand, and provide a baseline for future research on this species.

Abstract:Differences in growth patterns between the sexes of the gracile mouse opossum Gracilinanus microtarsus and the consequences for home range size were investigated in a savanna habitat (cerrado) of south-eastern Brazil. A total of 51 juvenile individuals of Gracilinanus microtarsus was monitored using capture–mark–recapture from November 2005 to August 2006. The increase in body mass of gracile mouse opossums was described using the Gompertz growth model. Male gracile mouse opossums grew faster than females (dimorphic ratio of 1.5). Home range size, estimated with the minimum convex polygon method, was positively related to body mass. Model selection using Akaike's Information Criterion (AICc) and incorporating body mass, sex and season as independent variables showed that the best-supported model describing variance in home range sizes included only body mass. Our data suggest that a greater body mass gain in juvenile males is probably the proximate cause of sexual dimorphism in adult gracile mouse opossums and that energetic needs required for growth have a greater influence in home range size.

Janeiro State

The home range of the Tropidurid lizard Liolaemus lutzae, an endemic species of the costal sand dune habitats of Rio de Janeiro State, was studied in the beach habitat of Barra de Maricá restinga, Maricá County. Home ranges were studied using a mark-recapture technique in a delimited area at the beach habitat. I considered for estimates and analysis the home ranges of those lizards with a minimum of four positions. The size of L. lutzae home ranges varied according to the segment of the population. The mean home range size of adult males (x = 59.8 ± 33.7 m²) was significantly larger than that of adult females (x = 22.3 ± 16.1 m²). Juvenile mean home range size was significantly smaller than that of adult males, but did not differ from that of adult females (t = 1.058; p = 0.149). The overlap between male home ranges was usually low (3.6%), being in general only peripheral. Conversely, there was a considerable overlap between home ranges of adult females with those of adult males, the home range areas of two or three females being enclosed in the home range of one adult male. The small overlap between home ranges of adult males suggested mutual exclusion. The observed between-sex differences in the size of L. lutzae home range may be explained by the sexual dimorphism in body size in this species, and by the need of adult males to establish larger areas so as to include many females in their areas, during the reproductive season. The differences in home range along ontogeny probably result from differences in body size of the different segments of the population, due to trophic differences (carnivory and herbivory levels), and the dispersal of young after birth. Because L. lutzae is omnivorous, but primarily herbivorous when adult, and due to its sit-and-wait foraging behavior (mainly on arthropods), it does not need to move around over large areas to find food, which in turn reduces the area necessary for it to live.

AbstractTigers Panthera tigris are highly threatened and continue to decline across their entire range. Actions to restore and conserve populations need to be based on science but, in South-east Asia, information on ecology and behaviour of tigers is lacking. This study reports the relationship between the home range size of female tigers and prey abundance, using data from radio-collared tigers in Huai Kha Khaeng Wildlife Sanctuary, Thailand, and published data from other studies. A total of 11 tigers, four males and seven females, were fitted with global positioning system collars, to estimate home ranges using 95 and 100% minimum convex polygons (MCP). Prey abundance was estimated by faecal accumulation rates. The mean home range size of male tigers was 267 and 294 km2 based on 95 and 100% MCPs, respectively; the mean female home range size was 70 and 84 km2, respectively. Territories of male and female tigers had little overlap, which indicated both sexes were territorial. Mean densities of the prey species sambar Rusa unicolor, barking deer Muntiacus muntjac and large bovids were 7.5, 3.5 and 3.0 km−2, respectively. When female home range size and prey abundance were compared at six locations in Thailand, and at other sites in India, Nepal, Bangladesh and Russia, a significant negative correlation was found between prey abundance and home range size. Monitoring this relationship can provide managers with metrics for setting conservation goals.
