“…In agreement with studies in Northern Europe (Kauhala et al 2005;Dahl and Willebrand 2005), we found significant differences in autumn home range compared to home range size in the other seasons. In autumn, hares have just finished a period of high energy expenditure due to breeding activity, and in other populations, the end of the breeding season is the period of the year when hares have the lowest body mass (Van der Merwe and Racey 1991).…”

“…In contrast, hares in boreal forest used different areas in different seasons in relation to distribution of resources (Dahl 2005b). This long-term (year to year) site fidelity agrees with the hypothesis proposed by Dahl and Willebrand (2005) that the knowledge of an intensively frequented area is an important element of habitat quality.…”

Space use patterns of mountain hare (Lepus timidus) on the Alps

et al. 2010

Populations on the limits of species' distribution can show different behavioral adaptations to strong ecological pressure than in the central part of the range. We investigated space use patterns of alpine mountain hare (Lepus timidus) at two areas on the southern edge of the species' range. We monitored 34 hares between 2005 and 2008, estimating home range size, overlap, and site fidelity, and compared our results with space use in Scottish and North-European populations. Home ranges of mountain hares did not differ between two study areas with different habitat types. Subadult animals used larger ranges than adults and both age groups reduced home range size in autumn, a period that might be critical for hares due to changes in diet and/or high energy expenditure during the previous breeding season. Home ranges in these alpine populations were smaller than in Scandinavian populations but within the range of populations in different habitat types in Scotland. Seasonal home ranges overlapped considerably, but differed among the sexes: male-female overlap was higher than same sex (male-male and female-female) spatial overlap. Seasonal shifts of home ranges were small, and site fidelity remained high over the seasons, suggesting that resource distribution remained constant throughout the year and that the knowledge of an intensively frequented area is an important element of habitat quality. We concluded that habitat structure and availability of mates interact in affecting mountain hare space use in alpine habitats.

“…We were unable to find an asymptote in a number of telemetry locations, even when only adult resident individuals with ≥30 locations were used (n=15; 100 simulations). Therefore, we based sample size requirements for home range on a regression analysis to find a cut-off point where there was no positive correlation between home range size and number of locations (Dahl and Willebrand 2005).…”

Space use and territoriality of wolverines (Gulo gulo) in northern Scandinavia

2009

Space use and territoriality influence population structure and dynamics and is therefore an important aspect in understanding the ecology of animals. We investigated spatial and temporal space use of wolverines (Gulo gulo) in northern Scandinavia. We estimated home ranges of 24 radio-marked individuals (17 females and seven males). Male home ranges (mean 669 km 2 ; SE=211) were significantly larger than female home ranges (mean 170 km 2 ; Wilcoxon-Mann-Whitney; P=0.001) and encompassed or included parts of up to five different females. Home range sizes of reproducing (170 km 2 ; SE=51) and barren (171 km 2 ; SE=63) adult females did not differ. Wolverines in Scandinavia exhibit intrasexual territoriality, with male home ranges totally exclusive and female home ranges either exclusive or with little home range overlap. Overlap between wolverine territories is most likely explained by intrasexual tolerance and kinship.

“…Site fidelity for adult birds and mammals is usually associated with successful breeding (Dahl and Willebrand 2005;Hoover 2003;Matthiopoulos et al 2005;Pomeroy et al 1994Pomeroy et al , 2000Sedgwick 2004;Thorstrom et al 2001). Specifically, it has been shown that territorial birds are more likely to continue to use the same territory if there were successful reproducing in the previous year.…”

Dispersal Patterns in Tarsius spectrum

One of the most widely accepted explanations for the difference in the sex bias between mammals and birds is that male-biased dispersal in mammals is due to the preponderance of polygynous mating systems exhibited by this class, whereas birds are predominantly monogamous. Spectral tarsiers (Tarsius spectrum) are unusual in that they exhibit variation in its mating system. Although the majority of spectral tarsier groups are monogamous, ca. 15% are polygynous. If mating system influences dispersal, then I predicted that the polygynous groups would exhibit male biased dispersal whereas I predicted that the dispersal patterns of the monogamous groups would be analogous to that exhibited by birds, specifically female biased. Alternatively, I hypothesized that ecological variation may influence dispersal habits in this species. Specifically, I predicted that polygynous groups would exhibit greater habitat quality than monogamous groups. The 2 hypotheses are not mutually exclusive. On the basis of 14 individuals birdbanded between 1994 and 1999, I determined that individuals of both sexes were equally likely to disperse (males, n= 5; females, n=9). Males dispersed twice as far as females did. The mean dispersal distance for males was 660 m, and for females it was 266 m. Females (77%) were more likely to form a territory adjacent to the parental territory than were males (20%). Individuals exhibited relatively high amounts of site fidelity (86%) that were related to physical characteristics of the sleeping site. Adults that dispersed a second time (n=4) initially resided in trees that were shorter and had a smaller diameter-atbreast height than the trees of individuals that exhibited site fidelity. The results of my study partly support the parental mating system hypothesis and also support the habitat quality hypothesis.
