“…Siblings of different litters remaining in the mother's home range show that the dispersal of an individual is not associated with the birth of another litter. This lack of immediate dispersal of older litter mates is similar to what has been observed in lynx (Lynx pardinus) (Ferreras et al 2004), but different to most other solitary cats, where dispersal is synched with the rearing of a new litter (Smith 1993, Maehr et al 2002.…”

Abstract:Home range shifts prior to natal dispersal have been rarely documented, yet the events that lead a subadult to abandon a portion of its home range and venture into unfamiliar territories, before eventually setting off to look for a site to reproduce, are probably related to the causes of dispersal itself. Here, we used a combination of manual radio-tracking and an Automated Radio Telemetry System to continuously study the movements of a subadult male ocelot (Leopardus pardalis), a solitary carnivore with sex-biased dispersal, on Barro Colorado Island, Panama, for 18 months from May 2003 through October 2004. The subadult ocelot's parents were also radio-tracked to record possible parent-offspring interactions within their home ranges. At the age of ca. 21 months the subadult gradually began to shift its natal home range, establishing a new one used until the end of the study, in an area that had previously been used by another dispersing subadult male. Only three parent-offspring interactions were recorded during the four months around the time the range-shift occurred. The apparent peaceful nature of these encounters, along with the slow transition out of a portion of his natal home range, suggest the subadult was not evicted from his natal area by his parents. The timing of the shift, along with the subadult's increase in weight into the weight range of adult ocelots four months after establishing the new territory, suggests that predispersal home range shifts could act as a low risk and opportunistic strategy for reaching adult size, while minimizing competition with parents and siblings, in preparation for an eventual dispersal into a new breeding territory.

“…This is the case particularly in areas where human development and areasensitive wildlife populations interface (Meegan and Maehr 2002;Maehr et al 2002;Harveson et al 2007). Exurban development is increasing throughout much of the developed world (Hilty et al 2006).…”

Space and habitat use of moose in southwestern Sweden

et al. 2010

Increasingly, wildlife managers and land managers are challenged to maintain the viability of large mammal populations. Although the moose (Alces alces) is an ecologically, economically, and culturally important ungulate species found throughout most of Sweden, little is known about its ecology throughout the southern part of the country. We collected baseline ecological data on spatial and habitat use patterns in urbanized southwestern Sweden by fitting 22 adult moose (13 F, nine M) with global positioning system (GPS) radio collars. Home range size of cows did not differ among seasons (P>0.10); however, bulls had larger home ranges during fall than all other seasons (P<0.010). Mean home range size of males during fall and spring was larger than females during any season (P<0.010). We used a Euclidean distance-based approach to analyze multi-scale habitat selection by moose. Moose of both sexes and during all seasons selected boreal forest and mires when establishing a home range (P<0.10). Moose had seasonal differences in habitat selection within their home range (P0.001), and generally selected clear-cuts and early successional forests, mature coniferous forests, and glades, but avoided agricultural areas and open water. Habitat and space use characteristics of moose in our urbanizing study area were similar to characteristics reported for moose in forest-dominated landscapes of Fennoscandia.

“…The fact that cougars are efficient colonizers (Nero and Wrigley 1977) with large home ranges (Seidenticker et al 1973) ensures that the debate about the potential presence of animals in eastern Canada continues. Reported cou gars may be transients, escapees or members of a remnant population, but they could act as dispersers for the (re)establishment of viable populations in eastern Canada (Scott 1998 * ; Maehr et al 2002). The determination of these cats' origin should help define the protection status they deserve.…”

“…Weaver et al (1996) argued that conflicts for resources and land uses may be the main causes of most Cougar extirpation in North America. Previous studies across North America have indicated that road density, urbanization, agriculture and timber harvesting may also limit Cougar expansion (van Dyke et al 1986;Maehr et al 2002;Taylor et al 2002;Dickson et al 2005).…”
