The space and habitat use patterns of the threatened Gaspé caribou (Rangifer tarandus caribou) were documented using telemetry. Between 1987 and 1992, 701 radiolocations were recorded, primarily for adult females (n = 28). Five habitats available to caribou (hardwood, immature, mature fir, mature spruce, alpine) are described and biomass of arboreal lichen, an important winter food source, is estimated. Regardless of sex and age, almost all locations (91%) were recorded within the limits of Gaspé Provincial Park. Home-range size of adult females averaged 148 km2 (convex polygon); 95% of adult female locations were within 107 km2 and 50% within 15 km2 (harmonic mean). Home-range sizes were small and did not vary seasonally or annually. Throughout the year caribou were located more frequently than expected at high elevations (> 915 m) and less frequently than expected at low elevations (0–685 m). Consequently, alpine habitat was used more frequently than expected. Caribou concentrated their activity in two distinct areas: the alpine plateaus of Mont Albert and Mont Jacques-Cartier. No caribou used both areas (with the exception of a lone female). These two caribou groups should be viewed as two subpopulations. The biomass of arboreal lichens was greatest in mature fir and spruce stands, with 50–60 kg/ha available at a height of 4 m. The altitudinal distribution of this resource may partly explain the strong selection of high-elevation sites made by caribou in winter. Our results also support the hypothesis that cow–calf groups remain at high elevations to reduce the risk of predation by coyotes (Canis latrans) and black bears (Ursus americanus). The proximity of mature forests and alpine habitat, at high elevations, in two areas of the park may explain the small extent of adult female home ranges and the segregation of Gaspé caribou into two groups.

Previous Summer

Winter radio-tracking of three African goshawks Accipiter tachiro showed that they each occupied well-wooded home ranges of at least 28 hectares. They perched and roosted mainly within densely foliaged trees and an adult female changed perches on average 4,7 times per hour. No crepuscular predation of bats was recorded, in contrast to regular summer predation on colonies of little free-tailed bats, Tadarida pumila, but winter emergence rates of these bats at dusk had dropped to < 5 of the previous summer. We predict that many accipiters will be regular predators of bats and that skewed sex ratios and high fecundity may be two means by which bats counter this predation.

Jaú, Zungaro jahu (Ihering, 1898), a large migratory catfish endemic to the rio da Prata basin, has a fragile conservation status and its ecology is poorly known. We radio-tracked a female jaú with a total length of 1.5 m that was passed upstream of Funil Dam, rio Grande, to describe its migratory movements, habitat use, linear home range, and diel activity. To track the fish, we made five tracking trips in the period from April, 2003 to January, 2004. In addition to the main body of Funil Reservoir, the fish also used a reservoir-river transition zone located in a branch of Funil Reservoir that flooded part of rio das Mortes. Most of the times, we found the fish in the former beds of streams flooded by the reservoir, at depths that ranged from 8-9 m in the reservoir-river transition zone to 18-21 m in Funil Reservoir. Linear home range of the fish was 31.4 km. The onset of activity occurred early in the evening, but we also detected daytime activity. The conclusion from our study was that the passed adult female jaú used reservoir habitats, migrated between the main body and the reservoir-river transition zone, preferred deep habitats, showed a relatively short home range, and had diurnal and nocturnal activities.

The effects of snowmobile traffic on the winter home-ranges, movements, and activity patterns, of White-tailed Deer (Odocoileus virginianus), were studied during two winters in northern Wisconsin. There were no significant differences in home-range size and habitat use of the Deer in areas with and without snowmobiling. However, snowmobiling caused some Deer to leave the immediate vicinity of the snowmobile trail. Deer were most affected when they were within 61 m of the snowmobile trail.

Terrestrial molluscs have declined globally, often as a result of habitat loss and fragmentation. Many land snails are poor dispersers and exist in isolated habitat patches. The Oregon forestsnail ( Allogona townsendiana (I. Lea, 1838)) coincides with the most densely populated region of British Columbia and is listed as endangered in Canada. To investigate the dispersal distances and habitat-use patterns of Oregon forestsnails, we tagged and tracked 21 adult snails at Langley, British Columbia, for up to 3 years (2005–2008). The maximum daily dispersal distance for a snail was 4.5 m and the maximum displacement that we observed for a snail was 32.2 m during 3 years. Snails occupied home-range areas of 18.4–404.4 m2, often overlapping both forest and meadow habitat. Their home-range sizes were smaller in habitats with high availability of stinging nettle ( Urtica dioica L.), which may be an indicator of high-quality habitat. Our results suggest that the Oregon forestsnail is a relatively sedentary species with limited dispersal ability in its adult stage. Although Oregon forestsnails are likely unable to colonize suitable habitat independently, remnant forest–meadow mosaic patches such as our study site provide valuable habitat for Oregon forestsnail, which are supplementary to large tracts of intact forest where most of their populations are found.
