Última Response of Wolves to Corridor Restoration and Human Use Management Ecology and Society Shepherd, Brenda; Jasper National Park; Brenda.Shepherd@pc.gc.ca; Whittington, Jesse; Banff National Park; Jesse.Whittington@pc.gc.ca. Corridor restoration is increasingly being used to connect habitat in mountainous areas where rugged topography and increasing human activity fragment habitat. Wolves (Canis lupus) are a conservation priority because they avoid areas with high levels of human use and are ecologically important predators. We examined how corridor restoration through a golf course changes the distribution of wolves and their prey in Jasper National Park, Alberta, Canada. We followed and recorded wolf paths in the snow both within the corridor and in the surrounding landscape before and after a corridor was re-established. Track transects were used to estimate prey abundance and snow depths, and trail counters measured human activity. We compared resources on wolf paths to...

Ano: 2006 Winter Responses of Forest Birds to Habitat Corridors and Gaps Ecology and Society St. Clair, Colleen Cassady; University of Alberta; cstclair@ualberta.ca; Hannon, Susan; University of Alberta; Sue.Hannon@ualberta.ca. Forest fragmentation and habitat loss may disrupt the movement or dispersal of forest-dwelling birds. Despite much interest in the severity of these effects and ways of mitigating them, little is known about actual movement patterns in different habitat types. We studied the movement of wintering resident birds, lured by playbacks of mobbing calls, to compare the willingness of forest birds to travel various distances in continuous forest, along narrow corridors (fencerows), and across gaps in forest cover. We also quantified the willingness of Black-capped Chickadees (Poecile atricapillus) to cross gaps when alternative forested detour routes were available. All species were less likely to respond to the calls as distance increased to 200 m, although...

Ano: 1998 Cumulative Effects of Barriers on the Movements of Forest Birds Ecology and Society St. Clair, Colleen Cassady; University of Alberta; cstclair@ualberta.ca. Although there is a consensus of opinion that habitat fragmentation has deleterious effects on animal populations, primarily by inhibiting dispersal among remaining patches, there have been few explicit demonstrations of the ways by which degraded habitats actually constrain individual movement. Two impediments are primarily responsible for this paucity: it is difficult to separate the effects of habitat fragmentation (configuration) from habitat loss (composition), and conventional measures of fragmented habitats are assumed to be, but probably are not, isotropic. We addressed these limitations by standardizing differences in forest cover in a clearly anisotropic configuration of habitat fragmentation by conducting a homing experiment with three species...
