Steenweg and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Mountain caribou (Rangifer tarandus caribou) are endangered across their range. The leading cause of their decline is increased apparent competition with other ungulates, mainly moose (Alces alces), because of increase in densities of predators such as wolves (Canis lupus). I tested some assumptions of, and evidence for, moose management as an approach to caribou recovery through the indirect reduction in wolf numbers. Increased hunting quotas drastically reduced moose densities in the Parsnip River Study Area of northern British Columbia, and I monitored 31 collared wolves during this decline. Despite wolf selection for vegetation types associated with moose and avoidance of areas selected by caribou, wolves occasionally forayed during snow-free months to elevations where caribou were more common. Wolf diets were comprised of >80% moose, with little caribou and other prey items. Annual dispersal rates of wolves increased compared to rates before moose reduction, and compared to a control study area. In systems where moose comprise the majority of wolf diets and caribou are at low densities, reductions in moose numbers may help to facilitate caribou recovery."--P. ii.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Woodland caribou (Rangifer tarandus caribou) have experienced population declines and local extirpations across North America. Human disturbance has caused caribou declines indirectly through changes to apparent competition dynamics within the predator-prey community. Apparent competition occurs as a negative indirect interaction between prey species, mediated by their direct interactions with a shared predator. I first review apparent competition, and show that across many endangered species including woodland caribou, human disturbance often causes an asymmetric tilt to the balance among prey species. Landscape disturbance such as forest harvest and energy development have created early seral-stage forests and linear features across the landscape of west-central Alberta. I studied the effects of landscape disturbance on the predator-prey dynamics of woodland caribou, wolves (Canis lupus) and other ungulate prey species in this region. I examined spatial patterns of resource selection by caribou, wolf predation risk, adult female caribou survival and, ultimately, population trend for 9 woodland caribou populations. Caribou avoided disturbance across all scales of resource selection, though avoidance of forestry cut-blocks was strongest at broad home range scales and avoidance of linear features was strongest at fine scales along caribou movement paths. Linear disturbances also increased predation risk by being selected as travel routes for hunting wolves, but did not increase the predation efficiency in terms of kills per time, as hypothesized. Rather, spatial changes in predation efficiency were largely driven by natural landscape heterogeneity. Avoidance by caribou and increased wolf predation risk in disturbed areas indicate functional habitat loss for caribou, yet these patterns alone do not necessarily imply a demographic impact. Spatial analysis of factors influencing adult female survival indicated that caribou resource selection was broadly correlated with survival, but also that wolf predation risk was an additional mortality risk beyond that perceived by caribou. This failure of caribou to non-ideally avoid predation risk may explain my final analysis showing significant and multi-year declines for all populations in west-central Alberta. Ultimately, if caribou conservation is to succeed, management must reverse the ultimate causes shifting the balance of apparent competition at both broad and fine scales across woodland caribou range.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Habitat alterations from anthropogenic disturbances across northeastern British Columbia have resulted in large-scale modifications to predator-prey dynamics. I used GPS collar locations and field data to quantify the responses of wolves (Canis lupus) and woodland caribou (Rangifer tarandus caribou) to the cumulative effects of industrial disturbance. I developed seasonal resource selection functions for caribou and count models of habitat occupancy for wolves. I also related wolf movements to caribou habitat and industrial features. Caribou occupying the boreal forest likely are more at risk from industrial developments. My results suggest that caribou occupying these ecosystems are subject to disturbance by human activity and a greater risk of spatial interactions with wolves. However, these relationships are complicated by the positive and negative responses of wolves to landscape change and the distribution of other prey and predator species."--P. i.
