This book was released on 2015 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predation by grey wolves (Canis lupus) has been identified as an important cause of boreal woodland caribou (Rangifer tarandus caribou) mortality. Wolves have been hypothesized to use human-created linear features such as seismic lines, pipelines and roads to increase ease of movement resulting in higher kill rates. I tested if wolves select linear features and if they increase movement rates while travelling on linear features in northeastern Alberta and northwestern Saskatchewan using fine scale analyses with 5-minute GPS (Global Positioning System) locations from twenty-two wolves in 6 packs. In addition, I examined how the abundance and physical properties of linear features affects wolf selection of, and movement on, these features. Wolves selected all linear feature classes except for low-impact seismic lines in summer and trails in winter, with the magnitude of selection depending on season. In summer, compared to the surrounding forest, wolves travelled slower on low-impact seismic lines but 2 to 3 times faster on all other linear feature classes. In winter wolves travelled 2 to 3 times faster on conventional seismic lines, pipelines, roads and railways, but slower on low-impact seismic lines and transmission lines. In addition, increased average daily travelling speed while on linear features as well as increased proportion of steps spent travelling on linear features caused increased net daily movement rates, supporting that wolf use of linear features can increase their search distance. The selection of linear features by individual wolves was not related to linear feature density. In summer, linear features through uplands provided a greater increase in travelling speed relative to surrounding forest than wetlands, however this was opposite in winter. Furthermore, when on linear features, wolves selected and moved faster on linear features with shorter vegetation. Vegetation reaching a height beyond 1 m on linear features reduced movement by 23% in summer, whereas vegetation did not decrease travelling speed in winter until it exceeded 5 m. This knowledge can aid mitigation strategies by targeting specific features for reclamation and linear deactivation, such as conventional seismic lines and pipelines with vegetation regrowth less than 1 m, allowing for more effective use of conservation resources.

Available in PDF, EPUB and Kindle. Book excerpt: The present biodiversity crisis is rife with opportunities to make important conservation decisions; however, the misuse or misapplication of the methods and techniques of animal ecology can have serious consequences for the survival of species. Still, there have been relatively few critical reviews of methodology in the field. This book provides an analysis of some of the most frequently used research techniques in animal ecology, identifying their limitations and misuses, as well as possible solutions to avoid such pitfalls. In the process, contributors to this volume present new perspectives on the collection, analysis, and interpretation of data. Research Techniques in Animal Ecology is an overarching account of central theoretical and methodological controversies in the field, rather than a handbook on the minutiae of techniques. The editors have forged comprehensive presentations of key topics in animal ecology, such as territory and home range estimates, habitation evaluation, population viability analysis, GIS mapping, and measuring the dynamics of societies. Striking a careful balance, each chapter begins by assessing the shortcomings and misapplications of the techniques in question, followed by a thorough review of the current literature, and concluding with possible solutions and suggested guidelines for more robust investigations.

This book was released on 2012 with total page 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.

Book excerpt: This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.

This book was released on 2015 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dietary information of free-ranging animals is essential for understanding their ecology, conservation and management. Carnivore diet is most frequently estimated using morphological analysis of prey remains found in scats. However, genetic methods are becoming increasingly common and may identify prey parts that are unidentifiable with morphological methods (Symondson 2002). We developed an easy and accurate molecular approach to assess occurrence of prey species in the diet of free-living wolves (Canis lupus) and compared the results to analyses of prey hair in the same samples. The occurrence of DNA and hair remains for moose (Alces alces), woodland caribou (Rangifer tarandus caribou), deer (Odocoileus sp.), snowshoe hare (Lepus americanus) and American beaver (Castor canadensis) were compared in wolf scats from northeastern Alberta, Canada. Detection of any prey species was 1.34 times as likely with DNA analysis than with hair analysis. DNA analysis showed significantly higher occurrences of every prey species (p

Available in PDF, EPUB and Kindle. Book excerpt: Like wolf restoration activities in the West, the proposal to reintroduce wolves into the Adirondacks has generated intense public debate. The idea of returning top predators to settled landscapes raises complicated questions on issues ranging from property rights to wildlife management to obligations to present and future generations.Wolves and Human Communities brings together leading thinkers and writers from diverse fields -- including Timothy Clark, Daniel Kemmis, L. David Mech, Mary Midgley, Ernest Partridge, Steward T.A. Pickett, Joseph Sax, Rodger Schlickeisen, and others -- to address the complex ethical, biological, legal, and political concerns surrounding wolf reintroduction. Contributors specifically explore the social, cultural, and ecological values that come into play in the debate, as they examine: the views of stakeholders in the Adirondack decision historical trends in public perception of restoration the legal and policy context for species preservation, and the challenges to the current system of property law biological and political lessons learned from Yellowstone, Isle Royale, and the Great Lakes states the meaning of wildness, both in ourselves and the wolf The final chapter by Niles Eldredge takes the point of view of evolutionary time and ecological scale, challenging us to develop a new consciousness regarding our position in the natural world.Wolves and Human Communities offers a thought-provoking examination of interactions between human and wild communities, and represents an important contribution to debates over species reintroduction for policymakers, researchers, ecologists, sociologists, lawyers, ethicists, philosophers, and local residents.

Download or read book Recovery of Gray Wolves in the Great Lakes Region of the United States written by Adrian P. Wydeven and published by Springer Science & Business Media. This book was released on 2009-02-27 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, we document and evaluate the recovery of gray wolves (Canis lupus) in the Great Lakes region of the United States. The Great Lakes region is unique in that it was the only portion of the lower 48 states where wolves were never c- pletely extirpated. This region also contains the area where many of the first m- ern concepts of wolf conservation and research where developed. Early proponents of wolf conservation such as Aldo Leopold, Sigurd Olson, and Durward Allen lived and worked in the region. The longest ongoing research on wolf–prey relations (see Vucetich and Peterson, Chap. 3) and the first use of radio telemetry for studying wolves (see Mech, Chap. 2) occurred in the Great Lakes region. The Great Lakes region is the first place in the United States where “Endangered” wolf populations recovered. All three states (Minnesota, Wisconsin, and Michigan) developed ecologically and socially sound wolf conservation plans, and the federal government delisted the population of wolves in these states from the United States list of endangered and threatened species on March 12, 2007 (see Refsnider, Chap. 21). Wolf management reverted to the individual states at that time. Although this delisting has since been challenged, we believe that biological recovery of wolves has occurred and anticipate the delisting will be restored. This will be the first case of wolf conservation reverting from the federal government to the state conser- tion agencies in the United States.
