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.

Available in PDF, EPUB and Kindle. Book excerpt: Hardly a day goes by without news of the extinction or endangerment of yet another animal species, followed by urgent but largely unheeded calls for action. An eloquent denunciation of the failures of Canada’s government and society to protect wildlife from human exploitation, Max Foran’s The Subjugation of Canadian Wildlife argues that a root cause of wildlife depletions and habitat loss is the culturally ingrained beliefs that underpin management practices and policies. Tracing the evolution of the highly contestable assumptions that define the human–wildlife relationship, Foran stresses the price wild animals pay for human self-interest. Using several examples of government oversight at the federal, provincial, and territorial levels, from the Species at Risk Act to the Biodiversity Strategy, Protected Areas Network, and provincial management plans, this volume shows that wildlife policies are as much – or more – about human needs, priorities, and profit as they are about preservation. Challenging established concepts including ecological integrity, adaptive management, sport hunting as conservation, and the flawed belief that wildlife is a renewable resource, the author compels us to recognize animals as sentient individuals and as integral components of complex ecological systems. A passionate critique of contemporary wildlife policy, The Subjugation of Canadian Wildlife calls for belief-change as the best hope for an ecologically healthy, wildlife-rich Canada.

Available in PDF, EPUB and Kindle. Book excerpt: While tropical rainforests have received much conservation attention and support for their protection, temperate and boreal rainforests have been largely overlooked. Yet these ecosystems are also unique, supporting rainforest communities rich in plants and wildlife and containing some of the most massive trees on Earth. Temperate and Boreal Rainforests of the World brings together leading scientists from around the world to describe the ecology and conservation of these lesser-known rainforests in an attempt to place them on par with tropical rainforests in conservation efforts. The book summarizes major scientific findings presents new computer models that were used to standardize rainforest definitions identifies regions previously not widely recognized as rainforest provides the latest estimates on rainforest extent and degree of protection explores conservation strategies The book ends with a summary of the key ecological findings and outlines an ambitious vision of how we can conserve and manage the planet's remaining temperate and boreal rainforests in a truly ecological way that is better for nature, the climate, and ultimately our own welfare. Temperate and Boreal Rainforests of the World is a call to action for an accord to protect the world's rainforests. It offers a global vision rooted in ecological science but written in common language useful for governments, decision makers, and conservation groups concerned about the plight of these remarkable forests.

Download or read book Trophic Cascades written by John Terborgh and published by Island Press. This book was released on 2013-06-25 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trophic cascades—the top-down regulation of ecosystems by predators—are an essential aspect of ecosystem function and well-being. Trophic cascades are often drastically disrupted by human interventions—for example, when wolves and cougars are removed, allowing deer and beaver to become destructive—yet have only recently begun to be considered in the development of conservation and management strategies. Trophic Cascades is the first comprehensive presentation of the science on this subject. It brings together some of the world’s leading scientists and researchers to explain the importance of large animals in regulating ecosystems, and to relate that scientific knowledge to practical conservation. Chapters examine trophic cascades across the world’s major biomes, including intertidal habitats, coastal oceans, lakes, nearshore ecosystems, open oceans, tropical forests, boreal and temperate ecosystems, low arctic scrubland, savannas, and islands. Additional chapters consider aboveground/belowground linkages, predation and ecosystem processes, consumer control by megafauna and fire, and alternative states in ecosystems. An introductory chapter offers a concise overview of trophic cascades, while concluding chapters consider theoretical perspectives and comparative issues. Trophic Cascades provides a scientific basis and justification for the idea that large predators and top-down forcing must be considered in conservation strategies, alongside factors such as habitat preservation and invasive species. It is a groundbreaking work for scientists and managers involved with biodiversity conservation and protection.

Download or read book Foraging Ecology of Woodland Caribou in Boreal and Montane Ecosystems of Northeastern British Columbia written by Kristin Denryter and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Woodland caribou (Rangifer tarandus caribou) are an iconic species of boreal and montane ecosystems, but many populations are declining due to habitat alteration and associated changes in predator-prey dynamics. Summer forage, however, influences lactation, juvenile growth, pregnancy, and survival, thereby affecting individuals and populations. I used tame caribou (of three nutritional classes - lactating, non-lactating, yearling) as a habitat assessment tool, at 135 sites across northeastern British Columbia, to determine: food habits and selection; dry matter intake rates; diet quality; and daily nutrient intakes. My goal was to assess the suitability of nutritional resources in boreal and montane plant communities to support energy and protein requirements of caribou during summer. Caribou were highly selective foragers. Deciduous shrubs were the primary summer forage of caribou; forbs, lichens, and mushrooms were secondary dietary items. Intake rates by caribou increased with increasing bite masses and quantities of accepted forage biomass (vegetation species used proportionately more than or equal to availability). Caribou achieved highest intakes at sites with an abundance of selected deciduous shrubs (e.g., willow-alpine sites, young forests) that afforded large bite masses, whereas lowest intakes occurred where mean bite masses were small (e.g., dry alpine, nutrient-poor forests). Dietary digestible energy (DE) and protein (DP) content, intake rates, and foraging time varied across plant communities and among nutritional classes. Caribou increased foraging time, but could not compensate for low intake rates and some plant communities failed to provide caribou with adequate nutrient intakes to support nutritional demands for lactation and maintenance of body mass. Although highest nutrient intakes were associated with productive sites, predation risk and disturbance may constrain the nutritional benefits caribou can acquire from these sites. In a pilot study, I mapped foodscapes of DE and DP intakes for a herd of free-ranging boreal caribou. Caribou did not select for nutrient intakes, but other factors including food quantity, predation risk, and accuracy of spatial data layers, may have confounded my ability to isolate the role of nutrition in habitat selection. Insights from this study into the nutritional ecology of caribou during summer can better inform caribou conservation and management.
