This book was released on 2013 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stocking exotic trout species in high mountain lakes was a common practice in Rocky Mountain Lakes in the 20th century. Currently, restoration action to remove trout populations favours the conservation of native food webs. Meanwhile, little is known about the self-sustaining trout populations, particularly in our study area. We assessed impacts of stocking trout on naturally fishless foodwebs of mountain lakes. Results were applied to management goals in Waterton Lakes National Park. A comparison of mean abundances of zooplankton in fish and fishless lakes revealed differences in less than half the taxa encountered. Principle component analysis did not show an association between zooplankton community structure and fish presence. Paleolimnological analyses suggested an increase in relative abundance of large-bodied cladocerans, but statistical power was low. The results show the importance of identifying explicit restoration objectives because impacts may not be compelling. If restoration by trout eradication is pursued, demographic characteristics can aid in selecting which populations are more easily depleted by gillnetting. We used generalized linear models to examine four population characteristics associated with population decline: 1) catch per unit effort (CPUE), 2) proportion of females, 3) proportion of mature individuals and 4) length of mature individuals. There were significant differences between populations in CPUE and length at maturity, but not on the proportion of females or mature individuals. We thus incorporated the former characteristics into a basic assessment system and ranked the 11 salmonid populations by their susceptibility to eradication. We presented a simple yet meaningful step in facilitating management actions commonly constrained by a lack of biological knowledge.

Download or read book Ecosystems of California written by Harold Mooney and published by Univ of California Press. This book was released on 2016-01-19 with total page 1008 pages. Available in PDF, EPUB and Kindle. Book excerpt: This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.

Download or read book High Mountain Conservation in a Changing World written by Jordi Catalan and published by Springer. This book was released on 2017-08-03 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides case studies and general views of the main processes involved in the ecosystem shifts occurring in the high mountains and analyses the implications for nature conservation. Case studies from the Pyrenees are preponderant, with a comprehensive set of mountain ranges surrounded by highly populated lowland areas also being considered. The introductory and closing chapters will summarise the main challenges that nature conservation may face in mountain areas under the environmental shifting conditions. Further chapters put forward approaches from environmental geography, functional ecology, biogeography, and paleoenvironmental reconstructions. Organisms from microbes to large carnivores, and ecosystems from lakes to forest will be considered. This interdisciplinary book will appeal to researchers in mountain ecosystems, students and nature professionals. This book is open access under a CC BY license.
