Book Synopsis Influences of Beaver (Castor Canadensis) Activity on Ecology and Fish Assemblages of Dryland Streams by : Polly Peterkort Gibson
Download or read book Influences of Beaver (Castor Canadensis) Activity on Ecology and Fish Assemblages of Dryland Streams written by Polly Peterkort Gibson and published by . This book was released on 2013 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: After near-extirpation in the early 20th century, beaver populations are increasing throughout many parts of North America. Simultaneously, there is an emerging interest in employing beaver activity for stream restoration in arid and semi-arid environments (collectively, `drylands'), where streams and adjacent riparian ecosystems are expected to face heightened challenges from climate change and human population growth. However, despite growing interest in reintroduction programs, surprisingly little is known about the ecology of beaver in dryland streams, and science to guide management decisions is often fragmented and incomplete. In my first chapter I systematically reviewed the literature addressing the ecological effects and management of beaver activity in drylands of North America, highlighting conservation implications, distinctions between temperate and dryland streams, and knowledge gaps. Well-documented effects of beaver activity in drylands include changes to channel morphology and groundwater processes, creation of perennial wetland habitat, and substantial impacts to riparian vegetation. However, many hypothesized effects lack empirical evidence, especially from dryland streams. One of the most important areas of uncertainty identified by this review is the influence of beaver activity on the proliferation and success of non-native species. Streams of the American Southwest support a highly endangered native fish fauna and abundant non-native fishes, and in my second chapter I investigated the hypothesis that beaver ponds in this region may lead to fish assemblages dominated by non-native species. I sampled fish assemblages within beaver ponds and within unimpounded stream reaches in the free-flowing upper Verde River basin, central Arizona. I found that although non-native fishes consistently outnumbered native species, this dominance was greater in pond than in stream assemblages. Multivariate analysis indicated that fish assemblages in beaver ponds were distinct from those in stream reaches, in both mainstem and tributary locations. Few native species were recorded within ponds, while some non-natives, notably green sunfish (Lepomis cyanellus) and western mosquitofish (Gambusia affinis) were abundant within ponds. Overall, this study provides evidence that, relative to unimpounded stream habitat, beaver ponds in the Verde River basin support abundant small-bodied non-native fishes, which could have negative impacts on co-occurring native fish populations.
Book Synopsis Plant Disturbance Ecology by : Edward A. Johnson
Download or read book Plant Disturbance Ecology written by Edward A. Johnson and published by Academic Press. This book was released on 2020-10-21 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Disturbance ecology continues to be an active area of research, having undergone advances in many areas in recent years. One emerging direction is the increased coupling of physical and ecological processes, in which disturbances are increasingly traced back to mechanisms that cause the disturbances themselves, such as earth surface processes, mesoscale, and larger meteorological processes, and the ecological effects of interest are increasingly physiological. Plant Disturbance Ecology, 2nd Edition encourages movement away from the informal, conceptual approach traditionally used in defining natural disturbances and clearly presents how scientists can use a multitude of approaches in plant disturbance ecology. This edition includes nine revised chapters from the first edition, as well new, more comprehensive chapters on fire disturbance and beaver disturbance. Edited by leading experts in the field, Plant Disturbance Ecology, 2nd Edition is an essential resource for scientists interested in understanding plant disturbance and ecological processes. Advances understanding of natural disturbances by combining geophysical and ecological processes Provides a framework for collaboration between geophysical scientists and ecologists studying natural disturbances Includes fully updated research with 5 new chapters and revision of 11 chapters from the first edition

Book Synopsis Ecological Regions of North America by :
Download or read book Ecological Regions of North America written by and published by . This book was released on 1997 with total page 92 pages. Available in PDF, EPUB and Kindle. 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.
Download or read book Saving the Dammed written by Ellen Wohl and published by Oxford University Press, USA. This book was released on 2019 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability of beavers to create an abundant habitat for a diverse array of plants and animals has been analyzed time and again. The disappearance of beavers across the northern hemisphere, and what this effects, has yet to be comprehensively studied. Saving the Dammed analyzes the beneficial role of beavers and their dams in the ecosystem of a river, focusing on one beaver meadow in Colorado. In her latest book, Ellen Wohl contextualizes North St. Vrain Creek by discussing the implications of the loss of beavers across much larger areas. Saving the Dammed raises awareness of rivers as ecosystems and the role beavers play in sustaining the ecosystem surrounding rivers by exploring the macrocosm of global river alteration, wetland loss, and the reduction in ecosystem services. The resulting reduction in ecosystem services span things such as flood control, habitat abundance and biodiversity, and nitrate reduction. Allowing readers to follow her as she crawls through seemingly impenetrable spaces with slow and arduous movements, Wohl provides a detailed narrative of beaver meadows. Saving the Dammed takes readers through twelve months at a beaver meadow in Colorado's Rocky Mountain National Park, exploring how beavers change river valleys and how the decline in beaver populations has altered river ecosystems. As Wohl analyzes and discusses the role beavers play in the ecosystem of a river, readers get to follow her through tight, seemingly impenetrable, crawl spaces as she uncovers the benefit of dams.
Book Synopsis Linking Species & Ecosystems by : Clive G. Jones
Download or read book Linking Species & Ecosystems written by Clive G. Jones and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: I was asked to introduce this volume by examining "why a knowledge of ecosys tem functioning can contribute to understanding species activities, dynamics, and assemblages." I have found it surprisingly difficult to address this topic. On the one hand, the answer is very simple and general: because all species live in ecosystems, they are part of and dependent on ecosystem processes. It is impossible to understand the abundance and distribution of populations and the species diversity and composition of communities without a knowledge of their abiotic and biotic environments and of the fluxes of energy and mat ter through the ecosystems of which they are a part. But everyone knows this. It is what ecology is all about (e.g., Likens, 1992). It is why the discipline has retained its integrity and thrived, despite a sometimes distressing degree of bickering and chauvinism among its various subdisciplines: physiological, be havioral, population, community, and ecosystem ecology.
Book Synopsis Potential Impacts of Beaver on Oil Sands Reclamation Success by : B. Eaton
Download or read book Potential Impacts of Beaver on Oil Sands Reclamation Success written by B. Eaton and published by . This book was released on 2013 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North American beaver (Castor canadensis) is a large semi-aquatic rodent that has played a central role in shaping the Canadian boreal landscape, and colonial Canadian history. Exploitation of North American beaver populations to supply the European hat industry spurred the westward expansion of European explorers and traders into the continental interior. With intensive unregulated harvest, beavers virtually disappeared across much of their range; though populations are recovering, the species is only about 10% as abundant as it was before the fur trade took its toll. As a result, much of the recent ecological history of the Canadian boreal forest has occurred in the absence of this keystone ecosystem engineer, and the ecological state that we perceive as natural is in many regions quite different than it was a century ago.
Book Synopsis The Eurasian Beaver Handbook by : Roisin Campbell-Palmer
Download or read book The Eurasian Beaver Handbook written by Roisin Campbell-Palmer and published by Pelagic Publishing Ltd. This book was released on 2016-08-15 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beavers are widely recognised as a keystone species which play a pivotal role in riparian ecology. Their tree felling and dam building behaviours coupled with a suite of other activities create a wealth of living opportunities that are exploited by a range of other species. Numerous scientific studies demonstrate that beaver-generated living environments that are much richer in terms of both biodiversity and biomass than wetland environments from which they are absent. Emerging contemporary studies indicate clearly that the landscapes they create can afford sustainable, cost-effective remedies for water retention, flood alleviation, silt and chemical capture. Beaver activities, especially in highly modified environments, may be challenging to certain land use activities and landowners. Many trialled and tested methods to mitigate against these impacts, including a wide range of non-lethal management techniques, are regularly implemented across Europe and North America. Many of these techniques will be new to people, especially in areas where beavers are newly re-establishing. This handbook serves to discuss both the benefits and challenges in living with this species, and collates the wide range of techniques that can be implemented to mitigate any negative impacts. The authors of this handbook are all beaver experts and together they have a broad range of scientific knowledge and practical experience regarding the ecology, captive husbandry, veterinary science, pathology, reintroduction and management of beavers in both continental Europe and Britain.

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The North American beaver (Castor canadensis) is one of the few extant mammals able to modify its surrounding landscape dramatically, often complicating its relationship with humans. However, the vast majority of research has been limited to north temperate regions, with almost no data regarding southern beaver populations. The focal point of this study was to understand the impact beaver impoundments on stream systems of warm temperate regions. Two sites in Thomasville, Georgia (Gatling Branch and Unnamed Creek) were selected for this study based on location, morphology, hydrology and active beaver populations. Sampling was conducted from November 2006 through April 2007, with April capturing the effects of extensive anthropogenic construction activities. For each system, two 100-m stretches, upstream and downstream of the beaver pond, and the pond proper were sampled. Measurements and/or samples included chemical / physical parameters (temperature, dissolved oxygen, specific conductivity and total suspended solids), macroinvertebrate communities and benthic organic matter storage. Statistical comparisons were made between compartments (upstream, downstream and pond), sampling periods and compartments relative to sampling period. During the pre-anthropogenic disturbance period, few parameters were longitudinally or temporally significant when compared between sampling compartment and sampling dates.
