Book excerpt: Beavers are represented by two extant species, the Eurasian beaver (Castor fiber) and the North American beaver (Castor canadensis); each has played a significant role in human history and dominated wetland ecology in the northern hemisphere. Their behaviour and ecology both fascinate and perhaps even infuriate, but seemingly never fail to amaze. Both species have followed similar histories from relentless persecution to the verge of extinction (largely through hunting), followed by their subsequent recovery and active restoration which is viewed by many as a major conservation success story. Beavers have now been reintroduced throughout Europe and North America, demonstrating that their role as a keystone engineer is now widely recognised with proven abilities to increase the complexity and biodiversity of freshwater ecosystems. What animals other than humans can simultaneously act as engineers, forest workers, carpenters, masons, creators of habitats, and nature managers? Over the last 20 years, there has been a huge increase in the number of scientific papers published on these remarkable creatures, and an authoritative synthesis is now timely. This accessible text goes beyond their natural history to describe the impacts on humans, conflict mitigation, animal husbandry, management, and conservation. Beavers: Ecology, Behaviour, Conservation, and Management is an accessible reference for a broad audience of professional academics (especially carnivore and mammalian biologists), researchers and graduate students, governmental and non-governmental wildlife bodies, and amateur natural historians intrigued by these wild animals and the extraordinary processes of nature they exemplify.
Book Synopsis Beaver Protection, Management, and Utilization in Europe and North America by : Peter E. Busher

This book was released on 2012-12-06 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: By the end of the 19th century both beaver species had been extirpated from large portions of their native ranges. The global decline in beaver populations was the direct re sult of exploitation by humans. Now, at the end of the 20th century, protection, manage ment, and reintroduction programs, coupled with a decline in the demand for beaver fur and other products, have allowed beaver populations to increase dramatically. Since bea vers actively modify their local environment their activities can conflict with human land use. Because of this, the beaver, once considered a unique and exotic component of wet lands, is now often considered a nuisance species. The history, as well as the current status, of beaver populations in Europe and North America provide insight into how con servation programs work, and into how humans and wildlife interact. The initial plenary lecture of the Euro-American Mammal Congress (July, 1998) was presented by Dr. Michael L. Rosenzweig, a professor at the University of Arizona. Dr. Rosenzweig discussed how humans have used and continue to use natural resources, in cluding wildlife and wildland. He provided evidence indicating that the current model of reservation conservation could not provide a long-term solution to the human-wild life/wildland conflict. Dr. Rosenzweig emphasized that what is required is a move away from purely exploitive activities (I would call this exploitive ecology) and the develop ment of a reconciliation ecology with wildlife.

Book Synopsis Influences of Beaver (Castor Canadensis) Activity on Ecology and Fish Assemblages of Dryland Streams by : Polly Peterkort Gibson

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 excerpt: "In response to climate warming, many species are shifting their distributions poleward, leading to the introduction of new species in Northern ecosystems. In the subarctic, woody shrubs have become more abundant and robust, water bodies have shifted from bedfast ice to floating ice regimes during winter, and melting permafrost has changed the topography and hydrology, facilitating pond development. Consequently, North American beaver (Castor canadensis) populations have begun entering the "greened" tundra ecosystem across North America. As a specialized rodent that modifies ecosystems by foraging woody vegetation and damming riverine habitats, completely altering forest composition and hydrology, it is important to understand the drivers and predictors of low arctic beaver establishment to inform conservation and wildlife management practices. In this thesis, I reviewed our existing understanding of which climatic, environmental, and vegetation factors influence beaver abundance, establishment, habitat selection, and foraging behaviour in the literature. This review highlighted that vegetation composition and traits, such as stem size and abundance, were considered as strong proxies for beaver forage and abundance, while climate, environment, and geomorphology increase the potential of habitat selection and establishment. Additionally, beavers' requirements change over time as the rodent completely alter their habitats and forest structure through ecosystem engineering. Therefore, it is crucial to distinguish between habitat characteristics before and after establishments to better understand the drivers of beaver colonization and abundance. Secondly, I aimed to address how these environmental and vegetation factors affect the functional adaptation of beavers over their Canadian distribution. Using geometric morphometrics, I tested the hypothesis that beaver skulls are locally adapted to their environment by relating environmental factors to functional traits in beaver skulls across Canada. I found that beaver functional morphology is significantly associated with vegetation and climate variables. Specifically, functional changes in the masticatory regions of the skull are related with changes in forest composition, biomass, ecozone, and climate, suggesting that beavers are adapted to their habitat based on selective foraging. These findings provide insight into the adaptive potential of newly established beavers in the sub-arctic to better predict future range shifts and provide information for future management practices"--

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.
