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.

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.

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.

This book was released on 1994 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Study to determine the effects of beaver activity on water quality under conditions of winter ice cover and to contrast the water quality parameters from beaver ponds of different ages. From 30 November 1991 until 25 April 1992, weekly water samples were collected under snow and ice-cover from an old abandoned beaver pond and a new pond and their proximal streams in Catamaran Brook, a tributary of the Little Southwest Miramichi in central New Brunswick. Samples were analyzed for specific conductance, turbidity, apparent colour, dissolved oxygen, dissolved nitrate, and dissolved sulphate.

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.
