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 Chemical Quality of Water and The Hydrologic Cycle Book in PDF, ePub and Kindle
This newly published book is an organized collection of papers dealing with changes in the quality of water as it moves through the world's hydrologic cycle-from the sea, lakes, and rivers-to its hydrosphere and then back to earth as precipitation, where the water again percolates through the soil or falls on the ocean, rivers, or lakes. (Changes that occur are physical, chemical, and biological.) Though chapters discuss results of specific lab or field experiments which in themselves have value for the scientist, focus is on processes involved. Many general concepts of water quality are provided in this cohesively organized book.
