The Encyclopedia of Historic and Endangered Livestock and Poultry Breeds by Janet Vorwald Dohner Pdf
"The need to preserve farm animal diversity is increasingly urgent, says the author of this definitive book on endangered breeds of livestock and poultry. Farmyard animals may hold critical keys for our survival, Jan Dohner warns, and with each extinction, genetic traits of potentially vital importance to our agricultural future or to medical progress are forever lost."--BOOK JACKET.
Large Herbivore Ecology, Ecosystem Dynamics and Conservation by Kjell Danell,Roger Bergström,Patrick Duncan,John Pastor Pdf
Most large herbivores require some type of management within their habitats. Some populations of large herbivores are at the brink of extinction, some are under discussion for reintroduction, whilst others already occur in dense populations causing conflicts with other land use. Large herbivores are the major drivers for forming the shape and function of terrestrial ecosystems. This 2006 book addresses the scientifically based action plans to manage both the large herbivore populations and their habitats worldwide. It covers the processes by which large herbivores not only affect their environment (e.g. grazing) but are affected by it (e.g. nutrient cycling) and the management strategies required. Also discussed are new modeling techniques, which help assess integration processes in a landscape context, as well as assessing the consequences of new developments in the processes of conservation. This book will be essential reading for all involved in the management of both large herbivores and natural resources.
Rare British Breeds is a book inspired by the Rare Breed Survival Trust Watchlist, which is published annually, listing the species of sheep, cattle, horses, pigs, goats and poultry (chickens, turkeys, ducks and geese) that are endangered in the United Kingdom. This information is gathered from breed societies and lists the number of breeding females alive, along with their conservation status. Each species, regardless of their origin, is unique to the UK, either through cross breeding or by evolution. There are good reasons for wanting to keep these breeds alive; not just the genetic makeup of these creatures which means many are able to survive and thrive in very formidable conditions - a prerequisite for enduring possible future environmental disasters. Once gone, these genes will never be able to be replaced. They have taken thousands of years to develop. The book looks at the history of every breed, with their evolutionary roots, development over time, exportation, cross breeding and changing relationship to mankind as farming techniques react to societal shifts. Their particular physical characteristics such as meat, wool, milk, eggs or ability to pull great weights are discussed as well as their conservation status and the national and international efforts being made to ensure their survival.

Introduced Mammals of the World by John L Long Pdf
Winner in the Scholarly Reference section of the 2004 Australian Awards for Excellence in Educational Publishing. Introduced Mammals of the World provides a concise and extensive source of information on the range of introductions of mammals conducted by humans, and an indication as to which have resulted in adverse outcomes. It provides a very valuable tool by which scientists can assess future potential introductions (or re-introductions) to avoid costly mistakes. It also provides tangible proof of the need for political decision makers to consider good advice and make wise and cautious decisions. Introduced Mammals of the World also provides a comprehensive reference to students of ecological systems management and biological conservation. This book is a companion volume to Introduced Birds of the World, by the same author, published in 1981, and which remains the premier text of its kind in the world more than twenty years after it was published. Introduced Mammals of the World provides the most comprehensive account of the movement of mammals around the world providing details on the date(s) of introduction, the person/agency responsible, the source populations, the location(s) of release, the fate of the introductions, and the impact if known, for over 300 species of mammal.
In July 1935, Robert Atkinson and John Ainslie set out on an ornithological search for the rare Leach's Fork-tailed Petrel. Their quest was to last for twelve years and took them from their Oxford base to many of the remote and often deserted islands off the north-west coast of Scotland. Island Going is the account of their adventure. Not only is it packed with marvellous descriptions of the wildlife and landscapes of the islands as well as the journey itself, it also paints a vivid portrait of the way of life of the islanders and their history and traditions.

Stability in Model Populations by Laurence D. Mueller,Amitabh Joshi Pdf
Reviewing the general theory of population stability, this text critically analyzes techniques for inferring whether a given population is in balance or not. It goes on to show how rigorous empirical research can reveal both the proximal causes of stability and its most evolutionary cases.
KE-RA-ME-JA by Dimitri Nakassis,Joann Gulizio,Sarah A. James Pdf
The title of this volume, ke-ra-me-ja in Linear B, was chosen because it means ñpotterî (????????, from Greek ???????, ñpotterÍs clayî) and combines two major strands of Cynthia ShelmerdineÍs scholarship: Mycenaean ceramics and Linear B texts. It thereby signals her pioneering use of archaeological and textual data in a sophisticated and integrated way. The intellectual content of the essays demonstrate not only that her research has had wide-ranging influence, but also that it is a model of scholarship to be emulated.
