This well-illustrated book highlights freshwater mussels' fabulous diversity, amazing array of often bizarre ecological adaptations and their dire conservation plight. Summarizing and synthesizing historical and contemporary information as well as original research and analysis, the book describes the diverse array of mussel life history strategies and builds a cohesive narrative culminating in the development of explicit frameworks to explain pervasive patterns in mussel ecology. The fascinating and colorful role of mussels in human society is also described in detail, including the little-known pearl button industry of the early 1900s and the wild and often violent shell harvest of the 1990s. The final chapter details humans' efforts to save these fascinating animals and gives a prognosis for the future of the North American fauna. The book provides the first comprehensive review of mussel ecology and conservation for scientists, natural resource professionals, students and natural history enthusiasts.
Synthesizes the ecology and natural history of North American freshwater mussels for scientists, natural resource professionals, students and natural history enthusiasts.
A global rewilding journey, exploring innovative and eye-opening projects led by passionate conservationists. Rewilding is a radical new approach to wildlife conservation that offers remarkable potential. If conservation seeks to preserve what remains and stave off further decline, rewilding goes further, seeking to restore entire ecosystems. It involves a spectrum of conservation options; at one end is a 'passive' approach prioritising ecological restoration – in essence, leaving land to recover naturally. At the other is what might be termed 'active' rewilding, where habitats are actively restored and keystone species reintroduced to quicken the process of recovery. The stakes are high in active rewilding. Large mammal translocations and wildlife corridors running through densely populated areas are high-risk, high-reward initiatives. In this timely and exciting contribution to a wider conversation about our relationship with the natural world, wildlife journalist Millie Kerr takes readers on a global journey of discovery. She considers the practicalities and possibilities of ecological restoration around the world, while exploring first-hand some of the most ambitious undertakings occurring today, many of which involve species reintroductions in the Global South. Wilder details the return of jaguars to an Argentinian national park, the first-ever pangolin reintroduction project in South Africa, and the ways in which giant tortoises are aiding the recovery of ecosystems throughout the Galápagos Islands, among many others. At an urgent moment in the international fight against biodiversity loss, Wilder's message is one of innovation and optimism. By focusing on conservation success stories and showing that there are bands of determined conservationists fighting for a better future, Wilder inspires us all to become part of the solution.
Readers familiar with the first three editions of Ecology and Classification of North American Freshwater Invertebrates (edited by J.H. Thorp and A.P. Covich) will welcome the comprehensive revision and expansion of that trusted professional reference manual and educational textbook from a single North American tome into a developing multi-volume series covering inland water invertebrates of the world. The series entitled Thorp and Covich's Freshwater Invertebrates (edited by J.H. Thorp) begins with the current Volume I: Ecology and General Biology (edited by J.H. Thorp and D.C. Rogers), which is designed as a companion volume for the remaining books in the series. Those following volumes provide taxonomic coverage for specific zoogeographic regions of the world, starting with Keys to Nearctic Fauna (Vol. II) and Keys to Palaearctic Fauna (Vol. III). Volume I maintains the ecological and general biological focus of the previous editions but now expands coverage globally in all chapters, includes more taxonomic groups (e.g., chapters on individual insect orders), and covers additional functional topics such as invasive species, economic impacts, and functional ecology. As in previous editions, the 4th edition of Ecology and Classification of North American Freshwater Invertebrates is designed for use by professionals in universities, government agencies, and private companies as well as by undergraduate and graduate students. - Global coverage of aquatic invertebrate ecology - Discussions on invertebrate ecology, phylogeny, and general biology written by international experts for each group - Separate chapters on invasive species and economic impacts and uses of invertebrates - Eight additional chapters on insect orders and a chapter on freshwater millipedes - Four new chapters on collecting and culturing techniques, ecology of invasive species, economic impacts, and ecological function of invertebrates - Overall expansion of ecology and general biology and a shift of the even more detailed taxonomic keys to other volumes in the projected 9-volume series - Identification keys to lower taxonomic levels
David Thompson’s Travels is one of the finest early expressions of the Canadian experience. The work is not only the account of a remarkable life in the fur trade but an extended meditation on the land and Native peoples of western North America. The second in a planned three volumes of Thompson’s writings, this edition completes the great surveyor and fur trader’s spirited autobiographical narrative. In the 1848 Travels, Thompson describes his most enduring historical legacy - the extension of the fur trade across the Continental Divide between 1807 and 1812. During these years he established several Nor’wester trading posts, made contact with the tribal peoples of the Columbia Plateau, and tirelessly mapped the lands he traversed, all the time striving westward toward the Pacific. The tale culminates with Thompson’s historic arrival at the mouth of the Columbia in July 1811. Like its companion Volume 1, this work presents an entirely new transcription by William Moreau of Thompson’s manuscript, and is accompanied by an introductory essay placing the author in his historical and intellectual context. Extensive critical annotations, a biographical appendix, and historical and modern maps, make this the definitive collection of Thompson’s works, and bring one of North America’s most important travelers and surveyors to a new generation of readers.
