Book excerpt: This is the first comprehensive look at the taxonomy, life history, and conservation status of the world's trout and char. These are fascinating and beautiful fish that rate high for the angler as well as for tourist and recreational economies. Trout and char also play key roles in the ecology of many lake and river systems around the world. Trout and char are abundant in many regions, but most native species are on the decline. Some are classified as vulnerable, threatened, or endangered. Because of their widespread stocking in regions where they are not native, some trout and char also are the cause for threats to other native species. Loss of habitat, an expanding human population, and rapid climate change are challenging their future as streams warm and waters become more variable in their flows. This book examines trout and char from all these perspectives. Early chapters explore the unique diversity and life history aspects of trout and char and provide information on the taxonomy and systematics while also detailing some of unique life histories. New information is presented about species diversity and distributions by country. Summary chapters explore significant conservation and management challenges of broad interest to scientists, resource managers, anglers, and interested public. Trout and Char of the World end s with a series of essays exploring the future of trout and char over the next 50 years. Trout and Char of the World will be a primary resource for trout and char biologists, conservationists, and anglers in the many countries where trout and char are native or have been introduced, and a resource for anyone interested in learning more about the diversity and distribution of trout and char worldwide.--

Available in PDF, EPUB and Kindle. Book excerpt: We live in a changing world; one in which there is much concern and discussion about the topics of global change, loss of biodiversity, and increasing threats to the sustainability of ecosystems. The effects these changes may have on the environment have lead governments and sCientists to make predictions as to how soon changes might occur, where, and with what impact for large and small regions of the Earth. Along with this concern for change in various regions has come the need to understand the role of boundaries between these regions and between landscape elements. Much previous ecological research has dealt with processes within relatively homogeneous landscape units or even the collective characteristics of a composite landscape. Now, however, there is an appreciation that abiotic and biotic components move across heterogeneous landscapes and that the boundaries between these units take on important control functions in this dynamic spatial system. Furthermore, landscape boundaries (or ecotones) are important not only in satisfying life-cycle needs of many organisms, but generally are characterized by high biological diversity.

Download or read book Fishes and Forestry written by Thomas G. Northcote and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 800 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many species of fish occupying inland waters reside in watershedsthat were or still are surrounded by forests and are dependent inmajor ways upon such cover. The interactions between fishes andforests are complex, multifaceted, dynamic processes involving mostinland surface waters, forests, subsurface waters, geology andsoils, climate and its changes, and the biotic components of therelevant ecosystems. These interactions also include the aspects offorestry tied to human development, economics, population growthand even philosophies. Fishes and Forestry is truly a landmark publication. Theeditors, Professors Northcote and Hartman, have drawn together andcarefully edited chapters written by 56 scientists from around theworld, covering a vast wealth of information never before appearingwithin the covers of one book. Following an introductory chapter,this exceptional work is broadly divided into sections covering:the ecology of forests, streams, lakes and estuaries; fish biologyand ecology; forestry activities and their effects on aquaticsystems and fishes; 14 chapters covering examples of fish-forestryinteractions from around the world and a final section coveringmeans of effecting better fish-forestry interactions. Fishes and Forestry is an essential purchase for allthose involved in inland fisheries, forestry and their interaction,including fisheries scientists, fish biologists, ecologists,environmental scientists and forestry scientists. Libraries in alluniversities and research establishments where these subjects arestudied and taught should have several copies on their shelves.

Download or read book The Future of Fisheries Science in North America written by Richard J. Beamish and published by Springer Science & Business Media. This book was released on 2009-02-07 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fisheries science in North America is changing in response to a changing climate, new technologies, an ecosystem approach to management and new thinking about the processes affecting stock and recruitment. Authors of the 34 chapters review the science in their particular fields and use their experience to develop informed opinions about the future. Everyone associated with fish, fisheries and fisheries management will find material that will stimulate their thinking about the future. Readers will be impressed with the potential for new discoveries, but disturbed by how much needs to be done in fisheries science if we are to sustain North American fisheries in our changing climate. Officials that manage or fund fisheries science will appreciate the urgency for the new information needed for the stewardship of fish populations and their ecosystems. Research organizations may want to keep some extra copies for a future look back into the thoughts of a wide range of fisheries professionals. Fisheries science has been full of surprises with some of the surprises having major economic impacts. It is important to minimize these impacts as the demand for seafood increases and the complexities of fisheries management increase.
