Book Competition Between Non native Brook Trout and Coho Salmon in the Elwha River  WA During Dam Removal

Download or read book Competition Between Non native Brook Trout and Coho Salmon in the Elwha River WA During Dam Removal written by Emily Thornton and published by . This book was released on 2015 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The removal of two dams on the Elwha River, WA is the largest dam removal project in US history. A major goal of this project is to restore historically abundant populations of Pacific salmon to the river, so it is important to know if competition between resident and anadromous species could inhibit salmon recolonization. We investigated competitive interactions in laboratory streams to determine how species, size, and group size affected competitive dominance and determined the level of habitat and prey resource use overlap to indicate the potential for competition in reaches of the Elwha River. Coho salmon were competitively dominant over brook trout regardless of size difference or group size, and will likely outcompete brook trout in the wild if resources become limited. Prey resource use overlap indicated potential for competition in sympatric areas, but density and distribution patterns did not suggest that competition was occurring at the reach scale.

Book Salmonine Introductions to the Laurentian Great Lakes

Download or read book Salmonine Introductions to the Laurentian Great Lakes written by Stephen Scott Crawford and published by NRC Research Press. This book was released on 2001 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication provides an historical review and evaluation of documented ecological effects associated with salmonine introductions to the Laurentian Great Lakes. The introduction of salmonines to the Great Lakes date back to the 1870s, when natural populations of native salmonines in the Great Lakes were in severe decline. Using established evaluation protocols, it was determined that there is evidence of significant ecological effects in six different categories: (1) diseases and parasites, (2) predation on native species, (3) competition for limiting resources, (4) genetic alteration, (5) environmental alteration and (6) community alteration. Taken together, this body of evidence supports the conclusion that the ongoing introduction of non-native salmonines poses an ecologically-significant risk to the Great Lakes ecosystem and its native organisms, and that the introductions should be terminated.

Book Ecology  behaviour and conservation of the charrs  genus Salvelinus

Download or read book Ecology behaviour and conservation of the charrs genus Salvelinus written by Pierre Magnan and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salvelinus species are one of the most thoroughly studied groups of fishes. Many reasons explain this intense interest in charr biology. Charrs have a Holarctic distribution encompassing many Asian, North American, and European countries and occupy diverse marine and freshwater environments. Furthermore, the current distribution of charr includes areas that were directly influenced by climate and topographic change associated with the many Pleistocene glaciations. Undoubtedly, these conditions have promoted much of the tremendous morphological, ecological, and genetic variability and plasticity within Salvelinus species and they make charr very good models to study evolutionary processes 'in action'. Many charr species also exhibit demographic characteristics such as slow growth, late maturity, and life in extreme environments, that may increase their susceptibility to extinction from habitat changes and overexploitation, especially in depauperate aquatic habitats. This vulnerability makes understanding their biology of great relevance to biodiversity and conservation. Finally, charr are of great cultural, commercial, and recreational significance to many communities, and their intimate linkage with human societies has stimulated much interest in this enigmatic genus. This volume comprises a selection of papers presented at the fourth International Charr Symposium held in Trois-Rivières (Québec, Canada), from 26 June to 1 July 2000. It includes 31 papers on ecological interactions and behaviour, trophic polymorphism, movement and migration, ecophysiology and evolutionary genetics, ecological parasitology, environmental stress and conservation. These studies cannot cover all recent developments in the ecology, behaviour and conservation of Salvelinus species, but collecting them into a special volume should bring attention to current research on this important genus and stimulate further work on Salvelinus species.

Available in PDF, EPUB and Kindle. Book excerpt: As the vast expanses of natural forests and the great populations of salmonids are harvested to support a rapidly expanding human population, the need to understand streams as ecological systems and to manage them effectively becomes increasingly urgent. The unfortunate legacy of such natural resource exploitation is well documented. For several decades the Pacific coastal ecoregion of North America has served as a natural laboratory for scientific and managerial advancements in stream ecology, and much has been learned about how to better integrate ecological processes and characteristics with a human-dominated environment. These in sightful but hard-learned ecological and social lessons are the subject of this book. Integrating land and rivers as interactive components of ecosystems and watersheds has provided the ecological sciences with impor tant theoretical foundations. Even though scientific disciplines have begun to integrate land-based processes with streams and rivers, the institutions and processes charged with managing these systems have not done so successfully. As a result, many of the watersheds of the Pacific coastal ecoregion no longer support natural settings for environmental processes or the valuable natural resources those processes create. An important role for scientists, educators, and decision makers is to make the integration between ecology and con sumptive uses more widely understood, as well as useful for effective management.
