The Behavior and Ecology of Pacific Salmon and Trout
Author: Thomas P. QuinnPublisher: UBC Press
ISBN: 0774842431
Category : Nature
Languages : en
Pages : 392
Book Description
The Behavior and Ecology of Pacific Salmon and Trout explains the patterns of mate choice, the competition for nest sites, and the fate of the salmon after their death. It describes the lives of offspring during the months they spend incubating in gravel, growing in fresh water, and migrating out to sea to mature. This thorough, up-to-date survey should be on the shelf of everyone with a professional or personal interest in Pacific salmon and trout. Written in a technically accurate but engaging style, it will appeal to a wide range of readers, including students, anglers, biologists, conservationists, legislators, and armchair naturalists.

Book Description
"The purpose of the symposium was to summarize BASIS research conducted during 2002 to 2006 and increase our understanding about how climate change will affect salmon growth and survival in the North Pacific Ocean. The symposium topics were: 1. Overviews of climate change, Bering Sea ecosystems, and salmon production. 2. Biological responses by salmon to climate and ecosystem dynamics, 2.1. Migration and distribution of salmon, 2.2. Food production and salmon growth, 2.3. Feeding habits and trophic interactions, 2.4. Production trends and carrying capacity of salmon"--Pref.

Book Description
A changing environment is not a new challenge for Pacific salmon. This group of fishes has proven resilient, persisting over millions of years while surviving massive changes in climate and physical habitats. There is therefore reason to believe that salmon will be able to adapt to the changes anticipated in association with global climate change. Indeed, the level of warming predicted for the coming century seems a surmountable challenge for salmon at the genus level. However, climate change is impacting and will continue to impact individual populations, driving marked changes in their ecology, abundance and life-histories. The distinction between species and population is important because the majority of ecological, cultural and economic values provided by salmon are manifest at local or regional scales and tied to specific populations, species and life-history types. Furthermore, it is typically at these scales that fisheries and fish habitats are managed. Although the influence of past climate variability on the productivity of salmon populations demonstrates sensitivity of these species to environmental change, unanticipated and unintuitive outcomes are possible given the complexity and diversity of the species and their life-histories. Understanding past variability and predicting future trajectories of salmon populations therefore requires an in-depth understanding of the mechanisms that link environmental change to population productivity. This information can help to ensure that fisheries management serves to increase resilience of salmon populations and avoids actions that amplify potential negative consequences of climate change. This dissertation seeks to contribute to the informed management of Pacific salmon in a warming world through development of theory and in-depth exploration of cases where salmon populations have responded to changing environments. Chapter 1 considers the underappreciated phenomenon of temporal selection in fisheries and its implications for climate adaptation by salmon and other fishes. Chapter 2 tests a series of hypotheses that link observed warming in Lake Iliamna, Alaska to changes in sockeye salmon life-history and productivity. Chapter 3 describes a novel pattern of adult mortality in spawning sockeye salmon and demonstrates that low streamflow can create habitat conditions under which density-dependent spawning failure may occur. Chapter 4 describes changes in reproductive timing of Cedar River, Washington sockeye salmon and examines the relative influence of natural and artificial selection on phenological change and climate change resilience. Collectively, this research demonstrates some of the diverse responses that can be expected in salmon populations responding to climate change, emphasizes the importance of life-history and phenological diversity as adaptive pathways for populations impacted by climate change, and argues for management that maximizes these forms of diversity.

Climate Change and Northern Fish Populations

Pages : 756
Book Description
These documents summarize some of the recent studies of the relationships among climate, the aquatic environment, and the dynamics of fish populations. The studies are mostly from the North Pacific ocean, but there are reports of investigations from the North Atlatic Ocean and from fresh water. Various papers include numerous examples of the relationships between fish abundance trends and the environment.
Thermal Adaptation

Book Description
Temperature profoundly impacts both the phenotypes and distributions of organisms. These thermal effects exert strong selective pressures on behaviour, physiology and life history when environmental temperatures vary over space and time. Despite temperature's significance, progress toward a quantitative theory of thermal adaptation has lagged behind empirical descriptions of patterns and processes. In this book, the author draws on theory from the more general discipline of evolutionary ecology to establish a framework for interpreting empirical studies of thermal biology. This novel synthesis of theoretical and empirical work generates new insights about the process of thermal adaptation and points the way towards a more general theory. The threat of rapid climatic change on a global scale provides a stark reminder of the challenges that remain for thermal biologists and adds a sense of urgency to this book's mission. Thermal Adaptation will benefit anyone who seeks to understand the relationship between environmental variation and phenotypic evolution. The book focuses on quantitative evolutionary models at the individual, population and community levels, and successfully integrates this theory with modern empirical approaches. By providing a synthetic overview of evolutionary thermal biology, this accessible text will appeal to both graduate students and established researchers in the fields of comparative, ecological, and evolutionary physiology. It will also interest the broader audience of professional ecologists and evolutionary biologists who require a comprehensive review of this topic, as well as those researchers working on the applied problems of regional and global climate change.
