Book Description
For centuries, biologists have marvelled at how anadromous salmonids – fish that pass from rivers into oceans and back again – survive as they migrate between these two very different environments. Yet, relatively little is understood about what happens to salmonid species (including salmon, steelhead, char, and trout) in the estuaries where they make this transition from fresh to salt water. This book explains the critical role estuaries play in salmonid survival. Ecology of Salmonids in Estuaries around the World synthesizes information from a vast array of literature, to describe the specific adaptation of eighteen anadromous salmonids in four genera (Hucho, Oncorhynchus, Salmo, and Salvelinus) explain the ecological relationships between anadromous salmonids, the fish they coexist with, and their estuarine habitat discuss key fitness elements salmonids need for survival (including those relating to osmoregulation, growth and feeding mechanisms, and biotic interactions) provide guidance on how to conduct estuarine sampling and scientific aspects of management and recovery plans offer directions for future research. The critical reference is further enhanced by extensive supplementary appendices that are available online, including data tables, additional references on estuarine salmonids, and a primer on estuaries and salmonids for citizen scientists.

Book Description
Coastal Wetlands, Second Edition: An Integrated and Ecosystem Approach provides an understanding of the functioning of coastal ecosystems and the ecological services that they provide. As coastal wetlands are under a great deal of pressure from the dual forces of rising sea levels and the intervention of human populations, both along the estuary and in the river catchment, this book covers important issues, such as the destruction or degradation of wetlands from land reclamation and infrastructures, impacts from the discharge of pollutants, changes in river flows and sediment supplies, land clearing, and dam operations. - Covers climate change and its influence on coastal wetland form and function - Provides a fully updated and expanded resource, including new chapters on modeling, management and the impact of climate change - Contains full-color figures of wetlands and estuaries in different parts of the world

Book Description
Fish were once so abundant in BC waters that Indigenous elders recall dried salmon being stacked like firewood behind the stove. But declines on the BC coast have accelerated over the last century, with marine wildlife cut in half in just four decades. Protecting the Coast and Ocean explores how we can reverse such precipitous declines. This meticulous work catalogues not only Canadian laws and designations – marine protected areas, Indigenous protected and conserved areas, land-use measures, and zoning bylaws – but also international treaties that shape marine conservation and support collaboration. The authors analyze and compare legal tools, rating their strengths and weaknesses. In-depth case studies illustrate how each instrument has been used in practice. Despite the impact of climate change, overfishing, and pollution, Protecting the Coast and Ocean convincingly demonstrates that legal tools are available to reverse species extinction and plan for a resilient ocean.

Book Description
The 16 papers in this volume constitute a summary of recent research on the geological architecture and environment of the Fraser River delta, and the physical and chemical processes operating on it. The first two papers are overviews of the geological and seismic setting of the delta. The next two papers summarize present-day sedimentary environments on the delta. A third group of papers covers the geological architecture, or lithostratigraphy, of the delta and the biological structure or biofacies of the delta. The final group of papers is concerned with natural hazards and environmental issues, including earthquakes, geotechnical stability, and seafloor sediment geochemistry.
