Book Description
"Cultus Lake, British Columbia contains habitat that species at risk depend on for survival, yet is currently experiencing cultural eutrophication and climate-induced warming. In this study, assessments of lake water quality near the sediment-water interface, found hypoxic to near-anoxic conditions during the late-stratified period (i.e. late-summer to fall)"--Abstract, page vii.

Book Description
This paper makes recommendation for the identification of critical habitat for the SARA listed, Coastrange Sculpin (Cultus Population), based on best available information. Coastrange Sculpin (Cultus Population), Cottus aleuticus, informally recognized as Cultus Pygmy Sculpin, is a neotenic form of the Coastrange Sculpin and found only in Cultus Lake in the southwestern corner of British Columbia, Canada. The recommendation of critical habitat satisfies the species recovery goal - 2to ensure the long-term viability of the population in the wild. 3 Spatial extent, features and attributes of critical habitat are also recommended. Information with regards to the species, such as life history, biology, abundance, and threats are also reviewed and updated as appropriate.

Book Description
"The Cultus Pygmy Sculpin was assessed as Threatened by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) in 2000, and subsequently listed under the Species at Risk Act as such in June of 2003. In October of 2007 the final Recovery Strategy for Cultus Pygmy Sculpin (Cottus sp.) in Canada was posted to the Species at Risk Public Registry. An updated COSEWIC assessment in 2010 reconfirmed the species' status as Threatened (COSEWIC 2010). The recovery goal for Cultus Pygmy Sculpin is to ensure the long-term viability of the population in the wild. This report documents the progress of Recovery Strategy implementation for the Cultus Pygmy Sculpin. It summarizes progress that Fisheries and Oceans Canada, the Province of British Columbia's Ministry of Environment, and other interested parties have made towards achieving the goal and objectives set out in the Recovery Strategy, including: conducting new research and monitoring activities (including advancing studies to support the identification of critical habitat); and, completing management activities that help Canadians reduce impacts on, and better understand threats to, the Cultus Pygmy Sculpin"--Executive summary.

Book Description
Every year, countless juvenile Pacific salmon leave streams and rivers on their migration to feeding grounds in the North Pacific Ocean and the Bering Sea. After periods ranging from a few months to several years, adult salmon enter rivers along the coasts of Asia and North America to spawn and complete their life cycle. Within this general outline, various life history patterns, both among and within species, involve diverse ways of exploiting freshwater, estuarine, and marine habitats. There are seven species of Pacific salmon. Five (coho, chinook chum, pink, and sockeye) occur in both North America and Asia. Their complex life histories and spectacular migrations have long fascinated biologists and amateurs alike. Physiological Ecology of Pacific Salmon provides comprehensive reviews by leading researchers of the physiological adaptations that allow Pacific Salmon to sustain themselves in the diverse environments in which they live. It begins with an analysis of energy expenditure and continues with reviews of locomotion, growth, feeding, and nutrition. Subsequent chapters deal with osmotic adjustments enabling the passage between fresh and salt water, nitrogen excretion and regulation of acid-base balance, circulation and gas transfer, and finally, responses to stress. This thorough and authoritative volume will be a valuable reference for students and researchers of biology and fisheries science as they seek to understand the environmental requirements for the perpetuation of these unique and valuable species.

Book Description
This superbly researched, groundbreaking historical atlas presents a history of the civilization and territory of the Stó:lo, a First Nations people. Through words, archival photographs, and 86 full-color maps, the book details the mythic beginnings of the Stó:lo people and how white settlement turned their homeland into the bustling metropolis of Vancouver. An important document packed with fascinating information, the atlas also makes a significant contribution to cross-cultural understanding.
