Available in PDF, EPUB and Kindle. Book excerpt: "Building upon the rapidly-growing body of literature documenting how natural systems are responding to, and are at risk from, human-induced climate change, this book provides case-study examples of how a diverse range of species and ecological systems in California are changing with the climate. These case studies originate from multiple ecological fields (genetics, population biology, habitat studies, community ecology, landscape ecology, paleobiology) and are framed by chapters describing approaches and tools for climate-adaptation planning, reviewing climate impacts and biological responses, and encouraging the use of historical data. This framing emphasizes the need for partnerships between researchers and resource managers in addressing climate-related challenges, and highlights how communication strengthens these partnerships with 'conversations' between chapter authors and managers. Such connections help move advances in science from research reports to 'on the ground' changes that help protect species, and support all life"--Provided by publisher.

Download or read book Scientific Evaluation of Biological Opinions on Endangered and Threatened Fishes in the Klamath River Basin written by National Research Council and published by National Academies Press. This book was released on 2002-08-22 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: During 2001, a severe drought occurred in the Klamath River Basin. The U.S. Department of the Interior (DOI) determined that the newly issued biological opinions and their RPAs must prevail; thus, water that would have gone to irrigators was directed almost entirely to attempts to maintain minimum lake levels and minimum flows as prescribed in the two RPAs. The severe economic consequences of this change in water management led DOI to request that the National Research Council (NRC) independently review the scientific and technical validity of the government's biological opinions and their RPAs. The NRC Committee on Endangered and Threatened Fishes in the Klamath River Basin was formed in response to this request. The committee was charged with filing an interim report after approximately less than 3 months of study and a final report after about 18 months of study. The interim report, which is summarized here, focuses on the biological assessments of the USBR (2001) and the USFWS and NMFS biological opinions of 2001 regarding the effects of Klamath Project operations on the three listed fish species.

This book was released on 2004-04-30 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1988 the U.S. Fish and Wildlife Service listed two endemic fishes of the upper Klamath River basin of Oregon and California, the sucker and the Lost River sucker, as endangered under the federal Endangered Species Act (ESA). In 1997, the National Marine Fisheries Service added the Southern Oregon Northern coastal California (SONCC) coho salmon as a threatened species to the list. The leading factors attributed to the decline of these species were overfishing, blockage of migration, entrainment by water management structures, habitat degradation, nonnative species, and poor water quality. Endangered and Threatened Fishes of the Klamath River Basin addresses the scientific aspects related to the continued survival of coho salmon and shortnose and Lost River suckers in the Klamath River. The book further examines and identifies gaps in the knowledge and scientific information needed for recovery of the listed species and proves an assessment of scientific considerations relevant to strategies for promoting the recovery of those species.

Download or read book The Behavior and Ecology of Pacific Salmon and Trout written by Thomas P. Quinn and published by University of Washington Press. This book was released on 2018-10-01 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Behavior and Ecology of Pacific Salmon and Trout combines in-depth scientific information with outstanding photographs and original artwork to fully describe the fish species critical to the Pacific Rim. This completely revised and updated edition covers all aspects of the life cycle of these remarkable fish in the Pacific: homing migration from the open ocean through coastal waters and up rivers to their breeding grounds; courtship and reproduction; the lives of juvenile salmon and trout in rivers and lakes; migration to the sea; the structure of fish populations; and the importance of fish carcasses to the ecosystem. The book also includes information on salmon and trout transplanted outside their ranges. Fisheries expert Thomas P. Quinn writes with clarity and enthusiasm to interest a wide range of readers, including biologists, anglers, and naturalists. He provides the most current science available as well as perspectives on the past, present, and future of Pacific salmon and trout. In this edition: Over 100 beautiful color photographs of salmon and trout Updated information on all aspects of the salmon and trout life cycle Expanded coverage of trout

Book excerpt: Age analysis for 22 years (1980 excluded) showed that the overall percentages for female spawners was 53% (4-year olds), 38% (3-year olds), and 9% (5-year olds). The age composition of male spawners showed a high degree of variability throughout the study. Male chinook of age 2, 3 and 4 were dominant annually, but 5- and 6- year old fish were present in most spawning seasons. All chinook carcasses from which scales were collected were also measured for length (over 120 samples in 22 years). Decreases in mean length were documented for all age classes for each of the El Nino episodes that occurred during the study (1982-1984; 1992-1993; 1997-1998). The decreases in mean length appeared to carry forward for each cohort's age class. The total number of chinook redds was tabulated by counting "fresh" redds during weekly spawning surveys. The mean number of redds was 117 for the 23-year period with a mean of 0.9 redds per adult salmon or 1.8 redds per female.
