This book was released on 2014-03 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Juvenile Chinook salmon (Oncorhynchus tshawytscha) emigrating from natal tributaries of the Sacramento River may use a number of migration routes to negotiate the Sacramento-San Joaquin River Delta (hereafter, "the Delta"), each of which may influence their probability of surviving. We applied a mark-recapture model to data from acoustically tagged juvenile late-fall Chinook salmon that migrated through the Delta during the winter of 2009-10 (hereafter, 2010). This report presents findings from our fourth year of research.

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.
Download or read book Suisun Marsh written by Peter B. Moyle and published by Univ of California Press. This book was released on 2014-03-26 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of California's most remarkable wetlands, Suisun Marsh is the largest tidal marsh on the West Coast and a major feature of the San Francisco Estuary. This productive and unique habitat supports endemic species, is a nursery for native fishes, and is a vital link for migratory waterfowl. The 6,000-year-old marsh has been affected by human activity, and humans will continue to have significant impacts on the marsh as the sea level rises and cultural values shift in the century ahead. This study includes in-depth information about the ecological and human history of Suisun Marsh, its abiotic and biotic characteristics, agents of ecological change, and alternative futures facing this ecosystem.

Download or read book Decision Making in Natural Resource Management written by Michael J. Conroy and published by John Wiley & Sons. This book was released on 2013-03-18 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended for use by natural resource managers and scientists, and students in the fields of natural resource management, ecology, and conservation biology, who are confronted with complex and difficult decision making problems. The book takes readers through the process of developing a structured approach to decision making, by firstly deconstructing decisions into component parts, which are each fully analyzed and then reassembled to form a working decision model. The book integrates common-sense ideas about problem definitions, such as the need for decisions to be driven by explicit objectives, with sophisticated approaches for modeling decision influence and incorporating feedback from monitoring programs into decision making via adaptive management. Numerous worked examples are provided for illustration, along with detailed case studies illustrating the authors’ experience in applying structured approaches. There is also a series of detailed technical appendices. An accompanying website provides computer code and data used in the worked examples.
