Book excerpt: Historically, white sturgeon moved throughout the Columbia River system, ranging freely from the estuary to the headwaters, with the possible exception of limited passage at Cascades, Celilo and Kettle Falls during spring floods. Construction of Rock Island Dam in 1933, followed by Bonneville in 1938 and Grand Coulee in 1941, completely disrupted sturgeon migratory opportunity, and with the 17 successive Columbia and Snake river dams constructed over the next 32 years an entirely different river system was created for the species. Sturgeon caught between dams were essentially isolated populations with severely limited reproduction potential. Some reservoirs ran from dam to dam with no river habitat remaining, while other reaches had various lengths of free running river, but drastically reduced from historical situations. However, if reservoirs provide habitat for sturgeon use, and therefore compensate to some degree for river loss, the major limiting factors associated with population viability may be reduced spawning success, either from lack of suitable area or poor incubation environments. The most upstream impoundment of the Columbia River in the United States is Lake Roosevelt, behind Grand Coulee Dam. If sturgeon don't use Lake Roosevelt the capacity of the system to sustain a large sturgeon population would be understandably limited, and much reduced from the pre-dam era. In general this study found that sturgeon spawner aggregations from early spring to mid- summer depend most heavily on the timing of increasing water temperature. In the spring the water temperatures seem to stimulate the fish to start feeding and leave deep pools. The summer provides access to broader and shallower areas for food. The study on sturgeon movement was an attempt to define habitat use in such a reservoir/river system.

Available in PDF, EPUB and Kindle. Book excerpt: This book was written by undergraduate students at The Ohio State University (OSU) who were enrolled in the class Introduction to Environmental Science. The chapters describe some of Earth's major environmental challenges and discuss ways that humans are using cutting-edge science and engineering to provide sustainable solutions to these problems. Topics are as diverse as the students, who represent virtually every department, school and college at OSU. The environmental issue that is described in each chapter is particularly important to the author, who hopes that their story will serve as inspiration to protect Earth for all life.
Download or read book Climate Change and Indigenous Peoples in the United States written by Julie Koppel Maldonado and published by Springer. This book was released on 2014-04-05 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a long history and deep connection to the Earth’s resources, indigenous peoples have an intimate understanding and ability to observe the impacts linked to climate change. Traditional ecological knowledge and tribal experience play a key role in developing future scientific solutions for adaptation to the impacts. The book explores climate-related issues for indigenous communities in the United States, including loss of traditional knowledge, forests and ecosystems, food security and traditional foods, as well as water, Arctic sea ice loss, permafrost thaw and relocation. The book also highlights how tribal communities and programs are responding to the changing environments. Fifty authors from tribal communities, academia, government agencies and NGOs contributed to the book. Previously published in Climatic Change, Volume 120, Issue 3, 2013.
Download or read book Introductory Fisheries Analyses with R written by Derek H. Ogle and published by CRC Press. This book was released on 2016-01-05 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: A How-To Guide for Conducting Common Fisheries-Related Analyses in R Introductory Fisheries Analyses with R provides detailed instructions on performing basic fisheries stock assessment analyses in the R environment. Accessible to practicing fisheries scientists as well as advanced undergraduate and graduate students, the book demonstrates the flexibility and power of R, offers insight into the reproducibility of script-based analyses, and shows how the use of R leads to more efficient and productive work in fisheries science. The first three chapters present a minimal introduction to the R environment that builds a foundation for the fisheries-specific analyses in the remainder of the book. These chapters help you become familiar with R for basic fisheries analyses and graphics. Subsequent chapters focus on methods to analyze age comparisons, age-length keys, size structure, weight-length relationships, condition, abundance (from capture-recapture and depletion data), mortality rates, individual growth, and the stock-recruit relationship. The fundamental statistical methods of linear regression, analysis of variance (ANOVA), and nonlinear regression are demonstrated within the contexts of these common fisheries analyses. For each analysis, the author completely explains the R functions and provides sufficient background information so that you can confidently implement each method. Web Resource The author’s website at http://derekogle.com/IFAR/ includes the data files and R code for each chapter, enabling you to reproduce the results in the book as well as create your own scripts. The site also offers supplemental code for more advanced analyses and practice exercises for every chapter.

Available in PDF, EPUB and Kindle. Book excerpt: "In the early 1990s, a small group of "AIDS denialists," including a University of California professor named Peter Duesberg, argued against virtually the entire medical establishment's consensus that the human immunodeficiency virus (HIV) was the cause of Acquired Immune Deficiency Syndrome. Science thrives on such counterintuitive challenges, but there was no evidence for Duesberg's beliefs, which turned out to be baseless. Once researchers found HIV, doctors and public health officials were able to save countless lives through measures aimed at preventing its transmission"--
Download or read book Albion s Seed written by David Hackett Fischer and published by Oxford University Press. This book was released on 1991-03-14 with total page 981 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fascinating book is the first volume in a projected cultural history of the United States, from the earliest English settlements to our own time. It is a history of American folkways as they have changed through time, and it argues a thesis about the importance for the United States of having been British in its cultural origins. While most people in the United States today have no British ancestors, they have assimilated regional cultures which were created by British colonists, even while preserving ethnic identities at the same time. In this sense, nearly all Americans are "Albion's Seed," no matter what their ethnicity may be. The concluding section of this remarkable book explores the ways that regional cultures have continued to dominate national politics from 1789 to 1988, and still help to shape attitudes toward education, government, gender, and violence, on which differences between American regions are greater than between European nations.

Available in PDF, EPUB and Kindle. Book excerpt: This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.
