This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Territoriality is thought to play an important role in the population regulation of animals. Consequently, the factors that affect territory size will also affect the number of individuals that can settle in a particular habitat. The prior-resident-advantage hypothesis predicts that territories will be smaller and more numerous in areas where individuals arrive synchronously rather than asynchronously, due to the dominance of residents over newcomers. I tested this prediction in a laboratory study with juvenile rainbow trout (Oncorhynchus mykiss). Although there was some evidence that early arrivers were more aggressive than late arrivers, there was no strong evidence that settlement pattern has an effect on the number and size of territories. In juvenile salmonid fishes, individual growth rate typically decreases with increasing density in observational field studies and territory size typically decreases with density in experimental laboratory studies. The validity of these studies has been questioned, because cause and effect cannot be inferred from the field studies and experimental laboratory studies are often unrealistic. To address the shortcomings of both approaches, I performed a field-based experiment using juvenile Atlantic salmon (Salmo salar) at Catamaran Brook, New Brunswick. I manipulated the density of salmon in mesh enclosures, while measuring the growth rate and territory size of the salmon. As predicted, both growth rate and territory size decreased with increasing density, providing strong support for previous studies.

Available in PDF, EPUB and Kindle. Book excerpt: The Atlantic salmon is one of the most prized and exploited species worldwide, being at the centre of a massive sports fishing industry and increasingly as the major farmed species in many countries worldwide. Atlantic Salmon Ecology is a landmark publication, both scientifically important and visually attractive. Comprehensively covering all major aspects of the relationship of the Atlantic salmon with its environment, chapters include details of migration and dispersal, reproduction, habitat requirements, feeding, growth rates, competition, predation, parasitsm, population dynamics, effects of landscape use, hydro power development, climate change, and exploitation. The book closes with a summary and look at possible future research directions. Backed by the Norwegian Research Council and with editors and contributors widely known and respected, Atlantic Salmon Ecology is an essential purchase for all those working with this species, including fisheries scientists and managers, fish biologists, ecologists, physiologists, environmental biologists and aquatic scientists, fish and wildlife department personnel and regulatory bodies. Libraries in all universities and research establishments where these subjects are studied and taught should have copies of this important publication. Comprehensive and up-to-date coverage of Atlantic Salmon Atlantic Salmon is one of the world's most commercially important species Backed by the Norwegian Research Council Experienced editor and internationally respected contributors

Download or read book Trout and Salmon written by Trevor Crisp and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important book contains a great wealth of practical information on trout and salmon, species of fish that are of huge scientific and commercial interest. The introductory chapters of Trout and Salmon cover the biology and environmental variables of importance when considering these species. Further chapters encompass current information on the ecology of salmon and trout, with particular emphasis on the definition and quantification, where possible, of their environmental requirements and limitations. Comprehensive coverage of the impacts of human activities on trout and salmon is included, together with important aspects of relevance when considering issues of species conservation and habitat restoration. The book concentrates on the two species of the genus Salmo with many references and comparisons with the genus Oncorhynchus. Conclusions drawn within the book apply to both genera and as such the book will have relevance for both Europe and North America as well as other areas where these genera occur. Trevor Crisp has written a book that will be of great interest and use to fish biologists and fisheries scientists, to aquatic biologists, conservationists, ecologists and environmental scientists. The book will be particularly valuable for those working in government environment agencies and fish and wildlife departments and to all those involved in the management of these important species, their fisheries and habitats.

Download or read book Feeding Ecology of Fish written by Shelby D. Gerking and published by Elsevier. This book was released on 2014-04-25 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feeding Ecology of Fish establishes a comprehensive framework for the variable ecological patterns exemplified by feeding fishes. The author, a former president of the American Fisheries Society, devotes special attention to synthesizing empirical studies in categorizing feeding patterns. This book shows how remarkably adaptable fish can be with regard to selecting food, often from trophic levels not usually occupied. Relying on a thorough literature survey, Feeding Ecology of Fish will be an invaluable reference for both fishery scientists and ecological theorists. Organization by trophic level Emphasis on empirical studies Broad coverage of a diverse field

Available in PDF, EPUB and Kindle. Book excerpt: Reflecting a decade's worth of changes, Human Safety and Risk Management, Second Edition contains new chapters addressing safety culture and models of risk as well as an extensive re-working of the material from the earlier edition. Examining a wide range of approaches to risk, the authors define safety culture and review theoretical models that elucidate mechanisms linking safety culture with safety performance. Filled with practical examples and case studies and drawing on a range of disciplines, the book explores individual differences and the many ways in which human beings are alike within a risk and safety context. It delineates a risk management approach that includes a range of techniques such as risk assessment, safety audit, and safety interventions. The authors address concepts central to workplace safety such as attitudes and their link with behavior. They discuss managing behavior in work environments including key functions and benefits of groups, factors influencing team effectiveness, and barriers to effectiveness such as groupthink.
