Available in PDF, EPUB and Kindle. Book excerpt: "Brook trout movement-related life history strategies vary considerably and range from individuals that stay within the same 100 meters their entire life to individuals that are potamodromous or anadromous. Potential drivers of movement life histories have been the subject of much research in fish, with genetic subpopulation explanations often failing to explain the phenomenon. Metabolic phenotypes have been suggested as a possible driver for expression of different movement life histories. I investigated if metabolic phenotypes are related to movement strategies within a population of brook trout (Salvelinus fontinalis) in Unnamed Creek, a tributary to the Rock River, Alger County, MI. Intermittent flow respirometry was used in the field using ambient stream water to determine metabolic phenotypes of wild trout. Individuals were then tagged with passive integrated transponders (PIT) and tracked with stationary readers and a backpack reader during the summer. Brook trout that moved over 250m displayed a significantly larger aerobic scope than individuals that moved less than 250m. Temperature effects on metabolic measures were not detected among the brook trout in this study, but this could be due to wild acclimation to a range of temperatures rather than a single value.. This study suggests that brook trout metabolic phenotypes are variable between individuals and likely relate to movement phenotype under natural field conditions."--Abstract.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: I tested the hypothesis that consistent individual differences (CIDs) in behaviour arise from CIDs in metabolic performance using offspring from polymorphic Brook Trout (Salvelinus fontinalis) from Lake Superior and its tributaries. Large, fast-growing migrants move between tributaries and the lake. Small, slow-growing residents remain in the tributaries. Four measures of behaviour: risk-taking, general activity, association with a conspecific, and propensity to disperse; as well as three measures metabolic performance: standard and maximum metabolic rate, and aerobic scope, was quantified for 60 individuals (age 2+) from migrant-migrant and migrant-resident families. Three of four behavioural measures and all of the metabolic measures were repeatable. CIDs in behaviour were not related to CIDs in metabolic performance. Further, the nature of correlations between behaviour and metabolic performance did not differ between migrant-migrant and migrant-resident offspring. The mechanisms underlying relationships between CIDs in behaviour and metabolism are likely more complex than hypothesized in current models.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: I investigated the relationship between personality and migration in Lake Superior Brook Trout (Salvelinus fontinalis) known to display migratory polymorphisms: a small bodied stream resident, and a larger bodied migrant. Resident and migrant Brook Trout were captured and crossed to create 26 families. Five personality metrics were quantified for offspring and tested for (i) repeatability and heritability, (ii) phenotypic and genetic correlations, and (iii) relationships with the migratory behaviour of their parents. Assays of risk-taking, general activity, social behaviour, and propensity to disperse were conducted for the 0+, 1+, and 2+ age classes. Personality metrics were repeatable and heritable across age classes. I found evidence for a behaviour syndrome involving risk-taking, activity, and propensity to disperse. However, the personality of the offspring was not related to the migratory status of their parents at any age, suggesting that personality and migratory behaviour are not controlled by a simple, proximate mechanism.

Download or read book Ecology behaviour and conservation of the charrs genus Salvelinus written by Pierre Magnan and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salvelinus species are one of the most thoroughly studied groups of fishes. Many reasons explain this intense interest in charr biology. Charrs have a Holarctic distribution encompassing many Asian, North American, and European countries and occupy diverse marine and freshwater environments. Furthermore, the current distribution of charr includes areas that were directly influenced by climate and topographic change associated with the many Pleistocene glaciations. Undoubtedly, these conditions have promoted much of the tremendous morphological, ecological, and genetic variability and plasticity within Salvelinus species and they make charr very good models to study evolutionary processes 'in action'. Many charr species also exhibit demographic characteristics such as slow growth, late maturity, and life in extreme environments, that may increase their susceptibility to extinction from habitat changes and overexploitation, especially in depauperate aquatic habitats. This vulnerability makes understanding their biology of great relevance to biodiversity and conservation. Finally, charr are of great cultural, commercial, and recreational significance to many communities, and their intimate linkage with human societies has stimulated much interest in this enigmatic genus. This volume comprises a selection of papers presented at the fourth International Charr Symposium held in Trois-Rivières (Québec, Canada), from 26 June to 1 July 2000. It includes 31 papers on ecological interactions and behaviour, trophic polymorphism, movement and migration, ecophysiology and evolutionary genetics, ecological parasitology, environmental stress and conservation. These studies cannot cover all recent developments in the ecology, behaviour and conservation of Salvelinus species, but collecting them into a special volume should bring attention to current research on this important genus and stimulate further work on Salvelinus species.

Download or read book Fish Energetics written by Peter Tytler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.

Download or read book Physiological Adaptations to Swimming in Fish written by Josep V. Planas and published by Frontiers Media SA. This book was released on 2017-08-16 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Swimming is an integral part of the life history of many fish species as is intimately linked with their ability to express feeding and predator avoidance behaviors, habitat selection and environmental preferences, social and reproductive behaviors as well as migratory behaviors. Therefore, swimming is an important determinant factor of fitness in a true Darwinian sense and, not surprisingly, swimming performance has been often used as a measure of physiological fitness in fish. The main aim of this Research Topic is to showcase some of the current studies designed to improve our understanding of the physiological energetic and metabolic requirements of swimming and of the adaptive responses to swimming in fish.

Download or read book Ecology of Atlantic Salmon and Brown Trout written by Bror Jonsson and published by Springer Science & Business Media. This book was released on 2011-05-03 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Destruction of habitat is the major cause for loss of biodiversity including variation in life history and habitat ecology. Each species and population adapts to its environment, adaptations visible in morphology, ecology, behaviour, physiology and genetics. Here, the authors present the population ecology of Atlantic salmon and brown trout and how it is influenced by the environment in terms of growth, migration, spawning and recruitment. Salmonids appeared as freshwater fish some 50 million years ago. Atlantic salmon and brown trout evolved in the Atlantic basin, Atlantic salmon in North America and Europe, brown trout in Europe, Northern Africa and Western Asia. The species live in small streams as well as large rivers, lakes, estuaries, coastal seas and oceans, with brown trout better adapted to small streams and less well adapted to feeding in the ocean than Atlantic salmon. Smolt and adult sizes and longevity are constrained by habitat conditions of populations spawning in small streams. Feeding, wintering and spawning opportunities influence migratory versus resident lifestyles, while the growth rate influences egg size and number, age at maturity, reproductive success and longevity. Further, early experiences influence later performance. For instance, juvenile behaviour influences adult homing, competition for spawning habitat, partner finding and predator avoidance. The abundance of wild Atlantic salmon populations has declined in recent years; climate change and escaped farmed salmon are major threats. The climate influences through changes in temperature and flow, while escaped farmed salmon do so through ecological competition, interbreeding and the spreading of contagious diseases. The authors pinpoint essential problems and offer suggestions as to how they can be reduced. In this context, population enhancement, habitat restoration and management are also discussed. The text closes with a presentation of what the authors view as major scientific challenges in ecological research on these species.

Available in PDF, EPUB and Kindle. Book excerpt: Integrative Organismal Biology synthesizes current understandings of the causes and consequences of individual variation at the physiological, behavioral and organismal levels. Emphasizing key topics such as phenotypic plasticity and flexibility, and summarizing emerging areas such as ecological immunology, oxidative stress biology and others, Integrative Organismal Biology pulls together information from diverse disciplines to provide a synthetic view of the role of the individual in evolution. Beginning with the role of the individual in evolutionary and ecological processes, the book covers theory and mechanism from both classic and modern perspectives. Chapters explore concepts such as phenotypic plasticity, genetic and epigenetic variation, physiological and phenotypic variation, homeostasis, and gene and physiological regulatory networks. A concluding section interweaves these concepts through a series of case studies of life processes such as aging, reproduction, and immune defense. Written and edited by leaders in the field, Integrative Organismal Biology will be an important advanced textbook for students and researchers across a variety of subdisciplines of integrative biology.
