Available in PDF, EPUB and Kindle. Book excerpt: Bioenergetics is the study of balance between energy supply and energy expenditure and requires an examination of physiological processes through which energy is transformed in living organisms. Studies on the flow and allocation of energy in biological systems often have, as their ultimate goal, the construction of a budget describing the partitioning of energy within an individual or population. Such budgets are then used to make inference about physiology or ecology in particular explaining why an organism or population does what it is observed to do assuming that energy allocation is the overriding concern. Bioenergetic modelling is an alternative method for estimating feeding rates in a natural population. These models quantify the relationship between feeding rates and growth relative to temperature, body size and activity. Bioenergetic models have been applied to address ecological questions in a wide variety of taxa.

Download or read book The Biology of Decapod Crustacean Larvae written by Klaus Anger and published by CRC Press. This book was released on 2001-06-01 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: About 90 per cent of the 10,000 known species of the Crustacea Decapoda live in oceans and adjacent coastal and estuarine regions, and most of them pass through a complex life history comprising a benthic (juvenile-adult) and a planktonic (larval) phase. The larvae show a wide array of adaptations to the pelagic environment, including modifications in their functional morphology, anatomy, the molting cycle, nutrition, growth, chemical composition, metabolism, energy partitioning, ecology and behaviour.;All these traits are reviewed in this volume, attempting to promote an integrated, multidisciplinary view of the biology of larval Decapoda and other crustacean taxa. Emphasis is placed on the lesser-known anatomical, bioenergetic and ecophysiological aspects of larval life, as morphology has already been extensively documented. Changes in biological parameters (for example, rates of feeding, growth, metabolism) are shown in successive developmental stages, within individual stages, and as responses to environmental factors. Particular attention is paid to interrelationships between intrinsic phenomena (molting cycle, organogenesis, growth) and the overlaying effects of extrinsic factors (for example, food, temperature, salinity, pollution). Concluding from the available data, major bias and gaps in present knowledge of larval biology are identified and discussed as to their potential significance in future research.
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 Environmental Adaptations written by F. John Vernberg and published by Elsevier. This book was released on 2014-04-24 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Adaptations examines the dynamic interaction between an organism and its external environment in order to emphasize the adaptive significance of its responses. Focusing on the adaptations of crustaceans, it bridges the gap between other volumes in the series which deal in detail with the functional machinery of crustaceans and those dealing with ecological, taxonomic, behavioral, and applied subjects. This book is divided into seven chapters. The first two chapters highlight the range of respiratory responses exhibited by crustaceans when subjected to various environmental factors. Chapter 3 summarizes the mechanisms by which crustaceans take up energy and food from the environment under fluctuating conditions. It also reviews the assimilation efficiencies of crustaceans and the predator-prey interaction. Chapter 4 deals with ionic and osmoregulation from the view of its interaction with the environment. It emphasizes the adaptive nature of chemical regulation that enables various crustaceans to inhabit waters ranging from hypersaline ponds to fresh water. Chapter 5 discusses how the various species are reproductively adapted to generate offspring in the tremendous diversity of habitats occupied by crustaceans. The last two chapters report on the specific adaptations of crustaceans to terrestrial and freshwater habitats. This book is a valuable source for zoologists, paleontologists, ecologists, physiologists, endocrinologists, morphologists, pathologists, and fisheries biologists, and an essential reference work for institutional libraries.

Download or read book Stressors in the Marine Environment written by Martin Solan and published by Oxford University Press. This book was released on 2016-03-10 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: A multitude of direct and indirect human influences have significantly altered the environmental conditions, composition, and diversity of marine communities. However, understanding and predicting the combined impacts of single and multiple stressors is particularly challenging because observed ecological feedbacks are underpinned by a number of physiological and behavioural responses that reflect stressor type, severity, and timing. Furthermore, integration between the traditional domains of physiology and ecology tends to be fragmented and focused towards the effects of a specific stressor or set of circumstances. This novel volume summarises the latest research in the physiological and ecological responses of marine species to a comprehensive range of marine stressors, including chemical and noise pollution, ocean acidification, hypoxia, UV radiation, thermal and salinity stress before providing a perspective on future outcomes for some of the most pressing environmental issues facing society today. Stressors in the Marine Environment synthesises the combined expertise of a range of international researchers, providing a truly interdisciplinary and accessible summary of the field. It is essential reading for graduate students as well as professional researchers in environmental physiology, ecology, marine biology, conservation biology, and marine resource management. It will also be of particular relevance and use to the regulatory agencies and authorities tasked with managing the marine environment, including social scientists and environmental economists.
