This book was released on 2019 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global climate change is altering patterns of temperature variation, with unpredictable consequences for species and ecosystems. The Metabolic Theory of Ecology (MTE) provides a powerful framework for predicting climate change impacts on ectotherm metabolic performance in a variable temperature environment. MTE postulates that physiological and ecological processes are limited by organism metabolic rates, which scale predictably with body mass and temperature. The purpose of this study was to determine if different metabolic proxies generate different estimates of key MTE model parameters for the aquatic frog Xenopus laevis, and whether these parameters depend on temperature or thermal acclimation status. I used a novel experimental setup to measure temperature dependence of four different proxies for whole-body metabolism (total O2 consumption, cutaneous O2 consumption, pulmonary O2 consumption, and breathing rate), following acclimation to one of three temperatures (8, 17, or 26°C). Different metabolic proxies generated different mass-scaling exponents and Eᴀ estimates, highlighting the importance of metabolic proxy selection when parameterizing MTE based models. Animals acclimated to 17°C had higher O2 consumption across all temperatures, but there were no acclimation effects on MTE parameters. Because total O2 consumption represents the best estimate for whole-body metabolism, the results of the current study suggest that X. laevis have a greater reduction in their mass-specific metabolic rates than a typical vertebrate, which Kleiber's Law predicts should have a mass scaling exponent of 0.75. All Eᴀ estimates fall within the reported range (0.1 - 1.0 eV; mean of ~0.65 across taxa).

Download or read book Escaping From Predators written by William E. Cooper, Jr and published by Cambridge University Press. This book was released on 2015-05-28 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: When a predator attacks, prey are faced with a series of 'if', 'when' and 'how' escape decisions – these critical questions are the foci of this book. Cooper and Blumstein bring together a balance of theory and empirical research to summarise over fifty years of scattered research and benchmark current thinking in the rapidly expanding literature on the behavioural ecology of escaping. The book consolidates current and new behaviour models with taxonomically divided empirical chapters that demonstrate the application of escape theory to different groups. The chapters integrate behaviour with physiology, genetics and evolution to lead the reader through the complex decisions faced by prey during a predator attack, examining how these decisions interact with life history and individual variation. The chapter on best practice field methodology and the ideas for future research presented throughout, ensure this volume is practical as well as informative.
Download or read book Nutrition in Sport written by Ronald J. Maughan and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 699 pages. Available in PDF, EPUB and Kindle. Book excerpt: As sports have become more competitive over recent years researchers and trainers have been searching for new and innovative ways of improving performance. Ironically, an area as mundane as what an athlete eats can have profound effects on fitness, health and ultimately, performance in competition. Sports have also gained widespread acceptance in the therapeutic management of athletes with disorders associated with nutritional status. In addition, exercise has been one of the tools used for studying the control of metabolism, creating a wealth of scientific information that needs to be placed in the context of sports medicine and science. Nutrition in Sport provides an exhaustive review of the biochemistry and physiology of eating. The text is divided into three sections and commences with a discussion of the essential elements of diet, including sections on carbohydrates, proteins, fats, vitamins and trace elements, and drugs associated with nutrition. It also discusses athletes requiring special consideration, including vegetarians and diabetics. The second section considers the practical aspects of sports nutrition and discusses weight control (essential for sports with weight categories and athletes with eating disorders), the travelling athlete (where travel either disrupts established feeding patterns or introduces new hazards), environmental aspects of nutrition (including altitude and heat), and the role of sports nutritional products.

Download or read book Vertebrate Ecophysiology written by Don Bradshaw and published by Cambridge University Press. This book was released on 2003-04-24 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecophysiology attempts to clarify the role and importance of physiological processes, such as digestion and respiration, in the ecological relations of species in their natural habitats. The basic principles and methods that are central to any ecophysiological study are outlined and discussed, including animal capture, blood collection, and the measurement of plasma components and hormone levels. Attention is paid to animal welfare and ethical considerations, and the question of stress and how to identify its presence in animals in their natural environment is approached through a series of case studies. Examples are given from a wide range of vertebrates living in deserts, cold climates and oceans, and recent findings on the physiological adaptations of Antarctic birds and mammals are a highlight of the book. This textbook will provide an introduction to the study of ecophysiology for advanced undergraduates and postgraduate students, as well as researchers in ecology, biodiversity and conservation.

This book was released on 2020-06-01 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phytoplankton blooms, micro-algal blooms, toxic algae, red tides, or harmful algae, are all terms for naturally occurring phenomena that have occurred throughout recorded history. About 300 hundred species of micro algae are reported at times to form mass occurrence, so called blooms. Nearly one fourth of these species are known to produce toxins. Even non-toxic algal blooms can have devastating impacts when they lead to kills of fish and invertebrates by generating anoxic conditions. Some algal species, although non-toxic to humans, can produce exudates that can cause damage to the delicate gill tissues of fish (raphidophytes Chattonella, Heterosigma, and dinoflagellates Karenia, Karlodinium) . Aquatic animals can suffer devastating mortalities, which could lead economical and food losses, and eventually became a food security problem. Of greatest concern to humans are algal species that produce potent neurotoxins that can find their way through shellfish and fish to human consumers where they evoke a variety of gastrointestinal and neurological illnesses (paralytic shellfish poisoning (PSP), amnesic shellfish poisoning (ASP), diarrhoeic shellfish poisoning (DSP), neurotoxic shellfish poisoning (NSP), azaspiracid shellfish poisoning (AZP) and ciguatera fish poisoning (CFP)). Worldwide, ciguatoxins are estimated to cause around 50 000 cases of ciguatera fish poisoning annually; neurological effects may last for weeks or even years and one percent of these cases are fatal . Climate change and costal water over enrichment create an enabling environment for harmful algal blooms, which seem to have become more frequent, more intense and more widespread in the past decades.
