Comparative Physiology of Fasting, Starvation, and Food Limitation by Marshall D. McCue Pdf

All animals face the possibility of food limitation and ultimately starvation-induced mortality. This book summarizes state of the art of starvation biology from the ecological causes of food limitation to the physiological and evolutionary consequences of prolonged fasting. It is written for an audience with an understanding of general principles in animal physiology, yet offers a level of analysis and interpretation that will engage seasoned scientists. Each chapter is written by active researchers in the field of comparative physiology and draws on the primary literature of starvation both in nature and the laboratory. The chapters are organized among broad taxonomic categories, such as protists, arthropods, fishes, reptiles, birds, and flying, aquatic, and terrestrial mammals including humans; particularly well-studied animal models, e.g. endotherms are further organized by experimental approaches, such as analyses of blood metabolites, stable isotopes, thermobiology, and modeling of body composition.

Intermittent fasting in chickens by Caroline Lindholm Pdf

Broiler breeder chickens are the parent stock used to produce broiler chickens raised for human consumption and have long been caught in a welfare dilemma. The immensely successful selection of fast-growing meat-type chickens over the last 80 years has created a remarkably efficient meat-producer and given us access to cheap chicken meat but has also created health problems for the animals. These problems especially affect the breeder generation, which must be raised with strict feed restriction to limit weight gain and thus maintain physical health and normal fertility. At the same time, however, feed restriction causes chronic hunger and feeding frustration with reduced animal welfare as a result. In the EU alone 60 million breeders are affected annually and although the problem is well-known within the industry, there is financial incentive to keep selecting for even higher growth potential in broilers, further increasing the problems for broiler breeders. Many strategies for reducing the impact of growth restriction on breeder welfare have been suggested and are usually aimed at somehow increasing the amount of feed given at feeding times. This can be done either through adding bulky fibers to the diet or by reducing feeding frequency. In this thesis, focus is on the latter as we explore the effects of intermittent fasting (IF) on the welfare of young broiler breeders as well as wild-type Red Junglefowl. Intermittent fasting, or “skip-a-day” feeding, is supposedly the most common feeding strategy for broiler breeders worldwide but is perceived as welfare-reducing and thus illegal in Sweden and several other European countries. In spite of this, the scientific knowledge of how this type of feeding affects chicken welfare is scarce. Assessing the overall effect of IF on breeder welfare is complicated by large variations in both physiological and behavioral parameters between feeding and fasting days, but it does appear that chicken welfare is improved at least on the feeding days of IF regimens. It also seems that some of the health benefits reported from mammalian studies of IF may apply to chickens as well, although behavioral indicators still point to welfare issues unless the level of feed restriction can be relaxed. In comparison with daily feed restriction, IF appears to increase the motivation for feed consumption but to reduce the motivation for appetitive behaviors such as foraging, which may explain why birds fed on this type of schedule are often reported as calmer.

Physiology of Marine Mammals by Michael Castellini,Jo-Ann Mellish Pdf

Suppose you were designing a marine mammal. What would they need to live in the ocean? How would you keep them warm? What design features would allow them to dive for very long periods to extreme depths? Do they need water to drink? How would they minimize the cost of swimming, and how would they find their prey in the deep and dark? These questions and more are examined in detail throughout Marine Mammal Physiology, which explores how marine mammals live in the sea from a physiological point of view. This undergraduate textbook considers the essential aspects of what makes a marine mammal different from terrestrial mammals, beyond just their environment. It focuses on the physiological and biochemical traits that have allowed this group of mammals to effectively exploit the marine environment that is so hostile to humans. The content of this book is organised around common student questions, taking the undergraduate's point of view as the starting point. Each chapter provides a set of PowerPoint slides for instructors to use in teaching and students to use as study guides. New "Study Questions" and "Critical Thinking Points" conclude each chapter, which are each motivated by a "Driving Question" such as "How do mammals stay warm in a cold ocean?" or "How do mammals survive the crushing pressures of the deep sea?" Full-colour images and comprehensive, accessible content make this the definitive textbook for marine mammal physiology.

Why Fast? by Christine Baumgarthuber Pdf

A sober engagement with the diverse meanings of intermittent fasting in human culture. Fasting from food is a controversial, dangerous, and yet utterly normal human practice. In Why Fast?, Christine Baumgarthuber engages our fascination with restrictive eating in cultural history. If fasting offers few health benefits, why do people fast? Why have we always fasted? Does fasting speak to something deep and immutable within us? Why are our bodies so well adapted to intermittent fasting? And, what might this ancient, ascetic ritual offer us today? Thoughtful and considered, Why Fast? is a sober reconsideration of a contentious practice.

The Design of Mammals by John William Prothero Pdf

Despite an astonishing 100 million-fold range in adult body mass from bumblebee bat to blue whale, all mammals are formed of the same kinds of molecules, cells, tissues and organs and to the same overall body plan. A scaling approach investigates the principles of mammal design by examining the ways in which mammals of diverse size and taxonomy are quantitatively comparable. This book presents an extensive reanalysis of scaling data collected over a quarter of a century, including many rarely or never-cited sources. The result is an unparalleled contribution to understanding scaling in mammals, addressing a uniquely extensive range of mammal attributes and using substantially larger and more rigorously screened samples than in any prior works. An invaluable resource for all those interested in the 'design' of mammals, this is an ideal resource for postgraduates and researchers in a range of fields from comparative physiology to ecology.

Handbook of Famine, Starvation, and Nutrient Deprivation by Victor R. Preedy,Vinood B. Patel Pdf

This book addresses the causes and effects of nutrient deficiencies along the cell-to-communities continuum. The book is primarily concerned with a lack or deficiency of one or more micro- or macronutrients in connection with malnutrition, under nutrition, and starvation. Embedded within the deficiency states is acute restriction whereby food is withdrawn completely for short periods, as when individuals are adhering to religious requirements or undergoing surgical procedures. Further downstream is the consumption of a fraction of the normal diet, as when individuals are dieting or when there is restriction in the amount or variety of food available. The causes of such reductions in dietary intake are varied and also include the social context of poverty, financial limitations, and famine. Refugees and displaced persons may also be vulnerable to under nutrition or total starvation. Diseases may also impact on the total food consumed, such as when there are physical impediments (intestinal obstruction or dysphagia) or anorexia (induced by organic disease or as a disease process per se, ie, anorexia nervosa). This book, organized as approximately 125 chapters in 17 major sections, covers the variable manifestations of dietary restrictions on cells, whole organs, the individual, and societies.

Marine Mammal Physiology by Michael A. Castellini,Jo-Ann Mellish Pdf

Suppose you were designing a marine mammal. What would you need to think about to allow it to live in the ocean? How would you keep it warm? What would you design to allow it to dive for very long periods to extreme depths? Where would it find water to drink? How would you minimize the cost of swimming, and how would it find its prey in the deep and dark? These questions and more are examined in detail throughout this book. Marine Mammal Physiology: Requisites for Ocean Living is the first textbook focused on how marine mammals live in the sea from a physiological point of view. It explores the essential aspects of what makes a marine mammal different from terrestrial mammals, beyond just their environment. Unlike many publications and books that cover these species from almost all perspectives, this textbook takes a step back to focus on the physiological and biochemical characteristics that have allowed these mammals as a group to exploit effectively the marine environment that is so hostile to humans. The chapter topics are grouped into major themes: diving and locomotion, nutrition and energetics, reproduction, sensory systems, and environmental interactions. Each chapter is arranged around a common perspective and theme: the big picture challenge and summary and what is known specifically by order. To aid you even further, the authors include a "Toolbox" section in each chapter where they discuss the newest methods for understanding and working on the physiology of marine mammals.

Islands and Snakes by Marcio Martins Pdf

In this follow-up to Islands and Snakes, this book contains 15 chapters describing diversity and conservation of snakes on islands, with foci on selected island systems not previously summarized. Attendant topics include biogeography, plasticity and evolutionary responses to insular conditions, invasive species, importance and collapse of trophic systems, threats to insular snake populations, and strategies of conservation to save them. Chapters include descriptions of snake faunas on larger islands such as Borneo and New Guinea; reproductive biology of insular snakes; phenotypic evolution; physiology and growth patterns related to diet and environment; patterns of endemism; taxonomy of snake radiations; and history of invasions by snakes on islands. The final chapter presents a discussion of prospects and overview of conservation of snakes on islands. Chapters are contributed by international authorities on respective island-and-snake systems. The latter include some islands or archipelagos that are young, or of high importance, or support snake populations that were previously not well known. The content includes colourful photographs, informative illustrations, and in some cases synthesis of new data relevant to the importance of islands for understanding the ecological underpinnings and genesis of biodiversity. Each chapter is appropriately referenced with citations to scientific literature, and where useful, footnotes, tables and graphic information supporting the narrative of the respective subject matter. The overall presentation is intended to provide readers with an enhanced appreciation for islands and the spectacular snakes that might live there.
