Book Synopsis Population Homeostasis by : Christopher J. Paradise
Download or read book Population Homeostasis written by Christopher J. Paradise and published by Momentum Press. This book was released on 2016-04-27 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will synthesize the concepts of selection against individuals in response to environmental change to illustrate how selection against individuals results in homeostasis at the population level. For instance, selection against the light phenotype of the peppered moth during the early part of the industrial revolution led to an increase of the dark phenotype, which was better camouflaged against the soot that accumulated on tree bark as a result of burning coal. Populations are shown to be regulated by feedback mechanisms, several of which are discussed here. Populations are regulated by extrinsic factors, such as competition and predation, and that lead to changes in intrinsic factors, such as reproduction. Changes in population density often lead to initiation of feedback mechanisms, such as changes in birth or death rates. In a final example, pollutants are shown to be a factor that can disrupt homeostasis of populations. In particular, populations of top predators, such as raptors, have suffered due to biomagnification of toxins.

Book Synopsis Population Pressure and Cultural Adjustment by : Virginia Deane Abernethy
Download or read book Population Pressure and Cultural Adjustment written by Virginia Deane Abernethy and published by Routledge. This book was released on 2018-04-17 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrating research from anthropology, biology, and history, this provocative, brilliant book proposes a theory of demographic equilibrium. The author's hypothesis is that human beings, like many other species, are able to adjust their population numbers to the carrying capacity of the environment. Abernethy points out that in response to perception of scarcity or abundance of resources, culturally mediated values, beliefs and behavioral patterns are modified in ways that can either raise or lower rates of population growth. Abernethy in this way moves beyond the ideological debates that have sundered the field of policy and population. In real world time and space, cultural adjustments that balance population and resources are made over a long stretch in relatively stable or known environments. These adjustments also operate in processes that involve technological advances that appear to increase carrying capacity, and these usually act to support and underwrite population growth in any given area. In her new introduction to this first paperback edition, Abernethy shows how many of the cultural changes the book predicted in 1979 have come to pass. She details a complex of behaviors that favor single life-styles or small family size that have contributed to low fertility rates among native-born Americans while fertility rates among immigrants continue to climb. Population Pressure and Cultural Adjustment is not simply a theoretical slogan, but discusses a rich set of different cultural situations where this homeostatic process has been disrupted or aborted. Often, disruption occurs after the infusion of foreign value systems as well as new forms of technological innovation, or when highly permeable social boundaries result in the importation of resources for which the limits and consequences are not fully appreciated by the host population. This work will inevitably be controversial because of its implications for the limits as well as the potential of public policy in both advanced and underdeveloped societies.
Book Synopsis The Circadian Clock by : Urs Albrecht
Download or read book The Circadian Clock written by Urs Albrecht and published by Springer Science & Business Media. This book was released on 2010-01-23 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the invitation to edit this volume, I wanted to take the opportunity to assemble reviews on different aspects of circadian clocks and rhythms. Although most c- tributions in this volume focus on mammalian circadian clocks, the historical int- duction and comparative clocks section illustrate the importance of various other organisms in deciphering the mechanisms and principles of circadian biology. Circadian rhythms have been studied for centuries, but only recently, a mole- lar understanding of this process has emerged. This has taken research on circadian clocks from mystic phenomenology to a mechanistic level; chains of molecular events can describe phenomena with remarkable accuracy. Nevertheless, current models of the functioning of circadian clocks are still rudimentary. This is not due to the faultiness of discovered mechanisms, but due to the lack of undiscovered processes involved in contributing to circadian rhythmicity. We know for example, that the general circadian mechanism is not regulated equally in all tissues of m- mals. Hence, a lot still needs to be discovered to get a full understanding of cir- dian rhythms at the systems level. In this respect, technology has advanced at high speed in the last years and provided us with data illustrating the sheer complexity of regulation of physiological processes in organisms. To handle this information, computer aided integration of the results is of utmost importance in order to d- cover novel concepts that ultimately need to be tested experimentally.

The findings discussed by the learned contributors are relevant for a basic understanding of disorders such as heat injury, hypertension, and excess salt intake. A unique reference on the neurobiology of body fluid homeostasis, this volume is certain to fuel additional research and stimulate further debate on the topic.
Book Synopsis The Impact of Food Bioactives on Health by : Kitty Verhoeckx
Download or read book The Impact of Food Bioactives on Health written by Kitty Verhoeckx and published by Springer. This book was released on 2015-04-29 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Infogest” (Improving Health Properties of Food by Sharing our Knowledge on the Digestive Process) is an EU COST action/network in the domain of Food and Agriculture that will last for 4 years from April 4, 2011. Infogest aims at building an open international network of institutes undertaking multidisciplinary basic research on food digestion gathering scientists from different origins (food scientists, gut physiologists, nutritionists...). The network gathers 70 partners from academia, corresponding to a total of 29 countries. The three main scientific goals are: Identify the beneficial food components released in the gut during digestion; Support the effect of beneficial food components on human health; Promote harmonization of currently used digestion models Infogest meetings highlighted the need for a publication that would provide researchers with an insight into the advantages and disadvantages associated with the use of respective in vitro and ex vivo assays to evaluate the effects of foods and food bioactives on health. Such assays are particularly important in situations where a large number of foods/bioactives need to be screened rapidly and in a cost effective manner in order to ultimately identify lead foods/bioactives that can be the subject of in vivo assays. The book is an asset to researchers wishing to study the health benefits of their foods and food bioactives of interest and highlights which in vitro/ex vivo assays are of greatest relevance to their goals, what sort of outputs/data can be generated and, as noted above, highlight the strengths and weaknesses of the various assays. It is also an important resource for undergraduate students in the ‘food and health’ arena.
Book Synopsis Organismal Homeostasis by : Christopher J. Paradise
Download or read book Organismal Homeostasis written by Christopher J. Paradise and published by Momentum Press. This book was released on 2016-04-27 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organisms maintain homeostasis in a variety of ways. In the first part of this book, mammals are shown to regulate their body temperatures through homeostatic mechanisms. The data from thermoregulation experiments that demonstrated the role of neurons in body temperature homeostasis are examined. The second part of this book discusses how organisms allocate the limited energy that is available to them for survival, growth, or reproduction. Excess energy in individuals can translate to growth of populations: if enough remains after survival and growth, it can be allocated to reproduction. However, even closely related organisms may have different strategies for allocating resources that are dependent upon the environmental conditions in which they exist.

Book Synopsis Homeostatic Control of Brain Function by : Detlev Boison
Download or read book Homeostatic Control of Brain Function written by Detlev Boison and published by Oxford University Press. This book was released on 2016 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: Homeostatic Control of Brain Function offers a broad view of brain health and diverse perspectives for potential treatments, targeting key areas such as mitochondria, the immune system, epigenetic changes, and regulatory molecules such as ions, neuropeptides, and neuromodulators. Loss of homeostasis becomes expressed as a diverse array of neurological disorders. Each disorder has multiple comorbidities - with some crossing over several conditions - and often disease-specific treatments remain elusive. When current pharmacological therapies result in ineffective and inadequate outcomes, therapies to restore and maintain homeostatic functions can help improve brain health, no matter the diagnosis. Employing homeostatic therapies may lead to future cures or treatments that address multiple comorbidities. In an age where brain diseases such as Alzheimer's or Parkinson's are ever present, the incorporation of homeostatic techniques could successfully promote better overall brain health. Key Features include · A focus on the homeostatic controls that significantly depend on the way one lives, eats, and drinks. · Highlights from emerging research in non-pharmaceutical therapies including botanical medications, meditation, diet, and exercise. · Incorporation of homeostatic therapies into existing basic and clinical research paradigms. · Extensive scientific basic and clinical research ranging from molecules to disorders. · Emerging practical information for improving homeostasis. · Examples of homeostatic therapies in preventing and delaying dysfunction. Both editors, Detlev Boison and Susan Masino, bring their unique expertise in homeostatic research to the overall scope of this work. This book is accessible to all with an interest in brain health; scientist, clinician, student, and lay reader alike.

Book Synopsis Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals by : National Academies of Sciences, Engineering, and Medicine
Download or read book Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-05-04 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine mammals face a large array of stressors, including loss of habitat, chemical and noise pollution, and bycatch in fishing, which alone kills hundreds of thousands of marine mammals per year globally. To discern the factors contributing to population trends, scientists must consider the full complement of threats faced by marine mammals. Once populations or ecosystems are found to be at risk of adverse impacts, it is critical to decide which combination of stressors to reduce to bring the population or ecosystem into a more favorable state. Assessing all stressors facing a marine mammal population also provides the environmental context for evaluating whether an additional activity could threaten it. Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals builds upon previous reports to assess current methodologies used for evaluating cumulative effects and identify new approaches that could improve these assessments. This review focuses on ways to quantify exposure-related changes in the behavior, health, or body condition of individual marine mammals and makes recommendations for future research initiatives.

Book Synopsis Allostasis, Homeostasis, and the Costs of Physiological Adaptation by : Jay Schulkin
Download or read book Allostasis, Homeostasis, and the Costs of Physiological Adaptation written by Jay Schulkin and published by Cambridge University Press. This book was released on 2004-10-25 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of homeostasis, the maintenance of the internal physiological environment of an organism within tolerable limits, is well established in medicine and physiology. In contrast, allostasis is a relatively new idea of 'viability through change'. With allostatic regulation by cephalic involvement, the body adapts to potentially diverse and dangerous situations through the activation of neural, hormonal, or immunological mechanisms. Allostasis explains how regulatory events maintain organismic viability, or not, in diverse contexts with varying set points of bodily needs and competing motivations. This 2005 book introduces the concept of allostasis and sets it alongside traditional views of homeostasis. It addresses basic regulatory systems and examines the behavior of bodily regulation under duress. The basic concepts of physiological homeostasis are integrated with disorders like depression, stress, anxiety and addiction. It will therefore appeal to graduate students, medical students and researchers working in physiology, epidemiology, endocrinology, neuroendocrinology, neuroscience, and psychology.

Book Synopsis Sex and Gender Factors Affecting Metabolic Homeostasis, Diabetes and Obesity by : Franck Mauvais-Jarvis
Download or read book Sex and Gender Factors Affecting Metabolic Homeostasis, Diabetes and Obesity written by Franck Mauvais-Jarvis and published by Springer. This book was released on 2017-12-08 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides a reference for years to come, written by world-renowned expert investigators studying sex differences, the role of sex hormones, the systems biology of sex, and the genetic contribution of sex chromosomes to metabolic homeostasis and diseases. In this volume, leaders of the pharmaceutical industry present their views on sex-specific drug discovery. Many of the authors presented at the Keystone Symposium on “Sex and gender factors affecting metabolic homeostasis, diabetes and obesity” to be held in March 2017 in Lake Tahoe, CA. This book will generate new knowledge and ideas on the importance of gender biology and medicine from a molecular standpoint to the population level and to provide the methods to study them. It is intended to be a catalyst leading to gender-specific treatments of metabolic diseases. There are fundamental aspects of metabolic homeostasis that are regulated differently in males and females, and influence both the development of diabetes and obesity and the response to pharmacological intervention. Still, most preclinical researchers avoid studying female rodents due to the added complexity of research plans. The consequence is a generation of data that risks being relevant to only half of the population. This is a timely moment to publish a book on sex differences in diseases as NIH leadership has asked scientists to consider sex as a biological variable in preclinical research, to ensure that women get the same benefit of medical research as men.
