This book provides a comprehensive look at nonhuman primate social inequalities as models for health differences associated with socioeconomic status in humans. The benefit of the socially-housed monkey model is that it provides the complexity of hierarchical structure and rank affiliation, i.e. both negative and positive aspects of social status. At the same time, nonhuman primates are more amenable to controlled experiments and more invasive studies that can be used in human beings to examine the effects of low status on brain development, neuroendocrine function, immunity, and eating behavior. Because all of these biological and behavioral substrates form the underpinnings of human illness, and are likely shared among primates, the nonhuman primate model can significantly advance our understanding of the best interventions in humans.
This volume developed from a Workshop on Natural Locomotion in Fluids and on Surfaces: Swimming, Flying, and Sliding which was held at the Institute for Mathematics and its Applications (IMA) at the University of Minnesota, from June 1-5, 2010. The subject matter ranged widely from observational data to theoretical mechanics, and reflected the broad scope of the workshop. In both the prepared presentations and in the informal discussions, the workshop engaged exchanges across disciplines and invited a lively interaction between modelers and observers. The articles in this volume were invited and fully refereed. They provide a representative if necessarily incomplete account of the field of natural locomotion during a period of rapid growth and expansion. The papers presented at the workshop, and the contributions to the present volume, can be roughly divided into those pertaining to swimming on the scale of marine organisms, swimming of microorganisms at low Reynolds numbers, animal flight, and sliding and other related examples of locomotion.
This two-volume book is an up-to-date revision of methods and principles of phylogenetic analysis of morphological data. It is also a general guide for using the computer program TNT in the analysis of such data. The book covers the main aspects of phylogenetic analysis, and general methods to compare classifications derived from molecules and morphology. Practical application of all principles discussed is illustrated by reference to TNT, a freely available software package that can perform all the steps needed in a phylogenetic analysis. Key Features Provides in depth discussion of the connections between hypotheses of homology and the parsimony criterion Helps understand the basis for designing different aspects of a morphological study, from hints on delimiting the problem and data collecting, to character definitions and analysis Discusses the applicability of statistical models coopted from sequence analysis to the analysis of morphological data Gives detailed descriptions of the principles behind algorithms for evaluating and searching phylogenetic trees Presents extensive information on commands and options of the TNT computer program
This book is devoted to the welfare of invertebrates, which make up 99% of animal species on earth. Addressing animal welfare, we do not often think of invertebrates; in fact we seldom consider them to be deserving of welfare evaluation. And yet we should. Welfare is a broad concern for any animal that we house, control or utilize - and we utilize invertebrates a lot. The Authors start with an emphasis on the values of non-vertebrate animals and discuss the need for a book on the present topic. The following chapters focus on specific taxa, tackling questions that are most appropriate to each one. What is pain in crustaceans, and how might we prevent it? How do we ensure that octopuses are not bored? What do bees need to thrive, pollinate our plants and give us honey? Since invertebrates have distinct personalities and some social animals have group personalities, how do we consider this? And, as in the European Union's application of welfare consideration to cephalopods, how do the practical regulatory issues play out? We have previously relegated invertebrates to the category 'things' and did not worry about their treatment. New research suggest that some invertebrates such as cephalopods and crustaceans can have pain and suffering, might also have consciousness and awareness. Also, good welfare is going to mean different things to spiders, bees, corals, etc. This book is taking animal welfare in a very different direction. Academics and students of animal welfare science, those who keep invertebrates for scientific research or in service to the goals of humans, as well as philosophers will find this work thought-provoking, instructive and informative.
The coastal and ocean ecosystem is a significant feature of our planet and provides a source of food for much of life on Earth. Millions of species have been, and are still being discovered in the world's oceans. Among these zooplankton serve as secondary producers and are significant as they form pelagic food links and act as indicators of water masses. They constitute the largest and most reliable source of protein for most of the ocean's fishes. As such, their absence or depletion often affects fishery. In many countries, the decline in fishery has been attributed to reduced plankton populations. Furthermore, trillions of tiny copepods produce countless faecal pellets contributing greatly to the marine snow and therefore accelerating the flow of nutrients and minerals from the surface waters to the seabed. They are phylogenetically highly successful groups in terms of phylogenetic age, number of living species and success of adaptive radiation. A study of the basic and applied aspects of zooplankton would provide an index of the fishery potential and applications, offering insights into ocean ecology to safeguard food supplies and livelihoods of the millions of people living in coastal areas. For this reason, we need to understand all the facets of zooplankton as well as their interactions with atmosphere and other life forms, including human. In this context, this book discusses the basic and applied aspects of zooplankton, especially taxonomy, mosquitocidal activity, culture, analysis of nutritional, pigments and enzyme profile, preservation of copepods eggs, bioenrichment of zooplankton and application of zooplankton in sustainable aquaculture production, focusing on novel biofloc-copefloc technologies, and the impact of acidification and microplastics on zooplankton. Offering a comprehensive overview of the current issues and developments in the field of environmental and commercial applications, this book is a valuable resource for researchers, aquaculturists, environmental mangers wanting to understand the importance of zooplankton and develop technologies for the sustainable production of fish and other commodities to provide food and livelihoods for mankind.

This is a careful study of obstetrical mechanics in monkeys, apes, and extinct hominids in order to understand the present crisis in human reproduction. Current obstetrical problems have an anthropological origin. Cesarean section, almost unknown at the beginning of the century, is now considered necessary in more than 25% of deliveries. By studying the evolution of anatomical structures and the mode of delivery among other primates, strong reasons are apparent for the present crisis in human labor and delivery. This unique study points the way to further evolution of the human birth process.

Machine learning is concerned with the analysis of large data and multiple variables. However, it is also often more sensitive than traditional statistical methods to analyze small data. The first volume reviewed subjects like optimal scaling, neural networks, factor analysis, partial least squares, discriminant analysis, canonical analysis, and fuzzy modeling. This second volume includes various clustering models, support vector machines, Bayesian networks, discrete wavelet analysis, genetic programming, association rule learning, anomaly detection, correspondence analysis, and other subjects. Both the theoretical bases and the step by step analyses are described for the benefit of non-mathematical readers. Each chapter can be studied without the need to consult other chapters. Traditional statistical tests are, sometimes, priors to machine learning methods, and they are also, sometimes, used as contrast tests. To those wishing to obtain more knowledge of them, we recommend to additionally study (1) Statistics Applied to Clinical Studies 5th Edition 2012, (2) SPSS for Starters Part One and Two 2012, and (3) Statistical Analysis of Clinical Data on a Pocket Calculator Part One and Two 2012, written by the same authors, and edited by Springer, New York.

According to Egyptian mythology, when the god Re cried, his tears turned into bees upon touching the ground. Beyond the realm of myth, the honey bee is a surprisingly common and significant motif in Egyptian history, playing a role in the mythology, medicine, art, and food of the ancient culture. In The Tears of Re: Beekeeping in Ancient Egypt, entomologist Gene Kritsky presents the first full-length discussion of the ways in which bees were a part of life in ancient Egypt, shedding light on one of the many mysteries of the ancient world. Kritsky delves into ancient Egypt's complex society, revealing that bees had a significant presence in everything from death rituals to trade. In fact, beekeeping was a state-controlled industry, and in certain instances honey could even be used to pay taxes! Honey was used both to sweeten foods and treat cuts, and was sometimes used as a tribute or offering. From the presence of bees in paintings and hieroglyphs in tombs to the use of beeswax in a variety of products, bees had a significant presence in ancient Egyptian culture. Richly illustrated and engagingly written, The Tears of Re will appeal to anyone with a passion for beekeeping, Egypt, or the ancient world.

With over 43,000 species, spiders are the largest predacious arthropod group. They have developed key characteristics such as multi-purpose silk types, venoms consisting of hundreds of components, locomotion driven by muscles and hydraulic pressure, a highly evolved key-lock mechanism between the complex genital structures, and many more unique features. After 300 million years of evolutionary refinement, spiders are present in all land habitats and represent one of the most successful groups of terrestrial organisms. Ecophysiology combines functional and evolutionary aspects of morphology, physiology, biochemistry and molecular biology with ecology. Cutting-edge science in spiders focuses on the circulatory and respiratory system, locomotion and dispersal abilities, the immune system, endosymbionts and pathogens, chemical communication, gland secretions, venom components, silk structure, structure and perception of colours as well as nutritional requirements. Spiders are valuable indicator species in agroecosystems and for conservation biology. Modern transfer and application technologies research spiders and their products with respect to their value for biomimetics, material sciences, and the agrochemical and pharmaceutical industries.
