This book outlines the principles of flight, of birds in particular. It describes a way of simplifying the mechanics of flight into a practical computer program, which will predict in some detail what any bird, real or hypothetical, can and cannot do. The Flight program, presented on the companion website, generates performance curves for flapping and gliding flight, and simulations of long-distance migration and accounts successfully for the consumption of muscles and other tissues during migratory flights. The program is effectively a working model of a flying bird (or bat or pterosaur) and is the skeleton around which the book is built. The book provides a wider background and then explains how Flight works and shows how to set up and test hypotheses generated by the program.
The book and the program are based on adapting the conventional (and well-tested) thinking of aeronautical engineers to the biological problems of bird flight. Their primary aim is to convince biologists that this is the appropriate way to handle problems that involve flight, to make the engineering background accessible to biologists, and to provide a tool kit in the shape of the Flight program, which they can use to solve practical problems involving bird flight and migration. In addition, the book will be readily accessible to engineers who want to know how birds work, and should be of interest to the ever-growing community working on flapping "micro air vehicles" (MAVs). The program can be used to predict the flight performance and capabilities of reconstructed fossil birds and pterosaurs, flying in ancient atmospheres that differ from present conditions, and also, of course, to predict and account for the results of experiments and observations on living birds and bats.

The eye is a complex sensory organ, which enables visual perception of the world. Thus the eye has several tissues that do different tasks. One of the most basic aspects of eye function is the sensitivity of cells to light and its transduction though the optic nerve to the brain. Different organisms use different ways to achieve these tasks. In this sense, eye function becomes a very important evolutionary aspect as well. This book presents the different animal models that are commonly used for eye research and their uniqueness in evaluating different aspects of eye development, evolution, physiology and disease.
* Presents information on the major animal models used in eye research including invertebrates and vertebrates
* Provides researchers with information needed to choose between model organisms
* Includes an introductory chapter on the different types of eyes, stressing possible common molecular machinery

To study physiology is to examine how organisms have evolved solutions to the business of living in an inanimate world. Our world is and has always been dominated by physical and chemical forces. A physicist might tell us that all things are physical, while a chemist is more concerned with the elementary nature of reactions. A physical chemist sees the bonds between these views, and a biochemist draws out the organic symphony of the vital pathways. A structural biologist adds shape to the chemical building blocks of life, while a molecular biologist tinkers with these structures.This book is intended as a resource for students and researchers interested in developmental biology and physiology and specifically addresses the larval stages of fish. Fish larvae (and fish embryos) are not small juveniles or adults. Rather they are transitionary organisms that bridge the critical gap between the single-celled egg and sexually immature juvenile. Fish larvae represent the stage of the life cycle that is used for differentiation, feeding and distribution.This book aims at providing a single-volume treatise that explains how fish larvae develop and differentiate, how they regulate salt, water and acid-base balance, how they transport and exchange gases, acquire and utilise energy, how they sense their environment, and move in their aquatic medium, how they control and defend themselves, and finally how they grow up.

This illustrated introduction to Central American Chironomidae offers extensive photographic material, as well as detailed morphological and ecological descriptions of chironomid subfossils found in Central American lake sediments. The book uniquely provides two identification keys: one for living larvae occurring (or potentially being present) in Central America and one for the recorded subfossil remains, using limited morphological characters. Paleolimnological investigations using chironomid remains have undergone a resurgence of interest, and this taxonomic guide will aid the thorough analysis of the diversity and distribution of the taxa encountered to date in Central America. Out of the total 64 described genera, the book brings 20 endemic genera, and more than half of the presented morphotypes are new. Plates are included for each taxon with generic characters and also provide a key to morphotypes, if present, their specific characters, distribution, and ecology. Authored by a (paleo)limnologist and a taxonomist, the guide draws on a thorough taxonomical knowledge of the region's recent chironomid fauna. It uses a paleolimnological approach to transmit this information to morphotypes that can be linked with ecology and used to reconstruct the past development of nature. The book thus helps paleo-workers and taxonomists to learn more about these fascinating insects and, through them, to discover the world around us. Providing a comprehensive reference for aquatic ecologists, paleolimnologists, students, and researchers, the guide will also be of interest to non-academic professionals working on applied research and biomonitoring of lakes. It will be useful for people studying both recent and subfossil material, not only in Central America, but in the whole Neotropical region.

With advancing technology, students are getting accustomed to evermore portable resources on their phones - quick reference texts are therefore required to compete with this shift in approach. Where easy layouts assist with faster clinical reasoning, or ambulatory practice provides poor signal, printed text still out-competes digital technologies. Affordable and concise, this visually engaging concise textbook is easy to use as a revision aid and take on placement (veterinary EMS - Extra-mural studies). The spiralbound format allows it to lay flat when referred to in practice, adding another level of practical use. The emphasis will be on those things regularly available to general practitioners with minimal information of advanced techniques. Similar to the popular MiniVet guide, but for Equine: fills a gap for a concise, quick and easy practical reference for students in Equine practice. There’s a clear market for books that focus on best practices, protocols, flowcharts and treatment management for equine pathologies and thus provide a direct clinical approach to cases and clinical reasoning. The book is clearly divided into sub-sections, i.e., etiology, differential diagnosis etc. This makes it simple to follow and useful to apply to cases. The high quantity of pictures and diagrams help understanding of each different condition. International readership Can be bought as a single text or as a package with other books in the Equine Concise Textbook series Distills key information from 'Equine Clinical Medicine, Surgery and Reproduction 2E' which has previously been out of the student price range.

Laboratory animals are becoming increasingly important for biomedical research. It is said that approximately 70% of biomedical research is associated with the use of experimental animals. Laboratory animal research not only expands our knowledge of science, but also greatly improves human and animal health. The field of laboratory animal science is ever-growing and changing as new experimental techniques are developed and new animal models are created. It is essential to know not only the biological features of each laboratory animal but also how to use and care for them responsibly in order to perform high-quality experiments. Courses in beginning Laboratory Animal Science are starting to be offered in many universities throughout the world. However, a practical introductory textbook that contains state-of-the-art techniques is still lacking. Fundamentals of Laboratory Animal Science provides comprehensive information on the principles and practices of using laboratory animals for biomedical research. Each individual chapter focuses on a key sub-discipline of laboratory animal science: animal welfare and best humane care practices in the laboratory; the quality control of laboratory animals; the anatomy, physiology, and husbandry of commonly used species; the principles of creating and using animal models for studying human diseases; practical techniques used for laboratory animal experiments; experimental design; and animal experimentation management. Knowledge of this broad spectrum of concepts and skills will ensure research goes smoothly while greatly reducing animal pain and distress. Well-illustrated and thoroughly referenced, this book will serve not only as a standard textbook but also as a handy guide for veterinarians, researchers, animal care staff, administrators, and other professionals who are involved in laboratory animal science.

Erythrocytes of the Rhesus and Cynomolgus Monkeys addresses the morphologic, quantitative, and generative aspects of the erythrocytes of the rhesus monkey Macaca mulatta and the cynomolgus monkey Macaca fascicularis (long-tailed macaque, crab-eating monkey). These two species are the most commonly selected nonhuman primates for basic science and clinical medical investigations. The hemopoietic cells of man and the rhesus monkey display an intimate homogeneity. Their functional activities are close and at times identical. The cynomolgus monkey was enlisted in biomedical studies at a time when rhesus monkeys were not available in sufficient quantities. It has gained increased use in the Far East and in the Western world. It is, for example, employed in the current development of a vaccine against the deadly Ebola virus. The authors of the book discuss the erythropoietic profiles of normal and abnormal macaques of both sexes and of all age groups as investigated with contemporary electronic methodologies. They cover the role of stress as it is perceived by the monkey and how it impacts erythrocellular values, and how to train the monkey to be a cooperative, unperturbed subject for hematologic study. Additional topics include the role of medication in deriving normal physiologic erythrocellular data, the development of the precursors of the erythrocyte (normoblasts), the morphologic analysis of the megaloblastic series of abnormal erythroid cells, the analysis of erythropoiesis in bone marrow, the relationship of the simian immunodeficiency virus and erythropoiesis, erythrocyte life span, and parasitic invasion of the red cell.

Mammalian oocytes occupy a critical nexus in reproduction as they not only contribute half the genetic makeup of the embryo but also provide virtually all of the cytoplasmic building blocks required for sustaining embryogenesis. The journey that transforms a primordial germ cell into a mature oocyte (or egg) capable of fertilisation and embryonic development is of unrivalled complexity. The end-product of this remarkable developmental process is the "mature" egg, now replete with macromolecules and organelles, and poised to support embryonic development if fertilisation should occur. Given the importance of the oocyte for embryonic development, it is of no surprise that the oocyte holds centre stage in fertility clinics and greatly influences the outcome of assisted reproductive treatments (ARTs). Mammalian Oocyte Regulation: Methods and Protocols provides a highly diverse compendium of detailed methodologies - primarily focusing on the murine model but also including chapters on human oocytes - for enabling researchers to interrogate every aspect of mammalian oocyte development including recombination, meiotic maturation, oocyte substrate uptake, chromosomal segregation and fertilisation. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Mammalian Oocyte Regulation: Methods and Protocols serves as an ideal guide to novice oocyte researchers, experts who wish to add another dimension to their established portfolio, as well as the wider research community.

The authors are noted neurobiologists and active researchers from the United States, Japan, and the United Kingdom.

Divided into five sections and containing scientific photographs, line drawings, tables, color illustrations, and graphs, this interesting and timely text covers the neuroplastic effects of steroid hormones throughout the lifetime of various animal models, such as bees, fish, lizards, turtles, birds, mice, rats, and primates. These sections focus on:
Ÿ The development and differentiation of neuroendocrine systems
Ÿ Steroid dependent brain differentiation
Ÿ The central regulation of hormone secretion
Ÿ Steroid hormones and neuroplasticity in the mature brain
Ÿ Steroid mediated mechanisms of cell growth and survival

Ecologists have always believed, at least to a certain extent, that physiological mechanisms serve to underpin ecological patterns. However, their importance has traditionally been at best underestimated and at worst ignored, with physiological variation being dismissed as either an irrelevance or as random noise/error. Spicer and Gaston make a convincing argument that the precise physiology does matter

In contrast to previous works which have attempted to integrate ecology and physiology, Physiological Diversity adopts a completely different and more controversial approach in tackling the physiology first before moving on to consider the implications for ecology. This is timely given the recent and considerable interest in the mechanisms underlying ecological patterns. Indeed, many of these mechanisms are physiological.

This textbook provides a contemporary summary of physiological diversity as it occurs at different hierarchical levels (individual, population, species etc.), and the implications of such diversity for ecology and, by implication, evolution. It reviews what is known of physiological diversity and in doing so exposes the reader to all the key works in the field. It also portrays many of these studies in a completely new light, thereby serving as an agenda for, and impetus to, the future study of physiological variation.

"Physiological Diversity" will be of relevance to senior undergraduates, postgraduates and professional researchers in the fields of ecology, ecological physiology, ecotoxicology, environmental biology and conservation. The book spans both terrestrial and marine systems.

Molecular mechanisms in visual transduction is presently one of the most intensely studied areas in the field of signal transduction research in biological cells. Because the sense of vision plays a primary role in animal biology, and thus has been subject to long evolutionary development, the molecular and cellular mechanisms underlying vision have a high degree of sensitivity and versatility. The aims of visual transduction research are first
to determine which molecules participate, and then to understand how they act in concert to produce the exquisite electrical responses of the photoreceptor cells.
Since the 1940s 1] we have known that rod vision begins with the capture of a quantum of energy, a photon, by a visual pigment molecule, rhodopsin. As the function of photon absorption is to convert the visual pigment molecule into a G-protein activating state, the structural details of the visual pigments must be
explained from the perspective of their role in activating their specific G-proteins. Thus, Chapters 1-3 of this Handbook extensively cover the physico-chemical molecular characteristics of the vertebrate rhodopsins. Following photoconversion and G-protein activation, the phototransduction cascade leads to modifications of the population of closed and open ion channels in the photoreceptor plasma membrane, and thereby to the electrical response. The nature of the channels of vertebrate photoreceptors is examined in Chapter 4, and Chapter 5 integrates the present body of knowledge of the activation steps in the cascade into a quantitative framework. Once the phototransduction cascade is activated, it must be subsequently silenced. The various molecular mechanisms participating in inactivation are
treated in Chapters 1-4 and especially Chapter 5. Molecular biology is now an indispensable tool in signal transduction studies. Numerous vertebrate (Chapter 6) and invertebrate (Chapter 7) visual pigments have been characterized and cloned. The genetics and evolutionary aspects of this great subfamily of G-protein activating receptors are intriguing as they present a natural probe for the intimate relationship between structure and function of the visual pigments. Understanding the spectral characteristics from the molecular composition can be expected to

This title offers an approach to the subject area by fully integrating the field of animal behaviour and biomechanics. It demonstrates how the study of biomechanics is useful in understanding, evaluating and making predictions about animal behaviour. The book examines how the mechanical limits of movement constrain and determine animal behaviour, for example swimming strategy of aquatic vertebrates, walking energetics in invertebrates, light mechanics and migration performance in birds.
