Hunting with falcons for houbara bustards was an integral part of traditional life in the desert. Over the last few decades, this magnificent bird - so well adapted to the desert environment - has become an endangered species, due both to continued hunting and to the degradation of its habitat by domestic livestock. This book highlights the achievements of the National Wildlife Research Center of Saudi Arabia in securing the survival of the species through captive breeding, with the aim of reintroducing the houbara to the wild. The breeding programme has proved to be the greatest source of information yet available on the bird, yielding important data not obtainable from wild houbaras. Propagation of the Houbara Bustard is a practical 'how-to' manual for breeding the bird in captivity. It also presents and summarises the background data on houbara diet, behaviour, physiology, reproductive biology and veterinary care that have enabled the breeding programme to succeed in the short span of eight years. It will be of interest not only to breeders of houbara and other bustard species, but to all those who are studying or managing wild populations.
For nearly 50 years, pest control was mostly based on broad-spectrum conv- tional insecticides such as organochlorines, organophosphates, carbamates and pyrethroids. However, the severe adverse effects of pesticides on the environment, problems of resistance reaching crisis proportions and public protests led to stricter regulations and legislation aimed at reducing their use. Ways to reduce the use of synthetic pesticides in plant protection and to use more alternative and novel me- ods for pest control or biorational control are the challenges of pest control for the twenty-first century. The term biorational (biological + rational) pesticides can be defined as the use of specific and selective chemicals, often with a unique modes of action, that are compatible with natural enemies and the environment, with minimal effect on n- target organisms. Biorational control is based on a diversity of chemical, biological and physical approaches for controlling insect pests which results in minimum risk to man and the environment.
Based on the presentations given by well-known specialists at a
recent multidisciplinary conference of developmental
psychobiologists, obstetricians, and physiologists, this book is
the first exhaustive attempt to synthesize the present scientific
knowledge on fetal behavior. Utilizing a psychobiological analytic
approach, it provides the reader with an overview of the
perspectives, hypotheses, and experimental results from a group of
basic scientists and clinicians who conduct research to elucidate
the role of fetal behavior in development. Experimental and
clinical as well as human and animal data are explored via
comparative developmental analysis. The ontogeny of fetal
spontaneous activity -- via the maturation of "behavioral states"
-- and of fetal responsiveness to sensory stimulation is studied in
detail. Results are provided from studies of embryonic/fetal and
newborn behavior in chicks, rats, sheep, primates, and humans.
Knowledge of fetal behavior is crucial to the obstetrician,
neonatologist, developmental psychologist, and even the future
parents, in order to follow and assess the gradual development of
spontaneous responsive movements of the fetus. While assessing this
important information, this text also examines the neuro-behavioral
events taking place during the fetal period as an aid to
understanding normal and pathological life span development.
A succinct reference for those assessing and managing the reproductive functionality of male animals, this practical manual contains both generic and species-specific information suitable for widespread worldwide application.

A simple, concise 'go-to' for the useful techniques and procedures of animal andrology, this book: - Covers a wide range of species, including cattle, sheep, goats, pigs, horses, water buffalo, camelids and dogs - Provides normal values and ranges for important male reproductive traits, as well as guidelines for breeding soundness evaluations - Includes extra supplementary illustrations, protocols and resources through accompanying website to enable further learning. With information presented in a manner that will remain useful for years to come, Manual of Animal Andrology is an essential resource for veterinarians, theriogenologists, animal breeders, and students of veterinary and animal sciences.
Dating back to the early Cambrian period, crustaceans had ample time to undertake endless experimentation with form and function. Today, no other group of plants or animals on the planet exhibit the range of morphological diversity seen among extant Crustacea. With more than 52,000 species, they are placed fourth in terms of overall species diversity. This book comprehensively elucidates the reproduction and development of all the taxonomic groups of Crustacea and bridges the gap between conventional zoologists and molecular biologists. Reproductive modes from the point of embryonic stem cells and primordial germ cells is discussed with a special section on cysts.
The animals loosely termed fish constitute more than half of all known vertebrate species. There are approximately 27,000 described living species of bony fishes (Euteleostomi = Osteichthyes), about 70 species of hagfishes and some 34 species of lampreys. Approximately 970 species are chondrichthyans, the sharks and their relatives, which were the subject of volume 3 in this series. It is perhaps because fishes live in a buoyant medium, whether it be fresh or sea water, that they show a diversity in body shapes that is unparalleled by other vertebrates. There is also a unique diversity in the modes of reproduction, whether by external or internal fertilization, and this, with the morphology and fine structure of the reproductive system and its components, is the subject of Part A. Part B deals with complementary topics: testes, sperm, and sperm competition; endocrinology of reproduction; pheromones and reproduction; copulatory structures: taxonomic overview and the potential for sexual selection; sexual selection: signaling and courtship; adaptation and evolution of reproductive mode in copulating cottoid species; fertilization; sex determination; parental care; reproduction in relation to conservation and exploitation of marine fishes; Cryopreservation of Gametes; Embryogenesis and Development; and Molecular Genetics of Development.
With the decline in world fish stocks, our knowledge of fish reproduction has become fundamental. Reproduction is an essential commitment to future generation. It is also a continuous development process throughout ontogeny, requiring energetic, ecological, physiological, anatomical, biochemical and endrocrinological adaptations. The first chapters highlight important issues affecting fish normal ways of reproductive development; details would focus on species living in opposite environments, such as tropical and polar fishes; far related, as teleosts and cartilaginous fishes; and finally, fish having different reproductive strategies. Thereafter, since many fishes live in detrimental environments, mainly induced by the continuous input of xenobiotic substances into waterways, the authors found it highly pertinent to include this topic. Herein, the authors fix their attention on the factors and mechanisms that may well affect reproductionrelated hormonal systems as also on known consequences for fish living i
Aspects of reproduction covered in this volume include classification and phylogeny as revealed by molecular biology; anatomy of the male reproductive tract and organs; anatomy and evolution of copulatory structures; development and anatomy of the female reproductive tract; endocrinology of reproduction; ovarian dynamics and follicle development; spermatogenesis and testicular cycles; avian spermatozoa: structure and phylogeny; testis size, sperm size and sperm competition and lastly, fertilization.
Although all living beings modify their environment, human beings have acquired the ability to do so on a superlative space-time scale. As a result of industrialization and the use of new technologies, the anthropogenic impact has been increasing in the last centuries, causing reductions in the sizes or the extinction of numerous wild populations. In this sense, from the field of conservation genetics, various efforts have been made in recent decades to provide new knowledge that contributes to the conservation of populations, species, and habitats. In this book, we summarize the concrete contributions of researchers to the conservation of the Neotropical mammals using Molecular Ecology techniques. The book is divided into three major sections. The first section provides an up-to-date review of the conservation status of Neotropical mammals, the applications of the molecular markers in its conservation, and the use of non-invasive and forensic genetic techniques. The second and third sections present, respectively, a series of case studies in various species or taxonomic groups of Neotropical mammals.
Prenatal life is the period of maximal development in animals, and it is well recognised that factors that alter development can have profound effects on the embryonic, fetal and postnatal animal. Scientists involved in research on livestock productivity have for decades studied postnatal consequences of fetal development on productivity. Recently, however, there has been a surge in interest in how to manage prenatal development to enhance livestock health and productivity. This has occurred largely due to the studies that show human health in later life can be influenced by events during prenatal life, and establishment of the Fetal Origins and the Thrifty Phenotype Hypotheses. This book, Managing the Prenatal Environment to Enhance Livestock Productivity reviews phenotypic consequences of prenatal development, and provides details of mechanisms that underpin these effects in ruminants, pigs and poultry. The chapters have been divided into three parts: Quantification of prenatal effects on postnatal productivity, mechanistic bases of postnatal consequences of prenatal development and regulators of fetal and neonatal nutrient supply. Managing the Prenatal Environment to Enhance Livestock Productivity is a reference from which future research to improve the level of understanding and capacity to enhance productivity, health and efficiency of livestock in developing and developed countries will evolve. It is particularly timely given the development of molecular technologies that are providing new insight into regulation and consequences of growth and development of the embryo, fetus and neonate.
This book presents a concept for implementing a mass balance approach toward developing an effective eco-friendly, livestock farming system independent of external energy input. In this context it describes a modern, integrated farming system, and includes comprehensive technical information explaining the design and evaluation of manure management systems, and modeling and operational tools. It first discusses the mass balance operating process, highlighting the difference between imported and exported mass across the farm boundary. Estimating mass balance can provide critical information for (comprehensive) nutrient management planning and for managing the movement of nutrients and manure. It then explains the estimation of whole-farm P mass balance using a suitable model system. The subsequent chapters provide updated information on management aspects of livestock-farming and generation of multiple job opportunities, and also explore various aspects of livestock farming operational protocols like housing and management; nurture of rams, ewes and lambs, new born calves and heifers; care of buck, doe and kid- nutrition flushing; concept zero grazing-systems; disease control and management; integrated goat farming; and crop-livestock integration. Further, the book addresses crop-livestock integration; energy autonomy in cattle farming; value added biopharmaceuticals from cattle farming; CAPEX for cattle farming; concepts of cattle farming; detrimental effects of the industry; topographic and edaphic factors, and thermal stress on livestock growth and development; socioeconomic development; and water requirements for livestock. The book concludes with the most important issue in the field of agriculture and veterinary science: "Livestock Farming with Care," describing sustainable, eco-friendly livestock farming by highlighting issues like animal feed vs. human food; agricultural GDP vs livestock, and factors affecting the sustainability of livestock farming. Given its scope, this book is a valuable resource for researchers and students alike, and will also appeal to practitioners in the field of livestock.
This book examines the biology of tuco-tucos (Ctenomys) from an evolutionary perspective. Historically, these subterranean rodents have long attracted the attention of scientists due to its remarkable chromosomes variability and rapid diversification. A wealth of knowledge on physiology, ecology, genetics, morphology, paleontology, and taxonomy has been documented in the last 70 years through numerous single publications. In this volume, expert investigators review and frame these essays with the breadth of current understanding. The collection of chapters are presented into the major topics: i) Evolution of Ctenomys, ii) Geographic Patterns, iii) Organismal Biology, and iv) Environmental Relationships. Given its scope, the book will be of interest to both students and researchers and may stimulate further research with this exciting model on a wide range of evolutionary topics.
In the past three decades, considerable progress has been made in the mathematical analysis, modeling, and simulation of the fluid dynamics of liquid capsules and biological cells.

This book aims to be a comprehensive review of the literature on the conservation genetics of the New World crocodilians, from the biological and demographical aspects of the living species to the application of molecular techniques for conservation purposes. It covers the current status of the molecular genetics applied to phylogenetics, phylogeography, diversity, kinship and mating system, and hybridization, as well its implications for decision making with regards to the conservation of these species at academic and governmental levels. This book can be used as a guide for graduate and undergraduate students to understand how conservation genetics techniques are carried out and how they can help preserve not only crocodilians but also other living species.
This book presents a comprehensive overview of DNA barcoding and molecular phylogeny, along with a number of case studies. It discusses a number of areas where DNA barcoding can be applied, such as clinical microbiology, especially in relation to infection management; DNA database management; and plant -animal interactions, and also presents valuable information on the DNA barcoding and molecular phylogeny of microbes, algae, elasmobranchs, fishes, birds and ruminant mammals. Furthermore it features unique case studies describing DNA barcoding of reptiles dwelling in Saudi Arabian deserts, genetic variation studies in both wild and hatchery populations of Anabas testudineus, DNA barcoding and molecular phylogeny of Ichthyoplankton and juvenile fishes of Kuantan River in Malaysia, and barcoding and molecular phylogenetic analysis of indigenous bacteria from fishes dwelling in a tropical tidal river. Moreover, since prompt identification and management of invasive species is vital to prevent economic and ecological loss, the book includes a chapter on DNA barcoding of invasive species. Given its scope, this book will appeal not only to researchers, teachers and students around the globe, but also to general readers.
Drosophila melanogaster (fruit fly) is a highly versatile model with a genetic legacy of more than a century. It provides powerful genetic, cellular, biochemical and molecular biology tools to address many questions extending from basic biology to human diseases. One of the most important questions in biology is how a multi-cellular organism develops from a single-celled embryo. The discovery of the genes responsible for pattern formation has helped refine this question and has led to other questions, such as the role of various genetic and cell biological pathways in regulating the process of pattern formation and growth during organogenesis. The Drosophila eye model has been extensively used to study molecular genetic mechanisms involved in patterning and growth. Since the genetic machinery involved in the Drosophila eye is similar to humans, it has been used to model human diseases and homology to eyes in other taxa. This updated second edition covers current progress in the study of molecular genetic mechanisms of pattern formation, mutations in axial patterning, genetic regulation of growth, and more using the Drosophila eye as a model.
This is a reference handbook for young researchers exploring gene and cell therapy. Gene therapy could be defined as a set of strategies modifying gene expression or correcting mutant/defective genes through the administration of DNA (or RNA) to cells, in order to treat disease. Important advances like the discovery of RNA interference, the completion of the Human Genome project or the development of induced pluripotent stem cells (iPSc) and the basics of gene therapy are covered. This is a great book for students, teachers, biomedical researchers delving into gene/cell therapy or researchers borrowing skills from this scientific field.
Any events that challenge the survival of living organisms may be classified as stressors. These stressors could include, for example, lack of food, increased population pressure, predatory pressure, climatic events or in the case of humans, loss of a loved one, lack of financial security or uncertainty in the future. Although most physiological systems are affected by stress, those systems that regulate reproductive physiology and behaviour are the most sensitive. All multicellular organisms show a stress related effect on reproduction, although the more complex organisms, such as mammals, have the most complex effects. The objective of this book is to provide a comparative analysis of the mechanisms by which stress regulates reproduction exploring the evolution of stress perceiving systems from the simplest organisms to humans. Taking an integrated approach, utilising a genes-to-environment overview, the book examines the stressors that occur at all levels of organisation. These theories are used to examine and explain human and animal reproductive behaviour and physiology under stressful conditions providing a well-written, concise introduction to this important subject.
Reproduction is a fundamental feature of life, it is the way life persists across the ages. This book offers new, wider vistas on this fundamental biological phenomenon, exploring how it works through the whole tree of life. It explores facets such as asexual reproduction, parthenogenesis, sex determination and reproductive investment, with a taxonomic coverage extended over all the main groups - animals, plants including 'algae', fungi, protists and bacteria. It collates into one volume perspectives from varied disciplines - including zoology, botany, microbiology, genetics, cell biology, developmental biology, evolutionary biology, animal and plant physiology, and ethology - integrating information into a common language. Crucially, the book aims to identify the commonalties among reproductive phenomena, while demonstrating the diversity even amongst closely related taxa. Its integrated approach makes this a valuable reference book for students and researchers, as well as an effective entry point for deeper study on specific topics.
Building on the successful structure of the first edition, the second edition of Reproductive Technologies in Farm Animals has been totally updated and revised to provide an up to date account of the key techniques employed in manipulating reproduction in farm animals, including beef and dairy cattle, pigs, sheep, goats, buffaloes, camelids, horses and poultry. A classic introductory text to the subject, the book is based on a comprehensive review of the current literature. It: - outlines different agricultural systems and explores the ethical implications of modern farming methods; - details the many new developments, including the commercial application of sexed semen and large-scale application of in vitro produced cattle embryos; - provides a valuable synopsis of current and future reproductive technologies, such as cloning and the production of transgenic animals. This text remains key reading for students in animal science, agriculture, veterinary medicine and biology, and veterinary practitioners and farmers who wish to keep updated on developments in techniques that may be useful in their daily practice.
This book provides insight into the instances in which wildlife species can create problems. Some species trigger problems for human activities, but many others need humans to save them and to continue to exist. The text addresses issues faced by economists and politicians dealing with laws involving actions undertaken to resolve the problems of the interaction between humans and wildlife. Here, the words 'problematic species' are used in their broadest sense, as may be appreciated in the short introductions to the various sections. At times, the authors discuss special cases while always extending the discussion into a more general and broad vision. At others, they present real cutting-edge analysis of ecological topics and issues. The book will be of interest to biologists, ecologists and wildlife managers involved in research on wildlife, parks, and environmental management, as well as to government departments and agencies, NGOs and conservation wildlife organizations. Even those in contact with nature, such as hunters, herders, and farmers, will be able to find a great deal of important information. Specific case studies are selected from among the most significant and prevalent cases throughout the world. A total of 26 papers have been selected for this book, written by zoologists, biologists and ecologists. Many have an interdisciplinary approach, with contributions by economists, criminologists, technical specialists, and engineers.
This book is the final one in a set of four providing a series on controlled reproduction in farm animals. The aim of the series is to provide a general review of the literature dealing with the different ways in which reproduction in the major farm mammals can be controlled and manipulated. The four volumes are effectively an expanded and new edition of a previous work, "Controlled Breeding in Farm Animals" (Pergamon Press, 1983). However, the literature on this subject has expanded so rapidly since the time of the earlier volume, that it is now thought appropriate to publish it in four separate volumes.Buffaloes, goats, deer and camelids have been added to the species covered by the series compared to the previous book. All volumes provide comprehensive reference lists and are fully up-to-date. This final volume focuses on horses, deer and camelids (camels, llamas and alpacas). All of these animals are attracting increasing attention for either leisure pursuits, meat or fiber production. The book will appeal to reproductive physiologists and workers in animal production, animal breeding and veterinary medicine.
This open access book focuses on the linear selection index (LSI) theory and its statistical properties. It addresses the single-stage LSI theory by assuming that economic weights are fixed and known - or fixed, but unknown - to predict the net genetic merit in the phenotypic, marker and genomic context. Further, it shows how to combine the LSI theory with the independent culling method to develop the multistage selection index theory. The final two chapters present simulation results and SAS and R codes, respectively, to estimate the parameters and make selections using some of the LSIs described. It is essential reading for plant quantitative geneticists, but is also a valuable resource for animal breeders. |
