Transportation of species to areas outside their native ranges has been a feature of human culture for millennia. During this time such activities have largely been viewed as beneficial or inconsequential. However, it has become increasingly clear that human-caused introductions of alien biota are an ecological disruption whose consequences rival those of better-known insults like chemical pollution, habitat loss, and climate change. Indeed, the irreversible nature of most alien-species int- ductions makes them less prone to correction than many other ecological problems. Current reshuffling of species ranges is so great that the present era has been referred to by some as the "Homogocene" in an effort to reflect the unique mag- tude of the changes being made. These alien interlopers often cause considerable ecological and economic d- age where introduced. Species extinctions, food-web disruptions, community alte- tions, ecosystem conversion, changes in nutrient cycling, fisheries collapse, watershed degradation, agricultural loss, building damage, and disease epidemics are among the destructive - and frequently unpredictable - ecological and economic effects that invasive alien species can inflict. The magnitude of these damages c- tinues to grow, with virtually all environments heavily used by humans now do- nated by alien species and many "natural" areas becoming increasingly prone to alien invasion as well. Attention to this problem has increased in the past decade or so, and efforts to prevent or limit further harm are gaining wider scientific and political acceptance.
This comprehensive introductory text integrates evolutionary, ecological, and demographic perspectives with new results from field studies and contemporary noninvasive molecular and hormonal techniques to understand how different primates behave and the significance of these insights for primate conservation. Each chapter is organized around the major research themes in the field, with Strier emphasizing the interplay between theory, observations, and conservation issues. Examples are drawn from the "classic" primate field studies as well as more recent studies, including many previously neglected species, to illustrate the vast behavioral variation that exists across the primate order. Primate Behavioral Ecology 6th Edition integrates the impacts of anthropogenic activities on primate populations, including zoonotic disease and climate change, and considers the importance of behavioral flexibility for primate conservation. This fully updated new edition brings exciting new methods, theoretical perspectives, and discoveries together to provide an incomparable overview of the field of primate behavioral ecology and its applications to primate conservation. It is considered to be a "must read" for all students interested in primates.
The past decade has seen a steady increase in studies oflemur behavior and ecology. As a result, there is much novel information on newly studied populations, and even newly discovered species, that has not yet been published or summarized. In fact, lemurs have not been the focus of an international symposium since the Prosimian Biology Conference in London in 1972. Moreover, research on lemurs has reached a new quality by addressing general issues in behavioral ecology and evolutionary biology. Although lemurs provide important comparative information on these topics, this aspect of research on lemurs has not been reviewed and compared with similar studies in other primate radiations. Thus, as did many in the field, we felt that the time was ripe to review and synthesize our knowledge of lemur behavioral ecology. Following an initiative by Gerry Doyle, we organized a symposium at the XIVth Congress of the International Primatological Society in Strasbourg, France, where 15 contributions summarized much new information on lemur social systems and their ecological basis. This volume provides a collection of the papers presented at the Strasbourg symposium (plus two reports from recently completed field projects). Each chapter was peer-reviewed, typically by one "lemurologist" and one other biologist. The first three chapters present novel information from the first long-term field studies of three enigmatic species. Sterling describes the social organization of Daubentonia madagascariensis, showing that aye-aye ranging patterns deviate from those of all other nocturnal primates.
A presentation of all aspects of neural crest cell origins (embryological and evolutionary) development and evolution; neural crest cell behavior (migration) and anomalies (neurocristopathies and birth defects) that arise from defective neural crest development. The treatment of development will include discussions of cellular, molecular and genetic aspects of the differentiation and morphogenesis of neural crest cells and structures derived from neural crest cells. The origins of the neural crest in embryology will be discussed using the recent information on the molecular basis of the specification of the neural crest. Also presented are the advances in our understanding of the evolution of jaws from studies on lampreys and of the neural crest from studies on ascidians and amphioxus.
An enduring and popular resource, this handy publication lists all the birds to be seen in the region and provides a simple way of recording where and when you have spotted them. Pocket-sized for ease of use, it offers:
This revised, updated checklist will be sought after by the region’s twitchers at all levels.
The observation that neuropeptide Y (NPY) is the most abundant peptide present in the mammalian nervous system and the finding that it elicits the most powerful orexigenic signal have led to active investigations of the properties of the NPY family of hormones, including peptide YY (PYY) and pancreatic polypeptide (PP). Nearly two decades of research have led to the identification of several NPY receptor subtypes and the development of useful receptor selective ligands. Moreover, these investigations have imp- cated NPY in the pathophysiology of a number of diseases, including feeding disorders, seizures, memory loss, anxiety, depression, and heart failure. Vigorous efforts are therefore continuing, not only to understand the bioche- cal aspects of NPY actions, but also toward developing NPY-based treatments for a variety of disorders. To facilitate these efforts, it was decided to produce the first handbook on NPY research techniques as part of the Methods in Molecular Biology Series. In compiling Neuropeptide Y Protocols, I have gathered contributions on techniques considered critical for the advancement of the NPY field from experts in various disciplines. Each chapter starts with a brief introduction, with Materials and Methods sections following. The latter sections are presented in an easy to follow step-by-step format. The last section of the chapter, Notes, highlights pitfalls and the maneuvers employed to overcome them. This information, not usually disseminated in standard research pub- cations, may prove extremely useful for investigators employing these te- niques in NYP research.
This book will take readers on a flying visit round the world, scouring the seven continents for the biggest, brightest and best birds on the planet. Urban Jungle creator Vicky Woodgate perfectly captures the brilliance of the bird world, each chapter taking us to a new continent and introducing birds from hummingbirds to hawks, and parrots to penguins. With a vintage travelogue feel, vibrant artwork and fascinating annotations, it is a book that will appeal to wildlife lovers from 7 to 70!
Parasitic nematodes (Nematoda) represent an important group of fish parasites. Many species are highly pathogenic, often causing serious diseases or even death to their fish hosts. The significance of recognizing these parasites increases with the development of aquaculture in many countries and with transcontinental transfers of fish. A prerequisite for developing effective control measures in fish culture is the exact identification of these parasites, as well as a knowledge of their, frequently complicated, host-parasite-environment relationships. The present monograph is the first to deal in detail with all nematodes which are parasites on European freshwater fish, providing contemporary knowledge of the taxonomy, biology and ecology of these parasites. This book is divided into introductory chapters, including general morphological, biological and ecological data on fish nematodes, their pathogenicity and methods of study; systematic part/species descriptions, data on hosts, localization, distribution and life cycles and bionomy of all species systematically arranged; and a host-nematode parasite list. This publication is intended for parasitologists, veterinarians, workers in fisheries, university students. It will also be of interest to ichthyologists, museum curators and those engaged in nature conservation.
Many of the papers in this volume were first presented at the Third International Great Apes of the World Conference, held July 3-6, 1998 in Kuching, Sarawak, Malaysia. The editors of this volume, the first in a two-volume series, are world renowned, having dedicated most of their lives to the study of great apes. The world's premiere primatologists, ethologists, and anthropologists present the most recent research on both captive and free-ranging African great apes. These scientists, through deep personal commitment and sacrifice, have expanded their knowledge of chimpanzees, bonobos, and gorillas. With forests disappearing, many of these studies will never be duplicated. This volume, and all in the Developments in Primatology book series, aim to broaden and deepen the understanding of this valuable cause.
Arid lands require that organisms inhabiting them be well-adapted to thrive or even just to survive. This book provides a review of the ecological adaptations - be they behavioural, physiological or morphological - of carnivores to arid environments. Following a general introduction into aridity and arid lands in Africa, the major carnivore families are presented. Ecological adaptations of carnivores in arid lands reveal the amplitude and resilience of the ecology of these animals. In setting up conservation measures, the nature and extent of such adaptations are important facets in determining the effective area and degree of heterogeneity required as habitat by a carnivore population so as to produce a viable unit.
One of the most striking and persistent ways humans dominate Earth is by changing land-cover as we settle a region. Much of our ecological understanding about this process comes from studies of birds, yet the existing literature is scattered, mostly decades old, and rarely synthesized or standardized. The twenty-seven contributions authored by leaders in the fields of avian and urban ecology present a unique summary of current research on birds in settled environments ranging from wildlands to exurban, rural to urban. Ecologists, land managers, wildlife managers, evolutionary ecologists, urban planners, landscape architects, and conservation biologists will find our information useful because we address the conservation and evolutionary implications of urban life from an ecological and planning perspective. Graduate students in these fields also will find the volume to be a useful summary and synthesis of current research, extant literature, and prescriptions for future work. All interested in human-driven land-cover changes will benefit from a perusal of this book because we present high altitude photographs of each study area.
The Preface to the first edition of this book explained the reasons for the publication of a comprehensive text on the rumen and rumen microbes in 1988. The microbes of the ruminant's forestomach and those in related organs in other animals and birds provide the means by which herbivorous animals can digest and obtain nutriment from vegetation. In turn, humans have relied, and still do rely, on herbivores for much of their food, clothing and motive power. Herbivores also form the food of carnivorous animals and birds in the wild. The importance of the rumen microorganisms is thus apparent. But, while a knowledge of rumen organisms is not strictly neces sary for the normal, practical feeding of farm animals, in recent years there has been much more emphasis on increasing the productivity of domesti cated animals and in rearing farm animals on unusual feedstuffs. Here, a knowledge of the reactions of the rumen flora, and the limits to these reactions, can be invaluable. In addition, anaerobic rumen-type microor ganisms are found in the intestines of omnivores, including humans, and can be implicated in diseases of humans and animals. They are also found in soils and natural waters, where they playa part in causing pollution and also in reducing it, while the same organisms confined in artificial systems are essential for the purification of sewage and other polluting and toxic wastes."
This is the first book to cover all aspects of Lagomorph biology. Lagomorphs are a mammalian order which includes rabbits, hares and pikas. They are distributed throughout the world and are of both scientific and public interest as they are classified between endangered and pest species. In addition, some have a high economic value as important game species. In the last few decades, a huge amount of information has been made available to the scientific community that has resulted in remarkable advances on all aspects of Lagomorph biology.
There is a marked and most unfortunate dichotomy in the studies of avian eggs and hence in the application of new findings in commerce. Thus over the past twenty years there has been a renewed interest in the contribu tions of various parts of an egg to embryo development. This is best illustrated by those studies that have explored the diffusion of respiratory gases across the shell and at long last have provided a fundamental definition of a previously nebulous term, porosity. The activity in this general area has led in the past four years to the publication of three major books dealing with many aspects of egg structure, function and embryogenesis. When brows ing over these books, two developments are evident. First, the advantages that are to be gained by comparative studies. Thus it is now common to see within a single book articles concerned with the eggs of a range of avian species as well as those of reptiles. Second, it is evident that zoologists and physiologists as well as those employed in large breeding firms are all contributing to an improvement of our knowledge of the egg's role in the breeding biology of birds. Comparative studies are a very uncommon feature of studies concerned with bacterial infection of eggs."
This volume presents the proceedings of Chemical Signals in Vertebrates 11, hosted by the University of Liverpool and held July 25 - 28, 2006 at the University of Chester in the United Kingdom. Chemical Signals in Vertebrates 11 contains the latest research on chemical communication relevant to vertebrates, particularly focusing on new research since the last meeting in 2003. Topics covered include chemical ecology, biochemistry, behavior and neurobiology of both the main olfactory and vomeronasal systems of vertebrates, from amphibia to mammals including humans. A broad range of taxonomic groups and topics are discussed, including sections on new directions in semiochemistry, olfactory response and function, recognition within species, sexual communication, maternal-offspring communication, communication between species, and applications for zoo animal enrichment and pest control.

This long-awaited third edition of A Complete Guide to the Snakes
of Southern Africa has been updated, revised and expanded. New
information based on scientific research relating to behaviour,
identification, reproduction and snake venoms has been included in the
species accounts.
The endothelial cells of the cerebral vasculature constitute, together with perivascular elements (astrocytes, pcricytes, basement membrane), the blood-brain barrier (BBB), which strictly limits and specifically controls the exchanges between the blood and the cerebral extracellular spacc.The existence of such a physical, enzymatic, and active barrier isolating the central nervous system has broad physiological, biological, pharmacological, and patho logical consequences, most of which are not yet fully elucidated. The Cerebral Vascular Biology conference (CVB '95) was organized and held at the "Carre des Sciences" in Paris on July I 0-12, 1995. Like the CVB '92 conference held in Duluth, Minnesota, three years ago, the objectives were to provide a forum for presentation of the most recent progresses and to stimulate discussions in the ticld of the biology, physiology. and pathology of the blood-brain barrier. The Paris conference gathered more than 50 participants. including investigators in basic neuroscience, physicians. and stu dents, who actively contributed to the scientific program by their oral or poster presentations. This volume contains a collection of short articles that summarize most of the new data that were presented at the conference. Six thematic parts focus on physiological transports. drug delivery, multidrug resistance P-glycoprotein, signal transduction at the BBB. interactions between the immune system and the cerebral endothelial cells, and the blood-brain barrier-related pathologies in the central nervous system. In addition, two introductory articles present new insights in the rapidly evolving topics of cerebral angiogenesis and gene transfer to the brain."
This spectacular new edition of the best-selling Helm field guide of all time covers all resident, migrant and vagrant species found in Kenya, Tanzania, Uganda, Rwanda and Burundi. More than 1,300 species are illustrated with full details of all the plumages and major races likely to be encountered. Concise text describes the identification, status, range, habits and voice, with fully updated range maps for each species. This authoritative book will not only be an indispensable guide to the visiting birder, but also a vital tool for those engaged in work to conserve and study the avifauna of the region - East Africa shelters a remarkable diversity of birds, many seriously endangered with small and vulnerable ranges.
More than 25 years ago, the first major review of primate communication appeared (Altmann, 1967). Since then, information on the communicative abilities of primates increased rapidly, resulting, 15 years later, in the appearance of the first volume in which signaling systems were analyzed in a broader variety of primate groups within an evolutionary perspective (Snowdon, Brown and Petersen, 1982). Seven years later, the first volume dedicated solely to primate vocal communication appeared (Todt, Goedeking and Symmes, 1988) and another four years later a volume followed in which nonverbal vocal communication in non-human primates and human infants was compared (Papousek, Jurgens and Papousek, 1992). None of these volumes, however, provided information about current technical advances in the field of bioacoustics, especially in digital sound analyzing systems, which offer primatologists, anthropologists and linguists nowadays a variety of rapid methods for analyzing human speech and non-human primate vocalizations in a quantitative and comparative way. Choosing the right method is difficult if a synopsis of these tools is lacking. Furthermore, information was particularly lacking on the natural signaling systems of two important primate groups, the prosimians and the apes. Likewise, new and unexpected insights into the ontogeny and evolution of vocal communication were gained during the past few years by the use of highly sophisticated sound analysis and statistical techniques.
