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."

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.

Birds are intelligent, sociable creatures that exhibit a wide array of behaviours - from mobbing and mimicking to mating and joint nesting. Why do they behave as they do? Bringing to light the remarkable actions of birds through examples from species around the world, How To Read a Bird presents engaging vignettes about the private lives of birds, all explained in an evolutionary context. Richly illustrated, this book explores the increasing focus on how individual birds differ in personality and how big data and citizen scientists are helping to add to what we know about them.

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."

The most comprehensive book about Florida's marine fishes ever produced, Marine Fishes of Florida includes hundreds of photographs and descriptions of species you'll encounter-plus many that are rare-when diving, snorkeling, kayaking, or fishing. Coverage includes both the Atlantic and Gulf coastline, from habitats near the shore to deeper waters. Fishes found in coastal rivers and other brackish waters are fully represented, as are offshore species that venture into Florida's waters often enough to be called "occasional visitors." David B. Snyder and George H. Burgess intertwine personal observations with results from research studies to provide accurate-often surprising-details. The result is a set of beautifully succinct identification descriptions coupled with information about each species' natural history. From the largest sharks to the smallest cryptic gobies, from homely toadfishes to the spectacularly colored reef fishes, this book is certain to help you better understand the fish you've seen or hooked. Features of Marine Fishes of Florida include * Color photographs by leading marine photographers* Differentiation of adult and juvenile forms* Coverage of 133 fish families and hundreds of species* Size and geographical range data* Natural history and conservation notes* Explanations of geologic history and current habitats

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.

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.

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."

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.

Conservation Physiology for the Anthropocene: A Systems Approach, Volume 39A in the Fish Physiology series, is a comprehensive synthesis on the physiology of fish in the Anthropocene. This volume closes the knowledge gap by considering the many ways in which different physiological systems (e.g., sensory physiology, endocrine, cardio-respiratory, bioenergetics, water and ionic balance and homeostasis, locomotion/biomechanics, gene function) and physiological diversity are relevant to management and conservation. As the world is changing, with a dire need to identify solutions to the many environmental problems facing wild fish populations, this book comprehensively covers conservation physiology and its future techniques. Conservation physiology reveals the many ways in which environmental change and human activities can negatively influence wild fish populations. These tactics inform new management and conservation activities and help create the necessary conditions for fish to thrive.

The ovary is a suitable organ for studying the processes of cell death. Cell death was first described in the rabbit ovary (Graaffian follicles), the phenomenon being called 'chromatolysis'. To date, it is recognized that various forms of cell death (programmed cell death, apoptosis and autophagy) are essential components of ovarian development and function. Programmed cell death is responsable for the ovarian endowment of primordial follicles around birth; in the prepuberal and adult period, apoptosis is a basic mechanism by which oocytes are eliminated by cancer therapies and environmental toxicants; in the ovarian cycle, follicular atresia and luteal regression involve follicular cell apoptosis. Finally, abnormalities in cell death processes may lead to ovarian disease such as cancer and chemoresistance. In this book, after an introductory description of various forms of cell death and of the ovary development and function in mammals, the processes of cell death in ovarian somatic cells and oocytes are described at cytological, physiological and molecular levels and analyzed in the embryonic, prepuberal and adult ovary. A complex array of molecular pathways triggered by extrinsic and intrinsic signals able tor induce or suppress cell death in the same cell, according to cell type and ovary developmental stage, emerges. Physiological interactions with the axis hypothalamus-hypophysis as well as ovarian internal functional signal are also critically reviewed to explain the abortive development of follicles before the beginning of the ovarian cycle. The book conveys information useful to the updating of biologists and physicians who are interested to the ovary biology and functions. Hopefully it should provide also clues for stimulating novel experiments in the study of cell death in the mammalian ovary still at an early stage.

In the 1960s, it was believed that no more than about 4,000 orang-utans remained in the wild. Consequently, IUCN - The World Conservation Union - declared the ape an endangered species, demanding its world-wide protection. Nevertheless, the orang-utan today faces extinction because it is dependent on a rain-forest habitat that is rapidly being demolished due to human greed, and a growing human population. Rijksen was among the first to make a detailed study of the ape in the wild, emerging as an authority on orang-utan conservation. In the late 1980s he became so alarmed by local rumours of the rapid decline of wild orang-utans that he initiated the study leading to this book. Meijaard conducted the ambitious, island-spanning surveys in Borneo and Sumatra to reveal the ape's whereabouts. This is the story of their findings. It is the first comprehensive study of the ape's distribution and status based on a wealth of first-hand field data, and a frank, disturbing account of a mixture of good intentions, ignorance and greed, spelling doom for our Asian relative. Nevertheless, the authors emphasise that the orang-utan can survive. A realistic plan to save the ape, and with it thousands of unique wild animals and plants, does exist. It is the authors' hope that Our Vanishing Relative, so urgent and eloquent in its description of the deadly net of problems descending over our helpless relative, will awaken attention and empathy in order to safeguard the future of the orang-utan.

The Chilton Conference on Inositol and Phosphoinositides, held on January 9-11, 1984 at Southwestern Medical School, University of Texas Health Science Center, Dallas, Texas, was the third in a series of conferences on cyclitols and phosphoinositides. The first took place in 1968 in New York [Ann. New York Acad. Sci. (1969), 765,508-819] and the second was held in 1977 in East Lansing, Michigan [eyclitols and Phosphoinositides, Wells, W. W. and Eisenberg, F. , eds. , (1978) Academic press, New York, pp. 1-607. ] In the interim since the previous conference, not only has the pace of research in the field accelerated markedly, but the physiological importance of phosphoinositide metabolism has become apparent to an increasing number of investigators from diverse fields in the life sciences. Thus it seemed to us timely for both recent and established workers in this area, as well as others whose interests impinged on it, to meet in order to disseminate new information, to review, and perhaps arrive at, a consensus of our current understanding of the role of inositol and phosphoinositides, and to establish new directions for research for the next few years. The expansion of the field since the last meeting made it mandatory to restrict the scope of the topics covered at the conference, primarily to aspects dealing with mammalian systems. We sincerely regretted the exclusion of recent research on cyclitols and phosphoinositides in microbes and plants and hope that these areas will be included in future conferences.
