Hominin Postcranial Remains from Sterkfontein, South Africa, 1936-1995 (Human Evolution Series)

by Bernhard Zipfel, Brian G. Richmond, and Carol V. Ward

The 1924 African discovery of an early hominin child's skull, referred to as Australopithecus africanus by Raymond Dart, was a major event in the history of paleoanthropology. This provided the first evidence of early hominins in Africa and overturned conventional ideas about human evolution. Subsequent discoveries of A. africanus fossils, notably from cave deposits at Sterkfontein, yielded the first evidence that early hominins were habitual bipeds. Fifty years after this, the discovered wealth of fossil evidence in eastern Africa of the slightly older and craniodentally more primitive taxon, A. afarensis, catalyzed debates about the origin and evolution of human gait and the phylogentic relationships among early hominins. This formed the main basis of our understanding of early hominin bipedality and paleobiology. Little attention has been paid to the variation among species in postcranial anatomy and locomotion, although intriguing hints are beginning to appear in the literature. Did multiple varieties of bipedality evolve? Did australopith species differ in positional or manipulative abilities, body proportions, or patterns of sexual dimorphism? These are critical questions for understanding the evolution of australopiths and hominin locomotion. In this book, Bernhard Zipfel, Brian Richmond, Carol Ward, and the most knowledgeable scholars in their respective fields provide groundbreaking accounts for each postcranial fossil and expert examinations into the background of each fossil. The chapters include standardized high-quality photographs and anatomical descriptions to allow readers to read the book entirely or learn by comparing features across chapters. Hominin Postcranial Remains from Sterkfontein, South Africa, 1936-1995 is an evolutionary history of South African hominins, and it offers readers an orientation and introduction to the field. This is an important reference book for professional paleontologists, paleobiologists, anthropologists, geologists, students, and historians interested in human evolution.

Blue Dog

by Louis De Bernieres

'The kind of book that changes readers for the better' GuardianWhen a family tragedy means Mick is sent to the outback to live with his Granpa, it looks as if he has a lonely life ahead of him. The cattle station is a tough place for a child, where nature is brutal and the men must work hard in the heat and dust. However, after a cyclone hits, things change for Mick. Exploring the floodwaters, he finds a lost puppy covered in mud and half-drowned. Mick and his dog immediately become inseparable as they take on the adventures offered by their unusual home, and the business of growing up, together. In this charming prequel to the much-loved Red Dog, Louis de Bernières tells the moving story of a young boy and his Granpa, and the charismatic and entertaining dog who so many readers hold close to their hearts.

Acarid Phylogeny and Evolution: Proceedings of the IV Symposium of the European Association of Acarologists

by Fabio Bernini Roberto Nannelli Giorgio Nuzzaci Enrico De Lillo

The words pronounced by Serge Kreiter during the meeting come to mind. They could record exactly the situation of Acarology in Europe and in the World: "I think that in many European countries there are very few full time acarologists. It is very rare to have new positions available . . . . And public money, from the European Community but also from national countries, is very hard to get when you want to work on mites . . . . Could two acarological associations in Europe (Eur. A. Ac. and S. I. A. L. F) work together or, better, get married?" So, the fourth symposium of the European Acarologists has not only been the occasion to have an idea on which direction the research is addressed today, but also it pointed out the difficulties of our "scientific hranch". On the basis of the presentations and invited papers we had evidences of a "new" Acarology based on modern techniques and methods of investigations but also the importance, often sheltered even if of relevant value, of the "old" Acarology made on the alpha taxonomy and basic studies. So, a "new" Acarology needs the "old" one. In this context, the hope to put together the European acarologists has been coming up. This fact, of political meaning, can surely improve the acarological movement and the discussion on this point showed clearly the importance of several other activities and efforts in this direction. We hope that the meeting in Siena will represent a significative stone for the progress of Acarology.

Zoogeography of Arachnida (Monographiae Biologicae #94)

by Petar Beron

This volume merges all geographical and paleogeographical data on all groups of the arachnofauna. The book features topics such as the ecological factors, climate and other barriers that influence the distribution of arachnida. It also elaborates on the characteristics of the distribution such as arachnida at high altitude (e.g. Himalaya), in caves, in polar regions and highlights differences between the arachnofauna of e.g. Mediterranean regions vs Central Europe, West African vs Indomalayan and more. Furthermore, amongst other topics the volume also includes chapters on the systems of arachnida, fossil orders, dispersal and dispersion, endemics and relicts, regional arachnogeography, cave and high altitude arachnida.

Freshwater Fish Distribution (American Politics And Political Economy Ser.)

by Tim M. Berra

With more than 29,000 species, fishes are the most diverse group of vertebrates on the planet. Of that number, more than 12,000 species are found in freshwater ecosystems, which occupy less than 1 percent of the Earth’s surface and contain only 2.4 percent of plant and animal species. But, on a hectare-for-hectare basis, freshwater ecosystems are richer in species than more extensive terrestrial and marine habitats. Examination of the distribution patterns of fishes in these fresh waters reveals much about continental movements and climate changes and has long been critical to biogeographical studies and research in ecology and evolution. Tim Berra’s seminal resource, Freshwater Fish Distribution,maps the 169 fish families that swim in fresh water around the world. Each family account includes the class, subclass, and order; a pronunciation guide to the family name; life cycle information; and interesting natural history facts. Each account is illustrated, many with historical nineteenth-century woodcuts. Now available in paperback, this heavily cited work in ichthyology and biogeography will serve as a reference for students, a research support for professors, and a helpful guide to tropical fish hobbyists and anglers.

Skeletal Musculature in Larval Phases of the Beetle Epicauta Segmenta (Series Entomologica #16)

by A. Berrios-Ortiz R.B. Selander

This study, the first in an intended series of anatomical investigations of the blister beetles, was undertaken primarily for the purpose of determining the changes that occur in the skeletal musculature during postembryonic larval development. The species studied, Epicauta segmenta (Say), like others belong­ ing to the coleopterous family Meloidae, is characterized by hypermetamor­ phosis (SELANDER and WEDDLE, 1969). The egg develops into an active, well sclerotized larva that searches for grasshopper eggs, which, as in the case of all species of Epicauta, serve as the sole larval food. This triungulin phase of the larval stage, as it is called, is followed by the first grub phase (Fig. 1), during which the larva continues to feed and undergoes several molts. After feeding is completed the larva commonly enters a sessile, diapausing coarctate phase in which the integument is heavily sclerotized and the appendages, including the legs, are vestigial (Fig. 2). Following this the larva attains an active second grub phase (Fig. 3) closely resembling the first grub phase in external anatomy. Normally, the second grub phase leads directly to pupation and the formation of the adult. An alternate, abbreviated developmental pattern, involving pupation immediately after the first grub phase, is also recorded in this and many other species of Epicauta.

Scale insects feed on plant juices and can easily be transported to new countries on live plants. They sometimes become invasive pests, costing billions of dollars in damage to crops worldwide annually, and farmers try to control them with toxic pesticides, risking environmental damage. Fortunately, scale insects are highly susceptible to control by natural enemies so biological control is possible. They have unique genetic systems, unusual metamorphosis, a broad spectrum of essential symbionts, and some are sources of commercial products like red dyes, shellac and wax. There is, therefore, wide interest in these unusual, destructive, beneficial, and abundant insects. The Encyclopedia of Scale Insect Pests is the most comprehensive work on worldwide scale insect pests, providing detailed coverage of the most important species (230 species in 26 families, 36% of the scale insect pest species known). Advice is provided on collection, preservation, slide-mounting, vouchering, and labelling of specimens, fully illustrated with colour photographs, diagrams and drawings. Pest species are presented in two informal groups of families, the 'primitive' Archaeococcoids followed by the more 'advanced' Neococcoids, covered in phylogenetic order. Each family is illustrated and diagnosed based on features of live and slide-mounted specimens, with information on numbers of genera and species, main hosts, distribution, and biology. For the important pest species, coverage includes information on the morphology of live and slide-mounted specimens, common names, principal synonyms, geographical distribution, plant hosts, plant damage and economic impact, reproductive biology, dispersal, and management strategies including biological, cultural and chemical control, sterile insect techniques, regulatory control, early warning systems and field monitoring. An additional complete list of scale insect pests worldwide is provided, comprising 642 species in 28 scale insect families (about 8% of the 8373 species of living scales known), with information on plant hosts, geographical distribution and validation sources. Beneficial uses of scale insects include sources of red dyes, natural resins and waxes, and agents for invasive weed control, alongside the importance of their honeydew to bees for making honey, and as a food source to other animals. Academic researchers, students, entomologists, pest management officials in agribusiness or government including plant quarantine identifiers, extensionists, farmers, field scientists and ecologists will all benefit from this book.

The Hepatocyte Review

by M. N. Berry Anthony M. Edwards

It is thirty years since the technique of high-yield preparation of isolated hepatocytes, by collagenase perfusion of the liver, was published. The original method described by Berry and Friend has undergone many minor modifications by other workers, and the two-step procedure introduced by Seglen in 1976 has become the most frequent way to prepare hepatocyte suspensions. An important development introduced by Bissell in 1973 was the use of the cells as the first step in monolayer culture. The availability of the isolated hepatocyte preparation as cells in suspension or culture has undoubtedly facilitated research on the liver. This was emphasised in our book, published (with Dr. Greg Barritt) in 1990, which described in detail methods of preparation and the properties of the isolated hepatocytes. It also discussed the usefulness of the preparation for the study of intermediary and xenobiotic metabolism, calcium ion transport, and the growth and differentiation of hepatocytes in culture. The book also touched briefly on a range of specialised techniques, including peri fusion, subcellular fractionation, transplantation, cryopreservation and measurement of intracellular pH. Although standard procedures for the manipulation of hepatocytes have not changed a great deal in ten years, they have undoubtedly been refined. This applies particularly to hepatocyte culture techniques, cryopreservation, and even to preparation of hepatocyte suspensions, where it is now feasible to use purified enzymes. There is also much more emphasis on the use and study of human hepatocytes, particularly in the field of pharmacology and therapeutics.

Population Cycles: The Case for Trophic Interactions

by Alan Berryman

For over sixty years, understanding the causes of multiannual cycles in animal populations has been a central issue in ecology. This book brings together ten of the leaders in this field to examine the major hypotheses and recent evidence in the field, and to establish that trophic interactions are an important factor in driving at least some of the major regular oscillations in animal populations that have long puzzled ecologists.

Dynamics of Forest Insect Populations: Patterns, Causes, Implications (Population Ecology)

by Alan A. Berryman

Insects multiply. Destruction reigns. There is dismay, followed by outcry, and demands to Authority. Authority remembers its experts or appoints some: they ought to know. The experts advise a Cure. The Cure can be almost anything: holy water from Mecca, a Government Commis­ sion, a culture of bacteria, poison, prayers denunciatory or tactful, a new god, a trap, a Pied Piper. The Cures have only one thing in common: with a little patience they always work. They have never been known entirely to fail. Likewise they have never been known to prevent the next outbreak. For the cycle of abundance and scarcity has a rhythm of its own, and the Cures are applied just when the plague of insects is going to abate through its own loss of momentum. -Abridged, with insects in place of voles, from C. Elton, 1924, Voles, Mice and Lemmings, with permission of Oxford University Press This book is an enquiry into the "natural rhythms" of insect abundance in forested ecosystems and into the forces that give rise to these rhythms. Forests form unique environ­ ments for such studies because one can find them growing under relatively natural (pri­ meval) conditions as well as under the domination of human actions. Also, the slow growth and turnover rates of forested ecosystems enable us to investigate insect popula­ tion dynamics in a plant environment that remains relatively constant or changes only slowly, this in contrast to agricultural systems, where change is often drastic and frequent.

Forest Insects: Principles and Practice of Population Management (Population Ecology)

by Alan A. Berryman

This book is intended as a general text for undergraduates studying the manage­ ment of forest insect pests. It is divided into four parts: insects, ecology, manage­ ment, and practice. Part I, Insects, contains two chapters. The first is intended to provide an overview of the general attributes of insects. Recognizing that it is impossible to adequately treat such a diverse and complex group of organisms in such a short space, I have attempted to highlight those insectan characteristics that make them difficult animals to combat. I have also tried to expose the insects' weak points, those attributes that make them vulnerable to manipulation by human actions. Even so, this first chapter will seem inadequate and sketchy to many of my colleagues. Ideally, this book should be used in conjunction with a laboratory manual covering insect anatomy, physiology, biology, behavior, and classifica­ tion in much greater depth-in fact, this is how I organize my forest entomology course. It is hoped that this first chapter will provide nonentomologists with a general feel for the insects and with a broad understanding of their strengths and weaknesses, while Chapter 2 will provide a brief overview of the diverse insect fauna that attacks the various parts of forest trees and their products.

Population Systems: A General Introduction

by Alan A. Berryman Pavel Kindlmann

This unique book is concerned with the general principles and theories of population ecology, based on the idea that the rules governing the dynamics of populations are relatively simple, and that the rich behavior we observe in nature is a consequence of the structure of the system rather than of the complexity of the underlying rules. From this perspective, the dynamic behavior of single-species populations is examined and an elementary feedback model of the population system is developed. This single-species model is refined and generalized by examining the mechanisms of population regulation.

Cytoskeleton (Cellular Organelles)

by A.D. Bershadsky J.M. Vasiliev

This book, like other monographs of the Cellular Organelles series, is not a comprehensive review, but an introduction to the study of cytoskeleton. Accordingly, we describe only the main facts and concepts related to cyto­ skeleton. Needless to say, selection and interpretation was influenced by the personal interests and opinions of the authors, although we attempted to be as fair as possible. We wished to familiarize the reader not only with well­ established facts, but with current unsolved problems. Therefore, the words "possibly," "maybe," "not known," and "not clear" are much more frequent in this text than in many others. In accordance with the style of the series, relatively short lists of addi­ tional readings are given at the end of each chapter; these lists contain mostly the recent reviews and a few original papers describing certain phenomena in detail. Few references are cited in the text; these citations are given to help the reader find the source of certain new data and theories, which are not discussed at length in the reviews. In contrast, many well-established facts and widely known theories are not cited.

Whales, Dolphins, and Porpoises: A Natural History and Species Guide

by Annalisa Berta

The eighty-nine cetacean species that swim our seas and rivers are as diverse as they are intelligent and elusive, from the hundred-foot-long, two-hundred-ton blue whale to the lesser-known tucuxi, ginkgo-toothed beaked whale, and diminutive, critically endangered vaquita. The huge distances these highly migratory creatures cover and the depths they dive mean we catch only the merest glimpses of their lives as they break the surface of the water. But thanks to the marriage of science and technology, we are now beginning to understand their anatomy, complex social structures, extraordinary communication abilities, and behavioral patterns. In this beautifully illustrated guide, renowned marine mammalogist Annalisa Berta draws on the contributions of a pod of fellow whale biologists to present the most comprehensive, authoritative overview ever published of these remarkable aquatic mammals. Opening with an accessible rundown of cetacean biology—including the most recent science on feeding, mating, and communication—Whales, Dolphins, and Porpoises then presents species-specific natural history on a range of topics, from anatomy and diet to distribution and conservation status. Each entry also includes original drawings of the species and its key identifiers, such as fin shape and color, tooth shape, and characteristic markings as they would appear both above and below water—a feature unique to this book. Figures of myth and—as the debate over hunting rages on—figures of conflict since long before the days of Moby-Dick, whales, dolphins, and porpoises are also ecologically important and, in many cases, threatened. Written for general enthusiasts, emergent cetacean fans, and biologists alike, this stunning, urgently needed book will serve as the definitive guide for years to come.
