The Atlantic Walrus: Multidisciplinary insights into human-animal interactions addresses the key dimensions of long-term human walrus interactions across the Atlantic Arctic and subarctic regions, over the past millennia. This book brings together research from across the social and natural sciences to explore walrus biology, human culture, environmental conditions and their reciprocal effects. Together, 13 chapters of this book reconstruct the early evolution of walruses, walrus biology, the cultural significance and ecological impact of prehistoric and indigenous hunting practices, as well as the effects of commercial hunting and international trade. This book also examines historic and ongoing management strategies and, the importance of new research methodologies in revealing hitherto unknown details of the past, and concludes by discussing the future for Atlantic walruses in the face of climate change and increased human activities in the Arctic. This volume is an ideal resource for those who are seeking to understand an iconic Arctic species and its long and complex relationship with humans. This includes individuals and researchers with a personal or professional connection to walruses or the Arctic, as well as marine biologists, zoologists, conservationists, paleontologists, archaeologists, anthropologists, historians, indigenous communities, natural resource managers and government agencies.
Seemingly universal geometric forms unite the flow systems of engineering and nature. In this groundbreaking book, Adrian Bejan considers the design and optimization of engineered systems and discovers a relationship to the generation of geometric form in natural systems. The idea that shape and structure spring from the struggle for better performance in both engineering and nature is the basis of his new constructal theory: the objective and constraints principle in engineering is the same mechanism underlying the geometry in natural flow systems. From heat exchangers to river channels, Bejan draws many parallels between the engineered and natural worlds. Numerous illustrations, examples, and homework problems make this an ideal text for engineering design courses. Its provocative ideas will also appeal to a broad range of readers in engineering, natural sciences, economics, and business.
Phocid (or earless or true) seals are ecologically diverse, occupying habitats from the tropics to the poles in marine and freshwater and feeding on anything from tiny zooplankton to other marine mammals. There are 18 species of phocid seals, the smallest species (ringed seal) is more than 20 times smaller than the largest (southern elephant seal), with marked sexual dimorphism present in some species. This book examines the behavior, ecology, and physiology that allow phocid seals to inhabit such a wide range of habitats. The book is composed of 16 chapters written by 37 authors from 8 countries. The book first describes the general patterns of phocid behavior, followed by descriptions of what is known about well-studied species. We have taken a holistic approach, focusing not only on the behaviors themselves but also on the factors that constrain the expression of behavior and the proximate mechanisms driving behavior. In many cases, the chapters represent collaborations between well-established researchers and early-mid career individuals who bring new perspectives to help carry the field of phocid behavioral ecology well into the future.
A humorous look at what happens when taxidermy goes terribly wrong,
by the founder of the hit website crappytaxidermy.com.
This volume of the series Handbook of Zoology deals with the anatomy of the gastrointestinal digestive tract - stomach, small intestine, caecum and colon - in all eutherian orders and suborders. It presents compilations of anatomical studies, as well as an extensive list of references, which makes widely dispersed literature accessible. Introductory sections to orders and suborders give notice to biology, taxonomy, biogeography and food of the respective taxon. It is a characteristic of this book that different sections of the post-oesophageal tract are discussed separately from each other. Informations on form and function of organs of digestion in eutherians are discussed under comparative-anatomical aspects. The variability and diversity of anatomical structures represents the basis of functional differentiations.
Many complex traits define the human condition, including encephalization and bipedalism. The specific molecular signals and cellular processes producing these traits are the result of dramatic evolutionary change. At the same time, conservation of many of these developmental programs underlie both structure and function. Novel methodologies and techniques allow analysis of the collective behavior of cells, cell shapes, tissues, and organs. This volume demonstrates the essential role of cellular mechanisms in the evolutionary increase in the size and complexity of the primate brain. In addition, and concordant with encephalization, this book documents changes in the muscles and bones associated with the appearance of bipedalism. Genetic changes are the basis of these evolutionary changes, but transformation of genetic information into phenotypic outcomes occurs at the level of the cell, and this is the focus of the book. The goal is to encourage others to adopt evolutionary cell biology as a novel and necessary approach to the genotype-phenotype map of the diversification of primates, human variation, and human evolution. The contributors to this book utilize advances in genetic analysis, visualization of cells and tissues, and the merging of evolutionary developmental biology with evolutionary cell biology to address questions central to understanding the human and primate evolution. Key Features Explores mechanisms underlying trait distribution, dispersal, variation, and evolution through the direct testing of hypotheses especially with respect to patterns of encephalization, certain sensory modalities, and growth and life history specializations. Documents the advantages for anthropologists to work at the level of cells focusing on how genes provide instructions for cells to make structure and how environmental influences affect the behavior of cells. Illustrates the role cell biology plays with respect to encephalization, neocortical expansion, variation in facial morphology, locomotion, and dexterity. Describes novel methodologies and techniques allowing analysis of how the collective behavior of cells shapes tissues and organs. Related Titles Ripamonti, U., ed.

Many complex traits define the primate condition, including behaviors as fundamental as locomotion and traits as scrutinized as the dentition, and their study reveals dramatic evolutionary change across the primates. Genetic modifications are at the basis of these changes, but transformation of genetic information into phenotypes occurs at the level of the cell, which is the focus of this book. Contributors summarize novel methodologies to analyze the collective behavior of cells in forming tissues and organs influencing physiological functions and anatomical features that enable behaviors. Our goal is to review current knowledge and encourage others to adopt evolutionary cell biology to aid in deciphering the genotype-phenotype map that underlies the diversification of primates, human variation, and human evolution. The contributors to this book utilize advances in genetic analysis and visualization of cells and tissues and merge evolutionary developmental biology with evolutionary cell biology to address questions central to understanding human and primate evolution.

‘My collection of animals swelled to a point where even Mother occasionally grew alarmed’ The island of Corfu, where the Durrell family live in agreeable chaos, is paradise for aspiring naturalist Gerald. His battalion of creatures has grown to include eleven puppies, a toad named Dierdre and an unwelcome infestation of scorpions. Yet the human visitors to their sun-drenched villa are even more curious, whether it is an innocent pair of American painters ripe for practical jokes, or a supercilious Count who barely survives an outing on Gerald’s home-made boat, the Bootle-bumtrinket. The third volume in the Corfu Trilogy brings this glorious tale of halcyon days to a close.
This comprehensive volume provides a plethora of first-hand information on the diversity, biology, and ecology of edible marine bivalve molluscs. It covers the biology of edible marine bivalves; profiles about 180 species, providing information on their habitat, distribution, morphology, food and feeding, reproduction, conservation status, etc.; discusses their nutritional values; examines their pharmaceutical value; and looks at their diseases and parasites. This abundance of knowledge is presented in an easy-to-read style with informative illustrations. Marine bivalve molluscs play important roles in the marine ecosystems by filtering water and serving as habitat and prey for a variety of sea life. This diverse group of species, estimated at around 9,200, inhabits virtually the entire world's oceans, from the balmy tropics to the sub-zero Arctic, and from deep oceans to sandy and rocky shorelines. Among the marine bivalves, a total of 180 species (including mussels, oysters, scallops, cockles, and clams) have long been a part of the diet of coastal human populations. Many species of marine bivalves are also commercially important for other purposes, such as pearls and shells for jewelry and decoration. The volume, part of the Biology and Ecology of Marine Life book series, will be of great use to students and researchers in fisheries science, marine biology, aquatic biology, and zoology.

Note: T&F does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka.
This contributory volume is a comprehensive collection on the mangrove forest eco-system and its ecology, the resources and potentials of mangroves, conservation efforts, mangrove eco-system services and threats to conservation. The book is an all-inclusive compilation on the status, conservation and future of mangroves. Mangroves are a unique ecosystem providing several ecosystem services. They are formed in the inter-tidal areas of large rivers and coastal islands. Mangroves thrives due to constant interaction with the terrestrial and marine ecosystem. These are the species dynamics, varying tidal amplitudes, plant succession, changing floral pattern of the channels of the estuary, the varying sediment transportation. There was 20% decline in mangrove forest area in the last 25 years due mainly to conversion and coastal development. Lengthy recovery periods required for the degraded mangrove forests. Hence there is an urgent need to take stock of the updated information on these mangroves at global level. It is of immense value to scientific community involved in teaching, research and extension activities related to mangrove conservation.
An exploration of the various ways animals and their relations to humans have been depicted throughout the ages. This volume delves into the realm between representative images and real animals. It is a historical inquiry into human interaction with the animals we eat, pamper, experiment on, and imagine, as they have been variously domesticated, slaughtered, loved, studied, and made into icons of human invention. Common assumptions and experiences with animals have entered into the functioning and conceptualizing of life, yet these are historically and culturally contingent. The essays in this volume unveil the ways in which human-animal relationships reveal the interhuman structures of the cultures in which they are formed. By using animals as a lens, they refocus our awareness of the ways in which humans have allotted resources, gathered knowledge, and structured families. The treatment of animals is often a guide to the treatment of people within a society, while the perceived 'stewardship' of humans over animals has helped shape the broader environment that both human and nonhuman animals share. The authors tackle their subject from a variety of levels -- popular, scientific, and economic. The essays explore the vast borderland between human ideas and physical nature regarding animal representation. Contributors include Richard W. Burkhardt, Jr., Jonathan Burt, Ken C. Erickson, Katherine C. Grier, Richard C. Hoffmann, Andrew C. Isenberg, JacquelineMilliet, John Solomon Otto, Karen A. Rader, Harriet Ritvo, Nigel Rothfels, Kenneth J. Shapiro, and Edward I. Steinhart. Mary Henninger-Voss is an Associate of the Shelby Cullom Davis Center for Historical Studies, Princeton University.
The 26 recognized minor phyla comprise aberrant clades, as most of them terminate as blind offshoots. Untied from the discussion on their phylogenesis of minor phyla, this book is largely devoted, for the first time, to aspects of reproduction and development in minor phyletics. The minor phyla are not as speciose (1,795 species/phylum) as the major phyla (157,066 species/phylum) are. The accumulation of deleterious genes causes inbreeding depression among progenies arising from parthenogenesis, clonal multiplication and selfing hermaphrodites. The reason for the limited species diversity in minor phyla is traced to (i) eutelism in 65.7% of minor phyletics and (ii) existence of 21.6% clonals, (iii) 6.4% parthenogens and (iv) 1.2% selfing hermaphroditism. Gonochorism obligately requires motility to search for a mate. The combination of low motility and gonochorism from Placozoa to hemocoelomatic minor phyla has limited diversity to < 1,000 species. Over 19% of minor phyletics are hermaphrodites. With the need to manifest and maintain dual sexuality, fecundity of hermaphrodites may be reduced to 50% of that in gonochores. Adopting an array of strategies, < 100 hermaphrodites are selfers. In eutelics, mitotic division is ceased in somatic cells after hatching. For the first time, the prevalence of eutelism has been brought to light in numbers of all the six pseudocoelomate phyla and priapulids. Eutelism limits fecundity to 30-300 eggs in free-living pseudocoelomates, priapulids and possibly other hemocoelomates. In them, sperm production is less than that of egg production; as a result, a large fraction of their eggs is sterile. With a high proportion of non-eutelic gametic cells (35%), Nematoda and possibly Nematomorpha and Acanthocephala are more fecund than rotifers, in which the proportion is 15%. Briefly, the reasons for the limited species diversity in minor phyletics are traced to eutelism, parthenogenesis and clonal multiplication. Surprisingly, parthenogenesis and clonal multiplication mutually eliminate each other. This is also true of hermaphroditism and parthenogenesis. However, clonal multiplication is prevalent from structurally simplest Placozoa to the most complex Ascidiacea, except in pseudocoelomates and hemocoelomates. A limited number of cells and cell types, and the consequent structural simplicity facilitate manifestation of parthenogenesis in pseudocoelomates and parasitism in Mesozoa, Myxozoa, 59% of Nematoda, Nematomorpha, Acanthocephala and Pentastomida. Despite hermaphroditism, Bryozoa (5,700 species) and Ascidiacea (3,000 species) are speciose among minor phyla. For the first time, the importance of fusion of fragments or colonies - an event equivalent to gamete fusion at fertilization - is recognized as a source of new gene combination. Besides, the colonies in these minor phyla degenerate and regenerate more or less regularly. Only the fittest degenerated colonies may be rejuvenated and regenerated.
A persistent argument among evolutionary biologists and philosophers revolves around the nature of natural selection. Evolution by Natural Selection: Confidence, Evidence and the Gap explores this argument by using a theory of persistence as an intentional foil to examine ways in which similar theories can be misunderstood. It discusses Charles Darwin's theory of natural selection, including what the theory says, what it aims to explain, and how it manages to explain natural selection. Darwin's theory is so familiar today that it feels universally understood. However, the fact that there are so divergent views about the theory means that not everyone who thinks he or she understands it can be right. This book describes the history of evolutionary theory as a sequence of theoretical developments, not all of which can be considered improvements. In particular, it suggests that some attempts to use the theory of natural selection end up reshaping the concepts involved so that they can be applied more easily to the world. As a result, the theory is stripped of some of its explanatory power and becomes detached from the empiricism that good scientific examination requires. With these issues in mind, Evolution by Natural Selection shows there are aspects of the theory of natural selection that are not totally understood. These misunderstandings create problems in uses of the theory. At a time when selectionist explanations are being brought forward to explain an ever-widening range of phenomena, this book analyzes the explanatory structure of Darwin's theory. It takes a much-needed thoughtful look into the working parts of the theory of natural selection to provide better understanding of the theory and its role in contemporary science and life.
The value of the canine nose is well-documented, and working dogs are being utilized for their olfactory skills in an increasing number of fields. Not only are dogs used by police, security, and the military, but they are also now used in forensic science, in medical detection of disease, in calculating population trends of endangered species and eradicating invasive species in protected environments, and in identifying infestations and chemical contaminants. Edited and contributed to by eminent scholars, Canine Olfaction Science and Law: Advances in Forensic Science, Medicine, Conservation, and Environmental Remediation takes a systematic scientific approach to canine olfaction. It includes work from scientists working in pure and applied disciplines, trainers and handlers who have trained and deployed detection dogs, and lawyers who have evaluated evidence produced with the aid of detection and scent identification dogs. The book is divided into six sections covering The anatomy, genetics, neurology, and evolution of canine olfaction as well as diseases affecting it The chemistry and aerodynamics of odors Behavior, learning, and training Uses of canine olfaction in forensics and law Uses in conservation and remediation Uses in detection of diseases and medical conditions The various contributors describe cutting edge research, some conclusions of which are the subject of vigorous debates between various laboratories and researchers. The editors have added cross-references so that readers can consider the different perspectives that are currently being advanced and understand where consensus is being built and where more research needs to be done. A useful practical reference, Canine Olfaction Science and Law provides a wealth of information beneficial to a wide range of disciplines. It aids trainers and handlers of detection dogs as well as various professionals in healthcare, law enforcement, forensic science, and environmental conservation to gain a better understanding of the remarkable power of the canine nose while encouraging further advances in applications.
Parrotfish are found on almost every coral reef in the world. This ubiquity and uniqueness of their feeding action make them one of the most important groups of fishes within coral reef ecosystems. But why, exactly, are parrotfish so important to reefs? Can the evolution of a particular jaw morphology and feeding action really have had such a large impact on the health and functioning of the world's coral reefs? This book introduces the reader to this fascinating group of fishes (Labridae, Scarinae), from the morphological innovation of a jaw that has the power to bite through solid calcium carbonate, to the threats currently faced by parrotfish populations around the world. It contains new insights into their diet and food processing ability, and lifehistories, and concludes with an overview of emerging and future research directions.
The Handbook of Australasian Biogeography is the most comprehensive overview of the biogeography of Australasian plants, fungi and animal taxa in a single volume. This volume is unique in its coverage of marine, freshwater, terrestrial, and subterranean taxa. It is an essential publication for anyone studying or researching Australasian biogeography. The book contains biogeographic reviews of all major plant, animal and fungal groups in Australasia by experts in the field, including a strong emphasis on invertebrates, algae, fungi and subterranean taxa. It discusses how Australasia is different from the rest of the world and what other areas share its history and biota.
This book critically investigates the pervasiveness of anthropomorphised animals in popular culture. Anthropomorphism in popular visual media has long been denounced for being unsophisticated or emotionally manipulative. It is often criticised for over-expressing similarities between humans and other animals. This book focuses on everyday encounters with visual representations of anthropomorphised animals and considers how attributing other animals with humanlike qualities speaks to a complex set of power relations. Through a series of case studies, it explores how anthropomorphism is produced and circulated and proposes that it can serve to create both misunderstandings and empathetic connections between humans and other animals. This book will appeal to academics and students interested in visual media, animal studies, sociology and cultural studies.
Biogeography and Evolution in New Zealand provides the first in-depth treatment of the biogeography of New Zealand, a region that has been a place of long-enduring interest to ecologists, evolutionary scientists, geographers, geologists, and scientists in related disciplines. It serves as a key addition to the contemporary discussion on regionalization-how is New Zealand different from the rest of the world? With what other areas does it share its geology, history, and biota? Do new molecular phylogenies show that New Zealand may be seen as a biological 'parallel universe' within global evolution?
When a bone of unknown origin is found at a location, forensic implications arise immediately. Is this bone human, and if so, is it evidence of a murder? Human and Non-Human Bone Identification: A Color Atlas presents a comprehensive handbook of photographs and other information essential for law enforcement and forensic anthropologists when examining skeletal remains and determining species and body parts. Presenting over 3000 color photographs, this atlas is a practical comparative guide to the differences among species for nearly all bones in the body. Useful in either the laboratory or the field, it features images of the types of bones that are most commonly discovered, and provides annotations pointing out salient features. The book begins with a section on general osteology and explains the major anatomical differences between humans and other animals. It compares human and non-human bones, categorized by type of bone, and includes most of the major bones in humans and non-humans. The third section discusses non-human skeletal elements, categorized by species, and explores numerous skeletal elements within those species. This book is also available on a fully searchable DVD: Catalog no. 62964 Includes Bones from the Following Species! Moose Elk Deer Bison Cow Antelope Mountain Sheep Domestic Sheep Llama Horse Bear Wolf Coyote Domestic dog Mountain lion Bobcat Raccoon Badger Skunk River Otter Beaver Porcupine Marmot Prairie dog Rabbit Norway rat Squirrel Armadillo Opossum Vampire bat Seal Written by Diane L. France, one of the most respected forensic anthropologists in the world, this supremely organized atlas helps those tasked with bone identification to quickly and efficiently determine the origin of discovered remains and plan the appropriate course of action.
