From one of the world's leading authorities on animal behavior, the astonishing story of how the brain drives the evolution of beauty in animals and humans In A Taste for the Beautiful, Michael Ryan, one of the world's leading authorities on animal behavior, tells the remarkable story of how he and other scientists have taken up where Darwin left off, transforming our understanding of sexual selection and shedding new light on animal and human behavior. Drawing on cutting-edge science, Ryan explores key questions: Why do animals perceive certain traits as beautiful and others not? Do animals have an inherent sexual aesthetic and, if so, where is it rooted? Ryan argues that the answers lie in the brain-particularly of females, who act as biological puppeteers, spurring the development of beautiful traits in males. Vividly written and filled with fascinating stories, A Taste for the Beautiful will change how you think about beauty and attraction in the animal world and beyond.

Beavers are widely recognised as a keystone species which play a pivotal role in riparian ecology. Their tree felling and dam building behaviours coupled with a suite of other activities create a wealth of living opportunities that are exploited by a range of other species. Numerous scientific studies demonstrate that beaver-generated living environments that are much richer in terms of both biodiversity and biomass than wetland environments from which they are absent. Emerging contemporary studies indicate clearly that the landscapes they create can afford sustainable, cost-effective remedies for water retention, flood alleviation, silt and chemical capture. Beaver activities, especially in highly modified environments, may be challenging to certain land use activities and landowners. Many trialled and tested methods to mitigate against these impacts, including a wide range of non-lethal management techniques, are regularly implemented across Europe and North America. Many of these techniques will be new to people, especially in areas where beavers are newly re-establishing. This handbook serves to discuss both the benefits and challenges in living with this species, and collates the wide range of techniques that can be implemented to mitigate any negative impacts. The authors of this handbook are all beaver experts and together they have a broad range of scientific knowledge and practical experience regarding the ecology, captive husbandry, veterinary science, pathology, reintroduction and management of beavers in both continental Europe and Britain.

Reconstructing the paleobiology of fossil non-human primates, this book is intended as an exposition of non-human primate evolution that includes information about evolutionary theory and processes, paleobiology, paleoenvironment, how fossils are formed, how fossils illustrate evolutionary processes, the reconstruction of life from fossils, the formation of the primate fossil record, functional anatomy, and the genetic bases of anatomy. Throughout, the emphasis of the book is on the biology of fossil primates, not their taxonomic classification or systematics, or formal species descriptions. The author draws detailed pictures of the paleoenvironment of fossil primates, including contemporary animals and plants, and ancient primate communities, emphasizing our ability to reconstruct lifeways from fragmentary bones and teeth, using functional anatomy, stable isotopes from enamel and collagen, and high resolution CT-scans of the cranium. Fossil Primates will be essential reading for advanced undergraduates and graduate students in evolutionary anthropology, primatology and vertebrate paleobiology.

Passive acoustic monitoring is increasingly used by the scientific community to study, survey and census marine mammals, especially cetaceans, many of which are easier to hear than to see. PAM is also used to support efforts to mitigate potential negative effects of human activities such as ship traffic, military and civilian sonar and offshore exploration. Walter Zimmer provides an integrated approach to PAM, combining physical principles, discussion of technical tools and application-oriented concepts of operations. Additionally, relevant information and tools necessary to assess existing and future PAM systems are presented, with Matlab code used to generate figures and results so readers can reproduce data and modify code to analyse the impact of changes. This allows the principles to be studied whilst discovering potential difficulties and side effects. Aimed at graduate students and researchers, the book provides all information and tools necessary to gain a comprehensive understanding of this interdisciplinary subject.

Current dominant thinking and practice in the private and public sectors asserts that peoples' development needs are in conflict with, or mutually exclusive to, the need to conserve the biosphere on which we depend. Consequently, we are asked to either diminish development in the name of conservation or diminish conservation in the name of development. Efforts to identify complementary objectives, or mutually acceptable trade-offs and compromises indicate, however, that this does not always have to be the case. This first volume in the State of the Apes series draws attention to the evolving context within which great ape and gibbon habitats are increasingly interfacing with extractive industries. Intended for a broad range of policy makers, industry experts, decision makers, academics, researchers and NGOs, these publications aim to influence debate, practice and policy, seeking to reconcile ape conservation and welfare, and economic and social development, through objective and rigorous analysis.

How do chimpanzees say, 'I want to have sex with you?' By clipping a leaf or knocking on a tree trunk? How do they eat live aggressive ants? By using a short stick with one hand or long stick with both? Ivorian and Tanzanian chimpanzees answer these questions differently, as would humans from France and China if asked how they eat rice. Christophe Boesch takes readers into the lives of chimpanzees from different African regions, highlighting the debate about culture. His ethnography reveals how simple techniques have evolved into complex ones, how teaching styles differ, how material culture widens access to new food sources and how youngsters learn culture. This journey reveals many parallels between humans and chimpanzees and points to striking differences. Written in a vivid and accessible style, Wild Cultures places the reader in social and ecological contexts that shed light on our twin cultures.

Within little more than a generation, whale-watching has been subject to global industrial development. It has been portrayed by destinations and business operators, and advocated by environmental groups, as a sustainable activity and an alternative to whaling. However, in recent years the sustainability of these activities has increasingly been questioned, as research shows that repeated disturbance by boat traffic can severely disrupt critical behaviours of cetaceans in the wild. Bringing together contributions by international experts, this volume addresses complex issues associated with commercial whale-watching, sustainable development and conservation of the global marine environment. It highlights widely expressed concerns for the failure of policy, planning and management and pinpoints both long-standing and emerging barriers to sustainable practice. Featuring numerous case studies, the book provides critical insights into the diverse socio-cultural, political, economic and ecological contexts of this global industry, highlighting the challenges and opportunities that arise along the pathways to sustainability.

Primates communicate with each other using a wide range of signals: olfactory signals to mark territories, screams to recruit help while fighting, gestures to request food and facial expressions to initiate play. Primate Communication brings together research on all forms of interchange and discusses what we know about primate communication via vocal, gestural, facial, olfactory and integrated multimodal signals in relation to a number of central topics. It explores the morphological, neural and cognitive foundations of primate communication through discussion of cutting-edge research. By considering signals from multiple modalities and taking a unified multimodal approach, the authors offer a uniquely holistic overview of primate communication, discussing what we know, what we don't know and what we may currently misunderstand about communication across these different forms. It is essential reading for researchers interested in primate behaviour, communication and cognition, as well as students of primatology, psychology, anthropology and cognitive sciences.

The giant panda is one of the world's most recognized animals. With the environment undergoing unprecedented change at a rapid and accelerating rate, can such a highly specialized species survive? This 2006 book summarizes panda biology and encompasses topics such as reproduction, behaviour, nutrition, genetics and veterinary medicine. It also provides information on veterinary management, advances in neonatal care, disease detection and prevention and the use of 'assisted breeding' to promote reproduction and preserve genetic diversity, as the females are sexually receptive for only 3 days per year and generally produce twins, but often lose one due to maternal neglect. This book provides the scholarly knowledge that will help conserve this treasured species in nature, while there is still time.

These discoveries have led to significant developments in our understanding of this unique group of mammals. The impact of these developments have been such that marsupials are coming to be seen as model organisms in studies of life history evolution, ageing and senescence, sex determination and the development and regeneration of the nervous system. This volume brings together information scattered throughout the primary literature. Coverage includes evolutionary history and management strategies as well as all aspects of basic biology. A complete listing of known species and a comprehensive list of references make this a unique repository of information on this fascinating group of animals.

Spider monkeys are one of the most widespread New World primate genera, ranging from southern Mexico to Bolivia. Although they are common in zoos, spider monkeys are traditionally very difficult to study in the wild, because they are fast moving, live high in the canopy and are almost always found in small subgroups that vary in size and composition throughout the day. This book is an assimilation of both published and previously unpublished research. It is a comprehensive source of information for academic researchers and graduate students interested in primatology, evolutionary anthropology and behavioral ecology and covers topics such as taxonomy, diet, sexuality and reproduction, and conservation.

Advances in morphological and molecular methods continue to uncover new information on the origin and evolution of bats. Presenting some of the most remarkable discoveries and research involving living and fossil bats, this book explores their evolutionary history from a range of perspectives. Phylogenetic studies based on both molecular and morphological data have established a framework of evolutionary relationships that provides a context for understanding many aspects of bat biology and diversification. In addition to detailed studies of the relationships and diversification of bats, the topics covered include the mechanisms and evolution of powered flight, evolution and enhancement of echolocation, feeding ecology, population genetic structure, ontogeny and growth of facial form, functional morphology and evolution of body size. The book also examines the fossil history of bats from their beginnings over 50 million years ago to their diversification into one of the most globally wide-spread orders of mammals living today.

Sexual compatibility between male and female partners is in dispensable to normal and successful fertilization in mammals. Thus, the genes from males and females whose sexual behavior is characterized by awkwardness, ineptness, and miscues are elimi nated from the gene pool of the species. In human societies, this compatibility is not always evident; and the behavior that precedes and accompanies copulation and fertilization is exceed ingly complex and affected by many variables. As in most other species of animals, the entire repertoire of reproductive behavior of man is not well understood by man. When viewed, discussed, or reported, the topic is too often and most unfortunately regarded as an amalgam of emotion, mysticism, and biology. In the past, such emotion-charged approaches to the biologi cal fact of reproduction did much to obfuscate the subject; and as a result, much of the array of hormonal, neural, psychological, and social variables that control and insure the successful repro duction of the human species remains even now in Victorian ignor ance. But with the recent rash of books and scientific treatises on the subject, some progress has been made in elucidating human reproduction and associated sexual behavior. However, so entrench ed are some of our social taboos that the danger still lurks of equating social acceptance of the words with an understandin- all too lacking--of the process to which they refer."

The Arashiyama group of Japanese macaques holds a distinguished place in primatology as one of the longest continuously studied non-human primate populations in the world. The resulting long-term data provide a unique resource for researchers, allowing them to move beyond cross-sectional studies to tackle larger issues involving individual, matrilineal and group histories. This book presents an overview of the scope and magnitude of research topics and management efforts that have been conducted on this population for several decades, covering not only the original troop living around Kyoto, Japan, but also the two subgroups that were translocated to Texas, USA and Montreal, Canada. The chapters encompass topics including life history, sexual, social and cultural behaviour and ecology, giving an insight into the range of current primatological research. The contributors underscore the historic value of the Arashiyama macaques and showcase new and significant research findings that highlight their continuing importance to primatology.

Chimpanzees are humanity's closest living relations and are of enduring interest to a range of sciences, from anthropology to zoology. In the West, many know of the pioneering work of Jane Goodall, whose studies of these apes at Gombe in Tanzania are justly famous. Less well-known, but equally important, are the studies carried out by Toshisada Nishida on the eastern shore of Lake Tanganyika. Comparison between the two sites yields both notable similarities and startling contrasts. Nishida has written a comprehensive synthesis of his work on the behaviour and ecology of the chimpanzees of the Mahale Mountains. With topics ranging from individual development to population-specific behavioural patterns, it reveals the complexity of social life, from male struggles for dominant status to female travails in raising offspring. Richly illustrated, the author blends anecdotes with powerful data to explore the fascinating world of the chimpanzees of the lakeshore.

How do males become male and females become female? And what are the consequences if the decision is not incisive? Drawing upon interests in animal genetics and molecular biology, the author endeavours to answer these difficult yet fascinating questions. Originally published in 1995, this book describes the genetic determination of sex and examines how sexual organs are differentiated. Using examples of intersexuality, chimaeras and asymmetries, the book describes the underlying molecular basis of sex determination and sexual differentiation, and focuses on the critical role of the rate of embryonic development in these vital processes. Male precocity is a recurrent theme, as is the involvement of Sertoli cells and their secretion of anti-Mullerian hormone. An invaluable book for reproductive physiologists, geneticists and developmental biologists whose interests may extend from animal science through veterinary medicine to human clinical medicine.

This integrated approach opens up new opportunities to study the behavioural ecology of some of the most endangered primates and to collect information on previously studied populations. Chapters include methodological techniques; instructions on collecting, processing and preserving samples/data for later analysis; ethical considerations; comparative costs; and further reading, making this an invaluable tool for postgraduate students and researchers in primatology, behavioural ecology and zoology.

Evolutionary maternal effects occur whenever a mother's phenotypic traits directly affect her offspring's phenotype, independent of the offspring's genotype. Some of the phenotypic traits that result in maternal effects have a genetic basis, whereas others are environmentally determined. For example, the size of a litter produced by a mammalian mother - a trait with a strong genetic basis - can affect the growth rate of her offspring, while a mother's dominance rank - an environmentally determined trait - can affect the dominance rank of her offspring. The first volume published on the subject in more than a decade, "Maternal Effects in Mammals" reflects advances in genomic, ecological, and behavioral research, as well as new understandings of the evolutionary interplay between mothers and their offspring. Dario Maestripieri and Jill M. Mateo bring together a learned group of contributors to synthesize the vast literature on a range of species, highlight evolutionary processes that were previously overlooked, and propose new avenues of research. "Maternal Effects in Mammals" will serve as the most comprehensive compendium on and stimulus for interdisciplinary treatments of mammalian maternal effects.
