This volume constitutes the most recent and most comprehensive consideration of the largest family of bony fishes, the Cichlidae. This book offers an integrated perspective of cichlid fishes ranging from conservation of threatened species to management of cichlids as invasive species themselves. Long-standing models of taxonomy and systematics are subjected to the most recent applications and interpretations of molecular evidence and multivariate analyses; and cichlid adaptive radiations at different scales are elucidated. The incredible diversity of endemic cichlid species in African lakes is revisited as possible examples of sympatric speciation and as serious cases for management in complex anthropogenic environments. Extreme hydrology and bathymetry as driver of micro-allopatric speciation is explored in the African riverine hotspot of diversity of the lower Congo River. Dramatic new molecular evidence draws attention to the complex taxonomy and systematics of Neotropical cichlids including the crater lakes of Central America. Molecular genetics, genomics, imaging tools and field study techniques assess the roles of natural, sexual and kin selection in shaping cichlid traits and beyond. The complex behavioral adaptations of cichlids are considered from a number of sub-disciplines including sensory biology, neurobiology, development, and evolutionary ecology. Most importantly, this volume puts forth a wealth of new interpretations, explanatory hypotheses and proposals for practical management and applications that will shape the future for these remarkable fishes in nature as well as their use as models for the study of biology.

This series of volumes represents a comprehensive and integrated treatment of reproduction in vertebrates from fishes of all sorts through mammals. It is designed to provide a readable, coordinated description of reproductive basics in each group of vertebrates as well as an introduction to the latest trends in reproductive research and our understanding of reproductive events. Whereas each chapter and each volume is intended to stand alone as a review of that topic or vertebrate group, respectively, the volumes are prepared so as to provide a thorough topical treatment across the vertebrates. Terminology has been standardized across the volumes to reduce confusion where multiple names exist in the literature, and a comprehensive glossary of these terms and their alternative names is provided.
*A complete, essential and up to date reference for research scientists working on vertebrate hormones and reproduction - and on animlals as models in human reproductive research.
*Covers the endocrinology, neuroendocrinology, physiology, behaviour and anatomy of vertebrate reproduction.
*Structured coverage of the major themes for all five vertebrate groups allows a consistent treatment for all.
*Special chapters elaborate on features specific to individual vertebrate groups and to comparative aspects, similarities and differences between them.

From the New York Times bestselling author of The Genius of Birds, a radical investigation into the bird way of being, and the recent scientific research that is dramatically shifting our understanding of birds -- how they live and how they think. "There is the mammal way and there is the bird way." But the bird way is much more than a unique pattern of brain wiring, and lately, scientists have taken a new look at bird behaviors they have, for years, dismissed as anomalies or mysteries -- What they are finding is upending the traditional view of how birds conduct their lives, how they communicate, forage, court, breed, survive. They are also revealing the remarkable intelligence underlying these activities, abilities we once considered uniquely our own: deception, manipulation, cheating, kidnapping, infanticide, but also ingenious communication between species, cooperation, collaboration, altruism, culture, and play. Some of these extraordinary behaviors are biological conundrums that seem to push the edges of, well, birdness: a mother bird that kills her own infant sons, and another that selflessly tends to the young of other birds as if they were her own; a bird that collaborates in an extraordinary way with one species-ours-but parasitizes another in gruesome fashion; birds that give gifts and birds that steal; birds that dance or drum, that paint their creations or paint themselves; birds that build walls of sound to keep out intruders and birds that summon playmates with a special call-and may hold the secret to our own penchant for playfulness and the evolution of laughter. Drawing on personal observations, the latest science, and her bird-related travel around the world, from the tropical rainforests of eastern Australia and the remote woodlands of northern Japan, to the rolling hills of lower Austria and the islands of Alaska's Kachemak Bay, Jennifer Ackerman shows there is clearly no single bird way of being. In every respect, in plumage, form, song, flight, lifestyle, niche, and behavior, birds vary. It is what we love about them. As E.O Wilson once said, when you have seen one bird, you have not seen them all.

Information is a core concept in animal communication: individuals routinely produce, acquire, process and store information, which provides the basis for their social life. This book focuses on how animal acoustic signals code information and how this coding can be shaped by various environmental and social constraints. Taking birds and mammals, including humans, as models, the authors explore such topics as communication strategies for "public" and "private" signaling, static and dynamic signaling, the diversity of coded information and the way information is decoded by the receiver. The book appeals to a wide audience, ranging from bioacousticians, ethologists and ecologists to evolutionary biologists. Intended for students and researchers alike, it promotes the idea that Shannon and Weaver's Mathematical Theory of Communication still represents a strong framework for understanding all aspects of the communication process, including its dynamic dimensions.

This book examines the biology of tuco-tucos (Ctenomys) from an evolutionary perspective. Historically, these subterranean rodents have long attracted the attention of scientists due to its remarkable chromosomes variability and rapid diversification. A wealth of knowledge on physiology, ecology, genetics, morphology, paleontology, and taxonomy has been documented in the last 70 years through numerous single publications. In this volume, expert investigators review and frame these essays with the breadth of current understanding. The collection of chapters are presented into the major topics: i) Evolution of Ctenomys, ii) Geographic Patterns, iii) Organismal Biology, and iv) Environmental Relationships. Given its scope, the book will be of interest to both students and researchers and may stimulate further research with this exciting model on a wide range of evolutionary topics.

This book offers a valuable resource, reviewing the current state of knowledge concerning the pathology and epidemiology of infectious diseases in both captive and wild monkeys. The One Health concept forms the framework of all chapters. The multidisciplinary team of authors addresses neglected diseases caused by the three major pathogen groups - bacteria, viruses, and parasites. Moreover, the volume discusses key virulence factors such as the evolution of antibiotic resistance, and the ecological drivers of and human influence on pathogen transmission. Demonstrating how researchers working on monkeys diseases are increasingly thinking outside the box, this volume is an essential reference guide to the field of One Health and will serve as an asset for stakeholders in conservation, healthcare and research organizations that face the challenge of moving beyond classical human oriented approaches to health.
