Despite their rich fossil history, there are only four surviving species of sirenians or sea cows, the only fully aquatic herbivorous mammals. The three species of manatees and the dugong live in the coastal waters rivers and lakes of more than 80 tropical and subtropical countries and are all on the IUCN Red List of Threatened Species. This book examines sirenian conservation biology through the lens of their behavioral ecology and ethology. Sirenian feeding, diving, movement, social and reproductive behaviors are reviewed by an international team of scientists from eight countries, with an emphasis on data gathered in the past 15 years.  

Owls are one of the most fascinating bird families. They have inspired much folklore and superstition worldwide. This book discusses this nocturnal species and their unique physiology and anatomy. It includes owl studies from countries including Bulgaria, Ecuador, Iraq, Slovakia, Syria, and Africa.

"Many pet dogs are experiencing anxiety and frustration as they struggle to adapt to human home environments--despite being pampered, poofed, and petted, or perhaps in part because of this. We can do better for them. Who's a Good Dog challenges us to think more carefully about the limits we place on their inherited, deep-rooted behaviors. Bioethicist Jessica Pierce explores common practices of caring for, socializing, and training pet dogs. She asks broader ethical questions and helps us think more critically about what we expect of our dogs. She offers resources to help readers cultivate kindness and more mindful attentiveness. This work is about the art of noticing, of astonishment, of looking with fresh eyes (and noses!) at these dear beings we think we know. Pierce avoids judgement while taking a clear stance on important issues, connecting her research to her relationship with Bella, the dog in her life"--

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.

This volume presents selected issues in the complex and diverse science of animal husbandry. The use of computer programs provides an opportunity to improve breeding and optimize farm management. At the same time, the use of traditional breeding methods is also of decisive importance. Knowledge of animal welfare and animal wellness is of great help in controlling animal health issues and in economic production. In the biological processes of reproduction of dairy cows, the events of the 100 days after calving are of fundamental importance. Production systems influence the process of product production, in which the relationship between animal products and human health goes far beyond animal husbandry, and to which the issue of greenhouse gases is also connected. The quality of manufactured meat products is influenced by both on-farm and off-farm factors, but good meat cannot be produced from low-quality animals, even with excellent slaughterhouse work. Background knowledge of animal health ¿ including the microbiome in the digestive tract, which makes use of the feed ¿ makes this activity more effective, which is of particular importance in the case of broiler chickens. Knowing the behavioural characteristics of animals (rams) enables better management. Many horse breeds are capable of artificial gaits as a result of breeding and selection processes. Comparative knowledge of the movements of these horse breeds also helps to understand their differences. The quality of life of animals and the quality of manufactured products are also affected by polycyclic aromatic hydrocarbons from the environment, which, being stored and enriched in fat-containing tissues, can also have adverse effects on the human consumer. Each topic presented not only offers specialist knowledge but makes interesting reading in its own right.

Temple Grandin is famous for her groundbreaking approach to decoding animal behavior. Her 40 + years of experience in observing animals is detailed in The Animal Welfare Journals. Her professional training as a scientist and her history as a person with autism have given her a perspective like that of no other expert in the field of animal science.

"Descended from shy, solitary North African wild cats, domestic cats set up homes with devoted owners all over the world by learning how to talk to us. This book translates-in case you missed anything. A renowned cat behavior scientist of over thirty years, Dr. Sarah Brown has been at the forefront of research in the field, discovering how cats use tail signals to interact with each other and their owners. Now, she reveals the previously unexplored secrets of cat communication in a book that is both scientifically grounded and utterly delightful. Each chapter dives into a different form of communication, including vocalizations, tail signals, scents, rubbing, and ear movements. The iconic meow, for example, is rarely used between adult cats-cleverly mimicking the cries of a human infant, the meow is a feline invention for conversing with people. Through observing the behavior of two cat colonies in rural England, readers will also have the opportunity to glimpse into the lives of some of the cats behind Dr. Brown's science. Can we understand what cats' meows and other signals mean? How do cats actually perceive us? And how can we use this information to inform how we talk back to our feline friends? Referencing historical records, exploring modern scientific studies of cat-human communication, and including simple, elegant line drawings, The Hidden Language of Cats is perfect for any cat lover who wants to learn more about their companion"--

The title refers to the legendary Seal of Solomon, a ring that supposedly gave King Solomon the power to speak to animals. Lorenz claimed to have achieved this feat of communication and of being "understood" by several species, by raising them in and around his home and observing their behavior and personally interacting with them. King Solomon's Ring describes the scientific methods of his investigation and his fascinating resulting conclusions about animal psychology.

This volume brings together the world's leading experts on disgust to fully explore this understudied behavior. Disgust is unique among emotions. It is, at once, perhaps the most ¿basic¿ and visceral of feelings while also being profoundly shaped by learning and culture. Evident from the earliest months of life, disgust influences individual behavior and shapes societies across political, social, economic, legal, ecological, and health contexts. As an emotion that evolved to prevent our eating contaminated foods, disgust is now known to motivate wider behaviors, social processes, and customs. On a global scale, disgust finds a place in population health initiatives, from hand hygiene to tobacco warning labels, and may underlie aversions to globalization and other progressive agendas, such as those regarding sustainable consumption and gay marriage.This comprehensive work provides cutting¿edge, timely, and succinct theoretical and empirical contributions illustrating thebreadth, rigor, relevance, and increasing maturity of disgust research to modern life. It is relevant to a wide range of psychological research and is particularly important to behavior viewed through an evolutionary lens, As such, it will stimulate further research and clinical applications that allow for a broader conceptualization of human behavior.The reader will find:Succinct and accessible summaries of key perspectivesHighlights of new scientific developmentsA rich blend of theoretical and empirical chapters

This book explores the answers to fundamental questions about the human mind and human behaviour with the help of two ancient texts. The first is Oedipus Rex (Oedipus Tyrannus) by Sophocles, written in the 5th century BCE. The second is human DNA, with its origins around 4 billion years ago, and continuously revised by chance and evolution. With Sophocles as a guide, the authors take a journey into the Genomic era, an age marked by ever-expanding insights into the human genome. Over the course of this journey, the book explores themes of free will, fate, and chance; prediction, misinterpretation, and the burden that comes with knowledge of the future; self-fulfilling and self-defeating prophecies; the forces that contribute to similarities and differences among people; roots and lineage; and the judgement of oneself and others.Using Oedipus Rex as its lens, this novel work provides an engaging overview of behavioural genetics that demonstrates its relevance across the humanities and the social and life sciences. It will appeal in particular to students and scholars of genetics, education, psychology, sociology, and law.

"From the New York Times bestselling author of The Genius of Birds and The Bird Way, a brilliant scientific exploration of owls, the most elusive group of birds, and an investigation into why these remarkable and yet mysterious animals exert such a hold on human imagination For centuries, owls have captivated and intrigued us. Our fascination with these mysterious birds was first documented over 30,000 years ago, in the Chauvet cave paintings in southern France, and our enduring awareness and curiosity of their forward gaze and nearly silent flight has cemented the owl as a symbol of wisdom and knowledge, foresight and intuition. But what, really, does an owl know? Though our infatuation goes back centuries, scientists have only recently begun to study these birds in great detail. While more than 270 species exist today, and reside on every continent except Antarctica, owls are far more difficult to find and study than other birds - because while not only cryptic and perfectly camouflaged, owls are most active in the dark of night. Joining scientists on this maddening and elusive treasure hunt, Jennifer Ackerman brings alive the rich biological history of these animals and reveals the remarkable scientific discoveries into their brains and behavior. She explores how, with the modern technology and tools, researchers now know that owls talk all night long - without opening their bills. That that their hoots follow a series of complex rules, allowing them to express needs and desires. That owls duet. They migrate. They use tools. They hoard their prey. Some live in underground burrows, some dine on scorpions. Ackerman brings this research alive with her own personal field observations about owls, and dives deep too into why this bird endlessly inspires and beguiles us. WHAT AN OWL KNOWS is an awe-inspiring and spellbinding journey across the globe and through human history, and a dazzling account of the astonishing health, hunting skills, communication, and sensory prowess that distinguishes the owl from nearly all other birds. An extraordinary glimpse into the mind of these brilliant animals, WHAT AN OWLS KNOWS pulls back the curtain on the the hidden and still undiscovered realities of our shared world"--

An Introduction to Hormones and Behavior explores the ways in which hormones modulate behavior and vice versa. The volume focuses on the key principles of the topic and features original readings from classic studies, as well as more recent research, to provide students with a holistic understanding of the interplay of hormones and behavior.The text begins with a chapter dedicated to endocrine principles and methods, then advances to discuss sexual differentiation, sex differences, and development. Later chapters address the distinctive characteristics and differences between male and female reproduction, as well as male and female parental behaviors. In the closing chapters, students learn about social behavior, stress, and how hormones influence human behavior. Each chapter features prewriting exercises, an introduction to provide context and background information, select readings, and critical thinking questions.The revised first edition includes two new readings, "Testosterone and Cortisol Release among Spanish Soccer Fans Watching the 2010 World Cup Final" and "Hormones and Sleep."An Introduction to Hormones and Behavior is an excellent resource for undergraduate and graduate courses in hormones and behavior, behavioral endocrinology, and physiological psychology.

A short description of the animal is followed with an acrostic poetry reflecting the animal behavior. Introducing the text a sketch or drawing of the animal inspired by the Chinese calligraphy.
