We teach our students of behavioural science that one first defines a research problem, and then the most appropriate animal is selected to investigate hypotheses. The reverse order of events is improper: a particular class of animals should not be studied for its own sake. In the case of the Pinnipeds (seals, sea lions, fur seals and walruses) the organism and the problem are essentially the same. The research questions presented in this volume in one way or another relate to survival in two worlds, the ocean for foraging, and the terrain at its edge or frozen above it for breeding. The evolution of Pinniped behaviour and the mechanisms which underlie it are a consequence of having to cope with two seemingly incompatible sets of environmental constraints. The physiological adaptations for concomitant functioning in two media with very different physical characteristics have produced correlated behav ioural modifications. The energetic demands of reproduction and foraging are idiosyncratic because each activity occurs on opposite sides of the air/water interface. As a result, the mating system must reconcile aquatic design for such functions as locomotion and thermoregulation, with the terrestrial requirements for successful pupping. Similarly, the ecology of this dual habitat prescribes the rules governing the behaviour of the neonate and its interactions with its mother.

The largest of all seals, elephant seals rank among the most impressive of marine mammals. They are renowned for their spectacular recovery from near-extinction at the end of the nineteenth century when seal hunters nearly eliminated the entire northern species. No other vertebrate has come so close to extinction and made such a complete recovery. The physiological extremes that elephant seals can tolerate are also remarkable: females fast for a month while lactating, and the largest breeding males fast for over one hundred days during the breeding seasons, at which times both sexes lose forty percent of their body weight. Elephant seals dive constantly during their long foraging migrations, spending more time under water than most whales and diving deeper and longer than any other marine mammal. This first book-length discussion of elephant seals brings together worldwide expertise from scientists who describe and debate recent research, including the history and status of various populations, their life-history tactics, and other findings obtained with the help of modern microcomputer diving instruments attached to free-ranging seals. Essential for all marine mammalogists for its information and its methodological innovations, Elephant Seals will also illuminate current debates about species extinctions and possible means of preventing them. This title is part of UC Press's Voices Revived program, which commemorates University of California Press’s mission to seek out and cultivate the brightest minds and give them voice, reach, and impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand technology. This title was originally published in 1994.

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.

"Everyone knows how babies are made, but scientists are only just beginning to understand the making of a mother. Mom Genes reveals the hard science behind our tenderest maternal impulses, tackling questions such as whether a new mom's brain ever really bounces back, why mothers are destined to mimic their own moms (or not), and how maternal aggression makes females the world's most formidable creatures."--Publisher's description.

Mammalian sociobiology is a rapidly advancing field which has made enormous strides in the last ten years. The last major monograph on the subject (Ewer, 1968) was published sixteen years ago, and there is a need for this information to be examined in terms of modern sociobiological theory. My approach throughout is evolutionary and is therefore directed strongly towards research which throws light on the ways in which mammals behave in their natural environments. I have tried to cover as wide a range of mammalian species as possible, although, in some cases, the only data available were obtained from captive individuals. The coverage of this book is not a reflection of the volume of literature published on different species, as I have tried to avoid undue emphasis on the social behaviour of primates and laboratory rodents. I have made scrupulous efforts throughout to avoid an anthropomorphic approach to mammalian behaviour. Terms such as 'strategy', 'evaluation' or 'choice' do not therefore imply conscious planning, but are used neutrally in the way in which they would be applied to a chess-playing computer. In the case of mammals, the programmer was natural selection. While I am fully aware that human beings are mammals, any detailed consideration of human social behaviour lies outside the scope of this book. However, the book may provide a complementary text to those interested in that subject.
