Four years ago we began soliciting articles for this volume from authors who were engaged in comprehensive research on whales. From the outset we decided not to limit the subject matter to behavior but to also include natural history. Much of what is known about the behavior of whales arose from studies whose principal aim was not behavior, much as it did for other animal groups before behavior was considered a distinct discipline. Thus in many of the articles behavior is closely intertwined with natural history and in others is completely overshadowed by a basic natural history approach. Our aim was to have the articles contain a review of the literature and include research findings not pr...
Includes articles devoted to wide range of topics -- from the specific behavior and physiology of cetaceans and pinnipeds, to ecology, population biology, human effects and interaction, and research methodology.

Once hunted by whalers and now the darling of ecotourists, the gray whale has become part of the culture, history, politics, and geography of Mexico's most isolated region. After the harvesting of gray whales was banned by international law in 1946, their populations rebounded; but while they are no longer hunted for their oil, these creatures are now chased up and down the lagoons of southern Baja California by whalewatchers. This book uses the biology and politics associated with gray whales in Mexican waters to present an unusual case study in conservation and politics. It provides an inside look at how gray whale conservation decisions are made in Mexico City and examines how those polic...
