Title: Dolphin societies: discoveries and puzzles
Author: Pryor, Karen 1932-
Published: University of California Press,  1991
Subjects: Science | Zoology | Natural History | Marine  and  Freshwater  Sciences
Publisher's Description: Wild dolphins are an elusive subject for behavioral studies: How can you "do a Jane Goodall" on animals usually visible only as a glimpse of rolling dorsal fins heading for the horizon? In this unusual book, two of the best-known scientists in the marine-mammal field have assembled an astonishing variety of discoveries about dolphins. The contributions range from a graduate student's first paper to senior scientists summarizing a lifetime of research. The dolphins they have studied range from tiny spinners to majestic pilot whales, from killer whales to the familiar bottle-nosed dolphin. The research tactics vary just as widely: the researchers have followed dolphins in boats, tracked them from shore, dived among hundreds of them (plus a few sharks) in tuna fishing nets. They have used computers and airplanes, genetic analysis and artificial language, and learned to read the life history of a dolphin from the cross-section of a single tooth.Pryor and Norris are successful writers as well as scientists; the book is peppered with entertaining essays, by one or both editors, on the intriguing history of dolphin research. Dolphin Societies not only surveys the most interesting recent research on dolphin behavior but also gives lay readers a fascinating look at the scientific mind at work.   [brief]

Title: California's salmon and steelhead: the struggle to restore an imperiled resource online access is available to everyone
Author: Lufkin, Alan
Published: University of California Press,  1990
Subjects: Environmental Studies | Ecology | California and the West | Marine  and  Freshwater  Sciences
Publisher's Description: Millions upon millions of salmon and steelhead once filled California streams, providing a plentiful and sustainable food resource for the original peoples of the region. But over the years, dams and irrigation diversions have reduced natural spawning habitat from an estimated 6,000 miles to fewer than 300. River pollution has also hit hard at fish populations, which within recent decades have diminished by 80 percent. One species, the San Joaquin River spring chinook, became extinct soon after World War II. Other species are nearly extinct.This volume documents the reasons for the decline; it also offers practical suggestions about how the decline might be reversed. The California salmon story is presented here in human perspective: its broad historical, economic, cultural, and political facets, as well as the biological, are all treated. No comparable work has ever been published, although some of the material has been available for half a century.In the richly varied contributions in this volume, the reader meets Indians whose history is tied to the history of the salmon and steelhead upon which they depend; commercial trollers who see their livelihood and unique lifestyle vanishing; biologists and fishery managers alarmed at the loss of river water habitable by fish and at the effects of hatcheries on native gene pools. Women who fish, conservation-minded citizens, foresters, economists, outdoor writers, engineers, politicians, city youth restoring streambeds - all are represented. Their lives - and the lives of all Californians - are affected in myriad ways by the fate of California's salmon and steelhead.   [brief]

Title: Sea cliffs, beaches, and coastal valleys of San Diego County: some amazing histories and some horrifying implications online access is available to everyone
Author: Kuhn, Gerald G
Published: University of California Press,  1984
Subjects: Geography | California and the West | Marine  and  Freshwater  Sciences | Geology | Ecology
Publisher's Description: California's coastal zones are areas of extreme vulnerability, subject to the vicissitudes of weather and prone to erosion, landslides, and flooding. Gerald Kuhn and Francis Shepard examine and analyze these threats to coastal stability in a thought-provoking and detailed study of the coastal area of San Diego County from the nineteenth century to the present. An invaluable resource for oceanographers, geologists, meteorologists, coastal engineers, property owners, developers, and planning and regulatory agencies.   [brief]
