Thomas Allen Jefferson – författare

With coverage on all the marine mammals of the world, authors Jefferson, Webber, and Pitman have created a user-friendly guide to identify marine mammals alive in nature (at sea or on the beach), dead specimens "in hand, and also to identify marine mammals based on features of the skull. This handy guide provides marine biologists and interested lay people with detailed descriptions of diagnostic features, illustrations of external appearance, beautiful photographs, dichotomous keys, and more. Full color illustrations and vivid photographs of every living marine mammal species are incorporated, as well as comprehendible maps showing a range of information. For readers who desire further consultation, authors have included a list of literature references at the end of each species account. For an enhanced understanding of habitation, this guide also includes recognizable geographic forms described separately with colorful paintings and photographs. All of these essential tools provided make Marine Mammals of the World the most detailed and authoritative guide available!* Contains superb photographs of every species of marine mammal for accurate identification * Authors'' collective experience adds up to 80 years, and have seen nearly all of the species and distinctive geographic forms described in the guide * Provides the most detailed and anatomically accurate illustrations currently available * Special emphasis is placed on the identification of species in "problem groups, such as the beaked whales, long-beaked oceanic dolphin, and southern fur seals * Includes a detailed list of sources for more information at the back of the book.

This new edition of Marine Mammals of the World describes and illustrates newly discovered and rarely photographed species, making it the most comprehensive and up-to-date identification guide available.This edition continues to meet the research-focused needs of marine biologists and conservation biologists by providing a tremendous influx of new photos, taking advantage of advances in digital and auto-focusing photography, and the emergence of marine mammal studies and "whalewatching" around the world. The book encompasses cetacean, pinniped, and sirenian species, as well as extinct species, and describes basic biology and taxonomic groupings of marine mammals.- Contains superb photographs of every species of marine mammal for accurate identification- Authors possess nearly 80 years of collective experience with almost all of the species and distinctive geographic forms described in the guide- Provides the most detailed and anatomically accurate illustrations currently available, including more than 750 new illustrations- Special emphasis is placed on the identification of species in "problem groups," such as the beaked whales, long-beaked oceanic dolphins, and southern fur seals- Includes a detailed list of sources for more information- Contains updated taxonomy including four new species

Humpback Dolphins (Sousa spp.): Current Status and Conservation, Part 1 is part of Advances in Marine Biology, a series that has been providing in-depth and up-to-date reviews on all aspects of marine biology since 1963 - more than 50 years of outstanding coverage from a reference that is well known for its contents and editing.

This latest addition to the series includes updates on many topics that will appeal to postgraduates and researchers in marine biology, fisheries science, ecology, zoology, and biological oceanography.

Specialty areas for the series include marine science, both applied and basic, a wide range of topical areas from all corners of marine ecology, oceanography, fisheries management, and molecular biology, and the full range of geographic areas from polar seas to tropical coral reefs.

Oceanic Dolphins: Ridgway and Harrison's Handbook of Marine Mammals, Volume Two in the Handbook of Marine Mammals series, focuses on dolphins, the remarkable marine mammals that live in our seas and oceans. For centuries, dolphins have fascinated humans with their intelligence and adaptability. As our understanding of marine mammals expands, there is a growing need for comprehensive references on their ecology and biology. This series, created to meet this need, provides definitive reviews of all living species of whales, dolphins, porpoises, seals, sea lions, sea cows, and marine otters and bears.This volume features chapters written by leading global experts on offshore and oceanic dolphin species. Each chapter includes detailed descriptions of the species, covering aspects such as distribution and abundance, anatomy, physiology, behavior, ecology, reproduction, parasites and diseases, and the effects of human activities on these species.

Provides in-depth reviews of Stenella dolphin species, common dolphins, killer whales, pilot whales, and other dolphins found in more offshore watersAddresses the evolution, anatomy, ecology, distribution, and behavior of these marine mammal speciesFeatures numerous photos of live and specimen animals, skulls, and anatomical details, plus distribution maps
