Book Description
This book provides a modern, synthetic overview of what is known about the structure, functioning and interactions of marine and terrestrial systems at the Prince Edward Islands. Building on more than 50 years of biological, geological, meteorological, and oceanographic research, it demonstrates not only how inextricably linked marine and terrestrial systems at the islands are, but also how global environmental challenges, such as climate change, biological invasions, and over exploitation, are playing out at the regional and local levels in the Southern Ocean.

Book Description
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.

Book Description
The present volume was conceived as a companion to 'Antarctic Oasis: Terrestrial environments and history of the Vestfold Hills' edited by J. Pickard and published in 1986 by Academic Press, Sydney. Pickard's book contains accounts of the Vestfold Hills' climate (N. A. Streten) and recent geomorphological history (D. A. Adamson & J. Pickard) which provide a valuable context for understanding their present day biology. Pickard also gives a history of human discovery and occupation of the Vest fold Hills. There is some overlap in the coverage, to the extent that both this volume and Pickard's book describe the terrestrial flora and fauna. The reader specifically interested in the terrestrial ecosystems of the Vestfold Hills should draw from both sources. Together, these works present a broad and descriptive account of the largest truly coastal antarctic oasis: a region that holds a unique variety of opportunities for future scientific investigation. There are several tasks I wish to accomplish here, apart from expressing my sincere thanks to the many people who have contributed to the completion of this volume. I wish to briefly introduce the Vestfolds and to list some of the features that, in my opinion, make them biologically varied, and unique in the context of other coastal ice-free areas. I wish to describe the phases of biological research in this region, including the directions that have been pursued since the 1984 symposium and to comment upon the future of the Vestfold Hills.

Book Description
"This third, extensively revised edition of The Mammals of the Southern African Subregion contains detailed descriptions of all mammals that occur naturally on the African mainland south of the Cunene and Zambezi rivers, together with all mammals indigenous to the subregion's coastal waters. The rapid accumulation of new information resulting from mammal research in southern Africa, together with radical taxonomic changes across all levels of mammalian classification, have necessitated this new edition, which presents the best and latest data accurately in one comprehensive volume for use not only by scientists but also by an increasingly wide audience of general readers with an interest in the natural history of southern Africa." "J. D. Skinner and C. T. Chimimba have revised, expanded and updated the text in a major project overseen by an editorial committee constituted by the Mammal Research Institute at the University of Pretoria. Specialists on each mammalian order have served as subeditors, and a range of independent and internationally recognised authorities have reviewed every species description." "In this edition all the distribution maps and many of the illustrations of mammal prints have been updated and redrawn, several new colour plates have been added, and the whole design of this definitive reference work has been enhanced to ensure easy access to information."--BOOK JACKET.
