The islands of the Samoan archipelago lie about 14 degrees south of the equator in the central Pacific Ocean. Politically, they are divided into two groups: Samoa (formerly Western Samoa), an indepedent state and American Samoa, a territory of the USA. The islands have been formed as a result of complex volcanic activity; they are geologically young. While many of the plants and birds of the Samoan Islands are found elsewhere in the Pacific, many of the snail species are found nowhere else on Earth. This guide is intended to permit identification of mos of the terrestrial snails, and slugs of the Samoan Islands. It is intended to be accessible to the amateur naturalist but also to provide the experienced scientist with a compact resource of information. The guide covers both the native species and the non-native, introduced species, which are generall more frequently encountered, especially at low elevations and in habits disturbed by human activities.

Features descriptions and beautiful color illustrations of over 400 species of marine and terrestrial fauna found in the ecosystems of Samoa's coral reefs, ocean waters, sea grass beds, rain forests, mangrove forests, and wetlands.

This book provides the first coherent examination of the vast literature on the diversity of organisms that constitute the natural enemies of terrestrial molluscs. In a series of review chapters, it provides an authoritative synthesis of current research on predators, parasites and pathogens and how they might be used to control mollusc pests.

Mollusc species currently constitute a major threat to sustainable agriculture. This threat is associated with cultivation of new crops, intensification of agricultural production systems and the spread through human trade and travel of species adapted to these modified environments. In some crops their significance is only now becoming apparent with the decline in the importance of other pest groups which can be effectively controlled. The book focuses on: toxicology of chemicals; deployment of molluscicides in baits; specific crop situations worldwide; current pest status of mollusc species and progress towards development of solutions.

Tangatatau Rockshelter on Mangaia Island in the Southern Cook Islands, excavated by a multidisciplinary team in 1989-1991, produced one of the richest stratigraphic sequences of artifacts, faunal assemblages, and archaeobotanical materials in Eastern Polynesia. More than seventy radiocarbon dates provide a tight chronology from AD 1000 to European contact in about 1800. The faunal assemblage provides compelling evidence for dramatic reductions in indigenous bird life following Polynesian colonization, one of the best documented cases for human-induced impacts on island biota. Tangatatau is unique among Polynesian archaeological sites in the extent to which fishing was dominated by freshwater fishes and eels. The site also yielded an extensive suite of carbonized plant materials, including sweet potato tubers, demonstrating that this South American domesticate had reached Eastern Polynesia by AD 1400. Mangaia illustrates the often far-reaching consequences of human land use and resource exploitation on small and vulnerable islands.

Five articles on different species of snails: Georissa, Partula zebrina, Endodonta, Pupoidopsis Hawaiiensis, and Achatinellidae from Hawaiʻi, Christmas Island, and Samoa.
