Samoan Land Snails and Slugs - An Identification Guide
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.
The Recent Apple Snails of Africa and Asia (Mollusca: Gastropoda: Ampullariidae: Afropomus, Forbesopomus, Lanistes, Pila, Saulea)
Ampullariidae are freshwater snails predominantly distributed in humid tropical and sub-tropical habitats in Africa, South and Central America and Asia. This catalogue is concerned only with the non-fossil Old World species, the majority of which are placed in the genera Pila and Lanistes, with a few species in Afropomus, Forbesopomus and Saulea. Pila occurs in Africa and Asia, Lanistes, Afropomus and Saulea only in Africa and Forbesopomus only in Asia. New World taxa were catalogued in a previous publication. The taxonomy of the group is heavily based on shell morphology but the true number of valid taxa remains unknown, pending revisionary work. This catalogue provides the rigorous nomencl...
A World in a Shell
Following the trails of Hawai‘i’s snails to explore the simultaneously biological and cultural significance of extinction. In this time of extinctions, the humble snail rarely gets a mention. And yet snails are disappearing faster than any other species. In A World in a Shell, Thom van Dooren offers a collection of snail stories from Hawai‘i—once home to more than 750 species of land snails, almost two-thirds of which are now gone. Following snail trails through forests, laboratories, museums, and even a military training facility, and meeting with scientists and Native Hawaiians, van Dooren explores ongoing processes of ecological and cultural loss as they are woven through with pos...
Journey to a Waterfall A Biologist in Africa
From the age of ten, the author was determined to be involved with African wildlife. This memoir recounts how he was able to fulfil this dream, travelling through Kenya, Tanzania, Ethiopia, Sudan, Zimbabwe, Malawi and Egypt, as well as the Yemen, which biologically is almost Africa. He tells of being captured by Eritrean guerillas, seeing Gelada baboons in the Ethiopian highlands and the huge migrations of zebra and wildebeest in the Serengeti, doing research on termites in Darfur as well as assessing agricultural problems in the highest fastnesses of the Yemeni mountains, gazing in awe at the Pyramids of Giza and marvelling at the Victoria Falls in full flo
Hawaiian Natural History, Ecology, and Evolution
Not since Willam A. Bryan's 1915 landmark compendium, Hawaiian Natural History, has there been a single-volume work that offers such extensive coverage of this complex but fascinating subject. Illustrated with more than two dozen color plates and a hundred photographs and line drawings, Hawaiian Natural History, Ecology, and Evolution updates both the earlier publication and subsequent works by compiling and synthesizing in a uniform and accessible fashion the widely scattered information now available. Readers can trace the natural history of the Hawaiian Archipelago through the book's twenty-eight chapters or focus on specific topics such as island formation by plate tectonics, plant and animal evolution, flightless birds and their fossil sites, Polynesian migrational history and ecology, the effects of humans and exotic animals on the environment, current conservation efforts, and the contributions of the many naturalists who visited the islands over the centuries and the stories behind their discoveries. An extensive annotated bibliography and a list of audio-visual materials will help readers locate additional sources of information.
Perry's Arcana
From 1810 to 1811, the English stonemason and amateur naturalist George Perry published a lavishly illustrated magazine on natural history. The Arcana or Museum of Nature ran to 22 monthly parts, with 84 extraordinary hand-colored plates and over 300 text pages describing mammals, birds, reptiles, fish, mollusks, echinoderms, insects, trilobites and plants, alongside travelogues from far-off lands. It presented the first published illustration of the koala and many new genera and species, but astonishingly was then largely forgotten for nearly two hundred years. Perry’s work was deliberately ignored by his contemporaries in England, as he was a supporter of Lamarck rather than of Linnaeus,...
