Book Description
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.

Book Description
Updated for 2013, Ecology is one title in the Britannica Illustrated Science Library Series. Long ago when people still lived in caves—perhaps at the same time when they developed habits that were different from those of other animals— humans began to practice ecology. They became keen observers of nature through such basic and instinctive actions as tracking both large wild animals and small prey, discerning edible plants from poisonous ones, and noting the time of year when different plants could be gathered. From necessity and inherent curiosity, humans began to learn about the relationships between living things and the environment. As the field of ecology grew, its focus went beyond the simple cataloging of living things in the world. Ecologists also became interested in understanding how living things function and how they interrelate with one another and with the environment—to explain that peculiar element that makes the Earth unique: life. We will begin by learning what ecology is and what it is not. (At times the word has been used incorrectly as a synonym for environmental protection.) Later, we will look at how living things are classified, before moving into the study of the environments in which they live: the land, water, and air.

Book Description
Research on snail-transmitted disease has continued at a considerable pace during the last twenty years, and sveral investigators have made valuable contributions to our knowledge of these diseases.The objective of this book is to present an up-to-date account of the infections or diseases of the world which are transmitted by snails, and in which each disease is considered in much greater detail than is usually provided by textbooks on general, medical or veterinary parasitology.These two volumes cover the infections or diseases that are caused by certain helminths which are transmitted by snails.

Book Description
Praise for the previous edition: "...make[s] high-level scientific concepts accessible to secondary students."—Library Journal "...clearly written and well organized..."—School Library Journal "Fulfilling educational benchmarks identified by the National Academy of Sciences, this encyclopedia is an excellent choice for both public and academic libraries. Recommended."—Choice "...a thorough and informative work...provide[s] accessible information...There is simply no other work that compares to this...High-school and public libraries will welcome such a well-researched title..."—Booklist "The text is suitable for high school students but advanced enough for adult readers, too...presents important biodiversity topics...a handy overview for term papers and class presentations."—Library Journal Biodiversity and ecology are founded in evolutionary science. In order to understand why species of organisms occupy different parts of the world, it is important to comprehend how they evolved. Encyclopedia of Biodiversity, Revised Edition examines this evolutionary framework with the help of more than 150 entries and five essays averaging at least 2,000 words each. High school teachers can use these entries—grouped by topic—to meet many of the science education goals established by the National Academy of Sciences. Written by a leading expert in the field, this comprehensive, full-color encyclopedia makes information about groups of organisms (from bacteria to mammals) and about ecological concepts and processes (such as biogeography and ecological succession) clearly and readily available to students and the general public. Tables at the end of each entry have a consistent structure, allowing readers to see how environmental conditions and biodiversity have changed through evolutionary time. Entries include: Acid rain and fog Biodiversity in the Jurassic period Darwin's finches Galápagos Islands Peter and Rosemary Grant Life in bogs Natural selection Population genetics Seedless plants Tropical rainforests and deforestation Alfred Russel Wallace.

Book Description
Islands have captured the imagination of scientists and the public for centuries—unique and rare environments, their isolation makes them natural laboratories for ecology and evolution. This authoritative, alphabetically arranged reference, featuring more than 200 succinct articles by leading scientists from around the world, provides broad coverage of all the island sciences. But what exactly is an island? The volume editors define it here as any discrete habitat isolated from other habitats by inhospitable surroundings. The Encyclopedia of Islands examines many such insular settings—oceanic and continental islands as well as places such as caves, mountaintops, and whale falls at the bottom of the ocean. This essential, one-stop resource, extensively illustrated with color photographs, clear maps, and graphics will introduce island science to a wide audience and spur further research on some of the planet's most fascinating habitats.
