Between Pacific Tides is a book for all who find the shore a place of excitement, wonder, and beauty, and an unsurpassed introductory text for both students and professionals.This book describes the habits and habitats of the animals that live in one of the most prolific life zones of the world--the rocky shores and tide pools of the Pacific Coast of the United States. The intricate and fascinating life processes of these creatures are described with affectionate care. The animals are grouped according to their most characteristic habitat, whether rocky shore, sandy beach, mud flat, or wharf piling, and the authors discuss their life history, physiology, and community relations, and the influence of wave shock and shifting tide level.Though the basic purpose and structure--and much of the text--of the book remain the same, content has been increased by about 20 percent; a multitude of changes and additios has been made in the text; the Annotated Systematic Index and General Bibliography have been updated and greatly expanded (now almost 2,300 entries); more than 200 new photographs and drawings have been incorporated; and an entirely new chapter has been added--a topical presentation of the several factors influencing distribution of organisms along the shore. This edition also includes John Steinbeck's Foreword to the 1948 edition.

    Numerical problems throughout the text enable readers to test theirgrowing mastery of the subject.The major topics are population genetics, population and community ecology, and species equilibrium theory. Building from basic principles to advanced topics, the Primer fills a gap between introductory biology texts and advanced works in population biology. It can serve as a primary textbook forelementary courses in population biology. Or, in courses on genetics, evolution and ecology--where there is a need for all students to start at a reasonably high level of competence--it can serve as a supplementary text.The Primer introduces many advanced topics at the elementary level without loss of rigor: genetic drift, measurement of rates of evolution, competition theory, reproductive value, and the theory of species equilibrium.

    With full-color pictures and readable text, this guide identifies representative species and describes:Their characteristics and habitsGrowth, courtship and enemiesWhere they are foundIncludes information on poisonous species and how to collect, preserve, and raise spiders.

    The material covered and the time allotted to such courses varies considerably, and the illustrations are therefore designed to enable the instructor to point out the important features of areas which cannot be dissected in detail by every student.
