A comprehensive treatment of methodologies in the rapidly advancing field of marine benthic algal ecology.

Works cited in this useful survey are appropriate for students, librarians, and amateur and professional botanists. These encompass the plant kingdom in all its divisions and aspects, except those of agriculture, horticulture, and gardening. The majority of the annotations are for currently available in-print or electronic reference works. A comprehensive author/title and a separate subject index make locating specific entries simple. With materials ranging from those selected for the informed layperson to those for the specialist, this new edition reflects the momentous transition from print to electronic information resources. It is an appropriate purchase for public, college, university, and professional libraries.

Designed to serve as a primary reference source for researchers and students interested in expanding their research to consider a biopsychosocial approach, this book provides a thorough, state-of-the-art, and user-friendly coverage of basic techniques for measurement of physiological variables in health psychology research.

One of the primary references on analytical methods in soil science, Part 2 of the Methods series will be useful to all biogeoscientists, especially those with an interest in microbiology or bioremediation.

First published in 1988: This easy-to-read handbook provides a comprehensive review of the current knowledge on lichens. The structure of lichens and their dual nature is explained, as well as the physiology of interaction of the symbionts. The way lichens reproduce and their ecology is included, with methods for cultivating them and their isolated symbionts. Extremely useful as a text of lichenology, this handbook will benefit students of lichenology and allied fields, those interested in symbiotic associations and ecology, and teachers of biology, botany, and ecology courses.

The algae are a diverse group of organisms with forms that range in size from less than a micron in diameter to over ten meters in length. Small {laquo} 1 JLm diam) unicellular forms dominate the open waters of the oceans and large lakes. Large multicellular forms often form a large component of the autotrophic biomass of shallow waters at the periphery of lakes and oceans but have also been found on seamounts in clear open ocean waters at depths up to several hundred meters (Littler and Littler, 1985). Phytoplankton in the sea probably account for more than 50% of global photosynthesis, although there is considerable uncertainty about this estimate. In addition, many symbiotic associations between unicellu lar algae and heterotrophic or autotrophic organisms have been identi fied, and algae can be found in a diverse range of terrestrial environ ments, ranging from polar to desert regions. The most important common biochemical attribute that unites the algae is their ability to split water, producing molecular oxygen during photosynthesis and concomi tantly assimilating carbon dioxide. This attribute is shared with the terres trial plants, cyanobacteria and chloroxybacteria. Although vascular plants are excluded from this review, we employ a broad definition of algae that includes the photosynthetic, oxygenic procaryotes. Measurements of gas exchange are fundamental to most biochemical, physiological and ecological investigations of the algae.
