Science fairs, clubs, and talent searches are familiar fixtures in American education, yet little is known about why they began and grew in popularity. In Science Education and Citizenship, Sevan G. Terzian traces the civic purposes of these extracurricular programs for youth over four decades in the early to mid-twentieth century. He argues that Americans' mobilization for World War Two reoriented these educational activities from scientific literacy to national defense a shift that persisted in the ensuing atomic age and has left a lasting legacy in American science education.

This volume serves to challenge the conventional views of the relationship between health, disease, and iron; of the symptomatic role of low iron levels; of cultural imperatives related to diet, such as daily meat intake; and of prescribed iron fortification. The contributors are leading researchers in ethnography, archaeology, physical anthropology, microbiology, and medicine.

This book is intended to provide consolidated information on citrus breeding in the era of biotechnology, which is likely to hasten the pace of variety development aimed at resolving the problems faced by grove owners growing currently available cultivars. The subjects covered are focused on citrus while providing information equally useful to the breeders of other tree crops. It will also help students of genetic and breeding identify appropriate applications of biotechnology in citrus breeding. While providing information on future avenues, it also reviews the past progress and achievements ensuring continuity of the subject. Several chapters include protocols for novel techniques that should facilitate their broader application by citrus breeders.

Publisher Description

Studies with the foraminiferida have often been hindered by widely scattered, inaccessible sources. This two-volume reference (text in one volume, plates in the other) examines 3,568 of the world's generic taxa, representing all geologic ages. Covering twice the number of genera as any other available reference, it is by far the most complete source on the foraminiferida.

Straminipilous Fungi presents a critical comparative review of the morphology and ultrastructure, morphogenesis, cytology, molecular biology and evolution of the biflagellate fungi. These organisms encompass the fungi formerly called oomycetes; taxonomically related heterotrophs studied by mycologists; plasmodiophorids and other heterotrophs. Appropriate comparisons are made with chromophyte algae, marine heterotrophs and chytridiaceous fungi. Little-known taxa which have been referred to the various orders of flagellate fungi are also listed together with citations. A new hierarchical classification is presented which is supported by systematic accounts and synoptic keys. Dichotomous keys based on habitat and habit are given to all known species of lagenidiaceous fungi, labyrinthulids and plasmodiophorids. A unique `one stop' reference resource for plant pathologists is provided by the binominal lists, including host-related lists for the downy mildews. The book, including ca 4000 references, is a major text for post-graduate and research workers, particularly freshwater and marine biologists, soil ecologists and plant pathologists.

The Fourth Edition of The Light and Smith Manual continues a sixty-five-year tradition of providing to both students and professionals an indispensable, comprehensive, and authoritative guide to Pacific coast marine invertebrates of coastal waters, rocky shores, sandy beaches, tidal mud flats, salt marshes, and floats and docks. This classic and unparalleled reference has been newly expanded to include all common and many rare species from Point Conception, California, to the Columbia River, one of the most studied areas in the world for marine invertebrates. In addition, although focused on the central and northern California and Oregon coasts, this encyclopedic source is useful for anyone working in North American coastal ecosystems, from Alaska to Mexico. More than one hundred scholars have provided new keys, illustrations, and annotated species lists for over 3,500 species of intertidal and many shallow water marine organisms ranging from protozoans to sea squirts. This expanded volume covers sponges, sea anemones, hydroids, jellyfish, flatworms, polychaetes, amphipods, crabs, insects, snails, clams, chitons, and scores of other important groups. The Fourth Edition also features introductory chapters on marine habitats and biogeography, interstitial marine life, and intertidal parasites, as well as expanded treatments of common planktonic organisms likely to be encountered in near-to-shore shallow waters.
