Jiuzhaigou was inscribed by UNESCO as a World Natural Heritage Site in 1992 for its lakes and waterfalls, colorful travertine landscape and unique cultural features. It belongs to Category V (protected landscape) in the IUCN system of categorizing protected areas. Diatoms, a large group of eukaryotic (with a membrane-bound nucleus) microalgae and the most common photosynthesizers (they produce their own food in the same way as plants), are the most important group for maintaining the unique travertine ecosystems in aquatic biotopes. Due to their great diversity and the expertise required for their identification, the diatoms of Jiuzhaigou have been rarely and incompletely studied.Atlas mainly provides a comprehensive diatom collection of Jiuzhaigou National Nature Reserve in the text form for diatom identification, with accompanying microscope images and alphabetical Latin names of the species list in the appendix. At the same time, it briefly introduces the basic information about Jiuzhaigou National Nature Reserve and general facts about diatoms to readers at home and abroad.This book can be used for reference and study by researchers and students in universities, institutes and other professional institutions, as well as by professionals engaged in lake biology and environmental protection.

Mosses are one of the most ancient terrestrial plants. Their small size and rich species have increased the difficulty in classification and thus there are still many taxonomic issues to be solved. The moss genus Ulota provides a good example in this regard. Engaged in the world taxonomic revision of this epiphytic moss for many years, the authors present the main conclusions of their research in this book. It not only introduces the taxonomy, phylogeny and evolution of Ulota, but also provides detailed and comprehensive information on the 50 species confirmed in this study, illustrated and accompanied by beautiful color photos, SEM images and distribution maps. This book brings together the latest findings of Ulota and useful reference for species classification for professionals and amateurs.

Upon its publication in 1957 A Glossary of Mycology was acclaimed by scientific and medical journals throughout the United States and Britain. The International Record of Medicine called it "a valuable reference book for every mycologist." Antibiotics and Chemotherapy recommended it as essential for all scientific libraries. The Bryologist said, "The authors are to be congratulated upon the wealth of information . . . the book is highly recommended in every respect." Nearly 7000 terms--technical terms and their derivations; common or popular, vernacular, and obsolete terms; terms used in the field of medical mycology and antibiotics; names of the originators of terms; folklore terms; and color terms--were covered by the original edition. Also included were terms which, though not strictly mycological, occur frequently in literature of particular interest to mycologists. This revision brings the work up to date with the considerable developments in the field since its first publication. Nearly 350 terms have been added, and new definitions for many of the original terms supplied. Excellent diagrammatic line drawings by Henry A. C. Jackson illustrate 191 of the terms.

"Fruit fly (Diptera: Tephritidae) pests have a profound impact on horticultural production and economy of many countries. It is fundamental to understand their biology and evaluate methods for their suppression, containment, or eradication. Area-Wide Management of Fruit Fly Pests comprises contributions from scientists from around the world on several species of tephritids working on diverse subjects with a focus on area-wide management of these pests. The first three sections of the book explore aspects of the biology, ecology, physiology, behavior, taxonomy, and morphology of fruit flies. The next two sections provide evidence on the efficacy of attractants, risk assessment, quarantine, and post-harvest control methods. The fifth and sixth sections examine biological control methods such as the Sterile Insect Technique and the use of natural enemies of fruit flies. The seventh section focuses on area-wide integrated pest management and action programs. Finally, the eighth section examines social, economic, and policy issues of action programs aimed at involving the wider community in the control of these pests and facilitate the development of control programs. Features: Presents information on the biology of tephritid flies. Provides knowledge on the use of natural enemies of fruit flies for their biological control. Includes research results on models and diets used for the Sterile Insect Technique. Reports developments on the chemical ecology of fruit flies that contribute to make control methods more specific and efficient. Reviews subjects such as Holistic Pest Management and Area-Wide Management Programs including social, economic, and policy issues in various countries"--

One of the world's leading evolutionary biologists here reexamines the evolutionary history of flowering plants. This important book is the first to interpret the phylogeny of flowering plants in the light of modern knowledge about genetics, developmental biology, and ecology. Mr. Stebbins is concerned with the evolution of genera, families, and other higher taxa; his analysis is based upon a unified theory that identifies the same fundamental processes at work in the origin of both species and the broader taxonomic categories. He shows, however, that subspecific evolution depends primarily on the natural selection of vegetative characters, whereas the emphasis at the transspecific level is on reproductive characters. Major changes in evolutionary direction are interpreted as resulting from an interaction of environmental change and the inherent capacity of the organism to alter preferentially in some ways and not in others. The author facilitates this discussion by examining reversibility in certain simple evolutionary trends. After reviewing basic principles and exploring major patterns of evolution in flowering plants, Mr. Stebbins turns to their actual history. On the basis of a detailed analysis he concludes that the most primitive forms are not represented in any extant category and are not found in the fossil record. His work gives definitive weight to the researches of others who have postulated a monophyletic origin of the angiosperms from a single, extinct group. Although this beautifully illustrated volume will prove indispensable to botanists, it will be of great interest also to any student of evolutionary theory, theoretical biology, and ecology.
