Bacillus Subtilis

 

Academic Press, 1982.

ISBNs 9780122227011

Colección: ScienceDirect

Resumen (en inglés): The Molecular Biology of the Bacilli, Volume I: Bacillus subtilis focuses on areas of research traditionally investigated in Bacillus subtilis, as well as topics in which outstanding progress has been made. It discusses the sporulation, defective bacteriophage, and transformation of Bacillus subtilis.
Organized into 11 chapters, the book begins with the genetic map of Bacillus subtilis, followed by DNA replication and RNA polymerase of the said species. The book then describes the translational apparatus of Bacillus subtilis. It also explains the genetic transformation in Bacillus subtilis; the sporulation genes; the regulatory mechanisms in the development of lytic bacteriophages in this species; the temperate Bacillus subtilis phages; the specialized transduction in Bacillus subtilis; and molecular cloning in this organism. Lastly, the book considers the most economically important areas of the microbiological industry employing bacilli, including the production of enzymes, nucleosides, riboflavin, and preparations pathogenic to insects.
This book will be useful to scientists who are concerned with the use of Bacillus subtilis as a tool for the study of molecular biology and to those who wish to increase the medical, veterinary, and industrial usefulness of this and related organisms.

Bamboos of the World, The

Annotated Nomenclature and Literature of the Species and the Higher and Lower Taxa

 

Elsevier, 1999.

ISBNs 9780444500205

Colección: ScienceDirect

Resumen (en inglés): Bamboos constitute one of a few select categories of plants which are taxonomically related, very rich in species and of vital economic and ecological importance. Since the early 20th century the accepted number of species of bamboos, world wide, has tripled. However, until now information was scattered through numerous, often not easily available publications.

The Bamboos of the World, is the first comprehensive (taxonomic as well as horticultural) reference work that provides basic information on bamboos world wide, whether they are wild or cultivated, well-known or rather unknown. The work, based on bamboo literature, facilitates access to further data by citation and a comprehensive bibliography. Among the main data included are botanical names with synonyms, and geographical distribution of genera and species, varieties with their distinctive characters, common bamboo names, plant introductions to the West, plant size and uses. The distribution of genera is mapped.

The Bamboos of the World presents a wealth of essential information in an accessible and structured manner. It gives the opportunity to check under what names, and where, relevant information on any bamboo can be found. For the researcher with management and development interests it provides a convenient means of basing bamboo resource on a sound understanding of generic and species relationships, with names that appear in earlier literature put into context. The work should prove to be invaluable for those interested in the morphology, taxonomy, distribution and cultivation of bamboos. It should support botanical, forestry, horticultural and ecological research, training and resource management.

Beef Cattle Feeding and Nutrition

 

Academic Press, 1980.

ISBNs 9780125520508

Colección: ScienceDirect

Resumen (en inglés): Beef Cattle Feeding and Nutrition is the third in a series of books on animal feeding and nutrition. These books are designed to keep readers abreast of the rapid developments in feeding and nutrition. These developments have resulted in changes in diets, the use of new feed processing methods, improved use of by-product feeds, and more supplementation with minerals, vitamins, amino acids, and nonprotein nitrogen compounds.
The book is organized into four parts. Part I focuses on the nutrient requirements of beef cattle. Beginning with a review of rumen physiology and energy requirements, the remaining chapters discuss the vitamin, mineral, and protein, requirements of beef cattle. Part II on feedingstuffs includes studies on pasture and other forages; hay and haylage making; silage and crops for silage; and concentrates for beef cattle. Part III includes studies on breeding herd nutrition and management; and milk production and calf performance. Part IV on cattle finishing covers cattle finishing systems; feedlot disease; and economics of cattle feeding.

Behavior of Fish and Other Aquatic Animals, The

 

Academic Press, 1978.

ISBNs 9780125092500

Colección: ScienceDirect

Resumen (en inglés): The Behavior of Fish and Other Aquatic Animals provides a comprehensive discussion of the behavior of fish and other aquatic animals. It aims to fulfill the need for published materials that can responsibly depict the status quo of existing knowledge, and that can serve to educate the scientist seeking an organized presentation focused on biobehavioral issues and techniques.
The book begins by exploring symbiotic relationships in fishes that range from broad multispecific types that have little or no intimacy between symbionts to intimate mutualistic relationships. It then presents studies on the feasibility of using teleost fish as subjects in behavioral toxicology experiments; the visual behavior of fishes; the role of the teleost telencephalon in behavior; and the auditory systems of fishes. The remaining chapters cover the behavior of turtles in land, sea, and fresh waters; visually guided behavior in turtles; the gas bubble disease of fish; and the advantages and limitations of acoustic telemetry, which has been used to obtain data from animals ranging in size from hatchling sea turtles to large tuna and sharks.

Behavioral and Department Models

 

Academic Press, 1980.

ISBNs 9780127824017

Colección: ScienceDirect

Resumen (en inglés): Nematodes as Biological Models is two-volume treatise that provides a comprehensive reference source for research, in which free-living nematodes have been used to examine fundamental processes in genetics, development, nutrition, toxicology, pharmacology, and gerontology. The text emphasizes the use of Caenorhabditis elegans as a model in a variety of biological studies and also includes description of important studies utilizing other free-living nematodes as models.

Volume 1: Behavioral and Developmental Models covers cell lineages, muscle development, behavior, the nervous system, control mechanisms, and genetics, with the major emphasis on C. elegans. Significant contributions derived primarily from studies on the parasitic nematode Ascaris and the free-living nematode Panagrellus are also considered.

The second volume includes discussions on free-living nematodes as biological models for pharmacological and toxicant testing, and for studies on gerontology and nutrition. Several chapters in this volume also cover nematode physiology and morphology, which readers will find useful in understanding the subject matter.

The book is a masterful reference for students and lecturers in parasitology, zoology, physiology, and other related biological courses. Researchers and extended workers on nematology and related disciplines will also find this book invaluable.

Biochemistry and Physiology of Tetrahymena, The

 

Academic Press, 1972.

ISBNs 9780123483508

Colección: ScienceDirect

Resumen (en inglés): The Biochemistry and Physiology of Tetrahymena presents a review of the literature covering the physiology and biochemistry of the ciliate genus Tetrahymena, of which Tetrahymena pyriformis is the most studied species.
Organized into 10 parts, this book first provides basic information about Tetrahymena, which is found in almost any body of water and is so unusual that one can debate quite rationally as to whether it is an animal or a plant. Other chapters are restricted to specific subjects about this organism, namely, carbohydrate, lipid, energy, protein, amino acid, purine, pyrimidine, and nucleic acid metabolism. The organism’s biochemical genetics, vitamin and inorganic requirements, and evolution are also shown. This book also explores the effect of radiation, drugs, and hydrostatic pressure on Tetrahymena.
The documented information presented in this book will be sufficient to stimulate even more interest in the organism.
