This book was released on 2012-12-06 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: The expression of many bacterial genes adapts itself in an almost in stantaneous and reversible way to specific environmental changes. More specifically, the concentration of a number of metabolites, a function of the amounts of enzymes involved in their synthesis or degradation, in turn retroacts on the rate of synthesis of these enzymes. The genetic bases for this regulation were established by JACOB and MONOD (1961). These authors also showed how the known elements of these regulatory mechanisms could be connected into a wide variety of circuits endowed with any desired degree of stability, in order to account for essentially irreversible processes like differentiation (MONOD and JACOB, 1961). The general principles used by JACOB and MONOD in their study of negative regulation were extended to positive regulation by ENGLESBERG et al. (1965). An independent approach permitted the discovery of positive controls in temperate bacteriophages (see below, III). Each control operation is mediated by a pair of complementary genetic elements (hereafter called "control cell"): a control gene which produces a l control (or regulator) protein and a control site which is the target for the regulator protein. Negative control means that the control protein (repressor) prevents gene expression. One deals with positive control when the control protein (activator) is necessary for this expression. It has become apparent that, as initially postulated by JACOB and MONOD, control of gene expression operates, at least to a large extent, at the transcriptional level.

Download or read book The Pantanal of Mato Grosso Brazil written by F.D. Por and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until now there has never been a monograph devoted to the Pantanal, the world's largest wetland. The subject has received scant attention in the international literature, so a number of scattered Portuguese papers are reviewed for an English-language readership. The book presents a broad treatment of the Pantanal, ranging from geology to flora, fauna, and the human presence. The publication of this book is most timely, and will be of crucial importance in decisions affecting the ambitious project for a second South American inland Waterway.

Download or read book Lake Titicaca written by C. Dejoux and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Titicaca, because of its area and volume and its situation at high attitude within the tropics, is a unique hydrological site in the world. It should be noted that it stands at the transition point between two very distinct geographical regions: the desert fringe of the Pacific coast to the west and the great Amazonian forest extending to the Atlantic coast to the east. Many scientists have been attracted to the lake in the past because of its unusual limnological features. In this book the editors have compiled an exhaustive review of current knowledge from the existing literature and from the results of more recent observations. It is certain that this book will become the essential reference work for scientists wanting to make progress in revealing the lake's secrets. It can be stated unequivocally that this work constitutes a complete review of the present state of knowledge on Lake Titicaca and that it provides the latest results of research on this habitat.
Download or read book Biogeography and Ecology of Turkmenistan written by V. Fet and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 654 pages. Available in PDF, EPUB and Kindle. Book excerpt: remnants of gene pools of these species. Badghyz Natural Reserve, established in 1941, became a refuge for the last existing population of the Turkmen onager (Equus hemionus onager) and a unique pistachio woodland. A new generation oflocal Turkmen scientists, many of whom were trained by the Russian researchers in the graduate schools of Moscow and Leningrad arose from the 1930s through the 1950s. The Turkmen Academy of Sciences and its journal, Proceedings (including the monthly biological series), served to record the results of diverse biological studies in the republic. While basic science in the Middle Asian republics rather gained from the Russian "colonial" influence, natural resources, in contrast, were severely damaged by the Soviet way of handling the economy and social issues. Severe environmental problems have been inherited by the now independent Turkmenistan, including overgrazed desert pastures, deforested mountains, depleted water resources, accumulated pesticides in cotton fields, declining populations of endangered species of animals and plants, and - worst of al- progressing, human-caused desertification (Kharin this volume). In order to approach a solution to these problems, scientists and officials in the republic will need the close attention and help of the international scientific community.

Download or read book Lough Neagh written by R.B. Wood and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 533 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lough Neagh is the largest lake in the British Isles. It covers an area of 383 km2 being 30 km along its longest axis. From pre-historic times the lake and its rivers influenced the settlements of man in the role of a fishery and communication link with the interior of Ireland. Ireland's first canal, completed in 1787, linked the small but significant coal deposits of Tyrone to Dublin by way of the lough and later the Lagen Canal became an important commercial route to the new city of Belfast. Today, only sand barge transport persists but the lough supports Europe's largest eel fishery and provides commercial salmon, trout and perch catches, besides acting as an important centre for recreational pursuits. Increasingly it has become the major water resource for Northern Ireland supplying much of the demand for the heavily populated Belfast area. Biologically the lough is rich, sustaining enormous invertebrate populations of, for example, chironomids and gammarids alongside the comparatively exotic glacial relict, Mysis relicta. Its bird life makes the lough an area of very special conservation interest as a Ramsar site. The book describes the basic ecology of the lough with particular emphasis on both the interaction of the physical, chemical and biological components and the role of ecology in resource management. Extensive recent researches are set in geological, geographical and historical context and together with palaeolimnological studies of the sediments are used to trace major changes in the ecology of the lough under man's influence, especially in the past 100 years.

Download or read book Diagnostic Bacteriology Protocols written by Jenny Howard and published by Springer Science & Business Media. This book was released on 2008-02-03 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enhanced public awareness of microbiological issues and increased governmental regulation have ensured that microbiology and bacteriology remain important, from the academic laboratory to a broad range of indus trial environments. Since the techniques used in bacteriology vary widely and have advanced rapidly of late, it has become increasingly desirable to gather a collection of up-to-date protocols from a comprehensive range of disciplines into a single volume. Diagnostic Bacteriology Protocols thus aims to provide a wide variety of up-to-date protocols for the identification and differentiation of bacteria from pure or mixed cultures, and for the study of bacteria at the genus through to subspecies levels. In addition, we aim to provide methods covering a range of complexities, some requiring little or no special equipment, others exploiting recent advances in sophisticated instrumentation or novel nucleic acid-based technology. We also present techniques to study a variety of aspects of bacteria—from the features of whole cells and their growth, through their enzyme activities and structural components, to nucleic ac- based analysis.
Download or read book Salmonella written by Bassam Annous and published by BoD – Books on Demand. This book was released on 2012-07-18 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of Salmonella in swine in 1885 marked the beginning of intense efforts to control salmonellae that have continued for the past 127 years. The majority of foodborne outbreaks are caused by only a few of the 2500+ known serovars. While progress has been made on many fronts, salmonellosis has yet to be eliminated in either developed or in developing nations. This work represents the collective contributions of authors from all around the world. Chapters in this book address a wide array of topics related to understanding and controlling this pathogen, including: Salmonella as studied in the environment, air and in food products; virulence and pathogenicity; control by bacteriophages and other antimicrobials; bacterial adaptation; etc.
