Download or read book Biology of the Chemotactic Response written by Society for General Microbiology. Symposium and published by Cambridge University Press. This book was released on 1990 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tendency of a living organism to move to a more favourable environment is a natural but complex reaction, involving the integration of sometimes conflicting environmental stimuli as well as a coordinated mechanical response. The response of motile, single cell organisms to environmental stimuli provides a useful model for understanding first of all how the environment is monitored and sensed, and secondly how this information is processed to result in an integrated and coordinated response. The volume looks at a large number of well-studied examples of the chemotactic response, in prokaryotes and eukaryotes, and casts new light on how cells process information and react to their environment. This fundamental response is of great importance in understanding one of the characteristic features of living organisms.

Download or read book Biology of the Chemotactic Response written by J. P. Armitage and published by Cambridge University Press. This book was released on 1991-02-21 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until recently the description of environmentally directed behavior had been at the phenomenological level. However, over the past decade, the mechanisms of movement, environmental sensing, and sensory transduction are being understood at the molecular level in both prokaryotic and eukaryotic single-celled organisms. This book covers the entire range of single-cell sensory transduction, from theories of gradient perception in prokaryotic and eukaryotic cells to the detailed molecular structure and function of sensory receptors, their respective secondary messengers, and the mechanisms of movement. The authors have also attempted to put the complex mechanisms of sensory transduction into the context of the organisms in their natural environment.

Download or read book Structure Function and Regulation of TOR complexes from Yeasts to Mammals written by and published by Academic Press. This book was released on 2010-03-13 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cell growth is highly regulated and is controlled by the TOR signaling network. Dysfunction of signaling pathways controlling cell growth results in cells of altered sizes and in turn causes developmental errors and a wide range of pathological conditions. An understanding of the TOR signaling network may lead to novel drugs for the treatment of, for example, cancer, diabetes, inflammation, muscle atrophy, learning disabilities, depression, obesity and aging. There has been an explosion of knowledge in this area in recent years and this volume provides an in-depth review of our current knowledge of TOR complexes by the leaders in the field. Contributions from leading authorities Informs and updates on all the latest developments in the field

Download or read book Dispersal Individual Movement and Spatial Ecology written by Mark A. Lewis and published by Springer. This book was released on 2013-03-21 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dispersal of plants and animals is one of the most fascinating subjects in ecology. It has long been recognized as an important factor affecting ecosystem dynamics. Dispersal is apparently a phenomenon of biological origin; however, because of its complexity, it cannot be studied comprehensively by biological methods alone. Deeper insights into dispersal properties and implications require interdisciplinary approaches involving biologists, ecologists and mathematicians. The purpose of this book is to provide a forum for researches with different backgrounds and expertise and to ensure further advances in the study of dispersal and spatial ecology. This book is unique in its attempt to give an overview of dispersal studies across different spatial scales, such as the scale of individual movement, the population scale and the scale of communities and ecosystems. It is written by top-level experts in the field of dispersal modeling and covers a wide range of problems ranging from the identification of Levy walks in animal movement to the implications of dispersal on an evolutionary timescale.

Download or read book Multitrophic Interactions in Terrestrial Systems written by A. C. Gange and published by Cambridge University Press. This book was released on 2002-08 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multitrophic interactions are now recognised as being of the utmost importance in understanding the complexity of the natural world. However, their complex nature had often been a barrier to their study as they require research teams composed of workers often with very disparate interests. This book therefore takes a multidisciplinary approach to complex interactions across many trophic levels and includes authors from disciplines as diverse as mycology, entomology, nematology, population ecology and theoretical ecology. Throughout, the direct and indirect interactions between organisms from different trophic levels are emphasised in comprehensive reviews, bringing a fresh, collaborative approach to community ecology. The book is ideal for those seeking an overview of our understanding of mulittrophic interactions as well as directions for future research.

Download or read book Sexual Reproduction in Animals and Plants written by Hitoshi Sawada and published by Springer. This book was released on 2014-02-07 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the International Symposium on the Mechanisms of Sexual Reproduction in Animals and Plants, where many plant and animal reproductive biologists gathered to discuss their recent progress in investigating the shared mechanisms and factors involved in sexual reproduction. This now is the first book that reviews recent progress in almost all fields of plant and animal fertilization. It was recently reported that the self-sterile mechanism of a hermaphroditic marine invertebrate (ascidian) is very similar to the self-incompatibility system in flowering plants. It was also found that a male factor expressed in the sperm cells of flowering plants is involved in gamete fusion not only of plants but also of animals and parasites. These discoveries have led to the consideration that the core mechanisms or factors involved in sexual reproduction may be shared by animals, plants and unicellular organisms. This valuable book is highly useful for reproductive biologists as well as for biological scientists outside this field in understanding the current progress of reproductive biology.
