Download or read book The Shoot Apical Meristem written by R. F. Lyndon and published by . This book was released on 1998 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: The shoot apex, although tiny and enclosed in the apical bud, forms the whole of the shoot system of plants and has a key role in producing leaves and flowers. An appreciation of how it functions is essential to an understanding of plant growth. In this book, the questions of the manner and the speed at which the shoot apex grows, and the likely cellular processes that are involved in the formation of leaves and flowers, are examined at the biochemical, physiological, biophysical, molecular, and genetic levels. This book is the only one currently available that is wholly devoted to the growth and physiology of the shoot apex and its key role in the formation of leaves and flowers.
Download or read book Biological Approaches and Evolutionary Trends in Plants written by Shoichi Kawano and published by Elsevier. This book was released on 2012-12-02 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological Approaches and Evolutionary Trends in Plants is a collection of papers presented at the Fourth International Symposium of Plant Biosystematics held on July 10-14, 1989 in Kyoto, Japan. Contributors, some are world's leading plant biologists, discuss the findings in evolutionary biology and issues in plant biosystematics in light of the evidence and ideas brought forward at various levels of biological organization, from molecule to cell, individual, population, species, and community levels. This volume is organized into four sections encompassing 22 chapters and begins with an overview of discoveries concerning parapatric differentiation of weed populations, including adaptive evolution in herbicide resistant biotypes and complex evolutionary patterns in weed-crop complexes of various groups. The next section explores molecular approaches in plant biosystematics, focusing on amino acid sequencing of proteins; restriction-site variations of cpDNA, mitDNA, rDNA, etc.; and chromosome-banding patterns revealed by differential staining. The discussion shifts to a wave of research in plant population biology and evolutionary ecology since the 1970s and its impact on biology and biosystematics. The book considers various aspects of reproductive biology and evolutionary changes in significant reproductive parameters and attempts to demographically quantify these parameters. The final chapter is devoted to the use of functional phylogenetic systematics for predictive ecology. This book will be of interest to plant biologists and scientists and researchers in fields such as biochemistry, botany, microbiology, ecology, and evolutionary biology.

Book excerpt: "The author begins by defining phenotypic plasticity and detailing its history, including important experiments and methods of statistical and graphical analysis. He then provides extended examples and discussion of the molecular basis of plasticity, the plasticity of development, the ecology of plastic responses, and the role of costs and constraints in the evolution of plasticity. A brief epilogue looks at how plasticity studies shed light on the nature/nurture debate in the popular media.".
Download or read book The Plant Cell Cycle written by Dirk Inzé and published by Springer Science & Business Media. This book was released on 2011-06-27 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the study of the plant cell cycle has become of major interest, not only to scientists working on cell division sensu strictu , but also to scientists dealing with plant hormones, development and environmental effects on growth. The book The Plant Cell Cycle is a very timely contribution to this exploding field. Outstanding contributors reviewed, not only knowledge on the most important classes of cell cycle regulators, but also summarized the various processes in which cell cycle control plays a pivotal role. The central role of the cell cycle makes this book an absolute must for plant molecular biologists.
Download or read book Arctic and Alpine Biodiversity Patterns Causes and Ecosystem Consequences written by F.Stuart III Chapin and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: As human populations expand and have increasing access to technol ogy, two general environmental concerns have arisen. First, human pop ulations are having increasing impact on the earth system, such that we are altering the biospheric carbon pools, basic processes of elemental cycling and the climate system of the earth. Because of time lags and feedbacks, these processes are not easily reversed. These alterations are occurring now more rapidly than at any time in the last several million years. Secondly, human activities are causing changes in the earth's biota that lead to species extinctions at a rate and magnitude rivaling those of past geologic extinction events. Although environmental change is potentially reversible at some time scales, the loss of species is irrevo cable. Changes in diversity at other scales are also cause for concern. Habitat fragmentation and declines in population sizes alter genetic di versity. Loss or introduction of new functional groups, such as nitro gen fixers or rodents onto islands can strongly alter ecosystem processes. Changes in landscape diversity through habitat modification and frag mentation alter the nature of processes within and among vegetation patches. Although both ecological changes altering the earth system and the loss of biotic diversity have been major sources of concern in recent years, these concerns have been largely independent, with little concern for the environmental causes the ecosystem consequences of changes in biodiversity. These two processes are clearly interrelated. Changes in ecological systems cause changes in diversity.
Download or read book Species Survival in Fragmented Landscapes written by J. Settele and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 670 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of isolation, area size, and habitat quality on the survival of animal and plant populations in the cultural landscape are central aspects of a research project started in Germany in 1993 (,Forschungsverbund, Isolation, FHichengroBe und BiotopquaIiHit', abbreviated to 'FIFB'). After a long period of preparation, scientists from seven univer sities and one research institution started to work within the frame of this project. Fund ing for four years was provided by the former German Federal Ministry of Research and Technology (BMFT), now the Ministry of Education and Research (BMBF). A strong focus of the project has been the improvement of the methodology for environmental impact assessments and the implementation of results into environmental planning. As there is a certain risk that national projects develop some kind of 'mental in breeding', it was decided to discuss concepts, methods, and first results with scientists of international reputation at a rather early stage of the project. For this purpose, an inter national workshop was held in the small village of Lubast, north of Leipzig (state of Saxony) in March 1995. 130 scientists from 10 nations met to discuss and debate issues surrounding habitat fragmentation for three days. Papers presented there formed the basis for this book. As discussions included general reviews as well as particular case studies, we decided to structure this book in a similar way. Consequently, a combination of broad and more general, review-like papers as well as original papers are presented.
Download or read book Sexual Reproduction of Tree Crops written by M. Sedgley and published by Academic Press. This book was released on 2013-10-22 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research into the reproductive biology of crop plants has expanded greatly in recent years and has lead to an increasing awareness of the importance of flowering, pollination, and fruit set in crop productivity. This book focuses specifically on tree cultivation. It deals with the basic biology of sexual reproduction and relates this to the practical aspects of tree crop breeding and orchard management for fruit and seed production, in both temperate and tropical species.It is aimed at both students and research scientists in horticulture, forestry, and pollination ecology as well as those working in tree breeding, tree cultivation, and orchard management. The conservation problems of rainforest regeneration in the tropics and subtropics and of changing land use priorities in Europe and North America also make this book of value to those concerned with tree species preservation and survival.
Download or read book Canada s Cold Environments written by Hugh M. French and published by McGill-Queen's Press - MQUP. This book was released on 1993-03-16 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low temperatures, wind-chill, snow, sea ice, and permafrost have been primary characteristics of Canada's northern and alpine environments during the past two million years. The evolution of Canada's cultural landscapes, the processes of settlement of rural areas, and the present interaction of Canadian industrial society with its biophysical environment are all deeply influenced, directly or indirectly, by the frigidity of the greater part of the country. The phenomenon of global warming, if it occurs, will lessen this coldness, but its impact on temperature extremes, sea ice regimes, vegetation, snow distribution, permafrost, glaciers, lakes, rivers, and mountain hazards are all the subject of intensive research -- the highlights of which are reviewed in Canada's Cold Environments. Eleven of Canada's leading geographers, geologists, and ecologists provide an authoritative yet readable scientific statement about the physical nature of Canada's coldness. They focus on the distinctive attributes of Canada's cold environments, their temporal and spatial variability, and the constraints that coldness places on human activity. The book is aimed at environmental scientists at all levels who need informed overviews of the substantive findings on a range of cold-related topics.
