Available in PDF, EPUB and Kindle. Book excerpt: This volume was created initially from a symposium of the same name presented at the International Primatological Society's XVIII Congress in Adelaide. South Australia. 6-12 January 2000. Many of the authors who have contributed to this text could not attend the symposium. so this has become another vehicle for the rapidly growing discipline of Fragmentation Science among primatologists. Fragmentation has quickly become a field separate from general ecology. which underscores the severity of the situation since we as a planet are rapidly losing habitat of all types to human disturbance. Getting ecologists. particularly primatologists. to admit that they study in fragments is not easy. In the field of primatology. one studies many things. but rarely do those things (genetics. behavior. population dynamics) get called out as studies in fragmentation. For some reason "fragmentation primatologists" fear that our work is somehow "not as good" as those who study in continuous habitat. We worry that perhaps our subjects are not demonstrating as robust behaviors as they "should" given fragmented or disturbed habitat conditions. I had a colleague openly state that she did not work in fragmented forests. that she merely studied behavior when it was clear that her study sites. everyone of them. was isolated habitat. Our desire to be just another link in the data chain for wild primates is so strong that it makes us deny what kinds of habitats we are working in. However.

Download or read book The Social Metabolism written by Manuel González de Molina and published by Springer. This book was released on 2014-06-30 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over this last decade, the concept of Social Metabolism has gained prestige as a theoretical instrument for the required analysis, to such an extent that there are now dozens of researchers, hundreds of articles and several books that have adopted and use this concept. However, there is a great deal of variety in terms of definitions and interpretations, as well as different methodologies around this concept, which prevents the consolidation of a unified field of new knowledge. The fundamental aim of the book is to conduct a review of the past and present usage of the concept of social metabolism, its origins and history, as well as the main currents or schools that exist around this concept. At the same time, the reviews and discussions included are used by the authors as starting points to draw conclusions and propose a theory of socio-ecological transformations. The theoretical and methodological innovations of this book include a distinction of two types of metabolic processes: tangible and intangible; the analysis of the social metabolism at different scales (in space and time) and a theory of socio-ecological change overcoming the merely “systemic” or “cybernetic” nature of conventional approaches, giving special protagonism to collective action.

Download or read book Biodeterioration 7 written by D. R. Houghton and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 865 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the magnificent response to the call for papers for the 7th International Biodeterioration Symposium held at Cambridge, UK, some difficulties have been experienced in the editing of these proceedings. The numbers of papers submitted exceeded expectation and because of this it has been necessary to accommodate those not actually in the proceedings into the International Biodeterioration journal. A small number of papers were not suitable for publication and were therefore eliminated. Many authors disregarded the guidelines laid down for the length of submitted papers. However, every attempt has been made to accommodate the maximum number of contributions in the proceedings. The original selection included those which most nearly conformed to the length requirement. Even so this has meant, in many cases, cutting down the text, eliminating tables and/or illustrations and pruning the reference list. When references have been trimmed a note has been included to the effect that an extended list may be obtained from the author/senior author. Where it was not possible to carry out these procedures without seriously altering the text and the import of the paper they have been included amongst those to be published in the journal International Biodeterioration. The exceptions to the procedures outlined above are the invited review papers which have been presented in full. Happily, the authors have been conscientious in keeping to the guidelines laid down for these contributions.

Download or read book Banana Genomics and Transgenic Approaches for Genetic Improvement written by Sukhada Mohandas and published by Springer. This book was released on 2016-09-08 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bananas and plantains are among the most important food and cash crops in the world. They are cultivated in more than 135 countries, across the tropics and subtropics, with an annual global production of ca. 130 million metric tonnes. Though bananas are one of the most important components of food security in many developing countries, banana production is threatened by both abiotic and biotic stresses. These include a wide range of diseases and pests, such as bunchy top virus, burrowing nematodes, black Sigatoka or black leaf streak, Fusarium wilt, etc. In recent years, considerable progress has been made and several biotechnological and genomic tools have been employed to help understand and unravel the mysterious banana genome. Molecular and genomic studies have helped to decipher the Musa genome and its evolution. Genetic linkage map and whole genome sequencing of both Musa acuminata and Musa balbisiana (progenitors of cultivated banana) have completely changed the way of thinking and the approach on banana crop improvement. Whole-genome sequencing has helped to improve the selection of quantitative traits such as yield, as well as the selection of optimal parents for developing required hybrids in breeding programs. Gene isolation and the analysis of mutants have helped in the characterization of genes of agronomic value and the associated regulatory sequences. With the advent of molecular markers and new statistical tools, it is now possible to measure the diversity, identify genes and useful alleles linked to important agronomic traits. Further these alleles can be incorporated into cultivars through marker assisted selection or through transgenic approach. Transgenic approaches are potential tools for direct transfer of these genes into popular cultivars, which are generally not amenable for conventional breeding techniques, in specific with crops such as bananas which are sterile, triploid and heterozygous thereby making it difficult to reconstruct the recurrent genotypes in banana. Transgenic techniques thus have helped overcome the difficulty of working with sterile, triploid banana crop. In the last five years, enormous amount of new information and techniques have been generated for banana. A comprehensive book entitled “Banana: Genomics and Transgenic Approaches for Genetic improvement” on banana genomics, latest transgenic technologies and tools available for improved crop development in banana will address all these requirements.

This book was released on 2012-12-06 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: The preface of a book often provides a convenient place in which the author can tender his apologies for any inadequacies and affords him the facility to excuse himself by reminding the reader that his art is long but life, or at least the portion of it in which he has the opportunity for writing books, is short. I, too, am deeply conscious that I have undertaken a task which I could not hope to complete to my own satisfaction but I offer, in self defence, the observation that, inadequate though it is, there is no other book extant, so far as I am aware, which provides the information contained herein within the covers of a single volume. Often during the last decade, in discharging my responsibilities for the environmental aspects of the water authority's operations and works, I should have been deeply grateful to have had access to a compendium such as this. The lack of a convenient source of data made me aware of the need which I have attempted to fill and in doing so I have drawn on my experiences of the kinds of problem which are presented to biologists in the water industry. The maxim 'half a loaf is better than none' seems particularly apt in this context.

Download or read book Xenotransplantation written by Institute of Medicine and published by National Academies Press. This book was released on 1996-07-12 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Xenotransplantation involves the transplantation of cells, tissues, and whole organs from one species to another. Interest in animal-to-human xenotransplants has been spurred by the continuing shortage of donated human organs and by advances in knowledge concerning the biology of organ and tissue rejection. The scientific advances and promise, however, raise complex questions that must be addressed. This book considers the scientific and medical feasibility of xenotransplantation and explores the ethical and public policy issues surrounding the possibility of renewed clinical trials. The volume focuses on the science base of xenotransplantation, public health risks of infectious disease transmission, and ethical and public policy issues, including the views of patients and their families.

Download or read book Temperate Agroforestry Systems written by Andrew M Gordon and published by CABI. This book was released on 2018-03-07 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic animal production has increased rapidly in recent years to keep up with the increasing consumer demand for organic meats. There are many guidelines and restrictions on what should go into the feedstuffs of organically farmed animals, from which difficulties arise when trying to ensure a well-balanced, nutritious diet without the use of any supplements. The book has been completely updated and revised to address how to formulate organic diets in situations where there is a declining supply of organic feed, as well as the feasibility of utilizing novel feedstuffs and their acceptability by consumers of organic meat products. Including the experiences of producers in relation to appropriate breeds and production systems for forage-based organic production, this book is an important read for researchers and students of organic food animal production, veterinary sciences and food; as well as food industry personnel and organic farmers.

Download or read book The Andes written by Axel Borsdorf and published by Springer. This book was released on 2015-03-12 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Andes are attracting global interest again: they hold valuable mineral resources, tourists appreciate their great natural beauty and the diversity of indigenous cultures, climbers scale rock and ice faces, while many others are intrigued by regional political developments, such as the Bolivarian revolution in Venezuela or the almost unfettered hegemony of the neoliberal economic model in Chile. This volume is the first attempt for decades to present a complete overview of the longest mountain chain on the planet – a region of remarkable climatic, floristic and geologic diversity, where advanced civilization developed well before the arrival of the Spanish. Today the Andes continue to be characterized by their ethnic, demographic, cultural and economic diversity, as well as by the disparity of local socioeconomic groups. The Andean countries pursue a wide range of approaches to tackle the challenges of making the best use of their natural and cultural potential without damaging their ecological basis, as well as to overcome economic disparity and foster social cohesion. This book provides insights into this unique region and its most pressing issues, complemented by a wealth of pictures and comprehensive diagrams, which, in sum, help to better understand these fascinating mountains.
