Download or read book Phytochemical Methods written by Jeffrey B. Harborne and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: While there are many books available on methods of organic and biochemical analysis, the majority are either primarily concerned with the application of a particular technique (e.g. paper chromatography) or have been written for an audience of chemists or for biochemists work ing mainly with animaltissues. Thus, no simple guide to modern metho ds of plant analysis exists and the purpose of the present volume is to fill this gap. It is primarily intended for students in the plant sciences, who have a botanical or a general biological background. It should also be of value to students in biochemistry, pharmacognosy, food science and 'natural products' organic chemistry. Most books on chromatography, while admirably covering the needs of research workers, tend to overwhelm the student with long lists of solvent systems and spray reagents that can be applied to each class of organic constituent. The intention here is to simplify the situation by listing only a few specially recommended techniques that have wide currency in phytochemical laboratories. Sufficient details are provided to allow the student to use the techniques for themselves and most sections contain some introductory practical experiments which can be used in classwork.

Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2017-08-11 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Download or read book Useful Plants of Neotropical Origin written by Heinz Brücher and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with useful plants of neotropical origin, i.e., plants which have been cultivated in Southern and Central America as well as their wild relatives. Quite a number of these trees and bushes have "conquerred" the world as early as 400 years ago and are nowadays of utmost importance for feeding the increasing world population (e.g., potatoes). It has been estimated that about 150 such useful plants stem from the "New World." This book does not only describe the current theories about their domestication, cultivation, and evolution; it also discusses biotechnological methods for improving their productivity.

Download or read book Begomoviruses Occurrence and Management in Asia and Africa written by Sangeeta Saxena and published by Springer. This book was released on 2017-10-14 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Begomoviruses are one of the most interesting plant viruses to study for basic and applied research as they cause huge economic losses to agriculture industries and farmers all over the world. They belong to family Geminiviridae and are emergent plant viral pathogens which cause diseases in various crops in the tropical and subtropical regions. They are transmitted by the whitefly (B. tabaci) and have either one (monopartite DNA-A) or two (bipartite DNA-A and DNA-B) genomic components. DNA-A and DNA-B are of ~2600 - 2800 nucleotides each. A number of serious diseases of cultivated crops of the Fabaceae, Malvaceae, Solanaceae and Cucurbitaceae families are caused by Begomoviruses which are considered as threat to their cultivation in many countries. Accurate diagnosis is important for successful diseases management, since plants infected by Begomovirus do not recover, suffer serious yield losses and act as further sources of inoculum, which is then picked up and spread by their vector whitefly (B. tabaci). Reports of occurrence of new viruses and re-emergence of several known viruses in new niches have become regular event. In such a dynamic system, growth of several crop species relies on an accurate diagnosis, management and better understanding of the biology of the casual virus. This is crucial to evolve appropriate control practices and to prevent the virus infection. Researchers have achieved considerable progress in characterization, detection and management of virus on different crop species in the last decade. This book covers latest information in diagnosis of begomoviruses in the present scenario and explores the new vistas in the field of genomics and proteomics. Chapters in Section 1 illustrates the occurrence, genome organisation, transmission and diagnostics of begomoviruses. It also details the diseases caused by begomoviruses on different crops, detection techniques and management strategies in support of research findings by presentation of data, graphics, figures and tables. Section 2 is a chapterwise collection of occurrence, diversity and status of begomoviruses in Asian Africa counties where the diseases are most prevalent. This book will provide wide opportunity to the readers to have complete information and status of begomovirus in Asia and Africa. This will be useful resource for researchers and extension workers involved in the begomvirus disease diagnosis and molecular biology. Expert detection, accurate diagnosis and timely management play a significant role in keeping plants free from pathogens. In this book expert researchers share their research knowledge and literature which are vital towards the diagnosis of begomoviruses, addressing traditional plant pathology techniques as well as advanced molecular diagnostic approach. The book deals with the economically important crops including fruits, vegetables along with challenges in crop protection against diseases caused by begomovirus. This will be resourceful and handy for researcher, practitioners and also students.

Download or read book Behaviour and Ecology of Spiders written by Carmen Viera and published by Springer. This book was released on 2017-11-02 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the last few decades, arachnology in the Neotropical region has experienced a great development filling the knowledge gap in one of the most diverse regions of the world. Nevertheless, large geographical areas remain poorly sampled, especially within the Amazon, and new genera and species have been continuously discovered, even in urban areas. In congruence with the recent improvements in research, several aspects of the ecology, behaviour and natural history of spiders, such as interactions with other predators and parasitoids, social interactions, dispersal patterns, habitat requirements, mating behaviors, among others, are being carefully investigated. These recent contributions incorporate substantial information on the preexisting knowledge on these subjects every year. Our main objective with this book is to present a summary on these new researches and on the currently knowledge on the main subjects involved in the general theme, emphasizing the contribution of the rich fauna of the Neotropical region to the research of behaviour and ecology of the spiders.

Download or read book Wine Globalization written by Kym Anderson and published by Cambridge University Press. This book was released on 2018-02-22 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this anthology, editors Kym Anderson and Vicente Pinilla have gathered together some of the world's leading wine economists and economic historians to examine the development of national wine industries before and during the two waves of globalization. The empirically-based chapters analyze developments in all key wine-producing and consuming countries using a common methodology to explain long-term trends and cycles in wine production, consumption, and trade. The authors cover topics such as the role of new technologies, policies, and institutions, as well as exchange rate movements, international market developments, evolutions in grape varieties, and wine quality changes. The final chapter draws on an economic model of global wine markets, to project those markets to 2025 based on various assumptions about population and income growth, real exchange rates, and other factors. All authors of the book contributed to a unique global database of annual data back to the mid-nineteenth century which has been compiled by the book editors.

Download or read book The Names of Plants written by D. Gledhill and published by Cambridge University Press. This book was released on 1989-06-15 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides both a handy reference to the scientific names of plants and a clearly written account of the ways in which the naming of plants has changed with time and why these changes were necessary. It deals with the problems of using common names for plants against the historical background of our increasing discrimination of kinds of plants. It then goes on to consider landmarks in the standardization of both common and 'scientific' names and the development of internationally agreed principles governing the format and use of names in botany, sylviculture, agriculture and horticulture. From the alphabetical list the reader may interpret the scientific names of plants from any part of the world. For this second edition a number of changes and corrections in both parts have been made. The author has attempted to keep the first part acceptable to the amateur gardener by resisting a temptation to make it a definite guide to the International Code of Botanical Nomenclature. Others have done this already and with great clarity. Revision has allowed the inclusion of a brief comment on both synonymous and illegitimate botanical names and reference to recent attempts to accommodate the various traits and interests in the naming and names of cultivated plants.
