Available in PDF, EPUB and Kindle. Book excerpt: Along the undisturbed shores, especially of the Mediterranean Sea and the European North Atlantic Ocean, is a quite widespread plant called Beta maritima by botanists, or more commonly sea beet. Nothing, for the inexperienced observer's eye, distinguishes it from surrounding wild vegetation. Despite its inconspicuous and nearly invisible flowers, the plant has had and will have invaluable economic and scientific importance. Indeed, according to Linnè, it is considered "the progenitor of the beet crops possibly born from Beta maritima in some foreign country". Recent molecular research confirmed this lineage. Selection applied after domestication has created many cultivated types with different destinations. The wild plant always has been harvested and used both for food and as a medicinal herb. Sea beet crosses easily with the cultivated types. This facilitates the transmission of genetic traits lost during domestication, which selection processes aimed only at features immediately useful to farmers and consumers may have depleted. Indeed, as with several crop wild relatives, Beta maritima has been successfully used to improve cultivated beet’s genetic resistances against many diseases and pests. In fact, sugar beet cultivation currently would be impossible in many countries without the recovery of traits preserved in the wild germplasm. Dr. Enrico Biancardi graduated from Bologna University. From 1977 until 2009, he was involved in sugar beet breeding activity by the Istituto Sperimentale per le Colture Industriali (ISCI) formerly Stazione Sperimentale di Bieticoltura (Rovigo, Italy), where he released rhizomania and cercospora resistant germplasm and collected seeds of Mediterranean sea beet populations as a genetic resource for breeding and ex situ conservation. Retired since 2009, he still collaborates with several working breeders, in particular, at the USDA Agricultural Research Stations, at the Chinese Academy of Agricultural Science (CAAS), and at the Athens University (AUA). He has edited books, books chapters and authored more than 150 papers. Dr. Lee Panella is a plant breeder and geneticist with the USDA-ARS at Fort Collins, Colorado. He earned his B.S. in Crop and Soil Science from Michigan State University, an M.S. in Plant Breeding from Texas A&M University, and a Ph.D. in genetics from the University of California at Davis. His research focus is developing disease resistant germplasm using sugar beet wild relatives. He is chairman of the USDA-ARS Sugar Beet Crop Germplasm Committee and has collected and worked extensively with sea beet. Dr. Robert T. Lewellen was raised on a ranch in Eastern Oregon and obtained a B.S. in Crop Science from Oregon State University followed by a Ph.D. from Montana State University in Genetics. From 1966 to 2008 he was a research geneticist for the USDA-ARS at Salinas, California, where he studied the genetics of sugar beet and as a plant breeder, often used sea beet as a genetic source to produce many pest and disease resistant sugar beet germplasm and parental lines, while authoring more than 100 publications.

Download or read book The pollination of cultivated plants A compendium for practitioners written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-10-15 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than twenty years ago, the Food and Agriculture Organization of the United Nations contributed to the growing recognition of the role of pollination in agricultural production, with the publication of “The Pollination of Cultivated Plants in the Tropics”. Since that time, the appreciation of pollinators has grown, alongside the realization that we stand to lose them. But our knowledge and understanding of crop pollination, pollinator biology, and best management practices has also expanded over this time. This volume is the second of two “compendiums for practitioners”, sharing expert knowledge on all dimensions of crop pollination in both temperate and tropical zones. The focus in this second volume is on management, study and research tools and techniques.

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 Sampling Methods in Soybean Entomology written by M. Kogan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects as a group occupy a middle ground in the biosphere between bacteria and viruses at one extreme, amphibians and mammals at the other. The size and gen eral nature of insects present special problems to the student of entomology. For example, many commercially available instruments are geared to measure in grams, while the forces commonly encountered in studying insects are in the mil ligram range. Therefore, techniques developed in the study of insects or in those fields concerned with the control of insect pests are often unique. Methods for measuring things are common to all sciences. Advances sometimes depend more on how something was done than on what was measured; indeed a given field often progresses from one technique to another as new methods are discovered, developed, and modified. Just as often, some of these techniques fmd their way into the classroom when the problems involved have been suffici ently ironed out to permit students to master the manipulations in a few labo ratory periods. Many specialized techniques are confined to one specific research laboratory. Although methods may be considered commonplace where they are used, in another context even the simplest procedures may save considerable time. It is the purpose of this series (1) to report new developments in methodology, (2) to reveal sources of groups who have dealt with and solved particular entomological problems, and (3) to describe experiments which might be applicable for use in biology laboratory courses.

Download or read book Plumes from Paradise written by Pamela Swadling and published by Sydney University Press. This book was released on 2019 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: The natural resources of New Guinea and nearby islands have attracted outsiders for at least 5000 years: spices, aromatic woods and barks, resins, plumes, sea slugs, shells and pearls all brought traders from distant markets. Among the most sought-after was the bird of paradise. Their magnificent plumes bedecked the hats of fashion-conscious women in Europe and America, provided regalia for the Kings of Nepal, and decorated the headdresses of Janissaries of the Ottoman Empire. Plumes from Paradise tells the story of this interaction, and of the economic, political, social and cultural consequence for the island's inhabitants. It traces 400 years of economic and political history, culminating in the 'plume boom' of the early part of the 20th century, when an unprecedented number of outsiders flocked to the island's coasts and hinterlands. The story teems with the variety of people involved: New Guineans, Indonesians, Chinese, Europeans, hunters, traders, natural historians and their collectors, officials, missionaries, planters, miners, adventurers of every kind. In the wings were the conservationists, whose efforts brought the slaughter of the plume boom to an end and ushered in an era of comparative isolation for the island that lasted until World War II.
Download or read book From Memory to Marble written by Elizabeth Rankin and published by Walter de Gruyter GmbH & Co KG. This book was released on 2020-02-10 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the first time, the 92-metre frieze of the Voortrekker Monument in Pretoria, one of the largest historical narratives in marble, has been made the subject of a book. The pictorial narrative of the Boer pioneers who conquered South Africa’s interior during the 'Great Trek' (1835-52) represents a crucial period of South Africa’s past. Conceptualising the frieze both reflected on and contributed to the country’s socio-political debates in the 1930s and 1940s when it was made. The book considers the active role the Monument played in the rise of Afrikaner nationalism and the development of apartheid, as well as its place in post-apartheid heritage. The frieze is unique in that it provides rare evidence of the complex processes followed in creating a major monument. Based on unpublished documents, drawings and models, these processes are unfolded step by step, from the earliest discussions of the purpose and content of the frieze, through all the stages of its design, to its shipping to post-war Italy to be copied into marble from Monte Altissimo, up to its final installation in the Monument. The book examines how visual representation transforms historical memory in what it chooses to recount, and the forms in which it is depicted. The second volume expands on the first, by investigating each of the twenty-seven scenes of the frieze in depth, providing new insights into not only the frieze, but also South Africa’s history. François van Schalkwyk of African Minds, co-publisher with De Gruyter writes: From Memory to Marble is an open access monograph in the true sense of the word. Both volumes of the digital version of the book are available in full and free of charge from the date of publication. This approach to publishing democratises access to the latest scholarly publications across the globe. At the same time, a book such as From Memory to Marble, with its unique and exquisite photographs of the frieze as well as its wealth of reproduced archival materials, demands reception of a more traditional kind, that is, on the printed page. For this reason, the book is likewise available in print as two separate volumes. The printed and digital books should not be seen as separate incarnations; each brings its own advantages, working together to extend the reach and utility of From Memory to Marble to a range of interested readers.
Download or read book Grassland Farming and Land Management Systems in Mountainous Regions written by European Grassland Federation. International Symposium and published by . This book was released on 2011 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mountainous regions, which cover nearly half of the continent’s area, are in many ways of vital importance for the European population. They supply much of the continent ́s water, are centres of biological and cultural biodiversity, provide various opportunities for recreation/ farmers. But mountainous regions are characterised by permanent natural handicaps due to topographic and climatic restrictions on economic and agricultural activity. Because of the geographical constraints to farming, work productivity is on average lower by 28% in mountain areas compared with less favoured areas, and by 40% compared with lowlands. Agriculture in mountainous regions can therefore, in general, not compete with agriculture in advantaged lowlands and, with very few exceptions, cannot hope to become competitive in adopting intensive models in response to the growing global competition.

Book excerpt: "Essential reading for anyone who wants to understand history – and then go out and change it." –President Barack Obama Nelson Mandela was one of the great moral and political leaders of his time: an international hero whose lifelong dedication to the fight against racial oppression in South Africa won him the Nobel Peace Prize and the presidency of his country. After his triumphant release in 1990 from more than a quarter-century of imprisonment, Mandela was at the center of the most compelling and inspiring political drama in the world. As president of the African National Congress and head of South Africa's antiapartheid movement, he was instrumental in moving the nation toward multiracial government and majority rule. He is still revered everywhere as a vital force in the fight for human rights and racial equality. Long Walk to Freedom is his moving and exhilarating autobiography, destined to take its place among the finest memoirs of history's greatest figures. Here for the first time, Nelson Rolihlahla Mandela told the extraordinary story of his life -- an epic of struggle, setback, renewed hope, and ultimate triumph. The book that inspired the major motion picture Mandela: Long Walk to Freedom.

Download or read book Biodiversity written by N. Biedinger and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodiversity, sometimes simply understood as "diversity of species", is a specific quality of life on our planet, the dimensions and importance of which have just lately been fully realized. Today we know that "biological diversity is a global asset of incalculable value to present and future generations" (Kofi Annan). Biodiversity is spread unequally over the world: in fact, the main share of biological resources worldwide is harboured predominantly by the so-called developing countries in the tropics and sub tropics. Therefore, Biodiversity - A Challenge for Development Research and Policy was chosen as the title for an international conference which was held in Bonn in 1997 as one of the first major events organized by the then newly established North-South Centre for Development Research (ZEF) at Rheinische Friedrich-Wilhelms-Universitat Bonn (Germany). Since the ZEF, founded by the Senate of the University of Bonn in 1995, has played a central role in turning Bonn into a centre for international cooperation and North-South dialogue. The Centre is a product of the Bonn Berlin agreement of July 1994 which was adopted to offset the effects caused by the Parliament and much of the Government moving to Berlin. It fits in well with the double strategy to strengthen Bonn's position as an interna tional science arena and as an eminent place for development policy and the national and supranational agencies dealing with this issue.
Download or read book Human Behavior and Environment written by Irwin Altman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers comprising this second volume of Human Behavior and the Environment represent, as do their predecessors, a cross section of current work in the broad area of problems dealing with interrelation ships between the physical environment and human behavior, at both the individual and the aggregate levels. Considering the two volumes as a unit, we have included papers covering a broad spectrum of problems ranging from the theoretical to the applied, and from the disciplinary-based to the interdisciplinary and professional. Approxi mately half of the papers are written by psychologists, with the remainder coming, in part, from such other disciplines as sociology, geography, and from such diverse applied and professional fields as natural recreation, landscape architecture, urban planning, and opera tions research. The volumes thus provide an overview of work on current topical problems. Yet, as the field is developing, specialization is inevitably increasing apace, and the editors as well as the publisher have become convinced of the desirability for futu're volumes in this series to be organized along topical lines, with successive volumes devoted to different aspects of this rather sprawling field. Thus, Volume 3, currently in the planning stage, will be devoted exclusively to the interaction of children with the physical environment, considered from diverse viewpoints, again including authors from diverse fields of specialization.
