Technology, Engineering & AgricultureJanuary 2024Vegetable Seeds
Production and Technology
by Gregory E Welbaum
Most food and fiber crops are produced from seed. This means that the world's population is dependent on annual seed production for its food supply. Vegetable seed production is much different and more challenging than production of grain crops. This book explains the biology and technology behind producing, maintaining, and enhancing the quality of vegetable seeds from breeding through to the marketed product. It begins with six chapters on a broad range of seed-related topics: the importance of seeds, reproductive biology of plants, genetic improvement strategies, quality assurance of seed production, post-harvest seed enhancement, and organic production. The remaining chapters cover seed production in eleven important vegetable families. Each chapter provides a description of the botany, types and cultivars, genetic improvement, pollination, soil fertility management, pest management, crop production, harvesting, post-harvest handling, and seed yields. The aim of this book is to educate how to produce high-quality vegetable seeds. Incorporating both current methodologies and recent research results, it is suitable for students, researchers, and professionals in the seed industry.

Literature & Literary StudiesOctober 2017Botany, sexuality and women's writing, 1760–1830
From modest shoot to forward plant
by Sam George
In this fascinating study, Samantha George explores the cultivation of the female mind and the feminised discourse of botanical literature in eighteenth-century Britain. In particular, she discusses British women's engagement with the Swedish botanist, Carl Linnaeus, and his unsettling discovery of plant sexuality. Previously ignored primary texts of an extraordinary nature are rescued from obscurity and assigned a proper place in the histories of science, eighteenth-century literature, and women's writing. The result is groundbreaking: the author explores nationality and sexuality debates in relation to botany and charts the appearance of a new literary stereotype, the sexually precocious female botanist. She uncovers an anonymous poem on Linnaean botany, handwritten in the eighteenth century, and subsequently traces the development of a new genre of women's writing - the botanical poem with scientific notes. The book is indispensable reading for all scholars of the eighteenth century, especially those interested in Romantic women's writing, or the relationship between literature and science.

June 2024Plant Nematology
by Roland N Perry, Maurice Moens, John T Jones
Plant-parasitic nematodes are a major threat to crop production in all countries, and identification of nematodes and knowledge of their biology is of paramount importance. Providing a broad introduction to nematodes as plant parasites, this book begins by describing nematodes by genera, and then builds on this foundation to detail nematode biology and pest management, including resistance, and biological and chemical control. This 3rd edition is updated to address advances in our knowledge of plant-parasitic nematodes, particularly concerning the molecular aspects of host-parasite relationships, including the application of genomics to nematode biology. Changes in control and management strategies are also covered. The influence of climate change on plant-parasitic nematodes is addressed in a new chapter on ecology. Primarily aimed at students (MSc and PhD), this book is also invaluable for researchers and lecturers in nematology, plant pathology and parasitology, advisory and quarantine services, and crop protection scientists.

Plant ecologyDecember 2016Plant Biodiversity
Monitoring, Assessment and Conservation
by Edited by Abid A Ansari, Sarvajeet Singh Gill
Plants are important components to the ecosystem. They are the base of the food chain and play a significant role in energy flow and biogeochemical cycling of nutrients between terrestrial and aquatic ecosystems. They must constantly fight against the environmental modifications, however, that threaten to cause global species extinction and habitat destruction. A new multidisciplinary science has evolved to deal with the crises confronting biological diversity. It has two goals: first, to investigate human impacts on biological diversity and second, to develop practical approaches to prevent extinction of species. This book is a practical update on our knowledge on monitoring, assessment and conservation of plant biodiversity in aquatic and terrestrial ecosystems and related fields. It includes a general overview of plant biodiversity, investigates a wealth of factors affecting and hindering plant biodiversity before exploring in depth methods of monitoring, assessing and conserving our plant species. Globally relevant, this book is a valuable resource for all researchers, professionals and students of botany and plant biodiversity studies.

Geography & the EnvironmentOctober 2020Plant Invasions
The Role of Biotic Interactions
by Anna Traveset, David M Richardson
Despite many books on plant invasions, none has focused on the role of species interactions. This book is a comprehensive overview of how plant invasions are mediated by varied species interactions and how such invasions influence this important component of biodiversity which involves the interactions (the 'glue') among a community's species. Besides highlighting relevant findings, the book digs deeply into new methodologies to understand species interactions in plant invasions and how this can improve management of invaded communities. The book covers: - Main theories/hypotheses in plant invasion ecology that invoke species interactions - Plant invasions promoted by mutualistic interactions and release from enemies - Antagonistic interactions preventing or hindering plant invasions - Consequences of plant invasions on native species interactions and ecosystem functioning - The interaction network approach to understanding plant invasions - Importance of considering species interactions in managing plant invasions Future avenues of research are highlighted in a final chapter. Table of contents Part I: Background Chapter 1: Plant invasions: the role of biotic interactions – An overview Chapter 2: The role of biotic interactions in invasion ecology: theories and hypotheses Part II: Positive and negative interactions in the soil Chapter 3: Soil biota and non-native plant invasions Part III: Mutualistic interactions that promote plant invasions Chapter 4: Pollination interactions promoting plant invasions- Chapter 5: Seed dispersal interactions promoting plant invasions Chapter 6: Ungulates as dispersal vectors of non-native plants Chapter 7: The role of plant-plant facilitation in non-native plant invasions Chapter 8: How direct and indirect non-native interactions can promote plant invasions, lead to invasional meltdown, and inform management decisions Part IV: Antagonistic interactions that hinder plant invasions Chapter 9: Biotic resistance to plant invasions Chapter 10: EICA 2.0: A general model of enemy release and defence in plant and animal invasions Chapter 11: The role of pathogens in plant invasions Chapter 12: Direct and indirect effects of herbivores influencing plant invasions Part V: Consequences of plant invasions for biotic interactions among native species Chapter 13: Impacts of non-native plants on plant-pollinator interactions Chapter 14: The effect of non-native plant invasions on seed dispersal of native plants Chapter 15: Allelopathic disruptions of biotic interactions due to non-native plants Chapter 16: Competition between native and non-native plants Chapter 17: Indirect biotic interactions between non-native plants and native plants and animals Part VI: Novel techniques and experimental approaches in the study of plant invasions Chapter 18: How a network approach has advanced the field of plant invasion ecology Chapter 19: Molecular ecology of plant-microbial interactions during invasions: progress and challenges Part VII: Biotic interactions and the management of ecosystems invaded by non-native plants Chapter 20: How can progress in the understanding of antagonistic interactions be applied to improve biological control of plant invasions? Chapter 21: Restoration of pollination interactions in communities invaded by non-native plants Chapter 22: Restoration of seed dispersal interactions in communities invaded by non-native plants Chapter 23: Multiple feedbacks due to biotic interactions across trophic levels can lead to persistent novel conditions that hinder restoration

January 2018Plant Diversity, Second Edition
by J. Phil Gibson and Terri R. Gibson, Series Editor: William G. Hopkins
Plants feed us, clothe us, provide us with the oxygen we breathe, and buffer our environment against change. In short, plants make life possible. Yet scientists estimate that more than 10 percent of the world's approximately 300,000 plant species are at risk of extinction, and huge swaths of tropical forests and other plant communities are being decimated daily. Plant Diversity, Second Edition surveys the world's plant diversity, from green algae through flowering plants, and presents the fascinating natural history and diversity of green plants in a taxonomic and evolutionary context. This title also asks and answers the questions: Why are there so many plant species in the world? And how can so many plants grow together in a given patch of prairie, forest, or wetland? Through the study of plant diversity, students will gain an appreciation of the natural world far beyond the classroom and the study of botany, to an understanding of how our actions impact the world around us. Plant Diversity, Second Edition is suitable as a supplementary text for a biology course or as recreational reading for the interested student.

Mit Zeichnungen von Paul Flora
by Wolfgang Hildesheimer, Paul Flora, Wolfgang Hildesheimer
Wolfgang Hildesheimer wurde am 9. Dezember 1916 als Sohn jüdischer Eltern in Hamburg geboren und starb am 21. August 1991 in Poschiavo in der Schweiz. 1933 emigrierte er über England nach Palästina, wo er eine Schreinerlehre absolvierte. 1937 begann er an der Central School of Arts and Crafts (London) Malerei, Textilentwurf und Bühnenbildnerei zu studieren und nahm von London aus am Sommerkurs für Bühnenbild bei Emil Pirchan in Salzburg teil. Anfang 1939 gestaltete er in London am Tavistock Little Theatre sein erstes Bühnenbild. Nach dem Ausbruch des Zweiten Weltkriegs kehrte er nach Palästina zurück, arbeitete als Information Officer, war Englisch-Lehrer am British Institute und leitete zusammen mit einem Freund einige Zeit die Werbeagentur »HW«. Er beteiligte sich an Kunstausstellungen und veröffentlichte einige Gedichte, Essays und Kritiken. 1946 kehrte er nach London zurück, um Bühnenbildner zu werden, wurde aber für die Nürnberger Prozesse engagiert. Im Januar 1947 reiste er nach Nürnberg, dolmetschte für die amerikanische Besatzungsmacht und beteiligte sich wieder an Kunstausstellungen. 1949 zog er nach Ambach am Starnberger See, um als freier Maler und Grafiker zu arbeiten, schrieb im Januar 1950 aber eine Geschichte für Kinder – der Beginn seiner literarischen Karriere. Bereits 1951 wurde er zur Gruppe 47 eingeladen, 1955 erhielt er den Hörspielpreis der Kriegsblinden und im selben Jahr wurde zudem sein erstes Theaterstück von Gustav Gründgens uraufgeführt; ebenfalls in diesem Jahr begann er auch wieder zu malen. Nachdem er 1953 nach München gezogen war, übersiedelte er 1957 nach Poschiavo und widmete sich einer neuen Art von Theaterstücken, deren Besonderheiten er 1960 mit der Rede Über das absurde Theater fundierte. Anlässlich der Internationalen Theaterwoche der Studentenbühnen in Erlangen gehalten, sorgte diese für Aufsehen. Sein Prosabuch Tynset wurde 1966 mit dem Georg-Büchner-Preis und dem Bremer Literaturpreis ausgezeichnet. Sein Bestseller Mozart (1977) beeinflusste das Theaterstück und den Film Amadeus. Seit 1961 beteiligte er sich wieder an Ausstellungen, seit 1965 wurde sein bildkünstlerisches Werk in rund fünfzig Einzelausstellungen gezeigt. 1980 hielt Hildesheimer die Eröffnungsrede der Salzburger Festspiele Was sagt Musik aus. Neben seinen literarischen Werken verfertigte Hildesheimer auch Collagen, die er in mehreren Bänden sammelte. Spektakulär war 1984 seine Ankündigung, angesichts der drohenden Umweltkatastrophe nicht mehr zu schreiben, sondern zur bildenden Kunst zurückzukehren. Wolfgang Hildesheimer wurde am 9.
