        Parasites and Biological Invasions

        by Jamie Bojko, Alison M Dunn, April M H Blakeslee

        Biological invasions - the introduction, establishment and spread of invasive alien species - are complex global phenomena that can cause significant environmental, ecological, and economic harm. Along with the direct effects of an invasive host organism, there is the additional threat of co-introduced pathogenic and parasitic species. Co-introduced parasites can affect the success of the invasive organism but can also go on to infect hosts in the new range, resulting in novel ecological interactions and complex impacts. These 'Invasive Parasites' can have profound impacts on the success of a biological invasion, and can pose a significant risk to wildlife, in addition to organisms cultured for agriculture and aquaculture. Compiling information on parasite invasions for the first time, this unique book: - provides an in-depth resource on parasite invasions, revealing the subtleties underlying biological invasions and co-introduced disease; - examines the phenomenon and consequences of parasite release in invaded host communities; - explores parasite invasion impacts, interactions and diagnostic techniques; - includes case studies across a broad range of hosts (plants, vertebrates and invertebrates) and parasites (viruses to large Metazoa), from a plethora of aquatic and terrestrial environments. Authored by leading researchers in the discipline, this new book is a useful tool for helping invasion researchers incorporate disease data into their invasion models, as well a vital resource for researchers, policy makers, and environmental managers that are more generally interested in the myriad consequences of species invasions

        RNAi for Plant Improvement and Protection

        by Bruno Mezzetti, Jeremy Sweet, Lorenzo Burgos

        RNA interference (RNAi) has the potential to make major contributions towards sustainable crop production and protection with minimal environmental impacts compared to other technologies. RNAi is being developed and exploited both within plants (i.e. host-induced gene silencing, HIGS) and/or as topical applications (e.g. spray-induced gene silencing, SIGS) for targeting pest and pathogen genes and for manipulating endogenous gene expression in plants. Chapters by international experts review current knowledge on RNAi, methods for developing RNAi systems in GM plants and applications for crop improvement, crop production and crop protection. Chapters examine both endogenous systems in GM plants and exogenous systems where interfering RNAs are applied to target plants, pests and pathogens. The biosafety of these different systems is examined and methods for risk assessment for food, feed and environmental safety are discussed. Finally, aspects of the regulation of technologies exploiting RNAi and the socio-economic impacts of RNAi technologies are discussed.

        Lexicon of Medicinal Plants

        by Prof. Dr. Dietrich Frohne (†), in collaboration with Prof. Dr. Birgit Classen

        Indian mulberry, St. John’s wort, Hawaiian baby woodrose – whether disputed wonder drug, traditional medicinal plant or unknown exotic plant – the Lexicon of Medicinal Plants can always be relied upon. The lexical and classic knowledge about the individual medicinal plants – such as family, origin, use, effect and constituents – garnered over decades and peppered with particular anecdotes on the herbal drugs, can be regarded as unique and largely timeless. At the repeated request of readers, this reference work has therefore been reissued in book form, with its contents largely unchanged but with misprints corrected and its layout modernised. A wealth of experience that even in the fast-moving digital world preserves traditional knowledge.

        Plant 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.

        Parasitic Plants in African Agriculture

        by Lytton John Musselman, Jonne Rodenburg

        Parasitic Plants in African Agriculture brings together for the first time in a single volume, the ecology, biology, damage, and control of all groups of African parasitic plants including both the relatively few parasites introduced to the continent as well as those native parasites that have spread from within Africa. The book covers the well-known witchweeds and broomrapes but also groups and species that have received less attention including mistletoes, dodders, rice vampire weed, and other species posing threats. The book distinguishes between stem and root parasitic weeds and between holoparasites and (facultative or obligate) hemiparasites. Based on their research and experience collectively spanning six decades, the authors provide an authoritative and state-of-the-art overview of the distribution, biology and impact of these highly specialized weeds and include recommendations for their management. Since parasitic plants in African agriculture primarily affect smallholder farmers, these weeds are explicitly discussed within a context of resource limitations and global changes. Readers are informed on all parasitic plant species relevant to African agriculture and the impact these plants have on crop production and livelihoods of smallholders in a changing world. Current and future management strategies are outlined in terms of their principles and effectiveness as well as their feasibility and affordability for farmers, all of which determine farmer adoption. The final chapter synthesises some of the relevant findings and statistics regarding parasitic weed distribution and their host crops and discusses implications in terms of future crop protection concerns in African agricultural systems. Key features: · Authoritative text based on extensive field and laboratory work. · First comprehensive state-of-the-art overview of parasitic plants and their management in Africa. · Highly illustrated with photos, graphs and species distribution maps. · Reviews previous basic and applied work, with relevance to smallholder farming systems. This book will be a valuable reference for students, researchers, extension workers, development officers, national agriculture researchers, plant pathologists, food security specialists, weed scientists, agronomists and botanists.

        Medicinal Plants used in Traditional Persian Medicine

        by Hartwig Schulz, Seyed Ahmad Emami, Farsad Nadjafi

        Medicinal plants and the natural products within them, still remain the starting point for breakthroughs in the development of safe, pharmacologically active synthetic molecules for use in a wide variety of clinical situations. Traditional Persian Medicine (TPM) is one of the most ancient medical doctrines, and is well-documented in terms of information about diseases, diagnoses and treatments, especially by the application of medicinal plants. TPM has been used for centuries worldwide, and many of these methods are still used in Iran today. This book introduces the basics of TPM, and describes the key medicinal plants which are used for the treatment of different diseases. It also creates possible new targets for research activities in drug discovery of natural products. The book is richly illustrated with coloured figures of historic drawings from old Persian pharmacopoeia and photos of plants in their natural habitats. References to Ayurvedic, Traditional Chinese Medicine and to monastic medicine in Europe are also made. Knowledge about medicinal plants used in TPM still exists in Iran, however, there is a risk that the detailed expertise provided by the older generation will be lost in the near future. It is therefore important that this cultural heritage of humanity is properly preserved. This book provides a valuable, evidence-based resource on TPM for researchers, practitioners and students in medicinal plants, ethnobotany and herbal medicine.

        Plant 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.

        a Central Dogma Perspective and Strategies for Enhancement

        by Showkat Ahmad Ganie, Shabir Hussain Wani

        Gene expression in cells follows a prescribed pathway that conforms to the Central Dogma; where the genetic information stored in DNA is transcribed into RNA and then expressed into proteins, which influences most plant traits. Plant salt tolerance research is directed towards identifying nucleotide variants that could contribute to tolerant phenotypes. This book comprehensively presents the current state of knowledge on plant salt tolerance through meticulous analysis of the processes operating across the Central Dogma. It provides a detailed account of modulation of gene expression through genome editing systems to achieve crop improvement against salt stress. It also provides state-of-the-art information on advances in breeding technologies of genome selection and accelerated de novo domestication for rapidly improving the salt tolerance of plants for global food security. This book: 1.Provides a comprehensive coverage of plant salt tolerance mechanisms. 2.Spotlights various factors functioning along the Central Dogma pathway and their regulation in response to salinity. 3.Examines how these factors function to protect the plants from high salinity. 4.Highlights advances in cutting-edge breeding technologies for improving salt tolerance. The book will be of particular value to students and researchers of plant genetics, molecular biology and physiology and those with an interest in salinity and salt tolerance.

        History and Future of Plants, Planet and People

        Towards a New Ecologically Sustainable Age in People’s Relationships With Plants

        by Alan Hamilton, Pei Shengji

        This fascinating book presents the experiences and pooled knowledge of two very different conservation scientists; Pei Shengji from Sichuan, China and Alan Hamilton from London, UK. They have been drawn together over many years through working on some of the same conservation projects and have discovered that they overlap in their ideas about the sorts of work that needs to be done and how it can best be carried out. The book describes some of their own experiences, set within the contexts of their varied careers and the development of their thinking. Plant conservation is crucial to the preservation of natural ecosystems, but conventional approaches have met with only limited success. The authors have concluded that plant conservationists need social allies - elements of society that have other primary concerns, but whose efforts, if successful, will bring benefits to plant conservation too. It is the state and condition of plants on the ground that ultimately matter in conserving ecosystems, and therefore it is the role of local people who interact directly with them which enables success. Ethnobotany is a key skill required of practical plant conservationists. Its techniques enable them to explore connections between people and plants, learn about local perspectives and establish relationships with the people upon whom conservation and sustainable development relies. This book: recommends how to advance plant conservation, based on real experiences. will inspire more people to become involved in plant conservation. demonstrates how the very different backgrounds of the authors have influenced the courses of their careers, but have enabled them to come to very similar conclusions about conservation practice. demonstrates the importance of geographically-based biocultural diversity, as a counterbalancing force to globalisation.

        Biodiversity and Conservation Along an East African Railway

        A Survey of the Dar es Salaam-Makutupora Standard Gauge Railway, Tanzania

        by Catherine Aloyce Masao, Joel Nobert, Flora John Magige, Edmond Alavaisha, S. Zainabu Bungwa, Philbert Anitha Byabato, Deusdedith Fidelis, Elikana John, Jasson John, Julius Mohamed Kibaja, Heriel Moshy, Athumani Fatina Mturi, R. Juma Mwangi, Henry Ndangalasi, Wilrik Ngalasoni, Alberto Bruno Nyundo, Chacha Werema, Felix A. Shayo, N A Mbwambo

        It is well known that infrastructure development projects can boost the economy and reduce the cost of trade in both developing and developed economies, however, infrastructure projects can also cause biodiversity loss. This book is the result of an important biodiversity survey conducted along an East African railway in Tanzania. The building of the railway, still under construction, has already led to habitat loss, habitat degradation and landscape change which may have affected biodiversity. The book includes recommendations to mitigate the effect of railway construction by protecting biodiversity and ecosystem services which could have major implications across Africa and other regions. The area covered by the survey focuses on the Standard Gauge Railway (SGR) running through the Pugu and Ruvu South Forest Reserves towards Maktupora-Dodoma, plus data on large mammals through to Isaka-Shinyanga. The Pugu forests boast high biodiversity of both flora and fauna, some of which are endemic to the area. There are both plant and animal species that are of major conservation concern so there is urgent need to consolidate information to help formulate suitable conservation measures. The data collected covers plants, invertebrates, amphibians, birds, and mammals for terrestrial and aquatic environments along the SGR. This work is timely as there are many more ongoing SGR construction projects in Tanzania and across Africa, as such construction activities inevitably involve some habitat modification and destruction that may have a negative impact on biodiversity. National and international scientists, decision and policy makers, as well as ecologists and conservation managers involved in large infrastructure projects will find this book invaluable. The book provides baseline information and can be used as a case study for other infrastructure development projects around the world.
