Available in PDF, EPUB and Kindle. Book excerpt: An invaluable source of up-to-date information on all major aspects of weed persistence Weeds negatively impact crop yields, the quality of agricultural produce, the health of livestock and ecosystems, and various aspects of human life. Despite significant expenditures of time, money, and resources by agricultural producers, land managers, and the general public, weeds persist. Developing new methods for protecting crops and the environment requires a thorough understanding of the persistence mechanisms of weeds. In Persistence Strategies of Weeds, an international team of expert authors provide detailed information on weed seed biology, identify the vulnerabilities of different weeds, and address the underlying issues behind the problem of weed persistence despite various management methods including herbicides. Presenting a comprehensive approach to the subject, the authors describe what is already understood about weed persistence and what yet needs to be determined. Topics include the role of seed production, dissemination, seed banks, the physiology and genetics of seed dormancy, the influence of agronomic practices, seed longevity, vegetative propagation, allelopathy, predation, soil microbes, weed evolution, and more. This authoritative volume: Examines the genetic flexibility of weeds to adapt to changes in agricultural practices and management strategies Discusses the release of allelochemicals by certain weeds that inhibit the growth of competing plant species Explores the influence of climate change on weed persistence and how the efficacy of herbicides will be affected Emphasizes the importance of sustainable crop production and reducing dependence on synthetic herbicides Provides extensive coverage of the roles of genetic, environmental, and morphological factors in the regulation of weed seed dormancy Includes an overview of persistence strategies of weeds, detailed case studies, and numerous illustrative examples Persistence Strategies of Weeds is an ideal textbook for all upper-level undergraduate and graduate students of weed and pest biology, agroecology, or organic agriculture, and a must-have reference for weed scientists and weed management professionals.

Download or read book Wild Persistence written by Patricia Hooper and published by . This book was released on 2019 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The poems in Wild Persistence often involve moments when the human and natural worlds intersect: a Sandhill Crane dancing at the window of a grieving woman, a copperhead snake confronting a gardener, a billboard photo of a missing child slowly being eroded by weather and the passage of time. Although these poems mourn numerous losses, they celebrate the world in which such losses take place, turning for perspective to nature with its cyclical renewals and to the resilience of the human spirit.
Download or read book Spirochetes and Immune Evasion Infection Persistence and Clearance written by Maria Gomes-Solecki and published by Frontiers Media SA. This book was released on 2020-06-04 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interface between spirochetes and the immune response is of significant importance to their pathogenesis and persistence. Evasion from the immune system leads to infections that present as Leptospirosis, Syphilis, Lyme Disease and Relapsing Fever and may lead to putative persistence and latency. Understanding the mechanisms involved in immune evasion will shed light not only on the hostpathogen factors involved in the process but also on how resistance to infection leads to protection. Broad examples include spirochetal interaction with the immune system, spirochetal molecules involved in immune evasion and in immune activation, innate immune responses in the skin and other compartments, factors involved in spirochetal adhesion to the extracellular matrix, interaction of spirochetes with antigen presenting cells, in vitro, ex vivo or in vivo, spirochetal lipoproteins and immunity. Specific examples include innate immunity to pathogenic spirochetes (T. pallidum, B. burgdorferi and Leptospira spp.), invasion and pathogenesis by L. interrogans, subversion and suppression of B cell responses by B. burgdorferi, role of antibody in clearance versus persistence of relapsing fever Borreliae, evasion of the complement system by B. burgdorferi, immune suppression by Ixodes tick saliva for effective transmission, adhesins and enzymes involved in dissemination of T. pallidum, spirochetal variable surface proteins in immune evasion, intravital imaging of pathogenic spirochetes (Borreliae and Leptospira) in host tissues, spirochete-host surface interactions. Additional specific examples for B. burgdorferi include novel approaches to control infection within the vector and/or in mammal; tick innate immune defenses and interaction of Ixodes scapularis salivary immunomodulatory molecules with human immune cells, tick-innate immune defenses (from the perspective of the tick midgut), mouse models of infection and genetic basis for pathogenicity, diverse roles of outer surface protein C. Additional specific examples for Leptospirosis include animal models of acute, sub-lethal and persistent infection; neutrophils and innate immune response; Toll-like receptor mediated B cell responses; markers of endothelial cell activation for disease severity in human leptospirosis, corticosteroid treatment of advanced human leptospirosis, and urinary biomarkers of chronic Leptospirosis.

Download or read book Persistence written by Ivan Coyote and published by arsenal pulp press. This book was released on 2011-05-03 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lambda Literary Award finalist American Library Association Stonewall Honor Book In the summer of 2009, butch writer and storyteller Ivan Coyote and gender researcher and femme dynamo Zena Sharman wrote down a wish-list of their favourite queer authors; they wanted to continue and expand the butch-femme conversation. The result is Persistence: All Ways Butch and Femme. The stories in these pages resist simple definitions. The people in these stories defy reductive stereotypes and inflexible categories. The pages in this book describe the lives of an incredible diversity of people whose hearts also pounded for some reason the first time they read or heard the words "butch" or "femme." Contributors such as Jewelle Gomez (The Gilda Stories), Thea Hillman (Intersex), S. Bear Bergman (Butch is a Noun), Chandra Mayor (All the Pretty Girls), Amber Dawn (Sub Rosa), Anna Camilleri (Brazen Femme), Debra Anderson (Code White), Anne Fleming (Anomaly), Michael V. Smith (Cumberland), and Zoe Whittall (Bottle Rocket Hearts) explore the parameters, history, and power of a multitude of butch and femme realities. It's a raucous, insightful, sexy, and sometimes dangerous look at what the words butch and femme can mean in today’s ever-shifting gender landscape, with one eye on the past and the other on what is to come. Includes a foreword by Joan Nestle, renowned femme author and editor of The Persistent Desire: A Femme-Butch Reader, a landmark anthology originally published in 1992. Ivan E. Coyote is the author of seven books (including the novel Bow Grip, an American Library Association Stonewall Honor Book) and a long-time muser on the trappings of the two-party gender system. Zena Sharman is the assistant director of Canada's national Institute of Gender and Health.
Download or read book Security and Persistence written by John Rosenberg and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: During a short visit to Bremen in December 1989 John Rosenberg had several discussions with me about computer architecture. Although we had previously worked together for more than a decade in Australia we had not seen each other for over a year, following my move to Bremen in 1988. Meanwhile John was spending a year on study leave at the University of St. Andrews in Scotland with Professor Ron Morrison and his persistent programming research group. From our conversations it was quite clear that John was having a most fruitful time in St. Andrews and was gaining valuable new insights into the world of persistent programming. He was very keen to explore the significance of these insights for the MONADS Project, which we had been jOintly directing since the early 1980s. MONADS was not about persistent programming. In fact it had quite different origins, in the areas of software engineering and information protection. In an earlier stage of the project our ideas on these themes had led us into the world of computer architecture and even hardware deSign, in our attempts to provide an efficient base machine for our software ideas. The most important practical result of this phase of the project had been the development of the MONADS-PC, a mini computer which would be better compared with say a V tv

Download or read book Infectious Disease Ecology of Wild Birds written by Jennifer C. Owen and published by Oxford University Press. This book was released on 2021-06-30 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birds are the most diverse group of land vertebrates and have evolved to exploit almost every terrestrial niche on earth. They also serve as a natural reservoir for an array of different pathogens that pose serious health risks to human and domestic animal populations, including West Nile virus, highly pathogenic avian influenza viruses, Newcastle Disease virus, and numerous enteric pathogens. Avian diseases are also critically important to the conservation of endemic bird species in many places around the world. This accessible textbook focuses on the dynamics of infectious diseases for wild avian hosts across every level of ecological hierarchy, from the way pathogens interact with the physiology and behavior of individual hosts, the evolutionary and ecological dynamics of the host-parasite interactions occurring within populations, up to the complex biotic and abiotic interactions occurring within biological communities and ecosystems. Parasite-bird interactions are also increasingly occurring in rapidly changing global environments - thus, their ecology is also changing - and this shapes the complex ways by which parasites influence the inter-connected health of birds, humans, and shared ecosystems. Given the key role of birds in ecological communities more broadly, and as the primary host to so many zoonotic pathogens, an understanding of the ecological and evolutionary principles underlying the maintenance, amplification, transmission, and dispersal of these infectious agents is crucial to understanding how to mitigate the negative global impacts of the ever-increasing number of emerging infectious diseases. Although the topics and principles discussed in this book relate to birds, they have a far wider relevance and can also be applied to non-avian, wildlife host-pathogen systems. The COVID-19 pandemic has shown that understanding of disease ecology in wild animal populations is paramount to global health. Infectious Disease Ecology of Wild Birds is suitable for both senior undergraduate and graduate students taking courses in avian disease ecology, ecoimmunology, ecology, and conservation. It will also appeal to the many professional parasitologists, ecoimmunologists, ornithologists, behavioural ecologists, conservation biologists, and wildlife biologists requiring a concise overview of the topic.

This book was released on 2019-04-05 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coral reef declines have been recorded for all major tropical ocean basins since the 1980s, averaging approximately 30-50% reductions in reef cover globally. These losses are a result of numerous problems, including habitat destruction, pollution, overfishing, disease, and climate change. Greenhouse gas emissions and the associated increases in ocean temperature and carbon dioxide (CO2) concentrations have been implicated in increased reports of coral bleaching, disease outbreaks, and ocean acidification (OA). For the hundreds of millions of people who depend on reefs for food or livelihoods, the thousands of communities that depend on reefs for wave protection, the people whose cultural practices are tied to reef resources, and the many economies that depend on reefs for fisheries or tourism, the health and maintenance of this major global ecosystem is crucial. A growing body of research on coral physiology, ecology, molecular biology, and responses to stress has revealed potential tools to increase coral resilience. Some of this knowledge is poised to provide practical interventions in the short-term, whereas other discoveries are poised to facilitate research that may later open the doors to additional interventions. A Research Review of Interventions to Increase the Persistence and Resilience of Coral Reefs reviews the state of science on genetic, ecological, and environmental interventions meant to enhance the persistence and resilience of coral reefs. The complex nature of corals and their associated microbiome lends itself to a wide range of possible approaches. This first report provides a summary of currently available information on the range of interventions present in the scientific literature and provides a basis for the forthcoming final report.
Download or read book Infectious Diseases from Nature Mechanisms of Viral Emergence and Persistence written by C.J. Peters and published by Springer Science & Business Media. This book was released on 2006-06-07 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant zoonotic diseases have appeared with increasing frequency in recent years. At a symposium held in Galveston, Texas, in March 2004, many outstanding virologists and others presented papers under the broad theme of "emergence". The intent was to elucidate the diseases themselves, the mechanisms by which they have emerged, the publication perception and response to the diseases, and the possibility of prevention or prediction. The papers in this book summarize the talks of this meeting. Among the many timely papers are those by Nobel Prize winner Peter Doherty, influenza epidemiologists Robert Webster and Jeffery Taubenberger, and important contributions by Neal Nathanson, Esteban Domingo, Barry Beaty, David Walker, James Hughes, and others of world expertise.

This book was released on 2017-05-17 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Persistence theory emerged in the early 2000s as a new theory in the area of applied and computational topology. This book provides a broad and modern view of the subject, including its algebraic, topological, and algorithmic aspects. It also elaborates on applications in data analysis. The level of detail of the exposition has been set so as to keep a survey style, while providing sufficient insights into the proofs so the reader can understand the mechanisms at work. The book is organized into three parts. The first part is dedicated to the foundations of persistence and emphasizes its connection to quiver representation theory. The second part focuses on its connection to applications through a few selected topics. The third part provides perspectives for both the theory and its applications. The book can be used as a text for a course on applied topology or data analysis.
