This manual brings together information on all phases of seed handling and presents the results of more than 20 years of studies. Forest Service field personnel at several experiment stations and regional offices furnished a backlog of source material for treatments of individual genera. The manual consists of two main parts. Part 1 formulates general principles on the various phases of seed handling from formation of the seed to sowing. Part 2, which forms the larger part of the manual, provides relatively detailed but concise information for 444 species and varieties of trees and shrubs; this includes data on distribution and use, discussions of seeding habits, methods of seed collection, extraction and storage, seed germination, and nursery and field practice.
This edited volume examines the relationship between collective intentionality and inferential theories of meaning. The book consists of three main sections. The first part contains essays demonstrating how researchers working on inferentialism and collective intentionality can learn from one another. The essays in the second part examine the dimensions along which philosophical and empirical research on human reasoning and collective intentionality can benefit from more cross-pollination. The final part consists of essays that offer a closer examination of themes from inferentialism and collective intentionality that arise in the work of Wilfrid Sellars. Groups, Norms and Practices provides a template for continuing an interdisciplinary program in philosophy and the sciences that aims to deepen our understanding of human rationality, language use, and sociality.
Brucella is a genus of Gram-negative, facultative, intracellular bacteria that are highly pathogenic for a variety of mammals, including humans. Recently the WHO cited brucellosis to be the world's most widespread zoonosis. An important feature of the pathogenicity of these organisms is their ability to survive and replicate within the host macrophages. However the mechanism for this is unclear. In addition, none of the classical bacterial virulence factors found in other bacterial pathogens have been found in the genomes of the forty Brucella species and biovars analysed to date. Nevertheless the application of systems biology approaches in recent years has transformed research, permitting fascinating new insights into Brucella molecular biology and genomics. Written by highly acclaimed Brucella scientists, this book comprehensively reviews the most important advances in the field. Opening chapters focus on genetic diversity within Brucella, covering both classical and new species. Pa
This book provides a guided approach to the geostatistical modelling of compositional spatial data. These data are data in proportions, percentages or concentrations distributed in space which exhibit spatial correlation. The book can be divided into four blocks. The first block sets the framework and provides some background on compositional data analysis. Block two introduces compositional exploratory tools for both non-spatial and spatial aspects. Block three covers all necessary facets of multivariate spatial prediction for compositional data: variogram modelling, cokriging and validation. Finally, block four details strategies for simulation of compositional data, including transformations to multivariate normality, Gaussian cosimulation, multipoint simulation of compositional data, and common postprocessing techniques, valid for both Gaussian and multipoint methods. All methods are illustrated via applications to two types of data sets: one a large-scale geochemical survey, comprised of a full suite of geochemical variables, and the other from a mining context, where only the elements of greatest importance are considered. R codes are included for all aspects of the methodology, encapsulated in the R package "gmGeostats", available in CRAN.

It is important for students, researchers, and wildlife professionals to understand the growing set of population genomics tools that can address issues from delineation of wildlife populations to assessing their capacity to adapt to environmental change. This book brings together leading experts in wildlife population genomics to discuss the key areas of the field, as well as challenges, opportunities and future prospects of wildlife population genomics.
The book will benefit a reader with a background in physical sciences and applied mathematics interested in the mathematical models of genetic evolution. In the first chapter, we analyze several thought experiments based on a basic model of stochastic evolution of a single genomic site in the presence of the factors of random mutation, directional natural selection, and random genetic drift. In the second chapter, we present a more advanced theory for a large number of linked loci. In the third chapter, we include the effect of genetic recombination into account and find out the advantage of sexual reproduction for adaptation. These models are useful for the evolution of a broad range of asexual and sexual populations, including virus evolution in a host and a host population.
In the statistical domain, certain topics have received considerable attention during the last decade or so, necessitated by the growth and evolution of data and theoretical challenges. This growth has invariably been accompanied by computational advancement, which has presented end users as well as researchers with the necessary opportunities to handle data and implement modelling solutions for statistical purposes. Showcasing the interplay among a variety of disciplines, this book offers pioneering theoretical and applied solutions to practice-oriented problems. As a carefully curated collection of prominent international thought leaders, it fosters collaboration between statisticians and biostatisticians and provides an array of thought processes and tools to its readers. The book thereby creates an understanding and appreciation of recent developments as well as an implementation of these contributions within the broader framework of both academia and industry. Computational and Methodological Statistics and Biostatistics is composed of three main themes: * Recent developments in theory and applications of statistical distributions;* Recent developments in supervised and unsupervised modelling;* Recent developments in biostatistics; and also features programming code and accompanying algorithms to enable readers to replicate and implement methodologies. Therefore, this monograph provides a concise point of reference for a variety of current trends and topics within the statistical domain. With interdisciplinary appeal, it will be useful to researchers, graduate students, and practitioners in statistics, biostatistics, clinical methodology, geology, data science, and actuarial science, amongst others.
The second edition of this book brings together a cutting edge international team of contributors to critically review the current knowledge regarding the effectiveness of training interventions designed to improve cognitive functions in different target populations. Since the publication of the first volume, the field of cognitive research has rapidly evolved. There is substantial evidence that cognitive and physical training can improve cognitive performance, but these benefits seem to vary as a function of the type and the intensity of interventions and the way training-induced gains are measured and analyzed. This book will address the new topics in psychological research and aims to resolve some of the currently debated issues. This book offers a comprehensive overview of empirical findings and methodological approaches of cognitive training research in different cognitive domains (memory, executive functions, etc.), types of training (working memory training, video game training, physical training, etc.), age groups (from children to young and older adults), target populations (children with developmental disorders, aging workers, MCI patients etc.), settings (laboratory-based studies, applied studies in clinical and educational settings), and methodological approaches (behavioral studies, neuroscientific studies). Chapters feature theoretical models that describe the mechanisms underlying training-induced cognitive and neural changes. Cognitive Training: An Overview of Features and Applications, Second Edition will be of interest to researchers, practitioners, students, and professors in the fields of psychology and neuroscience.
This book provides a comprehensive overview of the current state of knowledge on plant-microbiome interactions and associations. It covers all major mechanistic approaches used to investigate microbes' impacts on plant growth promotion, disease control and health. The industrial manufacture of nitrogen currently accounts for roughly 2% of the world's total energy consumption. Microbial products are expected to reduce the need for costly fertilizers, as well as chemical pesticides and fungicides. While beneficial microorganisms are increasingly being used in agriculture, abiotic and biotic stresses such as heat, drought, cold, and salt can quickly kill or render them useless in the field. However, discovering new and better treatments is a lengthy process due to the considerable microbial diversity found in soils. Researchers have now proposed using biotechnological approaches to accelerate the process of microbial technology development. The fact that plant-associated microbes stimulate plant growth and development is well known, as the examples of rhizobia and mycorrhizal fungi show. The mechanisms by which these microorganisms maintain plant growth include the production of phytohormones, fixation of nitrogen, and the mobilization of phosphorus and minerals. The plant microbiome is also involved in pathogen suppression, and especially the root microbiome acts as a protective shield against soil-borne pathogens. A special feature of this book is its multidisciplinary approach, spanning from plant microbiology/biocontrol, fungal and bacterial endophytes, plant physiology, to biochemistry, proteomics and genomics. It is ideally suited for researchers and student of agri-biotechnology, soil biology and fungal biology.
This book provides a comprehensive overview of recent research on estuaries of the east coast of India, and how changing biogeochemical dynamics as a result of climate change and human activity have impacted estuaries and other open water ecosystems. Though estuaries only cover a very small portion of the earth's hydrosphere, they are some of the most biogeochemically active regions among the global water bodies. As such, this book focuses on estuaries of the east coast of India going all the way to the Bay of Bengal, which is the world's largest freshwater input from perennial rivers and rain-fed estuaries, and is therefore a unique area of study. Through its unique coverage of the Bay of Bengal in particular, the book presents a new perspective not present in the literature on estuary biogeochemistry and ecosystem dynamics. Moreover, the book addresses SDG 13 (Climate Action) and 14 (Life below Water), with a focus on ecosystem services of the natural aquatic system.The book will be useful to researchers, policy makers, coastal managers and marine sustainability scientists and organizations.

This book reprints Human Guinea Pigs, by Kenneth Mellanby, a seminal work in the history of medical ethics and human subject research that has been nearly unavailable for over 40 years. Detailing the use of World War II conscientious objectors who volunteered for experimentation on scabies transmission, Mellanby's book offers insight into one approach to human subject experimentation before the development of ethical oversight regulations. His work was initially published prior to the articulation of the Nuremberg Code, which makes his subsequent position as a reporter for the British Medical Journal at the Nuremberg Trials very interesting, particularly given his sometimes controversial opinions on Nazi medical experimentation. This book reprints the second edition together with commentary essays that situate Mellanby's ethical approach in historical context and relative to contemporary approaches. This volume is of particular interest to scholars of the history of human subject research.
This book summarizes various tools and techniques used to provide insights into the cellular and molecular pathophysiology of stroke. It also presents rodent animal models to help shed light on the pathophysiology of ischemic stroke. Presenting the latest information on the different types of stroke, including embolic, filament, photothrombotic, and bilateral common carotid artery, the book also describes techniques that are used for confirmation of stroke surgery, such as laser speckle imaging (LSI) and laser Doppler flowmetry (LDF), and discusses the non-human primates that are used in stroke surgery, cerebral venous sinuous thrombosis, and neurobehavioral assessment. Lastly, it analyzes various neuroprotective agents to treat and prevent ischemic stroke, and examines the challenges and advances in treating and preventing acute ischemic stroke.

In studying biology, one of the more difficult factors to predict is how parents' attributes will affect their children and how those children will affect their own children. Organizing and calculating those vast statistics can become extremely tedious without the proper mathematical and reproductive knowledge. Attractors and Higher Dimensions in Population and Molecular Biology: Emerging Research and Opportunities is a collection of innovative research on the methods and applications of population logistics. While highlighting topics including gene analysis, crossbreeding, and reproduction, this book is ideally designed for academics, researchers, biologists, and mathematicians seeking current research on modeling the reproduction process of a biological population.
This book provides a conceptually organized framework to understand the phenomenon of biological invasions at the Anthropocene global scale. Most advances toward that aim have been provided from North American and European researchers, with fewer contributions from Australia and South Africa. Here we fill the void from the Neotropics, focusing on the research experience in South American countries, with a strong emphasis on Argentina and Chile. The text is divided into two parts: The first half comprises self-contained chapters, providing a conceptual, bibliographic and empirical foundation in the field of invasion biology, from an Anthropocene perspective. The second half reviews the ecology, biogeography, and local impacts in South America of exotic species groups (European rabbit, Eurasian wild boar, Canadian beaver, North American mink, and Holarctic freshwater fishes), which are shown to be useful models for case studies of global relevance.
This volume discusses how environmental pollutants are involved in the pathogenesis of neurological disorders, and covers specific mechanisms and risk factors, as well as the necessary strategies to reduce the adverse impacts of environmental pollutants on the human nervous system. With a collection of contributions from experts in environmental pollution, neurology and pharmaceutical chemistry, the book provides both an introduction to the pathogenesis of neurodegeneration, including the types and different classes of neurological disorders, and studies demonstrating the clear link between environmental contaminants (e.g. pesticides, smoking, mycotoxins, persistent organic pollutants (POP's), polychlorinated biphenyls, phthalates, nanomaterials) and the development of neurological disorders in vulnerable populations. The book fills in a gap in research on the topic by also covering state-of-the-art treatment strategies and mitigation measures for each type of pollutant. The book will be of interest to environmental scientists, pharmacologists, toxicologists, biochemists, biotechnologists, and food and drug regulatory organizations. |
