Lhwyd, the illegitimate son of a father ruined by the Civil War, had to make his own way in the world. A competent botanist before going up to Oxford as a student, he spent much time there at the Botanical Garden before being appointed to the newly established Ashmolean Museum, where he became its second Keeper. This biography traces the development of his research interests from botany to palaeontology - and then to antiquarian studies, which led to him studying the Celtic languages as a source of linguistic evidence in historical studies. Thus he became the founder of Celtic Studies. Lhwyd's diverse research interests were underpinned by an evidence-led methodology - the collection (by personal observation where possible) of material, which would then be classified as a preliminary to drawing conclusions - and, as such, his is a valuable contribution to the history of science.

This new edition of Fungi in Ecosystem Processes continues the unique approach of examining the roles of fungi from the perspective of ecosystem functions. It explores how fungi have adapted to survive within particular constraints, how they help to maintain homeostasis in ecosystems, how they facilitate resistance to perturbations, and how they influence the communities of other organisms. Updated and revised, the second edition Expands the section on plant pathogens, invasive species, and insect-fungal interactions Provides more extensive coverage on insect-fungal interactions, including entomopathogens, the links between entomopathogens and endophytes, and symbiotic and mutualistic interactions Adds a new section on fungi in the built environment Presents new material on below-ground to above-ground interactions mediated through fungi, such as mycorrhizal signaling systems for herbivory defense The book also includes expanded coverage of the role of fungi in suppressive soils, aquatic and marine fungi, modern methods of following food chains in fungal-invertebrate trophic interactions, and the physiology of nutrient uptake by mycorrhizae. A necessary update and expansion to previous material, this book provides an essential reference on the current understanding of fungal roles in ecosystem processes.

A field guide for the wildflowers of the Texas High Plains. 141 color photographs and descriptions, glossary of terms, and key to the various flower families.

This book discusses theoretical approaches to the taxonomy of biological systems and theory and mathematical approaches to the problem of plant diversity, cultivation, and the environment. Particular attention is given to theoretical and practical problems of soil and the environmental sustainability of phytocoenosis, with the goal to enhance the productivity of agricultural crops: cereals, legumes, vegetables, and fruit. Providing valuable information on the distribution of chemical elements in the soil-plant system and on the migration of chemical elements in the food chain, this book looks at the composition of the soil and the distribution of elements in the soil-plant system that are manifested as adaptations of plant organism to environmental conditions. With chapters written by acknowledged scientists in the field of genetics, plant selection, ecology, and agro-economy, the book attempts, in many cases, to find consensus between the need to address ways to decrease the excess load on the environment and the need to provide adequately for the human population in agro-developed countries. This book also presents precision farming techniques, including the introduction of differentiated agrochemicals and considering variability of soil fertility and crop conditions. An important element for the conservation and adaptation of plant organism to environmental conditions is the use of physiologically active compounds.

Cannabis sativa is best known as the source of marijuana, the world's most widely consumed illicit recreational drug. However, the plant is also extremely useful as a source of stem fiber, edible seed oil, and medicinal compounds, all of which are undergoing extremely promising research, technological applications, and business investment. Indeed, despite its capacity for harm as a recreational drug, cannabis has phenomenal potential for providing new products to benefit society and for generating extensive employment and huge profits. Misguided policies, until recently, have prevented legitimate research on the beneficial properties of cannabis, but there is now an explosion of societal, scientific, and political support to reappraise and remove some of the barriers to usage. Unfortunately, there is also a corresponding dearth of objective analysis. Towards redressing the limitation of information, Cannabis: A Complete Guide is a comprehensive reference summarizing botanical, business, chemical, ecological, genetic, historical, horticultural, legal, and medical considerations that are critical for the wise advancement and management of cannabis in its various forms. This book documents both the risks and benefits of what is indisputably one of the world's most important species. The conflicting claims for medicinal virtues and toxicological vices are examined, based mainly on the most recent authoritative scientific reviews. The attempt is made consistently to reflect majority scientific opinion, although many aspects of cannabis are controversial. Aside from the relevance to specialists, the general public should find the presentation attractive because of the huge interest today in marijuana. Unfortunately, society has become so specialized and compartmentalized that most people have limited appreciation of the importance of science to their lives, except when a topic like marijuana becomes sensationalized. This review of cannabis can serve as a vehicle for public education in the realm of science and technology. Indeed, towards the goal of disseminating the important information in this book to a wide audience, the presentation is user-friendly, concise, and well-illustrated in the hope that non-specialists will find the topics both informative and entertaining.

This book investigates the fundamental role that tropical bioproductivity - or more specifically net primary productivity - has played in shaping the global geographies of food, finance, governance and people. The book examines the basic astronomical and thermal properties of our planet to illustrate the dynamic nature of the tropics and how the region resides at the very heart of global energetics, driving the environmental flows that shape planetary climate and bioproductivity. The author explores how the region's relatively small, but hyper-productive, land area provided the groundswell for the economic, social, political and demographic changes that fuelled empires, European colonialism and nation-building. Also covered are discussions on how the critical intake of capital needed to fuel the industrial and technological revolutions driving modern globalization was first expropriated from the tropics by harnessing the region's natural productivity and biological crop diversity and then transforming it into tradeable commodities using the inhabitants' labour and knowledge. With modern tropical nations accounting for the bulk of people living in poverty and registering some of the highest income disparities, the author presents cross-cutting evidence showing that their histories and the persistence of expropriating institutions have fostered anocratic tendencies, poor governance, unorthodox financial flows and mass migration. Tropical Bioproductivity cuts across vast geographies, topics and histories to deliver a readable narrative that links people, places and events with the environmental mechanics of our planet. It will be of interest to students and researchers in the areas of environmental studies, economics, history, agriculture, anthropology and geography.

An exquisitely illustrated, lively exploration of Latin plant names for gardeners. More than just a dictionary, this fascinating book explains the meanings behind hundreds of Latin plant terms, their flowering times, leaf patterns, natural habitats and all sorts of other useful information. Every gardener needs to know their Latin names. They may look confusing at first, but once you understand what certain key words mean, impenetrable-sounding and hard-to-pronounce species names are suddenly demystified. Many Latin names hide the secrets of where the plant is found, its colour, flowering times, leaf pattern, natural habitat and all sorts of other information that's extremely useful to the gardener: if you want a plant for a shady place, choose one with a name ending in sylvestris ('of woods'), while if your garden is dry, look out for the suffix epigeios ('of dry places'). More than just a dictionary of plant names, this fascinating book explains the meaning of hundreds of Latin plant terms, grouped into handily themed sections such as plants that are named after famous women, plants that are named after the shape of their leaves, plants that are named after their fragrance or the time of year that they flower. Within these pages you'll learn that Digitalis purpurea (the common foxglove) is purple, that the sanguineum in Geranium sanguineum means 'bloody' (its common name is the bloody cranesbill), and to steer clear of any plant whose Latin name ends in infestus.

Harmal: The Genus Peganum is an in-depth treatment of one of the most commanding plants in the botanical kingdom. Humble in appearance, modest in its needs, Peganum harmala has been venerated for millennia as a Deity-manifesting entheogen and a powerful medicine. This book traverses harmal's medicinal chemistry, its possible role in the origins of religion, and its employment from ancient times to the present in the therapy of patients suffering from infections, infestations, metabolic derangements, neurological degeneration, visual weakness, and cancer. Its peculiar indolic compounds, known as harmala alkaloids, are now appreciated as exerting profound effects on the mind and on the body. These effects are the result of the alkaloids' interactions with, and binding to, serotonin receptors on the cell surfaces of neurons in the brain and lymphocytes in the blood, the latter constituting the diffuse structural basis of the immune system. This biphasic modulation by harmala alkaloids has led to a novel pharmacologic re-visioning presented herein for the first time, the concept of a "lymphoneuric syncytium" and its possible long term tuning via "somatodelic" as well as "psychedelic" effects. The scientific rationale underlying the use of harmal in the medicines of the past and the healing technologies of our future is developed through exhaustive and meticulous explorations in both ethnopharmacology and modern phytochemistry. The presentation is enhanced through appraisals of the effects of harmal in two clinical cancer case scenarios, and of intentional inebriation and "provings" by one of the authors and a psychiatric colleague. The noted and esteemed botanically-trained physician Dr. Andrew Weil states in his Preface that this "monumental" volume will become the standard reference work in the field. Harmal: The Genus Peganum will be an invaluable addition to the personal libraries of professional pharmacognosists, botanists, physicians, psychologists, neuroscientists, and all persons interested in the interrelationship of consciousness, medicine, and coevolution.

Sports officials (umpires, referees, judges) play a vital role in every sport, and sports governing bodies, fans, and players now expect officials to maintain higher professional standards than ever before. In this ground-breaking book, a team of leading international sport scientists and top level officials have come together to examine, for the first time, the science and practice of officiating in sport, helping us to better understand the skills, techniques and physical requirements of successful refereeing. The book covers every key component of the official's role, including: Training and career development Fitness and physical preparation Visual processing Judgement and decision-making Communication and game management Psychological demands and skills Using technology Performance evaluation Researching and studying officials in sport Top-level officials or officiating managers contribute in the 'Official's Call' sections, reflecting on their experiences in real in-game situations across a wide range of international sports, and on how a better understanding of science and technique can help improve professional practice. No other book has attempted to combine leading edge contemporary sport science with the realities of match officiating in this way, and therefore this book is vital reading for any advanced student of sport science, sport coaching or sport development, or any practising official or sports administrator looking to raise their professional standards.

Recent advances in science have clarified the role of plant specialized metabolites (classically known as plant secondary metabolites), which cannot be considered only bioactive molecules used for human health but also pivotal factors for the global ecosystem. They play major roles in plant life, evolution, and mutualism. To provide the reader a general view of plant specialized metabolites, it is important to consider both the biochemistry and the functional/ecological role of these important compounds. Around 200,000 specialized metabolites are formed by a wide array of plant metabolic pathways from numerous plant taxa and through learning how other species (including human beings) rely on them. Plant Specialized Metabolism: Genomics, Biochemistry, and Biological Functions will provide the reader with special insights into the sophisticated nature of these metabolites and their various and valuable uses based on the most recent findings in science. The field of plant specialized metabolism has witnessed tremendous growth in the past decade. This growth has had a profound impact on multiple disciplines in life science, including biochemistry, metabolism, enzymology, natural product chemistry, medicinal chemistry, chemical ecology, and evolution. It also has yielded valuable knowledge and technology readily applicable in various industries, such as agriculture, horticulture, energy, renewable chemicals, and pharmaceuticals. The book focuses on the molecular background of secondary metabolite biosynthesis, their functional role, and potential applications.

Chlorophyll a fluorescence is a tool for evaluating plant responses to stress conditions. Fluorescence can be used in plant phenotyping and breeding programs to monitor biotic and abiotic stresses including mineral deficiencies, soil salinity, and pathogenic diseases. Chlorophyll Fluorescence: Understanding Crop Performance - Basics and Applications reviews a diversity of instruments available for recording and analyzing different types of light signals from plants and addresses the use of chlorophyll a fluorescence in research on plants and other photosynthesizing organisms, such as algae and cyanobacteria. This book characterizes the phenomenon of chlorophyll a fluorescence, describes the methods for its measurement, and demonstrates - using selected examples - the applicability of these methods to research the response of the photosynthetic apparatus and plant tolerance to unfavorable environmental conditions. In addition, chapters cover a general background on photosynthesis, analysis of delayed fluorescence, and the pulse amplitude modulated (PAM) technique. The book is addressed to a wide range of professionals in photosynthesis research and scientists from other areas of plant sciences.

This book is one of a series of more than 20 volumes resulting from the World Archaeological Congress, September 1986, attempting to bring together not only archaeologists and anthropologists from many parts of the world, as well as academics from contingent disciplines, but also non-academics from a wide range of cultural backgrounds. This volume develops a new approach to plant exploitation and early agriculture in a worldwide comparative context. It modifies the conceptual dichotomy between "hunter-gatherers" and "farmers," viewing human exploitation of plant resources as a global evolutionary process which incorporated the beginnings of cultivation and crop domestication. The studies throughout the book come from a worldwide range of geographical contexts, from the Andes to China and from Australia to the Upper Mid-West of North America. This work is of interest to anthropologists, archaeologists, botanists and geographers. Originally published 1989.

Cytogenetics plays an important role in understanding the chromosomal and genetic architecture of plant species. Plant Cytogenetics, Third Edition follows the tradition of its predecessors presenting theoretical and practical aspects of plant cytogenetics. Chapters describe correct handling of plant chromosomes, methods in plant cytogenetics, cell division, reproduction methods, chromosome nomenclature, karyotype analysis, chromosomal aberrations, genome analysis, transgenic crops, and cytogenetics in plant breeding. This new edition begins with a brief introduction on the historical aspect of cytogenetics and flows directly into handling of plant chromosomes by classical and modern cytological techniques, classical Mendelian Genetics, brief description of cell division, and chromosome identification by karyotype analysis. The comprehension of cytogenetics is incomplete without information on the role of aneuploidy in associating a gene on a particular chromosome, and the book covers these methodologies as a primary topic. Covering classical to modern cytogenetics, the book presents to the reader the crucial role of cytogenetics in improving crops.
