Download or read book Flora of Middle Earth written by Walter S. Judd and published by Oxford University Press. This book was released on 2017-07-18 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few settings in literature are as widely known or celebrated as J.R.R. Tolkien's Middle-Earth. The natural landscape plays a major role in nearly all of Tolkien's major works, and readers have come to view the geography of this fictional universe as integral to understanding and enjoying Tolkien's works. And in laying out this continent, Tolkien paid special attention to its plant life; in total, over 160 plants are explicitly mentioned and described as a part of Middle-Earth. Nearly all of these plants are real species, and many of the fictional plants are based on scientifically grounded botanic principles. In Flora of Middle Earth: Plants of Tolkien's Legendarium, botanist Walter Judd gives a detailed species account of every plant found in Tolkien's universe, complete with the etymology of the plant's name, a discussion of its significance within Tolkien's work, a description of the plant's distribution and ecology, and an original hand-drawn illustration by artist Graham Judd in the style of a woodcut print. Among the over three-thousand vascular plants Tolkien would have seen in the British Isles, the authors show why Tolkien may have selected certain plants for inclusion in his universe over others, in terms of their botanic properties and traditional uses. The clear, comprehensive alphabetical listing of each species, along with the visual identification key of the plant drawings, adds to the reader's understanding and appreciation of the Tolkien canon.

Download or read book Evolutionary Biology written by Mitchell B. Cruzan and published by Oxford University Press. This book was released on 2018-09-11 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the characteristics that distinguish plants from other living organisms can be traced to their bacterial origin early in the history of life. These features-such as a multicellular haploid life stage, prevalent hermaphroditism, self-fertilization, and general dependence on biotic and abiotic vectors for reproduction-stem directly from the plant's ability to obtain energy from the sun. This novel mode of energy capture had far-ranging implications for plant evolution. It not only fueled the tremendous diversification of life on Earth that followed, but also had far-ranging implications for the evolution of photosynthetic microorganisms and eventually for land plants. Understanding the evolutionary processes for the proliferation and diversification of plants requires an appreciation of their unique biological features. While the processes of mutation, selection, genetic drift, and gene flow remain the same for both plants and animals, there are specific characteristics of plants that modify the way their evolution is implemented. Unique traits of plants affect everything from the fate of mutations, through exposure to selection in a haploid life phase, to the distribution of genetic variation within populations, and ultimately the rates and patterns of diversification. This book examines the origins of the unique evolutionary features of plants, as well as their implications for evolutionary processes. Author Mitchell B. Cruzan provides contemporary discussion of subjects including population genetics, phylogeography, phylogenetics, ecological genetics, and genomics. The book fills a need for modern coverage of these topics, all of which are essential to a wide range of advanced courses in plant biology.
Download or read book Essentials of Developmental Plant Anatomy written by Taylor A. Steeves and published by Oxford University Press. This book was released on 2017 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main aim of this book is to provide a developmental perspective to plant anatomy. Authors Steeves and Sawhney provide fundamental information on plant structure and development to students at the introductory level, and as a resource material to researchers working in nearly all areas of plant biology i.e., plant physiology, systematics, ecology, developmental genetics and molecular biology. The book is focused on angiosperm species with some examples from different groups of plants. "Essentials of Developmental Plant Anatomy" starts with an introductory chapter and a brief introduction to plant cell structure, which is followed by the structure of the flower, plant reproduction (vegetative and sexual) and the development and structure of embryo - the precursor to the plant body. Each chapter then deals with essential information on the shoot system, diversity of plant cells and tissues, the structure and development of the stem, leaf, root, and the secondary body.
Download or read book Silvicultural Systems written by John D. Matthews and published by Oxford University Press. This book was released on 1991-08-29 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the theoretical basis and practical application of 20 diverse silvicultural systems for the benefit of ecologists, land-use managers and other professionals. These systems offer the key to regenerating, tending, and harvesting forests in an era of rapid deforestation and increasing demand for wood as fuel and building material. The approaches described here are being used successfully in widely different parts of the world, from Europe to the tropical rain forests, where reduced forest areas must be carefully managed in order to produce the highest possible sustained yield of timber products compatible with environmental protection and preservation. The systematic presentation and discussion of advantages and disadvantages of each program enables readers to select and apply the program most suitable for their needs.
Download or read book Footprints in the Jungle written by Ian A. Bowles and published by Oxford University Press. This book was released on 2001-02-22 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical forests have seen a tremendous growth in logging, mining, and oil and gas development over the past decades. These industries and their infrastructure, including roads and power lines, have a tremendous impact on the environment and often conflict with the growing concern for conservation, particularly the conservation of tropical biodiversity. However, development in the tropics is extremely important economically, both for developing and industrialized nations, and Footprints in the Jungle is an invaluable reference in this important and highly politicized debate. This volume looks at new approaches that lessen the impact of development. It collects numerous case studies by project managers, advocates, and researchers from major international companies, development agencies, universities, and non-governmental organizations. It also examines the environmental and social impact of resource development, proposes a rigorous "best practices" approach, and analyzes a number of challenging technical, environmental, social, and legal issues.

Download or read book Leaf Defence written by Edward E. Farmer and published by OUP Oxford. This book was released on 2014-05-01 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leaves are among the most abundant organs on earth and are a defining feature of most terrestrial ecosystems. However, a leaf is also a potential meal for a hungry animal and the question therefore arises, why does so much foliage survive in nature? What mechanisms protect leaves so that, on a global scale, only a relatively small proportion of living leaf material is consumed? Leaf survival is in large part due to two processes: firstly, leaf-eating organisms fall prey to predators (top-down pressure on the herbivore); secondly, leaves defend themselves (bottom-up pressure on the herbivore). Remarkably, these two types of event are often linked; they are controlled and coordinated by plants and the molecular mechanisms that underlie this are now beginning to emerge. This novel text focuses exclusively on the leaf, on the herbivorous organisms that attack leaves, and the mechanisms that plants use to defend these vital organs. It begins with an assessment of the scale of herbivory, before examining direct physical and chemical defences on leaf surfaces and within the leaf itself. Although some leaf defences are easily seen, most operate at the molecular level and are therefore invisible to the naked eye. Many of these recently elucidated mechanisms are described. Throughout the book, perspectives from both the laboratory and the field are combined. A central feature of the work is its emphasis on the coevolution of leaf defences and the digestive tracts of animals including humans, making the book of relevance in understanding the role of leaf defences in agriculture. Leaf Defence is suitable for senior undergraduate and graduate students taking courses in plant science, as well as a broader audience of biologists and biochemists seeking a comprehensive and authoritative overview of this exciting and emerging topic.

Download or read book Plant Behaviour and Intelligence written by A. J. Trewavas and published by . This book was released on 2014 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a convincing argument for the view that whole cells and whole plants growing in competitive wild conditions show aspects of plant behaviour that can be accurately described as 'intelligent'. Trewavas argues that behaviour, like intelligence, must be assessed within the constraints of the anatomical and physiological framework of the organism in question. The fact that plants do not have centralized nervous systems for example, does not exclude intelligent behaviour. Outside the human dimension, culture is thought largely absent and fitness is the biological property of value. Thus, solving environmental problems that threaten to reduce fitness is another way of viewing intelligent behaviour and has a similar meaning to adaptively variable behaviour. The capacity to solve these problems might be considered to vary in different organisms, but variation does not mean absence. By extending these ideas into a book that allows a critical and amplified discussion, the author hopes to raise an awareness of the concept of purposive behaviour in plants.

Download or read book The Emerald Planet written by David Beerling and published by Oxford University Press. This book was released on 2017-05-12 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants have profoundly moulded the Earth's climate and the evolutionary trajectory of life. Far from being 'silent witnesses to the passage of time', plants are dynamic components of our world, shaping the environment throughout history as much as that environment has shaped them. In The Emerald Planet, David Beerling puts plants centre stage, revealing the crucial role they have played in driving global changes in the environment, in recording hidden facets of Earth's history, and in helping us to predict its future. His account draws together evidence from fossil plants, from experiments with their living counterparts, and from computer models of the 'Earth System', to illuminate the history of our planet and its biodiversity. This new approach reveals how plummeting carbon dioxide levels removed a barrier to the evolution of the leaf; how plants played a starring role in pushing oxygen levels upwards, allowing spectacular giant insects to thrive in the Carboniferous; and it strengthens fascinating and contentious fossil evidence for an ancient hole in the ozone layer. Along the way, Beerling introduces a lively cast of pioneering scientists from Victorian times onwards whose discoveries provided the crucial background to these and the other puzzles. This understanding of our planet's past sheds a sobering light on our own climate-changing activities, and offers clues to what our climatic and ecological futures might look like. There could be no more important time to take a close look at plants, and to understand the history of the world through the stories they tell. Oxford Landmark Science books are 'must-read' classics of modern science writing which have crystallized big ideas, and shaped the way we think.
