Plants on Plants – The Biology of Vascular Epiphytes

by Gerhard Zotz

This book critically reviews advances in our understanding of the biology of vascular epiphytes since Andreas Schimper's 1888 seminal work. It addresses all aspects of their biology, from anatomy and physiology to ecology and evolution, in the context of general biological principles. By comparing epiphytes with non-epiphytes throughout, it offers a valuable resource for researchers in plant sciences and related disciplines. A particular strength is the identification of research areas that have not received the attention they deserve, with conservation being a case in point. Scientists have tended to study pristine systems, but global developments call for information on epiphytes in human-disturbed systems and the response of epiphytes to global climate change.

Plants on the Move

by Émilie Vast

A gorgeous, lyrical exploration of how seeds travel from plant to plant, take root, and grow. When you think of a plant, you don't think of how it moves. But the feathery seeds of the dandelion fly to other gardens, strawberry tendrils creep, and maple seeds spin. There are many different ways plants move, not only as they grow, but in their quest to reproduce: falling, clinging, floating, burrowing--even exploding!Fourteen plant journeys are chronicled, but more than sixty species are highlighed in Émilie Vast's fantastic and unique art style. Learn the scientific names for the different ways plants move.

Plants, Biotechnology and Agriculture

by Denis Murphy

At a time when the world's food supplies are increasingly unable to meet the needs of a burgeoning population, the subject matter of this book has never been more relevant. At the same time, there is significant diversity of opinion concerning the benefits and perceived dangers of the applications of biotechnology in food production. To help inform this debate, the aim of Plants, Biotechnology & Agriculture is to provide the reader with a comprehensive yet concise overview of plants as both biological organisms and useful resources for people to exploit. The first half of the book gives a basic overview of plant biology including how plants develop and respond to their environment, acting as a primer for those without a biology background and a refresher for students of plant biology and agriculture. These chapters set the scene for an outline of human exploitation of plants, from domestication to scientific manipulation. The complex technologies now being applied to improving crops are then described, guiding the reader through the extensive terminologies and jargon, using focus boxes to illustrate key processes and issues. The final two chapters address society's response to biotechnology, how these technologies are being modified in response to public concerns, and new technologies being developed to meet the challenges of rapid population growth, depletion of non-renewable resources and climate change.

Plants, People, and Culture: The Science of Ethnobotany

by Paul Alan Cox Michael J Balick

Is it possible that plants have shaped the very trajectory of human cultures? Using riveting stories of fieldwork in remote villages, two of the world’s leading ethnobotanists argue that our past and our future are deeply intertwined with plants. Creating massive sea craft from plants, indigenous shipwrights spurred the navigation of the world’s oceans. Today, indigenous agricultural innovations continue to feed, clothe, and heal the world’s population. One out of four prescription drugs, for example, were discovered from plants used by traditional healers. Objects as common as baskets for winnowing or wooden boxes to store feathers were ornamented with traditional designs demonstrating the human ability to understand our environment and to perceive the cosmos. Throughout the world, the human body has been used as the ultimate canvas for plant-based adornment as well as indelible design using tattoo inks. Plants also garnered religious significance, both as offerings to the gods and as a doorway into the other world. Indigenous claims that plants themselves are sacred is leading to a startling reformulation of conservation. The authors argue that conservation goals can best be achieved by learning from, rather than opposing, indigenous peoples and their beliefs. KEY FEATURES • An engrossing narrative that invites the reader to personally engage with the relationship between plants, people, and culture • Full-color illustrations throughout—including many original photographs captured by the authors during fieldwork • New to this edition—"Plants That Harm," a chapter that examines the dangers of poisonous plants and the promise that their study holds for novel treatments for some of our most serious diseases, including Alzheimer’s and substance addiction • Additional readings at the end of each chapter to encourage further exploration • Boxed features on selected topics that offer further insight • Provocative questions to facilitate group discussion Designed for the college classroom as well as for lay readers, this update of Plants, People, and Culture entices the reader with firsthand stories of fieldwork, spectacular illustrations, and a deep respect for both indigenous peoples and the earth’s natural heritage.

Plants, Pollutants and Remediation

by Khalid Rehman Hakeem Münir Öztürk Muhammad Ashraf Ahmet Aksoy M. S. A. Ahmad

In the era of current industrial and civil development, everyone is expressing a deep concern about the problem of environmental pollution. The majority of the global community has a vested interest in supporting and sustaining any move for the protection of environment. In the greater part of the last century it was the fast pace of industrialization, galloping demand for energy and reckless exploitation of natural resources that were mainly responsible for creating the problem of environmental pollution. In the current scenario, high illiteracy rates of the developing nations leads to increasing environmental pollution. When it comes to the hazards of environmental pollution, there is only a very thin dividing line between different countries. One pollutes and the other suffers-there are no eventual winners without significant changes globally. Pollution is posing serious threats to all kinds of diversities on earth in particular plants. The plant world is of vital importance for our planet. It is a worldwide priority aimed at better meeting the needs for food, livelihoods and nature. To meet the food demand of fast-growing population, global food production will have to be doubled. The sustainability of food production depends on the sustainability of plant resources and using tolerant varieties to augment food production. This volume therefore covers discussions on the recent developments in this connection and the emerging role of plants as indicators, remediation, and such related issues as biodiversity conservation and the effects of on edible plants. It reviews issues concerning the future of plant life. Taking cognizance of this, several experts from different parts of the globe have contributed from their experience and knowledge to the critical issues of "Environmental Pollution," and the "Role of Plants in this connection".

Plasma Astrophysics

by Toshi Tajima

The twentieth century has witnessed the transformation of astronomy from celestial mechanics to astrophysics. While optical telescopes may have presented a peek into the structure of the constituents of the universe, such as stars and galaxies, new windows of observation have revealed far more amorphous objects, from nebulae and sheets to filaments and voids, whose "violent" processes include flares, shocks, accretion disks and jets. In these processes, plasma is often the constituent matter-- as well as the medium through which the astrophysical setting becomes so violent. In this graduate level text, Tajima and Shibata offer a new synthesis starting where classic works on plasma physics left off. Beginning with a view of plasma astrophysics through fundamental processes of quasi-magnetostatic equilibria, quasi-hydrostatic equilibria, and non-equilibria, the authors go on to develop unique approaches to violent astrophysical plasmas-- as opposed to the more quiescent laboratory variety-- and their processes. The text continues with an exploration of the fundamental processes in hydrostatic, magnetostatic, and gravitational objects. The final chapter is devoted to a discussion of the applications of plasma astrophysics to cosmology, anticipating future developments in this exciting field.This text will be of enormous use to graduate-- and some advanced undergraduate-- students, as well as to physicists entering the field of plasma physics.

Plasma Atomic Physics (Springer Series on Atomic, Optical, and Plasma Physics #104)

by Frank B. Rosmej Valery A. Astapenko Valery S. Lisitsa

Plasma Atomic Physics provides an overview of the elementary processes within atoms and ions in plasmas, and introduces readers to the language of atomic spectra and light emission, allowing them to explore the various and fascinating radiative properties of matter. The book familiarizes readers with the complex quantum-mechanical descriptions of electromagnetic and collisional processes, while also developing a number of effective qualitative models that will allow them to obtain adequately comprehensive descriptions of collisional-radiative processes in dense plasmas, dielectronic satellite emissions and autoionizing states, hollow ion X-ray emissions, polarized atoms and ions, hot electrons, charge exchange, atomic population kinetics, and radiation transport. Numerous applications to plasma spectroscopy and experimental data are presented, which concern magnetic confinement fusion, inertial fusion, laser-produced plasmas, and X-ray free-electron lasers’ interaction with matter. Particular highlights include the development of quantum kinetics to a level surpassing the almost exclusively used quasi-classical approach in atomic population kinetics, the introduction of the recently developed Quantum-F-Matrix-Theory (QFMT) to study the impact of plasma microfields on atomic populations, and the Enrico Fermi equivalent photon method to develop the “Plasma Atom”, where the response properties and oscillator strength distribution are represented with the help of a local plasma frequency of the atomic electron density.Based on courses held by the authors, this material will assist students and scientists studying the complex processes within atoms and ions in different kinds of plasmas by developing relatively simple but highly effective models. Considerable attention is paid to a number of qualitative models that deliver physical transparency, while extensive tables and formulas promote the practical and useful application of complex theories and provide effective tools for non-specialist readers.
