        Plant Cells and Tissues, Second Edition

        by Nicholas Stephens, Series Editor: William G. Hopkins

        Plants comprise millions of cells that work together as tissues to move materials throughout the body, gather water and minerals from the soil, and convert carbon dioxide into sugar by using energy from the sun. Plant Cells and Tissues, Second Edition takes a focused approach to the study of plant processes by examining this subject from its smallest unit, the cell. This volume also answers questions such as: How do tiny seeds grow into towering trees? How do nettles deliver such painful stings? And how do roots know which way is down? Some of the topics discussed include interesting aspects of plant cell biology, such as cell division and what makes a plant wilt. It also highlights special adaptations that plants have made to survive in harsh environments, including the plant science behind the survival of the spiny cacti of deserts and the carnivorous insect traps of acidic bogs. This reference is a vital tool for students and teachers of plant biology.

        Plant Development, Second Edition

        by William G. Hopkins; Series Editor: William G. Hopkins

        A plant grows by taking in carbon dioxide from the air and water, as well as nutrients from the soil. Using light energy from the sun, a plant turns these simple materials into more complex organic molecules that add to its increasing size. Plant Development, Second Edition explores this natural process, from the plant as a single cell to a mature organism, giving students a reference point for their understanding of the complex changes in both form and function of a plant's development. This is a valuable tool for students and teachers of plant biology.

        Plant Biotechnology, Second Edition

        by William G. Hopkins; Series Editor: William G. Hopkins

        Over the past 25 years, terms like genetic modification, genetic engineering, recombinant DNA technology, and biotechnology have become commonplace in the news and in the public vocabulary. But biotechnology has in fact been practiced for thousands of years, with the aim of harnessing organisms for processing food and making useful products. Since the 1980s, however, recombinant DNA technology has given us the ability to modify organisms in the most fundamental way. The modification of plants by these new techniques has unleashed a storm of public controversy worldwide. Plant Biotechnology, Second Edition brings perspective to the discussion. Tracing the history of biotechnology, from its origins in antiquity through its foundations as a science in the work of Louis Pasteur to the birth of modern genetic engineering, this eBook describes traditional uses for plants, reveals how they are genetically engineered, and explains how new technology compares with conventional ways of generating new food plants. Readers will find that this accessible introduction dispels some of the myths surrounding genetic engineering, clearly presents the current impact and future potential of genetically modified plants, and provides a balanced look at the risks and benefits of biotechnology.

        Photosynthesis and Respiration, Second Edition

        by William G. Hopkins; Series Editor: William G. Hopkins

        The ultimate source of energy is the sun, and the portal through which this life force flows into the biosphere is carried out by green plants. As a result, all organisms—plants, animals, and microbes—use photosynthetic energy for their own needs. Photosynthesis and Respiration, Second Edition introduces the concept of plants as photosynthetic machines and follows the flow of energy and carbon through the natural processes of photosynthesis and respiration. The interaction between photosynthesis and the environment is explored throughout this volume, as well as the role that plants play in balancing the global carbon budget. This reference is a vital tool for students and teachers of biological processes.

        Forestry, Second Edition

        by Catherine L. Raven, Series Editor: William G. Hopkins

        For centuries, forests have provided humans and wildlife with shelter and food, but as the need for more wood products from trees increases, so too does the danger of losing the source of our natural wealth. Left untouched, forests provide beauty and recreation that continue to improve our quality of life, and it is our responsibility to take care of that which takes care of us. Forestry, Second Edition explores the science of forestry, from the types of trees and shrubs grown for commercial and medicinal use, to the impact of trees on the environment and human society. This reference is a vital tool for students and teachers of the natural world.

        Plant Diversity, Second Edition

        by J. Phil Gibson and Terri R. Gibson, Series Editor: William G. Hopkins

        Plants feed us, clothe us, provide us with the oxygen we breathe, and buffer our environment against change. In short, plants make life possible. Yet scientists estimate that more than 10 percent of the world's approximately 300,000 plant species are at risk of extinction, and huge swaths of tropical forests and other plant communities are being decimated daily. Plant Diversity, Second Edition surveys the world's plant diversity, from green algae through flowering plants, and presents the fascinating natural history and diversity of green plants in a taxonomic and evolutionary context. This title also asks and answers the questions: Why are there so many plant species in the world? And how can so many plants grow together in a given patch of prairie, forest, or wetland? Through the study of plant diversity, students will gain an appreciation of the natural world far beyond the classroom and the study of botany, to an understanding of how our actions impact the world around us. Plant Diversity, Second Edition is suitable as a supplementary text for a biology course or as recreational reading for the interested student.

        Practical R for Biologists

        An Introduction

        by Donald Quicke, Buntika A Butcher, Rachel Kruft Welton

        R is a freely available, open-source statistical programming environment which provides powerful statistical analysis tools and graphics outputs. R is now used by a very wide range of people; biologists (the primary audience of this book), but also all other scientists and engineers, economists, market researchers and medical professionals. R users with expertise are constantly adding new associated packages, and the range already available is immense.This text works through a set of studies that collectively represent almost all the R operations that biology students need in order to analyse their own data. The material is designed to serve students from first year undergraduates through to those beginning post graduate levels. Chapters are organized around topics such as graphing, classical statistical tests, statistical modelling, mapping, and text parsing. Examples are based on real scientific studies, and each one covers the use of more R functions than those simply necessary to get a p-value or plot.The book walks the reader through the data analysis process, starting with very simple plots, and continuing through more complex analyses and programming. It shows how to deal with issues such as error messages that can be confronting for beginners, in order to set students up for a successful scientific career using R.Collectively the authors have a vast amount of teaching experience which they apply here to make the passage into R programming as gentle and easy as possible, whilst guiding the reader to tackle quite complicated programming. Table of contents 1: How to Use this Book 2: Installing and Running R 3: Very Basic R Syntax 4: First Simple Programs and Graphics 5: The Dataframe Concept 6: Plotting Biological Data in Various Ways 7: The Grammar of Graphics Family of Packages 8: Sets and Venn diagrams 9: Statistics: Choosing the Right Test 10: Commonly Used Measures and Statistical Tests 11: Regression and Correlation Analyses 12: Count Data as Response Variable 13: Analysis of Variance (ANOVA) 14: Analysis of Covariance (ANCOVA) 15: More Generalised Linear Modelling 16: Monte Carlo Tests and Randomisation 17: Principal Components Analysis 18: Species Abundance, Accumulation and Diversity Data 19: Survivorship 20: Dates and Julian Dates 21: Mapping and Parsing Text Input for Data 22: More on Manipulating Text 23: Phylogenies and Trees 24: Working with DNA Sequences and other character data 25: Spacing in Two Dimensions 26: Population Modelling Including Spatially Explicit Models 27: More on “apply” Family of Functions – Avoid Loops to get More Speed 28: Food webs and simple graphics 29: Adding Photographs 30: Standard Distributions in R 31: Reading and Writing Data to and from Files

        Intentionalität

        Eine Abhandlung zur Philosophie des Geistes

        by Harvey P. Gavagai, John R. Searle

        Nach seinen sprachphilosophischen Arbeiten ('Sprechakte', stw 458; 'Ausdruck und Bedeutung', stw 349) hat John R. Searle mit 'Intentionalität' eine Untersuchung zu einem Kernstück der Philosophie des Geistes vorgelegt, die in einem engen thematischen Zusammenhang mit den früheren Arbeiten steht. Intentionalität ist nach Searles Auffassung die Basis sprachlicher Bedeutung. In seiner Theorie der Intentionalität geht es um die begrifflichen Eigenschaften intentionaler Zustände (auf die Frage nach ihrem ontologischen Status geht er ausführlicher ein in 'Geist, Hirn und Wissenschaft', stw 591). Zwei Aspekte stehen dabei im Vordergrund der Untersuchung: die Logik der Repräsentation und der Kausalität intentionaler Zustände. Doch Searle entwickelt in dieser Arbeit nicht nur eine Theorie der Intentionalität und des Zusammenhangs zwischen sprachlichem und geistigem Inhalt. In einem vornehmlich kritischen Teil setzt er sich ausführlich mit konkurrierenden Auffassungen aus dem Bereich der analytischen Philosophie auseinander, insbesondere mit derzeit sehr einflußreichen 'nicht-deskriptivistischen' Theorien des Bezugs, wie sie von S. Kripke, H. Putnam, K. Donnellan, T. Burge und D. Kaplan vertreten und angeregt wurden.
