R is now the most widely used statistical software in academic science and it is rapidly expanding into other fields such as finance. R is almost limitlessly flexible and powerful, hence its appeal, but can be very difficult for the novice user. There are no easy pull-down menus, error messages are often cryptic and simple tasks like importing your data or exporting a graph can be difficult and frustrating. Introductory R is written for the novice user who knows a little about statistics but who hasn't yet got to grips with the ways of R. This new edition is completely revised and greatly expanded with new chapters on the basics of descriptive statistics and statistical testing, considerably more information on statistics and six new chapters on programming in R. Topics covered include: A walkthrough of the basics of R's command line interface Data structures including vectors, matrices and data frames R functions and how to use them Expanding your analysis and plotting capacities with add-in R packages A set of simple rules to follow to make sure you import your data properly An introduction to the script editor and advice on workflow A detailed introduction to drawing publication-standard graphs in R How to understand the help files and how to deal with some of the most common errors that you might encounter. Basic descriptive statistics The theory behind statistical testing and how to interpret the output of statistical tests Thorough coverage of the basics of data analysis in R with chapters on using chi-squared tests, t-tests, correlation analysis, regression, ANOVA and general linear models What the assumptions behind the analyses mean and how to test them using diagnostic plots Explanations of the summary tables produced for statistical analyses such as regression and ANOVA Writing your own functions in R Using table operations to manipulate matrices and data frames Using conditional statements and loops in R programmes. Writing longer R programmes. The techniques of statistical analysis in R are illustrated by a series of chapters where experimental and survey data are analysed. There is a strong emphasis on using real data from real scientific research, with all the problems and uncertainty that implies, rather than well-behaved made-up data that give ideal and easy to analyse results.

The application and interpretation of statistics are central to ecological study and practice. Ecologists are now asking more sophisticated questions than in the past. These new questions, together with the continued growth of computing power and the availability of new software, have created a new generation of statistical techniques. These have resulted in major recent developments in both our understanding and practice of ecological statistics. This novel book synthesizes a number of these changes, addressing key approaches and issues that tend to be overlooked in other books such as missing/censored data, correlation structure of data, heterogeneous data, and complex causal relationships. These issues characterize a large proportion of ecological data, but most ecologists' training in traditional statistics simply does not provide them with adequate preparation to handle the associated challenges. Uniquely, Ecological Statistics highlights the underlying links among many statistical approaches that attempt to tackle these issues. In particular, it gives readers an introduction to approaches to inference, likelihoods, generalized linear (mixed) models, spatially or phylogenetically-structured data, and data synthesis, with a strong emphasis on conceptual understanding and subsequent application to data analysis. Written by a team of practicing ecologists, mathematical explanations have been kept to the minimum necessary. This user-friendly textbook will be suitable for graduate students, researchers, and practitioners in the fields of ecology, evolution, environmental studies, and computational biology who are interested in updating their statistical tool kits. A companion web site provides example data sets and commented code in the R language.

Full of biological applications, exercises, and interactive graphical examples, Foundational and Applied Statistics for Biologists Using R presents comprehensive coverage of both modern analytical methods and statistical foundations. The author harnesses the inherent properties of the R environment to enable students to examine the code of complicated procedures step by step and thus better understand the process of obtaining analysis results. The graphical capabilities of R are used to provide interactive demonstrations of simple to complex statistical concepts. Assuming only familiarity with algebra and general calculus, the text offers a flexible structure for both introductory and graduate-level biostatistics courses. The first seven chapters address fundamental topics in statistics, such as the philosophy of science, probability, estimation, hypothesis testing, sampling, and experimental design. The remaining four chapters focus on applications involving correlation, regression, ANOVA, and tabular analyses. Unlike classic biometric texts, this book provides students with an understanding of the underlying statistics involved in the analysis of biological applications. In particular, it shows how a solid statistical foundation leads to the correct application of procedures, a clear understanding of analyses, and valid inferences concerning biological phenomena. Web Resource An R package (asbio) developed by the author is available from CRAN. Accessible to those without prior command-line interface experience, this companion library contains hundreds of functions for statistical pedagogy and biological research. The author’s website also includes an overview of R for novices.

Maps of species' distributions or habitat suitability are required for many aspects of environmental research, resource management and conservation planning. These include biodiversity assessment, reserve design, habitat management and restoration, species and habitat conservation plans and predicting the effects of environmental change on species and ecosystems. The proliferation of methods and uncertainty regarding their effectiveness can be daunting to researchers, resource managers and conservation planners alike. Franklin summarises the methods used in species distribution modeling (also called niche modeling) and presents a framework for spatial prediction of species distributions based on the attributes (space, time, scale) of the data and questions being asked. The framework links theoretical ecological models of species distributions to spatial data on species and environment, and statistical models used for spatial prediction. Providing practical guidelines to students, researchers and practitioners in a broad range of environmental sciences including ecology, geography, conservation biology, and natural resources management.

Providing an interface between dry-bench bioinformaticians and wet-lab biologists, DNA Methylation Microarrays: Experimental Design and Statistical Analysis presents the statistical methods and tools to analyze high-throughput epigenomic data, in particular, DNA methylation microarray data. Since these microarrays share the same underlying principles as gene expression microarrays, many of the analyses in the text also apply to microarray-based gene expression and histone modification (ChIP-on-chip) studies. After introducing basic statistics, the book describes wet-bench technologies that produce the data for analysis and explains how to preprocess the data to remove systematic artifacts resulting from measurement imperfections. It then explores differential methylation and genomic tiling arrays. Focusing on exploratory data analysis, the next several chapters show how cluster and network analyses can link the functions and roles of unannotated DNA elements with known ones. The book concludes by surveying the open source software (R and Bioconductor), public databases, and other online resources available for microarray research. Requiring only limited knowledge of statistics and programming, this book helps readers gain a solid understanding of the methodological foundations of DNA microarray analysis.

John Alcocks Standardwerk Animal Behavior - jetzt in Form eines völlig neuen Lehrbuchtyps, der speziell für die Studiensituation im deutschsprachigen Raum konzipiert wurde.* Das erfolgreiche Lehrbuch Animal Behavior stellt die verschiedenen Aspekte tierischen Verhaltens in einen evolutionsbiologischen Rahmen. Es behandelt die grundlegenden Mechanismen des Verhaltens ebenso wie seine stammesgeschichtlichen Ursachen und betont die Bedeutung der Evolutionstheorie als einigendes Element der unterschiedlichen Teildisziplinen der Verhaltensbiologie. Wichtige Konzepte werden sowohl an Wirbellosen wie an Wirbeltieren verdeutlicht. Alcocks klarer und engagierter Schreibstil macht es auch Anfängern trotz der stark konzeptionellen Ausrichtung des Werkes leicht, den Stoff zu verstehen. Die nun vorliegende achte Auflage des Standardwerkes wurde völlig neu geschrieben. Zahlreiche Erkenntnisse aus jüngster Zeit haben darin Eingang gefunden. Verständnisfragen direkt an den entsprechenden Textstellen regen dazu an, sich mit dem gerade gelesenen Stoff auseinanderzusetzen. Die beiden Kapitel über die Einflüsse von Vererbung und Umwelt auf die Entwicklung wurden vereint, um zu verdeutlichen, dass Entwicklungsprozesse sowohl von genetischen als auch von Umweltfaktoren abhängen. Der Autor führt dem Leser immer wieder vor Augen, welche Rolle der Überprüfung von Theorien und Hypothesen zukommt und dass wissenschaftliche Schlussfolgerungen immer nur vorübergehend gültig sind. So werden in diesem Buch auch kontrovers diskutierte und bisher ungelöste Probleme angesprochen. * Von Studierenden der Biowissenschaften wird heute erwartet, dass sie im Laufe ihres Studiums englische Literatur problemlos lesen und verstehen und schließlich auch Forschungsergebnisse auf Englisch kommunizieren können. Den Weg dorthin bereitet der neu entwickelte Lehrbuchtyp Easy Reading - Das Original mit Übersetzungshilfen. So bietet die vorliegende Ausgabe von Animal Behavior in einem zusammen: den englischen Originaltext deutsche Übersetzungshilfen in der Randspalte deutschsprachige Verständnisfragen / Übungsaufgaben ein englisch-deutsches Glossar deutsch- und englischsprachige Kapitelzusammenfassungen und auf der Website www.elsevier.de/alcock: eine Übersicht über die im Buch erwähnten Arten (deutsch, englisch, lateinisch) Internetlinks für Deutschland, Österreich und die Schweiz Wesentlicher Zusatznutzen der "Easy Reading"-Ausgabe ist, das Lesen des englischen Grundtextes zu erleichtern und in die spezielle wissenschaftliche Terminologie einzuführen. Wer dieses Buch durcharbeitet, steigert somit seine fachliche und seine sprachliche Kompetenz zugleich. This new edition of Animal Behavior has been completely rewritten with coverage of much recent work in animal behavior, resulting in a thoroughly up-to-date text. Notable is the inclusion, for the first time, of discussion questions embedded in the text itself, rather than appended to the end of each chapter. This format is designed to encourage students to reflect on the material they have just digested while also making it easier for instructors to promote a problem-solving approach to the subject in their classes. Another key organizational improvement is the consolidation of what had been two separate chapters on the genetic and environmental influences on development. By combining this material, the new Chapter 3 makes a stronger, more tightly argued case for the view that development is a truly interactive process codependent on both genetic and environmental factors. Like previous editions, the book shows how evolutionary biologists analyze all aspects of behavior. It is distinguished by its balanced treatment of both the underlying mechanisms and evolutionary causes of behavior, and stresses the utility of evolutionary theory in unifying the different behavio

Sammler des verlorenen Schatzes. Ein waghalsiger Forscher begibt sich auf eine der abenteuerlichsten Expeditionen, die es je gab: Alfred Russel Wallace und seine Forschungsreise ins Amazonasgebiet. Auf eigene Faust bricht der Naturenthusiast Alfred Russel Wallace im Jahr 1848 von England nach Brasilien auf, um die Tier- und Pf lanzenwelt am Amazonas zu erforschen. Wallace schlägt sich von Pará (heute Belém) aus zu den Oberläufen des Rio Negro durch – und gelangt dabei in Gegenden, die noch kein Europäer vor ihm betreten hatte. Die Beobachtung der Affen- und Schmetterlingsarten an beiden Flussufern bringt ihn erstmals auf die Spur der Evolutionstheorie, die er später zeitgleich mit Charles Darwin entwickeln wird. Die Erträge seiner Expedition sind großartig, das Unternehmen endet jedoch in einer Katastrophe: Von Krankheiten, Sandf löhen (die ihre Eier unter seine Zehennägel legen) und den ewigen Kriebelmücken geplagt, ist Wallace am Ende so ausgezehrt, dass er nur mit der Hilfe der Einheimischen überlebt. Die aber trinken den Alkohol, mit dem eigentlich die Fundstücke konserviert werden sollten; und Horden von Ameisen machen sich über die Sammlung her. Auf dem Rückweg setzt Wallace alles auf eine Karte: Er selbst, seine Aufzeichnungen und Zigtausende Sammlungsstücke treten auf dem Zweimaster Helen die Heimreise an. Auf hoher See bricht an Bord ein Feuer aus. Die Besatzung kann sich auf Beiboote retten. Doch für Wallace’ Sammlung, auch für die lebenden Affen und Vögel, die in England an Zoos und Sammler verkauft werden sollten, gibt es keine Rettung. Nur einen einzigen Papagei kann Wallace lebend aus dem Wasser fischen. Der gesamte Ertrag seiner Reise versinkt in den Fluten des Ozeans. Zurück in England, rekonstruiert Wallace seine Erlebnisse anhand von wenigen Notizen und Erinnerungen. Seinen Reisebericht, sowohl Abenteuerroman, Forschungsgeschichte und frühes Zeugnis der Suche nach dem Ursprung der Arten, gab es auf Deutsch nur 1855 in einer stark verstümmelten Fassung – nun, nach über 150 Jahren, wird er endlich für die deutschsprachige Leserschaft erschlossen!

Yawning is a stereotyped phylogenetically ancient phenomenon that occurs in almost all vertebrates. As an emotional behavior and an expressive movement, yawning has many consequences; nevertheless, it has so far been poorly addressed in medical research and practice. Bringing together the latest research from many fields, this volume integrates current insights within embryology, ethology, neurophysiology, psychology, fMRI and pathology. The phylogenetic and ontogenetic aspects of yawning offer an interesting perspective on human development, and its occurrence in neurological diseases - an area explored by only a few investigators - may provide useful clinical information. This book will make valuable and fascinating reading to neurologists, sleep specialists, psychologists, ethologists and pharmacologists, as well as to anybody interested in uncovering the mystery of yawning.
