Softcover. Zustand: Fair. Verschmutzung; Leichte Verformung / umgeknickte Seiten. The impetus for this book arose from my previous work, which included a chapter on quantitative genetic theory. While that book focused on the evolution of life histories and related traits, quantitative genetic variation was a recurring theme. Much emphasis was placed on optimality theory, a successful method for analyzing life history variation. However, there are questions where optimality approaches fall short, particularly regarding genetic variation, which is crucial for further evolution. This book serves as a natural extension of the first, approaching the topic from the perspective of understanding the evolution of quantitative traits in wild populations rather than from a breeding standpoint. The subject is extensive, supported by a substantial body of research. I present the underlying assumptions and results, along with references for those interested in the mathematics involved. My focus is on what quantitative genetics reveals about evolutionary processes, concentrating on research areas most relevant to field studies.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This 2006 guide to the contemporary toolbox of methods for data analysis will serve graduate students and researchers across the biological sciences. Modern computational tools, such as Maximum Likelihood, Monte Carlo and Bayesian methods, mean that data analysis no longer depends on elaborate assumptions designed to make analytical approaches tractable. These new 'computer-intensive' methods are currently not consistently available in statistical software packages and often require more detailed instructions. The purpose of this book therefore is to introduce some of the most common of these methods by providing a relatively simple description of the techniques. Examples of their application are provided throughout, using real data taken from a wide range of biological research. A series of software instructions for the statistical software package S-PLUS are provided along with problems and solutions for each chapter.…
