There is growing recognition that ecological systems are so complex that major advances will only come as techniques are developed for analysing networks of variables, rather than by the more traditional approach of looking at one response variable at a time.
This new textbook for students and researchers in ecology explains how to study multivariate hypotheses, with a focus on structural equation modelling and iterative partial least squares analysis. Covering topics such as the way that research questions are posed, data is collected and conclusions are drawn, this book critically examines the adequacy of the methodological paradigms currently used by ecologists, whilst posing questions about the future of multivariate methodology and how developments will advance our understanding.
