This coherent text translates the methods of statisticians into "ecological English" so that students may readily apply these methods to the real world. Ecological Methodology, Second Edition provides a balance of material on animal and plant populations. It teaches students of ecology how to design the most efficient tests in order to obtain maximum precision with minimal work. The first part of the text focuses on biological and technical issues in statistical methodology. Students learn about advances that have been made in designing better sampling devices, along with the techniques and equipment used for sampling. The second part deals with creating solid statistical design, and presents all methods that are well-known to statisticians in a language and context that students will easily understand.

This book is largely concerned with the descriptive statistics of ecology and the
types of sampling schemes that ecologists can adopt. For example, the
conceptually simple variable population size is difficult to measure, and yet is
vital for most ...
The conventional approach to a statistical test is too often presented as a black-or
-white decision whether to accept or reject the null hypothesis. We would be
better off if we viewed this problem of statistical decisions as an area of shades of
Should samplers be placed randomly or systematically? Should different habitats
be sampled separately or all together? These are the general statistical
questions I will address in this and the next chapter. I will develop a series of
