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.

Sample error: Long, thin transects usually reduce the variance of counts
whenever a clumped distribution is being sampled, as discussed previously, and
quadratshape arguments thus favor transect sampling. • Fatigue: Flying in a
straight line ...
To estimate population density from the change-in-ratio estimator discussed
previously in Chapter 3 (Section 3.1.1), you should consult Paulik and Robson (
1969) and Figures 3.1 and 3.2. These graphs will allow you to select the required
There is a bias in the methods discussed here toward the larger vertebrates. The
simplest measures of survival are obtained by following a group of individuals
over time. This gives us the finite survival rate: Number of individuals alive at end
