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.

Similarly, after you have estimated population size by the Petersen method and
calculated the confidence interval, the true population size (unfortunately not
known to you) will either be inside your confidence interval or outside it. You
In normal circumstances we try to equalize sample sizes so that M = C, the
number marked is approximately the same as the number caught in the second
Petersen sample. This balance of M = C is the point of minimum effort in terms of
affecting the validity of the Petersen estimate. If accidental deaths occur during
the first sampling and marking, the estimate of N is valid but refers to the number
of individuals alive in the population after the first sample is released. Natural ...
