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.

Rarefaction is a statistical method forestimating the number of species expected
in a random sample of individuals taken from a collection. Rarefaction answers
this question: If the sample had consisted of n individuals (n → N), what number
Number of individuals alive at end of time period Number of individuals alive at
start of time period (14.1) N S., - ot 0. No Finite survival rate = If the time interval is
one year, this will give a finite annual survival rate. Finite survival rates can range
