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.

If you wish to harvest a lake trout population, one helpful bit of information is the
size of the population you wish to harvest. If you are trying to ... Relative density is

All of the methods in this chapter and the previous chapter estimate population
size, and to convert this to population density, you must know the area occupied
by the population. This is simple for discrete populations on islands but difficult
