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.

Abundance. in. Animal. and. Plant. Populations. How many are there? This
question is the central question of many ecological studies. If you wish to harvest
a lake trout population, one helpful bit of information is the size of the population
A guide to the intensity of sampling required to attain reliable data is provided for
open populations. High capture probabilities are typically needed to obtain
reliable data. For many organisms, there are easier ways of estimating
Calculate the average abundance of each of the networks: k X yi w; (8.35) m,
where w, = Average abundance of the i-th network y, = Abundance of the
organism in each of the k quadrats in the i-th network m, = Number of quadrats in
the i-th ...
