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.

Thus one could use linear regression techniques to obtain an estimate of the
slope (1/N) and thus an estimate of population size. ... (R,M,) where s = Total
number of samples The variance of the Schumacher estimator is obtained from
H = 0725 Having calculated these values, as shown in Table 2.8, we can obtain
the desired estimate: - 7. – m. 4 M z - (*#) – H + d, ... The actual Z, values can be
obtained from Table 2.3 as + 1 = 18.6 voles Z = s, - m, and are respectively 30, 45
