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.

2.3 JOLLY-SEBER METHOD Both the Petersen and Schnabel methods are
designed for closed populations, and we now extend the mark-recapture
technique to the more biologically realistic situation of open populations. Most
2.3.2. Assumptions. of. the. Jolly-Seber. Method. The Jolly-Seber method is
designed for open populations, so unlike the earlier methods discussed in this
chapter we do not need to assume the absence of recruitment and mortality.
Seber (1982, 225) gives the large sample variance for the estimated Z values.
The square root of the variance of Z, can be used to judge the significance of the
differences between observed and estimated Z, values (Leslie et al. 1953, 149).
