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.

The question of whether mortality falls equally on marked and unmarked animals
is difficult to answer for any natural population, and this assumption is best
avoided if possible. Population size (N) in a mark-recapture estimation always
If the traps used are attractive to animals, so that individuals are attracted into the
study area, the assumption that the population is closed will be violated, and this
method should not be used. If a removal study is being conducted, and the ...
The basic assumption of this estimator is that there is a fixed flushing distance r
such that if an observer comes closer than runits to the animal, it flushes and is
observed. This is a restrictive assumption because it assumes that the detection ...
