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.

4.4 AERIAL SURVEYS OF WILDLIFE POPULATIONS Many wildlife surveys are
carried out by aerial census, a specialized form of quadrat sampling. Aerial
surveying is discussed in detail in Norton-Griffiths (1978), and I will discuss here
LeResche and Rausch concluded that aerial counts were not valid estimates of
absolute moose numbers because of the large counting bias. Caughley (1974)
listed 17 analyses of the accuracy of aerial censusing for large mammals, and the
This list is clearly not exhaustive. Bayliss and Giles (1985) showed that ambient
temperature affected kangaroo counts very strongly, and Broome (1985) showed
that different bird species did not react the same to aerial counts. Gasaway et al.
