Population turnover is a measure of the number of new appearances and extinctions in each sample, and population diversity is calculated as number of species per hundred specimens and expressed as a percentage. Population similarity is calculated between adjacent samples in the sequence as number of species common to the two samples/total number of species in both samples x 100. Fluctuations in population similarity will give an assessment of population stability—a sequence of highly similar samples will denote a stable population, and vice versa. Note that in all cases, percentage of species and higher taxa quoted in this figure and in the text are based on three-point running mean Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
