3 lists 10 diverse studies of vertebrate social structure published over the last 25 years. It includes birds, fish, and mammals ranging in size from chickadees to sperm whales. There are aquatic, aerial, and terrestrial species. These studies took place on the lands or waters of nine nations and examined free-living, provisioned, and captive animals. In one case, there was an experimental component to the study. The studies ranged very considerably in scale, with 9 to 1,767 animals being identified individually through a variety of methods over spatial spans ranging from 4 m to 200 km.

Then, for each permutation, sexes are scrambled so that there are the same number of males and females as in the real data but individuals may be of the opposite sex. Groups of mixed sex are then discarded and the difference in mean group sizes between those containing only males and those containing only females is calculated, giving one random value of the test statistic. 014. Permutation tests are discussed in some detail by Manly (1997). Technical issues that need considering include how many permutations to carry out.

5. subjects start in the same cluster, which is then split into two (often by K-means), and these are then split, and so on, until each subject is in its own cluster. In contrast, in agglomerative cluster analysis, “distances” are calculated between all subjects to be clustered. These can be dissimilarities, or inverse similarities. Each subject starts out in a cluster by itself, then the two clusters with the smallest distance between them are joined, and then the next two, and so on, until all subjects are in the same cluster.
