This involved calculating the numbers of species
shared by each pair of stations. The general pattern
was as expected, in that each site shares the greatest
number of species with the closest other region
and fewest species with the most remote region
(Tables
6.6
and
6.7
). For example, station I shares
occur at only three stations, i.e., 11 % species
occur at three stations. Twenty-three species
occur at only two stations, thus showing that
38.98 % of the species can be found at only two
stations.
