I collected ants from May to September 1994 using a combination of visual searches, pitfall traps, and tuna & honey baits. During the course of the study I surveyed eight of the archipelago's 20+ islands, including the largest (Grand Manan, 140 km2) and the smallest (W. Green Is, <1 ha.).

Species richnesses within the archipelago correlate positively with island size (r2=.83, p=.004), and with the presence of forest cover (Mann Whitney U test, p=.021). Ant distribution may also be determined by climatic differences between the islands, differential dispersal abilities between ant species, and the dependence of the socially parasitic ants on their hosts.
