Table 2.

Mean uncorrected p-distances for cox1 within and among clusters.

	among clusters		within clusters
	mean	range	mean	range
Canthon	0.115	0.099–0.125	0.005	0–0.010
water beetles	0.162	0.140–0.190	0.005	0–0.018

Singletons were included in the among-cluster calculation, but within-cluster p-distance could not be measured.
