TABLE 2.

Permutational multivariate analyses of variance (PERMANOVA) of the genetic distances between Siphamia tubifer hosts and between their light organ symbionts.

	Host					Symbiont
Dataset	DF	SS	F	R	P	DF	SS	F	R	P
2014	3	15694	1.004	0.032	0.343	3	0.523	1.597	0.050	<0.001
2013	9	47367	1.008	0.054	0.131	9	1.099	1.249	0.064	<0.001
Sesoko	2	10718	1.027	0.038	0.033	2	0.225	1.092	0.043	0.093

For each dataset the degrees of freedom (DF), sum of squares (SS), predicted F-value (F), R² (R), and P-value are shown. For the 2014 and 2013 datasets, sampling location was used as the grouping factor, whereas sampling year was used for the Sesoko dataset. Significant P-values are in bold.
