Figure 3: Isolation-by-distance patterns in Porites astreoides.
From: Long distance dispersal and vertical gene flow in the Caribbean brooding coral Porites astreoides
Geographic distance explained 17% of the variation in genetic distance (FST) across all sampling sites (R2 = 0.17, P < 0.01, Fig. a), 39% of the variation in genetic distance when the U.S. Virgin Islands sites were excluded (R2 = 0.39, P < 0.01, Fig. b), and none of the variation when Bermuda sites were excluded (R2 = 0.01, P > 0.05, Fig. c).
