(‘HostD2’)

Comparisons were calculated between three different habitats (‘Back Reef’, ‘Upper Slope’, ‘Deep Slope’) at two locations on the northern GBR (Day Reef, Yonge Reef). The last population consists of the individuals from the ‘Deep Slope’ habitat at Yonge Reef with a ‘HostD2’ mtDNA genotype. Values in bold indicate pairwise values between the same habitats at different locations.
