The Antarctic Conservation Biogeographic Regions (ACBRs) as defined in Terauds and Lee (2016). We examined a total of 988 samples from 10 ACBRs. These 10 ACBRs are shown in bold. ACBRs 2, 5, 11, 13, 14, and 15 were not represented in the sampling. Sample locations are indicated with white dots. The number of samples collected from each ACBR is reported in parentheses, followed by the number of samples collected from islands in each ACBR. Twenty-four samples collected from islands associated with mainland Antarctica, and sub- and peri-Antarctic islands are not included in the ACBR classification
