Figure 3

Surface depicting the broad spatial pattern in homozygosity (HL) across Santa Cruz Island, based on a second-order polynomial trend analysis. Lighter colors correspond to locations with higher predicted HL values. White circles represent sample locations, the white cross depicts the geographic center of the island and lines show contours along the predicted HL surface. The darkest region—corresponding to locations with the lowest levels of homozygosity—roughly corresponds to the center of the island.
