Spatial distribution of a) pups and b) adults (squares represent males), showing strong separation of A. gazella (blue for females and pups, dark green for males, Q
≥ 0.9) and A. tropicalis (red for females and pups, light green for males, Q
≤ 0.1) across the four main breeding aggregations, with habitat type (P = pebbles, B = boulders) in parentheses. The transition zone between habitat types is shaded and illustrates the relatively high density of hybrid pups and females (purple for females and pups, yellow for males). The hybrid threshold is bounded by a horizontal, dashed line and includes all pups with Q
between 0.1 and 0.9).
