Figure 1

Spatiotemporal distribution of Audouin’s gull breeding patches at the Ebro Delta colony. White polygons represent the spatial distribution of potentially suitable breeding areas. Each annual image covers 60 km2. Green circles represent approximate locations of occupied patches and circle size is proportional to the number of individuals breeding in each patch. Predators were regularly present in the colony since 1997. Purple dashed lines represent the interphase between unmanaged dune vegetation (west) and human managed salt pans (east).
