Figure 5. Correlations between mean productivity and both the SEA_c and the SDNND_b at the population-year level.

Mean productivity refers to A) only successful pairs and B) the whole monitored population (either successful or not successful breeding pairs). In both cases, the upper x-axis shows the SEA_c (corrected standard ellipse area; open symbols), and the lower x-axis shows the SDNND_b (standard deviation of nearest neighbour distance bootstrapped; filled symbols). Trend lines of the relationship between productivity and either SEA_c (solid line) or SDNND_b (dashed line) are shown. Different symbol shapes represent France (triangles), Catalonia (circles) and Andalusia (squares).
