Figure 4
The figure consists of two density line graphs placed one above the other. The details of the top graph are as follows: The horizontal axis is labeled “Willingness to pay in euros” and ranges from 0 to 15 in increments of 5 units. The vertical axis is labeled “Density” and ranges from 0.00 to 0.12 in increments of 0.04 units. The graph shows two curves. At the top right, the legend identifies a red solid curve labeled “M P A establishment did not influence decision to dive” and a green dashed curve labeled “M P A establishment influenced decision to dive”. The red curve starts at (negative 3.62, 0), rises in a concave-down manner and peaks at (6.88, 0.11), then gradually declines, passing through multiple points forming sharp peaks and troughs, and ends at (18.68, 0). The green dashed curve begins at (negative 3.73, 0), follows a similar pattern but remains slightly below the red curve throughout, peaks at (6.81, 0.10), passes through several points forming sharp peaks and troughs, and ends at (18.71, 0.01). The details of the bottom graph are as follows: The horizontal axis is labeled “Willingness to pay in euros” and ranges from 0 to 15 in increments of 5 units. The vertical axis is labeled “Density” and ranges from 0.00 to 0.12 in increments of 0.04 units. The graph also shows two curves. At the top right, the legend identifies a red solid curve labeled “M P A does not ensure ecosystem conservation” and a green dashed curve labeled “M P A ensures ecosystem conservation”. The red curve starts at (negative 3.66, 0.01), rises in a concave-down manner and peaks at (1.56, 0.11), then gradually declines, passing through multiple points forming sharp peaks and troughs, and ends at (18.69, 0). The green dashed curve begins at (negative 3.74, 0.00), rises in a concave-down manner and peaks at (6.93, 0.11), then gradually declines, passing through several points forming sharp peaks and troughs, and ends at (18.69, 0). Note: All numerical data values are approximated.Sample distribution of the WTP, conditional to the importance attached to the establishment of an MPA when choosing the diving site (top panel) and the relevance given to MPAs for ecosystem conservation (bottom panel)
