The relationships between parrotfish groups and human population density at 18 reefs across the Indo-Pacific. Reefs from left to right are Carter, Hilder, Rowley Shoals, Hicks, Day, Yonge, Kavieng, Binnegem, Togean Islands, Cocos-Keeling, Kosrae, Pohnpei, Moorea, Apia, Nu'utele, Tahiti, Rodrigues and Mauritius. The functionally similar Scarus and the rarer Hipposcarus are combined, whereas the functionally different large and small Chlorurus species are separated. The fitted trend lines are inverse polynomials, with the exception of small Cholurus which is quadratic.
