Figure 5:

Changes in mean values of ghrelin (in picograms per millilitre) and leptin (in nanograms per millilitre) in reproductive female hawksbill turtles grouped by total number of nests observed in Rio Grande do Norte, Brazil. The values for ghrelin (A) increased significantly with an increasing number of nesting events, whereas the values for leptin (B) decreased considerably throughout the period (P < 0.05 by Wilcoxon test for all groups, except for the turtles that nested five times and turtles that nested once). Sample sizes are as follows: five nests, n = 3; four nests, n = 4; three nests, n = 7; two nests, n = 13; and one nest, n = 14.
