FIG. 2 in Nest Attendance Patterns in the American Alligator (Alligator mississippiensis)

FIG. 2. Generalized additive model (GAM) analysis of alligator nest visitation varying over the incubation period in 2011 (A; v2 ¼ 64.31, r2 ¼ 0.07, P, 0.01) and 2012 (B; v2 ¼ 56.98, r2 ¼ 0.13, P, 0.01). Nests with an alligator present (1) or absent (0) are shown as binary classes (boxes) with darker shading indicating higher densities of observations. Binary data were used to calculate the proportion of nests with visits (circles). Nest attendance declined rapidly during the first weeks, remained low for the majority of incubation, and increased during
