Ordination of the first and second constrained axes of RDA of the relationships between diet composition of lizard individuals and 4 explanatory variables (arrows): sex (female, juvenile, and male), season (autumn, spring, and summer), body length and body weight in the islets NM (left), and NG (right). Symbols indicate lizard individuals (squares) and food items (triangles). Colors of squares indicate the season in which the lizard was captured and colors of the triangles indicate the type of food item (see legend). Only Axis 1 and the explanatory variable season significantly influenced the ordination.
