Figure 2. Spline plot generated by Generalized Additive Mixed Models (GAMM), which illustrates the temporal increase and decrease in precipitation (blue dashed line) and frugivory (gray spline with credible intervals). Black points represent each fecal sample and the colored rectangles in the background represent the calendar seasons. The horizontal axis is the number of calendar days elapsed in the year, the left vertical axis is the proportion of fecal volume comprised of fruit, and the right vertical axis is the average daily precipitation. Winter is blue, spring is green, summer is red, and fall is orange. The progressively lighter intervals surrounding each curve represent the Bayesian 50%, 80%, and 95% credible intervals.
