From: Wild chimpanzee termite mound inspections converge with the onset of rain
(A) The effect of cumulative rainfall on the binary outcome of whether a chimpanzee inspected a termite mound for termite-fishing viability. (B) The effect of average weekly rainfall on whether a chimpanzee inspected a termite mound for termite-fishing viability. Shaded bands represent 95% confidence intervals. Points are jittered in order to view number of observations. Interaction between rainfall terms has a significant effect on probability of inspection behavior. Probability of inspection increases with initial seasonal rains and increased average weekly rainfall but then decreases as rainfall continues to accumulate and the weekly average rainfall increases. Inspection probability decreases into the late wet season and there is less precision in probability estimates at the highest range of average weekly rainfall.
