From: Quadratic relationships between group size and foraging efficiency in a herbivorous primate

Group size versus the proportion of time that gorillas spent traveling (a) or feeding (b). For purposes of clarity, the results are aggregated into one data point for each group in each habitat, and data point with less than 100 scans are omitted. The size of each symbol reflects the sample size. The legend at the bottom of (b) indicates the group ID for each data point.
