Fig 4
Box-plots (bold midline indicates the median, the upper and lower limits of the box represent the third and first quartiles) of observed baboon cluster sizes during seasonal (LR: Long rains; Dry: Dry season; SR: Short rains) line distance surveys in Lake Manyara National Park (Tanzania). The jittered grey points indicate observed cluster sizes.
