Figure 3. (a) Ecological conditions (rainfall, young leaf and fruit availability) from Aug. 2017 to May 2019 with, (b) social network density measures, (c) node strength, and (d) the timing of male dispersal events in a band of Colobus angolensis ruwenzorii at Nabugabo, Uganda. Core unit associations levels are represented by (b) and (c). For (b) the shaded area represents the density range expected due to chance encounters, and was calculated using data-stream permutations using 95% CI.
