Figure 1 . Comparison of Colobus angolensis ruwenzoriicore units’ clan associations across years at Nabugabo, Uganda, depicted by dendrograms created using hierarchical cluster analysis (CCC = 0.891; SOCPROG: Whitehead, 2009). * indicates the movement of a core unit between clans. The “Year 1 – 2017-2018” dendrogram has been adapted from Fig.1a in Stead & Teichroeb, 2019.
When looking at shorter sample windows, cosine similarity values demonstrate the high amounts of temporal variability within the combined sample years (2017-2019), both in the short-term (Fig. 2a) and the long-term (Fig. 2b). When comparing each window to the first (Fig. 2b), cosine similarity ranges between ~0.12-0.51 (excluding the first month where cs = 1.0). The highest value of 0.51 was seen in the months of October and December 2017, and the lowest of 0.12 in April 2018. When comparing each window to the previous (Fig. 2a), cosine similarity ranges between ~0.15-0.61. The highest value of 0.61 was seen in the month of April 2019, and the lowest of 0.15 in November 2018.
