Figure 1. Graphs generated by the Phenological Predictability Index (PPI) tool in BRAHMS, which calculates the probability of a specific phenophase (in this case, flower buds) occurring in each month of the year (1, January, to 12, December): A, Ruellia incompta (unimodal phenology); B, Emmotum nitens (bimodal phenology); and C, Dalechampia caperonioides (multimodal phenology). The y-axis shows the number of unique records (each a unique combination of phenological event, month and year). The month with the highest peak in the graph may differ from the PPI-determined maximum probability month (circled); see text for explanation.
