a, Estimated proportional contribution of mimosa to the diets of six dominant floodplain ungulate species in Gorongosa between 2013 and 2018, indexed by the RRA of mimosa DNA sequences in faecal samples. The bars show the mean (±1 s.e.m.) RRA across all faecal samples from each species in each year (sample sizes are shown above the bars). b, Frequency of occurrence of mimosa in the same set of faecal samples. This metric reflects the proportion of samples that contained mimosa DNA (presence–absence); a 1% threshold of RRA was used to infer that mimosa DNA was present in a sample59. Sample sizes match those in a. Quantitative comparisons between years should be interpreted cautiously, as samples from different years were processed and sequenced separately (see Methods); nonetheless, the data show that mimosa was an abundant and frequent forage of all five ruminant species in each year sampled. The top three food-plant taxa for each LMH species in each year are shown in Extended Data Fig. 1. Comparisons of mimosa consumption in the early versus late dry season are shown in Extended Data Fig. 2. Illustrative video footage of waterbuck and oribi eating mimosa is presented in Supplementary Videos 1 and 2.
