Extended Data Fig. 8: Carnivore behavior before and after Cyclone Idai.
From: Trait-based sensitivity of large mammals to a catastrophic tropical cyclone
(a) Coefficients ± 95% CIs from step-selection functions (SSFs) fit to GPS telemetry data from African wild dog (the only pack present at the time of this study) and lion, showing selection for elevation, termite mounds, and distance to flood waters in the two weeks before (purple) and after (yellow) Idai (cf. Fig. 2a). (b) Both species exhibited moderate displacement from their ranges, moving away from Lake Urema in the weeks after landfall (yellow lines compare the week prior to 15 Mar. 2019 to weekly bins thereafter; thin, individuals; bold, population) relative to periods immediately before the cyclone (purple lines compare the week prior to 1 Feb. 2019 to weekly bins thereafter; cf. Fig. 2b). c–e, Whereas no shift in lion diet was detected, the proportion of waterbuck among confirmed wild dog kills increased after the cyclone (c; sample sizes for each time period at top). This shift was associated with a greater overall difference in wild dog diet composition before versus immediately after the cyclone as quantified using DNA metabarcoding and visualized here by nonmetric multidimensional scaling (NMDS) ordination of Bray Curtis dissimilarity values (d; markers correspond to individual fecal samples). Relative read abundance (RRA) of prey DNA in wild dog scats independently the general pattern observed in the kill data (e; means ± s.e.m.).
