Extended Data Fig. 3: Body sizes and movement behaviors of bushbuck that died (n = 3) and survived (n = 5) Cyclone Idai.
From: Trait-based sensitivity of large mammals to a catastrophic tropical cyclone
a–b, The three bushbuck that died in the flood were smaller than the survivors (a) and included the two smallest of five adult females and the single smallest of three adult males (b). Boxplots show median and interquartile range; whiskers show minimum and maximum. (c) Coefficients ± 95% confidence intervals (CIs) from step-selection functions (SSFs) that quantified selection for elevation, termite mounds, and distance to floodwaters in the week before (purple) and after (yellow) Idai. Positive coefficients indicate selection and negative coefficients indicate avoidance; CIs not overlapping zero indicate significant selection or avoidance; CIs not overlapping each other indicate significant differences before vs. after landfall. Although bushbuck killed by Cyclone Idai significantly increased their selection for higher elevations and mounds (non-overlapping CIs for all coefficients before vs. after landfall), they were unable to avoid the flood edge (indicated by positive coefficients) and died in water >1.5-m deep.
