Fig. 4. Crawling time. Data are only from trials in which we scored the detection
to have occurred `from crawling'. Bars represent means ± s.e.m. of
individual medians (N=11 bats). Tasks are abbreviated as follows: E,
echolocation; VE, vision + echolocation; TE, temperature + echolocation; AE,
acoustic cues + echolocation; OE, olfaction + echolocation. Significant
results from post-hoc comparisons of bats' performance in the
echolocation task (grey bar) compared with the other four tasks are indicated
in the graph [paired t-tests, Bonferroni corrected P-values:
(*), significance lost when Bonferroni correction was applied;
uncorrected P<0.05]. For further statistics, see text.
