A comparison of the differences in detection distances (average ± SD) of echolocation passes (n = 21 acoustic flight paths) when using different frequencies and SLs from the desert and fynbos biomes.

Detection distances were calculated using atmospheric conditions of flight paths recorded in the desert at Wondergat cave with a) average desert frequency with either average SL from the desert and fynbos biome b) average desert SL with average frequency from the desert and fynbos biome c) the average frequency and SL for each biome.
