Fig. 2From: Sexual dimorphism in echolocation pulse parameters of the CF-FM bat, Hipposideros pratti Sexual dimorphism of the CF, FM bandwidth, and PRR of echolocation pulses emitted by hanging Hipposideros pratti. A-1, B-1, C-1 vs. A-2, B-2, C-2: the distribution of CF, FM bandwidth, and PRR of echolocation pulses recorded from male and female bats. A-3, B-3, C-3: statistical comparison of these three pulse parameters recorded from male and female bats. The number within each parenthesis indicates the sample size. Student’s t test: *p < 0.05; **p < 0.01Back to article page
