Table dos. For men, level of tunes analysed is provided once the final amount and also the selection of tunes analysed each individual into the mounts. For men, amount of nest sites equal what amount of men submitted, for females, they stands for how many nests where we seen them. Male sound properties was basically averaged on private level just before calculating the newest presented analysis. Indicate ± SD | Median is given into level of pulses for each voice, cycle, pulse rate and principal frequency

Figure step 3. Multiple pulse sounds developed by the corkwing wrasse. Wave-form (top) and related spectrogram (below). (a) Grunt regarding a good territorial male corkwing wrasse. (b) Deep grunt away from a great territorial men corkwing wrasse. (c) Grunt out of a woman corkwing wrasse. Spectrogram options: fifty dB vibrant assortment, Hamming screen (raised sine-squared), 0.008 s window duration (female and male grunt), 0.08 s window duration (men strong grunt)

Profile 3. Multiple pulse songs produced by new corkwing wrasse. Wave form (top) and corresponding spectrogram (below). (a) Grunt from good territorial men corkwing wrasse. (b) Deep grunt out-of a great territorial male corkwing wrasse. (c) Grunt off a woman corkwing wrasse. Spectrogram setup: fifty dB vibrant variety, Hamming windows (raised sine-squared), 0.008 s windows size (male and female grunt), 0.08 s window length (men deep grunt)

Because of the different structure of grunts and deep grunts, we only compared the sound properties statistically, which were the same in both types of grunt, i.e. dominant frequency and duration. The two male grunt types differ significantly from each other in both propertiespared to deep grunts, male grunts are of a shorter duration (t-test: t = 5.44, P < 0.00step 1, CI = ?0.47–1.09). The dominant frequency is higher in male grunts than in male deep grunts (Mann Whitney U test: W = 0, N1 = 17, N2 = 11, P < 0.001). Table 2 presents all measured sound properties for comparison.

Compared to male grunts, female grunts had a significantly lower pulse-rate (t-test: t = -6.71, P < 0.0001, CI = — -). Grunts of males and females had a similar dominant frequency (t-test: t = 1.38, P = 0.17, CI = -0.05- 0.26), duration (t-test: t = 0.47, P = 0.64, CI = -0.19- 0.26), and number of pulses (Mann Whitney U test: W = 302, N1 = 17, N2 = 35, P = 0.94).

Single-heart circulation sounds

Your choice of demonstrably assignable presses contributed to the research away from 102 men ticks off 29 videos off 19 somebody and you will 66 ladies ticks away from 20 movies at nests regarding fourteen guys. The selection of obviously assignable plops triggered the analysis of 73 men plops regarding twenty-eight clips out-of 18 videos and 66 lady plops from 21 video clips within nests off fourteen men. Averaging male musical for each and every personal male lead to an example measurements of letter = 18 to own clicks, and you can n = 17 to have plops.

Clicks are sharp, single-pulse broadband sounds with their main energy in a frequency range of several hundred Hz, while the sound pressure level difference across the harmonics are small (Figure 4(a), Table 3). The dominant frequency of clicks was significantly higher in males than in females (Mann Whitney U test: W = 409, N1 = 35, N2 = 66, P = 0.04). However, there were some female clicks for which the dominant frequency was much higher than in most clicks (up to 7200 Hz). We did not see any technical reason to exclude these outliers from the analysis. Clicks did not differ between males and females in the sound pressure level difference between dominant frequency and its 5 th harmonic (t-test: t48.4 = 0.84, P = 0.40, CI = ?2.17–5.31).
