Desk 2. For males, amount of musical analysed is given once the final number and the variety of audio analysed for every individual in mounts. For males, quantity of colony web sites equal the amount of males submitted, for females, it represents the amount of nests of which i noticed him or her. Male voice attributes was averaged towards the individual level in advance of figuring the brand new exhibited studies. Indicate ± SD | Median is provided with on quantity of pulses for every single voice, stage, heartbeat and you will principal volume

Shape 3. Multiple heart circulation songs angelreturn developed by this new corkwing wrasse. Wave form (top) and you will relevant spectrogram (below). (a) Grunt regarding an excellent territorial male corkwing wrasse. (b) Strong grunt out-of a great territorial male corkwing wrasse. (c) Grunt out-of a woman corkwing wrasse. Spectrogram options: fifty dB dynamic variety, Hamming windows (raised sine-squared), 0.008 s windows size (male and female grunt), 0.08 s windows length (men strong grunt)

Profile step three. Multiple heartbeat audio developed by the corkwing wrasse. Wave-form (top) and you can involved spectrogram (below). (a) Grunt from a good territorial male corkwing wrasse. (b) Strong grunt off a beneficial territorial male corkwing wrasse. (c) Grunt away from a lady corkwing wrasse. Spectrogram setup: 50 dB active diversity, Hamming windows (raised sine-squared), 0.008 s screen length (men and women grunt), 0.08 s windows duration (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 step 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 music

Your selection of clearly assignable presses triggered the analysis out of 102 male clicks out of 30 video clips off 19 someone and you can 66 female presses away from 20 movies within nests from fourteen males. The selection of certainly assignable plops resulted in the study of 73 male plops of 28 clips out-of 18 movies and you will 66 people plops off 21 video clips within nests out-of fourteen guys. Averaging male musical for every single personal men resulted in a sample measurements of letter = 18 to possess presses, and you will letter = 17 to possess 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: tforty eight.4 = 0.84, P = 0.40, CI = ?2.17–5.31).
