{"data":[{"source":"bio.acousti.ca","id":"57574","topic":"behaviour","value":"Male Pithecopus rusticus vocalized from October\u2013 January, 19:00\u201300:00 at temperatures from 16.1\u201319.4\u00b0C. Males emitted three types of calls: one advertisement call and two territorial calls, referred to as territorial call I and territorial call II. The advertisement call (Fig. 2, Table 1) consisted of a short note with a duration of 0.023 \u00b1 0.002 ms (0.019\u20130.033 ms, n = 244), two pulses, and a dominant frequency of 2,311.028 \u00b1 159.155 Hz (1,924.500\u20132,830.200 Hz, n = 244).\n\nTerritorial call I (Fig. 3, Table 1) was emitted dur- ing male interactions. Its duration was 0.095 \u00b1 0.043 ms\n\n(0.033\u20130.166 ms, n = 27) and dominant frequency was 2,264.904 \u00b1 92.101 Hz (2,037.700\u20132,388.600 Hz, n = 27). This call consisted of two notes. The first note was 0.022 \u00b1 0.005 ms (0.016\u20130.039 ms, n = 27) long and was composed of two pulses. The second note was 0.008 \u00b1 0.002 ms (0.004\u20130.013 ms, n = 27) long and was composed of a single pulse. On four occasions, we ob- served the males interspersing advertisement calls with territorial call I.\n\nTerritorial call II (Fig. 4, Table 1) was emitted after territorial call I during interactions between male posi- tioned ca. 20 cm apart. Its duration was 0.911 \u00b1 0.340 ms (0.504\u20131.346 ms, n = 9) and dominant frequency was 2,122.867 \u00b1 139.496 Hz (1,924.500\u20132,274.900 Hz, n = 9). Territorial call II consisted of a single, multipulsed note.\n\nThe 12 recorded males measured 35.33\u201338.44 mm and weighed 3.0\u20134.6 g. Air temperature affected the duration of the advertisement call, with males decreas- ing advertisement call duration at higher temperatures (R2 = 0.53, p = 0.01; Fig. 5). There was no influence of SVL (R2 = 0.11, p = 0.28) or weight (R2 = 0.00, p = 0.86) on the dominant frequency of the advertisement calls.","topic_link":"http:\/\/rs.tdwg.org\/ontology\/voc\/SPMInfoItems#Behaviour","info_url":"https:\/\/bio.acousti.ca\/node\/57574"}]}
