陆蛙的叫声活动可以用来衡量栖息地是否适合繁殖。我们评估了 12 个恢复年龄不同的次生林地点以及哥斯达黎加加勒比海地区的 3 个老生长点中常见的丁蛙 Diasporus diastema（Eleutherodactylidae）的叫声活动。我们沿横断面进行了视觉和听觉调查，在每个地点总共 12 小时的普查中仅识别出了 26 个人。我们还使用了记录中的自动物种识别，并在 49,273 个记录中的 10,605 个记录中检测到了 D. diastema。日通话活动高峰出现在2100点到0100点，月活动高峰出现在5月份。不同森林地点的叫声活动没有差异，这表明次生林可以为 D. diastema 繁殖提供合适的栖息地。
Calling activity in terrestrial frogs can be used as a measure of habitat suitability for reproduction. We evaluated the calling activity of the common tink frog Diasporus diastema (Eleutherodactylidae) in 12 secondary forest sites that vary in age of recovery, and three old growth sites in the Caribbean of Costa Rica. We used visual and acoustic surveys along transects, and we identified only 26 individuals in a total of 12 hours of censuses for each site. We also used automated species identification from recordings, and we detected D. diastema in 10,605 of 49,273 recordings. The peak of the daily calling activity occurred from 2100h to 0100h, and the peak of monthly activity occurred in May. Calling activity did not vary among the different forest sites, suggesting that secondary forests can provide suitable habitat for D. diastema reproduction.
