Mating behavior of Hyla meridionalis was observed at an artificial reservoir in Punta del Hidalgo, Tenerife. Playback experiments were conducted in the field near the reservoir. The density of calling males was extremely high, and individuals sometimes called within 5 cm of each other. Males often changed calling positions and successfully attempted to clasp one another. Gravid females were common and most often found in amplexus. In three of four observations, the male initiated amplexus from a distance of 5 to 10 cm. Only 11 of 107 gravid females responded in two-choice playback experiments. Ten chose the calls of a conspecific male recorded at Punta del Hidalgo, and one female chose the calls of a male of H. a. arborea recorded in Germany. Our observations and experimental results are compared with those of similar studies of North American hylids.
在特内里费岛伊达尔戈角的一个人工水库观察了南方雨蛙的交配行为。在水库附近的野外进行了回放实验。鸣叫雄性的密度极高，个体之间有时相距不到5厘米就鸣叫。雄性经常变换鸣叫位置，并成功地试图相互抱合。怀孕的雌性很常见，最常出现在抱合状态。在四次观察中的三次中，雄性从5到10厘米的距离开始抱合。在双选回放实验中，107只怀孕雌性中只有11只做出了反应。10只选择了在伊达尔戈角录制的同种雄性的叫声，1只雌性选择了在德国录制的北美雨蛙雄性的叫声。我们将观察结果和实验结果与北美雨蛙类似研究的结果进行了比较。
