城市化对两栖动物群落、种群和个体产生了重大影响，因为栖息地丧失、栖息地质量下降和栖息地破碎化。无尾两栖类的广告叫声用于交流，在繁殖中起着重要的作用;然而，人为噪声和城市化引起的栖息地变化如何影响无尾两栖类的广告叫声却鲜为人知。在这项研究中，我们研究了两种青蛙的广告呼叫的变化，在繁殖季节期间，沿沿着城市-农村梯度在中国上海，中国的侏儒蛙（Microhyla fissipes）和水稻蛙（Fejervarya multistriata）。我们使用的不透水面积（包括建筑物和道路）在每2公里半径的景观的百分比，代表34个研究地点的城市化指数。然后，我们测量了这两个物种的五个广告呼叫参数（呼叫持续时间，呼叫间隔，呼叫率，脉搏率和主频）（100名男性的F。multistriata和M. fissipes）在每个研究中心的2020年和2021年5月至7月。我们探讨了城市化指数和其他变量（空气温度，口鼻长度和呼叫情况（一个青蛙物种呼叫，或两个青蛙物种一起呼叫））在每个研究地点如何影响这些呼叫参数。结果表明，M.裂足类与城市化指数呈显著负相关，鸣叫持续时间和鸣叫间隔与气温呈显著负相关，鸣叫频率和脉搏率与气温呈显著正相关，鸣叫持续时间与口鼻长呈显著正相关。对于F.脉冲频率与城市化指数、口鼻长度和环境（两种蛙在一起鸣叫）呈显著负相关，与气温呈显著正相关;而鸣叫间隔与口鼻长度呈显著正相关。这两种蛙对城市化的反应不同，有助于我们更好地理解快速城市化下无尾两栖类繁殖行为和繁殖生活史策略的变化。
Urbanization has a significant influence on amphibian communities, populations, and individuals because of habitat loss, degradation of habitat quality, and habitat fragmentation. Advertisement calls of anurans are used for communication and play an important role in reproduction; however, how anthropogenic noise and habitat change caused by urbanization affect anuran advertisement calls is less well known. In this study, we examined changes in the advertisement calls of two frog species, the ornamented pygmy frog (Microhyla fissipes) and rice frog (Fejervarya multistriata), during the breeding season along an urban–rural gradient in Shanghai, China. We used the percentage of impervious area (including buildings and roads) in each 2 km-radius landscape to represent the urbanization index of 34 study sites. We then measured five advertisement call parameters (call duration, call interval, call rate, pulse rate, and dominant frequency) of these two species (100 males of F. multistriata and 89 males of M. fissipes) in each study site from May to July in 2020 and 2021. We explored how the urbanization index and other variables (air temperature, snout–vent length and calling situation (one frog species calling, or two frog species calling together)) in each study site affected these call parameters. The results showed that the dominant frequency of M. fissipes was significantly negatively related to urbanization index, and call duration and call interval were significantly negatively related to air temperature; furthermore, call rate and pulse rate were significantly positively related to air temperature, and call duration was also significantly positively related to snout–vent length. For F. multistriata, pulse rate was significantly negatively related to urbanization index, snout–vent length, and situation (two frog species calling together), but significantly positively related to air temperature; by contrast, call interval was significantly positively related to snout–vent length. We suggested that these two frog species had different responses to urbanization, which could help us to better understand the change of anuran breeding behaviors and reproductive life-history strategies in the face of rapid urbanization.
