摘　　要：城市化是造成全球两栖类多样性下降的重要原因,两栖类通过表型特征(尤其是形态特征)的改变响应城市化进程。于2020—2021年4—8月沿上海市城市化梯度设置38个研究样点,共采集170只金线侧褶蛙和305只泽陆蛙成体,以获取5项形态特征数据(体长、体重、头宽、前臂长和后肢长),基于各样点的建筑、道路和林地面积占比定义城市化指数以代表城市化水平,分析上海市城市化对金线侧褶蛙和泽陆蛙形态特征的影响。结果表明:雄性与雌性金线侧褶蛙的体长与城市化指数呈显著正相关,雄性泽陆蛙的体长、头宽和后肢长,以及雌性泽陆蛙的体重和后肢长与城市化指数呈显著正相关。本研究表明,泽陆蛙对上海市城市化进程的形态特征响应强于金线侧褶蛙。Urbanization leads to globally decline of amphibian biodiversity.Amphibians change their phenotypic characteristics,especially morphological traits,to adapt to urbanization.To examine the effects of urbanization on the morphological traits of the gold-striped pond frog(Pelophylax plancyi)and rice-paddy frog(Fejervarya multistriata)in Shanghai,China,we collected 170 individuals of adult P.plancyi and 305 individuals of adult F.multistriata from 38 sampling sites along an urbanization gradient between April and August in 2020 and 2021.We measured five morphological traits:snout-vent length,body mass,head width,forelimb length,and hindlimb length.The urbanization index of each sampling site was evaluated based on the area proportions of buildings,roads,and woodlands,to represent the urbanization level.The snout-vent length in both male and female P.plancyi was positively correlated with the urbanization index.The snout-vent length,head width,and hindlimb length in male F.multistriata,and body mass and hindlimb length in female F.multistriata were positively correlated with the urbanization index.Our results indicate that the responses of the morphological traits to urbanization were stronger in F.multistriata than P.plancyi in Shanghai.
