资源简介:

Based on daily monitoring around an urban pond in the coastal town of Maroantsetra, from 2003-2011, we provide an analysis of the yearly reproductive activity of the tomato frog (Dyscophus antongilii), a large-sized and prominent red-coloured microhylid frog from north-eastern Madagascar. Frogs were observed all year round but despite the lack of limited climatic seasonality in the region it was possible to observe a high activity period between January-May and a lower activity period between June-December. Freshly laid eggs were found in all months except November, and with highest incidence between January and May, while calling was heard in all months. We found a positive correlation between daily adult counts and minimum air temperature. On the contrary rainfall did not significantly predict activity, although boosts of calling and egg-laying especially in the austral winter were observed after heavy rainfall events. We define D. antongilii in Maroantsetra as a sporadic wet season breeder that reproduces at irregular intervals following heavy rain events.

本数据集基于2003年至2011年对沿海城镇马南扎里(Maroantsetra)一处城市池塘周边的日常监测,针对番茄蛙(Dyscophus antongilii)的年度繁殖活动展开分析。该物种为马达加斯加东北部特有的大型标志性红色姬蛙科蛙类。研究对象全年均有观测记录,尽管该区域气候季节性并不显著,仍可观测到1月至5月的活动高峰期与6月至12月的活动低谷期。研究人员在除11月外的所有月份均发现了新鲜产卵记录,且产卵高发期同样集中在1月至5月;而雄性鸣唱行为则在全年各月均有观测记录。本研究发现,每日成蛙计数与最低气温呈显著正相关。与之相反,降雨量并未显著预测蛙类活动水平,尽管在强降雨事件后,尤其是南半球冬季期间,观测到了鸣唱与产卵行为的显著激增。我们将马南扎里地区的D. antongilii定义为偶发性湿季繁殖类群,其会在强降雨事件后以不规则间隔开展繁殖活动。
