For species with environmental sex determination, understanding the relationship between reproduction and environmental factors is important for predicting their reproductive output. Here, we study intra-annual variation in green turtle nesting during the 2010–2016 seasons at Penang Island (5°16′28″–5°28′15″N 100°10′52″–100°11′55″E), Malaysia. The additive modelling on a monthly-basis number of nests shows that fluctuation in the number of nests relates to temperature in addition to month of year, rather than precipitation. The number of nests tended to be higher in response to higher temperature during March–July, whereas the lower temperature during August–February also tended to result in a relatively higher number of nests. Concentration of nests during March–July resulted from a shorter inter-nesting interval during warm temperatures, whereas relatively low temperatures may homogenize the temporal distribution of the number of nests. This study provides fundamental information for green turtle nesting seasonality in response to environmental change.

马来西亚槟城岛绿海龟 (Chelonia mydas) 的生殖季节性和环境影响

对于具有环境性别决定的物种，了解繁殖与环境因素之间的关系对于预测其繁殖产量很重要。在这里，我们研究了 2010-2016 季节在槟城岛 (5°16′28″–5°28′15″N 100°10′52″–100°11′55″E) 绿海龟筑巢的年内变化), 马来西亚。以月为基础的巢穴数量的加性模型表明，巢穴数量的波动与温度和一年中的月份有关，而不是与降水有关。3-7 月温度较高，巢数趋于增加，而 8-2 月温度较低，巢数也相对较多。3 月至 7 月期间巢穴集中是由于在温暖的温度下筑巢间隔较短，而相对较低的温度可能会使巢数的时间分布均匀化。本研究为响应环境变化的绿海龟筑巢季节性提供了基本信息。
