探索可塑性的因果成分对于洞察进化动力学和生物体应对气候变化的能力非常重要。在个体之间，可塑性的变化可能是由于基因型-环境相互作用（G X E）或与个体相关的环境影响的结果。我们调查可塑性的奠定日期在共同的海鸥Larus犬，在爱沙尼亚收集的数据在37年（n = 11 624记录2262女性，472亲属）。我们使用了滑动窗口的方法来找到在春季期间，平均温度最好地解释了年平均产卵日期。然后，考虑到春季温度作为环境的定量描述，我们使用系谱信息和随机回归动物模型来确定产蛋日期-温度关系的可塑性变化。我们发现，个体在产蛋日期的可塑性方面存在差异（例如，在温暖的春季，个体之间的产蛋日期变异增加），产蛋日期的变异约有11%是可遗传的，但我们没有发现G X E的统计支持。这个物种的可塑性不受温暖的春天的限制。
Exploration of causal components of plasticity is important for insight into evolutionary dynamics and an organism's ability to respond to climate change. Among individuals, variation in plasticity can be due to genotype-environment interaction (G X E) or a result from environmental effects associated with an individual. We investigated plasticity for laying date in the common gulls Larus canus, using data collected in Estonia during 37 years (n = 11 624 records on 2262 females, with 472 relatives). We used a sliding window approach to find the period in spring during which mean temperature best explained the annual mean laying date. Then, considering the spring temperature as a quantitative description of the environment, we used pedigree information and a random regression animal model to determine the variation in plasticity for the laying date - temperature relationship. We found that individuals differ in the plasticity of laying date (such that there is increased variation among individuals for the laying date in warmer springs), and that approximately 11% of variation in the laying date is heritable, but we found no statistical support for G X E. Plasticity in this species is not constrained by warmer springs.
