在过去的20年里，温带地区的春季气温有所上升，许多生物体通过提前生长和繁殖的时间来应对这种上升。然而，并不是所有的种群都表现出物候学的进步。了解为什么有些种群会进化而有些则不会，将使我们深入了解物候学发展的可能限制和选择压力。通过结合20年来对24个山雀种群（Parus sp.）从六个欧洲国家，我们表明，在春季温度的大规模变化的物候反应不同的物种的范围，即使是位于彼此接近的人群。我们发现，这种变化不能完全解释的温度变化的变化，在前和后铺设期间，最近建议。相反，我们发现了温度升高和第二窝频率之间存在联系的证据，这导致了第一窝的产卵日期的复杂变化。我们的研究结果强调，需要考虑不同的生活史参数之间的联系，以预测大规模气候变化的生态后果。
Spring temperatures in temperate regions have increased over the past 20 years and many organisms have responded to this increase by advancing the timing of their growth and reproduction. However, not all populations show an advancement of phenology. Understanding why some populations advance and others do not will give us insight into the possible constraints and selection pressures on the advancement of phenology. By combining two decades of data on 24 populations of tits (Parus sp.) from six European countries, we show that the phenological response to large–scale changes in spring temperature varies across a species' range, even between populations situated close to each other. We show that this variation cannot be fully explained by variation in the temperature change during the pre– and post–laying periods, as recently suggested. Instead, we find evidence for a link between rising temperatures and the frequency of second broods, which results in complex shifts in the laying dates of first clutches. Our results emphasize the need to consider links between different life–history parameters in order to predict the ecological consequences of large–scale climate changes.
