Phenological shifts vary within and among insect species and locations based on exposure and sensitivity to climate change. Shifts in environmental conditions and seasonal constraints along elevation and latitudinal gradients can select for differences in temperature sensitivity that generate differential phenological shifts. I examine the phenological implications of observed variation in developmental traits. Coupling physiological and ecological insight to link the environmental sensitivity of development to phenology and fitness offers promise in understanding variable phenological responses to climate change and their community and ecosystem implications. A key challenge in establishing these linkages is extrapolating controlled, laboratory experiments to temporally variable, natural environments. New lab and field experiments that incorporate realistic environmental variation are needed to test the extrapolations. Establishing the linkages can aid understanding and anticipating impacts of climate change on insects.
物候变化在不同昆虫物种和地点之间存在差异，这取决于它们对气候变化的暴露程度和敏感度。在海拔和纬度梯度上，环境条件和季节性限制的变化可以选择对温度敏感度的差异，从而产生不同的物候变化。我研究了观察到的发育特征变化对物候的影响。将生理学和生态学的见解结合起来，将发育对环境的敏感性与物候和适应性联系起来，有望理解气候变化对物候的可变影响及其对群落和生态系统的影响。建立这些联系的一个关键挑战是将受控的实验室实验外推到时间变化的自然环境中。需要新的实验室和野外实验来整合现实的环境变化，以检验这些外推。建立联系可以帮助我们理解和预测气候变化对昆虫的影响。
