In Focus: Radchuk, V., Turlure, C. & Schtickzelle, N. (2013) Each life stage matters: the importance of assessing response to climate change over the complete life cycle in butterflies. Journal of Animal Ecology, 82, 275-285. Population-level responses to climate change depend on many factors, including unexpected interactions among life history attributes; however, few studies examine climate change impacts over complete life cycles of focal species. Radchuk, Turlure & Schtickzelle () used experimental and modelling approaches to predict population dynamics for the bog fritillary butterfly under warming scenarios. Although they found that warming improved fertility and survival of all stages with one exception, populations were predicted to decline because overwintering larvae, whose survival declined with warming, were disproportionately important contributors to population growth. This underscores the importance of considering all life history stages in analyses of climate change's effects on population dynamics.
Radchuk、Turlure 和 Schtickzelle（2013 年）每个生命阶段都很重要：在蝴蝶中评估对气候变化的反应在完整生命周期中的重要性。动物生态学杂志，82，275-285. 对气候变化的种群反应取决于许多因素，包括生活史属性之间意想不到的相互作用；然而，很少有研究在焦点物种的完整生命周期中研究气候变化的影响。Radchuk、Turlure 和 Schtickzelle（）使用实验和建模方法来预测在变暖情景下沼泽地蝴蝶的种群动态。尽管他们发现变暖改善了所有阶段的生育力和存活率，但除了一个例外，由于越冬幼虫的存活率随变暖而下降，对种群增长的贡献不成比例地重要，因此预计种群会减少。这强调了在分析气候变化对种群动态的影响时考虑所有生活史阶段的重要性。
