Life history strategies are fundamental to the ecology and evolution of organisms and are important for understanding extinction risk and responses to global change. Using global datasets and a multiple response modelling framework we show that trait‐climate interactions are associated with life history strategies for a diverse range of plant species at the global scale. Our modelling framework informs our understanding of trade‐offs and positive correlations between elements of life history after accounting for environmental context and evolutionary and trait‐based constraints. Interactions between plant traits and climatic context were needed to explain variation in age at maturity, distribution of mortality across the lifespan and generation times of species. Mean age at maturity and the distribution of mortality across plants’ lifespan were under evolutionary constraints. These findings provide empirical support for the theoretical expectation that climatic context is key to understanding trait to life history relationships globally.

需要气候和进化背景，才能从全球范围内的功能性状中推断出植物生命史的策略

生命史策略对有机体的生态和进化至关重要，对于理解灭绝风险和对全球变化的响应也很重要。使用全球数据集和多重响应建模框架，我们表明，性状-气候相互作用与全球范围内各种植物物种的生命史策略相关。我们的建模框架在考虑了环境背景以及基于进化和特征的约束条件后，帮助我们了解了权衡和生活史要素之间的正相关关系。需要植物性状和气候环境之间的相互作用来解释成熟期的年龄变化，整个寿命的死亡率分布和物种的产生时间。成熟期的平均年龄和整个植物寿命的死亡率分布受到进化的限制。这些发现为理论上的期望提供了经验支持，因为气候背景是理解全球生命史关系特征的关键。
