Abstract
Life history strategies are fundamental to the ecology and evolution of organisms and are 2 important for understanding extinction risk and responses to global change. Using global 3 datasets and a multiple response modelling framework we show that trait-climate interactions 4 are associated with life history strategies for a diverse range of plant species at the global scale. 5 Our modelling framework informs our understanding of trade-offs and positive correlations 6 between elements of life history after accounting for environmental context and evolutionary 7 and trait-based constraints. Interactions between plant traits and climatic context were needed 8 to explain variation in age at maturity, distribution of mortality across the lifespan, generation 9 time of species. Mean age at maturity and the distribution of mortality across plants’ lifespan 10 were under evolutionary constraints. These findings provide empirical support for the 11 theoretical expectation that climatic context is key to understanding trait to life history 12 relationships globally.
