Query: Trait-based population dynamics shape the contours of fitness landscapes Ecological responses to environmental change are driven by population demography1,2, yet trait-based population dynamics are rarely used to project community assemblages3. Fitness landscapes describe how selection influences the evolution of species4,5 and can be extended to multispecies communities along environmental gradients based on the matching of traits to local environmental conditions6. Knowing the contours of fitness landscapes would improve our understanding of how selection shapes ecological communities and would permit predictions of community dynamics in changing environments. However, the shape of fitness landscapes for multispecies communities is unknown because we have lacked a framework for estimating fitness across individuals, phenotypes, and environments. Here we describe a new framework to estimate multispecies fitness landscapes and illustrate model results for trees in temperate forests across a climatic gradient in the eastern United States. Demographic models showed that multivariate phenotypes interact with climate to influence rates of tree growth, survival, and reproduction and generate demographic trade-offs that constrain life history strategies. By integrating trait effects on demographic performance across the life cycle, we estimated the net effect of traits on fitness and reveal the shapes of fitness landscapes driven by temperature. With increasing availability of trait7 and demographic data8,9, our approach can be applied to any ecological system, providing a pathway to generate mechanistic, general predictions of population and community responses to environmental change.
