Forecasts of community dynamics are essential for the management of biodiversity. Theory suggests these predictions can be improved by leveraging multi-species dependencies to improve models, but empirical support for this is lacking. We test whether models that learn from multiple species, both to estimate nonlinear environmental effects and temporal dependence, improve forecasts for a semi-arid [...]

1. Simulation models are valuable tools for estimating ecosystem structure and function under various climatic and environmental conditions and disturbance regimes, and are particularly relevant for investigating the potential impacts of climate change on ecosystems. However, because computational requirements can restrict the number of feasible simulations, they are often run at coarse scales or [...]
