Data to "Prioritizing spatial extent over resolution in shaping the performance of species distribution models: Insights from a multi-scale assessment of Cerris oaks in China"

We demonstrate that spatial extent has a stronger influence on model accuracy than resolution, with national-scale models performing better than narrower climatic extent ones. Our findings highlight the need to prioritize appropriate spatial extent and carefully consider resolution in relation to species-specific traits when designing SDMs.

This work offers a transferable approach for building robust, ecologically realistic SDMs under multi-scale environmental conditions, which is crucial for biodiversity conservation and ecological forecasting.
