The paper investigates gene flow and species boundaries in Andean Prunus, finding extensive ancient introgression and recent admixture despite Miocene divergence.

This paper develops a scalable method to prioritize areas for plant occurrence data collection, validated by experts and adaptable to national priorities.

This study uses ecological metabolomics to show that chemical dissimilarity among tree species increases with species richness and warm, wet climates, supporting the role of chemically mediated biotic interactions in shaping elevational diversity gradients.
