This paper develops a framework to optimize plant species mixes for ecological restoration by prioritizing species based on functional attributes that support trophic relationships and ecosystem services.

The paper examines how Quaternary climate change influences tree beta-diversity globally, finding temperature changes since the Last Glacial Maximum strongly affect turnover and nestedness components.

The paper maps global tree diversity patterns and shows that both current and ancient climates influence tree species richness, functional, and phylogenetic diversity.

The paper creates the Global Root Trait (GRooT) Database to integrate root trait data into large-scale analyses by standardizing and curating root trait records from diverse studies.

The paper identifies priority areas for global tree conservation and finds that half are unprotected and face human threats.

The paper identifies factors driving mutualism breakdown between plants and arbuscular mycorrhizal fungi, finding that mutualism breakdown is stable only when plants switch to other symbionts or develop alternative resource acquisition strategies.
