This study compares pollinator communities in coffee agroforestry, monoculture, and tropical rainforest in DR Congo, finding agroforestry less effective than rainforest for pollinator conservation.

This study examines leaf trait variation and its climatic drivers in African Coffea species using phylogenetic comparative methods.

The paper examines hybridisation between cultivated Robusta coffee and its wild relative Coffea canephora in DR Congo, finding limited but detectable gene flow from cultivated to wild populations.

The paper assesses genetic diversity in wild and cultivated Coffea canephora in DR Congo, finding strong genetic differentiation between wild and cultivated populations and highlighting the need to enrich the INERA Yangambi Coffee Collection with local wild genotypes.
