Tumultivenia and Uniostium, two new genera of Anacardiaceae-Spondioideae, are described and illustrated, as is one new species, Cyrtocarpa caribaea.

Pervasive gaps in Amazonian ecological research

We integrate ecological community metadata of 7,694 sampling sites for multiple organism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change.
