The Caatinga is an ecologically unique semi-arid region of northeast Brazil characterized by high levels of endemism and severe anthropogenic threats from agricultural development and climate change. It is also one of the least known biomes in Brazil due to a combination of inadequate investment, low regional research capacity and difficult working conditions. However, while the lack of scientific knowledge of the Caatinga is well known, the spatial and temporal distribution of knowledge production has not been investigated.

- The Amazon rainforest is facing longer and more intense dry seasons, impacting tree species that might adapt through changes in leaf morphology.
- Historical analysis of herbarium specimens for six tree species over 60 years showed a trend of decreasing leaf size linked to reduced rainfall.
- Although the findings suggest some Amazonian trees can adapt to climate changes, biases in specimen collection mean caution is needed when applying these results to all tree species in the region.
