TITLE:

Response and recovery of radial growth of Dacryodes microcarpa (Burseraceae) and Ocotea guianensis (Lauraceae) to drought events in the Amazon-Cerrado transition

SUMMARY:

Tropical forests are important centers of biodiversity and carbon. However, climatic events such as extreme droughts have caused high mortality rates of trees in these ecosystems. The increased frequency and intensity of these droughts over the last few decades highlights the need to understand how trees in tropical forests respond to these events. In this context, this study aims to evaluate, through dendrochronological methods, the recovery, resistance, and resilience of radial growth of trees to drought events in a forest in the Amazon-Cerrado transition. We collected in a seasonally dry forest in the Mato Grosso state. For this, we obtained radial samples of the species Dacryodes microcarpa and Ocotea guianensis at the edge and interior forest using a presser probe and cross-sections of the stems. On these samples, we are applying standard dendrochronological methods, and the results will be validated through software and radiocarbon analysis. Our partial results demonstrate that the evaluated species have the potential for dendrochronological studies, being able to clearly capture the responses of resilience and recovery after drought events.
