Dendrochronological advances in the tropical and subtropical Americas: Research priorities and future directions

Abstract

This Special Issue presents recent advancements in tropical dendrochronology in the tropical and subtropical Americas, focusing on the identification of new species for dendrochronological studies, the assessment of climate information contained in tree-ring records, and systematic reviews of past research. The studies included in this issue significantly contribute to our understanding of tree species suitable for dendrochronology and the improvement of dating techniques. Moreover, they delve into the relationships between climate variables and tree growth, offering insights into the response of tropical forests to environmental change and providing tools for reconstructing past climate conditions. These studies also shed light on the challenges associated with accurately distinguishing annual ring boundaries in tropical species with complex anatomical structures and emphasize the importance of integrating complementary dating methods and visualization techniques to enhance the reliability of dendrochronological studies in the tropics. By synthesizing diverse research findings, this Special Issue offers a comprehensive overview of tropical dendrochronology in the American (sub) tropics, revealing gaps in knowledge, and suggesting potential avenues for future research. Ultimately, these advancements promote a deeper understanding of tropical forests, their role in the global climate system, and the need for their sustainable management and conservation.
