It has been shown that trees get older in the wet tropics, but the mechanisms behind this observation are still not clear. Literature shows that moisture could directly affect longevity by modulating physiological processes of trees. Other studies point to the potential role of water on tree size, which could indirectly affect longevity if one reconciles to the fact that the growth rate of tropical trees doesn’t differ significantly between wet and dry sites. The third group points to the ...
Water scarcity is a major 21st century challenge that is increasing the vulnerability of the human population, especially in cities. Water risk assessment is a fundamental task in many cities worldwide that often lack long-term and spatially-resolved records of precipitation and level of water reservoirs. Past rainfall and reservoirs levels may be alternatively assessed using tree-ring stable isotopes of urban trees. We assessed the past variability of precipitation and reservoirs level th...

How old are tropical trees? This fundamental question has long driven the curiosity of laymen and scientists. But only recently, a great number of studies conducted by many brave dendrochronologists resulted in a significant tree-ring-based knowledge that allows us to start accurately estimating tree ages across the globe. As science goes, not only knowing the longevity of tropical trees is essential to understanding forest dynamics and its role in biogeochemical cycles, but one must also ...
Dendrochronological archives in the tropics of the Americas have been under-studied for a long time. Some of the challenges include the Identification of tree-ring boundaries in certain tree species, absence of winter dormancy associated to low temperatures in most of the cases, and logistic difficulties of fieldwork in remote sites. However, part of the slow progress is also related to the fact that historically much less resources have been inv...
