Estratégias ecológicas associadas aos padrões de sazonalidade da fenologia foliar na Amazônia Central

Research in the Central Amazon Conservation Complex reveals that variations in leaf phenology can serve as early warning signals for tree mortality, occurring up to seven and a half years before death. This finding suggests that tree death is not solely driven by external disturbances but also involves internal physiological decline and aging. The study analyzed 52 years of phenological data from hundreds of trees, demonstrating that water table depth significantly influences leaf production patterns, duration, and timing. Additionally, it identified two distinct phenological strategies in evergreen trees: one focused on drought avoidance/resource acquisition during wet periods, and another on drought resistance/resource conservation during drier periods. These insights enhance the understanding of Amazonian forest functionality and resilience, providing a systemic approach to predicting tree death and improving ecological models.
