Litterfall and nutrient transfer dynamics in a successional gradient of tropical dry forest in Colombia

Introduction: The litterfall production, foliar nutrient dynamics and decomposition are essential to maintain cycling, soil fertility, carbon regulation in terrestrial ecosystems. With several studies addressing the variation of these processes, their tropical dry forests (TDFs) remain unclear, due its complex interaction biotic abiotic factors. Objective: To evaluate litterfall, potential return use efficiency, a TDF successional gradient Tolima, Colombia. Methods: We quantified from November 2017 October 2019 12 plots distributed four stages: initial, early, intermediate, late forests. identified key tree species litter production characterized species. At community level, we C, N P return, C:N N:P ratio. Subsequently, analyze relationships between vegetation characteristics some chemical properties with ecological processes. Results: found that total (8.46 Mg ha-1 y-1) was double initial (4.45 y-1). Decomposition higher (k = 1.28) compared intermediate 0.97) 0.87). didn’t change along succession, but it did show differences study sites. structural development richness favored while conditions influenced returns decomposition. Conclusions: TDFs could recover ecosystem function related after disturbances cessation; however, quality is fundamental release nutrients.
