Litter Dynamics and Nutrient Stocks in a Chronosequence of Hyperxerophilous Forest Under the Effect of Clear Felling

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We investigated litter accumulation and nutrient stocks across a forest regeneration chronosequence in hyperxerophilous Caatinga following clear‐cutting. Using multivariate statistics and structural decomposition indices, we identified functional litter profiles and their association with nutrient cycling and soil resilience. Our findings highlight how
