Leaf Litter Decomposition in the Tropics Dynamically Recovers Following Experimental Disturbance Across Temporal Scales

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
Litter decomposition by arthropods and microbes is a key ecosystem process in tropical forests, yet its response to disturbance and forest regeneration remains poorly understood. To investigate decomposition dynamics across forest succession, we conducted a space‐for‐time study in the Ecuadorian lowland Chocó spanning active cacao plantations and ...
