Impacts of Degradation on Water, Energy, and Carbon Cycling of the Amazon Tropical Forests

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 125, Issue 8, August 2020., 2020
Abstract Selective logging, fragmentation, and understory fires directly degrade forest structure and composition. However, studies addressing the effects of forest degradation on carbon, water, and energy cycles are scarce. Here, we integrate field observations and high‐resolution remote sensing from airborne lidar to provide realistic initial ...
