Logging disturbance shifts net primary productivity and its allocation in Bornean tropical forests
The first measures of total net primary productivity and its allocation along a disturbance gradient from old-growth forests to moderately and heavily logged forests in Malaysian Borneo demonstrate that logging can cause substantial shifts in carbon production and allocation in tropical forests.
