Forest productivity mitigates human disturbance effects on late-seral prey exposed to apparent competitors and predators

Abstract Primary production can determine the outcome of management actions on ecosystem properties, thereby defining sustainable management. Yet human agencies commonly overlook spatio-temporal variations in productivity by recommending fixed resource extraction thresholds. We studied the influence...
