Spatial Distribution of Carbon Stored in Forests of the Democratic Republic of Congo.

National forest inventories in tropical regions are sparse and have large uncertainty in capturing the physiographical variations of forest carbon across landscapes. Here, we produce for the first time the spatial patterns of carbon stored in forests of Democratic Republic of Congo (DRC) by using airborne LiDAR inventory of more than 432,000 ha of forests based on a designed probability sampling methodology. The LiDAR mean top canopy height measurements were trained to develop an unbiased carbon estimator by using 92 1-ha ground plots distributed across key forest types in DRC.

Effects of exercise training on calf tissue oxygenation in men with intermittent claudication.

Objective: To determine the effects of exercise training on calf tissue oxygenation in men with peripheral arterial disease and intermittent calf claudication.

Design: This pilot study was prospective and longitudinal and used a one-group, pretest-posttest design.

Setting: Tertiary care medical center for veterans.
