During the summer months each year, when US-NGC is accessible by road, blueberries fruit across the surrounding tundra and river valleys, attracting… More

The inhibition of leaf respiration in the light has long been reported at a leaf scale, but recent isotopic evidence suggests that inhibition also occurs at the ecosystem scale. This is important, as inhibition at the ecosystem scale would imply a significant bias in current estimates of ecosystem photosynthesis and respiration, but it is not known… More
