Water availability changes carbon and nutrient dynamics along a natural precipitation gradient

I evaluated effects of increasing water availability on carbon and nutrient cycling across a broad precipitation gradient in native-dominated forests in Hawai'i. I measured soil and foliar nutrients, aboveground net primary production (ANPP), and litter decomposition and nutrient release in five sites ranging in mean annual precipitation from 500 mm to 5500 mm on the island of Hawai'i. All sites were on 'a'a lava flows of similar age, (...
