Abstract

Forest Ecology Mosses can withstand long periods of desiccation, rehydrating with renewed precipitation. Hydrated mosses also accumulate substantial concentrations of nutrients in their tissues, which can be lost to their surroundings during desiccation and rehydration events. Slate et al. asked how these losses influence carbon and nitrogen cycling in soils in temperate forests. They found that throughfall of nutrients from rehydrated mosses, although variable between moss species, was often an order of magnitude greater than that from hydrated mosses. A single nutrient pulse from rehydration could be equivalent to a year's throughfall from the tree canopy. These findings suggest an important influence of mosses on forest soil carbon and nitrogen pools and on ecosystem responses to drought. J. Ecol. 10.1111/1365-2745.13162 (2019).
