Abstract
Tropical cyclones (i.e., hurricanes, typhoons) cause large pulse fluxes of leaves that have not undergone senescence (i.e., green litter) to forest soils, with consequences for biogeochemical cycling. Energy and mineral nutrient concentrations of green litter are higher than the naturally senesced litter, likely affecting rates of decomposition and nutrient release, as well as the structure and composition of detrital food webs, but these effects have not been well quantified.
During the typhoon ‘Hagubit’, we collected green and senesced litter from three common urban greening species, and then conducted a 316 days field experiment to evaluate substrate quality affected the trophic multifunctionality of soil faunal communities, and ultimately elemental release from the decomposing litter.
Nitrogen (N), phosphorus (P), potassium (K), sodium (Na), calcium (Ca), and magnesium (Mg) were released at significantly higher rates from green litter than senesced litter. Aluminum (Al), manganese (Mn), and iron (Fe) displayed a net accumulation during litter decomposition, and the immobilization of these elements was significantly higher in green than senesced litter. Litter substrate chemistry directly affected the release rates of elements, but its influence was stronger in decomposing senesced litter compared to green litter. Detritivores dominated green and senesced litter faunal communities relative to predators, omnivores, and herbivores, and these distinct fauna functional groups showed significantly positive correlation during decomposition, but soil fauna trophic multifunctionality was significantly higher in green litter and stimulated the release of elements.
These findings suggest that typhoons dramatically alter the dynamics of nutrient release during litter decomposition, and the influences are mediated in part by its substrate quality and changes in soil fauna trophic multifunctionality, which has significant implications for the magnitude and timing of soil nutrient availability after typhoon disturbances.

Description of the data and file structure
- This dataset has one EXCEL. xlsx file with two parts (1: Nutrientelements, 2: Soilfauna) in the article, specifically as follow:
- For the data of Nutrientelements, the variations includes litter mass, N, P, K, Na, Ca, Mg, Al, Mn, and Fe. The microsite have three as replicate. the sampling includes the initial substrate data and the subsequent the days of 92, 182, 250, 281, and 316. For the "senesced litter-K. bipinnata_0.04*3mm" is the decomposition of the senesced litter of K. bipinnata in litterbags with mesh size of 0.04*3mm, and each other column is encoded the same way.
- For the data of soilfauna, sampling1, 2, 3, and 4 is the decomposition after the days of 92, 182, 250, 281. For the "senesced litter-K. bipinnata-microsite1" is the soil fanua from the decomposing senesced litter of K. bipinnata in the microsite1, and each other column is encoded the same way. It's noted that the taxonomy of predators, herbivores, omnivores, and detritivores based on the distinct feeding preferences and which was detailed described in the section of METHOD and the online supporting information.
Methods
This dataset regarding litter N, P, K, Na, Ca, Mg, Al, Mn, and Fe as well as soil fauna with distinct feeding preferences, which were collected from litter decomposition experiment and all detailed information can be found in the section of METHODS.
