Therefore, the effects of tree species richness and  composition on the diversity of molecular components of SOC need to be  explored. In this study, we collected data on tree species diversity and  composition, SOC concentration, chemical composition, litter and fine root  properties, and examined the relationships between the richness,  composition and functional diversity of tree species, and the evenness of  SOC chemical compositions at a molecular level by 13C nuclear magnetic  resonance, across six natural forest types encompassing a diversity  gradient, ranging from cold temperate to tropical forests. Across the  range, tree species richness correlated to the evenness of SOC chemical  components through tree species composition. The negative correlation of  evenness of SOC chemical components with tree species composition and the  positive correlation of evenness of SOC chemical components with tree  functional diversity were found. The positive correlation of the evenness  of SOC chemical components with indicator tree species. These findings  suggest that the indicator tree species conservation might be preferable  to simply increasing tree species richness, for enhancing the potential  resistance of SOC to decomposition.", "keywords": ["leaf litter", "carbon (C)", "FOS: Agriculture", " forestry", " and fisheries", "14.

Grassland soils remain important reservoirs of carbon (C) and  nitrogen (N). Herbivores may affect both C and N pools and these changes  likely interact with increases in soil nutrient availability. Given the  scale of grassland soil fluxes, such changes can have striking  consequences for atmospheric C concentrations and the  climate.\u00a0Here, we use the Nutrient Network experiment to examine  the responses of soil C and N pools to mammalian herbivore exclusion  across 22 grasslands, under ambient and elevated nutrient availabilities  (fertilized with NPK + micronutrients). We show that the impact of  herbivore exclusion on soil C and N pools depends on  fertilization.\u00a0Under ambient nutrient conditions, we observed no  effect of herbivore exclusion, but under elevated nutrient supply, pools  are smaller upon herbivore exclusion. The highest mean soil C and N pools  were found in grazed and fertilized plots. The decrease in soil C and N  upon herbivore exclusion in combination with fertilization correlated with  a decrease in aboveground plant biomass and microbial activity, indicating  a reduced storage of organic matter and microbial residues as soil C and  N. The response of soil C and N pools to herbivore exclusion was  contingent on temperature \u2013 herbivores likely cause losses of C and N in  colder sites and increases in warmer sites. Additionally, grasslands that  contain mammalian herbivores have the potential to sequester more N under  increased temperature variability and nutrient enrichment than ungrazed  grasslands.\u00a0Our study highlights the importance of conserving  mammalian herbivore populations in grasslands worldwide. We need to  incorporate\u00a0local-scale herbivory, and its interaction with  nutrient enrichment and climate, within global-scale models to better  predict land-atmosphere interactions under future climate change.", "keywords": ["2.
