Microbes play a critical role in plant litter decomposition and influence the fate of carbon in rivers and riparian zones. When decomposing low‐nutrient plant litter, microbes acquire nitrogen (N) and phosphorus (P) from the environment (i.e., nutrient immobilization), and this process is potentially sensitive to nutrient loading and changing clima...
Article
The relative importance of topography and vegetation in shaping local soil invertebrate communities is poorly understood. We investigated changes in the species and trait compositions of Collembola communities associated with different topography and forest types. Our study sites encompassed various topographies with different slope aspects and for...
Article
The responses of forest production and nitrogen (N) utilization to belowground resource availability may be stronger in Moso bamboo forests than in woody forests because the former have higher N and water demands than the latter. The aim of this study was to clarify the different effects of mountain slope-induced belowground resource limitation on...
