| 内容記述 | 1. Plant-herbivore interactions can be important factors affecting ecosystem functions. Herbivorous insects may have significant impacts on litter decomposition through modification of plant litter quality and quantity. However, our knowledge about the effects of herbivorous insects on the decomposition process is very limited. 2. Here, we conducted experiments to examine how sap-feeding aphids modify plant litter and whether the aphid-induced modification influences litter decomposition processes, using a plant-herbivore system consisting of a soybean (Glycine max) and soybean aphids (Aphis glycines). 3. First, litter traits produced by aphid-free and aphid-infected plants were compared, and we found that aphids did not affect litter mass and carbon concentration, but significantly decreased nitrogen and increased phenolic concentrations. Such aphid-mediated modification of litter quality may cause deceleration of litter decomposition since litter nitrogen promotes decomposition and litter phenolics inhibit it. 4. Then, we carried out a decomposition experiment to compare decomposition processes of litter between the aphid-free and aphid-infected plants. We found no impacts of aphid herbivory on litter carbon mineralization but negative impacts on nitrogen mineralization. Litter nitrogen mineralization of aphid-infected plants decreased by 40 and 28% compared to that of aphid-free plants one and three months after commencement of the experiment, respectively. 5. Our experimental results clearly showed that aphids decelerated litter nitrogen mineralization by modifying litter quality, suggesting that aphids can play a critical role in nitrogen flux between above- and below-ground ecosystems. | |||||
