| 英文摘要 | Varied interspecific interactions have a tremendous impact on the population dynamics of related species. However, the context dependency of interspecific interactions and their ecological effects have not been well-characterized. To understand the context dependency of ant-aphid mutualism and the corresponding ecological effects, we explored the association of ant abundance, trophic position, and plant herbivory along an elevational gradient. We hypothesized that a higher abundance of ants would be associated with a lower trophic position and lower plant herbivory level along the gradient. We detected a large variation in ant abundance and herbivory along the elevational gradient. Consistent with our prediction, a higher ant abundance was associated with a lower trophic position, and herbivory decreased linearly with ant abundance. A tight positive relationship between the abundance of ants and aphids was observed. These findings suggest that the context dependency of ant-aphid mutualism can be an important factor affecting the pattern of ant abundance and plant herbivory across the elevational gradient. This study highlights the significance of mutualistic interactions in shaping the pattern of certain key ecological processes, such as herbivory, at a relatively larger spatial scale. |
