我们利用坦桑尼亚基利曼哈罗山广泛的气候和土地利用梯度，研究地面觅食蚂蚁群落中营养物质利用的大规模变化。特别是，我们测试了这样一个假设，即蚂蚁对六种不同营养物质的吸收会随着海拔和土地利用制度的不同而变化。我们还测试了蚂蚁使用的营养空间（营养物质的数量和均匀度）是否随着物种丰富度随海拔的下降而减少，这种模式是由于物种营养摄入的互补性而预期的。
We used the extensive climatic and land‐use gradient on Mt Kilimanjaro, Tanzania, to study large‐scale variation of nutrient use in ground‐foraging ant communities. In particular, we tested the hypothesis that recruitment of ants to six different nutrients would vary with elevation and between land‐use regimes. We also tested whether the nutrient space (number and evenness of nutrients) used by ants decreases as species richness declines with elevation, a pattern expected because of complementarity in nutritional intake of species.
