已知生物的多样性和功能特性与生态系统进程的维持有关，但在不同的环境中可能有所不同。特别是，生态系统进程是由互补效应还是由占优势的物种群体驱动的，目前尚不确定。我们调查了社区结构（即，生物实体的多样性和相对丰度）解释了新热带区蚂蚁群落对不同环境中不同生态系统过程的群落级贡献。蚂蚁被吸引的食物资源，代表六个蚂蚁介导的生态系统过程中的四个环境：地面和植被层在农田和森林栖息地。诱饵的利用频率用于计算蚂蚁群落的分类和营养结构以及它们对单独或组合考虑的生态系统过程的贡献（即，多功能性）。然后，我们调查了社区结构变量是否可以预测生态系统过程，以及这种关系是否受到环境的影响。我们发现，森林呈现出更大的生物多样性和营养互补性和较低的优势比农田，但这并不影响生态系统过程。相比之下，营养互补性是更大的地面比植被，其次是更大的资源开发水平。虽然蚂蚁参与生态系统过程可以预测的营养为基础的指数，我们发现，在生态系统过程中的社区结构和性能的变化最好的解释环境。我们的结论是，确定在何种程度上的优势和互补性的社区影响生态系统过程在不同的环境中需要更好地了解不同物种的资源可用性。
The diversity and functional identity of organisms are known to be relevant to the maintenance of ecosystem processes but can be variable in different environments. Particularly, it is uncertain whether ecosystem processes are driven by complementary effects or by dominant groups of species. We investigated how community structure (i.e., the diversity and relative abundance of biological entities) explains the community-level contribution of Neotropical ant communities to different ecosystem processes in different environments. Ants were attracted with food resources representing six ant-mediated ecosystem processes in four environments: ground and vegetation strata in cropland and forest habitats. The exploitation frequencies of the baits were used to calculate the taxonomic and trophic structures of ant communities and their contribution to ecosystem processes considered individually or in combination (i.e., multifunctionality). We then investigated whether community structure variables could predict ecosystem processes and whether such relationships were affected by the environment. We found that forests presented a greater biodiversity and trophic complementarity and lower dominance than croplands, but this did not affect ecosystem processes. In contrast, trophic complementarity was greater on the ground than on vegetation and was followed by greater resource exploitation levels. Although ant participation in ecosystem processes can be predicted by means of trophic-based indices, we found that variations in community structure and performance in ecosystem processes were best explained by environment. We conclude that determining the extent to which the dominance and complementarity of communities affect ecosystem processes in different environments requires a better understanding of resource availability to different species.
