为了增加生物多样性生态系统功能理论的普遍性，研究必须扩大到包括各种系统中的真实的群落。我们修改了J. W。福克斯的方法划分的影响，物种丰富度的现存作物生物量（净生物多样性效应）的21个淡水贻贝社区的性状独立的互补性，性状依赖的互补性（物种与特定性状占主导地位，而不影响其他物种），和优势效应（物种与特定性状占主导地位，牺牲他人）。总体而言，物种丰富的贻贝社区有更大的生物量比预测的平均生物量在整个地区。这种影响主要是由于性状独立的互补性与较少丰富的物种具有较高的身体状况和减少的代谢率在物种丰富的社区。这些措施是正相关的空间和时间的热变化，这表明，使用热生态位作为栖息地可能是重要的物种共存和性能，并强调，物种特征和环境背景的知识是很重要的了解生物多样性生态系统功能动态。
To increase the generality of biodiversity-ecosystem function theory, studies must be expanded to include real communities in a variety of systems. We modified J. W. Fox's approach to partition the influence of species richness on standing crop biomass (net biodiversity effect) of 21 freshwater mussel communities into trait-independent complementarity, trait-dependent complementarity (species with particular traits dominate without impacting other species), and dominance effects (species with particular traits dominate at the expense of others). Overall, species-rich mussel communities have greater biomass than predicted based on average biomass across the region. This effect is largely due to trait-independent complementarity with less abundant species having higher body condition and reduced metabolic rates in species-rich communities. These measures are positively correlated with spatial and temporal thermal variation, suggesting that use of thermal niches as habitat may be important to species coexistence and performance, and emphasizing that knowledge of species traits and environmental context are important to understanding biodiversity-ecosystem function dynamics.
