Ecological stoichiometry investigates the equilibrium and the fluxes of chemical elements and energy between organisms and their environment. Several studies have pointed out the value of integrating stoichiometric traits for a better understanding of the mechanisms behind community and ecosystem processes. Especially in the light of globally changing nutrient levels in freshwater systems, the link between stoichiometric traits and nutrient cycling or trophic interactions can improve our investigations of a species' or community's response to these changes. Benthic macroinvertebrate assemblages are widely used for biomonitoring in freshwaters, providing a large number of datasets gathering information about their taxonomic diversity at many different spatial and temporal scales. Likewise, an increasing number of large databases gives ready access to information on a variety of macroinvertebrate biological traits. The addition of stoichiometric traits to this pool of available information could thus expand the application of trait approaches and facilitate the study of the links between nutrient cycling and ecosystem functioning.

西欧水源大型无脊椎动物化学计量性状数据库

生态化学计量学研究生物与其环境之间的化学元素和能量的平衡和通量。一些研究指出了整合化学计量特征对于更好地理解群落和生态系统过程背后的机制的价值。特别是鉴于淡水系统中营养水平的全球变化，化学计量特征与营养循环或营养相互作用之间的联系可以改善我们对物种或社区对这些变化的反应的调查。底栖大型无脊椎动物组合广泛用于淡水中的生物监测，提供大量数据集，在许多不同的空间和时间尺度上收集有关其分类多样性的信息。同样地，越来越多的大型数据库可以随时访问有关各种大型无脊椎动物生物学特性的信息。因此，将化学计量性状添加到这一可用信息库中可以扩大性状方法的应用，并促进对养分循环和生态系统功能之间联系的研究。
