高通量测序技术，如宏基因组学和元转录组学技术，允许对微生物群落成员的功能特征以及它们的系统发育身份进行编目。这些研究发现，一个社区在生态相关的功能特征或行会方面的构成可以在不同的环境中比其组成在分类群方面更严格地保持。我使用一个标准的生态资源消费者模型来研究与资源消费相关的性状的动态，并分析功能结构的决定因素。该模型表明，与基本资源的相互作用可以调节整个社区的生态相关性状的丰度，保持在一致的水平，尽管在大的变化，在丰富的物种住房这些特征，以应对环境的变化，并在物种组成的社区之间的变化。功能结构被证明能够跟踪环境条件的差异，忠实地跨越物种组成的差异。消费者的生命率和功能反应的数学条件，必要和足够的保护功能群落结构在这些模型中的物种组成的差异。这些条件意味着生化率之间的非通用关系，并进一步研究的途径进行了讨论。
High-throughput sequencing techniques such as metagenomic and metatranscriptomic technologies allow cataloguing of functional characteristics of microbial community members as well as their phylogenetic identity. Such studies have found that a community’s makeup in terms of ecologically relevant functional traits or guilds can be conserved more strictly across varying settings than its composition is in terms of taxa. I use a standard ecological resource-consumer model to examine the dynamics of traits relevant to resource consumption, and analyze determinants of functional structure. This model demonstrates that interaction with essential resources can regulate the community-wide abundances of ecologically relevant traits, keeping them at consistent levels despite large changes in the abundances of the species housing those traits in response to changes in the environment, and across variation between communities in species composition. Functional structure is shown to be able to track differences in environmental conditions faithfully across differences in species composition. Mathematical conditions on consumers’ vital rates and functional responses necessary and sufficient to produce conservation of functional community structure across differences in species composition in these models are presented. These conditions imply a nongeneric relation between biochemical rates, and avenues for further research are discussed.
