Through our lives we face tradeoffs in the way we allocate resources (e.g. time, money) towards maximizing our relevant objective functions: happiness, professional development, health, etc. This happens not only at the individual level but also to organizations, societies and countries. Anyone who has ever played strategy games (e.g. Age of Empires) know this well, how you use your resources to grow your economy and your military decides your fate in the game.
It turns out that something similar occurs to communities of bacteria in wastewater treatment bioreactors when faced against varying perturbations, as we show in our most recent study published at Environmental Microbiology: http://bit.ly/Santillan2019-EnvMicro
Towards our ultimate goal of managing complex microbial communities , we employed a life-history strategy framework from plant ecology [2, 3] to enable the simpliﬁcation of complex trait information into a few ecologically relevant elements, while at the same time offering a suitable management tool for characterizing changes in community structure and ecosystem function in response to perturbations.
The results from this work are relevant for microbial ecology as they represent the ﬁrst time that Competitor – Ruderal – Stress-tolerant life-history strategies are (i) proposed at the whole-community level by assessing community aggregated traits; (ii) supported by a combination of ordination methods, network analysis, and genotypic information from metagenomics and 16S rRNA gene amplicon sequencing; and (iii) evaluated for complex microbial communities in an environment other than soil.
