Microbial Functional Redudnacy of Esturine Microbiome

Background

Species respond in diverse ways to the challenges in their habitat. The strength and formation of this response depend on the extent of redundancy within the community or system. ​Differences in microbial communities, how they respond under stress, and their composition become apparent when comparing two geographically similar and biologically distinct systems. ​

Estuaries are dynamic ecosystems where rapidly changing environmental factors, including extreme climate and human activities, cause irreversible degradation, making them ideal models to study microbial responses to variations or disturbances.​

Here, we used metagenomics and metatranscriptomics of 20 seasonal samples combined with a genome-resolved approach, whose genomes represented between 46 to 92% of the bacterial and archaeal community to profile microbial composition, metabolic potential, and microbial functional redundancy (FRed) in the Chesapeake and Delaware Bays, USA.
