Project description:Monitoring microbial communities can aid in understanding the state of these habitats. Environmental DNA (eDNA) techniques provide efficient and comprehensive monitoring by capturing broader diversity. Besides structural profiling, eDNA methods allow the study of functional profiles, encompassing the genes within the microbial community. In this study, three methodologies were compared for functional profiling of microbial communities in estuarine and coastal sites in the Bay of Biscay. The methodologies included inference from 16S metabarcoding data using Tax4Fun, GeoChip microarrays, and shotgun metagenomics.
Project description:Gene expression was measured in the gills of saltwater (SW) acclimated Atlantic Killifish, Fundulus heteroclitus, over a time course of freshwater (FW) exposure, in which half the fish were exposed to arsenic. Fish were sampled from three populations, two from Maine, USA (ME) and one from Virginia, USA (VA)
