Evolutionary History Influences The Salinity Preference Of Bacterial Taxa In Wetland Soils, Ember M. Morrisey, Rima B. Franklin Jan 2015

Evolutionary History Influences The Salinity Preference Of Bacterial Taxa In Wetland Soils, Ember M. Morrisey, Rima B. Franklin

Salinity is a major driver of bacterial community composition across the globe. Despite growing recognition that different bacterial species are present or active at different salinities, the mechanisms by which salinity structures community composition remain unclear. We tested the hypothesis that these patterns reflect ecological coherence in the salinity preferences of phylogenetic groups using a reciprocal transplant experiment of fresh- and saltwater wetland soils. The salinity of both the origin and host environments affected community composition (16S rRNA gene sequences) and activity (CO2 and CH4 production, and extracellular enzyme activity). These changes in community composition and activity rates were …
