Microbial And Co2 Responses To Water Stresses Show Decreased Productivity And Diversity Through Time, David Michael Robinson

Theses and Dissertations

Some bacterial taxa when stimulated by water additions will break dormancy, grow, and become dominant members of the community and contribute significant pulses of CO₂ associated with the rewetting event. These pulses of activity are associated with high levels of bacterial productivity in soils. (Aanderud et al. 2011) We examined the bacterial taxa that resuscitate and become metabolically active following two forms of water stress (soil drying-rewetting and freeze-thaw cycles) and we captured and measured the CO₂ emanating from those soils. Specifically, We used target metagenomics, which uses a specific gene pool within bacteria that is associated with …
