Soil microbial moisture dependences and responses to drying–rewetting: The legacy of 18 years drought

Abstract: Climate change will alter precipitation patterns with consequences for soil C cycling. An understanding of how fluctuating soil moisture affects microbial processes is therefore critical to predict responses to future global change. We investigated how long‐term experimental field drought influences microbial tolerance to lower moisture levels (“resistance”) and ability to recover when rewetted after drought (“resilience”), using soils from a heathland which had been subjected to experimental precipitation red… Show more

“…It is well known that drought can strongly affect plant growth and soil microbial community activity and composition, resulting in altered rates of C and N cycling processes (Gordon et al, 2008;Sanaullah et al, 2011;, 2018de Nijs et al, 2019). Similar to elevated CO 2 and grazing, root exudates have been hypothesized to play an important role in the response of soil microbial communities to drought, but it is challenging to disentangle root-exudate-mediated effects from other mechanisms through which drought affects soil microbial communities.…”

“…Similar to respiration, microbial growth is stimulated by re-wetting after drought, although usually delayed by hours relative to the respiratory response (Blazewicz, Schwartz, & Firestone, 2014;de Nijs et al, 2019;Meisner, Bååth, & Rousk, 2013).…”

“…The third type of disturbance was exerted onto the mat community in spring 2014 and autumn 2015, when a previously dormant river was again reactivated after a period of cold and drought by high water inflow. This rewetting event conditioned new possibilities for substrate colonization resulting in the formation of a newly colonized mats (de Nijs, Hicks, Leizeaga, Tietema & Rousk, ; Schimel, Balser & Wallenstein, ). During these water inflow periods, mat community had a low overall diversity and species richness with mat being almost solely represented by cyanobacteria (around 90% of the total community).…”
