In this compelling episode, we sit down with Dr. Allison, a trailblazer in environmental microbiology, to discuss his recent paper on the increasing frequency and intensity of droughts due to climate change and their impact on soil microbes and carbon loss. Dr. Allison illuminates how soil microbes, the unsung heroes of carbon cycling, respond to drought through physiological acclimation, dispersal, shifts in community composition, and evolutionary adaptation. As decomposers, these microbes control the loss of carbon from the soil.

The conversation takes a deep dive into microbial drought resistance dynamics, including fascinating tolerance and avoidance mechanisms. Dr. Allison elaborates on how physiological responses allow microbes to acclimate to drought within mere minutes to days. Alongside dispersal, changes in microbial community com ...
