Great to see the final paper of Bonnie Waring's dissertation out: Ecological mechanisms underlying soil bacterial responses to rainfall along a steep natural precipitation gradient. Bonnie addressed bacteria turnover and specialization using a common garden approach with soil transplanted across our central Texas rain gradient. Bacteria were highly resistant to change and this appears to constrain soil respiration responses to altered rainfall.

postdoctoral researcher to work on a USDA-funded project studying how fungal endophytes control plant drought responses in switchgrass, sorghum, and maize. The goal of the project is to develop a mechanistic framework for predicting fungal effects on plants at scale.
Our first paper from Stephanie Kivlin's postdoctoral work is out in Environmental Microbiology. Using experimental tree monocultures, we found that soil fungal communities diverge among tree species and spatial heterogeneity associated with tree species. However, fungal abundance varies seasonally, despite small differences in climate and soil moisture. For more information, see http://onlinelibrary.wiley.com/doi/10.1111/1462-2920.13342/abstract
