In this new paper, @albertbrangari.bsky.social develops a new theoretically grounded approach to represent both microbial growth and respiration in a unified framework that can be interfaced immediately into Earth System Models framework, thus incorporating ecological insights into biogeochemistry

...and that the temperature relationships for microbial growth and respiration actually differ (onlinelibrary.wiley.com/doi/full/10...., journals.asm.org/doi/10.1128/...), and are climate dependent (journals.asm.org/doi/10.1128/...), and can adapt to warming (onlinelibrary.wiley.com/doi/full/10....)

A Summer heat wave in the Subarctic resulted in shifted microbial communities toward those that grow better at high temperatures. This shift persisted for a year after the heat wave ended. The heat w...
