Alejandro Salazar, post doctoral researcher at the Faculty of Life and Environmental Sciences, will present his work:
Global soil respiration, the largest flux of carbon from terrestrial ecosystems to
the atmosphere, is primarily driven by soil microbes. I will talk about how by
entering and exiting dormancy, a process generally ignored when modelling the Earth
system, microbes affect soil carbon-climate feedbacks. I'll show empirical evidence
about how activation of dormant microbes in soil increases soil respiration rates,
and model simulations that suggest that this could results in larger soil carbon
emissions than current estimations, especially under warming and dry conditions.
