Abstract

Soil microbes are key regulators of Earth's biogeochemical cycles, and their growth, turnover, and efficiency are important controls of organic matter decay and soil carbon (C) storage. A central roadblock to scaling microbial activity is explaining the incongruence between long- and short-term warming responses. In addition to the well-described kinetics which dominate the short-term warming response, the long-term response is also subject to indirect effects, such as substrate availability, soil moisture, and shifts in plant community composition, that influence microbial activity and community dynamics. Here we discuss possible mechanisms of this attenuation, synthesized in the context of five testable hypotheses, presented in order of decreasing current empirical support.
