Soil and Microbial Controls Jointly Regulate Elevational Patterns of Free‐Living Nitrogen Fixation Rate and Its Temperature Sensitivity

in colder zones also suggests that warming may have a more profound impact on N inputs in nutrient-limited high-elevation and high-latitude ecosystems, although this effect is likely contingent on soil resource availability. We emphasize the importance of incorporating diazotrophic community structure and thermal traits into global biogeochemical models to improve predictions of future nitrogen budgets.
