AI Article Synopsis
- Microorganisms play a crucial role in breaking down soil carbon, and their activity can change with rising temperatures, potentially influencing climate change.
- This study investigates how different bacterial groups from various climates (Arctic, boreal, temperate, and tropical) respond to temperature changes, revealing that each group's growth sensitivity to temperature varies.
- The research indicates that the traits of these bacterial communities can help predict how carbon cycling will respond to climate change globally.
Article Abstract
Microorganisms drive soil carbon mineralization and changes in their activity with increased temperature could feedback to climate change. Variation in microbial biodiversity and the temperature sensitivities (Q) of individual taxa may explain differences in the Q of soil respiration, a possibility not previously examined due to methodological limitations. Here, we show phylogenetic and taxonomic variation in the Q of growth (5-35 °C) among soil bacteria from four sites, one from each of Arctic, boreal, temperate, and tropical biomes. Differences in the temperature sensitivities of taxa and the taxonomic composition of communities determined community-assembled bacterial growth Q, which was strongly predictive of soil respiration Q within and across biomes. Our results suggest community-assembled traits of microbial taxa may enable enhanced prediction of carbon cycling feedbacks to climate change in ecosystems across the globe.
