TY  - JOUR
AB  - Understanding  how  the  metabolic  rates  of  prokaryotes  respond  to  temperature  is  fun-damental  to  our  understanding  of  how  ecosystem  functioning  will  be  altered  by  climatechange, as these micro-organisms are major contributors to global carbon efflux.  Ecologicalmetabolic theory suggests that species living at higher temperatures evolve higher growthrates than those in cooler niches due to thermodynamic constraints.  Here, using a globalprokaryotic dataset, we find that maximal growth rate at thermal optimum increases withtemperature for mesophiles (temperature optima.45C), but not thermophiles (&45C).Furthermore, short-term (within-day) thermal responses of prokaryotic metabolic rates aretypically more sensitive to warming than those of eukaryotes.  Because climatic warmingwill mostly impact ecosystems in the mesophilic temperature range, we conclude that asmicrobial communities adapt to higher temperatures, their metabolic rates and therefore,biomass-specific  CO2production,  will  inevitably  rise.   Using  a  mathematical  model,  weillustrate the potential global impacts of these findings.
