5. Global heterogeneity of the eco-evolutionary effect
We wondered if we could replace eco-evolution with a constant correction. Answer: no. Its effect is uneven—negligible in warm regions, but up to 2× more soil C loss in cold ones. Why? Optimal enzyme allocation responds nonlinearly. (6/7)

4. Implication for global soil C projections
We thought that microbial adaptation would buffer warming-induced soil C loss. But because it amplifies enzyme production (as shown above), we found that adaptation aggravates the loss—by x1.8 globally. (5/7)

2. Evolutionary result
We found that in hostile environments (e.g. high mortality, slow uptake), selection favors direct investment in biomass over the riskier strategy of enzyme production. Since warming mainly increases uptake rate, we predicted it would favor stronger enzyme producers. (3/7)

1. The eco-evolutionary model
We added a trade-off to a classic microbe-soil C model and used adaptive dynamics to evolve enzyme allocation. To prevent freeloaders from taking over, we included implicit spatial structure. Bonus: enzyme production emerges—it’s no longer a free parameter. (2/7)

New paper out in Global Change Biology 🤩
doi.org/10.1111/gcb....
We built the first soil carbon model that includes microbial eco-evolution using game theory — and found that adaptation could nearly double global soil carbon loss by 2100. Here is how👇(1/7)
