- 1/ In our new paper, we explored whether obligate mutualisms can survive abrupt stress via evolutionary rescue. We found that evolutionary rescue is possible—but it comes at the cost of mutualism. @jfriedman.bsky.social #microsky #evosky #mevosky
- 2/ Over 80% of mutualistic consortia underwent evolutionary rescue. Yet intriguingly, the same strain consistently survived by regaining metabolic autonomy, while its partner went extinct. What factors determined which strain gained this adaptive advantage?
- 3/ We consider several factors: how easily metabolic autonomy is regained, and the role of demographic factors shaping population dynamics. These likely determine which strain survives—but why does gaining autonomy offer such an advantage?
