I've got a quick question for the friendly microbiologists of Mastodon. It's my understanding that it's common for some environmental change to wipe out 90+% of a bacterial colony, only to have the survivors quickly multiply back to their original numbers, this time with a mutation that grants resistance to whatever the threat was. Is there a name for this phenomenon (not "gene fixation," but the die back and recovery)? Are there canonical papers about it? EDIT: I think "population bottleneck" is the best way to describe what I mean, though I got a few other very good suggestions for related terms. Thanks everyone! You guys are the best. ❤️ #microbiology #bacteria
