New preprint from our big collaborative evolution experiment in 9 whole lakes in Alaska, written by McGill grad student @lucaseckert.bsky.social
www.biorxiv.org/content/10.6...
What happens if you put a mixture of multiple source populations together to complete & evolve in multiple new lakes?

A drought nearly wiped out a protected population of unarmoured stickleback. Their numbers recovered, but their defining trait didn't: unarmoured fish went from 51% to ~15%. Conservation must protect the traits that make populations unique, not just their existence 🐟
