Work from @brynnjohnson13.bsky.social's thesis investigates why neighboring hybrid zones between orangethroat and orangebelly darters followed different trajectories: long-term coexistence vs. collapse. Warming amplifies competitive asymmetry, influencing whether hybrid zones persist or collapse.

Does #SexualSelection fuel #Speciation?

Our new #meta-analysis of comparative studies finds support for a positive relationship, but the rather moderate global effect suggests it’s not necessarily a dominant force.
