awesome work by @junishigohoka.bsky.social highlighting the underappreciated role of shifting balancing selection. jun used demography inference, pogen simulation under our blackcap demography, and ABC to (i) identify the type of balancing selection and (ii) estimate its spatially varying parameters

Divergent selection is the textbook explanation for narrow inversion clines.
Our blackcap inversion cline doesn't fit: it is wide, and the inversion is always the rarer arrangement. We show that negative frequency-dependent selection shifting between populations underlies this!
We investigated what factor contributes to a cline of a chromosomal inversion of the Eurasian blackcap, which differs from typical inversion clines maintained by divergent selection. Using a simulati...
