Evidence of parental care as a novel reproductive isolating mechanism

Colby Behrens, Meghan F. Maciejewski, Alexandra X. Sumarli, Gina Lucas, German Lagunas‐Robles, Kieran Samuk, Alison M. Bell

This study shows that dysregulated parental care in hybrid stickleback fish leads to reduced offspring survival, suggesting it acts as a postzygotic reproductive isolating mechanism.

Expanded unbiased population-genomic summary statistics in pixy

Kieran Samuk, Matt Stone, Erin McAuley, Nicholas P. Bailey, Gina Lucas, Mikhail Plaza

The paper updates the pixy software to compute unbiased population-genomic summary statistics from all-sites VCFs, supporting new estimators, ploidy, multiallelic sites, and optimizations.

Strong but diffuse genetic divergence underlies differentiation in an incipient species of marine stickleback

Alexandra X. Sumarli, Colby Behrens, Gina Lucas, Michael J. Olufemi, Paul Bentzen, Alison M. Bell, Frédéric J. J. Chain, Kieran Samuk

This study examines genomic divergence between two sympatric marine stickleback ecotypes, finding widespread low differentiation and recent divergence with limited gene flow.
