No supergene despite social polymorphism in the big-headed ant Pheidole pallidula

E. Favreau, C. Lebas, E. Stolle, A. Priyam, R. Pracana, S. Aron, Y. Wurm

The paper investigates whether a supergene region determines social polymorphism in the big-headed ant Pheidole pallidula and finds no evidence of such a region.

Recurring adaptive introgression of a supergene variant that determines social organization

E. Stolle, R. Pracana, F. Lopez-Osorio, M. K. Priebe, G. L. Hernandez, C. Castillo-Carrillo, M. C. Arias, C. I. Paris, M. Bollazzi, A. Priyam, Y. Wurm

The paper shows a supergene variant for multiple-queen colonies in fire ants evolved in one species and spread to others via introgression.

Individual-based modeling of genome evolution in haplodiploid organisms

R. Pracana, R. Burns, R. L. Hammond, B. C. Haller, Y. Wurm

The paper develops an individual-based simulation model for haplodiploid species to study genetic evolution and finds that selection is more effective in these species than in diploids.

Degenerative expansion of a young supergene

E. Stolle, R. Pracana, P. Howard, C. I. Paris, S. J. Brown, C. A. Castillo-Carrillo, S. J. Rossiter, Y. Wurm

The paper shows that a young non-recombining region in fire ant social chromosomes has expanded in length by over 30%, demonstrating degenerative expansion during early evolution of non-recombining regions.
