Silent crickets reveal the genomic footprint of recent adaptive trait loss

S. Pascoal, J. E. Risse, X. Zhang, M. Blaxter, T. Cezard, R. J. Challis, K. Gharbi, J. Hunt, S. Kumar, E. Langan, X. Liu, J. G. Rayner, M. G. Ritchie, B. L. Snoek, U. Trivedi, N. Bailey

The paper examines the genomic effects of recent sexual signal loss in crickets, finding pleiotropy, hitchhiking, and regulatory disruption associated with the trait loss.

Genomic architecture and introgression shape a butterfly radiation

N. B. Edelman, P. Frandsen, M. Miyagi, B. J. Clavijo, J. Davey, R. Dikow, G. Garcia Accinelli, S. M. Van Belleghem, N. J. Patterson, D. E. Neafsey, R. J. Challis, S. Kumar, G. R. P. Moreira, C. Salazar, M. Chouteau, , J. Mallet

The paper uses a low-cost genome assembly strategy to study Heliconius butterfly evolution, finding that introgression, not incomplete lineage sorting, explains most non-canonical genetic histories.
