Genome-wide DNA methylation predicts environmentally-driven life history variation in a marine fish

H. Cayuela, C. Rougeux, M. Laporte, C. Merot, E. Normandeau, M. Leitwein, Y. Dorant, K. Praebel, E. Kenchington, M. Clement, P. Sirois, L. Bernatchez

This study shows that DNA methylation patterns differ between two life history strategies in capelin, suggesting epigenetic changes, not genetic differences, drive these variations.

Spotting genome-wide pigmentation variation in a brown trout admixture context

T. VALETTE, M. LEITWEIN, J.-M. LASCAUX, E. DESMARAIS, P. BERREBI, B. GUINAND

The paper identifies 337 colour patterning loci associated with pigmentation traits in brown trout using SNP data and GWAS, revealing a polygenic basis and implications for admixture management.

The role of recombination on genome-wide patterns of local ancestry exemplified by supplemented Brook Charr populations

M. Leitwein, H. Cayuela, A.-L. Ferchaud, E. Normandeau, P.-A. Gagnaire, L. Bernatchez

The paper examines how recombination affects local ancestry patterns in Brook Charr populations following hybridization, finding that deleterious mutations influence introgression dynamics.

Adaptive and maladaptive genetic diversity in small populations; insights from the Brook Charr (Salvelinus fontinalis) case study

A.-L. Ferchaud, M. Leitwein, M. Laporte, D. Boivin-Delisle, B. Bougas, C. Hernandez, E. Normandeau, I. Thibault, L. Bernatchez

The paper examines genetic diversity in Brook Charr populations, finding increased deleterious mutations in isolated populations and environmental associations with adaptive loci.
