This study evaluates genomic offset (GO) as a predictor of population trends in Lycaeides butterflies and finds it is not a reliable predictor despite methodological variations.

The paper examines hybridization and color polymorphism in Colias butterflies over five years, finding hybrid ancestry correlates with intermediate phenotypes but not exclusively.

The paper examines genetic differentiation between two sympatric populations of an alpine butterfly collected in odd and even years, finding clear genetic separation and limited admixture.

This study shows that admixture in Lycaeides butterflies leads to distinct evolutionary histories across chromosomes, with the Z chromosome showing more tree-like patterns than autosomes.

The paper shows that additive genetic effects from both plants and caterpillars determine the outcome of herbivory on alfalfa, with plant phytochemicals playing a key role.
