Experimental introgression in Drosophila: asymmetric postzygotic isolation associated with chromosomal inversions and an incompatibility locus on the X chromosome

This study investigates genetic incompatibilities in Drosophila species by analyzing introgression patterns and finds reduced introgression on the X chromosome in reciprocal backcrosses.

Divergence and introgression among the virilis group of Drosophila

The paper examines introgression and divergence patterns in the virilis group of Drosophila using genome data, finding three subgroups, ancient introgression, and gene flow impacts on adaptation and speciation.

Cold adaptation drives population genomic divergence in the ecological specialist, Drosophila montana

This study identifies genomic signatures of cold adaptation in Drosophila montana by linking genetic differentiation to climatic variables and phenotypic traits.

Multiple paths to cold tolerance: the role of environmental cues, morphological traits and the circadian clock gene vrille

This study investigates cold tolerance in two Drosophila species, linking it to environmental cues, morphology, and the circadian gene vrille, finding vrille's role in cold resistance and acclimation.

Reinforcement targets sexual or postmating prezygotic reproductive barriers depending on species abundance and population history

The paper examines how reinforcement of reproductive barriers varies between species based on abundance and population history, showing different targets in sympatric and invasive populations.
