Admixture mapping among three hybridizing sapsucker (Sphyrapicus) species shows importance of the Z chromosome in phenotypic differentiation and speciation

The paper uses admixture mapping to identify Z-chromosome regions associated with plumage color variation in hybridizing sapsucker species.

Magic traits, search costs, and the persistence of species in secondary contact

The paper simulates secondary contact between populations to show how search costs and pleiotropy affect mating trait differentiation and species persistence.

The Driving W Hypothesis as an Explanation for Low Within-Population Mitochondrial DNA Diversity and Between-Population Mitochondrial Transfer

The paper proposes and evaluates the W-mtDNA Drive Hypothesis to explain low within-population mitochondrial DNA diversity and between-population mitochondrial transfer.

Population genomic analyses reveal a highly differentiated genetic cluster of northern goshawks (Accipiter gentilis laingi) in Haida Gwaii

The paper identifies a distinct genetic cluster of northern goshawks in Haida Gwaii using genomic data and develops targeted assays to confirm its isolation.

Comparative analysis examining patterns of genomic differentiation across multiple episodes of population divergence in birds

The paper examines genomic differentiation patterns across eight bird sister pairs, finding correlations between differentiation metrics and genomic features like gene density, with higher repeatability in more reproductively isolated pairs.

Recurrent selection explains parallel evolution of genomic regions of high relative but low absolute differentiation in greenish warblers

The paper investigates genomic differentiation in greenish warblers, finding that regions of high relative but low absolute differentiation are explained by recurrent selection rather than phylogenetic factors.
