Interpreting the genomic landscape of speciation: a road map for finding barriers to gene flow
Speciation, the evolution of reproductive isolation among populations, is continuous,
complex, and involves multiple, interacting barriers. Until it is complete, the effects of this …

Coupling of barriers to gene exchange: causes and consequences
Coupling has emerged as a concept to describe the transition from differentiated
populations to newly evolved species through the strengthening of reproductive isolation …

Evolution of polygenic traits under global vs local adaptation
S Yeaman - Genetics, 2022 - academic.oup.com
Observations about the number, frequency, effect size, and genomic distribution of alleles
associated with complex traits must be interpreted in light of evolutionary process. These …

Coupling, reinforcement, and speciation
During the process of speciation, populations may diverge for traits and at their underlying
loci that contribute barriers to gene flow. These barrier traits and barrier loci underlie …

Inversion invasions: when the genetic basis of local adaptation is concentrated within inversions in the face of gene flow
Across many species where inversions have been implicated in local adaptation, genomes
often evolve to contain multiple, large inversions that arise early in divergence. Why this …

Genomics of hybridization and its evolutionary consequences
Hybridization and its consequences have been of longstanding interest to evolutionary
biologists. Darwin (1859) included a chapter on hybrids and the expression and causes of …

Transitions between phases of genomic differentiation during stick-insect speciation
Speciation can involve a transition from a few genetic loci that are resistant to gene flow to
genome-wide differentiation. However, only limited data exist concerning this transition and …

Negative coupling: the coincidence of premating isolating barriers can reduce reproductive isolation
Speciation can be mediated by a variety of reproductive barriers, and the interaction among
different barriers has often been shown to enhance overall reproductive isolation, a process …

Parallelism in eco-morphology and gene expression despite variable evolutionary and genomic backgrounds in a Holarctic fish
Understanding the extent to which ecological divergence is repeatable is essential for
predicting responses of biodiversity to environmental change. Here we test the predictability …
