Multiple paternity and competition in sympatric congeneric reef fishes, Embiotoca jacksoni and E. lateralis.

abstract：:Genetic divergence of populations in the presence of gene flow is a central theme in speciation research. Theory predicts that divergence can happen with full range overlap - in sympatry - driven by ecological factors, but there are few empirical examples of how ecologically divergent selection can overcome gene flow ...

abstract：:Copy number variants (CNVs) are a major component of genotypic and phenotypic variation in genomes. To date, our knowledge of genotypic variation and evolution has largely been acquired by means of single nucleotide polymorphism (SNPs) analyses. Until recently, the adaptive role of structural variants (SVs) and partic...
