It has been asserted that recent mtDNA phylogenies support the plausibility of sympatric
speciation, long considered a controversial mechanism of the origin of species. If such …

The tremendous diversity of endemic Hawaiian crickets is thought to have originated
primarily through intraisland radiations, in contrast to an interisland mode of diversification in …

Crickets of the genus Laupala represent one of the many morphologically cryptic groups of
insects, with the most closely related species distinguished only by the male calling song …

Population genetics theory predicts that genetic drift should eliminate shared polymorphism,
leading to monophyly or exclusivity of populations, when the elapsed time between lineage …

We have examined mitochondrial DNA (mtDNA) restriction-site variation within and between
populations of fall-adult field crickets across a narrow hybrid zone in Connecticut. Our …

A well-supported molecular phylogeny for North American Gryllus species based on a
combined data set of mitochondrial (mt) DNA is presented. A total of 26 individuals …

Harnessing the power of genomic scans, we test the debated “species pump” hypothesis
that implicates repeated cycles of island connectivity and isolation as drivers of divergence …

Evolutionary history of Muscicapidae flycatchers is inferred from nuclear and mitochondrial
DNA (mtDNA) sequence comparisons and population genetic analysis of nuclear and …

Oceanic islands have played a central role in biogeography and evolutionary biology. Here,
we review molecular studies of the endemic terrestrial fauna of the Hawaiian archipelago …

An accurately resolved gene tree may not be congruent with the species tree because of
lineage sorting of ancestral polymorphisms. DNA sequences from the mitochondrially …
