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 inferences are reliable, mtDNA phylogenies should be congruent with phylogenies based on other data. In previous work, a mtDNA phylogeny suggested that diversification of the Hawaiian cricket genus Laupala was initiated by single invasions into each of several Hawaiian islands, followed by multiple sympatric divergences…

Discordant mitochondrial and nuclear gene phylogenies in emydid turtles: implications for speciation and conservation
Do phylogenies and branch lengths based on mitochondrial DNA (mtDNA) provide a reasonable approximation to those based on multiple nuclear loci? In the present study, we show widespread discordance
Problems with mitochondrial DNA as a marker in population, phylogeographic and phylogenetic studies: the effects of inherited symbionts
It is concluded that these elements often confound the inference of an organism's evolutionary history from mtDNA data and that mtDNA on its own is an unsuitable marker for the study of recent historical events in arthropods.
Conflicting mitochondrial and nuclear phylogenies for the widely disjunct Emys (Testudines: Emydidae) species complex, and what they tell us about biogeography and hybridization.
It is argued that the invasion of Eurasia by Emys orbicularis occurred about 16 Ma via a trans-Beringian land bridge, which explains this discrepancy between mitochondrial and nuclear gene trees.
Introgression as a likely cause of mtDNA paraphyly in two allopatric skippers (Lepidoptera: Hesperiidae)
A unique case of mitochondrial DNA paraphyly in the skipper genus, Erynnis, that involves well-diverged allopatric species is described and it is suggested that similar processes could be operating in other taxa that have not been extensively sampled.
Testing mitochondrial sequences and anonymous nuclear markers for phylogeny reconstruction in a rapidly radiating group: molecular systematics of the Delphininae (Cetacea: Odontoceti: Delphinidae)
For closely related, recently diverged taxa, a multi-locus genome-wide survey is likely the most comprehensive approach currently available for phylogenetic inference.
Multiple nuclear gene sequences identify phylogenetic species boundaries in the rapidly radiating clade of Mexican ambystomatid salamanders
A expressed sequence tag database is made use of to perform nuclear and mitochondrial genealogical tests of species boundaries in Ambystoma ordinarium, a member of an adaptive radiation of metamorphic and paedomorphic salamanders that have diversified across terrestrial and aquatic environments to demonstrate how EST‐based nuclear resources can be used to more fully resolve the phylogenetic history of species radiations.
Genetic drift or natural selection? Hybridization and asymmetric mitochondrial introgression in two Caribbean lizards (Anolis pulchellus and Anolis krugi)
It is concluded that natural selection was the probable driving mechanism for the extensive k‐mtDNA introgression into the genome of A. pulchellus in western Puerto Rico.
Testing Species Boundaries in an Ancient Species Complex with Deep Phylogeographic History: Genus Xantusia (Squamata: Xantusiidae)
A revised taxonomic arrangement for this genus consistent with the distinct mtDNA lineages is presented and the phylogeographic history of this genus is discussed as a model system for studies of speciation in North American deserts.


Evolutionary history of an adaptive radiation in species pairs of threespine sticklebacks (Gasterosteus): insights from mitochondrial DNA
The data argue strongly that the species pairs have evolved independently in each lake were they now co-exist, arguing that natural selection acting on trophic ecology has been a major component of ecological speciation in sticklebacks.
Sympatric speciation suggested by monophyly of crater lake cichlids
A mitochondrial DNA analysis of cichlid species flocks endemic to two such lakes in Cameroon suggests that the flocks in each lake are monophyletic: the implication being that each lake was colonized once only, the size and shape of each lake being such that subsequent diversification would have been sympatric.
Genetic population structure indicates sympatric speciation of Lake Malawi pelagic cichlids
Mitochondrial DNA sequence data from 90 species, representing all major clades within the Lake Malawi flock, indicate reciprocal monophyly of the pelagic clade, suggesting that speciation in sympatry is more plausible (and widespread) within the cichlid species flocks than previously thought.
Speciation and phylogeography of Hawaiian terrestrial arthropods
The Hawaiian archipelago is arguably the world’s finest natural laboratory for the study of evolution and patterns of speciation. Arthropods comprise over 75% of the endemic biota of the Hawaiian
Species boundaries and genetic diversity among Hawaiian crickets of the genus Laupala identified using amplified fragment length polymorphism
The question of species boundaries in the Hawaiian cricket, Laupala, is addressed using nuclear DNA patterns sampled by the amplified fragment length polymorphism (AFLP) technique, which support previously hypothesized taxonomic relationships among sympatric populations and suggest close genetic relationships among allopatric, conspecific populations.
Molecular Markers, Natural History and Evolution
A history of Molecular Phylogenetics and applications of individuality and Parentage, issues of Heterozygosity, and special Approaches to Phylageny Estimation are reviewed.
Further acoustic diversity in Hawaiian forests: two new species of Hawaiian cricket (Orthoptera: Gryllidae: Trigonidiinae: Laupala).
Two new species of Laupala, endemic to the rain forested islands of the Hawaiian archipelago, are described, one from the Koolau Mountains of Oahu and another from Kipahulu Valley of East Maui, which produce the fastest and one of the slowest pulse rates in the genus.
Multiple Comparisons of Log-Likelihoods with Applications to Phylogenetic Inference
A modification of the KH test to take into account a multiplicity of testings is presented, which shows how the test was designed for comparing two topologies but is often used for comparing many topologies.
Speciation and Its Consequences
The purpose of this book is to illustrate how different patterns of speciation and differentiation have occurred among diverse taxa.

MacClade is a computer program that provides theory and tools for the graphic and interactive analysis of molecular and morphological data, phylogeny, and character evolution, yet its ease of use allows beginning students to grasp phylogenetic principles in an interactive environment.
