Phylogenetic Relationships of Tick Species in the <em>Ixodes ricinus</em> Complex, Derived from Mitochondrial Coi and 16S Genes
… worldwide using nucleotide sequences from mitochondrial cytochrome oxidase subunit I (mtDNA COI), and mitochondrial (mt) 16S genes. Ten species from the complex were analyzed; a 504bp fragment was amplified from the mt 16s gene and a 1080pb fragment from mtDNA COI gene. The inferred …

Host-parasite cophylogeny and rates of evolution in two rodent-louse assemblages
… of cophylogeny when compared to their hosts. The mitochondrial COI gene of lice of the G. coronadoi complex is evolving approximately 2 -3 times faster than the COI gene of their hosts, whereas the COI gene of lice of the G. mexicanus complex is evolving at roughly the same rate as the same gene …

Phylogeography of Darlingtonea Kentuckensis and Molecular Systematics of Kentucky Cave Trechines
… northern Tennessee. DNA sequence data from the mitochondrial gene cytochrome oxidase subunit I (COI) was collected from one to four individuals from 27 populations, and patterns of phylogeography and population structure were inferred from COI haplotypes. A hierarchical analysis of molecular …

Phenotypic and Genetic Diversity in the Sea Urchin Lytechinus Variegatus
… regions and congruence between the phylogenetic mitochondrial COI data and color phenotypes seen in the field.</p><p>The distribution of color phenotypes in the field is highly variable across the geographic range which stretches from Beaufort NC to southern Brazil and throughout the Gulf of …

Genetic differentiation of the parasitoid, Cotesia congregata (Say), based on host-plant complex
… America using seven microsatellite loci and the mitochondrial COI locus. Microsatellite allele frequencies were differentiated based on host-plant complex, and COI haplotypes from individuals on the same host-plant were identical despite geographic distances between catalpa sites of up to 830 km …

Morphological, ecological and molecular examination of the seacucumber species along the Red Sea coast of Egypt and Gulf of Aqaba : with the investigation of the possibility of using DNA barcoding technique as a standard method for seacucumber ID
… the Red Sea using the molecular analysis of the mitochondrial COI gene.In this study another experiment were conducted in order to identify sea cucumber species from cooked or dried materials using the molecular techniques. As well as testing the possibility of using the DNA barcoding technique …

Resolution of the Marthasterias Taxonomic "Disar-star"
… be genetically indistinguishable, using both a mitochondrial COI sequence and a nucleic ITS1 gene. The COI and ITS sequences of the South African specimens were also compared to that from European specimens, and the p-value distances of 4% and 3% respectively show a significant distinction …

Population genetics and systematics of a species-rich clade of Neotropical reef fishes, the tubeblenny genus Acanthemblemaria
… of these fishes. By combining nuclear and mitochondrial sequence data I was able to recover the complex demographic history of two closely related Acanthemblemaria species, A. aspera and A. spinosa. Old population expansions in both species were obscured by a rapid mitochondrial …

Macrogeographic Genetic Structure in Acanthephyra curtirostris (Oplophoridae)
… of individuals sequenced for a 635 bp of the mitochondrial COi gene, and a population survey using two microsatellite markers developed for this study, detected substantial genetic diversity among the sampled locations. Unique mitochondrial haplotypes were detected in the Hawaiian population …

MATING COSTS, MALE CHOICE DISPLACEMENT, AND THE EFFECTS ON HYBRIDIZATION AND SPECIATION IN THE HAWAIIAN CRICKET LAUPALA (SUBFAMILY:TRIGONIDIINAE)
… L. pacifica species pair. First, by using the mitochondrial COI gene and AFLPs as genetic markers, I demonstrated that there appears to be mitochondrial DNA introgression between sympatric, but not allopatric congeners, which suggests contemporary hybridization in the contact zone. Next, I …

The taxonomy, systematics and biogeography of the austral horse fly tribe scionini (Diptera : Tabanidae)
… An alignment of six molecular markers, including mitochondrial (COI and COII), ribosomal (28S) and nuclear (AATS, CAD regions 1, 3 and 4) genes, 5757 bp in total, was analysed for 176 taxa using Bayesian and maximum likelihood approaches. Results indicated the Scionini are strongly monophyletic, …

Taxonomy, phylogeny and resource use of Glyptapanteles (Hymenoptera: Braconidae, Microgastrinae), genus highly diversified in the Neotropics
… of four genes is presented. The genes include mitochondrial COI (cytochrome c oxidase subunit 1) and three nuclear genes: Alpha-spectrin; long-wavelength opsin (LW Rh) and wg (wingless). All the Costa Rican material had associated COI, sequences generated partly by the collaborators in the …
