Mitochondrial DNA sequence variation in North Atlantic long-finned pilot whales, Globicephala melas
I sequenced mitochondrial DNA (mtDNA) from 59 long-finned pilot whales (Globicephala melas) that stranded on the coasts of Cape Cod, Newfoundland, Nova Scotia, Scotland, and England or were caught by commercial fisheries operating in the western North Atlantic, to determine if there is more than …

Mitochondrial DNA Sequence Variation in Populations of the Nine-Banded Armadillo (Dasypus novemcinctus)
… Arkansas and central Texas). A 233 basepair sequence of the D-loop region of mitochondrial DNA was sequenced in individuals from each population. Individuals and populations were compared to assess relatedness among populations and individuals. Higher sequence diversity was detected in the …

Comparative Mitochondrial DNA Sequence Diversity in Isolated and Open Populations of Southern Flying Squirrels
… A 367 nucleotide hypervariable region of mitochondrial DNA was sequenced in individuals from each population. Individuals and populations were compared to assess relatedness. Higher sequence diversity was detected in the open and island populations. One island individual shared characters …

Evolution of the African Tigerfish (Genus Hydrocynus) : phylogeographic insights into drainage evolution
… phylogeographic methods. In this study, the mitochondrial DNA sequence diversity of the characiform genus, Hydrocynus, which is widespread across tropical Africa, is reconstructed using a phylogenetic framework and divergences are dated using the cytochrome b (cyt) region.

Experimental and Population Genetic Evidence of Host Race Formation in a Specialized Lycaenid Butterfly
… Combined with the previous experimental results, mitochondrial DNA sequence and AFLP data indicate varying levels of differentiation among host associations, and identify a role for both isolation in allopatry as well as ecological factors in limiting gene exchange. The experimental assessment of …

Molecular Systematics & Evolution of the CTENOSAURA HEMILOPHA Complex (SQUAMATA: IGUANIDAE)
… patterns within <em>C. hemilopha</em> mitochondrial DNA sequences and reconstruct species and area relationships among the various taxa. The molecular evolution of the <em>C. hemilopha</em> complex is analyzed using 1109 base pairs of mitochondrial DNA sequence from the cytochrome …

Significant Population Structure and Little Connectivity in South African Rocky Shore Species: Implications for the Conservation of Regional Marine Biodiversity
… along the South African coast we analyzed mitochondrial DNA sequence data for 10 sessile rocky-shore species and one reef-fish that represent three distinct life history strategies. We find that the distribution of genetic diversity across the South African coastline closely mirrors the …

Genetic Relationships Of Wild Pigs (sus Scrofa) In The United States: Geographic Origins And Genotypic Distribution Of The Species With Implications For Management
… I utilized an array of molecular markers (mitochondrial DNA sequence, nuclear microsatellites, and nuclear single nucleotide polymorphisms) to evaluate both the evolutionary history of introduced pigs and gene flow between populations indicative of dispersal pathways. </p> <p> Mitochondrial …

The Molecular Systematics of the Side-blotched Lizards (IGUANIA: PHRYNOSOMATIDAE: UTA)
… lizards is analyzed using 1132 base pairs of mitochondrial DNA sequence from the cytochrome b and cytochrome oxidase III genes. Samples come from 98 'individuals from 50 islands in the Gulf of California and Pacific Ocean and 48 adjacent populations from Baja California Sur, Baja California, …

The Evolutionary biology and taxonomic review of Zambian riverine haplochromine cichlids
… complex. Phylogenetic studies were based on mitochondrial DNA sequence analysis while the taxonomic studies were based on principal component analysis (PCA) of morphological characters. The results indicate that the Zambian riverine haplochromines share a common ancestor, which is likely to …

Population genetic relationships in the roseate tern: globally, regionally and locally
… study, two kinds of genetic marker, ND2 and ND6 mitochondrial DNA sequences and microsatellite genotyping, were used to investigate the historical and contemporary relationships among roseate tern breeding colonies. I used samples from breeding colonies in Australia, Japan, Seychelles, South …

Assessment of the Endangered Species <i>Podarcis carbonelli</i> on a Microgeographic Scale: A Molecular, Morphological and Physiological Approach
… morphological and physiological approach. We sequenced the 12S RNA, the mtDNA Control Region and the 7th intron of the !-fibrinogen gene and determined genetic diversity values as well as several parameters of population structure and differentiation. Individuals from these populations were …
