Phylogeography and ecology of New Zealand freshwater Amphipoda (Paracalliope, Paraleptamphopus, and Phreatogammarus)
… the phylogeographic patterns using both mtDNA (CO1) and nuclear DNA (28S) showed that a number of distinct genetic lineages exist, with CO1 revealing 21 haplotypes with genetic distance of over 20%. Using a molecular clock rate of 2.4%, most haplotypes diverged approximately 8-12 million years …

Tracking environmental trends in the Great Bay Estuarine System: An examination of water quality and nuisance macroalgal blooms
… measure was 1%. Sequencing of ITS2, rbcL, and CO1 revealed the presence of previously undetected Ulva and Gracilaria species, including Gracilaria vermiculophylla (Ohmi) Papenfuss, an invasive species of Asian origin. Gracilaria vermiculophylla has surpassed G. tikvahiae as the dominant …

Characterizing Cystoisospora canis as a Model of Apicomplexan Tissue Cyst Formation and Reactivation
… C. canis genetically using ITS1 and CO1 to build phylogenetic trees and found C. canis was most similar to C. ohioensis-like with ITS1 and more similar to T. gondii than any other coccidia using ITS1 and CO1. We identified genes and proteins involved with virulence, cyst wall …

Taxonomic, ecological and quantitative examination of chewing lice (Insecta: Phthiraptera) on Canada geese (Branta canadensis) and mallards (Anas platyrhynchos) in Manitoba, Canada
… mean intensity was 42.0 lice per bird. Based on CO1, A. dentatus and Anatoecus icterodes were synonymised as A. dentatus. Anatoecus was found exclusively on the head, Anaticola was found predominantly on the wings, Ciconiphilus, Holomenopon and Ornithobius were observed in several body regions …

High-Performance Low-Cost Catalysts for Water Electrolysis: A Computational and Experimental Study
… atomically dispersed catalysts (ADCs) of Fe1 and Co1 supported on SnNiOx. Electrochemical measurements demonstrated that Fe1 and Co1 ADCs prepared with H2 plasma significantly enhanced OER activity by reducing charge-transfer resistance. The best catalyst, Fe1Co1/SnNiOx prepared with H2 plasma, …

Authentication of Species in Bison Products Using Molecular Methods
… of the cytochrome <em>c </em>oxidase subunit 1 (CO1) gene is a commonly used method to test for meat species mislabeling. However, due to historical hybridization between the American bison and domestic cattle, additional testing is required to confirm species. The objective of this study was to …

The effect of hybridization on metabolism and hypoxia tolerance in sunfish
… differences in complex IV catalytic subunits (CO1, CO2, CO3) were minor, however the mtDNA-encoded subunit of complex III (cytochrome b) showed 8 differences between bluegill and pumpkinseed, several of which could have structural consequences to the multimeric enzyme and contribute to the …

Molecular Phylogenetic Analysis of Argynnis Fabricius (1807) including North American Speyeria Scudder (1872)
… within Argynnis , using one mitochondrial (CO1) and four nuclear genes (EF1?, WG, GAPDH, and RPS5). The results indicate that North American Speyeria is a monophyletic group, but that Palearctic Argynnis is paraphyletic. Three major lineages are identified within Argynnis sensu lato : two …

Determination of the Presence of <i>Rickettsia</i> Spp. and <i>Borrelia</i> Spp. Carried by Tortoise Ticks from Madagascar
… PCR that amplified tick cytochrome oxidase (CO1) and tick 12S rRNA genes. Ticks were screened via a real-time polymerase chain reaction assay for the presence of <em>Rickettsia</em> spp. and Borrelia spp., amplifying the rickettsial 17 kDA and <em>Borrelia</em> 16S rRNA gene, respectively. …

Taxonomy, Biogeography and Pest Status of Marmara sp. in Northern Mexico and California Citrus Production
… at UC Riverside, which concentrated on the CO1 region of mitochondrial DNA, reported significant differences in genetics based on the geographic origins of specimens (Vickerman and Stouthammer 2006). Geographically, the genetic distribution described in the 2006 study does not coincide with …
