Mating Habits, Dispersal and Postglacial Range Expansion of Nigronia Serricornis (Say) (Megaloptera: Corydalidae)
… Using sequence data from a 630-base fragment of cytochrome oxidase I (COI), nested clade phylogeographical analysis (NCPA) was performed to determine the patterns of genetic diversity and the effects of post-glacial range expansion (PGRE). Haplotype diversity was significantly negatively …

Sample Collection and DNA Extraction Methods for Environmental DNA Metabarcoding in Headwater Streams
… the ribosomal small subunit 18 S (18s) and the cytochrome oxidase I (COI) gene regions. The 18s sequence data is non-reportable due to lack of sequence quality, and MoBio's PowerWater did not yield DNA suitable concentrations. CTAB and DNeasy extractions yielded successful PCR reactions and …

Metapopulation dynamics of the softshell clam, Mya arenaria
… of M. arenaria using the mitochondrial gene, cytochrome oxidase I (COI). I found minimal variability across all populations sampled, suggesting a recent population expansion in the Northwest Atlantic. Finally, I employed theoretical approaches to understand patch dynamics in a two-patch …

Phylogenetic studies of the Madagascan freshwater crabs (Potamoidea, Potamonautidae, Deckeniinae)
… a partial mitochondrial gene fragment (600 bp), cytochrome oxidase I (COI). Phylogenetic analyses, MP, ML, and BI, yielded 36 most parsimonious trees and recovered topologies with several highly-supported clades with similar topologies. The MP 50% majority-rule strict consensus tree was selected …

Range-wide Distribution and Genetic Structure of Acroneuria frisoni Stark and Brown, 1991 (Plecoptera; Perlidae): Tools for Reintroduction to Central Illinois
… reintroduction success. The mitochondrial gene Cytochrome Oxidase I (COI) was used to determine the Pleistocene glacial refugia, northward recolonization routes and the role of contemporary and ancient drainages in shaping A. frisoni genetic structure. Data suggest that there are at least three …

Aspects of the biology of Mya arenaria and Ensis spp. (Mollusca; Bivalvia) in the Irish Sea and adjacent areas
… for genetic variation using both mitochondrial (cytochrome oxidase I (COI) and 16S ribosomal RNA genes) and nuclear markers (10 microsatellite loci). Both mitochondrial CO1 and all nuclear markers showed reduced levels of variation in certain European samples, with significant differences in …

Contribution to the systematics of the genus Aphis (Hemiptera:Aphididae)
… using bootstrap Maximum Parsimony and MrBayes of cytochrome oxidase I (COI), nuclear elongation factor (EF1-∝) and primary endosymbiont Buchnera 16S (Buch 16S) were not congruent. MrBayes strongly supported most of terminal nodes of the phylogenetic trees. The phylogeny was strongly supported by …

A contribution to species delimitation and taxonomy of North American Entomobrya (Collembola: Entomobryidae)
… species, a phylogenetic analysis of the complete cytochrome oxidase I gene (COI) was performed for 11 species of North American Entomobrya, including 13 color forms representing 4 morphospecies with different levels of color pattern variation: Entomobrya assuta, E. clitellaria, E. ligata, and E. …
