Molecular Taxonomy And Phylogenetic Analysis Of Dove And Pigeon Species (Aves: Columbidae) Of Pakistan, Based On Coi Region Of Mitochondrial Dna, Hina Rafiq, Fakhar -I-Abbas, Fakhra Nazir, Fida Muhammad Khan

Journal of Bioresource Management

Doves and Pigeons are the members of living family Columbidae (Order: Columbiformes) having a wide range of taxonomic diversity and geographic distribution. Seven species with one sample each of family Columbidae were collected via random sampling from different districts of Pakistan to carry out this study. The targeted gene region was sequenced and identified by using BLAST tool at National Center for Biotechnology Information (NCBI). CLUSTALW was used for sequence alignment and MEGA6 for reconstruction of phylogenetic trees to predict the effective ancestry of different Columbidae species. The following phylogenetic trees were obtained i.e. Maximum Likelihood tree, Neighborhood joining tree, …

Genetic Diversity Of Codling Moth Cydia Pomonella L. (Lepidoptera: Tortricidae)Populations In Turkey, Akin Kuyulu, Hani̇fe Genç

Turkish Journal of Zoology

The codling moth (Cydia pomonella L., Lepidoptera: Tortricidae) is a well-known pest worldwide and was first reported in 1952 in Turkey. It is traditionally controlled with several pesticide applications during each apple production season. The genetic diversity of codling moths was investigated in this study, based on the partial mitochondrial cytochrome oxidase subunite I gene. Twenty-two haplotypes from 9 populations were studied. The results showed an average haplotype and nucleotide diversity of 0.835 and 0.571, respectively. Phylogenetic analyses were indicated for 2 major clades using the maximum likelihood method. Median Joining Network analysis revealed that the 2 major clades are …

First Record Of The Atlantic Blue Crab Callinectes Sapidus (Crustacea: Brachyura: Portunidae) In The Segura River Mouth (Spain, Southwestern Mediterranean Sea), Mercedes Gonzalez-Wanguemert, Juan Antonio Pujol

Turkish Journal of Zoology

A single male individual of Callinectes sapidus (Crustacea, Decapoda, Portunidae) was collected on 6 December 2014 in the Segura River mouth in southeastern Spain. Information on collection site, DNA barcoding, and its present distribution and dispersal strategies are provided.

Relative Abundances Of The Recently Introduced Barnacles, Megabalanus Coccopoma And An Unidentified Species Of Megabalanus, In The Southeastern U.S., Jennifer L. Tyson

Honors College Theses

ABSTRACT

Megabalanus coccopoma is a prominent invasive species off the coast of Georgia. Recently, among collected samples thought to be M. coccopoma, several individuals of an unidentified species of barnacle were found. The species has been identified as a Megabalanus species, but is still unidentified to the species level. Species identification is difficult due to morphological variation, inconsistent taxonomic keys, and unknown origin. In this study I developed a method to accurately distinguish M. coccopoma from the unidentified Megabalanus sp. using sequence differences in the mitochondrial Cytochrome Oxidase I (COI) gene. This study will provide an accurate estimate of …

Dna Barcoding Distinguishes Pest Species Of The Black Fly Genus Cnephia (Diptera: Simuliidae), I. M. Confitti, K. P. Pruess, A. Cywinska, T. O. Powers, D. C. Currie

Department of Entomology: Faculty Publications

Accurate species identification is essential for cost-effective pest control strategies. We tested the utility of COI barcodes for identifying members of the black fly genus Cnephia Enderlein (Diptera: Simuliidae). Our efforts focus on four Nearctic Cnephia species—Cnephia dacotensis (Dyar & Shannon), Cnephia eremities Shewell, Cnephia ornithophilia (Davies, Peterson & Wood), and Cnephia pecuarum (Riley)—the latter two being current or potential targets of biological control programs. We also analyzed one Palearctic species, Cnephia pallipes (Fries). Although Cnephia adults can be identified anatomically to species, control programs target the larval stage, which is difficult or impossible to distinguish morphologically. By using …

A Re-Examination Of Diplectrona Modesta Banks 1908 (Trichoptera: Hydropsychidae) Using Morphological And Molecular Techniques, Lauren Harvey

All Theses

Diplectrona modesta Banks 1908 (Trichoptera: Hydropsychidae) is a common inhabitant of streams across eastern North America. This species is well known and used often in biomonitoring studies. Experts in the field have long noted the morphological variation in larval head color and patterns as well as the species presence in many different types of habitats, such as springs, seeps, streams, and some small rivers. This study examines the species both morphologically and molecularly using mitochondrial and nuclear genes in order to determine if the species is a complex of several species or one highly variable species. DNA sequencing using the …

Molecular Identification, Phylogeny And Geographic Distribution Of Brazilian Mangrove Oysters (Crassostrea), Aline Grasielle Costa De Melo, Kimberly S. Reece

VIMS Articles

Oysters (Ostreidae) manifest a high degree of phenotypic plasticity, whereby morphology is of limited value for species identification and taxonomy. By using molecular data, the aim was to genetically characterize the species of Crassostrea occurring along the Brazilian coast, and phylogenetically relate these to other Crassostrea from different parts of the world. Sequencing of the partial cytochrome oxidase c subunit I gene (COI), revealed a total of three species of Crassostrea at 16 locations along the Brazilian coast. C. gasar was found from Curuca (Para state) to Santos (Sao Paulo state), and C. rhizophorae from Fortim (Ceara state) to Florianopolis …
