Channa are the freshwater and important food fish species in Pakistan belonging to family Channidae. However, identification and phylogenetic analysis based on molecular tools of these species in Pakistan was not well known. Herein, the current investigation was conceptualized, which dealt with mitochondrial DNA sequences from three geographically distinct populations of this species from Pakistan’s water system. DNA from fin tissues was extracted. COI region of mtDNA was amplified using universal primers for fish. PCR products were sequenced. Phylogenetic analysis conducted in the present study, i.e. neighbor-joining (NJ) cladogram, maximum likelihood, K2P genetic divergence and histogram suggests that the studied …

Virginia Journal of Science
Life-history aspects of Moxostoma cervinum(Blacktip Jumprock) were identified using specimens from recent collections and the Roanoke College Ichthyological Collection. The largest specimen examined was a female 161.27 mm SL and 66 months of age. Spawning appears to occur in May, with a mean of 2477.6 oocytes (SD = 2825.3) up to 1.54 mm diameter in gravid females. Sexual maturity appears to occur by 1-2 years of age in males and 2-3 years of age in females. Male to female ratio was not significantly different from 1:1. Chironomidae composed the bulk of the diet; while detritus, Trichoptera, Ephemeroptera, and Acari …

The genus Crypthecodinium (Dinophyceae) currently consists of only one species: C. cohnii, a heterotrophic marine dinoflagellate widely known able to produce prolific amount of DHA. However, previous studies revealed that there are morphological and genetic differences among Crypthedodinium cohnii-like strains, indicating the potential of undiscovered diversity of this dinoflagellate. Attempts of isolating heterotrophic marine dinoflagellate strains were made from submerged mangrove leaves and seaweed. A total of nine strains were established, cultured and maintained using seawater-based GTY medium for taxonomic identification and phylogenetic analyses based on SSU, ITS1, 5.8S, ITS2 and LSU rDNA. Morphological observation revealed all strains shared similar …

Coral-inhabiting gall crabs are either obligate symbionts or parasitic associates with their host corals. They form a variety of galls/pits inside the skeleton of living corals. Nine genera of gall crabs on several scleractinian corals were used to test the hypothesis that galls vary among cryptochirid genera. Phylogenetic and morphometric observations were combined to analyze the possible evolutionary significance of gall construction. A high degree of conservation of gall shapes was observed in relation to the gall crabs’ phylogeny. Gall/pit morphology and fidelity was studied in each of the different species of gall crabs. In addition, the correlation analysis results …
