... to alignment, the raw fluorogram sequences were visually inspected and cleaned up using Chromas LITE Version 2.1.1. Sequences were aligned against 7 16S rDNA and 16 D- Loop region corresponding sequences of P. antarctica retrieved from the nucleotide database NCBI (Fig. 3, see Table 1 for GenBank accession numbers). Alignment was then performed by MUSCLE (http://www.ebi.ac.uk/Tools/msa/muscle/) using MEGA 6.06 ( Tamura et al. 2013). Three closely related notothenioids Aethotaxis mitopteryx, Dissostichus mawsoni and Dissostichus eleginoides (Near et al. 2012) were included as outgroups (Fig. 3, see Table ...

The proportion of nucleotide positions at which two sequences differed represented by the p-distance was used to calculate genetic distance in MEGA. Based on these distances, a neighbour-joining tree was drawn using the Kimura 2-parameter substitution model, with tree robustness confirmed by ...

Mitochondria are an essential cell organelle for all living cells, if they are eliminated from the cell that means the cell has undergone terminal differentiation. It works like sub-kingdom in the cell; in addition to provide energy to the cell it has its own gasket of synthetic machinery. In each individual it is contributed by mother. If there is...

Reproduction is a key step of a species life history and includes a suite of strategies and tactics enacted to allow the maximization of reproductively active offspring in relation to available energy and parental life expectancy. Gender system, oogenesis pattern, maturation schedule, shifts in habitat utilization, spawning seasonality, mating behavior, and fertilization pattern are among the traits involved in the process of species adaptive optimization of reproduction.
In this frame, here we review the reproductive traits of the Antarctic silverfish (Pleuragramma antarctica) based on the available macroscopic and histological data. Then, we will step forward by focusing on two aspects of this species’ reproduction: (i) skipped spawning; (ii) potential location of reproduction sites along the Antarctic coasts.
