Exact identification of an insect sample is usually the first essential step in a forensic entomological analysis. However, the morphological similarity of beetles in the level of species usually poses a challenge for forensic scientists within their routine work. As a supplementary to traditional morphological method, molecular genetics identification turns out to be simple and time-saving. A ...

The conventional taxonomy on sea cucumbers is challenging due to their morphological complexity. Molecular investigation of the class Holothuroidea was initiated for further clarity regarding systematics and this class. A molecular phylogeny constructed by using maximum likelihood methods, unveiled variation in existing taxonomic classification, which largely based morphology calcareous parts. ...

The taxonomy of cyanobacteria has been substantially modified in the last few decades, particularly after application of modern ultra structural and molecular methods. The present research, therefore, aimed to investigate, through a polyphasic approach, the differences in morphological and genotypic features of two cyanobacteria strains isolated from different agricultural and freshwaters areas...

Species identification is a difficult task, ranging from the definition of the species concept itself to the definition of the threshold for speciation. DNA Barcode technology uses a fragment of the Cytochrome Oxidase I (COI) gene as a molecular tool that many studies have already validated as a tool for species identification. DNA barcode sequences for COI were generated and analyzed from 805 ...

background : haemonchosis has a negative effect on the farming industry throughout the world, especially in the tropic and sub-tropic countries. the present study was carried out to differentiate haemonchus species from its main hosts in iran, including sheep, goat and camel.   methods: the identification took place based on the morphometrics of the spic-ules and molecular characters. two hundr...

A non-pigmented and asporogenic fungal strain without taxonomically useful characteristics was isolated from sputum of a patient with chronic bronchitis. Although the taxonomic position could not be determined based on traditional morphological criteria, the fungus was identified as an Aspergillus fumigatus mutant strain by molecular techniques including ITS sequence analysis and PCR identifica...
