Ticks are scattered all over the world as aquatic and terrestrial groups. Livestock ticks are obligate parasites that target small and large livestock. In this study, 5 stations in the Kojur region were selected and livestock were sampled. The tick samples collected in Eppendorf bottles containing 70% ethanol and 5% glycerin were transferred to the laboratory of Arak University. They were identified with the help of valid identification keys of their genus and species. In this research, 173 livestock including 95 cattle and 78 sheep were studied, of which 139 were infected with ticks. A total of 572 ticks (420 ticks belonging to the hard tick family and 152 ticks belonging to the soft tick family) were collected. From the Ixodidae family, six species belonging to the three genera Hyalomma, Haemaphysalis, and Rhipicephalus, including two species Hy. anatolicum and Hy. asiaticum, two species of Ha. Punctate and Ha. sulcata, and two species R. Sanguineus and R. Turanicus were identified. In the family Argasidae 2 genera and 3 species were identified, which genera include Argas and Ornithodoros. In this family, Argas species were completely distinguished from Ornitodoros species. From the Argas genus, A. persicus and A. reflexus species and from Ornithodoros genus, O. lahorensis species have been isolated and identified.

Natural history museums are one of the most important types of museums in the world, serving as an effective and engaging means for promoting science, connecting the community with universities, and providing essential infrastructure for education and research. However, they fulfill these roles best when they are up to date. Therefore, in this research, I updated the labels of bird specimens of natural history museum and technology of Shiraz University to increase the efficiency of the museum in terms of educational duties. All specimens were examined based on morphological traits and identified to the species level using valid references. Errors in species identification were corrected, taxonomic status for each species was updated, and a database was prepared. New labels for the specimens were designed, and more detailed data is now available to visitors through a QR code scan on the specimen’s label. The results showed that the bird collection contains about 350 specimens belonging to 147 species, 121 genera, 53 families, and 24 orders. The highest species diversity is found in the order Passeriformes with 32 species, followed by the order Charadriiformes with 17 species, and after that, the orders Accipitriformes, Anseriformes, and Galliformes, each with 15 species. The results indicate that the classification of 31 species has changed at the order level, eight species at the family level, and six species at the genus level. Consequently, 45 taxonomic changes were updated in this study. Finally, some suggestions were made for increasing efficiency and attracting more visitors.

So far, 13 species were recently recognized in the Iranian basins. In the present study the variation among A. eichwaldii, A. namaki, A. idignensis, and A. nicolausi, A. qanati A. petrubanarescui has been investigated from morphological and molecular approaches. To study the morphological characteristic, 144 specimens of these six species were used, on which 22 morphometrics were measured. Nine meristics characteristics were counted. Analysis of variance (ANOVA), discriminant analysis, and principal component analysis was performed. In the molecular studies, sequences of the mitochondrial gene, cytochrome b from six species were sequenced and analyzed. The morphological results of the data showed a high similarity among species, but could separate A. nicolausi and A. idignensis according to the PC1. Also A. idignensis and A. petrubanarescui are more similar based on the PC2. Moreover, based on meristic characteristics which were relatively similar, again A. nicolausi and A. idignensis could be separated by the first component. The phylogenetic analysis using Maximum Likelihood (ML) and Maximum-Parsimony (MP) methods supported the monophyletic status of the six species, suggesting their status as different species. The results of the molecular analysis showed that A. eichwaldii and A. petrubanarescui have the most similarity (about 99%) and the A. idignensis has the maximum difference (about 85%) with the other species. These results justify the results of morphometric analysis.

Abstract Precise identifying of a Barbus fish species and the hybrids is very important because these fishes are large freshwaters fishes of Iran and the stock of them are going to vanished. In 2000 the Barbus species of Iran was revised at CMN and from that time all document of these species were reviewed, this is a part of this studies. In 1842 Heckel described Lebeobarbus kotschyi and named it in respect to Theodor Kotschyi. During the time this name has changed to Barbus kotschyi. Barbus kotschyi (Heckle, 1843) was synonymized with Barbus grypus Heckle, 1843 by several authors. The samples was examined In my projects the morphological differences between these two related species is enough to separate them, but for conceding them as two identical species more recherché has to be done and more samples must be collected. In this paper the more outstanding features and differences between these two species are outlined. The difference between this species and Barbus grypus, to which it is deceptively similar, lies mainly in the relative head length, the mouth, and the fleshy lobe below the symphysis of the lower jaw. In querying among 2000 professional angler, they states that have caught this fish and named it as a night touring fish.

Abstract Mitochondrial genes important tool in various studies in the fields of animal evolution, is phylogeography and phylogenetic. Based on the analysis carried out by sequencing mitochondrial Cytochrome b gene, five samples of Iranian jerboa and two Hotson's Jerboa from the Mirabad plains and Chupanan in Naein, Isfahan Province, respectively, were sampled, it was found that the divergence between the two groups, but this degree of intraspecific divergence between the two species is not enough to lead to the divergence. However, concludes that different habitat conditions, different diet and feeding behavior induced evolutionary divergence and this process in the future, especially in the absence of gene flow between populations may lead to speciation. Extensive studies and more accurate than relying on other molecular markers such as microsatellites and nDNA is suggested.
