Tick transmit infective agents to humans and animals, and carriers of parasitic and viral diseases such as the Crimean Congo bleeding fever. The purpose of this study was to identify valuable morphobiometric characters for differentiation of Ixodida order using morphobiometric methods. For this purpose, a total of 186 ticks were identified from the Argasidae family belonging to the two genera of Argas and Ornithodoros, including the species Argas persicus, A. reflexus and Ornithodoros Lahorensis. 413 ticks are from the Ixodidae family, which belongs to 3 genera and 5 species including Rhipicephalus sanguineus, R. turanicus, Hyalomma anatolicum, H. asiaticum, Haemaphysalis sulcata and were identified using several valid identification keys. The study of species diversity and frequency of cattle, sheep and goats in all age groups and both sexes were done in ruminant including cattle, sheep and goats. To this end, 20 stations were selected in the Mashhad Meyghan area and sampling was carried out monthly and during one year from April to March 2017. A total of 18 morphobiometric parameters were determined using calibrated stereomicroscope. The data were analyzed by PCA method and analyzed using SPSS software (version 16), and analyzed by UPGMA, PCO and PCA methods using MVSP software, then shrubs and the corresponding charts were drawn. In PCA analysis, a total of 4 components of morphobiometric traits were obtained, which explained 91% of the total variance. One-way ANOVA showed a significant difference between between most of the traits.

Abstract The Mollusca are smooth skin and without split and with a variety of morphology that often isolated in a calcareous shell. In during year 2010 has been conducted, in the surrounding Dadghan village from Tafresh County of Markazi Province, and the entire extended layers in this region were found and the sampling operation has been carried out in perpendicular direction to these layers. then sampling stations Zoogeographical region recorded by the GPS and samples was transferred to the biological laboratory of Arak University, finally, the samples was identified by valid resources identification. In the present study, studied fossil belongs to genus Pectin from Pectenidae family. The genus of Bivalvia class, the Bivalvia class is mollusca that live in freshwater and marine. Some of the main characteristics of this genus are: external shell of circular, lateral symmetry in one valve and inequality with the other valve, presence of a singular muscle, and superficial frills are observed on the shell in the form of radial and thick lines. The genus of Pectin are new record for Markazi Province
