In animals, Sexual dimorphism can be based on morphological characteristics or measurable characteristics. In scorpion, except a few species that have two sexual forms, there is no significant difference between males and females. In this study, 12 measurable characteristics of male and female Hottentotta saulcyi, from the Rudbar area located on the border of Lorestan, Isfahan and Chaharmahal and Bakhtiari provinces, were measured and analyzed by SPSS 16 software. Independent Sample T-test showed a significant difference between the three traits, the distance between the two shoulder lines, shoulder length, and the number of shoulder teeth between males and females. The result showed that in male, the length of the shoulder is significantly larger and also the number of shoulder teeth more than female, but the distance between the two shoulder strains in the material is larger than the male, and therefore, these traits can be in the diagnosis of both males and females.

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

The Fishes identification is one of the important studies for understanding their biology and to protect them against of environmental threats. The local fishes of each region have several values, these Fishes are part of the genetical reserves of each region that we can use in genetic research and biotechnology in the future. About the Fishes has been done sparse studies in Iran. In the present project, the fresh water fishes from Poldukhtar county of eight sampling stations were collected during the year 2013 to 2014 and after sampling of each station, Zoogeographical region recorded by the GPS, then samples were transferred to the research laboratory Arak university in the fibers full of Ice and was measured morphometrical specification of each sample and the species were identified by valid keys identification. In this study, were collected eight species belonging to the six genera of the Cyprinidae family and the species of Chondrostoma cyri، Cyprinion tenuiradius، Carassius gibelio، Capoeta damasina، Barbus grypus، Capoeta trutta، Garra rufa، Barbus barbul were identified from Poldukhtar county.

From the point of the pathogen agents' transmission, Ticks are the most important ectoparasites which cause heavy economic losses to livestock worldwide. The purpose of this study is evaluating the frequency and diversity of ticks in all age groups of both sexes in the natural habitat of domestic ruminants contains cattle, sheep and goats in Mashhad Mighan in the Markazi province. Samplings were carried out monthly (A total of 1081 ruminants from 20 flocks) from April 2015 to March 2016. Ticks were collected from all parts of the body and as well were collected from stables (animal shelters, floors and other places), a total number of 599 ticks from two families (Argasidae and Ixodidae) were collected. Ticks were identified using valid identification keys. A total numbers of 599 ticks from two families (Argasidae and Ixodidae) were collected. Ticks from the Argasidae family totaled 186 and belonged to 2 genera: Argas and Ornithodorus. The proportions of different species were as follows: Argas persicus (28.21%), A. reflexes (1%) and Ornithodorus lahorensis(1.84%). Ixodidae family collected in the area totaled 413 and belonged to 3 genera and Included 5 species: Rhipicephalus sanguines (27.71%), Rh. turanicus (24.21%), Hyalomma anatolicom(9.18%), Hy. Asiaticum(8.35%), Haemaphysalis sulcata with (0.5%), the results show that hard tick and soft tick species diversity are high in the area.

This study was conducted to identify fish larvae from the upper pelagic layer of Oman Sea، off east shore waters of Hormozgan Province during May 2011. Sampling was obliquely conducted using Bongo Bongo-net plankton sampler with 500 µ of mesh sizeby Thai Prantlay 10 Vesselle. In each station،abiotic factors (Temperature، Salinity and PH) were recorded. Upper pelagic waters of Oman Sae had less fish larvae in compare to nursery grounds like creeks and estuaries. In total 125 specimens were collected and examined. They were belonging to 8 families. Engraulidae، Mullidae and Sillaginidae were dominant families، which included 45% of total fish larvae abundance. There were 14 stations. At stations 3، 10 and 13 the biodiversity was in highest levels. The maximum abundance was 36 larvae per 10 m square of sea surface at station 12. In some stations، there was no fish larvae and in total، most of larvae were in post flexion level.

Ciliophora are the most diverse group of Protozoa that live in Brackish، Saline as well as fresh water. In Iran few works have been done on free living Ciliophora. In the present study we consider the density of free living Ciliophora for a period of one year from April 2006 to March 2007 in Ghareh Kahriz River. In the present study، the fluctuation of physico – chemical parameters (air and water temperature، dissolved oxygen، carbon dioxide، pH، total hardness، and total solids)، in relation to the population density of free living ciliates from three sampling sites in the length of Ghareh Kahriz river were considered. Maximum population density of free living Ciliophora observed in summer and autumn and in the sampling sites of 2 and 3، respectively. Paramecium caudatum and Litonotus fasciola showed، respectively، the maximum and minimum population density during the period of study. The high population density of free living ciliophora is due to the moderate water temperature، pH، dissolved oxygen as well as more food concentration due to the entrance of city west water drainage in summer and autumn and sampling stations 2 and 3. High water current، cold weather، and low food concentration in winter and spring might be responsible for the population density fluctuations in the present study.

Main goal of this investigation were verification of gene's behavior which located on RNO15 with allelic imbalance during Endometrium cancer development. BDII/Han females were crossed to males from two other inbred rat strains known to have low incidence of EAC (BN/Han and SPRD-Cu3/Han). To generate F2 rats the F1 animals were intercrossed. In addition, backcross populations were generated by crossing male F1 rats to female BDII rats. In order to characterize these tumor-specific genetic aberrations in greater detail, we applied molecular cytogenetic methods (FISH, chromosome painting) to 18 rat endometrial adenocarcinoma (EAC) cell cultures. Analysis in the tumors by FISH analysis showed the presence of small regions of amplifications. These changes were cryptic so that they occurred inside cytogenetically normal-looking chromosomes. We detected rather specific chromosome aberrations (translocations, deletions, amplifications) often leading to copy number changes in small DNA segments (gains, losses).

The cuckoo wasps (Hymenoptera, Chrysididae) having interesting metallic coloration are interesting family of wasps that are not studied sufficiently in Iran. This family is reviewed in Iran, based on recently collected materials from north- west of Iran and available literature.
