Identification and Classification of macrobenthos of Seymare dam Lake in Ilam province performed for one year from farvardin 1395 to esfand 1395. At a distance of approximately 60 Km, 5 stations were determined and seasonally isolated from the species. Sampling was carried out using grab van veer model with a surface coating 0.625 microns per station. Collected samples were fixed by 70 % ethanol and counted in the laboratory. In this study, 11 species, 25 genera and 22 families of benthic organisms were identified, and most of which included water-insect larvae. And total number of identified benthos included 189. The maximum frequency at 5 stations belong to Chironomidae family. At the same time, by sampling the Benthos, some physico-chemical factors such as water temperature, salinity, NO2, NO3, NH3, PO4, CO2, BOD5, DO and PH were measured at the stations. Results showed significant changes on BOD5, DO, NO2, NO3, PO4 and PH (p<0.05). But changes in other parameters were not significant (p>0.05).The results of biological indicators showed that the highest variation in winter and most species dominance was observed in autumn and spring.

 The study of reptile to protect them is a high priority for conservation of biodiversity of each country. Iran is located in South West Asia has special ecological zones and diverse habitats. Iran Ecological habitats contains more than 200 species of reptiles that their biodiversity and ecological values is unknown. Kermanshah has rich fune of reptiles because ithas suitable geographical location weather conditions and habitats. The purpose of this study is to evaluate Sonqorlizards fune by analyzing the morphological and morphometrical characteristics and use of valid identification keys. The study was conducted from April 2014 to August 2015, totally, 163 lizards from 6 different station of Sonqor (North East of Kermanshah province) were collected and transferred to the Zoology laboratory. Photos were taken from the lived samples, then the samples was put up in 10% formalin. The results showed that 10 species of lizard belonging to 10 genera and 6 families living in these areas are:Ophisops elegans, Luadakia nupta,Paradakia caucasica, Cyrtopodian scarbum, Trachylepis aurata, Trapelus lessonae, Apathya Cappadocia.In this study index of any species were measured by using the Shannon-Wiener, Simpson index, biological levels of diversity and dispersion.Finally dominant species (Ophisopselegans) karyotype obtained by using metaphase plates. Karyotype result showed that chromosome number of this species is 2n = 30.

The study of reptiles and measures to protect them is a high priority for conservation of biodiversity of any country. Iran is located in South West Asia has special ecological zones and diverse habitats contains more than 200 species of reptiles that is unknown their biodiversity and ecological values. Khouzestan has rich fune of reptiles because of is located in suitable geographical location ،weather conditions and habitates .The purpose of this study is to evaluate Izeh and Baghmalek lizards fune by analyzing the morphological characteristics and use of valid identification keys. The study was conducted from April to October 2014, in this time was collected 105 samples Lizards from 6 different stations Izeh and Baghmlk (North Eastern of Khuzestan province) and transferred to the Zoology laboratory.There were taken photos and peripheral slides from the lived samples ,then the samples was put up in 10% formalin. The results showed that 10 species of lizards belonging to 10 genera and 6 families living in these areas are: Laudakia nupta ,Trapelus agilis , Eublepharis angramainyn , Mesalina watsonana , Ophisops elegans , Mabuya aurata septemataeniatay , Varanus griseus , Hemidactylus persicus , Cyrtopodiom scabrum , Asaccus elisae. In this study index of any species were measured by using the Shannon-Wiener, Simpson indices and examined biological levels of diversity and dispersion of lizards , finally dominant species (Mabuya aurata septemataeniatay ) karyotype obtained using metaphase plates and karyotype result show that chromosome number of this species is 2n = 28.
 

The most primitive and ectothermic vertebrates are xerophyte amphibians. Most of them have a external fertilization and They are considered as bioindicators. Modern amphibians are divided into three orders . Amphibians are 7113 species , which 6274 species of them belong to the tailless amphibians (Anura). The purpose of this study is to identify and investigate karyological amphibian(Anura) species of Aleshtar city in the Lorestan Province. Aleshtar city is at 48 degrees &15 minutes east longitude and 31 degrees & 51 minutes north latitude.In this study 3 stations was selected in the three part Aleshtar city. 160 live frogs were hunted and they were transferred to the lab. Species identifying based on morphological and karyological features showed that hunted frogs belong to pelophylax ridibundus with a chromosome number 2n=26.Frequency of both sexes showed that males are more than females in all stations. Comparison of morphometric parameters in three stations showed that there is no difference between 4 parameter of leg length , tibia length, the size of the tympanic membrane and weight (p≤0/05). Also,the effect of sex on four morphometric parameters at each station were analyzed by T-test analysis.The results showed that the Ahangaran and Chale station only between the parameters tympanic membrane parameter and sex is no significant relation and in the other parameters there is a significant relation. There is a significant difference between all morphometric parameters and sex at Mansoor Abad station (p≤0/05).
