Despite the large global biodiversity conservation efforts, there are many threats including land-use/cover changes, climate change, habitat fragmentation, and anthropogenic activities that can increase the potential vulnerability of a natural protected area. The challenge for conservation managers is to ensure the long-term sustainability of an area by preserving its ecological values against natural and human pressures. This research proposes an integrated use of GIS–based Analytic Hierarchy Process (AHP) for vulnerability assessment of Abbasabad Protected area, Eastern part of Isfahan province, to foster conservation strategy in the study area. For this purpose, after intensive literature review, and field visit the most important criteria were identified and using Analytic Hierarchy Process (AHP), problem solving structure was formed, and then the database contains criteria layers was prepared. The criteria were divided into two main groups including 1) biophysical criteria, and 2) disturbances, and then criteria importance was obtained with poll from experts. The data analyses have been done by Expert Choice software. The results showed that disturbance criteria are more important comparing biophysical criteria for determining priority areas for conservation planning in the study area. The final map can be used to assess habitat condition, Vulnerability to environmental pressures and identifying areas with high risk. Based on the result, approximately 17 percent of the study area that is located in the North and East part of the study area is the most vulnerable and 15 percent of the area that is located in the central part, are less vulnerable.

One of the most important environmental pollutants is heavy metals that have accumulated in the tissues of organisms and at low levels can cause poisoning. The present study aims to measuring the concentration of heavy metals in different tissues of Common Mouse as a bioindicator species in Aran and Bidgol city. Thirteen specimens of Common Mouse were collected from two agricultural area of Majidabad and Beheshtieh located in Aran and Bidgol in summer 2013. Concentrations of metals in tissues of this species were measured by ICP-OES. Mean concentration of metals in liver, kidney and muscle was obtained respectively for Zinc 135.06, 87.97 and 61.80 µg/g dw, for copper was 21.59, 18.56 and 7.33 µg/g dw, for lead was 4.26, 6.80 and 2.39 µg/g dw, and for cadmium was 4.19, 7.25 and 4.97 µg/g dw. The results of one-way analysis of variance showed that accumulation of zinc in liver and lead in kidney were significantly higher than other tissues (p< 0.05). Also accumulation of copper in muscle and cadmium in liver were significantly lower than other tissues (p< 0.05). In general, higher concentrations showed in males specimens than females and also specimens collected from Majid Abad region than Beheshtieh region. In this way, the concentrations of lead and cadmium in liver of male specimens were significantly higher than females (p< 0.05). Lead concentrations in the liver and the concentration of cadmium in the liver and kidney of specimens collected from Majid Abad were significantly higher than Beheshtieh region (p< 0.05). The sexual differences in metals concentrations could be due to female reproduction and lactation.

The creation of protected areas as natural reserves to prevent loss of biodiversity in the world is a key action. In the meantime, determination of the biological hotspots is considered as the most effective way to protect species. Among vertebrates, birds are indicator species to determine hotspot areas. This study was conducted to determine the hotspots bird area in the Naqadeh township. This study was conducted during 2010 and 2012, to collecting presence points of birds and analyzed using geographic information systems (GIS). In total, 145 bird species were identified in this township. The results of this study showed that the highest numerical values of the pixels were belonging to ecotone areas in the Naqadeh township. Also Aq-Qala and Solduz Wetlands, farmlands and Gadar River were identified as an important for biodiversity hotspots in this township. In total, three conservative hotspots with an area of respectively 4828, 1941 and 554 ha were identified for birds in the Naqadeh township, a total including 14% of the township's areas. According to the richness of the birds in the Naqadeh township, it is essential to find ways to manage and protect these patches. Determined patches overlapped 15% with managed area and 85% with free zones. According to high bird richness in this township, it is also recommended that similar studies be done in large scale to identify hotspots areas of birds in the country.

The current study is aimed to determine diet and food preference of the graylag goose during the wintering season in wet Grassland of Bojagh National Park. Firstly, in order to identify the diet, droppings were gathered done during the first months of winter 2012 and 2013. Simultaneously, the scheme of quadrating was performed using 1 square meter plots with a distance of 50 meters between adjacent plots, located along three transects to identify the wet grassland vegetation. 53 dropping sample was collected Plants to determine preferable foods and it was compared with plants located in grassland after building their tissue epidermal. Then percentage of Relative Frequency of occurrence, Percentage occurrence and relative volume percentage for each food item in dropping samples was calculated, and also food preference was measured using Manly’s alpha. Results of graylag’s diet showed that the plant of Germaine family (Poaceae) is located at first stage of the species’s diet. After that, Medicago spp of family with the amount of %20/94 Relative Frequency of occurrence and %58/49 percentage of occurrence and %7.23 relative volume and Runculaceae with the amount of %12/16 Relative Frequency of occurrence and %33/96 percentage of occurrence and %3/33 relative volume respectively devoted the most amount of graylag species’s diet. On the other hand, the results of food preference showed that three food items preferable to the species were Poaceae, Eryngium caucasicum and with 0.237, 0.216 and 0.17 manly’s alpha respectively. The food items almost include plants with hemicryptophyte and therophyte life forms. Therefore, adapting management approaches such as maintenance of vegetation cover in the early stage of succession and integrated management of livestock grazing in order to maintain vegetation diversity of wet grasslands from in the invasion of undesirable tall plants in order to keep the guild of this migratory bird in bojagh national park are recommended.

The family Sciomyzidae belongs to the order Diptera. The larvae of snail-killing flies feed on aquatic snails. These snails host a large group of human and animal parasites such as Fasciola and Schistosoma. Fighting these parasites takes place through different methods such health trainings, environmental rehabilitation, treatment of patients, and fighting the intermediary host snails. Hence, these flies play an important role in biological controls. In this study, the use of molluscicide flies in Nour County in Mazandaran Province was studied from April to August 2015 and a total of 1269 mature samples were obtained from the following five stations using sweeping nets: Izad Shahr paddy field, Tirakdeh village paddy field, Chamestan, Sabezeh Rud (Royan), and Nour. The samples were transferred to the University’s systematic animal studies laboratory following stabilization. Finally, after investigations and identity examinations it was found that the samples of the subfamily Phaeomyiinae had the one genus and one species. It was found that the subfamily Sciomyzinae consists of the following two tribe: Sciomyzini and Tetanocerini. The tribe (Sciomyzini) consists of three genera and five species whereas the latter one (Tetanocerini) consists of two genera and two species. Therefore, both of the subfamily have a total of six genera and eight species that the most abundant species are Pelidnoptera leptiformis and the least abundant species are belonging to Colobaea punctata ; and from the point of location , the most abundancy had been occurred in Sabze-rud royan and the least abundancy had been occurred in Tirakde village.

Ticks are very important to transmit some major diseases. The ticks are blood-sucking ectoparasites and feed on wild and domestic animals. This research was carried out to study hard ticks which infected long-eared hedgehogs. A total of 29 hedgehogs were collected from seven stations in country of Mashhad during spring and summer of 2009- 2014 when they are so active. Then, 25 infected hedgehogs were found. Totally, 68 ticks were collected from 25 hedgehogs including 46 adult ticks (25 males and 21 females). The ticks are belonging to Hyalomma anatolicum, H. excavatum, H. marginatumandRhipicephalus turanicus. This survey is the first description of R. turanicus on long-eared hedgehogs in Iran. Since hedgehogs are freely coming to gardens, stables and human habitation, it is necessary to pay attention of their infection. In order to get more information about hedgehog infections and their transferable diseases in our country, more investigations and researches on infections of hedgehog are required.

Considering the variability of shell color among Nerita spp. (Gastropoda: Neritidae), their apparent identification base on shell color is difficult. This study has attempted to reexamine the identification of the Nerita spp. of the Bandar-Lengeh intertidal zone, by using morphological characters in reliable identification keys. Sampling was carried out from rocky-rubble and sandy-rubble substrates shores in maximum low tide hours of winter 2014. Samples were collected and fixed in formalin, the morphology and biometric measurements were taken in laboratory and five characteristics were measured. Results revealed the presence of five species including: N. adenensis, N.albicilla, N. longii, N. polita and N. textilis in the area which N. adenensis and N. albicilla showed highest and lowest relative frequency with 28.1% and 7.4% respectively. Also high variation in shell color appeared in N. adenensis which indicating non suitability of this characteristic in genus Nerita Taxonomic studies. The results of this study increase our knowledge about gastropods in this part of the Persian Gulf, which could be useful to improve their conservation and management strategies.

Replacement of animal proteins of fish diet with herbal proteins is one of the main method for decreasing the food cost. 70% of phosphorus in plants is in the form of phytate which is unavailable for fish because of lack of phytase enzymes. The aim of this study was evaluation of probiotic potential of phytase-producing bacteria from different sources. In this study, five bacterial species with the highest ability of phytase production including Raoultella terrigena, Klebsiella oxytoca, Citrobacter farmeri,Klebsiella pneumoniae and Enterobacter cloacae were isolated from agriculture and aquaculture origins, were evaluated for possessing the probiotic characterization. Probiotical indices including: acid resistance, bile salt resistance, bacterial antagonistic effects, hydrophobicity and lack of pathogenicity in fish, were evaluated in all isolates. Lactobacillus casei (confirmed fish probiotic) were chosen as positive control. Hydrophobicity and Antibiogram). All 5 isolates were more resistance against acid situation than L.casei, whereas the highest resistance in Fish 12 and Phas 32. All 5 phytase producer bacterias were resistance to 0.5 and 3 percent of bile salts concentrations (P> 0.05). All isolates have not antagonistic activity against Yersinia ruckeri and Aeromonas hydrophila but, Lactobacillus casei showed mild antagonistic activity. Resistance to different antibiotics was not significantly different (p> 0.05). But Fish11 showed the greatest resistance to the antibiotics. The hydrophobicity percentages were higher in all tested bacterias compare to the positive control. In this study all phytase producer bacterias had almost similar potential probiotic indices which were comparable to confirmed probiotic bacteria, L.casei. Then for choosing the best isolate possessing phytase producing ability and probiotic potential, more in vitro investigations as well as in-vivo study should be designed.

The composition of fatty acids of the muscles, liver and carcass of wild and cultured Mesopotamichthys sharpeyi were determined by gas-liquid chromatography. In all the samples studied, the principle saturated fatty acids (SFA) and Monounsaturated fatty acids (MUFA) were palmitic (C16:0) and oleic (C18:1n-9) acids respectively. The results showed that cultured fish muscle and liver contained a higher level of polyunsaturated fatty acids (PUFA), particularly docosahexaenoic acids (DHA), eicosapentaenoic acids (EPA) and arachidonic acid (ARA) (p<0.05), whereas wild fish muscles contained a higher level of SFA. The results indicate that the fatty acids composition of Benni tissues were different by environment types and feeding qualities. Finally, the cultured Mesopotamichthys sharpeyi can be a healthy component in the human diet according to dietary fatty acids profiles requirement.

Anzali wetland has ecological importance since it hosts migratory birds and fishes in southwest Caspian Sea. Based on researches performed, Trace elements such as Lithium (Li), Barium (Ba), Strontium (Sr), Arsenic (As), cadmium (Cd), Cobalt (Co), Chromium (Cr), copper (Cu),Molybdenum (Mo), Nickel (Ni), lead (Pb), and Sulfur (S) in addition to petroleum compounds such as Polycyclic Aromatic Hydrocarbons (PAHs) are considered as the ubiquitous pollutants in Anzali wetland which their concentration is increasing there and can be a great hazard for wetland inhabitants. Our study assessed the effects of these pollutants on one of the most significant fish species living through the wetland, Rutilus kutum. In order to perform the study, ninety fries were exposed to polluted water from Abkenar area and Siahkishim part of the Anzali lagoon (in the form of 3 treatments and 3 replications). After first day of exposure no obvious effect on epithelial cells of gill lamellas were detected,but in liver cells some cases of cytoplasm and nucleous degeneration were detedted, while after 4 days anomalies such as disorganization in primary and secondary lamella; lamellar fusion and club shaped lamellas in gill samples and bile stagnation in liver cells were detected(P>0.05). Then 8 days of exposure resulted severe signs of alteration like lumen expansion and blood congestion in primary lamella in gill tissues and focal necrosis in liver tissues (P<0.05). Resulted alterations based on our observations were attributed to water pollution in Anzali wetland.

In this study health status of Shahroud River located in Qazvin Province was examined. Macroinvertebrate samples were collected by Surber sampler (area of 0.16 m2 with 100 micron mesh size) in 95 km river length at 9 sampling stations with 3 replicates in each station. Samples were taken in 45 day intervals from 11th Nov. 2011 to 9th Sept. 2012. The collected samples were preserved in 4% formalin solution and transported to the laboratory for identification and further analyses. Total abundance, EPT diversity, percentage EPT and EPT to CHIR ratio were calculated. Species diversity, richness and evenness were determined according to Shannon- Weiner, Margalev and Pielou indexes. Minimum abundance of macroinvertebrates were observed in summer and maximum in spring. The lowest and highest Shannon– Weiner values were 0.93 and 2.24, Margalev index 0.33 and 1.64 were observed in summer and spring at station 1 (upstream) and stations 8 and 9 (downstream) respectivelyThe lowest and highest Hilsenhoff Biotic index (HFBI) values were 3.29 and 6.37, were observed in winter and summer at station 1 (upstream) and stations 9 (downstream) respectively. The study showed that biotic and population indexes are capable of providing useful assessment of health quality in running water ecosystems.

Heavy metals pollutants are not biodegradable and they can bioaccumulated by marine organisms. Heavy metals are persistant pollutants which the persistance of high concentrations of them in ecosystems can be harmful to organism. In this study concentration of total Ni, Cd, Zn and Pb in muscle and hepatopancreas tissues of Metapenaeus affinis shrimp was estimated. For shrimp samples using trawl bottom during autumn (2013). Shrimps were collected from Mahshahr creek and Bahrekan Bay. For determination heavy metals (Ni, Cd, Pb and Zn), samples after preparation and drying were digested, then concentration of heavy metals in tissues of shrimp measured by Atomic absorption. In this study, the concentration of heavy metals (Ni, Cd, Pb and Zn) in shrimps in Mahshahr creek were higher than Bahrakan bay (P<0.05), probably because it was nearby Bandar Imam Petrochemical Company and a high amount of wastewaters are dumped at this part. Hepatopancreas tissue was contained the maximum concentration of heavy metals (hepatopancreas>muscle). The arrangement concentrations of heavy metals are Zn>Pb>Ni>Cd, in both stations. The mean heavy metals concentration in hepatopancreas and muscle showed significant difference (P<0.05). In this study, concentration of heavy metals (Ni, Cd, Pb and Zn) in muscle tissue of Metapenaus affinis was compared with WHO, FDA, Sciortino and Ravikumar and MAFF standards and it was found that the concentrations are lower than standard level and therefore they can be used for human consumption.

The present study investigated morphological difference populations of Capoetacapoeta in the upstream and downstream of Zarinerood River in Urmia Lake Basin. In addition, the role of important condition factors influencing morphological features was studied. In this study, a total of 85 sample of Siah Maahi (C. capoeta) were caught from the upstream (40 pieces) and downstream (45 pieces) Zarinerood River using Electrofishing. Samples anaesthetized using clove powder, fixed in 10% formalin and transferred to the laboratory. 21 morphometric and 7 meristic characteristics were studied. Standardized data to determine the differences between the populations and also to separate the populations in each of the traits analyzed using principal component analysis (PCA) and detection function analysis (DFA). The study showed that Siah Mahi populations in the upstream and downstream of Zarinerood River had not significant differences in meristic traits (p>0.05). Siah Mahi populations had significant differences in morphometric traits, but these differences will not separate populations. Differences in ecological conditions such as flow rate, temperature, oxygen, vegetation and nutritional status were diagnosed as important factors in morphometric differences between populations-studied.

Determine and examine the distribution of the macrobenthos were studied in Nur Rud River monthly within one year (Jul. 2011 to Jun. 2012) from 7 sites in three replicates using Surber sampler with the cross-section 35×35 cm. Environmental indexes (debit, temperature and pH) were recorded in each site. In total, 7881 macrobenthos belonging to 7 orders of 21 families were detected. The most prevalent orders were Ephemeroptera (family Baetidea). Based on the results, water’s debit and temperature were significantly effective in density and diversity; and pH only affected the diversity of macrobenthos significantly, as the maximum and minimum densities were observed respectively in Feb.-Mar. and May-Jun. The maximum frequency of the macrobenthos pertained to site 1, the headstream of Nur Rud, and minimum frequency of the macrobenthos pertained to site 7, the place where the sewage of the sand mine enters the river. On average, maximum and minimum of Shannon-Wiener index were observed in Jun.-Jul. and Dec.-Jan.; Simpson index were observed in Feb.-Mar. and Jun.-Jul.; and Margalef index were observed in Oct.-Nov. and Jan.-Feb, respectively. Over one year, mean Shannon-Wiener index for species diversity, mean Simpson index for species dominance, and mean Margalef index for species richness were obtained as 1.35, 0.31, and 2.40, respectively. The quality of water in site 1 and site 4 was respectively high and moderate.

Investigation of habitat use characteristics play an important role in their management and decision about appropriate management is feasible only with understanding of their habitat requirements. This study was conducted to provide distribution data of Barbus lacerta and determination of its habitat use characteristics in order to its better management and protection. In the present study for investigation of the habitat use characteristics of Kura barbel in Taleghan River, environmental variables, including depth, river width, current velocity, temperature, elevation and diameter of substrate stones in 33 stations from upstream to downstream were measured. Then this data were analyzed using Habsel software. The range of used and selected habitat were obtained with regard to the availability of the habitat variables for specimens larger and smaller than 90 mm. The results showed that both studied groups select similar ranges, including river width of 2.5-7.5 me, elevation of 1400-1600 m asl, temperature of 16-15°C and substrate with stone diameter of 24-30 cm i.e. The younger Kura barbel selects lower depth area with lower river width and current velocity that have substrate with large stones, whereas adults selects same area with deeper water (48-54 cm) and larger bed stones. Since there is little study regarding habitat suitability of riverine fishes, the findings of this study can be used in long-term protection program and management of this species. In addition, the results can provide prediction of its distribution based on the environmental variable of river.

The study aims to evaluate the reproductive factors as well as fecundity of two broodstock groups (Iranian and French generation) at the research center of genetic and breeding of cold-water fishes, Yasouj, Iran. Number of 10 broods from French generation and 15 broods from Iranian one were randomly selected, tagged and stripped to evaluate fecundity and future parameters. Total egg weight and egg diameter were computed using a digital balance and a caliper. After fertilization, the percentage of fertilized, eyed, hatched eggs and larval survival were assessed . Average fecundity and egg diameter in the French generation were 4080±306.47 and 4.93±0.089 respectively. Mentioned parameter in the Iranian were submitted to be 4247±276 and 5.17±0.1. Moreover, percentage of fertilized egg (98.8, 88.33), percentage of eyed eggs (94.5,71) and hatching rate (82.5,70) were submitted in the Ferench and Iranian groups respectively. A possitive relationship was observed between fecundity and fish weight in French (r= 0.36) and Iranian ( r= 0.52) groups. A linear relationship between fecundity and length fish was observed in rainbow trout French (r = 0.30) and Iranian (r = 0.36). In conclusion, it seems that fish fecundity is more affected by fish weight, not fish length.

The aim of this study is to evaluate the toxicity of tobacco extract on rainbow trout. According to studies, has been investigated more on harmful effects of tobacco and their compounds on human and less attention has been paid to beneficial use in industries. This study can be considered as a first step in the identification and development of tobacco beneficial use in other industries. Acute toxicity test was carried out in static condition according to the O.E.C.D standard method for 4 days and physicochemical parameters of water were controlled including pH, dissolved oxygen and temperature. Thirty trout with an average weight of 5 ± 0.02 g were stocked in each treatment. After obtaining a lethal concentration range, the final treatments was carried out with five treatments to determine the lethal concentration (LC50 96 h). Quantitative results were analyzed by SPSS software version 16 and Probit statistical method with a confidence level of 95%. The lethal concentration of (LC50 96 h) tobacco extract for rainbow trout was 3.55 mg per liter and the no observed effect concentration (NOEC) be the equivalent of 0.35 mg per liter. Concentration of 0.01 LC50 96h recommended as safe level for aquaculture. While in the current study, concentration of 0.03 mg per liter is recommended for the rearing of rainbow trout larvae. It is recommended to use an aqueous extract of tobacco in low concentrations in trout farms, and according to the findings, also suggest non-toxic, effective and maximum allowable concentration of 0.03 mg per liter for safe use on farms.

In this present study, 240 three-spot gourami (Trichogaster trichopterus) fallowing was exposed to 17-β estradiol at stage of development including prior to maturity (larvae) average (1.26±0.12 g). The 20 species per aquarium under the four treatments (0, 10, 25 and 50 mg per kg of food) in three replicates were performed in a period of 90 days. Hormone was added to fish food. Results showed that treatments had no significant difference in fish growth, which correlated with increased amounts of 17- β estradiol (P<0.05), but the most growth was observed in treatment 3 (25 mg/kg of 17-β estradiol per fish). Also had no significant difference in number of white blood cells and hematocrit percentage between treatments (P<0.05). Although sex reversal was not significantly different from other treatments, it had increasing effect with increasing 17-β estradiol rate.

An experiment was designed to determine the optimum dietary protein level of a fresh water ornamental fish, Oscar (Astronotus ocellatus). Fish were fed with four isocaloric dietaries and 40%, 45%, 50% and 55% protein levels for 8 weeks. The highest and lowest weight gain were observed in fish fed with 40% and 50% dietary protein, respectively. Only, the significant difference of weight gain was observed between 40% dietary protein than other dietaries protein (P<0.05). The lowest and highest protein efficiency ratio were obtained in 55% and 50% dietary protein, respectively. But, there was not any significant difference of protein efficiency ratio between various dietaries protein (P>0.05). The lowest and highest specific growth rate were observed in 40% and 50% of dietary protein, respectively. The best feed conversation rate was obtained in fish that fed with 45% dietary protein. Results obtained from the feed conversation rate parameter of Oscar fish showed that with increasing the dietary protein from 40% to 45%, better feed conversation rate can be seen in fish, but, with further increase of dietary protein to the 50% and 55%, feed conversation rate parameter will increase.

Hezar Jarib Hunting Prohibited Area with 49000 hectares surface is located in east-southern parts of Behshahr and south of Galoogah County in Mazandaran Province and has a rich flora and fauna. The purpose of this study was to identification of snakes' fauna of Hezar Jarib Hunting Prohibited Area through the analysis of morphological characteristics and the use of valid identification keys. Specimens were collected from different parts of area and were transferred to the Zoological Laboratory of Islamic Azad University, Damghan Branch. Results show that all of the specimens belong to the order Anura and from three families: Hylidae, Bufonidae and Ranidae. Totally four species were identified: Hyla orientalis (6%), Pseudepidalea variabilis (33%), Rana pseudodalmatina (12%) and Pelophylax ridibundus (49%). Significantly, Pelophylax ridibundus and Hyla orientalis had the maximum and minimum abundance in the area, respectively. Snakes belong to three families: Colubridae Typhlopidae and Viperidae. Totally, eleven snake species were identified: Dolichophis jugolaris (2%), Hemmorohis ravergieri (4%), Telescopus fallax (4%), Platyceps najadum (5%), Dolichophis Schmidti (9%), Zamenis persicus (11%), Elaphe dione (15%), Notrix notrix (15%), Notrix tessellata (24%), Typhlops vermicularis (4%) and Gloydius halys caucasicus (2%). Significantly, Natrix tessellata has the highest frequency and Dolichophis jugularis has the lowest frequency in this area.

In the present study, LC50 value of Malathion, an organophosphate insecticide, was determined in Caspian Roach (Rutilus rutilus caspicus). Also four groups of experimental fish (containing 30 fish in each group) were exposed to different concentrations of Malathion. 0, 0.01, 0.05 and 0/1 ppm respectively for 23 days and effects of Malathion on gill and liver tissues were examined. Each treatment has 3 replications. Tissue sampling to histological study was done in third, thirteenth, twenty-third days and also 30 days after recovery. Results showed that LC50 value of Malathion in Caspian Roach is 6.5 ppm. In addition tissues of control group (0ppm) were normal and there were no damages, yet there were hepatocytes degeneration, picnotic in nuclear, hepatocytes vacuolization, vascular congestion and sinusoid congestion in liver of other groups and lamella hyperemia, hyperplasia, lamella fusion, necrosis lamella, increasing in mucosal cells, clubbing and telangioctasia in gills. There were more damages in longer times and in higher concentrations.
