Nitrification rate of biofilters is influenced by ammonia concentration and levels of ammonia vary in response to feeding time. On the other hand, existence and activity of different groups of bacteria can be expected in the biofilters. Hence in this research, nitrification dynamic of biofilters during day hours and also rules of different biofilteration process (nitrification, denitrification and anamox) in aerobic biofilters of Common carp recirculating aquaculture system were surveyed. To conduct of this research 12 pilot recirculating aquaculture systems with barley straw, wood chip, sponge and PVC pure pipe based biofilters were designed. After activation of biofilters, nitrification rates measured at day 46 and 61 in 4 hour interval and via sampling of granules from biofilters at day 62, nitrification, denitrification and anamox process were surveyed. Results indicated that nitrification rates were different during day hours, as so peak rates observed in related to feeding time. Nitrification rates in batch culture of granules were greater than maximum rates obtained for biofilters established in recirculating aquaculture systems and these granules showed not only nitrification but also denitrification and relatively anamox activities. In conclude by modifying the management of biobilters all biofilteration process of inorganic nitrogen wastes can be useful.

Abstract This study was conducted with the aim to evaluate efficacy of applying 4 different formulations of Beauveria Bassiana (BB) fungus spore to combat Hyalomma ticks. Formulations used included: 1) Distilled water with 2% Tween and BB; 2) Distilled water with 10% cottonseed oil, 0.01% sucrose, 0.2% tween and BB; 3) Distilled water with 10% liquid paraffin, 0.01% sucrose, 0.2% tween and BB, anddistilled water as the control group. Concentration of 1.76×108 was used in preparing formulations. The four prepared formulations were equally sprayed on 128 engorged mature ticks, in 4 groups. Number of dead tick due to spray of formulations were counted in the following days. Treatment effect on mortality of ticks, was assessed using time-survival analysis. 9 days after spraying different formulations, it was found that formulation containing BB fungus had eliminated 50 to 55% of the ticks. Due to the fatality of 55 percent Hyalomma ticks in this research, it can be hoped that in the future with further research, oil suspension containing BB fungus can be used to combat Hyalomma ticks.

In order to study and identify macrobenthic invertebrates’ fauna of Dadin Spring in Kezerun, Fars south-west, Iran was conducted from April, 2014 to March, 2015. Benthic samples were collected from five different stations of spring including: center, north, south, west and east. Sediment was performed by using Van Veen Grab. After washing the sediment to avoid spoilage, organisms were fixed with 1% formalin and then macrobenthic invertebrates were identified based on key identification. The results showed that three phyla of macrobenthic invertebrates were diagnosed in the Dadin spring which these three phyla including Arthropoda, represented by seven genera: Epitheca sp., Argia sp., Chironomus sp., Chysops sp., Hydropsyche sp., Potamon sp., Caridina sp.. Annelida represented by two genera, Uncinais sp. and Lumbriculus sp. and Mollusca represented by four genera of gastropods including Theodoxus sp., Monacha sp., Melanopsis sp. and Melanoides sp.. Mollusca dominated the macrobenthic invertebrates with a total abundance of 48% and Annelida were the least abundant, 15.5% by number. Although the abundant of Arthropoda was less than Mollusca (36.75%),but the diversity of Arthropoda was more than others. One-way Aonwa showed that there was significant relationship between collected samples and season (P≤0.05) while this relationship was not seen between collected samples and sampling station(P>0.05).

Abstract Captive breeding program is one of the ways which lead to species conservation and hence, introducing them to the native distributional range. Dashte-Naz protected area with an area of 55 hectares in the north of Iran is one of the important place forcaptive breeding of Persian fallow deer. Despite of the widespread use of this approach in the world, there are some problems such as genetic issues and lack of suitable place for captive breeding. In this study SWOT analysis applied to identify of strengthens, weakness, opportunities and threats in captivate breeding plan for Iranian fallow deer, sustainable management strategies of species, improvement of reproducibility performance and reducing its negative effects. Quantitative strategic planning matrix was determined as the best strategies. Among different strategies, movement of individuals between different habitats to reduce genetic vulnerability, search for new places to introduction, analysis of populations survive, use of descendants tree in populations pedigree, design mating table and registration information of individuals were identified as the most important strategies.

This study carried out on 194 fish (Garra rufa) during the months of January to March at eight stations in Dinvar River located at Kermanshah province. During this study, 34 attributes and 11 traits count was measured geometric parameters and natural mortality and total amount 0.346, infinite length L∞=124.57 mm, growth factor K=0.29 and the length and weight of the exponential function of growth were calculated. The length-weight relationship was calculated for each season separately, which indicates isometric growth during summer and autumn and allometric growth during the winter and spring seasons. The length-weight relationship for the whole year was calculated aqual to W= 1/000095L2/97. Male to female sex ratio of 1: 1.44 were calculated for faster growth in males and natural selection is directed towards the elimination of larger samples. Results indicate that the Dinvar river is a good place for spawning and nursery to Brood fish. The data were confirmed by isolation of populations between the stations and it seems that fish populations of stations are panmictic. However, further studies confirm that these results depends on genetic traits, physiological and Osteology Lange populations.

Abstract Cotton aphid, Aphis gossypii Glover (Homoptera: Aphididae), is one of the polyphagous and highly damaging species in fields and greenhouses. Now, aphids control is dependent on using chemical insecticides. Because of continuous use of pesticides, many species of aphids have become resistant to many chemical compounds. Then, surveying the alternative approach needed for effectively managing of aphids in integrated pest management (IPM). In this study, the qualitative phytochemical of ethanolic extract of Salsola imbricata and its insecticidal effect on A. gossypii investigated in a completely randomized design under laboratory conditions. The results showed, the mortality rate of one-day adult aphids treated with ethanolic extract of S. imbricate at concentrations between 33.63 to 2016.99 µg/cm2 was 20 to 73 %. The LC50 value after 24 hours was 340.06µg/cm2. Preliminary phytochemical study of extract showing the presence of various bioactive and insecticidal compounds in ethanolic extract of S. imbricata, like glycosides (anthraquinones), flavonoids, steroids, tannins and tri terpenoids compounds.

Abstract The change of land use can change the components of the habitat quality and population structure of aquatic organisms. The purpose of this study is to use a combination of macroinvertebrate to assess the effects human activities such as agriculture, rural, fish form, and forest and reference site (upstream) along the Zarin-Gol River, Golestan province. Sampling of macroinvertebrate was performed monthly in two season (winter and spring) 2015-16 and nine stations (in different land use along stream) with Surber sampler (0.09 square meter) in three replications. A total of 1929 samples were collected from macroinvertebrate belong to 30 families and 9 orders. The highest abundance of Ephemeroptera and Trichoptera was observed in spring and in the stations 6, 7, 8 and 9 and Diptera was the rest. The maximum value of Shannon diversity index and Margalef richness was obtained in the stations 6, 7, 8 and 9. The cluster analysis of different stations and season showed three distinct groups. The results showed that the land use fluctuations based on human activities caused a decrease in abundance and diversity of macroinvertebrate (reduction of sensitive organisms and increase of resistant organisms).

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.

Macrobenthos communities are used as the second and third levels of food chain, and can be considered as an index of total production and water quality. This study aimed to investigate the density and abundance of macrobenthos in the Zayandeh-rood River in 2017 and use them to determine the river water quality. For this purpose, 6 sampling stations were selected completely randomly and sediment samples was collected at each station with three replications in 4 seasons. Benthos identification was performed using binocular stereomicroscope and Benthos identifiers keys. Finally, 9 families and 7 order were identified, among which Monhysteridae, Oligochaeta and Hirudinea had the highest abundance. All seasons and stations are classified as serious organic pollutants based on the ASPT index. According to the EPT index, in spring, water quality was assessed as good. Summer and fall were in poor and winter in very poor quality class. Shannon Weiner index for all seasons is in the moderately pollution class. All of the seasons according to the BMWP index, were in moderately class. Based on BMWP index, stations 1 and 3, the water in poor quality and the other stations were in the moderately quality.

Abstract Variable toad (Bufotes variabilis) is a member of the Bufotes viridis complex in Bufonidae family. Although this species broadly spreads in the western part of Iran, few studies have been carried out on different populations of this species in Iran, especially in Khuzestan province. Totally 59 specimens were collected from Behbahan, Masjed Soleyman and Dehdez from June 2016 to September 2017. Analysis of variance (Anova) confirmed the separation of populations in 11 characters. The results of t-test showed no sexual dimorphism in the studied populations. The results of the discriminant analysis showed that both functions are significant. Scatter plot of canonical functions shows that according to the first function, the specimens of Behbahan are partially separated from specimens of two other regions and according to the second function, specimens of the Masjed Soleyman are clearly separated from specimens of two other regions. Overall, 89.8% of the toads were placed in their expected groups. Karyological studies demonstrate that all samples are diploid and have 2n=22. These chromosomes are classified into two groups. The first group consists of 6 pairs of large chromosomes and the second group contains 5 pairs of small chromosomes. In all samples of the three mentioned areas, 8 pairs of chromosomes are metacentric and 3 pairs of chromosomes are sub metacentric. Such karyotype pattern has been reported in many species of the genus Bufotes.

Recent reports have shown that some Plant Isoflavones have beneficial effects on diabetes and liver health in human and laboratory animals. The aim of this study was to administrate of hydroalcoholic extract of Trifolium pretense (red clover) as a plant rich in Isoflavones compounds and its effects on serum levels of glucose and liver enzymes (AST, ALT and ALP) in mice. In this experimental study, 42 male mice were divided into 6 groups of 7, including healthy control, diabetic without treatment (positive control), diabetic treated with glibenclamide groups, and three diabetic groups treated respectively with 250, 500 and 750 mg/kg of hydroalcoholic extract of red clover by gavage for 15 days. Diabetes was induced by intraperitoneal injection of streptozotocin, 60 mg/kg. On the last day, serum glucose and Liver Enzymes (ALT, ALP and AST) levels were measured. The data were analyzed by SPSS statistical software and OneWay ANOVA test. The significant was shown with (P<0.05).Doses of 500 mg/kg and 750 mg/kg of extract were significantly (P<0.001) decreased serum glucose compared with positive control group. Assessment of liver enzymes shown that AST level in 750mg/kg group (P<0.001), ALT level in 500 mg/kg (P<0.01) and 750 mg/kg (P<0.001) groups, and ALP level in 250 mg/kg (P<0.05), 500 mg/kg (P<0.001) and 750 mg/kg (P<0.001) groups significantly decreased compared with positive control group. It seems that the red clover has anti-diabetic and hepatoprotectiveeffects.

The aim of this study was to investigate the analgesic effect of Satureja bachtiarica Bunge essential oil by formalin test in mice model in this study, S. bachtiarica Bunge essential oil was prepared using clevenger apparatus by distilled water method. Mature male rats (25-35 gr) were selected. Acute and chronic pain induction was performed by injection of 20μl of 4% formalin solution to evaluate the analgesic effects of S. bachtiarica essential oil. The study groups consisted of the control group receiving normal saline, the groups receiving 25, 50 and 100 mg/ kg of S. bachtiarica essential oil, and the positive control group received morphine 10 mg/ kg. Single dose injections were performed 30 minutes before the start of the test. Acute pain (5 minutes after injection) and chronic pain (20 minutes after inoculation) were measured by stopwatch and the results were analyzed by SPSS16 software.S. bachtiarica Bunge essential oil at doses of 25, 50 and 100 mg/kg significantly moderated formalin-induced pain as it could reduce foot licking caused by formalin injection in both acute and chronic phases. The present data indicate that essential oil of S. bachtiarica Bunge has analgesic effect on mice, and this plant could be considered in future health care.

Abstract
The most common diseases are neonatal jaundice at birth which leads to a yellowish skin of the infants and the white eye due to an increase in the amount of bilirubin in the baby's blood. Naturally, bilirubin passes through the liver and is excreted as bile from the intestine. Neonatal jaundice occurs when bilirubin is produced earlier than the ability of the neonate liver to decompose and dispose of it. The aim of study was to determine the prevalence of neonatal jaundice and its risk factors.
In this descriptive study, 1000 neonates hospitalized to the Neonatal Department of Maryam Hospital of Karaj were examined by easy non-probability sampling. Total bilirubin, G6PD, hemoglobin, RH, blood group, as well as gender and delivery method. In this study, 36% of infants were affected by jaundice. The lack of G6PD activity in jaundice was 10.5%. The prevalence of preterm jaundice was ABO incompatibility, RH incompatibility and G6PD deficiency. The age and weight of the infant at the time of visit, the incidence of jaundice and the weight of the baby at 3 to 10 days in the groups were not significantly different. The mean of bilirubin in infants born with normal delivery was 3.8 and in cesarean section were 11.2. Amount of jaundice and its severity in neonates of cesarean section is higher. Total bilirubin in female neonates did not differ significantly with males. Part of the prevalence of jaundice was due to abnormality of ABO and RH and deficiency of the G6PD enzyme. The results show that other factors also affect jaundice. Approximately 80% of infants who lack the G6PD enzyme deficiency or incompatibility of the blood group showed that the level of bilirubin was much lower than that of normal infants.

Abstract Persian squirrel (Sciurus anomalus) is one of index mammals of the Zagros Oak Forests, as for is very poor of the natural forest cover in Markazi Province, therefore existence of trees dominant typeof species Quercus Brantii persica in the Forest Reserve Area of shazand is of great importance for the regeneration of this species.The study was using MaxEnt and statistic methods with Seven variables i.e. tree height, diameter at breast height(DBH), cover crown, distance from roads and agricultural land, distance from the nearest tree, the number of trees has holes, and Frying rate of oak trees, and 60 hypothetical of simulated points of squirrel. The results indicate that an area of 6.4 ha, equivalent to 39%, in the forest reserve area of shazand is habitat suitable for the Persian squirrel. The model validity is 0.845 revealing the excellent performance of MaxEnt method. According to, the habitat conditions of available does not exist of the possibility of regenerationof the Persian squirrel in the Forest Reserve Area of shazand now. The number of trees has holes, diameter at breast height, distance from the nearest tree, Frying rate of oak trees, cover crown and are respectively known as the variables with the greatest impact on habitat of Persian squirrel.

In this study, big-head carp flesh was processed and fish finger was produced by the formula of 1, 2 and 3 with 70, 80 and 93.5 percent of big head fish flesh respectively. Then sensory attributes, biochemical changes and nutritional value such as peroxide value (PV), thiobarbituric acid (TBA) and the total volatile nitrogen (TVB-N) changes and microbial load of all three formulas were compared with together. According to sensory data, the formula 1 was chosen as the selected product. Quality changes were studied for evaluators’ selected formula during storage at -18˚C on the days 0, 30, 60, and 90. The results showed that fish finger prepared with formula 1, had more acceptable scores than two other formulas. The results indicated that the minimum and maximum amounts of protein belonged to the formulas 1 and 2, respectively. The amount of protein, lipid, carbohydrate and calcium of the selected product decreased during the storage and the moisture had an increasing manner. The results of the study on the changes of PV, TBA and TVB-N showed that the minimum and maximum of PV belonged to formula 3 and formula 1, and the minimum and maximum of peroxide were observed on days 30 and 60 of storage, respectively. Microbial count showed that according to increasing storage time, total count was decreased. According to the results, maximum of shelf life for the samples stored at -18˚C was 90 days.

Abstract The ground beetles (Coleoptera: Carabidae) are powerful predators and have important role in biological control of agricultural pests. The fauna of these beneficial insects was studied in fruit orchards and rice fields of Mazandaran province during 2015-2016. In total, 22 species within 16 genera and 10 subfamilies were identified in different regions of Mazandaran. The samplings indicated that the highest species diversity was observed in Amol and Qaemshahr, and the lowest species diversity in Babolsar; also the highest population density was observed in Qaemshahr and Behshahr, and the lowest one in Babolsar and Noor regions. Among the studied species, Harpalus griseus (Panzer, 1797) had the highest distribution and Acinopus megacephalus (Rossi, 1794), Bembidion menetriesi Kolenati, 1845, Carabus roseni Reitter, 1897, Chlaenius steveni Quensel, 1806 and Calosoma maderae dsungaricum Gebler, 1833 the lowest one. Also, the highest population density was obtained for H. griseus and Harpalus fuscicornis Menetries, 1832 and the lowest one for A. megacephalus, B. menetriesi, C. steveni, Cicindela rhodoterena Tschitschherine, 1903, C. maderae dsungaricum and Zabrus spectabilis Hampe, 1852, respectively. The results indicate that Harpalus griseus and Harpalus fuscicornis are the dominant species in the most sampled regions of Mazandaran province.

Abstract The objective of this study was to determine the body shape variation among Kura barb species (Barbus spp.) in the Caspian Sea, Urmia and Tigris basins using landmark-based geometric morphometrics. For this purpose, a total of 128 specimens were sampled from the three basins using seine, gill and cast nets. The left side of each specimen was photographed using digital camera and 14 Landmark points were digitized on two-dimensional images using TpsDig2. Landmark data after a Generalized Procrustes were analyzed using Principal Component Analysis (PCA) and Canonical Variate Analysis (CVA) and the patterns of body shape differences among the studied population were illustrated in deformation grids in relation to consensus configuration of all specimens. The Principal Component Analysis could not differentiate the populations, but CVA displayed some differences among the populations. Habitat-associated morphological divergence, phenotypic plasticity and evolutionary process of body shape change among various populations and also, a relationship between the geographical distance and the degree of morphological divergence among populations in response to environmental factors in their habitat were observed. Thus, each population should be considered as separate genetic and morphological stocks.
