In recent years, many of Wheatears' hybrids have been recorded based on new work on old sub-species and geographical variation. One of the forms with little available data in Iran is vittata. For some time, the vittata phenotype of Wheatear has been considered as a subspecies of Pied Wheatear Oenanthe pleschanka (Lepechin, 1770). Systematic location of Oenanthe pleschanka vittata remains unclear for some reasons. Since spring of 2009, this rare phenotype has frequently recorded in eastern and north parts of Alborz Mountains, Quchan, Disful and Arsanjan between April and August. Also, the hypothesis that vittata could be an intermediatetaxa resulted from hybridization between O. pleschanka and O. hispanicahad investigated. But interesting enough the geographical distribution range of vittata did not occur even in the hybrid zone of this species pairs. Our data based on 37 morphometrical characters did not support the separation of vittata from pleshanka. Discriminant analysis and canonical discriminant functions of mentioned characters could not separate vittata and Pied Wheatear. Further studies using molecular data could possibly give more resolution on the systematic situation of this taxon. Additional data about the nesting, breeding, singing, and courtship behaviors are required.

This research was conducted in 2010 with purpose to evaluate the effect of monsoon phenomenon on variation of metals concentration including Cd, Cu, Ni, Pb and Zn in shell of oyster Saccostrea cucullata from intertidal zone of Chabahar coasts (along the Gwatr to Pozm). For this purpose, the Gwatr, Beris, Ramin, Chabahar, Tis and Pozm stations were selected. Samples of oysters were collected from the each station in the preemonsoon, monsoon and postmonsoon seasons (including May, August and November respectively) during low tide. After preparation of samples, heavy metal concentration was determined by using the atomic absorption spectrophotometer method. The average concentration of Cd in premonsoon, monsoon and post monsoon was determined 0.41, 1.36 and 1.90, Cu 1.56, 1.058 and 0.46, Ni 2.49, 11.55 and 10.48, Pb 0.47, 0.90 and 1.02 and Zn 7.65, 6.86 and 4.47 µg/g dw respectively. Increases of Cd concentration during preemonsoon and post Monsoon may probably be as a result of the upwelling currents and increase of phytoplankton productivities that can be content of Cd. Increase of Ni and Pb concentration from preemonsoon to post Monsoon seasons could be due to the monsoon activity and the change of these elements concentration in surrounding areas. Therefore, this project determined; Monsoon phenomenon can be an important factor to change or fluctuate heavy metals concentration in shell of oyster in selected area of the Oman Sea.

The keeled-rock gecko, Cyrtopodion scabrum, is widely distributed in the south west of Asia and northern Africa. In Iran, this species is often found in most parts of the country and commonly known as the house lizard. In order to determine whether or not there is genetic difference between various populations, 45 individuals of this lizard were collected from 5 regions. After extracting DNA, the mitochondrial cytochrome b gene was amplified by PCR and then sequenced. The sequences were then analyzed by Mega 5 and PAUP software. The findings of present study showed that different populations of this taxon display a homology in respect to mitochondrial cytochrome b gene, since the average variation among these specimens was negligible, ranged from 0 to 0.1%. These results indicate that this taxon has recently been introduced to Iran and a strong gene flow still present within its various populations.

Selenium is an essential micronutrient element due to the antioxidant and anti-cancer properties have attracted much attention. Organic form of this element has high bioavailability and toxicity is very low. The goal of this study was evaluate the effect of feeding by Selenium-enriched Saccharomyces cerevisiae as an organic form on the growth and resistant of rainbow trout. For this purpose, Six hundred rainbow trout with 29 ± 4 g mean weight were fed for a period of 60 days with a commercial pellet containing different concentration of Selenium Enriched yeast (106, 107 and 108 CFU/g of diet) and control diet (without complementation). Sampling was done for biometry at the day of 0 and 60 and at the end of trial the fish were challenged with thermal and hypoxia stresses, also an experimental challenge was scheduled with Yersinia ruckeri. Results showed that the addition of Selenium enriched yeast into the fish diet significantly (P<0.05) improved rainbow trout growth parameters in comparison the control. Also, the fish that received maximum level of Selenium enriched yeast (108 CFU/ml) had higher resistant against stresses and Yersinia ruckeri than the other groups. In conclusion, addition of selenium enriched Saccharomyces cerevisiae into diet could enhance the growth and resistant of rainbow trout against environment stresses and disease.

Urolithiasis is a worldwide problem, sparing no geographical, cultural, or racial groups. Kidney stones are composed of inorganic and organic crystals amalgamated with proteins. Crystallisation and subsequent lithogenesis can happen with many solutes in the urine. Calcareous stones are still by far the most common nephroliths accounting for more than 80% of stones. In Iranian folk medicine, many plants are used for the treatment of kidney stones. In the present study, effect of Equaisetum arvense L. aerial parts hydro-alcoholic extract on calcium oxalate crystallization was studied in male rats. At first, hydro-alcoholic extract of plant at doses of 25, 50 and 100 mg/kg were prepared. Crystallization of calcium oxalate was induced by adding ammonium chloride and ethylene glycol in drinking water for 3 and 38 days, respectively. Control group was treated by drinking water. Experimental groups were treated by plant extract at doses 25, 50 and 100 mg/kg for 41 days, interperitoneally. After 41 days, animals were anesthetized by ether and left kidneys removed and put them in buffered formaldehyde. Specimens were prepared for histological studies and stained by H&E staining method. Results showed that treatment of extract decreased the number of crystals in kidney sections of experimental animals in comparison with control group. Also, administration of plant extract decreased tubuleinterstitial damages in treated animals. So, the plant can prevent the formation of calcium oxalate crystals in kidney.

Otolith contour from two species of family Lutjanidae, Lutjanus malabaricus and Lutjanus johnii from Persian Gulf and Oman Sea were investigated for species separation. For that, 20 samples from each species in the first stage and 39 and 41 samples for L.malabaricus and L. johnii in the second stage were used, respectively. The image of extracted otoliths were taken, digitized and then analyzed using Shape Programm and Elliptic Fourier Analysis. For each sample, chain code, harmonic and elliptic Fourier coefficients were generated and medium otolith contour reconstructed by combination of these harmonics. The results showed that the number of samples is very important in species separation and with low number of otoliths it is not possible to separate species using this method. Therefore with choosing appropriate number of samples, it is possible to reconstruct the otolith contour for each species and detect the differences between two closely related species based on otolith morphology. This investigation is an effort to explain some benefits of elliptic Fourier harmonics in otolith morphology.

This study aimed to investigate the population of benthic communities in relation to heavy metal contents (Cu, Pb, Zn, Cr, Co) in sediments of Gorgan Bay. Thirteen sampling sites were selected and sampling was conducted using Van Veen sampler in summer of 1389. Regarding the obtained results, total organic compounds in the sediment ranged from %1.75 to %9 (averaged 4.45±1.72 (%)). The average amount of sand, silt and clay were 23.38±27.56 (%), 36.61±18.3 (%) and 39.76±14.40 (%), respectively. 5 classes, 8 families, and 8 species of macrobenthic communities were identified in Gorgan Bay. The population of macrobenthic communities ranged from 466.66 to 5100 (ind m-2) with the average amount of 2350.67±1450.78 (ind m-2). The indices of Eveeness, Shannon and Richness averaged 0.66±0.1, 0.78±0.45 and 0.69±0.35, respectively. Also, significant differences were observed amongst determined biological indices at various sampling sites (P<0.05). Concentrations of Cu, Pb, Zn, Cr, Co were 3.80-31.20, 4.10-18.30, 13-75, 3.50-20.80 and 13-52 mg kg-1, respectively. The average contents of heavy metal contents were (mg kg-1): Cu (17.86±9.19), Pb (11.33±5.16), Zn (42±23.23), Co (10.61±6.00), and Cr (31.69±15.71). Our results revealed that there was a negative correlation amongst all the determined biological indices and heavy metal contents in the sediment, demonstrating the negative impact of these metals on macrobenthic communities.

Mediterranean flour moth Anagasta kuehniella (Lep. Pyralidae) is a major pest of stored products which causes a lot of damage on stored products, especially flour and grains. Cereals which are rich in carbohydrates especially starch are the most important food source for flour moth. Thus the survival of the insect is dependent on alphaamylase enzyme activity that converts starch to simply-absorbed sugars. In this study alpha-amylase enzyme activity and pest fecundity were examined on ten wheat varieties. Fecundity rates were significant in different varieties. There was positive correlation between Fecundity rates and protein rates in different wheat varieties (r= 0.461). The activity of alpha-amylase enzyme in midgut of fifth instars larvae on different wheat varieties and inhibitory rate of different wheat extracts on the alpha-amylase enzyme activity in both sexes was significantly different. Most of wheat varieties had high inhibitory activity in both sexes. A negative correlation observed between alpha-amylase enzyme activity and Protein amount of different wheat varieties (r=-0.582 male, r=-0.453 female). The results showed that there was no correlation between inhibition of alpha-amylase activity and the fecundity average of females (r= 0.045) in different varieties of wheat.

The study was included seven treatments based six diets containing astaxanthine (A) and β-carotene (B) with three different levels of 50, 100, and 150 mg kg-1 of the diet, as well as a control diet which was devoid of any added carotenoid. The fish were fed using these diets for a period of 4 months. At the end of the experiment, the female fish were artificially bred with identical male fish (which were fed with the control diet). The various propagation indices in different treatments were compared. In the incubation phase, the fertilized eggs were incubated in batches containing 10000 eggs and 20000 eggs per liter. The result showed a significantly difference for egg fertilization rate betweendifferent treatments (P≤0.05). The egg survivability rate from fertilization up to the onset of gastrolasion stage turned out to be significantly different between treatments with normal density and treatment with double density (P≤0.05). In this stage, the egg survivability rate in the normal density treatment had higher than those treatments which had two times greater density than the normal one. In the egg development stage, and in the normal density treatments, the astaxanthine percentage out of the total carotenoid showed significant different rather than double density treatments. *

The pika, Ochotona rufescens, spends a considerable amount of time during spring and summer to caching vegetation. These caches (haypiles) have been as the main source of pika diet securance in winter, as a source of food for intermittent periods when the Pika is unable to forage elsewhere, or when food is scarce. In this study sixteen haypiles of pika was assessed to identify pika diet. As a result were identified 37 plant species of pika diet. Arrhenatherum kotschyi Boiss that was detected in 8 haypiles, Had the Highest frequency in plant species that was collected by pika.

Effects of Diazinon poisoning on some of hematological factors of white fish were studied in Sefid rood Fisheries research station in the summer of 1390. One hundred twenty fish were designed in 3 treatments and 4 replicates. Based on literature LC50 of the toxin, 25, 50 and 75 percent of the lethal concentration of Diazinon 60% were considered for this experiment. Blood factors such as hematocrit, hemoglobin, monocytes, and MCHC in fish exposed to the poison showed significant differences compared to controls (P<0.05). These changes could be indicating of spleen and liver malfunction that lead to anemia. The amount of neutrophil in experimental groups was higher than the control group (P <0.05). No significant difference in terms of MCV, MCH, lymphocytes, and eosinophils was observed (p>0.05).

Anesthetic effects of valerian (Valeriana officinalis) and Clove oil were examined on rainbow trout (Oncorhynchus mykiss) in two weight groups (mean weight 26.02± 6.3gr and 350.5± 5.09 gr) at 18oC and pH of 7.6. For this purpose concentrations of 5, 10, 15, 20, 25 and 30ml of valerian extract in 1 lit of pond water and 500 and 1000ppm of clove oil were prepared. In these experiments, immersion method was used for fish anesthesia. Four fish in each treatment with similar mean weight were exposed to aforementioned concentrations of anesthetic agents. The obtained results confirmed sedative and anesthetic effects of valerian extract on rainbow trout. Sedation and anesthesia were not observed in those fish exposed to clove oil within suitable time span (below 3 minutes) therefore clove oil treatment was discarded from the experiments. The most suitable concentration of valerian extract to induce sedation and anesthesia in smaller and larger weight groups were 15ml and 25 ml respectively and sedation, anesthesia and recovery were achieved in less than 3 minutes.
