Markazi province with high elevation mountains consist suitable habitats for wild goat as a representative of biodiversity in Markazi province. Wild goat habitats in this province is fragmented and degraded due to intensive industrial, agricultural and mining activities. Ecological niche factor analysis and landscape characteristics including patch shape, area and edge were studied to develop habitat suitability modeling and analyzing patch fragmentation. Results indicate that four ecological factors explain 93% of species habitat selection information. Marginality value of 1.603 and tolerance value of 0.299 indicate that wild goat preferred habitat with elevations and slopes higher than habitat's mean and had low tolerance to habitat variations. About 8% of southern parts of Markazi province encompass three suitable habitat patches for wild goat. Comparison of landscape characteristics of these three patches showed that HaftadGholleh- PalangDareh patch with an area of 63.25 %, edge density of 13.04 m and total perimeter of 761 kilometer is less disturbed by human made structures and more parts of it is under protection and therefore has more suitable condition than two other patches. In order to reduce the fragmentation of wild goat habitats in Markazi province, suitable patches should be developed and corridors should be designed.

This study was conducted to determine biological characteristics of threadfin bream (Nemipterus japonicus) in Persian Gulf (Bushehr Province), during November 2006 and October 2007. The minimum and maximum specimens were 75 - 273 mm FL. Based on the power relationship between fork length and weight, slope (b) for individuals was 2.987321. The emptiness value (V) was 45.6% and it shows that N. japonicus is a moderate feeder. The results of Fp indicates that crustacean with 78.2% are main foods, mollusca (27.7%), fishes (20.7%), polychaeta (19.2%) and Foraminifera (11.7%) were identified as minor foods and phytoplanktons (9.9%), nematode (8.0%), echinodermata (2.3%) and sea weeds (0.3%) were random foods. Ultimately, it was found that threadfin bream is a carnivorous species and from point of feeding intensity is a moderate feeder.The overall sex ratio was estimated as M: F =1.0: 2.6.The maximum GSR values were recorded in April and then in September for females and in September and then in April for males. The reproduction studies showed the spawning season extended within 2 peaks, from April- May and September and main spawning occurs in spring season.

Allium porrum L. (Leek) has been widely used in Persian foods as a flavor component and in Iranian folk medicine for treatment of gastrointestinal and infectious complaints. In the present study, effect of hydro-ethanol extract of the leaves was investigated for releasing insulin from the pancreatic beta cells in streptozotocin-induced diabetic rats. Rats were injected (i.p.) with streptozotocin 70 mg/kg. The hydroethanolic extract was administered at doses 50, 100, 150 and 200 mg/kg for 16 days, intraperitoneally. After administration period, the animals were anaesthetized by diethyl ether. Blood samples were drawn from the heart. Serum glucose levels were determined by the glucose oxidase method. To determine the insulin releasing activity, the pancreas was excised, fixed in 10 percent formaldehyde and embedded in paraffin for sectioning. Pancreatic sections of 5 micron were processed for examination of insulin-releasing activity using an immunocytochemistry kit. The results showed that administration of the hydroethanolic extract exhibited a significant reduction in serum glucose. Administration of streptozotocin decreased the number of active Langerhan’s islet in comparison with normal rats. Treatment with the Allium porrum leaves extract increased significantly the active Langerhan’s islet in comparison with the diabetic control rats. So, the plant has hypoglycaemic effect by increase insulin secretion.

Some supplements like kaolin accelerate growth and survival of animals; hence this additive was trialed on Rutililus frissi kutum. Six-hundred advanced fry fishes with average weight of (0.7 ± 0.062 g) were randomly distributed between 15 tanks of 500 L capacity. Five diets containing 0.5, 1, 1.5, 2 and 2.5 % kaolin with iso-nitrogenous (35%) in triplicate group were considered. With increasing kaolin to 2%, growth and food efficiency were improved and was significant with other treatments (P< 0.05).Treatments 1 and 5 (0.5 and 2.5 percent) with minimum and maximum levels of kaolin were shown unimprovement in growth performances (P<0.05). Carcass chemical compositions of kaolin in different levels were not shown any significant different among treatments; however with increasing kaolin to 2 and 2.5%, total ash contents were increased (P< 0.05).

The aim of present research is morphological study of versicolored wood snake, Hemorrhois ravergieri (Reptilia: Colubridae) in most provinces of Iran. It is non-venomous snakes that can be seen in the mountains and slopes, plains and semi-desert regions. We studied 34 snakes from different provinces of Iran. Sexes of specimens were identified with observation of hemipenis in live male snakes and dissection of fixed materials and study of testes and ovaries. Meristic characters were counted in scales under a stereomicroscope and metric characters were measured with caliper and ruler. In the results of this study, the average length and width of head and snout-vent in male snakes was more than females (P≤0.05). Also the number of ventral scales was 184-223 in all of specimens. The average number of ventral scales of adult specimens was 200.18 that counted 205.1 in the adult females and 196.08 in male specimens (P≤0.05). The number of dorsal scales of midbody was 21and anal divided in the all of specimens. There is no difference in the number of postoculars, preoculars, postnasal, prenasal and loreal scales between specimens.

In order to isolate and to identify naphthalene degrading bacteria from Nayband Bay sediments and to optimize biodegradation efficiency using the most effective isolated strain, surface sediment samples were collected from Nayband Bay mangrove forests. Obtained samples were then cultured on mineral salts medium (MSM) containing naphthalene as a sole carbon source. At the end of the enrichment, three bacterial strains in the consortium were isolated by spreading the 10-fold serially diluted consortium on nutrient agar plates. Naphthalene biodegradating efficiency of the isolated strains was monitored in two culture media: 1-MSM + naphthalene, 2-MSM + naphthalene + Tween-80. The ability of bacterial isolates to degrade naphthalene was studied by using gas chromatography. Among the isolated strains, SBU3 was found to be more efficient, degrading naphthalene in presence and absence of Tween-80, 60.45% and 39.30% respectively. This strain was identified by 16s rDNA gene sequence and results showed that it has 99% similarity to Marinobacter aquaeolei. The Optimum pH and C/N molar ratio for the biodegradation of naphthalene were studied in presence of 1% tween-80, results show that the pH 7.5 and C/N ratio of 100:10 were the optimum conditions and more than 85% of naphthalene removed within 7 days. Furthermore, the biodegradation kinetics of naphthalene corresponded with the first-order rate model.

Copper is one of trace elements which is essential for enzymatic reactions and is toxic to fish. But its compounds use for algae control and for prevention and treatment of fish disease. In this study, the effects of copper toxicity (copper sulfate) on gill and liver tissues of Oncorhynchus mykiss, were evaluated. 4 aquariums containing ten fish were used. One aquarium as control group and 3 others exposed to 0.2, 0.4 and 0.8 mg/l copper sulfate. Tissue samples were obtained 24, 48, 72, 96 hours after copper sulfate exposure and processed by Hematoxyline- Eosin staining method. The main histopathological changes observed were lamellar aneurisms in gill tissue and bleeding in central vein of liver tissue. These results suggest that exposure to copper as a heavy metal, has toxic effect on vital organs of fish. These toxic effects are various in different species.

We studied some aspects of the population dynamics of the ark clam Barbatia decussata in Bostaneh, Lengeh port, Hosseinabbad and Koohen rocky coasts of the Persian Gulf. Samples were collected monthly from August 2011 to September 2012 through quadrate sampling method (area 0/25m2). Shell length of 7064 individuals as well as total live weight and wet weight of 2065 individuals were measured in this study. By length–frequency distribution data, a von Bertalanffy growth function was established with an asymptotic length of 57.75mm, growth constant of 0.47year-1 and t0 (age at zero length) of -0.29 year. Asymptotic weight, natural mortality and longevity were 40.38g, 0.92 year−1 and 6.29 years respectively. We calculated two equations for the shell length with total live weight (TLW= 0.0001SL3.181) and shell length with wet weight (WW=0.000015L3.347) relationships that could be applied in future studies to estimate weight of B. decussata based on shell length. In this study shell length- age also total weight - age relationships were Lt= 57.75 [- e-0.47 (t + 0.29)] and Wt= 40.38[1-e-0.47 (t+0.29)]3 respectively. The growth performance index was 3.2 and the “b” value of the shell length– total weight relationship was 3.181 during the study period. Sex ratios did not significantly deviate from the proportion of 1:1 and the recruitment pattern was continuous with 2 major peaks.

This investigation aims to evaluate the role of dietary tryptophan on the growth performance carcass synthesis of fingerlings of Caspian Roach (Rutilus rutilus caspicus). Fingerlings (mean weight: 1.91 ±0.01 g and total length of 6.21±0.07 after adaptation were divided to 3 groups (0.25, 0.5 % of diet and one control (0%)). Mean weight and total length difference of treatments were not significant. Carcass synthesis (without head and skin) and body composition showed significant difference between treatments (p<0.05). Lipid content of body decreased significantly as tryptophan increased (p<0.05). Effect on food intake in higher vertebrata and fish is a result of tryptophan which increases serotonin levels of brain and can effect on weight gain and also can increase protein content of carcass and decrease lipid content in Roach.
