Among the factors threatening biodiversity, habitat loss and habitat fragmentation are on top of major threats of habitat diversity that many protected areas has been unable to fulfill the functions defined. Therefore, analysis of the temporal changes of the protected areas and direction of composition and spatial distribution of the changes are requirements of the management of these areas The aim of this study was to investigate the temporal changes in habitat suitability as the basis of the protected areas and analyzing these changes by using landscape metrics for red deer (Cervus elaphus maral) in Hyrcanian forests of Lisar protected area in Gilan. Based on the results, besides the 35 percent decline in habitat suitability layer, we see an increase of 34 percent in the number of patches, 89 percent of edge density, 26 percent total of edge and reduction of 53% of the average size of patches. The results indicated a drop in the quantity and quality of habitat in the area investigated. This result confirms that increasing habitat destruction through the process of habitat loss and fragmentation has reduced the potential for the release and dispersal of the maral in habitat and gradually it provides the background of local extinction so reconstruction area is a key priority for management.No ecosystem is island and ecosystem sustainability depend on fitting the context of the ecosystem and the internal capabilities.

Iran, 4111Journal Article20151222Urial Wild Sheep (<em>Ovis orientalis arkali</em>) is the biggest wildsheep species of Iran which is distributed in east of country, as an indicator in hilly habitats. This species has been recognized as Vulnerable in Redlist threaten species, due to Habitat loss and fragmentation and poaching. As such, to improve management strategies, we should identify suitable habitats and diagnose influential factors for management and conservation. In this study we identified suitable habitats model of Urial according to the direct observation by means of Maximum Entropy (MaxEnt) software in Darmian Protected Area. We used 18 environmental parameters and the model could predict the high potency validity by AUC=0.92 in predicting habitat suitability. According to the results, the most suitable habitats for Urial are related to slope, elevation range of 2600 to 3000, annual mean temperature and maximum temperature in warmest month. The results showed that control of livestock grazing, habitat degradation due to agriculture and poaching are needed for effective Urial population management in Darmian PA.Urial Wild Sheep (<em>Ovis orientalis arkali</em>) is the biggest wildsheep species of Iran which is distributed in east of country, as an indicator in hilly habitats.

After DNA extraction, mitochondrial cyt-b gene was amplified by primers using polymerase chain reaction (PCR); then 1098 base pairs of this gene were edited for each sample after purification and sequencing processes. Then by analyzing of this partial sequence of the samples: polymorphism sites, nucleotide and haplotype diversity, the amount of genetic differentiation (using Fst index), Demographic history (using Harpending's raggedness index, Tajima and Fu Fs test) were calculated and phylogenetic tree and haplotype network were drawn by Baysian and Median joining logic in order. The results showed that there were 13 different haplotypes and 22 polymorphic sites between the samples and haplotype diversity was equal to 0.88. Fst (P<0.05) index was also equal to 0.6382 which due to this index and the results of the analysis of molecular variance (AMOVA), there is limited gene flow between populations and populations are distinct with each other to high extent.

According to the observations, the rate of mortality varied in different stages which could be due to the pressure of predators such as snakes, lizards, preying birds, human interference, and destruction by the livestock in the area. http://www.aejournal.ir/article_43710_bed4f683c3522342314ad32e55df911c.pdfShil Amayesh Consulting Engineering CompanyJournal of Animal Environment2717-13888420170120First breeding record of Mediterranean Gull (Larus melanocephalus) in IranFirst breeding record of Mediterranean Gull (Larus melanocephalus) in Iran838643715FAMorteza NaderiDepartment of Environmental Sciences, Faculty of Agriculture and Natural Resources, Arak University, ArakMohammad AhmadiDOE BoukanMastoureh DarabiDOEJournal Article20151023For the first time we recorded a breeding colony of Mediterranean Gull <em>Larus melanocephalus</em> fromShahid Kazemi dam, West Azerbaijan, Iran, which is considered first record for the species in Iran.Breeding attempts were monitored in 2014-2015 breeding seasons at Saidabad islet of Shahid Kazemi Dam, where Mediterranean Gulls bred in mixes-species colonies with Slender–billed and Black-headed Gulls. We recorded around 100 Mediterranean Gull nests in Seidabad islet during the two breeding seasons. The modal clutch was three-egg clutches. Nestlings weighed 27 gr (SD=1.64) at hatching and 358 gr (SD=23.5) prior to fledging. Our record in northwest Iran is suggesting that the species is expanding its breeding ranges probably as a result of variation in breeding grounds or climatic changes. Further investigations are needed to understand their breeding ecology and causes and consequences of colony expansions. Compared to a random sample, nests of common Terns, were placed on the higher parts of the island.

This study was conducted to investigate relationship between sperm characteristics including semen volume, percentage of motile sperm, sperm motility, sperm density and spermatocrit with morphological characteristics of male broodstocks of Caspian kutum (<em>Rutilus kutum</em>). Forty males (3-4 years) were randomly selected from the fish captured in the west-southern of the Caspian Sea and their Spermatological parameters (semen volume, sperm density, sperm motility, percentage of motile sperm, and spermatocrit) and some morphological characteristics (weight and fork length) were individually determined. The average weight and fork length of the fish were 758.00±49.20 g and 40.35±3.72 cm, respectively. In addition, each fish had sperm volume of 2.15±0.27 mL with motile percentage of 75.36±8.65%. Sperm motility, sperm density, and spermatocrit were 41.45±3.48 s, 14.93±1.21 ×10<sup>9 </sup>mL<sup>-1</sup>, and 89.75±2.45 %. The results showed that spermatocrit had significantly positive correlation with fork length (0.886) and (0.886) body height of the fish. A significant negative correlation was also obtained between fork length and sperm density (-0.829) showing a decrease of sperm density by increasing fork length in the Caspian kutum. The results of the present research showed that fork length and body height could be used as appropriate indices for identification of sperm density and spermatocrit in Caspian kutum, whereas fish weight had no significant correlation with spermatological parameters.The success of artificial reproduction requires rapid assessment of fish sperm characteristics followed by the ovum.

The objective of the study is to assess the effects of protein and energy levels of diet on fish performance, growth efficiency of Caspian brown trout in order to develop a proper diet for production of this species. Six experimental diets were formulated by replacing casein as a pure protein source with fat as an energy source in the diets according to a 3×2 factorial design. The diet was assigned to 18 tanks with 50 fish each, with three replicated for each diet. The experiment was conducted for 8 weeks with Caspian brown trout with an initial body weight of around 7 g. Caspian brown trout demonstrated a better FCR and a larger SGR at lower protein levels (45 and 50%) in comparison to high protein level (55%; P<0.05). Protein efficiency ratio improved by a decrease in protein content of the diet (P<0.05), but energy content of diets does not affect any growth related parameter such as FCR, SGR and PER (p>0.05). There was also no interaction between protein and energy levels in the growth related parameters, suggesting the effect of protein on the growth parameters in Caspian brown trout did not depend on energy levels of diet. In conclusion diet containing 50% protein can support the maximum growth. High dietary energy level of the diet dose in cooperate in protein sparing effect.A sharp decline in natural population of Caspian brown trout lead to implementing of restocking program in Iran.

Ultrastructure Study of the apical part of the first male gonopods showed that there are differences in the apical part of 6 color morphtypes. what was obtained from this study showed that It is very important to investigate the first male gonopod based on the COI gene in separation of species since, identification of species is difficult for many similarities morphology.http://www.aejournal.ir/article_44514_1105741b9a59ae016ff0c62b76d3e44a.pdfShil Amayesh Consulting Engineering CompanyJournal of Animal Environment2717-13888420170120Study on population diversity of Freshwater Crayfish(Astacus leptodactylus) from Aras dam reservoir using morphometric propertiesStudy on population diversity of Freshwater Crayfish(Astacus leptodactylus) from Aras dam reservoir using morphometric properties21121844519FAMilad PourzareArtemia Research Center, the Research Institute of Fisheries Science countries, organizations, research, education and extension, Urmia, POBox: 365Ramin ManaffarDepartment of Fisheries, Institute for Studies lake, Urmia University, POBox: 1650000-0002-6818-0760Ali Nekuie FardArtemia Research Center, the Research Institute of Fisheries Science countries, organizations, research, education and extension, Urmia, POBox: 365Mehdi Mohamadzadedepartment of biology, faculty of science, Urmia University, UrmiaJournal Article20150924Aras Dam reservoir is a habitat for endemic crayfish which has economically high value among aquatics. The lake behind the dam is one of the important sources of fisheries in the field of aquaculture. Ecological diversity of different areas of the lake has caused several populations of crayfish that live in different parts of the Lake. These ecological divisions may cause phenotypic differentiation among populations. Therefore, the purpose of this study was to evaluate the morphological and morphomeristic features among different populations in 3 different stations in the lake. For this purpose, 72 samples were taken from 3 Stations, and then 27 morphological and 6 morphomeristic factors were examined in the laboratory. The results of this study showed this crustacean population has a certain morphological differences. According to Canonical Discriminat Function Analyses (DA) some of these traits like ABH, CFL-R, CLL-R, CLW-R, CPW, HEW, TEW and α angle are more influenced by ecological circumstance of area.Aras Dam reservoir is a habitat for endemic crayfish which has economically high value among aquatics.

This study was conducted in order to investigate the potential of using Ovaprim (gonadotropin and dopamine antagonist) hormone to induce ovarian maturation on <em>Litopenaeus vannamei</em>. The female broodstocks were divided into 4 treatments as follows: 1) Eyestalk ablation; 2 and 3) Ovaprim injections at 500 and 1000 ng/g body weight (BW), respectively; 4) sterile vehicle solution injection (control). Reproductive parameters were evaluated such as the number of eggs, oocyte diameters and gonadosomatic indices and number of nauplii. The results of the analysis of reproductive factors showed that there was significant difference between experimental treatments (<em>p<</em> 0.05). The highest average number of egg and nauplii (83100± 16993 and 56132± 5180 respectively) was obtained in eyestalk ablation treatment. The weakest reproductive performance was observed in the sterile vehicle solution injection treatment (control).
