Modeling the potential distribution areas for a given species is important in understanding the relationship between the actual distribution and the most suitable habitat for a species. In this study, we obtained all available records of Trapelus ruderatus and Trapelus persicus from museums, literature and fieldwork and used them with environmental layers in the Maximum Entropy algorithm to predict highly suitable habitat areas. The distribution model of T. ruderatus and T. persicus showed excellent performance for both models （T. ruderatus AUC = 0.964 ± 0.001 and T. persicus AUC = 0.996 ± 0.003）, and predicted suitable regions in Iran, Turkey, Iraq and Syria. Niche overlap was measured between the two groups by ENMtools and 13% overlapped. We used a niche identity test to determine differences between the niches of the two species. Finally, by comparing our null hypothesis to the true niche overlap of the two species, we were able to reject our null hypothesis of no difference between the niches. Due to the sympatric distribution pattern of these species, we do not need a background test for niche divergence.

Predictive potential distribution modeling is of increasing importance in modern herpetological studies and determination of environmental and conservation priorities. In this article we provided results of analysis and forecasts of the potential distribution of smallscaled rock agama Paralaudakia microlepis （Blanford, 1874） using the distribution models through Maxent （***/- schapire / maxent）. We made an attempt for comparison of input of bioclimatic factors and characteristics of biotope distribution for three species of genus Paralaudalda. Constructed model identified dissemination of Paralaudakia microlepis enough performance （AUC = 0.972 with dispersion 0.003）. According to the map constructed, the most suitable habitats of smallscaled rock agama Paralaudakia microlepis are located in southern and eastern Iran, the west of central Pakistan and southeastern Afghanistan.

Predictive potential distribution modeling is crucial in outlining habitat usage and establishing conservation management priorities. In this paper we provide detailed data on the distribution of the Caucasian rock agama Para- laudakia caucasia, and use species distribution models （MAXENT） to evaluate environmental suitability and potential distribution at a broad spatial scale. Locality data on the distribution of P. caucasia have been gathered over nearly its entire range by various authors from field surveys. The distribution model ofP caucasia showed good performance （AUC = 0.887）, and predicted high suitability in regions mainly located in Tajikistan, north Pakistan, Afghanistan, southeast Turkmenistan, northeast Iran along the Elburz mountains, Transcaueasus （Azerbajan, Armenia, Georgia）, northeastern Turkey and northward along the Caspian Sea coast in Daghestan, Russia. The identification of suitable areas for this species will help to assess conservation status of the species, and to set up management programs.

This study investigated physical,chemical and lipid oxidative properties of emulsion gels(W/O)incorporating Jerusalem artichoke(JA)*** purified inulin extract(PPIE,1%)improved the homogeneity of emulsion gel(with no syneresis)and developed smaller particle size droplets(average 40μm)than control(average size 60μm).HPLC revealed that PPIE had 80.28%inulin content compared with commercial inulin(CI,100%).Crude inulin extract(CIE,0.08–0.33 mg/mL)delayed linoleic acid oxidation because of higher total phenolic content(4.96±0.01,mg GAE/g),compared with PPIE(0.72±0.03).Lipid oxidative stability of emulsion gels with inulin samples was in the order of CI>PPIE>CIE(P<0.05)by Rancimat analysis,which agreed with volumetric gel index *** study suggests that emulsion gels with JA inulin(PPIE)could act as a potential fat replacement in food systems.

This study aims to find appropriate locations for wind farms that can maximize the overall energy output while controlling the effects of wind speed *** wind speeds are required to obtain the maximum possible power output of a wind farm. However, balancing the wind energy supplies over time by selecting diverse locations is necessary. These issues are addressed using network-based models. Hence, actual wind speed data are utilized to demonstrate the advantages of the proposed approach.
