Abstract :
Background and Objective: Environmental factors affecting the species are one of the most important topics in the science of ecology and understanding the influences of environmental variables can help the protection of species especially endangered species. The purpose of this study was to identify habitat factors influencing the presence of lizard habitat in Alvand protected area. Method: Alvand protected area; with 8618 hectares survey is located in central province and Khomein city. In this paper, the studied area, in terms of geomorphology is divided to three types including, plain, hillside and mountainous area. Then all three type of habitats divided to cells with 5050 size in Arc GIs 9.3, and ultimately 10 percent of these cells are selected randomly and will be considered and analyzed Findings: The results of GGE biplot software for three groups of habitat plains, foothills, and mountainside showed that the most presence in plains habitat is dependent to Ophisops elegans species that variables which influence the presence of these species are: the richness of vegetation, soil content, and the density of the vegetation and grit is the worst parameter for the presence of this species. In mountainside habitat, the most presence is dependent to the species Ophisops elegans and Paraloudakia Caucasia. And the most important parameter for Paraloudakia Caucasia is height and the percent of grift. Also for mountainside habitat species like Ophisops elegans, Paraloudakia Caucasia and Loudakia nupta had the most presence. Discussion and Conclusion: Results obtained from this study illustrated that especially Ophisops elegans and Paraloudakia Caucasia species with percent of rock and Loudakia nupta with vegitation enrichment, the density of vegetation, the percent of grit, and height, respectively showed presence.
