Habitat suitability prediction for the animals is one of the ways to achieve the conservation goals for biodiversity. In the present study, habitat suitability of Lacerta Media has been evaluated. Based on the maximum entropy result, northwest and western Iran has been predicted as the most suitable for the species presence. Also there are several records of the species presence in Alborz, Markazi, East Azarbaijan and Esfahan provinces that currently situated outside of the suitable predicted region. Precipitation of the coldest quarter with contribution more than 40% was distinguished as the most contributed environmental variable for species presence. Unsuitability prediction of the species presence in central plateau and East Azarbaijan province directly has been influenced by the recent decreasing of winter precipitation. Also, disturbance the habitats of the species along valleys and rivers is the main factors to the decreasing population size of the species. Finally, evaluation the effective factors for species distribution and finding new suitable areas for species presence can help to prevent the species extinction risk in the wild.

Social responsibility is a transcendent approach that is influenced by the Social impact of individuals or organizations on their peripheral environment and whose main purpose is to create a positive, though small, movement to society. Because today, in addition to the mainstream services, organizations also devote part of their time and resources to community-based activities.The method used in this article is of a practical nature and of descriptive-analytical type.Social responsibility is one of the issues that has been raised by communications experts and UNESCO in the field of press and Media for many years. Accordingly, the Media have the right to criticize and challenge them from different organizations, but they themselves are also responsible for the interests and needs of society, and they must be held accountable, as they mislead public opinion with their mistakes.Media as the most influential cultural institution can effectively and successfully implement the rule of law and fight against the rule of law. The presence of Media in today's world is a sign of freedom of expression and solidity to defend the rights of citizens and citizens, and the sense of responsibility will awaken society and respond to the organizations and the state.

Social trust is the basic capital of each Media and every messenger. In its absence, every thing goes waste and they can not have real presence. The efficiency rate of each Media is evaluated by the difference between nominal and real audiences and the increase of this difference means a defect in one of the pillars messaging, such as message producers, inner essence of the message, message grab (expressive style), situation analysis, mind analysis, transferor analysis, technical and cultural effectiveness of Media and etc. . However the most important item is the Media trust level. Nowadays, rather than just the quantity, the quality of Media is in the spotlight and among the quality elements, the Social trust is the most important.Soft war is a kind of war among Media trust. Those who have this basic capital, are more successful across the world.The research method is documentary. According to research data, Media trust consists of several main characteristics:* sensitiveness: means the subjectivity and vulnerability of this elegant phenomenon. So it can be quickly eliminated.* irreversibility: if, for any reason, such as stigma or labeling, the Media lost its initial trust, it would be, though not impossible, but so difficult to modify. Some emphasis on partial or even conditional reversibility.* Competitiveness: In the situation of information overload (both in producing and transmitting), trust absorption has become a sensitive issue. So the Social trust is not mentioned as an abstract theme, but is definable in competitive environment.

The meta-analysis shows that the most important strengths of research, the diversity of theoretical approaches, the use of the integrated theoretical framework, the diversity of the statistical society, the variety of sample selection methods, the use of various statistical tests, and, at the same time, with high statistical power, attention The level of micro analysis, diversity in the Social Media, and attention to the various impacts in the results section And the weaknesses of the researches, the use of some unrelated theoretical approaches and approaches in theoretical foundations, the weak use of the theoretical frameworks defined in the analysis of the findings, the inability to explain the dimensions of political participation in the theoretical discussions, the overcoming of the proof paradigm And the method of scrolling, the inability to use qualitative and combination methods, the lack of consideration of tool validity, the lack of use of statistical tests to determine the normality of the sample size for measuring parametric tests, the disability in indexing From political participation in the questionnaire and achieving contradictory results in the discussion of the type of effect.

This article is an attempt to investigate the relationship between the student’s use of mass Media and their Social identity and the ratio of their Social capitals. Having reviewed the literature of theoretical and experimental concept of these two factors, the study has adapted the definition of "identity" as proposed by Anthony Giddens and the definition of "Social capital" as proposed by stone and Hughes. The method of the study is survey in which 381 students have been selected randomly among students studying in different courses in states universities of Tabriz in the educational years of 2010 – 2011. The results reveal that the number of the students who have modern Social identity and possessing low and medium Social capital exceeds the number of students who have traditional Social identity and medium and high Social capital. The analysis of data shown in the crosstabs of "Social identity" and" Social capital" illustrates that, the more the students identically get closer to the modernity, the more the ratio of their Social capital decreases and also, traditional students have more Social capital. Urbane students have more institutional Social capital and rural students have more individual Social capital.
