Study of the climate variability in the past and present, and correlating those with changes in the distribution range of species has attracted considerable research interest. The genus Ablepharus consists of 10 recognized species, of which A. bivittatus, A. grayanus and A. pannonicus are documented from Iran. In the present study, we modeled with MaxEnt the potential distribution areas and determined the suitable habitats in past （mid-Holocene [MH], and the Last Interglacial [LIG]） and their current distribution for two species of snake-eyed skinks （A. grayanus and A. pannonicus） separately. Models of the species indicated good fit by the average high area under the curve （AUC） values （A. grayanus = 0.929 4- 0.087 and A. pannonicus = 0.979 4- 0.007）. Precipitation of the driest quarter of the year, mean temperature of the coldest quarter of the year, and precipitation of the driest month variables made important contributions to A. grayanus. Two important climate variables contributed importantly to A. pannonicus; temperature seasonality, and mean temperature of the wettest quarter of the year, and one topographic variable, slope. We conclude that these variables form a natural barrier for species dispersal. The MH and the LGM models indicated a larger suitable area than the current distribution.

During extensive field work in the Zagros Mountains, western Iran, from October 2013 to November 2014, twenty five localities in different areas of the Kermanshah Province were investigated. Nineteen specimens of Schmidtler＇s dwarf gecko, Microgecko helenae fasciatus, were collected from six localities in western and southeastern regions of the Kermanshah Province. This new collection verifies the presence of M. h. fasciatus in the area after the description of Schmidtler and Schmidtler of the holotype specimen in 1972. All of the collected specimens are consistent with the described specimens in diagnostic characters, as have a uniform dorsal pattern with five distinct dark crossbars and white posterior margins as well as the higher number of dorsal scales between axilla and groin. Detailed morphology of the new specimens is discussed and compared with those of rare previous records. Taxonomy, distribution, and habitat types of this tiny gecko in the western foothills of the Zagros Mountains are also discussed.

A new subspecies of Laudakia microlepis（Blanford, 1874） is described, from Taftan Mountain in southeastern Iran, based on morphological and genetic characteristics. This new subspecies is distinguished from the nominal subspecies by having a yellowish head along with the following combination of characters： a relatively larger body size; different number of scales around middle of body; larger, weakly keeled, dorsal median scales arranged in 11–13 oblique longitudinal rows; 123–136 scales in a single row from posterior edge of gular fold to vent; 27–31 scales in the first complete whorl around the tail. The type locality of Laudakia microlepis taftanica ssp. nov., is hereby, reported as the Taftan Mountain, about 300 kilometer southeast of the nominal subspecies known range.

The methylammonium lead triiodide(CH_(3)NH_(3)PbI_(3))-based perovskite shows a great alluring prospect in areas of solar cells, lasers, photodetectors, and light emitting diodes owing to their excellent optical and electrical advantages. However,it is very sensitive to the surrounding oxygen and moisture, which limits its development seriously. It is urgent to spare no effort to enhance its optical and electrical stability for further application. In this paper, we synthesize the MAPbI_(3) perovskite film on the glass substrate with/without the ionic liquid(IL) of 1-Butyl-3-methylimidazolium tetrafluoroborate(BMIMBF_(4)) by a simple two-step sequential solution method. The additive of BMIMBF_(4)can improve the quality of crystal structure. Moreover, the photo-luminescence(PL) intensity of MAPbI_(3) film with BMIMBF_(4) is much stronger than the pure MAPbI_(3) film after a week in the air, which is almost ten-fold of the pure one. Meanwhile, under the illumination of 405-nm continuous wave(CW) laser, the fluorescent duration of the MAPbI_(3) film with BMIMBF_(4) is approximately 2.75 min, while the pure MAPbI;film is only about 6 s. In fact, ionic liquid of BMIMBF_(4) in the perovskite film plays a role of passivation, which prevents the dissolution of MAPbI_(3) into CH_(3)NH_(3)and PbI_(2) and thus enhances the stability of environment. In addition, the ionic liquid of BMIMBF;possesses high ionic conductivity, which accelerates the electron transport, so it is beneficial for the perovskite film in the areas of solar cells, photodetectors, and lasers. This interesting experiment provides a promising way to develop the perovskite’s further application.

A new record of Acanthodactylus cantoris from Sistan and Baluchistan in southeastern Iran is presented in this paper,and this lizard is found occurring in the coastal area of the Persian Gulf from Govater to Chabahar. This species is mainly sympatric with A. blanfordi,and their habits and habitats support their close relationship within the cantoris group. In total,29 specimens of A. cantoris(n = 12) and A. blanfordi(n = 17) were compared morphologically using statistical methods. The occurrence of A. cantoris in Iran has been questioned for a long time by different herpetologists,and the distribution,ecology and taxonomy of this newly recorded species were investigated and provided in this paper. An updated identification key for the species of Acanthodactylus in Iran is given.

Based on extensive field work in the northern Zagros Mountains, a new subspecies of Darevskia raddei （Boettger, 1892） from the west Azerbaijan Province, northwestern Iran is described. The new subspecies is distinguishable from all the other three subspecies of D. raddei based on the combination of several distinguishing characters, such as dorsal body with 50-55 oval to round, smooth, or very weakly keeled, scales, 25-31 scales across the gular region, 18-20 femoral pores on each side of body （reaching the knee）, 29-31 tuberculate lamellae under the fourth toe, 11-12 supraciliaries, 9-11 collars and a specific color pattern. The new subspecies meets all the morphological characters described by Eiselt et al. （1993） for an undefined and intermediate form between D. raddei raddei in the east of and D. r vanensis in the west of the distribution range of the species.

We report the combined effects of laser polarization and curvature of the spherical surface on the detached electron spectra from H-. The Theoretical imaging method is used as a tool of investigation. The photodetachment cross sections for various polaxization angles, radii of curvatures and inter ion surface distances axe displayed. The analysis of the spectra reveals that the laser polarization angle θL, curvature of the surface τc and inter ion surface distance d strongly affect oscillations in the spectra. Therefore, a fine control on the laser polaxization and that of curvature in the surface can be used to control oscillations in the photodetachment of negative ions.
