We studied the contemporary species diversity of the vertebrate animals inhabiting the southern part of the Aral Sea area. The terrestrial vertebrates of the region comprise 33 reptilian, 317 avian and 67 mammalian species. We determined the influence of the Aral Sea’s shrinkage on the local fauna and the long-term changes in the populations and life cycles of the animal species common for the region.

Morphogenesis of 10 species of ephemerals from 4 families (Asteraceae, Brassicaceae, Fabaceae, Chenopodiaceae) in the natural habitats of the Kyzylkum desert and in sowing in Tashkent in the experimental plot was studied. The features of morphogenesis are revealed: prolonged preservation of cotyledons, predominance of rosette form of growth in the juvenile stage, heterophyllia, reduction of vegetative mass under stress conditions, morphological lability.

This investigation was carried with the aims of studying the relationships between marital satisfaction and relationship beliefs of married students in masters studying at Azad University of Ayatollah Amoli. The selected sample size consisted of 130 female and 197 male students made available by applying sampling method. The present method of study is retrospective correlational design; in order to collect data, Eidelson’s and Epstein enrich marital satisfaction and communication beliefs questionnaire was applied. Also, the obtained data was analysed by application of Pearson's correlation coefficient and multiple regression analysis by SPSS statistical software. The results indicated that marital satisfaction variable and irrational beliefs variable communication have negative significant relationship (p<0.01). In view of the obtained data in this research and in order to increase the rate of marital satisfaction and also to change and adjust communication beliefs, the outcome is presented with few recommendations for the purpose of emotional divorce decreases.

The present study was conducted to investigate the effectiveness of life skills' training on mental health promotion of visually impaired and blind students. This is a quasi-experimental study with pre- test, post- test and control group. The study sample consisted of 30 visually impaired and blind students in Khorramabad who were selected by available sampling. The subjects were randomly divided into two experimental (n = 15) and control (n = 15) groups. Individuals in the experimental group received life skills' training in 10 sessions of 45 minutes. In order to collect data, a clinical interview and General health question (GHQ) were used. Data collected were analyzed using multivariate analysis of variance. According to the results, a significant relationship is found between teaching life skills and promoting mental health of visually impaired and blind students.

Sind sardinella (Sardinella sindensis) is one of the most important small pelagic species exploited by the Iranian fisheries from east (Jask) to West (Gorzeh). In order to study the discrimination of sind sardinella populations in three fishing grounds (Gorzeh, Qeshm and Jask) 360 specimens were collected during April-May 2011. After collecting otolith specimens, size and weight parameters including overall length, standard length,fork length, area and primeter were measured and registered. Otolith shape parameters such as roundness, elasticity, circularity and rectangularity were described and determined by using otolith size. The results of the present study indicated that size and weight parameters of left and right otolith showed no significant difference. Also, no significant differences were found between otolith shape parameters in both male and female samples. Discriminant function analysis was performed to examine the segregation of stocks as well as grouping /classification of similar locations / stations. The results demonstrated that the population of sind sardinella was not significantly different in three fishing grounds. Therefore, can be considered as the same stock However, the results of otolith analyses indicated that there was a significant difference in roundness indices in Qeshm and Gorzeh according to T-test. Besides.the ellipticity of otolith shape in Gorzeh is significantly different that from that of Qeshm and Jask(P<0/05). Also, discriminant function analysis among indices of otolith shape demonstrated that no difference was found between otolith indices in mentioned fishing grounds. It can be stated that sind sardinella population in Jask, Qeshm and Gorzeh belong to the same stock.
