Abstract

International audience; Cupressus sempervirens L. is the only native Cupressus in Iran. Basically, the placement of real Mediterranean Forests in the Euro-Siberian vegetation is not expected although its presence in Hyrcanian areas is valuable. In this study; floristic composition, life forms, and chorological spectrum in habitats were analyzed. A total of 700 species belonging to 386 genera from 87 families were recorded. Fabaceae (75), Asteraceae (72), Poaceae (71), and Lamiaceae (46), comprise the largest number of species. 81 species of trees and shrubs grow along with cypress in these areas. Among the recorded life forms, therophytes with 273 species, and hemicryptophytes with 224 species were dominant. More than 85% of the species have at least one Mediterranean or western Iran-Turanian chorotype, which shows a close relationship between cypress growing areas in Iran and the main Mediterranean areas. A total number of 59 species were endemic to Iran. Of these, 31 species (52%) are common with the Irano-Turanian region, 26 species (44%) with the Hyrcanian province, and 2 species (4%) with the Mediterranean region. The results were compared to other studies in the other areas where the cypress does not grow and the cypress grows but outside the Hyrcanian range (Firoozabad, Fars). Our goal is to do a complete floristic and vegetation study in common cypress habitats in Hyrcanian chorion that had imperfections of data. Although these habitats are located within the Hyrcanian chorion, results revealed the floristic composition is not similar to that of the typical Hyrcanian habitats

Abstract

Performance measurement plays an important role in the successful design and reform of regional healthcare management systems. In this study, we propose a hybrid data envelopment analysis (DEA) and game theory model for measuring the performance and productivity in the healthcare centers. The input and output variables associated with the efficiency of the healthcare centers are identified by reviewing the relevant literature, and then used in conjunction with the internal organizational data. The selected indicators and collected data are then weighted and prioritized with the help of experts in the field. A case study is presented to demonstrate the applicability and efficacy of the proposed model. The results reveal useful information and insights on the efficiency levels of the regional healthcare centers in the case study. [ABSTRACT FROM AUTHOR]

Abstract

The genus Alnus has two species in old references of the flora of Iran in which two varieties and one subspecies have been recorded. However, recently, five new taxa have been described and recorded for the flora of Iran. In this study, the herbarium samples were obtained during a widespread sampling from 25 stands, ranged from the most eastern limit of alder dispersion in Golestan to the west of Talish, across the plains and highlands of Hyrcanian forests. After sampling, 28 leaf and female cone morphological traits belonging to 140 alder individuals were measured and analyzed. The results of discriminant analysis showed 11 most important traits in differentiation of the taxa such as leaf angle in apex, blade shape at the base, type of serration, villosity intensity, presence of hairs on the upper surface of leaf and cone shape. In this analysis, 84.3% of recognized individuals were correctly grouped in the related taxon. The maximum disagreement between predicted and recognized groups corresponded to allocation of A. subcordata varieties to villosa and visc versa. Generally, the morphological traits of the two new species including A. dolichocarpa and A. djavanshirii were very similar to that of A. subcordata var. subcordata. While, three subspecies of A. glutinosa were distinguished by the same traits. Finally, the use of DNA barcoding techniques is suggested in order to verify the presence of new taxa in Iran.
