Collembola fauna is less well-known in the northern districts of Iran. This study was conducted to investigate the Collembola fauna in the forests of Mazandaran province, North Iran, during 2016. During this study, 13 genera and 9 species belonging to 6 families were found. The genus <em>Aethiopella</em> Handschin, 1942 and the species <em>Folsomia inoculata</em> Stach, 1947 are reported for the first time from Iran, with the genus <em>Arrhopalites </em>Börner, 1906 recorded for the first time from Mazandaran province.</p> Elliyeh Yahyapour Reza Vafaei Shoushtari Masoumeh Shyanmehr ##submission.copyrightStatement## 2020-09-14 2020-09-14 25 2 10.5281/zenodo.4028689 CONTRIBUTIONS TO THE DOLICHOPODIDAE (DIPTERA) FAUNA OF THE MARMARA REGION OF TURKEY WITH NEW RECORDS <p>Field surveys were carried out in the provinces of Balıkesir, Bilecik, Bursa, Çanakkale, Edirne, İstanbul, İzmit, Kırklareli, Sakarya, Tekirdağ and Yalova in the Marmara region of Turkey between 2009 and 2010. As a result of identification of the collected specimens, 17 genera and 31 species, belonging to Diaphorinae, Dolichopodinae, Hydrophorinae, Rhaphininae, Sciapodinae, Sympycninae, Xanthochlorinae subfamilies, were determined. Two species (<em>Hercostomus plagiatus </em>Loew, 1857 and<em> Poecilobothrus nobilitatus </em>Linnaeus, 1767) are new records for Turkey dolichopodid fauna.</p> Alper Tonguç ##submission.copyrightStatement## 2020-09-14 2020-09-14 25 2 10.5281/zenodo.4028709 THE ABUNDANCE AND DIVERSITY OF GRASSHOPPER (ORTHOPTERA: CAELIFERA) ALONG AN ALTITUDINAL GRADIENT IN JIJEL DISTRICT, ALGERIA <p>Grasshoppers (Orthoptera: Caelifera) diversity were studied in three sites at different altitude in Jijel district (North East Algeria). The insects were captured with sweep net weekly from April to August 2016. It appears that 30 Grasshopper species belonging to 4 families and 11 subfamilies were identified amongst 712 individuals. Acrididae species (25) were the most frequent. The species richness was higher at medium altitude (23 species) and high altitude (22 species) than at low altitude (18 species). Species abundance distribution fitted the Broken stick model at low and high altitude while it fitted the Geometric or Motumura model at medium altitude. Grasshopper abundance increased with the altitude while diversity was not correlated with increasing altitude since diversity indices values were high in medium altitude.</p> Ammar Azil Abdelmadjid Benzehra ##submission.copyrightStatement## 2020-09-14 2020-09-14 25 2 10.5281/zenodo.4028719
