Abstract
Based on all collected literature dealing with the fauna of springtails in Vojvodina Province (Republic of Serbia), a list of species was created and taxonomically revised according to the latest system of Collembola taxonomy. In total, the check list of springtails of Vojvodina includes 125 species in 58 genera from 16 families and 3 orders. The most abundant order is Entomobryomorpha (55%), followed by Poduromorpha (24%) and Symphypleona (21%). According to the general distribution of the species themselves, the presented list has the following composition: 27.2% of the recorded species are European, the same number are Palearctic, 24% of the species on the list are Holarctic, 18.4% are cosmopolitan, and 3.2% are endemic to Serbia (mostly related to type localities). The species Drepanura deliblatica Loksa & Bogojević, 1970, Sinella jugoslavica Loksa & Bogojević, 1970, Deuterosminthurus quadrangulatus (Loksa & Bogojevic, 1970) and Fasciosminthurus angulipunctatus (Loksa & Bogojevic, 1970) are strictly protected species in the Republic of Serbia. This paper is a contribution to the knowledge of the Collembola fauna of Europe and represents a step towards the formation of a checklist of springtails of the Republic of Serbia.

Abstract
We aim in this study to increase our knowledge of the Odonata in the Aures, an unexplored region of northeastern Algeria, using single-species occupancy model (spOccupancy R package) coupled with spatial interpolation technique (kriging ArcGis) to assess the relationships between elevation and odonatan species distribution. From time windows of about 90 days (June to August 2021), a total of 22 odonatan species belonging to 2 suborders (Anisoptera and Zygoptera) have been recorded in 15 sampling wet biotopes; among them the endangered Calopteryx exul. Our modelling shows that 62% of the odonatological community has a uniform probability of being present in the studied area. The probability of detecting a species is similar during each survey for 90% of the odonatological community except for the endangered Calopteryx exul (p ˂ 0.05) and Crocothemis erythraea (p ˂ 0.05). We also found that Ischnura graellsii and I. saharensis are the most common species; they are predicted to occur in more than 60% of sites, followed by Anax imperator, Orthetrum chrysostigma, and Platycnemis subdilatata, where they occur in about 50% of the wet biotopes sampled. Finally, our modelling revealed no evidence for a significant altitudinal variation (500 to 1900 meters above sea level) impact on both occupancy and detectability of the majority of the odonatan species, except for Crocothemis erythraea and Sympetrum fonscolombii. The kriging interpolation indicates that they are concentrated within the altitude range of 400 m to 1000 m.
