A new cave Pseudoscorpion (Pseudoscorpiones: Chthoniidae): Chthonius (Chthonius) lupinus n.sp. from Bosnia-Herzegovina

A new cavernicolous pseudoscorpion pertaining to the genus Chthonius (Chthonius) C. L. Koch, from Herzegovina (Bosnia-Herzegovina) is erected. Its relations with close congeners are briefly discussed. The new species Chthonius (Chthonius) lupinus n. sp. is an endemic form presently known only from its type locality (Vučija pećina Cave, Mt. Leotar, nr. Trebinje, Herzegovina)

The actual relevance of ecological corridors in nature conservation

The paper considers theoretical and applied foundations of the concept of the ecological corridors in nature conservation. Their relevance comes from recent ecological phenomenon of habitat fragmentation which is rapidly increasing during last decades. Habitat fragmentation is one of the main threats to richness and diversity of wildlife. Ecological corridors can mitigate the loss and fragmentation of habitat. Corridors perform as “bridges” between habitats for species and they provide a flow of the natural or even anthropogenic caused disturbances. In this paper we will present the meaning and significance of ecological corridors in nature conservation, as well as types of ecological corridors and their ecological benefits. Methodological and practical approaches in nature protection system in Serbia are included. [Projekat Ministarstva nauke Republike Srbije, br. 47007 i br. 176008

Roncus ivansticae (Neobisiidae, Pseudoscorpiones): A new epigean species from eastern Serbia

A single species of Roncus L. Koch, 1873, which was collected in eastern Serbia and is new to science (R. ivansticae n. sp.) is described herein; the diagnostic characters are illustrated and their distribution is provided. The possible establishment of two species (or supraspecific?) groups of Roncus is presented briefly in view of the importance of some diagnostic characters

On two new cave species of Pseudoscorpions (Neobisiidae, Pseudoscorpiones) from Herzegovina and Dalmatia

A careful analysis of samples of pseudoscorpions (Neobisiidae, Pseudoscorpiones) from two underground habitats, one near Trebinje (Herzegovina) and the other from the National Park Paklenica (Croatia), has yielded two species of the genus Roncus L. Koch new to science, Roncus tribunus n. sp. and R. argyrunti n. sp. Both new species are described thoroughly, illustrated, and diagnosed. Some biogeographical and evolutionary characteristics of the two taxa are briefly discussed. [Projekat Ministarstva nauke Republike Srbije, br. 173038

Biodiversity of Roncus L. Koch in Montenegro - Roncus teutae n. sp. from Mt. Orjen (Neobisiidae, Pseudoscorpiones)

A single species of Roncus L. Koch, 1873, which was collected in the Baretina Lokva on Mt. Orjen, Montenegro, is new to science (R. teutae n. sp.) and described herein. Its diagnostic characters are illustrated and their distribution is provided. The possible establishment of this species of Roncus is presented briefly in view of the importance and analysis of its diagnostic characters.

A new cave pseudoscorpion from Dalmatia - Microchthonius tragurion n. sp. (Chthoniidae, Pseudoscorpiones)

A new eyeless pseudoscorpion, Microchthonius tragurion n. sp., from a cave in Blizna Donja (near Trogir), from the Jama kod Gomilje Pit, Dalmatia, is described. This new false scorpion differs from all other congeners. There exists a probability that this new taxon is a relict of a tropical fauna incorporating the once northern and tropical area, now representing the subtropical part of the Mediterranean. Morphometric ratios, figures and linear measurements of the new taxon are presented in detail. [Projekat Ministarstva nauke Republike Srbije, br. 173038

A new endemic representative of the genus Rascioduvalius S. B. Ćurčić, Brajković, Mitić & B. P. M. Ćurčić from Mt. Zlatibor, Western Serbia (Trechini, Carabidae, Coleoptera)

A new species of cavernicolous and endemic trechine ground beetles Rascioduvalis zlatiborensis n. sp., is described and diagnosed in the present paper. Also, all important taxonomic features are considered and illustrated. The type specimens of the new species were collected from the Markova (= Ršumska) Pećina Cave, village of Gornji Ljubiš, Mt. Zlatibor, Western Serbia. The new species and its congeners belong to a separate phyletic lineage of Tertiary age. All members of Rascioduvalius S. B. Ćurčić, Brajković, Mitić & B. P. M. Ćurčić are distributed in Western Serbia only, where they have gone through intense differentiation and radiation due to evolution of the karstic relief

A new species of Leonhardia Reitter, 1901 (Coleoptera, Leiodidae, Leptodirini) from Bosnia and Herzegovina, with a key to species of the genus

A new leptodirine leiodid beetle species belonging to the genus Leonhardia Reitter, 1901, L. solaki sp. nov., from a pit in Bosnia and Herzegovina (western Balkan Peninsula) is described and diagnosed. Important morphological features of the new species are listed and photographed. The new species is endemic to the Dinarides of Bosnia and Herzegovina. A key for identification of species and subspecies of the genus Leonhardia is also provided

REMOTE SENSING ROLE IN ENVIRONMENTAL STRESS ANALYSIS: ЕАST SERBIA WILDFIRES CASE STUDY (2007–2017)

Wildfire has been one of the most dangerous environmental stressors nowadays. It is an important disturbance where ecosystem biomass is burned and where organisms are damaged or killed by fire. Therefore, the detecting and monitoring of this stressor are of great importance. During last decades, extensive forest fires have spread in Southern Europe, and they are registered in Serbia as well. During year 2007, several significant fires were registered in Stara Planina and Svrljiške Planine Mountains. The aims of this study were to detect land cover changes for the studied site from 2007–2017, to focus on monitoring the area affected by the wildfire, and to analyse the environment response to stressor. The study area is situated in East Serbia, partially covering the Mountains Stara Planina (western part) and Svrljiške planine (eastern part). The remote sensing techniques were used in the analysis and main satellite data were obtained via USGS Earth Explorer application. Six different classes were selected: Water, Forest, Pastures, Artificial area, Agriculture, and Bare soil. Results showed significant changes in two classes, Forest, and Pastures — the forest spread for more than 20% at the expense of pasture, which decreased more than 23%
