The bumblebee fauna of the Southern Taymyr region, northern Siberia, is represented by 10 species, i.e., Bombus consobrinus, B. flavidus, B. lapponicus, B. hypnorum, B. jonellus, B. cingulatus, B. balteatus, B. pyrrhopygus, B. hyperboreus, and B. cryptarum. During the field research for this study, 7 species of bumblebee on the Putorana Plateau (or the Putorana Mountains, on the northwestern edge of the Central Siberian Plateau) and 6 species near Dudinka Town were observed and B. consobrinus was found for the first time on the Putorana Plateau. To date, B. consobrinus was known only in the southern and central parts of the Krasnoyarsk Krai. Regarding the regional fauna, Transpalaearctic and Holarctic species are presented. According to the latitudinal aspect, in this region there are arcto-boreal, arcto-temperate, boreal and temperate species. An analysis of the community was carried out regarding bumblebees that live on the Putorana Plateau. It was found that species of the subgenus Pyrobombus and Alpinobombus, that are typical for the tundra and forest-tundra zones in the Northern Palaearctic, are dominant within the bumblebee community.

Jurasaidae are a family of neotenic elateroid beetles which was described recently from the Brazilian Atlantic Forest biodiversity hotspot based on three species in two genera. All life stages live in the soil, including the larviform females, and only adult males are able to fly. Here, we report the discovery of two new species, Jurasai miraculum sp. nov. and J. vanini sp. nov., and a new, morphologically remarkable population of J. digitusdei Rosa et al., 2020. Our discovery sheds further light on the diversity and biogeography of the group. Most species of Jurasaidae are known from the rainforest remnants of the Atlantic Forest, but here for the first time we report a jurasaid species from the relatively drier Atlantic Forest/Caatinga transitional zone. Considering our recent findings, minute body size and cryptic lifestyle of all jurasaids, together with potentially high numbers of yet undescribed species of this family from the Atlantic Forest and possibly also other surrounding ecoregions, we call for both field research in potentially suitable localities as well as for a detailed investigation of a massive amount of already collected but still unprocessed materials deposited in a number of Brazilian institutes, laboratories and collections.

The goal of this research is to prioritize effective factors on motivating employees to keep on working and determining the most important effective factors on the employees' motivation. In this paper, to grade effective factors on the employees' motivation for keeping on to work, the Fuzzy AHP method, which is one of the multi-standard decision-making methods was utilized. Field research and library research methods were used for collecting the needed information.  Results indicated that among the effective factors on the employees' motivation for job persistence, the health factor is the most important and financial status is the second most important factor. The least importance is given to the significance of the work for that person. In this paper, the effective factors on the employees' motivation for job persistence were rated for the first time. Results of this research are very useful in devising strategies that are related to keeping employees for the human resources' executives. The results of this paper are not applicable to all organizations. Furthermore, in this research, only the factors with positive impacts on employees for job persistence were rated.

The Karatag gorge is one of the natural areas where valuable genetic resources (wild, fruit and many valuable species) are preserved. A characteristic feature of the region is the richness of the diversity of flora and vegetation, where the main formations of Tajik vegetation are noted (maple, hazel, almond, frame, juniper). The article summarizes the results of the authors’ field research on the study of the state of xerophilic forests in the Karatag gorge. For the first time, the authors cite original materials on the phytocenology of all formations of this type of composition. According to the results of our research, the Shibleak communities in the study area are distributed in high-altitude belts from low-hilly 600–800 m to middle mountains 800–1800, 2000 m. The main formations of this type in the study area are: Acer regelii, Crataegus pontica, Celtis caucasic, Pistacia vera, Amygdalis bucharica, Ampelopsis vitifolia, Atraphaxis pyrifolia. As a result of the study, 340 plant species, 6 formations and more than 25 vegetation associations were identified in the composition of the flora of this type of the study area.

The antlions (Myrmeleontidae) of Cyprus have been poorly studied and only 13 species were known from this biogeographically interesting island. In light of new field research, we provide an updated checklist to the Cypriot antlions, including seven species reported for the first time from the island. Of these, the findings of the Middle Eastern species Distoleon laticollis and Cueta kasyi are particularly noteworthy. The Cypriot antlion fauna appears dominated by widespread Mediterranean elements, with relatively few Middle Eastern and endemic species.

AbstractThe Palearctic staphylinid beetles of the subfamily Aleocharinae occuring in North America are discussed. The record of Meotica exilis (Knoch) is regarded doubtful. The records of seven species doubtfully reported from North America are confirmed: Atheta amicula (Stephens), A. coriaria (Kraatz), A. fungi (Gravenhorst), A. islandica (Kraatz), A. pallidicornis (Thomson), A. palustris (Kiesenwetter) and Dinaraea angustula (Gyllenhal). Nine Palearctic species are recorded for the first time from North America: Atheta botanicarum Muona, A. dilutipennis (Motschulsky), A. harwoodi Williams, A. longicornis (Gravenhorst), A. nigricornis (Thomson), Geostiba circellaris (Gravenhorst), Gnypeta caerulea (C. R. Sahlberg), Dochmonota rudiventris (Eppelsheim) and Meotica apicalis G. Benick. The genera Homia Blackwelder and Schistoglossa Kraatz are occuring in North America. Pragensiella Machulka, 1941 is regarded a junior subjective synonym of Thecturota Casey, 1893. By the 16 species added here the number of Holarctic species of Aleocharinae amounts to 32.

This paper presents a refined belemnite based biostratigraphy for the Bajocian-Bathonian transition in the Yuryung-Tumus peninsula (northern Siberia, Russia). A revision of the Siberian belemnite zonation is proposed. Herein two new belemnite biostratigraphic units are introduced: the Paramegateuthis subishmensis Zone (upper part of the Lower Bajocian) and the Paramegateuthis ishmensis Zone (Lower-Middle Bathonian boundary interval). Paramegateuthis subishmensis STOYANOVA-VERGILOVA, recorded for the first time in Siberia and previously only known from Bulgaria (Sub-Mediterranean domain), provides evidence for correlation of both the Boreal Boreiocephalites borealis and Cranocephalites gracilis ammonite zones with the standard Stephanoceras humphriesianum Zone. The new biostratigraphic data also result in an improved correlation based on belemnites for the Lower-Middle Bathonian of the Boreal (Siberia, North European Russia) and Subboreal (Central Russia) regions.

The paper analyzes the salinity dynamics in the Sivash Bay after the closure of the NorthCrimean based on the data from field research carried out by MHI RAS in 2014–2020. Recent field data are compared with the literature data obtained in the period before the commissioning of the North Crimean Canal. Salinity in water samples taken during 18 expeditions to the Eastern and Southern Sivash at over 100 stations was determined using the refractometric method. It was shown that after the closure of the North Crimean Canal in 2014, there was a steep increase in salinity in the Eastern and Southern Sivash. It was determined that in the area of the Sivash Bay, the haline field changes non-uniformly. The data analysis showed that salinity increases from north to south (from the Eastern to Southern Sivash), moreover salinity values in the Southern Sivash can be several times higher than those in the Eastern Sivash. In spring 2014, salinity in the Eastern Sivash varied from 27 to 33 ‰, and in 2020, 6 years after the closure of the Canal, salinity increased significantly at all stations reaching 60–70 ‰. These values are comparable to those obtained before the start of the Canal in the 1950s. The highest salinity values were observed in the South Sivash: in 2013, it was 54 ‰ and in summer 2020, for the first time since the North Crimean Canal became operational, it reached 110 ‰, which almost corresponds to the salinity level observed in 1969.
