The Elachistidae material collected during the joint Soviet-Finnish entomological expeditions to the Altai mountains, Baikal region and Tianshan mountains of the previous USSR is listed. Previous literature dealing with the Elachistidae in Central Asia is reviewed. A total of 40 species are dealt with, including descriptions of five new species: Stephensia jalmarella sp. n. (Altai), Elachista baikalica sp. n. (Baikal), E. talgarella sp. n. (southern Kazakhstan), E. esmeralda sp. n. (southern Kazakhstan) and E. filicornella sp. n. (southern Kazakhstan). The previously unknown females of E. bimaculata Parenti, 1981 and Biselachista zonulae Sruoga, 1992 are described.

Tectonic activity in an area could result in various impacts such as changes in elevation, level of slope percentages, river flow patterns and systems, and the formation of geological structures both locally and regionally, which will form a new landscape. The tectonic activity also affects the stratigraphic sequences of the area. Therefore, it is necessary to study morphotectonic or landscape forms that are influenced by active tectonic activities, both those occur recently and in the past. These geological results help provide information of the potential of natural resources in and around Tanjung Bungo area. Morphological data are based on three main aspects including morphogenesis, morphometry, and morphography. The data are collected in two ways, the first is field survey by directly observing and taking field data such as measuring geological structures, rock positions, and outcrop profiles. The second way is to interpret them through Digital Elevation Model (DEM) and aerial photographs by analyzing river flow patterns and lineament analysis. The field measurement data are processed using WinTensor, Dips, and SedLog Software. The supporting data such as Topographic Maps, Morphological Elevation Maps, Slope Maps, Flow Pattern Maps, and Lineament Maps are based on DEM data and are processed using ArcGis Software 10.6.1 and PCI Geomatica. Morphotectonically, the Tanjung Bungo area is at a moderate to high-class level of tectonic activity taken place actively resulted in several joints, faults, and folds. The formation of geological structures has affected the morphological conditions of the area as seen from the development of steep slopes, structural flow patterns such as radial, rectangular, and dendritic, as well as illustrated by rough surface relief in Tanjung Bungo area. This area has the potential for oil and gas resources as indicated by the Telisa Formation, consisting of calcareous silts rich in planktonic and benthonic fossils, which may be source rocks and its contact with the Menggala Formation which is braided river system deposits that could be good reservoirs. Further research needs to be done since current research is only an interpretation of surface data. Current natural resources being exploited in Tanjung Bungo region are coals. The coals have thicknesses of 5-7 cm and are classified as bituminous coals.

Until recently only two species of Gyalideopsis (G. piceicola and G. alnicola) were known from very few localities in Russia. Gyalideopsis helvetica is reported for the first time for Russia from the southern part of Baikal area (KhamarDaban Range, Baikalsky Zapovednik). Description of the collected specimen and its comparison with the literature data are provided; morphology, ecology and distribution of G. helvetica are discussed. The hyphophores of G. helvetica are recorded and described for the first time. An identification key to Gyalideopsis species known in Russia is provided.

This article focuses on the location of brown-headedtit (Parus montanus CONRAD VON BALDENSTEIN, 1827) on the territory southern Baikal region. The article presents literature data on the intra-landscape placement of chubby tit and gives a complete description of areas suitable for the habitat of these birds.

В статье проводится обобщение сведений о поэтапном заселении байкальского региона, и вводятся в научный оборот ранее нигде не упоминавшиеся источники, свидетельствующие о мирной колонизации края русскими, а также о проживании русских в Сибири, за долго до похода Ермака. Как новый метод исследования применяется анализ художественной фотографии, как этнокультурного источника. В работе также ставится под сомнение вопрос о происхождении сибирского казачества.The article summarizes the information about the gradual settlement of the Baikal region, and introduced into scientific circulation previously never mentioned sources, indicating the peaceful colonization of the region by the Russians, as well as the Russian residence in Siberia, long before the campaign of Ermak. The analysis of art photography as an ethno-cultural source is used as a new method of research. The paper also questions the origin of the Siberian Cossacks.
