The Impact

The integrated assessment of the ecological state of the main rivers of the lake Baikal basin - Verkhnyaya Angara, Tyya, Barguzin, Selenga, Snezhnaya, Bolshaya Rechka, Khilok, Chikoy is based on the assessment of the variability of the basin system under the influence of two groups of indicators: 1) Direct (immediate) impact - the volume of water intake and wastewater discharge, water use and sequential water supply. Assessment of the impact on the state of the above-listed rivers basins from wastewater was performed using the algorithm proposed by A. Korolev et al. (2007). 2) Indirect (mediate) impact - indicators of areal and linear-network impacts on the catchment area. Based on the calculation of the integral anthropogenic pressure on the territory of the above-listed river basins, only the Selenga river experiences an “average” anthropogenic load. On the territory of most river basins, the anthropogenic load is “lowered” and “low”.

Geomorphological Processes

Mapping of hazardous geomorphological processes in the Baikal Region and its ecological and geomorphological zoning was carried out on the basis of the improved method, developed earlier by the authors. Baikal Region includes the subjects of the Russian Federation in the South Siberia and Republic of Mongolia within the boundaries of the Lake Baikal Basin. The basis of zoning are

The vegetation changes in the area of the Russian part of the Lake Baikal water basin for the period 2010–2018 were investigated using MCD12C1 land cover. The decline in swamp systems area began in 2012 and continued until 2015, after which it partially recovered during the heavy rain season in 2018. During the period of 2010–2018, the area covered by forests did not exceed 20.3% of the Baikal basin of the total portion of the Baikal basin under study. Deforestation began in 2013 and continued until 2017. Over 2013–2018, the forest level decreased by 12.1% compared to the forest state in 2013. The analysis of summer rainfalls and aridity indexes was performed by using CRU TS and GPCC climatic datasets. It is shown that the interannual variations of precipitation and aridity changes are determined by the variability of the global circulation of moist air masses. The MCD64A1 (burned area) and MCD14ML (active fires) MODIS products were used for investigation of the influence of wildfires on vegetation changes. The spatial hotspot distributions and burned areas in general correspond to aridity zones, but they cannot explain the 20-fold increase in the number of wildfires. Most of the hotspot locations are away from settlements, roads, and loggings, in difficult-to-access mountainous areas, as well as in the low-inhabited areas of Siberia. We assume that the nature of such ignitions includes dry thunderstorms, pyrocumulus lightning, or remote impact.

The Noctuidae fauna of Kazakhstan is species-rich and still poorly studied. During a lepidopterological expedition to Almaty Region in the south-eastern part of Kazakhstan, a single female of an unknown Noctuidae species belonging to the subfamily Oncocnemidinae was collected by the senior author of the present paper. The species resembles externally members of the genus Lophoterges Hampson, 1906, especially Lophoterges fatua (Püngeler, 1904), but examination of its genitalia structure revealed that the species is not only undescribed and remarkably different from all known Lophoterges species, but belongs to another genus, Epimecia Guenée, 1839. Up to date, the genus Epimecia was considered as monotypic (Ronkay & Ronkay 1995; Kononenko 2016) and included only Epimecia ustula (Freyer, 1835), which is widely but disjunctively distributed from south-eastern France through the southern Alps, the Balkans, Turkey, Ukraine, southern European part of Russia and western Kazakhstan to southern Ural, north-eastern Kazakhstan and southern Siberia (Ronkay & Ronkay 1995; Kononenko 2016; Titov et al. 2017). The second, peculiar Kazakhstan species of the genus is described below as new.

Close examination of specimens of the Ozothamnus ledifolius species complex (O. ledifolius, O. ericifolius and O. purpurascens) collected throughout Tasmania, Australia, revealed the existence of more taxa than hitherto recognised. An integrative approach employing morphological, genotyping and environmental data of specimens resolved the complex, and showed good support for O. ledifolius and O. ericifolius as currently circumscribed, further clarifying the existence of four additional, distinct taxa: Ozothamnus purpurascens, with revised and clarified typification; O. reflexus comb. & stat. nov., a taxon to which the name O. purpurascens was previously misapplied; O. buchananii spec. nov., a novel taxon from mid–high elevations in north-eastern Tasmania; and O. floribundus spec. nov., a rare and highly localised novel taxon in lowland south-eastern Tasmania.
