Abstract >>
The research was carried out within the framework of the Flora of Uzbekistan project. In connection with the critical revision of the species of the families Heliotropiaceae and Boraginaceae of the flora of Uzbekistan, the herbarium materials stored in the Herbariums LE, MW, TASH, AA, TAD, NS, NSK, TK, P were studied. Heliotropiaceae is represented by 2 genera and 15 species and the family Boraginaceae by 31 genera and 118 species distributed in 10 tribes. The largest number of species is represented by genera from the tribes Eritrichieae (31) and Cynoglosseae (25). The tribe Lithospermeae (21) is distinguished by the specificity of the species composition. Species of family Heliotropiaceae and small tribes Trichodesmeae (3), Heterocaryinae (6), Myosotideae (9) emphasize the ancient nature of the flora of the republic. Representatives of the tribes Boragineae (8) and Echieae (3) were either introduced in ancient times, naturalized and occupy vast areas, or occupy weedy habitats. When comparing the taxonomic composition of borage in Uzbekistan with the composition of genera and species of the neighboring republics of Central Asia, it was found that the borage flora of Turkmenistan and Tadjikistan is characterized by the closest composition. When analyzing the ranges of all species found on the territory of Uzbekistan, three chorological groups with 14 types of ranges were identified. It is shown that the Iranian-Turanian chorological group determines the specifics of the species composition of borage in Uzbekistan, and the Holarctic chorological group emphasizes the diversity and diversity of both autochthonous and allochthonous representatives of the flora. Ecological analysis shows that landscapes are widely represented in Uzbekistan, found in deserted mountain steppes in black forest, juniper, semi-savannah and shilyak belts at altitudes up to 2500 m. 39 species of borage grow in these communities. On the territory of Uzbekistan, xerophytic and cryoxerophytic lines of evolution were noted in families - 119 species, with a slight participation of mesophytic and cryomesophytic - 14 species. The flora is dominated by biennial monocarpics and ephemera - 70 species and herbaceous polycarpics - 63 species.

Keywords: carpology, halophyte, heterocarpy, morphology, taxonomy, Tripolium vulgare, T. pannonicum

Abstract >>
Tripolium genus is represented by the only species Tripolium pannonicum (Jacq.) Dobrocz. The individuals of this species feature variable morphological characters due to wide distribution area of the species covering vast territory from the Atlantic coast of Europe through the Pacific Ocean. As a typical halophyte, it grows in azonal communities of several latitude zones. The study was based on the analysis of morphological characters which used to be diagnostic in distinguishing between the closely related taxa: T. pannonicum (Jacq.) Dobrocz. subsp. tripolium (L.) Greuter. (T. vulgare s. str.) and T. pannonicum (Jacq.) Dobrocz. subsp. pannonicum. The significance of morphological diagnostic characters in protologs and subsequent botanical literature is discussed. Such morphological characters as presence/absence of heterocarpy and stem branching pattern are stated to be independent of geographical distribution of populations. They rather represent an adaptive character of propagation in annual plants of Tripolium pannonicum (Jacq.) Dobrocz. under variable environmental conditions of under flooding zone.

Keywords: Species distribution modelling, Asia, rare species

Abstract >>
Determining the spatial distribution of rare fungal species is critical to understanding the environmental factors that affect them. Maximum entropy (MaxEnt) spatial distribution modeling solves this problem by allowing inferences about species distribution and ecological resistance from occurrence data. Using this method, we mapped the current and potential geographic distribution of the rare species G. melanocephalum. To establish the regularities in the geographical distribution of the studied species in Siberia, we created its distribution models using Wordclim bioclimatic variables and the MaxEnt software. We modelled the species habitat suitability under current conditions (~1950-2000 AD) and in a future climate (2100 AD) based on 11 records of the species spatial distribution. Most localities of G. melanocephalum in Siberia are 200-500 meters above sea level. The optimal climatic conditions for G. melanocephalum in Siberia are typical of the habitats represented in the Kazakh forest-steppe, South Siberian forest-steppe, and hemiboreal forests of Western Siberia, in the zone of contact between the plains and foothills.

Keywords: geobotanical map, habitat mapping, expert judgment, significance, geobotanical and floristic criteria, EUNIS, Amur region

Abstract >>
The Russian Far East has large areas of natural and semi-natural ecosystems. With the intensification of economic activity, it is necessary here a new look at the environmental policy with a focus on increasing the value of nature and its resources. The work consisted of converting a geo-botanical map into a habitat map. Habitats are presented in categories of significance and value. For all habitats are available floristic, ecological and biotope characteristics. The study area is a part of the Amur-Zeya plain. It is limited by geographical coordinates: 12807 -12823  north latitude and 5125 -5134  east longitude. It is part of the territory of advanced social and economic development Svobodny. The vegetation has been largely modified by humans. There are practically no native plant communities left here (pine, oak-pine, black birch-pine and black birch-oak-pine forests with larch). At present, secondary forest communities (oak, black birch, white birch) and their re-generative series grow here. The flora of the studied area includes 430 species of vascular plants. The list of fungi is represented by 267 species of macromycetes. The plant communities include 20 rare species of vascular plants listed in the Red Books of the Russian Federation (2008) and the Amur Region (2020). Plant communities are the main indicator of habitat, and their boundaries mark habitat boundaries. Habitats were divided into 5 groups: valuable, significant, moderately significant, insignificant and disturbed. In addition, the compliance of biotopes with the European habitat classification EUNIS was taken into account. Valuable habitats occupy 3 % of the total area on the habitat map. They include habitats of particular importance for the protection and the conservation of biological and landscape diversity. The significant habitats occupy 17 % of the total area. They include the Upper Amur forests (pine, oak and oak-black birch forests), mari, swamps and coastal aq-uatic vegetation, which have signs of standard natural communities. Moderately significant habitats account for 22 % of the territory. They belong also to natural communities, but have signs of disturbance. The insignificant habitats occupy 21 % of the total area. Species diversity decreases significantly here. Disturbed habitats occupy the largest areas (37 %).
