History Of

The article examines the main publications covering the centuries-old history of the Catholic Church in the lands of modern Bashkortostan, as well as partly affecting the interaction of local Catholic communities with coreligionists from other cities located in the South Urals, as well as in the Middle Volga region. Unfortunately, there are quite a few special studies on the history of this Christian denomination in our republic. Many works, in one way or another related to this issue, are of a general nature and contain a schematic listing of factual information, or are more devoted to the history of national communities, for which this religion is, to a certain extent, one of the most important elements of traditional ethnic culture. Here it is necessary to note, first of all, publications on the history of the Polish and German diaspora, which provide information about the participation of representatives of these communities in the creation of Catholic parishes and public associations associated with charity and education. At the same time, the significance of the confessional aspect is to a much lesser extent revealed in works on the history of Latvian immigrants from Latgale, Belarusians and Ukrainians from Volyn and Eastern Galicia, who, due to various circumstances, left their homes during the First World War, as well as other Catholic emigrants from Central and Western Europe, located in the Ufa province at the beginning of the XX century. In some articles on demography and striking features of social stratification, one can find indirect references to the presence of Catholics, but this information only It is noteworthy that most publications indicate the middle of the 17th century as the earliest dating of the appearance of believing Catholics in the South Urals, and evidence of missionary trips to the Eastern Hungarians during the 13th-15th centuries allows us to make hypothetical assumptions about their role in the life of the local religious community. It can be noted that the presence of a certain part of Catholics on the territory of Bashkiria during the 16th20th centuries. was associated with forced migration due to the fact that, as a result of military clashes, some of them were captured, as well as due to participation in activities that conflicted with the interests of the Russian leadership are considered, with a few exceptions, only in the context of the problem of the origin of the Bashkir people, most likely due to the modest results of the preaching.

The synthaxonomy and ecology of communities with predominance of Hordeum jubatum L., included in the «black list» of the Republic of Bashkortostan (Abramova, Golovanov, 2016a), the preliminary «black list» of the Orenburg Region (Abramova et al., 2017) and the «Black book of flora of Middle Russia» (Vinogradova et al., 2010), are discussed in the article, which continues a series of publications on the classification of communities with alien species in the South Urals (Abramova, 2011, 2016; Abramova, Golovanov, 2016b). H. jubatum was first found in the South Urals in 1984 as an adventive plant occurring along streets in the town of Beloretsk, as well as in gardens where it was grown as an ornamental plant. During the 1980s, it was met also at some railway stations and in several rural localities. Its active distribution throughout the South Urals started in XXI century (Muldashev et al., 2017). Currently, H. jubatum, most naturalized in the native salted habitats of the steppe zone, is often found in disturbed habitats in all natural zones within the region. The short vegetating period and resistance to drought allowed it to be naturalized also in dry steppes, where it increasingly acts as the main weed on broken pastures. The aim of the work, conducted during 2011–2017, was further finding the centers of H. jubatum invasion in 3 regions adjacent to the South Urals — the Republic of Bashkortostan and the Chelyabinsk and Orenburg Regions (Fig. 1). In the main sites of H. jubatum invasion 71 relevès were performed on 10–100 m² sample plots with the information of location, date, the plot size, the total cover, average and maximum height of herb layer. Classification was carried out following the Braun-Blanquet method (Braun-Blanquet, 1964) with using the Kopecký–Hejný approach (Kopecký, Hejný, 1974). The community ecology was assessed by weighted average values according to the optimal ecological scales by E. Landolt with usfge of the software of IBIS (Zverev, 2007). PCA-ordination method with usage CANOCO 4.5 software package was applied to identify patterns of environmental differentiation of invasive communities. The current wide distribution area of H. jubatum and its naturalization in synanthropic, meadow and saline communities in the South Urals, as well as its occurrence within mountain-forest belt, forest-steppe and steppe zones both in the Cis- and Trans-Urals, indicates species wide ecological amplitude, high adaptive capability and invasive potential. Its vast thickets are known in the steppe zone, both in disturbed steppes around settlements and along the banks of water bodies. The invasion sites are smaller in the northern regions and mountain forest belt, where these are located in settlements or along communication lines. Therefore, the steppe zone is more favorable for invasive populations, and their distribution will continue from the south to the north. Communities with predominance of H. jubatum, described earlier (Abramova, Golovanov, 2016b) in the Cis-Urals as two derivative communities (associations Hordeum jubatum [Scorzonero–Juncetea gerardii], Hordeum jubatum [Artemisietea]) and Polygono avicularis–Hordeetum jubati, were met in other regions of the South Urals. Also a new derivative community Hordeum jubatum–Poa pratensis [Cynosurion cristati], occuring in the northern part of the Cis-Urals and Trans-Urals, was established. In new habitats this species forms three types of communities: ass. Polygono avicularis–Hordeetum jubati (Fig. 2) the most widespread in anthropogenic habitats throughout the South Urals; derivative community Hordeum jubatum–Juncus gerardii [Scorzonero–Juncetalia gerardii] (Fig. 5) which replaces saline meadows mainly in the steppe zone of the region; derivative community Hordeum jubatum–Poa pratensis [Cynosurion cristati] (Fig. 4) which y replaces low-herb meadows in the forest-steppe zone and mountain-forest belt. PCA ordination (Fig. 6) shows that moisture (H) and soil richness-salinization (S) factors are in priority in differentiation of communities with predominance H. jubatum. The first axis is mainly related to the salinization and soil richness. The community pattern along the second axis is associated with wetting factor. The cenoses of the derivative community Hordeum jubatum–Poa pratensis [Cynosurion cristati] (less salted substrates in drier conditions in the northern part of the forest-steppe zone and the mountain forest belt) are grouped in the upper part of the ordination diagram, while communities of ass. Polygono avicularis–Hordeetum jubati (drier conditions in settlements, the steppe zone) in its low left part. Thus, axis 1 also reflects the intensity of trampling. Another group is formed by cenoses of the derivate community Hordeum jubatum–Juncus gerardii [Scorzonero–Juncetalia gerardii], (salt substrates with a high level of moisturization, on not very damaged water body banks). All communities with H. jubatum are well differentiated in the space of the main ordination axes that indirectly confirms the correctness of our syntaxonomic decision. Undoubted is further expansion of H. jubatum with its entering both anthropogenic and natural plant communities within the South Urals that suggests a constant monitoring in centers of species invasion.

Segetal, or weed, communities are the stands of the weed plant species which are formed under the influence of edafo-climatic conditions and the mode of soil disturbance within the processing of crop rotation (agrotechnical factor) (Mirkin, Naumova, 2012). This paper is the second part of weed community study in the South Ural, assigned to the class Papaveretea rhoeadis S. Brullo et al. 2001, syntaxon unites the weed communities of winter cereals with two orders: Aperetalia spica-venti J. Tx. et Tx. in Malato-Beliz et al. 1960 and Papaveretalia rhoeadis Hüppe et Hofmeister ex Theurillat et al. 1995; and three alliances (Khasanova et al., 2018). Data on diversity, floristic, ecological and spatial differentiation of mesoxeric and xeric weed communities of the alliances Caucalidion Tx. ex von Rochow 1951 and Lactucion tataricae Rudakov in Mirkin et al. 1985 in steppe and southern part of the forest-steppe zones are given (Table 1; Fig. 1). The dataset contains 756 relevés: 647 made by authors during the field seasons of 2002–2018, while 109 taken from published monography (Mirkin et al., 1985). The alliance Caucalidion combines weed communities on rich carbonate chernozem soils in the forest-steppe zone. Diagnostic species are Galeopsis bifida, G. ladanum, Galium aparine, Erodium cicutarium, Persicaria lapathifolia, Silene noctiflora, Thlaspi arvense. This alliance occupies the central position within class between communities of forest zone of the alliance Scleranthion annui and these of the steppe zone of the alliance Lactucion tataricae. The last alliance combines weed communities of the steppe zone and southern part of the forest-steppe one on south and typical chernozem soils. Two species are diagnostic: Lactuca tatarica and Panicum miliaceum. Alliances are differentiated in sample plot species richness and coenoflora: 145 species in alliance Caucalidion coenoflora (mean species number per plot is 16), and 207 species in that of Lactucion tataricae (consequently 13 species). There are 8 associations, 4 subassociations, 6 variants, 1 unrank community within these two alliances, among which 5 associations and all subassociations are new. The alliance Caucalidion includes 4 associations with spatiall and crop differentiation, which are mainly character for the forest-steppe part of the Trans-Urals within the bounds of forest-steppe region of the eastern slope of the Southern Urals. Two associations are new: Cannabio ruderalis–Galeopsietum ladani ass. nov. hoc loco (Table 2; holotypus hoc loco — rele­vé 7) unites weed communities of winter, less often — spring crops; Lycopsio arvensis–Camelinetum microcarpae ass. nov. hoc loco (Table 4; holotypus hoc loco — relevé 3) unites weed communities of row crops, mainly sunflower, less often — cereals. In the same area the communities of the ass. Cannabio ruderalis–Sinapietum arvensis Rudakov in Mirkin et al. 1985 (Table 3) unite the weed communities of mainly winter cereals — wheat and rye. These communities, described in 1980s, previously were widespread in the Trans-Urals (Mirkin et al., 1985), while now occur locally in the northern part of this area. The communities of ass. Centaureo cyani–Stachyetum annuae Abramova in Mirkin et al. 1985, also described in the 1980s, were not found in the 2010s. The diversity of the most xerophytic alliance Lactucion tataricae is represented by 4 associations which occur both in the Trans-Urals and the Cis-Urals. The most common in the last area are weed row crops (beet, nute, flax, sunflower, corn, peas, buckwheat) communities of the ass. Echinochloo crusgalli–Panicetum miliacei ass. nov. hoc loco (Table 5; holotypus hoc loco — relevé 5. They are common in five natural districts: Predbelskiy forest-steppe one, forest and fo­rest-steppe of Belebey Upland, Cis-Urals steppe one, forest and forest-steppe one on Zilair Plateu, and Zabelskiy district of the broad-leaved forests. The weed communities of spring and winter cereals of the ass. Lathyro tuberosi–Convolvuletum arvensis ass. nov. hoc loco (Table 6; holotypus hoc loco — relevé 5) are common only within the Cis-Urals steppe district. The communities of ass. Lactuco serriolae–Tripleurospermetum inodori ass. nov. hoc loco (Table 7; holotypus hoc loco — relevé 2) which unites the weed communities of winter cereals, are common in the steppe zone and the southern part of the forest steppe one of the Trans-Urals and the Cis-Urals within the Cis-Urals steppe, Trans-Urals steppe, and Predbelskiy forest-steppe districts. The communities of the ass. Lactucetum tataricae Rudakov in Mirkin et al. 1985 are associated exclusively with the steppe zone of the Trans-Urals. The Lactuca tatarica community (Table 8), distributed in the steppe and southern part of the forest steppe zones of the Trans-Urals, probably is derived from the ass. Lactucetum tataricae under the intensive chemical weeding of cereal crops. Floristic differentiation of associations is confirmed by the results of the ordination analysis (Fig. 2), the diagram of which shows the distribution of communities along the moisture (first axis) and the complex soil richness–salinity gradient and agrocoenotic factor (second axis).
