Aims: To link the Braun-Blanquet units of the EuroVegChecklist (EVC) with the upper levels of the International Vegetation Classification (IVC), and to propose a division level classification for Europe. Study area: Europe. Methods: We established a tabular linkage between EVC classes and IVC formations and identified mismatches between these two levels. We then proposed IVC division level units to organize EVC classes. Results: We organized the EVC classes into 21 formations and 30 divisions. We flagged classes that did not fit comfortably within an existing formation, either because its content corresponded to more than one formation or because it did not fit any formation description. In a few cases, we split EVC classes because they seemed too heterogenous to be assigned to a single formation. Conclusions: The IVC approach adds a set of physiognomic and ecological criteria that effectively organizes the EVC classes, which are already being increasingly informed by physiognomy. Therefore, the formation concepts are relatively natural extensions of concepts already embedded in the classes. However, physiognomic placement of Braun-Blanquet classes can be difficult when the sampling of the vegetation is at finer grain than usual in the respective formation (tall-scrub, annual pioneer communities). Some EVC classes seem too heterogenous to fit into the IVC formation system. Delimitation of these classes has often been a matter of debate for many decades, and the IVC perspective might help to solve these intricate issues. In other cases, mismatches between phytosociological classes and IVC formations might better be solved by emending the current formation concepts.

The 2nd international scientific conference «Fundamental problems of vegetation classification» took place at the Nikitskiy Botanical Garden (Yalta, Republic of Crimea, Russia) on 15–20 September 2019. There were 56 participants from 33 cities and 43 research organizations in Russia. The conference was mostly focused on reviewing the success in classification of the vegetation done by Russian scientists in the past three years. The reports covered various topics such as classification, description of new syntaxonomical units, geobotanical mapping for different territories and types of vegetation, studies of space-time dynamics of plant communities. The final discussion on the last day covered problems yet to be solved: establishment of the Russian Prodromus and the National archive of vegetation, complications of higher education in the profile of geobotany, and the issue of the data leakage to foreign scientific journals. In conclusion, it was announced that the 3rd conference in Nikitskiy Botanical Garden will be held in 2022.

Mapping Data

Diversity of plant communities in the nature reserve “Privolzhskaya Forest-Steppe”, Ostrovtsovsky area, is analyzed on the basis of the large-scale vegetation mapping data from 2000. The plant community classi­fication based on the Russian ecologic-phytocoenotic approach is carried out. 12 plant formations and 21 associations are distinguished according to dominant species and a combination of ecologic-phytocoenotic groups of species. A list of vegetation classification units as well as the characteristics of theshrub and woody communities are given in this paper.

Formation System

This study aims at investigating the development of grammatical theory at the Institute of the Ukrainian Language for the last 30 years. The paper summarizes achievements in grammar theory from applying the functional, i.e., semantic and grammatical, approach developed by I.R. Vykhovanetsʹ to differentiating units into word and nonword classes and distinguishing morphological categories of major word classes. This facilitated the establishment of the theoretical basis of functional and categorical morphology. The author analyses studies in formal grammatical, semantic, functional, categorical, deri vational, and anthropocentric syntax that attest to the multidimensional growth of a syntactic theory and main aspects of the Ukrainian word formation on the basis of semantic and categorical syntax and a formant- and stem-based derivatology. Some of the latest multi-pronged processes in word formation reflect dynamics of word formation rules, the replenishment of word formation resources, and the development of the word-formation system of Standard Ukrainian. The solving of a complex set of theoretical issues in the modern Ukrainian word-formation introduced the methodological foundations for the recent normative description of the word formation system of Standard Ukrainian. The article addresses issues in studies on applied grammar determined by the process of glo balization and democratization of the Ukrainian society and the needs of Modern Ukrainian language practice to be met. Particular importance is attached to the grammatical prescriptive norms in the professional use, the actualization of case forms appearing in the passive vocabulary, and the dynamics of morphological and syntactic norms in various functional and stylistic dimensions of Standard Ukrainian. Keywords: functional grammar, functional morphology, functional syntax, categorical grammar, categorical syntax, categorical word formation, classification of parts of speech, morphological categories.

Sclerophyll Forests

The distribution and abundance of the carabid beetle fauna of selected grassy ecosystems, wet and dry sclerophyll forests, and wet heaths in the Eastern Tiers, Tasmania was examined using pitfall traps. The conservation values of the sites were assessed by applying evaluation criteria typically used for vegetation (i.e., representativeness, typicalness, diversity and rarity) to both the carabid fauna data and the vegetation data. Sites of high conservation value for carabids and vegetation were identified and compared. Sites that ranked highest in terms of the carabid fauna on all conservation criteria were not the sites that ranked highest based on the vegetation. Classification of sites produced different results depending on whether plant or carabid data were used. Conservation based solely on vegetation attributes will therefore not necessarily conserve a rich and/or representative carabid fauna. If the objective to conserve a representative range of all biota is to be met, the use of additional taxa such as carabids in conservation assessments is desirable.

This article is the second part of the series of publications on vegetation classification of communities with invasive species in the South Urals (Abramova, 2011). The communities with a presence of two aggressive species of North American origin such as Cyclachaena xanthiifolia (Nutt.) Fresen. and Xanthium albinum (Widd.) H. Scholz. are presented. Both species are included in “The black book of flora of the Central Russia” (Vinogradova et al., 2010). Research was conducted during 2000–2009 in the territory of Bashkortostan Republic. Species invasion in the region and their naturalization on flood plains of the South Urals was noted (Abramova, Anufriyev, 2008; Abramova, 2014; Abramova, Nurmiyeva, 2014). In the centers of invasion of mentioned species 110 complete geobotanical descriptions of communities on trial platforms of 4–100 m² were executed. Classification of communities with the invasive species is carried out according to the Braun-Blanquet method with application of the deductive method (Kopečky, Hejny, 1974). The allocated syntaxa were compared to units earlier described in Bashkortostan Republic and other regions (Vegetace …, 2009; Yamalov et al., 2012; etc.).

Natural Grassland

As part of a programme of landscape-scale habitat surveillance in the United Kingdom (UK), the effect of grassland sampling intensity on the outcome of numerical classification was assessed. Sample quadrats from two regions of the UK were available for post priori analysis; a random sample from Great Britain (GB), with grasslands sampled in proportion to area, and an independent stratified random sample from Northern Ireland (NI), with similar numbers of quadrats from agricultural and semi-natural grassland habitat strata. Classification of a combined area-proportional (balanced) random sample from GB and NI showed the species composition of UK grasslands to be determined largely by climate, landscape structure and land-use intensity. The classification was influenced primarily by the greater number of eutrophic agricultural grassland quadrats and semi-natural grassland quadrats of the larger GB study area. The semi-natural grasslands of NI, represented by a small number of quadrats, had little influence. Classification of a stratified NI sample combined with an area-proportional GB sample was influenced most by the NI semi-natural grassland quadrats. The structure of the classifications depended on sampling intensity. Vegetation classification should be derived from a balanced sample so that it is representative and its application does not lead to decisions being directed at classes of vegetation (or estimates derived from them) that are weighted by sampling intensity. Area-proportional sample design linked explicitly to landscape structure satisfies the requirement for a balanced classification. The issue of data-balance is relevant in conservation management and environmental assessment, where stratification is a commonly accepted procedure to reduce sampling effort, or is carried out to sample rare or ecologically interesting vegetation. It applies to landscape-scale vegetation classifications used for environmental assessments and to classifications that compare plant communities between regions (as in phytosociological studies). The issue is also important when combining environmental databases from international sources for classification purposes.
