“…Cypero-Limoselletum is widespread in Europe and Asia (e.g. Pietsch, 1973 ; Rašomavičius & Biveinis, 1996 ; de Foucault, 2013 ; Dubyna et al, 2015 ; Taran, 2019 ), it was also classified as a community Cyperus fuscus-Limosella aquatica ( Popiela, 1997 ). Cypero-Limoselletum is well separated vegetation units of cyperoids, rarely enriched (especially of exposed pond bottoms) by diagnostic species of Polygono-Eleocharitetum.…”

Formalized classification of the class Isoëto-Nanojuncetea has not been performed in Poland. We used 69,562 relevés stored in Polish Vegetation Database. Based on the literature and expert knowledge we selected 63 diagnostic species for the Isoëto-Nanojuncetea class. Unequivocal classification was applied in this work according to Cocktail method. A set of formal definitions was established using a combination of logical operators of total cover of species in case of high-rank syntaxa while sociological species groups and cover of particular species were used for logical formulas describing class, alliances and associations. An Expert System was prepared and applied to classify the whole data set of PVD and 1,340 relevés were organized at the class level. We stratifies the data and finally we used data set of 903 relevés to prepare synoptic tables, distribution maps and descriptions of the syntaxa. Twelve associations and two plant communities were identified. Vegetation of the Isoëto-Nanojuncetea class occur in Poland’s central and southern part, with scattered stands in northern region. We described two new plant communities within Eleocharition and Radiolion alliance. The first formal classification of the Isoëto-Nanojuncetea class revealed a high diversity of ephemeral vegetation wetland found in Poland in the eastern boundary of their geographical distribution in Europe.

“…In this aspect, it is possible to make parallels with the variability of ecological gradients for subalpine vegetation, which also develops in extreme ecotopes (Čarni et al, 2011;Dyakov, 2014). These features cause the extreme vulnerability of pioneer vegetation to biotic and abiotic changes , determine the weakness of its coenotic connections and low anthropotolerance (Dubyna et al, 2015(Dubyna et al, , 2016a, which requires immediate action for conservation of this specific and unique type of phytocenosis.…”

Pioneer plant communities grow on newly-formed ecotopes of coastal and partially continental areas, on patches that have dried after the surface water flooding. They are affected by sea tides, wind-induced effect, salinity, denudation, accumulation and sharp changes in soil humidity. To these factors are added chemical and biological pollution, as well as anthropogenic pressure. Due to these reasons, such plant communities have a specific floristic composition, structure, functional regime and resilience mechanisms, which are different from coenoses of more stable habitats. On the basis of the analysis of more than 600 phytosociological relevés using TWINSPAN modified algorithm the current state of littoral and halophytic classes of pioneer vegetation in Ukraine has been established and their syntaxonomic structure identified. It has been determined that the level of pioneer phytocoenoses diversity in Ukraine is similar to that of Central Europe. The Cakiletea maritimae class is presented by 1 order, 1 alliance, and 4 associations; Ammophiletea – by 1 order, 1 alliance, and 8 associations; Crithmo-Staticetea – by 1 order, 2 alliances, and 3 associations; Crypsietea aculeatae – by 1 order, 3 alliances, and 4 associations, Therosalicornietea – by 1 order, 2 alliances, and 10 associations. Synoptic tables of vegetation classes are given and nine alliances are briefly characterized. Using DCA-ordination analysis of syntaxa in the association-rank level we identified that the main factors of ecological differentiation are soil humidity and aeration as well as the nitrogen content. For the pioneer plant communities, other significant impact factors are the extremality of environmental conditions, their unevenness and non-equilibrium, in particular, the mechanical action of the sea waves, the dynamic processes of denudation and accumulation, salinity, as well as the variability of damping during the year. This research contributes to the identification of the place of the distinguished syntaxa of Ukrainian pioneer vegetation in the European system.

“…It is diagnostic of several European plant communities. Lacking of Western taxa, some of these (Cyperetum micheliani, Lindernio-Dichostylidetum michelianae) are clearly continental, known from Central and Eastern Europe (Trpin et al 1996;Jasprica et al 2003;Šumberová 2011;Dubina et al 2015). Except for Cyperus fuscus, the diagnostic species of Cyperetum micheliani sensu Šumberová (2013) are rare or completely missing along the Po river.…”

The ephemeral vegetation dominated by Cyperus sp. pl. was surveyed and analyzed along the eastern trait of the Po River (Po Plain, Italy). Two formerly described communities were recognized: Cyperetum esculenti and Amaranthus tuberculatus-phytocoenon. A third greater cluster is assigned to a new association: Cyperetum micheliano-glomerati. It is characterized by Cyperus glomeratus, C. michelianus, C. odoratus and C. squarrosus, that have been detected on over 75 % of the relevés. The main floristic and ecological traits of these detected vegetation types are discussed.
