This part of a series of paper presents a comparative characterization of selected stubble-field plant communities described in parts I-III. It encompasses the most important characteristic of the communities as well as the habitas in which they occur. In the differentiated climatically, geomorphologically, hydrologically and, most of all, in respect to soil type conditions of mideastern Poland, more precisely in the old limits of the Lublin voivodship, 6 types of stubble-field plant communities have been described and further classified into subunits; all of which have been isolated on the basis of the floristic composition of 330 analysed phytosociologocal records. The selected stubble-field plant communities were assigned to the suborder <i>Polygono-Chenopodietalia</i>. Among them, 3 plant associations known from root crop fields were identified: 2 belonging to the alliance <i>Panico-Setarion</i> (<i>Digitarietum ischaemi</i> and <i>Echinochloo-Setarietum</i>) and 1 belonging to <i>Eu-Polygono-Chenopodion</i> (<i>Oxalido-Chenopodietum polyspermi</i>). On most of the grain stubble-field of the Lublin region (almost 77% of the records) communities were found which could be assigned only to the alliances: community <i>Setaria glauca-Scleranthus annuus</i> to <i>Panico-Setarion</i>, community <i>Veronica persica-Sonchus asper</i> to </i>Eu-Polygono-Chenopodion</i> and community <i>Rorippa sylvestris-Oxalis stricta</i> which is an intermediate from between these alliances. The floristic types identified here, as well as their lower rancs (subassocietions variants, subvariants) were a reflection of the mechanical composition, nutritional, hydrological and pH conditions of the soils in their habitas and confirmed the high differentiation of soil conditions over the studied area.

In this of the presented paper results of the studies conducted in preceding four parts (I-IV) were synthetically assumed. On that background a comparative characteristics of specified stuble-field plant communities was conducted. It contains the most important features of communities and seats, in which they appear. In climatically, geomorphologically, hydrologically and with respect to soils differentiated conditions of South-East Poland, especially in former Rzeszów region, there were described stubble-field plant communities occurring as well on lowland, as on highland agricultural utility complexes. There were analysed 359 phytosociological records, in which 232 ones came from lowland, while 127 from highland complexes. The specified communities were included to two orders: <i>Secali-Violetalia arvensis</i> (suborder <i>Polygono-Chenopodienalia</i> : alliances <i>Eu-Polygono-Chenopodion</i> and <i>Panico-Setarion</i>) and <i>Cyperetalia fusci</i> (alliance <i>Nanocyperion flavescentis</i>). On the lowland agricultural utility complexes specified were seven types of communities: 3 belonged to <i>Panico-Setarion</i> alliance (association <i>Digitarietum ischaemi</i>; community with <i>Setaria glauca</i> and association <i>Echinochloo-Setarietum</i>), 2 to <i>Eu-Polygono-Chenopodion</i> alliance (the community with <i>Euphorbia esula</i> and <i>Oxalis stricta</i> as well the community with <i>Veronica persica</i>), while 2 associations from the <i>Nanocyperion flavescentis</i> (<i>Hyperico-Spergularietum</i> and <i>Centunculo-Anthocerotetum</i>) alliance. On the other hand, on the highland complexes of South-East Poland only 3 communities were found: 1) with <i>Setaria glauca</i> included to <i>Panico-Setarion</i> alliance, 2) with <i>Veronica persica</i> from <i>Eu-Polygono-Chenopodion</i> alliance and 3) <i>Centunculo-Anthocerotetum</i> association from <i>Nanocyperion flavescentis</i> alliance. The specified floral types, as well as lower units (variants and sub variants), reflected the mechanical structure, hydrological conditions and pH soils in their seats, what confrumed a great differentiation of soil conditions on the tested area.

Two plant communities have been distinguished on the fertile and humid solis in the Lublin region. I. <i>Oxalido-Chenopodietum polyspermi</i> Siss. 1942 (especially on the alluvial soils developed from loams, clays and silts); 2. <i>Rorippa sylvestris-Oxalis stricta</i> (on the loess, silts of water origin and alluvial soils developed from loamy sands). Each of the two types of communities was divided into two variants differing in floristic composition, which reflected the diversity of trophical, hydrological and pH conditions these soils.

Floristic diversity is characteristic for stubble-field plant communities. Those communities consist of both the species remaining after harvesting of grain and of the species developing in rootplant communities. The first part of this paper describes the plant communities of poor sites in the investigated region. It is based on 90 phytosociological records taken in August and September of 1972-1975 and on soil investigations. The <i>Panico-Setarion</i> alliance was made up of: 1) the <i>Digitarietum ischaemi</i> association, 2) the <i>Setaria glauca</i> community and 3) the <i>Ecbinochloo-Setarietum</i> association, the <i>Setaria glauca</i> community was divided into smaller phytosociological units.

In the Part I and II the stubble-field plant communities of lowlands agricultural utility complexes in South-Eastern Poland were introduced. The Part III contains a description of such communities occurring in mountain complexes. In the years 1972-1975, since August till September, 95 phytosociological records were taken on the area elevated from 300 to 650 m over the sea level, embracing the Carpathian Foreland and the Low Carpathian region. The research was conducted upon the typical, acid and leached brown soils, as well as on clay, dusty clay and silt alluvial soils belonging to three mountain complexes: wheat, cereal and oat-potatoes. The following communities were specified: I. <i>Setaria glauca</i> community, divided into two variants: 1) typical; 2) with <i>Aphanes arvensis</i>; II. <i>Veronica persica</i> community, divided into four variants: 1) with <i>Aphanes arvensis</i>, 2) typical, 3) with <i>Geranium dissectum</i>, 4) with <i>Aethusa cynapium</i>. The variant with <i>Geranium dissectum</i>, belonging to the community with <i>Veronica persica</i>, was considered as having the most mountain character.

Abstract One of the crucial debates in vegetation ecology is whether plant communities are discontinuous, distinguishable units or whether they change continuously. Phytosociology assumes discontinuity and its methodology requires subjective sampling during vegetation inventories. For that reason, some researchers argue that phytosociology artificially creates discontinuity among plant communities. Our aim was to assess the continuity between ash-alder riparian forest (Fraxino-Alnetum), and alder swamp forest (Carici elongatae-Alnetum), and to check whether discontinuity observed between these two plant associations is an effect of subjective sample plot choice. We conducted 57 phytosociological relevés within a regular grid covering potential sites of both plant communities. All relevés were arranged in order of decreasing relative cover of the diagnostic species for each plant association resulting in a gentle gradient, indicating a continuous transition from Fraxino-Alnetum to Carici elongatae-Alnetum. Similar results were obtained by detrended correspondence analysis. The proportion of species from the Querco-Fagetea class, typical to Fraxino-Alnetum, was decreasing with increasing proportion of species from the Alnetea glutinosae class, typical to Carici elongatae-Alnetum. This shift followed a gradient of ecological light-moisture indicator values. Our results confirmed continuous transition between two plant communities and led us to the conclusion that discontinuity resulted from the standard sampling protocol used in classical phytosociology. This protocol, however, is useful in searching for typological patterns, required for classification of plant communities, which is the main aim of phytosociology. Nevertheless, it does not provide full insight into the variability of vegetation and introduces uncertainty when trying to understand ecosystem dynamics. This uncertainty should be taken into account when phytosociological data are used for nature conservation recommendations and to draw conclusion about vegetation dynamics.

Natural water reservoirs are very valuable floristic sites, with springs particularly important for the preservation of floral biodiversity. This paper presents, as a case study, a community of water plants that is new to limnocrene karst springs in Europe: Potametum alpini (Potametea), found in Poland. The paper provides the floristic composition and ecological requirements of this plant association, which is rare and endangered in Europe. According to our knowledge, the habitat data presented here are unique as they are published for the first time for this plant community, and thus it is currently not possible to compare them with data from other authors. Our study confirms the importance of rare microhabitats for global biodiversity. Research on as yet unknown physical and chemical factors limiting the range and development of patches of different plant associations should be conducted intensively, because plant communities, including rare, endangered and protected examples, are an important element of biodiversity at both continental and local scales. All the issues discussed in the paper (rare microhabitats, endangered aquatic plant communities, global biodiversity) are important because they are related to the conservation and management of inland waters.

Abstract In the present study, we investigated plant communities with Yellow Oat Grass (Trisetum flavescens (L.) Pb.) in the submontane and montane regions of Slovenia. In 2005-2007 ninety-one relevés were collected by using the standard procedure of the Braun-Blanquet approach. Relevés were analysed with multivariate analysis and classified within two associations: Astrantio-Trisetetum (Polygono-Trisetion) and the Pastinaco-Arrhenatheretum (Arrhenatherion). Management practices, soil conditions and altitude were found to be significant factors for a further subdivision of both associations. Within the Astrantio-Trisetetum association three subassociations could be distinguished: -typicum, -buphthalmetosum and -trollietosum, and subassociations -typicum, -medicagetosumlupulinae, as well as -lolietosum subass. nova in the Pastinaco-Arrhenatheretum. The floristic composition and ecological characteristics of these plant communities are described and their implications for grassland conservation in Slovenia are discussed.

Phytosociology is a reference method to classify vegetation that relies on field data. Its classification in hierarchical vegetation units, from plant associations to class level, hierarchically reflects the floristic similarity between different sites on different spatial scales. The development of remotely sensed multispectral platforms as satellites enormously contributes to the detection and mapping of vegetation on all scales. However, the integration between phytosociology and remotely sensed data is rather difficult and little practiced despite being a goal for the modern science of vegetation. In this study, we demonstrate how normalized difference vegetation index (NDVI) time series with functional principal component analysis (FPCA) could support the analyses of phytosociologists. The approach supports the recognition and characterization of forest plant communities identified on the ground by the phytosociological approach by using NDVI time series that encode phenological behaviors. The methodology was evaluated in two study areas of central Italy, and it could characterize and discriminate six different forest plant associations that have similar dominant tree species but distinct specific composition: three dominated by black hornbeam (Ostrya carpinifolia) and three dominated by holm oak (Quercus ilex). The methodology was also able to optimize the ground data collection of unexplored areas (from a phytosociological point of view) by using a phenoclustering approach. The obtained results confirmed that by using remote sensing, it is possible to separate and distinguish plant communities in an objective/instrumental way, thus overcoming the subjectivity intrinsic to the phytosociological method. In particular, FPCA functional components (NDVI seasonalities) were significantly correlated with vegetation abundance data variation (Mantel r = 0.76, p < 0.001).

Plant communities with reed domination (Phragmites australis agg.) occupy the large areas in the Lower Volga Valley and especially in the river delta. We have set the task to reveal the diversity of these communities in the Lower Volga Valley. For this purpose, we applied the database that is registered in the Global Index of Vegetation-Plot Databases (GIVD) under the EU-RU–002 index (http://www.givd.info/) and includes 14871 relevés made during the period from 1924 to 2013. Communities with the dominance of reed were defined as such, if the coverage of this plant was more than 50 %. We have found 375 such relevés in the database. At first, one basal community, 3 associations and 3 subassociations with domination of Phragmites australis agg. were distinguished in the Lower Volga Valley. All processing and analysis of relevés were performed using the software package JUICE 7.0. (Tichý, 2002). The «Cocktail» method was applied to establish the sociological groups that indicate environmental conditions (Bruelheide, 2000). The expert system for selection from the database of relevés by means of these groups was created. It is allowed us to ascribe relevés to earlier distinguished associations, subassociations and basal community. 171 relevés have been identified by the expert system and they were assigned to association, subassociation or the basal community. 204 relevés were not referred to any association, subassociation or the basal community. We wanted to answer the question: are there among these 204 relevés, which could be interpreted as the new syntaxa, giving them the proper ecological characteristics? For this purpose, the cluster analysis of 204 relevés has been carried out. The optimal level of clustering was determined by calculating the index of “crispness of classification” (Botta-Dukát et al., 2005). The greatest “crispness of classification” was reached at allocation of 13 clusters. Consideration of the floristic composition of allocated groups had shown that 11 of them were the transitional plant communities among the earlier established syntaxa. Only two clusters were differed in rather original structure that we could explain by the influence of environment factors. We have identified them as new associations Rubio tataricae-Phragmitetum australis and Cynancho acuti-Phragmitetum australis. All associations with the dominance of Phragmites australis agg. distinguished in the Lower Volga Valley were included in the alliance Phragmition communis Koch 1926, order Phragmitetalia communis Koch 1926. In literary sources from the ecological point of view these syntaxa are defined as the wetland communities, which are closely linked to water bodies (Šumberová et al., 2011; Ermakov, 2012). However, in many cases this definition does not correspond to the ecology of plant communities with the dominance of reed in the lower reaches of the Volga River. Ecotops of these communities are flooded for up to 2–3 months in a year and then they dry out. In the autumn, the ground water level can drop to a depth of one meter (Golub et al., 2011). The plant satellites of the reed here are often mesophytic plants such as Rubus caesius, Calamagrostis epigeios, Phalaris arundinacea, Rubia tatarica, Althaea officinalis, and Rumex stenophyllus. Therefore, the inclusion of phytocoenosises with domination of the reed in the lower reaches of the Volga River in the alliance Phragmition communis is rather relative. A correct placement of these plant communities in the system of vegetation syntaxa of the arid areas can be made only if it is based on original data obtained from much bigger territory than the Lower Volga Valley. In future geobotanical studies, it is desirable to divide the aggregation of Phragmites australis agg. into smaller species taxa.
