Abstract Using vegetation as a bioindicator in urban and degraded areas is an effective way to assess the status of the environment. In this work, we present the results of a phytosociological investigation of a suburban river and of its surroundings in southern Tuscany (Bestina river and its tributary Bestinino in Asciano, Province of Siena). By means of 94 phytosociological relevés, we identified 34 plant communities belonging to the 17 classes. Six habitats included in the 92/43/EEC Directive, plus two habitats recently proposed for inclusion, were identified, as well as one habitat of regional interest. The study revealed that, despite the high levels of human disturbance, aquatic and herbaceous riparian vegetation is still well-preserved, though mostly represented by stress-tolerant communities. On the contrary, most of the vegetation types not being directly linked to the river dynamic are in poor conservation status. Despite this, some habitats of community interest were detected even in non-riverine sites. Our work provides the basic knowledge for future restoration of the Bestina river and of its surroundings, wished by the Tuscany Region.

Abstract Communities with constant presence of two insular endemic species of genus Brassica (B. cazzae Ginzb. et Teyber, B. mollis Vis.) were studied on the small southeastern Adriatic islands and islets (South Croatia), following the Braun-Blanquet approach. From a total of 51 phytosociological relevés, mostly collected in the period from 2020 and 2022, eight associations and three subassociations belonging to seven alliances and six classes were identified. Brassica cazzae and B. mollis occur in a variety of habitat types (i) in bare or very shallow soils on which halophilous and halotolerant communities of the Limonion anfracti-cancellati and Anthyllidion barbae-jovis mostly thrive, (ii) on rocky crevices and cliffs with rupicolous chasmophytic vegetation of the Centaureo cuspidatae-Portenschlagiellion ramosissimae, (iii) within woody vegetation of the Pistacio lentisci-Pinion halepensis, maquis of the Oleo-Ceratonion siliquae and garrigues of the Cisto cretici-Ericion manipuliflorae, and (iv) grasslands of the Chrysopogono grylli-Koelerion splendentis. Two associations (Plantagino holostei-Limonietum cazzae, Brassico mollis-Anthyllidetum barbae-jovis) and one subassociation (Centaureetum ragusinae limonietosum cazzae) are described for the first time.

Abstract Identification and characterization of forest habitats on the territory of the “Central Balkan” National Park in Bulgaria was carried out. The national park is one of the most valuable and largest protected areas in Europe – second category according to the International Union for Conservation of Nature (IUCN). Based on 786 phytosociological relevés, a total of 17 different habitat types, according to EUNIS were identified and mapped. The habitats were ecologically characterized by Ellenberg indicator values and their area was determined. A comparison was made with the areas determined in previous works. The applied method is suitable for the purposes of managing protected territories and zones, for monitoring the status and especially the conservation status of the habitats. The results and especially the established new habitats support this point of view.

Abstract The characteristics of shaded chasmophytic habitats on calcareous rocks in forest conditions are described, where the forest canopy primarily acts as a shading factor that determines microclimate, humidity and light levels. These communities can be found in deciduous forests of the Carpinion betuli, Fagion sylvaticae and Tilio-Acerion alliances, where they are confined to steep calcareous rock faces and cliffs. Syntaxonomically, these communities belong to the Polypodietea class (Ctenidio-Polypodietalia vulgaris order, Ctenidio-Polypodion vulgaris alliance) and to four informal communities: Isothecium alopecuroides-Polystichum braunii, Porella platyphylla-Asplenium ruta-muraria, Pseudanomodon attenuatus-Chrysosplenium alternifolium and Pedinophyllum interruptum-Polystichum aculeatum. We evaluated indices of environmental parameters according to the synphytoindication method using Didukh’s scales. An assessment of the threat impacts and indicators of sociological significance shows that the habitat belongs to a rare type (II class), and therefore requires specific conservation measures.

Abstract The plant communities dominated by Asphodelus ramosus are quite common in the Mediterranean Basin, especially in the most degraded vegetation stages caused by grazing and fires. The aim of this paper is to provide a phytosociological description of the Asphodelus ramosus-dominated plant community of the Murge Plateau, in southeastern Italy, through 28 phytosociological relevés. Cluster analysis (flexible Beta method) and ordination (non-metric multidimentional scaling) were used to compare this plant community with other dry grassland associations in the same area and with other Asphodelus ramosus-dominated plant communities from Italy and western Balkans. The results allowed the description of a new association for the Murge Plateau: the Gelasio columnae-Asphodeletum ramosi. The new association has been tentatively classified in the alliance Hippocrepido glaucae-Stipion austroitalicae (Scorzoneretalia villosae order), because of the presence of several species typical of this alliance, although it is intermediate between this alliance and the more thermophilous vegetation of the Lygeo sparti-Stipetea tenacissimae class.

Abstract Epipactis palustris (L.) Crantz is a protected species in Ukraine. In order to organize optimal protection measures comprehensive studies of various aspects of its biology are necessary. The aim of this study was to determine the pollinators and visitors of E. palustris. The study was conducted in Kyiv city (Ukraine) between 2020 and 2022. The research focused on arthropod visitors in two human-made populations. Specimens of 31 families and 48 genera from 9 arthropod orders were identified and established. The greatest number of species represented Hymenoptera, Coleoptera and Diptera. Evaluation of visitor activity show that Hymenoptera were the most frequent visitors. E. palustris in the conditions of Kyiv is mainly characterized by entomophily. Halictidae, Apidae and Coccinellidae played an important role in E. palustris pollination. It was found that populations of E. palustris in the conditions of the Kyiv city form a unique self-regulating biocenosis that provides shelter and food for 53 identified species of arthropods.

Abstract During field surveys, carried out between 2021 and 2022 in northeastern Algeria, two populations of Tipuana tipu (Benth.) Kuntze were discovered. One population was located in the middle of a quite natural habitat in the Filfilla region (wilaya of Skikda). This population seems more or less established and can be considered to be at the beginning of the naturalization process, a degree of naturalization not previously reported in Algeria and mainland North Africa. The surveys also revealed several populations of Paraserianthes lophantha (Vent.) I.C. Nielsen, a species that was recently reported as naturalized in Algeria but for which details on its naturalization were lacking. Details about the localities in which the two species were observed are given, including a present map of their distribution and field photographs. A key for the identification of both genera is also provided.

Abstract The vegetation developing on the coastal sand dunes and wetland of Schinias National Park, a Natura 2000 Site, was studied following the Braun-Blanquet method. Vegetation units were delimited using cluster analysis and by applying the fidelity measure; the phi-coefficient was used for the definition of diagnostic species. The vegetation types distinguished (twenty associations, two sub-associations and thirteen communities not assigned formal rank), which belong to 18 alliances, 16 orders and 12 classes, are discussed and presented in phytosociological tables. Among them Mathiolo tricuspidatae-Anthemidetum tomentosae, Pistacio lentisci-Pinetum halepensis pinetosum pineae, Puccinellio festuciformis-Aeluropetum litoralis cressetosum creticae and Tamaricetum tetrandrae are described for the first time. The vegetation types recognized in the study area are linked to twelve EUNIS habitat types, nine of which are related to 13 Annex I habitat types (Directive 92/43/EEC), and one to a habitat type of national interest (72A0). One Annex I habitat type occurring in the study area has scattered presence in the Natura 2000 network in Greece (1420), two are infrequent (2190, 2260), two are rare (2230, 2270) and three are priority habitat types (1150, 2250, 2270).

Abstract The Euphorbia resinifera is melliferous and medicinal plant and one of the endemic species of Moroccan Atlas Mountains. It is very well known for its honey of high nutritional and therapeutic quality. The objective of our study is to characterize and evaluate the phenotypic variation of this spontaneous species. Seventeen qualitative and quantitative morphological characters related to the bush, stem, spine, flower, and fruit of the plant were used to assess the morphological variability of twelve natural populations collected from its geographical range in Morocco. The results of the analysis of variance showed significant differences between the studied populations for the most examined traits reflecting the existence of a high phenotypic variability within this species. The principal component analysis showed that E. resinifera populations were clustered in three distinct groups not related to mountain range type. The results highlight a high phenotypic diversity within studied populations of this species in Morocco. This work aims to study the phenotypic variability of E. resinifera to delineate conservation strategies and also to establish forms of rational economic exploitation.

Abstract A research was conducted in the Veneto region (NE-Italy) inside kitchen gardens and potato fields of outer pre-Alps, and in asparagus fields on the low Po plain near the Adriatic coast, in late summer-autumn after harvesting. Original vegetation-plot records were compared with historic and recent materials from Italy, especially N-Italy, and with comparable associations from Central and South-Eastern Europe, to ensure a consistent syntaxonomical frame of this highly dynamic vegetation. At the same time it was possible to shed light on the actual occurrence of past coenoses, cited by Italian authors for the Po plain. The analysis not only confirmed the occurrence of Echinochloo-Setarietum pumilae in north-eastern Italian territories, but also showed that it was more extensive than previously thought. It also confirmed the persistence of Panico-Polygonetum persicariae. The historical presence of Veronico-Lamietum hybridi occurring in pre-Alps and Dolomites needs confirmation. Further regional-scale investigations of summer crop weed vegetation appear necessary.
