Phytosociological Study

Our phytosociological study in Montenegro (Ćemovsko polje) deals with the syntaxonomy of arid grasslands in the Adriatic region and, in particular, different interpretations of plant communities dominated by Asphodelus ramosus. The main aims of this study were to contribute to knowledge of the composition of dry grasslands dominated by Asphodelus ramosus in Montenegro and to compare instances of Asphodelus ramosus dominated vegetation along the Adriatic. Our vegetation dataset included 82 phytosociological relevés: 17 from our recent field work and 72 relevés of South European Asphodelus ramosus communities. Ordination analysis (NMDS) was used for comparison of Asphodelus ramosus dominated communities in the Adriatic region. The Asphodelus ramosus community from Montenegro was classified into Bromo erecti-Chrysopogonetum grylli. The analysis revealed two distinct vegetation groups: grassland communities of the vegetation class Festuco-Brometea from Montenegro, Croatia and Albania, and edge vegetation of the new class Charybdido pancratii-Asphodeletea ramosi from Italy. Comparison with similar vegetation types shows high similarity with associations on the eastern Adriatic coast, where they are treated as grassland communities belonging to the alliance Chrysopogono grylli-Koelerion splendentis, order Scorzoneretalia villosae, class Festuco-Brometea.

Phytosociological Study

Velika plaža (Ulcinj, Montenegro) is the largest sandy beach along the coast of the eastern Adriatic that still has well-developed sand-dune vegetation. Although the characterization of the flora and vegetation of Velika plaža has been addressed by many authors, knowledge on its vegetation remained poor. We made a phytosociological study of sand beach vegetation comprising both dunal and wetland areas to provide a comprehensive survey of sand dune vegetation and habitat typology of Velika plaža. Based on 149 relevés (both from literature and recent field work), and with numerical classification (Flexible beta) and ordination (Non-metric multidimensional scaling) our results show that the vegetation of Velika plaža is much more diverse than previously known. Altogether, 19 plant communities from 6 vegetation classes were identified. Among them we described two new associations: Cuscuto cesatianae-Phyletum nodiflorae and Onobrychido caput-galli-Vulpietum fasciculatae.

Phytosociological Relevés

The results of a phytosociological investigation regarding the orophilous cushion-like vegetation occurring in the top of the high mountains of central-southern Greece and in some Ionian (Lefkas, Cephalonia) and Aegean Islands (Euboea, Samos, Lesvos, Chios and Thassos) are provided. Based on 680 phytosociological relevès (460 unpublished and 220 from literature), a new syntaxonomical arrangement is proposed with the description of a new class, including two new orders, eight new alliances, and several associations (many of them new). Compared to the previous hierarchical framework usually followed in the literature, this study provides a more realistic and clear phytosociological characterization of this peculiar and archaic vegetation type, which is exclusive to the high mountains of the north-eastern Mediterranean. The new arrangement is mainly based on the phytogeographical role of the orophytes featuring this very specialized vegetation, which is essentially represented by endemics or rare species belonging to the ancient Mediterranean Tertiary flora. In addition, taxonomic research on the orophilous flora occurring in these plant communities allowed to identify six species new to science (i.e., Astragalus corinthiacus, Allium cremnophilum, A. cylleneum, A. orosamium, A. karvounis, and A. lefkadensis) and a new subspecies (i.e., Allium hirtovaginatum subsp. samium), and two new combinations (i.e., Astragalus rumelicus subsp. euboicus and subsp. taygeticus) are proposed.

Effect of Management Modification on the Coenological Composition of the North Adriatic Pastoral Landscape (Ćićarija, Croatia)The research aim was to assess the dynamics of the North Adriatic pastoral landscape (Ćićarija, Croatia) with regard to the coenological composition of grassland communities, and, more specifically, to: i) assess the current grassland mosaic from a coenological viewpoint; ii) assess the effects of management abandonment on grassland species composition, also taking into account, as a basis for comparison, data on pastoral communities collected in the past decades. To achieve the research aims, 73 phytosociological relevés were carried out; for each of them field data (altitude, aspect, slope, landform) and information on grassland management were collected. Multivariate analysis of phytosociological relevés led to the identification of four vegetation types (Danthonio-Scorzoneretum villosae, Carici humilis-Centaureetum rupestris, Brachypodium rupestre-dominated stands, andAnthoxantho-Brometum erecti), which were linked to landform and to grassland management. Comparison in terms of social behaviour type composition of the grassland communities surveyed in the present study with the ones surveyed in the past decades, highlighted that the current management (grassland abandonment, as well as low intensity grazing and not periodic mowing) is leading to a percentage loss of pasture and meadow characteristic species, in favour of successional and ruderal ones.

Abstract Numerical taxonomic study of the genus Crotalaria L. in Nigeria was conducted to identify and differentiate some of the species of the genus Crotalaria using numerical taxonomy based on quantitative and qualitative characters. Field work was conducted, where different species were collected and analyzed using multivariate analysis. The results showed that all the collected species are distinct at Euclidian distance of 0.41 in the cluster analysis with Cophenetic correlation (r)=0.964. The ordination analysis based on the results of the PCA, separated the specimens into 7 groups corresponding to the result of cluster analysis. The first two components of the PCA account for 81.5%. The length of petiole, width of leaflet and length of fruit contributed more to showing delimitation among the species.

Phytosociological Study

Abstract The present phytosociological study of the eastern Adriatic coastal salt-marsh at Blato, Croatia, is based on the Braun-Blanquet approach. Five plant associations were recorded in the area: Juncetum maritimo-acuti, Puccinellio festuciformis-Sarcocornietum fruticosae, Scirpetum maritimi, Enteromorpho intestinalidis-Ruppietum maritimae and Cressetum creticae. The association Cressetum creticae was found for the first time in Croatia as well as on the eastern Adriatic coast. This therophytic and halo-nitrophilous association shows a monospecific or paucispecific character and occupies the most haline and the driest parts of the salt-marsh. The association develops during the summer on silty clay substrates with organic matter derived from the decay of plants of the neighboring communities. According to key soil factor analysis no differences of grain size of the soils among the associations were found, while regarding electrical conductivity, Cl- and Na+ concentrations were higher in the Cressetum creticae than in any of the others associations. The particular original features of the site regarding its flora and vegetation would justify some measures of protection and management.

Phytosociological Study of Beech and Beech-Mixed Woods in Monti Sibillini National Park (Central Apennines, Italy)The results of a phytosociological survey of the woods mainly growing on limestones in the Southern part of the Marches Region (Central Italy), that is part of the Monti Sibillini National Park, are here presented. This area is characterized by a temperate climate (upper mesotemperate and lower/upper supratemperate bioclimatic belts). In order to study the vegetation, 173 phytosociological relevés were carried out through the Braun-Blanquet methodology. All the data obtained were submitted to multivariate analysis. The phytosociological analysis is characterized in nine associations, whereof three are of new description (Lathyro veneti-Fagetum sylvaticae hieracietosum murorum, Cardamino kitaibelii-Fagetum sylvaticae corallorhizetosum trifidaeandCardamino kitaibelii-Fagetum sylvaticae anemonetosum nemorosae).

Phytosociological Study

In the present paper a phytosociological study on the dry grassland communities identified in the western sector of the Murgia Plateau (Murgia delle Gravine) and in the Lucanian badlands territory is presented. Forty vegetation releves were carried out using the Braun-Blanquet phytosociological approach. Two new associations characterized by a therophytic dominance, namely Lysimachio foeminae-Atractylidetum cancellatae and Campanulo erini-Micromerietum microphyllae, are described and discussed from a syntaxonomic and biogeographic viewpoint. In addition, new phytosociological data concerning the Petrosedum ochroleucum communities developed on limestone outcrops, the perennial Hyparrhenia hirta steppe-like grasslands of the low-altitude areas of the Murgia hills and the small-size Brachypodium distachyum therophytic communities are presented.

Genista lydia Boiss. is an endemic Balkan-Anatolian species which forms rare communities in the territory of south Bulgaria and northeast Greece. They are spread exclusively on acidic, siliceous substrates. This study presents new data on their distribution, floristic and ecological structure and phytosociological affinities. The research is based on 156 phytosociological relevés. Unweighted pair–group method with arithmetic averages (UPGMA) was employed and a detrended correspondence analysis (DCA) was performed prior to the syntaxonomical decision. Three new associations and the new alliance Genistion lydiae have been described and classified within the order Lavandulo stoechadis-Hypericetalia olympici Mucina in Mucina et al. 2016 of the class Cisto-Lavanduletea stoechadis Br.-Bl. in Br.-Bl. et al. 1940. The study has also emphazised the potential threats concerning a decline of the habitat area and proposed some conservation measures.

This work is a phytosociological approach to the montane rainforests of Peru with the aim of advancing on the diversity of plant communities, which we had already begun in previous research. From 364 phytosociological plots and 3389 species of the South American tropics, we have developed a cluster, using the Sørensen index, to know the similarities between the forests and their parallelism with bioclimatic conditions. After studying the existence of characteristic groups of the Peruvian forests, we have established different communities and phytosociological units for Peru. As a result, we have described seven associations, within three new alliances, which are gathered in the new order Saurauio peruvianae-Condaminetalia corymbosae of the new class Morello pubescentis-Myrsinetea coriaceae. In addition, two associations have been described within the class Pruno rigidae-Oreopanacetea floribundae (mesotropical laurel-like forests), and three for the class Alnetea acuminatae (alder forests and palm groves). The humid forests of Peru are closer to those of Ecuador and to those of the set formed by the three Colombian mountain ranges than to those of Bolivia and Argentina, due to the common flora these share with areas of Paraguay and even of the Parana River region.
