Syntaxonomical Remarks on the Garrigues from Apulia (S Italy) and Neighboring Territories.

In this study, the garrigues occurring in Apulia and neighboring territories (southern Italy) were surveyed in order to clarify their syntaxonomical arrangement. Many contributions previously focused on this vegetation type, often adopting different and sometimes contrasting treatments from both the nomenclature and syntaxonomical aspects. Our investigations are supported by the multivariate analysis of a dataset containing 292 phytosociological relevés, whose resulting cluster dendrogram highlights the hierarchical relationships between the examined plant communities.

Taxonomic and ecological remarks on species complex (Campanulaceae).

New Data on Native and Alien Vascular Flora of Sicily (Italy): New Findings and Updates.

In this paper, based on fieldwork and herbaria surveys, new data concerning the presence of 32 native and alien vascular species for Sicily (Italy) are provided. Among the native species, the occurrence of the following is reported for the first time or confirmed after many decades of non-observation: , , subsp. , , , and .

Ecological Features and Conservation of Guss. (Urticaceae): A Narrow Endemic Species of Sicily.

The conservation actions of endangered plant species require a clear knowledge of their habitats. Guss. (Urticaceae) is a rare endemic plant species occurring on shady cliffs in the southern-eastern part of Sicily.

The Plant Communities of the Class in Sicily.

A syntaxonomical revision of the class for the Sicilian territory is provided. This syntaxon gathers the ephemeral herbaceous hygrophilous plant communities linked to periodically submerged soils, widely distributed in the European, circum-Mediterranean and Macaronesian territories. Within this class, two orders are recognized, , with a prevalently Mediterranean distribution, and chiefly occurring in the central-European and Atlantic territories, with scattered and marginal occurrence in the Mediterranean area.

Unexpected Discovery of () in Sicily (Italy): Morphological, Ecological Analysis and Habitat Characterization.

Schott (), known as "marsh fern", is infrequent in the Mediterranean area. The occurrence of this species is known for almost all the Italian regions (except for Sardinia and Sicily), but with rare and declining populations. During floristic fieldwork on the Sicilian wetlands, a new unknown population was found.

Past, present, and future geographic range of the relict Mediterranean and Macaronesian complex.

Aim: The aim of this study is to model the past, current, and future distribution of ., , and , based on bioclimatic variables using a maximum entropy model (Maxent) in the Mediterranean and Macaronesian regions.

Location: Mediterranean and Macaronesian.

Floristic and Vegetation Changes on a Small Mediterranean Island over the Last Century.

A synthetic and updated overview about the vascular flora and vegetation of the Island of Capo Passero (SE-Sicily) is provided. These data issue from two series of field surveys-the first carried out between 1997 and 2000, and the second between 2005 and 2019 and mostly focused on refining and implementing vegetation data. The current islet's flora consists of 269 , of which 149 (58%) are annual plants.

Vascular plant species diversity of Mt. Etna (Sicily): endemicity, insularity and spatial patterns along the altitudinal gradient of the highest active volcano in Europe.

Background: Altitudinal variation in vascular plant richness and endemism is crucial for the conservation of biodiversity. Territories featured by a high species richness may have a low number of endemic species, but not necessarily in a coherent pattern. The main aim of our research is to perform an in-depth survey on the distribution patterns of vascular plant species richness and endemism along the elevation gradient of Mt.

Impact of invasive alien plants on native plant communities and Natura 2000 habitats: State of the art, gap analysis and perspectives in Italy.

Invasive alien plants are a major threat to biodiversity and they contribute to the unfavourable conservation status of habitats of interest to the European Community. In order to favour implementation of European Union Regulation no. 1143/2014 on invasive alien species, the Italian Society of Vegetation Science carried out a large survey led by a task force of 49 contributors with expertise in vegetation across all the Italian administrative regions.
