“…desertorum and Tortula brevissima, also grow only here in Italy (Privitera et al, 2002). This fact is of major biogeographical significance as it is evidence of the floristic exchange between the Italian peninsula and North Africa through Sicily during the Pleistocene epoch (Bonfiglio et al, 2002;Pignatti, 2011;Sciandrello et al, 2015).…”

Habitat, occurrence and conservation status of the Saharo-Macaronesian and Southern-Mediterranean element Fagonia cretica L. (Zygophyllaceae) in Italy

Fagonia cretica L. is an important component of Mediterranean dry grasslands and a rare and isolated species of Italian flora. In this study, an assessment is presented on the distribution, habitat, and conservation status of F. cretica in Italy. The results of field investigation and herbarium analysis show that this species grows in a small area within the southern Calabria region characterized by a warmest and driest Mediterranean climate on the Italian peninsula. F. cretica is a semi-desert plant species growing in Italy in only one peripheral and isolated population at the northern limit of its distribution. Plant community analysis, using the phytosociological method, shows that F. cretica grows in wintergreen perennial dry grasslands dominated by Lygeum spartum and Hyparrhenia hirta. F. cretica plant communities are located in thermo-xeric habits such as south-, southeast-and east-facing slopes on clays and sandy clays in southern Calabria. The population of F. cretica is fragmented in six neighbouring localities, with two of which belonging to a Site of Community Importance (SCI). The conservation status of F. cretica population is not very good, and is defined as "Critically Endangered" in accordance with IUCN criteria. There are many threats affecting the F. cretica population in Italy, primarily the changes in land uses due to urban expansion and reforestation with exotic plants. The southern end of the Italian peninsula hosts other plants from thermo-xeric habits that do not adapt to the current local climate. This territory can be considered as a microrefugia for plants currently distributed in the arid territory of the southern Mediterranean. These results contribute to the discussion of some conservation measures, and the possibility of establishing a micro-reserve. For all these reasons, we propose to include F. cretica in the lists of protected plant species at regional (Calabria) and country (Italy) scales in Italy.

“…In other cases, the geology suggested possible solutions to explain the current genetic structure of some species (e.g. Ambrosinia bassii, see [40,41]), or was fundamental in the definition of the borders of phytogeographical units [42], but in this case, the importance of this part of Sicily "risks" being greater.…”

A new species of Brassica sect. Brassica is described here from Sicily (Italy), which is known to be one of the centers of the diversification of wild taxa of this group. The new species (named Brassica tardarae) is restricted to the carbonate cliffs in the Tardara Gorges between Menfi and Sambuca di Sicilia (Agrigento province), an area with a peculiar geological history and where another strictly endemic species was recently described. The morphological relationships between the new species and other similar taxa are discussed, and an analytical key to the Sicilian taxa belonging to the genus Brassica sect. Brassica is also provided.

This paper provides an update inventory of the vascular flora and a framework of the plant communities of the Isole dei Ciclopi (Acicastello, Catania) taking into account their geological setting. A total of 111 phytosociological relevés were performed in the period 2015-2016. The plant communities has been analyzed using WPGMA and Euclidean distance classification. The study area preserves interesting plant-communities, mainly represented by shrubs vegetation (Oleo-Ceratonion siliquae and Pruno-Rubion ulmifolii), rocky coast communities (Crithmo-Staticion), cliff vegetation (Anthyllidion barbae-jovis), halo-nitrophilous vegetation (Pegano-Salsoletea), spring-flowering meadows (Frankenion pulverulentae) and nitrophilous communities (Allion triquetri and Echio-Galactition tomentosae). The vegetation analysis allow the identification of twelve vegetation types and also the reconstruction of three vegetation series. The collected data have been organized in a GIS and the following thematic maps have been produced: vegetation map, habitats map (according to the 92/43/EEC Directive). According to directive 92/43/EU, only three habitat types were delimited through the phytosociological assessment of the plant communities. The flora of the investigated area consists of 102 taxa. The majority of the taxa represented in the life form spectrum are therophytes and hemicryptophytes. From a chorological point of view, the Mediterranean element outweighs the rest, followed by the most diverse group of widespread taxa. Furthermore a detailed geological investigation was carried out and a geological sketch map was performed. The comparison between the vegetation and geological maps shows a good correlation, mostly regarding the distribution of the plant communities onto the different types of substrata.[es] La vegetación y su relación con el sustrato geológico: el caso de Isole dei Ciclopi (este de Sicilia, Italia)Resumen. Se presenta un inventario actualizado de la flora vascular y de las comunidades vegetales de la Isole dei Ciclopi (Acicastello, Catania) teniendo en cuenta su situación geológica. Se realizaron un total de 111 inventarios fitosociológicos en el período 2015-2016. Las comunidades de plantas se han analizado mediante clasificaciones (WPGMA, distancia euclídea). El área de estudio conserva interesantes comunidades vegetales, representadas principalmente por vegetación arbórea (Oleo-Ceratonion siliquae y Pruno-Rubion ulmifolii), comunidades costeras rocosas (Crithmo-Staticion), vegetación de acantilados (Anthyllidion barbae-jovis), vegetación halo-nitrófila-(Pegano-Salsoletea), comunidades terofíticas de carácter halófilo (Frankenion pulverulentae) y comunidades nitrófilas (Allion triquetri y Echio-Galactition tomentosae). El análisis de la vegetación ha permitido la identificación de doce tipos de comunidades y la reconstrucción de tres series de vegetación.
