“…The competitive nature of the plant did not explain the mechanism of its perpetuation and suppression of other plants. This plant was later identified as Euphorbia hypericifolia L, a Euphorbiaceae of the order Mapighiales [33]. Voucher specimens were deposited at the Limbe Botanic Garden Herberium (SCA: 1689).…”

Euphorbia hypericifolia, a non-native herbaceous weedy plant was found to often form disproportionately dense, virtually monospecific stands in the Mount Bambouto Caldera, Cameroon. This observation is within the purview of allelopathy and is attributed to the release of botanicals by non native plants that harm naïve native flora, creating significant problems for agriculture and the environment. We investigated if the invasiveness of E. hypericifolia could be explained by its allelopathic potential at varying concentrations on five indicator plants. The results showed that the leaf, root and stem aqueous extracts of the plant exhibited significant inhibitory effects on the germination, radicle and plumule lengths of Biden pilosa, Amaranthus spinosus, Lactuca sativa, Zea mays and Lycopersicon esculentum at 100 % by 75.0, 69.4, 95.6, 28.0 and 97.2 %, respectively. The leaf extract was the most potent, while the stem extract was the least. The extract of E. hypericifolia was stimulatory (Lower concentrations) and inhibitory to the germination and growth of the test plants and its effect was concentration-dependent with the roots of target plants being more sensitive to the extracts than the plumule. L. esculentum was the most susceptible species to E. hypericifolia extracts while Z. mays was more tolerant than any of the tested plants. Results of total chlorophyll pigment accretion showed declining levels of chlorophyll detected in the leaves of tomato transplants cultivated in the augmented soils with rising dosage of the leaf residue of E. hypericifolia. B. pilosa planted on E. hypericifolia infested soil (EIS) showed very poor emergence recording only 7.5 % after 6 weeks as compared to 83.0 % in non E. hypericifolia infested soil (NIS). Qualitative phytochemical screening indicates E. hypericifolia is rich in secondary metabolites including alkaloids, glycosides, flavonoids, phenolics, tanins, Steriods and saponins. Acetone was the best extractant amongst the solvents used. This study has proven the allelopathic potential of E. hypericifolia and revealed some allelochemicals that may be exploited for the development of bioherbicides and plant growth promotion from natural products.

“…Probably the disappearance of these species is linked to the spread of some invasive alien species (Ailanthus altissima, Opuntia ficus-indica, Arundo donax) that in some cases cover large areas (Figure 10), replacing the natural habitats and characteristic species. The invasion of alien species in Isole Ciclopi is a further confirmation of a widespread phenomenon in the coastal areas of Sicily (Sciandrello & al., , 2014(Sciandrello & al., , 2016 and surrounding islets (Minissale & al., 2005;Pretto & al., 2012;Minissale & Sciandrello 2017). Another important cause of the disappearance of some plant species or natural habitat is the excessive spread of Yellow-legged Gulls (Larus michahellis) in the spring and summer colonize the entire island for nesting, thus affecting the delicate ecological balance between plants, animals and soil, for the supply, with their droppings, of significant quantities of nitrates as already noted by Gristina & Marcenò (2008) for a coastal area of north-west Sicily.…”

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. Los datos recogidos se han organizado en un SIG y se han elaborado los siguientes mapas temáticos: mapa de vegetación, mapa de hábitats (Directiva 92/43/CEE)...
