1999

Se aportan datos sobre el estado de conservación de cuatro plantas raras de la flora de la Comunidad Valenciana: Allium subvillosum, Himantoglossum hircinum, Orchis purpurea y Serapias parviflora. Se comenta el estado actual de sus poblaciones conocidas y se les atribuiryen las correspondientes categorías de la U.I.C.N. Data on the conservation status of four rare plants of the Valencian flora (Allium subvillosum, Himantoglossum hircinum, Orchis purpurea and Serapias parviflora) are reported. The current situation of their known populations is commented, and they are also labelled according to the current I.U.C.N. categories.

2017

Heterotheca subaxillaris (Compositae), a new xenophyte for the iberian flora. A first reference on the presence of Heterotheca subaxillaris (Lam.) Britton & Rusby (Compositae), native of North America, in the iberian flora is provided. This species has been located at the CV-10 highway, in la Pobla Tornesa, Castellón province (Spain).

Anthosart Green Tool: Selecting Species for Green Infrastructure Design

2021

The environmental and economic costs of greenery depend on the planning criteria adopted and on the plants used. These costs can become more sustainable and can also be significantly lowered by using native flora and getting inspired by local plant communities. Nature-based solutions entail the use of species that co-occur naturally, thus replicating a model of coexistence consolidated by the evolutionary coherence of the biosphere. Planning, using and (re-)producing – getting inspired by natural ecosystems – may foster the dissemination of ecological awareness, with gardens, avenues, rooftops, walls and balconies seen as spaces available for the urban reconciliation with nature. The Anthos…

Su alcune piante nuove delle Isole Pelagie

2013

On some new plants to Pelagic islands (Straits of Sicily) – Fifteen vascular plants belonging to the families Aizoaceae, Amaryllidaceae, Asteraceae, Brassicaceae, Euphorbiaceae, Myoporaceae, Orobanchaceae, Oxalidaceae, Portulacaceae and Solanaceae are reported as new to one or both the major Pelagic islands. With the exception of Narcissus serotinus and Orobanche minor, they are non-native plants, probably of recent human introduction, mostly in areas heavily modified by man. Myoporum insulare, widely used for reforestation and for ornament, occurs also in sub and semi-natural environments.

Addenda et emendanda to the "A catalogue of plants growing in Sicily"

2009

Corrections and integrations to the “A Catalogue of the plants growing in Sicily” by Giardina & al. (2007) are here reported. In particular, several disregarded taxa have been added and updated together with new other ones described or reported simultaneously or subsequently to the date of publication of the Catalogue. Finally nomenclature of some taxa has been updated and a new taxonomic status has been proposed for two of them.

Alien plant invasions in Mediterranean habitats: an assessment for Sicily

2021

AbstractLevels of plant invasions in different habitat types were assessed in several regional studies, but few of them were from the Mediterranean. Here we compare the levels of vascular plant invasion across habitats and plant communities of Sicily. We used a large dataset of plant species presences/absences in vegetation plots to analyze the invasion patterns across habitats considering biogeography, life form and phenology of alien plants. Vegetation plots were classified based on the EUNIS classification of European habitats. The invasiveness of each species was expressed in terms of its absolute and percentage frequency. Representation of different life forms and phenological patterns…

Invasive vascular plant species of oxbow lakes in south-western Poland

2015

Abstract Natural water reservoirs are very valuable floristic sites in south-western Poland. Among them, the most important for the preservation of biodiversity of flora are oxbow lakes. The long-term process of human pressure on habitats of this type caused disturbances of their biological balance. Changes in the water regime, industrial development and chemisation of agriculture, especially in the period of the last two hundred years, led to systematic disappearances of localities of many plant species connected with rare habitats and also to the appearance of numerous invasive plant species. They are: Azolla filiculoides, Echinocystis lobata, Erechtites hieraciifolia, Impatiens glandulif…
