A methodological protocol for Annex I Habitats monitoring: the contribution of Vegetation science.
2016
The methodological foundations of the recently published Manual for Annex I Habitats monitoring in Italy, edited by the Italian Institute for Environmental Protection and Research (ISPRA) with the scientific support of the Italian Society for Vegetation Science (SISV), are here presented, discussed and related to the most consolidated and acknowledged scientific advances in the field of Vegetation science. The proposed methodologies aim at offering simple, yet effective, protocols and procedures towards a harmonized data collection, by way of standardized and shared technical tools, resulting in comparable evaluations of the conservation status of Annex I Habitats. The methodological framew…
WILD RESOURCES OF THE PROSPECTIVE MEDICINAL PLANT ARUM MACULATUM L. IN BULGARIA
2015
Background: Arum maculatum L. (Araceae), has been known as a medicinal plant for centuries. In Bulgaria, this species is an officially acknowledged medicinal plant (Medicinal plant act 2000), even though it is not often used. Our ethnopharmacological survey demonstrated that A. maculatum is a promising plant for treatment of hemorrhoids and even preferable than the surgery which is so far considered the definitive treatment (Kochmarov et al 2015). Therefore the problem for the plant resources is crucial. Our survey on the natural distribution of the genus Arum in Bulgaria (Kozuharova et al. 2014) revealed that A. maculatum occurs only in eight floristic regions – data collected by literatur…
Biodiversity of wood-decay fungi in Italy
2011
Abstract Current knowledge about Italian wood-decay fungi (Basidiomycota and Ascomycota) is surveyed: 1582 taxa belonging to Ascomycota (341) and Basidiomycota (1241) have been reported, including 23 species new to science of Basidiomycota described from Italy within the last five years. Evaluating diversity of wood-decay fungi can provide a more accurate estimation of species richness for fungi which are an important functional component of ecosystems. Aphyllophoroid and Ascomycota species play an important role in habitat conservation and management. Sardinia, Sicily, the Alps and the Apennines are “hot spots” for wood-decay Basidiomycota in Italy.
New records of Asteraceae for the non-native flora of Tunisia and north Africa with some nomenclatural remarks
2022
International audience; Sixteen new Asteraceae are added to the non-indigenous flora of Tunisia. Six of them (Dimorphotheca ecklonis, Gaillardia pulchella, Gazania linearis var. linearis, Guizotia abyssinica, Rudbeckia triloba and Tithonia diversifolia) are also new for the flora of North Africa. Chrysanthemum morifolium is here first reported for the Mediterranean Basin. Seven genera (Argyranthemum, Bidens, Dimorphotheca, Gaillardia, Guizotia, Rudbeckia and Tithonia) are recorded for the first time for the vascular flora of Tunisia. Most of these species escaped from gardens and pots and became casual along roadsides and/or disturbed areas after cypsela dispersion (except for Chrysanthemum…
Azorella compacta (Yareta):an endemic plant of the Andean planteaux in South America. Azorella compacta (Yareta): pianta endemica degli altipiani and…
2013
Azorella compacta (Yareta): pianta endemica degli altipiani andini del Sud America. – Si riportano i risultati di una ricerca sugli usi della Azorella compacta Phil da parte delle popolazioni sudamericane del Perù, Argentina, Cile e Bolivia, allo scopo di realizzare una documentazione etnobotanica di partenza per possibili applicazioni pratiche della pianta. La sperimentazione sulla A. compacta ha preso in esame lo stato attuale di conservazione, la classificazione e descrizione botanica, l’ecologia, la distribuzione, l’utilizzazione in etnomedicina e etnofarmacologia e altre possibili impieghi. Dalla suddetta esperienza è emerso che tutte le comunità in studio,dei suddetti Paesi, utilizzan…
LE SPECIE DELLA FLORA VASCOLARE SICILIANA INCLUSE NELLE NORMATIVE INTERNAZIONALI
2012
Species of sicilian vascular flora included in the international laws. The present paper aims to divulgate the knowledge of the Sicilian flora protected at international level and includes a check-list of the Sicilian vascular flora recorded in international normatives on the protection of nature and biodiversity. For each normative general information is given together with a reference list to further deepen the contents, the aims and the present implementation in Italy.
Plant invasion risk inside and outside protected areas: Propagule pressure, abiotic and biotic factors definitively matter
2023
Invasive alien species are among the main global drivers of biodiversity loss posing major challenges to nature conservation and to managers of protected areas. The present study applied a methodological framework that combined invasive Species Distribution Models, based on propagule pressure, abiotic and biotic factors for 14 invasive alien plants of Union concern in Italy, with the local interpretable model-agnostic explanation analysis aiming to map, evaluate and analyse the risk of plant invasions across the country, inside and outside the network of protected areas. Using a hierarchical invasive Species Distribution Model, we explored the combined effect of propagule pressure, abiotic …

Indagine fitosociologica sulle praterie a Brachypodium retusum (Pers.) Beauv. della Sardegna.
2005
The grasslands characterized by the dominance of Brachypodium retusum occurring in Sardinia are examined. These communities, belonging to the Thero-Brachypodion ramosi alliance (Lygeo-Stipetea class), are quite widespread in the Island, where they usually grow on carbonate substrata from the sea level up to 1300 m of altitude. On the basis of several phytosociological relevés, it has been possible to recognize six associations well-differentiated from the floristic, ecological and syndynamic point of view. The autonomy of these associations is also supported by a numerical multivariate analysis based on quantitative data (dendrogram and P.C.A.). The associations surveyed are the following: …
Estudio anatómico-histológico de las flores del endemismo Lamottea diania (Asteraceae) y de los efectos del ozono troposférico sobre su desarrollo.
2016
"Estudio anatómico-histológico de las flores del endemismo Lamottea diania (Asteraceae) y de los efectos del ozono troposférico sobre su desarrollo". Lilloa 53 (2). Plantas del endemismo Lamottea diania se expusieron en cámaras OTC (Open Top Chambers) a aire ambiente filtrado y a aire ambiente no filtrado más 30 ppb de ozono para observar el efecto de este contaminante sobre el desarrollo de sus flores, particularmente sobre su androceo. Hemos comprobado, mediante estudios de microscopía óptica y electrónica, que el ozono afecta el proceso de desarrollo y maduración de los estambres y del polen. Las anteras se ven afectadas, en unos casos al abortar algunos estambres en su desarrollo y, en …
