Seed germination data of three Hieracium and one Pilosella (Asteraceae) from Sicily and southern Italy
2020
This work reports the first seed germination data of three Hieracium and one Pilosella (Asteraceae) taxa from Sicily and southern Italy. The studied taxa are: Hieracium hypochoeroides subsp. cilentanum, endemic to Campania, H. schmidtii subsp. nebrodense, endemic to Sicily, H. terraccianoi, endemic to Calabria and Pilosella hoppeana subsp. sicula, endemic to Sicily. The obtained results showed that the investigated taxa produce non-dormant seeds, with a high percentage of germination at all tested thermoperiods (15°C to 25°C and the alternating temperature of 25/15°C). Germination tests carried out in gibberellic acid (GA3) provided similar germination percentages. The data presented in thi…

Towards the identification of species-specific monitoring protocol for the Italian flora of Community interest
2016
The ongoing activities for the identification of monitoring methods for the Italian flora of Community interest (FCI) are presented. The reference framework is the Directive 92/43/EEC. Monitoring is an obligation arising from Art. 11 and the results have to be reported every six years, according to Art. 17. In the last Italian National Report, covering the period 2007-2012, the status of the FCI was assessed using available knowledge and expert judgment, still revealing relevant lack of data for some plant species and, in turn, population parameters (Ercole and Giacanelli, 2014). To overcome these deficiencies, in 2015 began a project aims to set future monitoring activities and to optimize…
Drafting a prioritized checklist of Crop Wild Relatives and Wild Harvested Plants of Italy: problems and solutions
2022
The National checklists of Crop Wild Relatives (CWR) and Wild Harvested Plants (WHP) are the basic tools for the development of in situ and ex situ conservation strategies of plant genetic resources. Here we discuss the methodologies and the prioritization process we previously used in the preparation of the prioritized checklist of CWR and WHP for Italy. The starting point were the most up-to-date Italian checklists of native and alien flora with their updates used as a nomenclatural and distributive source of data. Sardinia and Sicily were kept separate from peninsular Italy to perform detailed analyses focused on the taxa of the two major islands. The origin, the endemic status, cultivat…
CONSERVATION STATUS ASSESSMENT OF THE ENDEMIC HIERACIUM S. STR. (ASTERACEAE) OCCURRING IN SICILY
2022
The current status of the majority of apomictic taxa, and therefore their priorities for conservation, are poorly known, and consequently, they are neglected by conservationists. In Sicily 8 species and 4 subspecies of Hieracium s. str. occurs. Eleven taxa are endemic to the area, one has a wider distribution. These taxa were not evaluated within the recent project “Red List assessment of plants and fungi in Italy” because collectively considered with insufficient and unreliable distribution data. The global conservation status of the endemic Hieracium s. str. taxa occurring in Sicily was assessed here using the IUCN categories and criteria, on the basis of the data collected during field s…
BIOAEROSOL IN INDOOR ENVIRONMENTS FOR CONSERVATION OF CULTURAL HERITAGE: POTENTIAL RISKS FOR HISTORICAL-ARTISTIC MANIFACTS ANO HUMAN HEALTH
2014
An integrated approach was applied for the characterization of the biological airborne particulate in four Sicilian sites with peculiar structure, thermo-hygrometric and lighting parameters. We focalized the attention on: ,) Crypt in the Cathedral Treasury Museum (Palermo), an underground environment (lithic and stone artifact), daily visited by tourist and characterized by a reduced indoor-outdoor exchange; it) the Saints Cave in Licodia Eubea (Catania), a semi-confined environment (fresco), strongly influenced by the surrounding countryside and by a continuous airflow; iit) the Diocesan Historic Archive in Palermo, (documentary funds, IX-XXsec.), characterized by low air change rate and r…
La scelta delle piante destinate al verde ornamentale tra percezioni e cambiamenti: Anthosart green tool, uno strumento per conoscere, selezionare, a…
2019
The presence and importance of plant life on the planet does not seem to reach our sensory perception, therefore activate reactions of interest, and correct ecological behaviour. The increasing number of extinct species witnesses the human oblivion towards ecosystems. The concept of plant blindness describes the phenomenon that produces significant consequences on nature conservation. Urban green infrastructure, part of our daily life, is the right place to re-connect with plant systems. Designing and creating “built green” by means of nature-based solutions and local species pool is the main goal of Anthosart green tool, a free and user-friendly on-line tool, which can be useful for design…
Schede per la flora ornamentale siciliana. 61-67
2013
With the aim to improve the knowledge of the ornamental flora of Sicily, a series of reports on the most rare and significant species found in the historic or public gardens and parks has been started since 2001. The plants taken in consideration are examined as far as taxonomy, geographical origin, biology, ecology are concerned, also taking into account their condition in Sicily with respect to introduction, sanitary status, occurrence, etc... Furthermore, germplasm conservation is, when possible, provided in the Botanical Garden of Palermo. Each taxon is treated in a single report. Here the reports 61-67, by F. Argento, M.R. Cucco, E. Di Gristina & R. Oliveri, are presented. These concer…
All hands on deck: An innovative approach to sustained and sustainable conservation funding for endangered plants and ecosystems
2022
The Red List Project (TRLP) was founded in 2018 as an NGO [501(c)(3)], dedicated to preventing the extinction of the world's most endangered plant species and to protecting biodiversity hotspots. This approach is highlighted by an ongoing partner ship between TRLP, independent fragrance house Baruti Perfumes and the University of Palermo, to prevent the extinction of the Viola ucriana Erben and Raimondo, critically endangered. This violet is restricted to the slopes of Mt Pizzuta in the Serre della Pizzuta Nature Reserve in Sicily (Italy), between 950 and 1300 m s.l.m., where it grows in xeric prairies and is threatened by factors partly related to human disturbance (e.g., fires, grazing, e…
Su un erbario del XVII secolo conservato presso il Museo Regionale di Messina: Stato di conservazione e proposte per il recupero e la salvaguardia
2013
In this article the conservation status of a XVII Century herbarium from Messina is assessed. This herbarium is attributed to Pietro Castelli, the founder of the Botanical garden of Messina or, most probably, to a pupil of him. It consists of a single volume of 214 pages and is housed in the library od the Museum “Maria Accascina” in Messina. The large part of the specimens stay in poor conditions. Hypothesis for recovery and preservation both in short and long term of this precious heritage are given.
