Land unit definition for potential distribution of endangered species
2010
In Europe several mapping techniques exist to lay out plant distribution. Most of them, however, are focused on actual and not on potential species distribution range. Spatial predictions become more important for rare and endangered taxa because their conservation is related to existing as well as potential biotopes. The large part of detailed distribution models applies advanced statistics on a large data-set of environmental variables. Data-input availability limits the choice of the prediction model for species distribution and application of results in a detailed scale. Distribution pattern accuracy determinates its applicability in environmental management (for tracing edges, defining…
The chemical composition of the aerial parts essential oil of Acinos alpinus subsp. nebrodensis (Lamiaceae) growing in Sicily (Italy)
2021
Acinos is a small genus of economically important plants belonging to Lamiaceae family whose botanical collocation is quite problematic due to the disagreement among the botanists and the presence in literature of several names and synonyms from different sources. In the present study the chemical composition of the essential oil from aerial parts of Acinos alpinus subsp. nebrodensis (Strobl) Brullo & Brullo collected in Central Sicily was analyzed by GC-MS. The result showed the presence of large quantity of sesquiterpene hydrocarbons with germacrene D (37.9%) as the most abundant component followed by (E)-β-caryophyllene (5.1%). Among the oxygenated monoterpenes thymol (8.3%) was the …
Taxonomic identity, geographic distribution and commercial exploitation of the culinary-medicinal mushroom Pleurotus nebrodensis
This work provides an updated overview of an investigation carried out in Europe and elsewhere on the culinary-medicinal mushroom Pleurotus nebrodensis. In particular, the taxonomic identitiy of P. nebrodensis and other related oyster mushrooms with entirely white to cream basidiomata that grow on different plants of the family Apiaceae, is clarified. The differences in the cultivation techniques, the quality of product sold and the sales price in Europe and Asia are also highlighted. Taking also into consideration the importance of P. nebrodensis from the medicinal point of view, it appears appropriate to proceed with a verification of the commercial strains currently available in the inte…
Genetic polymorphism and taxonomic infrastructure of the Pleurotus eryngii species-complex as determined by RAPD analysis, isozyme profiles and ecomo…
2001
The Pleurotus eryngii species-complex includes populations of choice edible mushrooms, growing in the greater Mediterranean area in close association with different genera of plants of the family Apiaceae. Their distinct host-specialization served as the principal criterion for the discrimination of several taxa; however, the genetic relationships among the various P. eryngii ecotypes remain ambiguous. In the present study, 46 Pleurotus strains with a wide range of geographical origins were isolated from Eryngium spp., Ferula communis, Cachrys ferulacea, Thapsia garganica and Elaeoselinum asclepium subsp. asclepium, and were subjected to isozyme and random amplified polymorphic DNA-PCR (RAP…

Chemodiversity of the essential oil from leaves of Abies nebrodensis (Lojac.) Mattei
2016
As activities of the project "Preservation of Abies nebrodensis and restore of Geraci Siculo peatlands", the chemical composition of essential oils, obtained from leaves of Madonie fir, was compared with the ones of essential oils derived from Eurasian species studied up to now
Conservation of forest biodiversity in Sicily: contribution of the University of Palermo Germplasm Bank (Italy)
2017
Germplasm Banks dedicated to the wild plants seeds conservation play a unique role in integrating the in situ conservation of endemic, rare or endangered plant species. One of the missions of the Seed Bank of the University of Palermo (HBP-Bank) is to support the conservation of biodiversity with particular attention to the spectrum of genetic diversity of plants belonging to Mediterranean habitat. Abies nebrodensis (Lojac.) Mattei is an relict species, consisted of 30 natural individuals, gathered in a small area of the Madonie Natural Park in Sicily (1500 -1600 m above s.l.), recorded on the checklist “TOP 50 Mediterranean Island Plants”. It is also one of eight conifers species criticall…

MARINO Dipartimento di Biologia Ambientale e Biodiversità dell'Università, via Archirafi 38, 90123 Palermo (I) rosario.schicchi@unipa.it Abies nebrodensis è una specie endemica relitta, gravemente minacciata di estinzione, la cui popolazione naturale è costituita da 30 individui distribuiti discontinuamente in una piccola area del territorio di Polizzi Generosa, all’interno del Parco naturale delle Madonie in Sicilia. La minaccia di estinzione è dovuta, oltre all'esiguità della popolazione, al …
Un Abete da salvare
2014
Nel Parco delle Madonie, tra le montagne di Polizzi Generosa, trovano rifugio gli ultimin esemplari di Abies nebrodensis, una delle specie forestali più antiche della Sicilia. Il documentario "Un Abete da salvare" ripercorre la storia dell'unico Abete siciliano attraverso gli interventi effettuati per scongiurarne l'estinzione.
