Mediterranean Gardens from Sicily to Malta

2012

This publication is one of the expected results of the European porject GARDMED (PO Italy- Malta 2007-2013). It aims to bring people to discover the Mediterranean gardens, highlighting the great botanical diversity, the history, the artistic, cultural and natural heritage.

Proposal to conserve the name Orobanche foetida (Orobanchaceae)

2015

In this Proposal we formally propose to conserve O. foetida with Bourgeau’s gathering of 16 April 1856 as conserved type. Our choice rests on the following reasons: (1) it clearly represents the current usage of the name O. foetida; (2) it is based upon material from northern Algeria not far from the Algerian-Tunisian border where the ranges of the two species overlap and in a region broadly coincident with the original terra classica of Poiret’s name; (3) the proposed conserved type is readily accessible online in a remarkably detailed digitization; (4) the sheet contains a sample of the host plant, which proves to be a non-shrubby Fabaceae (presumably Medicago laciniata (L.) Mill.) and th…

INVESTIGATION ON OLD-GROWTH FORESTS OF SICILY: PRELIMINARY RESULTS

2014

Old-growth forests are natural forests that have developed over a long period of time, without experiencing severe, stand-replacing disturbance a fire, windstorm, or logging. According to UNEP/CBD/SBSTTA definition, an old-growth forest is a primary or a secondary forest which has achieved an age at which structure and species normally associated with old primary forests of that type have sufficiently accumulated to act as a forest ecosystem distinct from any younger age class. In a thematic contribution to the National Biodiversity Strategy, the authors report the following definition of Italian old-growth forests: Forest in which human disturbance is absent or negligible, and in which nat…

Forest ecosystems in the Monti Sicani Park (Sicily)

2022

The authors analysed the forest ecosystems in the Monti Sicani Park (Sicily). In particular, the state of the natural and non-native forests in the Site of Community Interest (SCI ITA040005) - Monte Cammarata, Contrada Salaci, was evaluated in terms of distribution, evolution of forest dynamics and, silvicultural activities. The evolution of vegetation within two different forest plots are analysed and management strategies are proposed. The finding on Mount Cammarata of seedlings of Fagus sylvatica in the undergrowth of a conifer afforestation is noteworthy.

First record of Euphorbia graminea (Euphorbiaceae) in Italy

2016

Euphorbia graminea Jacq. (Euphorbiaceae), a species native from Central America through northern South America, from Northern Mexico to Peru, has been found naturalized near Palermo (Sicily). This is the first record for Italy and Europe

Pleurotus nebrodensis, a very special mushroom

Verifica dei luoghi storici di raccolta di Pleurotus nebrodensis (Basidiomycota)ai fini di una valutazione dello stato del popolamento

2009

Nel 1902, Ferdinando Alfonso Spagna, direttore dell’Istituto Agrario Castelnuovo e redattore dei Nuovi Annali di Agricoltura Siciliana, è autore di una pubblicazione dal titolo “Dei funghi velenosi” (1) nella quale include un “elenco minuzioso dei funghi mangerecci più comuni” al fine di fornire indicazioni utili ai cercatori di funghi e per evitare i frequenti avvelenamenti che, a quel tempo, avevano causato numerose vittime in varie regioni d’Italia. Alfonso Spagna, tra le specie eduli e di buone proprietà organolettiche, segnala Pleurotus nebrodensis [sub: Agaricus nebrodensis Inz.], “fungo di eccellenti qualità”, noto localmente con il nome di “fungo di basilisco”. A differenza di Giuse…

Invasive Amphisteginids conquer the Sicily Channel and knock on the door of the Western Mediterranean Sea

2018

This study reports an updated overview of the current distribution and establishment status of the invasive species Amphistegina lobifera Larsen, 1979 and of other non-indigenous foraminifera in the Sicily Channel. The dispersal of marine non-indigenous species (NIS) by human activities is redefining the biogeography of the oceans and is one aspect of global change. Understanding the role of NIS in altering the structure of marine communities requires accurate information on their temporal occurrence, spatial distribution and effect on native ecosystems. However many NIS, particularly those belonging to small-sized unicellular taxa, such as benthic foraminifera, are largely unrecognized and…

Antimicrobial Activity of the Desert Truffles "Tirmania pinoyi" and "Terfezia claveryi" Against Human Pathogens

2015

The development of novel antimicrobials in the struggle against pathogens and antibiotic resistance is one of the most important global challenges of our time. Medicinal mushrooms represent an unlimited source of polysaccharides with nutritional, antitumoral, antibacterial and immune stimulating properties1. In recent years the traditional studies on epigeous higher Basidiomycetes have been joined by those on hypogeous fungi and in particular on the so-named “desert truffles”. Ali2 demonstrated that organic extraction of truffles of genus Tirmania and Terfezia possess antimicrobial activity with broad-spectrum effects against Gram positive, Gram negative, aerobic and anaerobic bacteria …
