Typification of the name Abies nebrodensis (Pinaceae)

2017

Abies nebrodensis, endemic to the Madonie mountains (central-north Sicily), was originally described by Lojacono Pojero as A. pectinata var. nebrodensis and later raised to the rank of species. The species is considered to be critically endangered and was thought to be extinct until an extant population was rediscovered in 1957. The name is here lectotypified on a specimen preserved at NAP.

Values and challenges in the assessment of coprophilous fungi according to the IUCN Red List criteria: the case study of Poronia punctata (Xylariales…

2020

Coprophilous fungi are specialized microorganisms, playing key roles in ecosystems and in several other contexts, whose protection requires more substantial efforts. This paper aims to highlight and discuss valuable and critical aspects faced during the process of the threat status assessment of Poronia punctata, providing inspirations for future conservation actions.

Host dispersal shapes the population structure of a tick-borne bacterial pathogen

2020

Birds are hosts for several zoonotic pathogens. Because of their high mobility, especially of longdistance migrants, birds can disperse these pathogens, affecting their distribution and phylogeography. We focused on Borrelia burgdorferi sensu lato, which includes the causative agents of Lyme borreliosis, as an example for tick-borne pathogens, to address the role of birds as propagation hosts of zoonotic agents at a large geographical scale. We collected ticks from passerine birds in 11 European countries. B. burgdorferi s.l. prevalence in Ixodes spp. was 37% and increased with latitude. The fieldfare Turdus pilaris and the blackbird T. merula carried ticks with the highest Borrelia prevale…

The problem of misidentification between edible and poisonous wild plants: Reports from the Mediterranean area

2018

Abstract Today, in many European countries, people are looking for wild edible plants to experience new tastes and flavors, by following the new trend of being green and environmentally friendly. Young borage and spinach leaves can be easily confused by inexpert pickers with those of other plants, including poisonous ones, such as Mandragora autumnalis Bertol. (mandrake) or Digitalis purpurea L. (foxglove), common in southern and northern Italy respectively. In the last twenty years, several cases of intoxication by accidental ingestion of mandrake and foxglove have been reported. The purpose of this work was to perform a pharmacognostic characterization of young leaves from borage, mandrak…

Evaluation of the DNA barcoding approach to develop a reference data-set for the threatened flora of Sicily

2014

The Mediterranean Basin is one of the most significantly altered World Biodiversity Hotspots with extensive habitat loss and fast genetic population erosion, for which urgent biodiversity reconnaissance and preservation actions are required. In particular, Sicily has about 600 taxa classified as threatened or near-threatened. The correct recognition and identification of such biodiversity is required for supporting further activities. The objective of this work is to assess the ability of the DNA barcoding approach to identify different taxonomic groups from a collection of the most threatened plant taxa, throughout natural Sicilian populations. The evaluation of the DNA barcoding core mark…

Notulae to the Italian native vascular flora: 1

2016

In this contribution, new data concerning the Italian distribution of native vascular flora are presented. It includes new records, exclusions, and confirmations pertaining to the Italian administrative regions for taxa in the genera Arundo, Bromopsis, Cistus, Crocus, Festuca, Galeopsis, Genista, Lamium, Leucanthemum, Nerium, Orobanche, Peucedanum, Pilosella, Polycnemum, Stipa and Viola.

Typification of eight names in Hieracium (Asteraceae)

2012

Eight names in Hieracium (H. atrovirens Froel., H. crinitum Sm., H. lucidum Guss., H. pallidum Biv., H. racemosum subsp. todaroanum Zahn, H. siculum Guss., H. siculum var. minus Guss., H. symphytifolium Froel.), the descriptions of which are based totally or in part on Sicilian material, are typified. Hieracium racemosum subsp. todaroanum is treated as a synonym of H. crinitum, and H. siculum and H. siculum var. minus are treated as synonyms of H. symphytifolium. Hieracium atrovirens is recognized as a subspecies of H. murorum L. (H. murorum subsp. atrovirens (Froel.) Raimondo & Di Grist.).

Clarifying the nomenclature of some Euro-Mediterranean quillworts ( Isoetes , Isoetaceae): Indicator species and species of conservation concern

2018

International audience; To stabilize the application of some names in the genus Isoetes in the Mediterranean biodiversity hotspot, we studied herbarium specimens and imaged spores with scanning electron microscopy, with special reference to those taxa in the I. lon‐gissima and I. histrix groups that were described from France, Algeria and Turkey, and are in need of a taxonomic revision. The following names are lectotypified: I. adspersa, I. boryana, I. delalandei, and I. viollaei. Holotypes of I. perralderiana and I. olympica were ascertained. We conclude that I. boryana (listed in the “Bern Convention” and in the European Union “Habitats” Directive) justifies consideration at species rank,…

Volatile organic compounds in wild fungi from Mediterranean forest ecosystems

2017

AbstractHead Space-Solid Phase Micro Extraction (HS-SPME) extractions and Gas Chromatography-Mass Spectrometry (GC-MS) analysis allowed the identification of 72 different compounds isolated from 7 different wild inedible fungi collected in Mediterranean forest ecosystems. The VOCs reported in this study, including a total of 5 esters, 17 alcohols, 14 aldehydes, 9 ketones, 18 terpenes and 9 other compounds, have been never characterized before for Tricholoma ustaloides, Hygrophorus cossus, Russula foetens and Mycena pura.
