La flora briofitica dell’area archeologica di Selinunte (Sicilia sud-occidentale).

2018

The bryophyte flora settled on the ancient ruins and other habitats of the archaeological area of Selinunte has been studied. The study showed that the bryophyte flora consists of 51 specific and infraspecific taxa (44 mosses and 7 liverworts). The analysis points out that the bryophyte flora of Selinunte is the richest from the taxonomic point of view. moreover, it is characterized by a prevalence of mediterranean taxa and has a distinctly photophilous, thermophilous, xerophilous and calcicolous-neutrophilous connotation. Biodeteriogenic species potentially more dangerous for their spread, abundance and reproductive capacity are highlighted.

Genetic variations in the endangered Sicilian endemic Brassica rupestris: proposals for a conservation strategy

2012

Brassica rupestris Raf. is a chasmophyte species that includes two subspecies, both endemic to Central-Western Sicily (Italy). Inter-Simple Sequence Repeat (ISSR) markers were used to detect genetic diversity within and among eight populations representative of the species' distribution range. High levels of genetic diversity were revealed both at the population (PPB = 53.88%, HS = 0.212, Sh = 0.309) and at the species level (PPB = 96.55%, HT = 0.307, Sh = 0.464). The correlation between genetic and geographical distances was negative (Mantel test, r = -0.06, P < 0.95). The two subspecies of B. rupestris, subsp. rupestris and subsp. hispida, showed remarkable genetic similarity and molec…

Wood-decay fungi on trees of the city of Palermo (Sicily, Italy)

2020

Nineteen taxa, belonging to 15 genera, included in 12 families of Basidiomycetes were observed on different living trees and stumps. Data on hosts and collection sites are reported together with notes on the causes of wood decay fungi attack and suggestions for solutions.

Hieracium pallidum subsp. aetnense (Asteraceae), a new subspecies from Sicily (Italy), with notes on the taxonomy of H. pallidum Biv.

2013

Hieracium pallidum subsp. aetnense Gottschl., Raimondo & Di Grist. is described and illustrated. H.pallidum is considered as an intermediate species between H. schmidtii and H. racemosum (“schmidtii>racemosum”) and is placed in H. sect. Grovesiana. By consequence, H.lanudae Gottschl. is transferred to H. pallidum as H. pallidum subsp. lanudae (Gottschl.) Gottschl., Raimondo & Di Grist. A key for the three recognised subspecies of H. pallidum is provided.

Plant landscape and phytodiversity in the archeological area of Segesta (NW Sicily)

2018

In the system of Sicilian archaeological parks, the area of Segesta - an ancient city of western Sicily referring to the Carthaginian eparchy, - represents, together with Selinunte, Erice and Mothia, another integrated hotspot of biodiversity and archeaology. The current plant landscape is strongly influenced by a millenary anthropic transformation. There are no residual expressions of the original plant covering that, with reference to the environmental potential of the area, can be traced back to the evergreen Mediterranean forest dominated by Quercus ilex, presently only sporadically occurring in the area of the ruins, together with other species related to associations and upper syntaxa…

An updated checklist of the vascular flora alien to Italy

2018

An updated inventory of the vascular flora alien to Italy, providing details on the occurrence at regional level, is presented. The checklist includes 1597 species, subspecies, and hybrids, distributed in 725 genera and 152 families; 2 taxa are lycophytes, 11 ferns and fern allies, 33 gymnosperms, and 1551 angiosperms. 157 taxa are archaeophytes and 1440 neophytes.

A newCentaureaspecies (Asteraceae) from Mt Sakar, South-eastern Bulgaria

2013

A new species of Centaurea, C. sakarensis, known from a single locality north-east of the village of Lessovo on Mt Sakar, is described and illustrated. It belongs to C. sect. Acrolophus, and its morphologically closest relative is C. cariensis Boiss., a Turkish endemic from western and south-western Anatolia. The new species is currently known from a single population of about 1000 individuals, growing on open stony calcareous places, at 475 m a.s.l., and should be classified as Critically Endangered, (B1ab[i, ii, iii]+2ab [i, ii, iii]).

Pseudoamblystegium subtile (Hedw.) Vanderp. & Hedenäs. CONTRIBUTORS: R. Gabriel, M. Kubová, C. Sérgio and I. Soares Albergaria. PORTUGAL, AZORES: Terceira Island, Angra do Heroísmo, municipal garden ‘Jardim Duque da Terceira’, 38° 39′ 24.0′′N, 27°13′ 05.99′′W, 31 m a.s.l, on the base of a shrub, in acidic conditions, 7 April 2017, leg. Michaela Kubová s.n. (AZU). A new understanding of the pleurocarpous moss species Pseudoamblystegium subtile was proposed by Vanderpoorten and Hedenäs (2009). The new genus is separated from the other Amblystegiaceae primarily due to its phylogenetic consistency and is characterised by the possession of leaves with a very short nerve, and erect capsules (Vand…

An updated checklist of the vascular flora native to Italy

2018

An updated inventory of the native vascular flora of Italy, providing details on the occurrence at regional level, is presented. The checklist includes 8195 taxa (6417 species and 1778 subspecies), distributed in 1092 genera and 152 families; 23 taxa are lycophytes, 108 ferns and fern allies, 30 gymnosperms and 8034 angiosperms. The taxa currently occurring in Italy are 7483, while 568 taxa have not been confirmed in recent times, 99 are doubtfully occurring in the country and 19 are data deficient. Out of the 568 not confirmed taxa, 26 are considered extinct or possibly extinct.

A study of the hydrophyte communities of some small ponds in the beech-wood belt of the higher Nebrodi Mts is presented. A new association of shallow stagnant water bodies, the Utriculario-Potametum natantis, is described. Its biological structure, biogeographical characteristics, syntaxonomic position, phytosociological relationships and dynamic links are discussed.

Stipa valdemonensis (Poaceae), a new species from Sicily

2012

A new species of Stipa, endemic to Sicily, is here described and named Stipa valdemonensis. The new taxon is related to S. crassiculmis. Owing to the small number of individuals observed, in few restricted localities only, it is assigned the IUCN threat status “vulnerable”

Environmental quality assessment of the Sicilian coast using a multi-disciplinary approach

2018

A multidisciplinary approach for the assessment of the environmental quality of the Sicilian coast is presented. This approach can be adopted for any Mediterranean coastline. The territory was divided into elementary areas and for each of them we reported the most important taxa, belonging to fauna and vascular, bryophytic and algal flora, from a biogeographic point of view in order to evaluate punctual and general levels of biodiversity conservation. The comparative analysis showed that the main circumsicilian islands and the carbonate promontories of the Tyrrhenian coast present the highest degree of biodiversity. The coastal lagoons located in the south-eastern Sicily, even though charac…

Project for a Sicilian Bryophyte Red List.

2016

Due to its location, Sicily has always represented an important biogeographic bridge between floras of temperate and tropical climates as well as between those of the western and eastern Mediterranean. Its central position in the Mediterranean was also key factor of a millenary history of human settlements which resulted in profound landscape changes in the past, but even at present human pressure continues to be very heavy. In spite of this, Sicily is part of one of the 10 most important hotspots in Mediterranean Basin, thanks to plant richness and endemism (Médail & Quézel 1999: Conserv. Biol. 13(6): 1510-1513). The bryophyte flora, including ca. 600 taxa (almost half of Italian bryof…

PESI - a taxonomic backbone for Europe

2015

Reliable taxonomy underpins communication in all of biology, not least nature conservation and sustainable use of ecosystem resources. The flexibility of taxonomic interpretations, however, presents a serious challenge for end-users of taxonomic concepts. Users need standardised and continuously harmonised taxonomic reference systems, as well as highquality and complete taxonomic data sets, but these are generally lacking for nonspecialists. The solution is in dynamic, expertly curated web-based taxonomic tools. The Pan-European Species-directories Infrastructure (PESI) worked to solve this key issue by providing a taxonomic e-infrastructure for Europe. It strengthened the relevant social (…
