A new species ofCentaurea(Asteraceae) from Sicily
2008
A new species of Centaurea, Centaurea sicana, endemic to Sicily, is described. This new taxon is close to Centaurea parlatoris and Centaurea giardinae (Sect. Dissectae), the former occurring at Palermo and in the Madonie Mountains, while the latter occurs on the Etna volcano. The new species has so far been found only on the Sicani Mountains, a limestone mountain range in western Sicily, while the related species occur in the surrounding mountains. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 157, 785–788.
COMPOSITION OF THE ESSENTIAL OILS IN CALENDULA SUFFRUTICOSA (ASTERACEAE) FROM SICILY
2016
The genus Calendula L. (Calenduleae Cass., Asteraceae) includes several species having medicinal properties. Pharmacological studies reveal, for instance, that C. officinalis L. exhibits antibacterial, antiviral, antinflammatory, antitumor and antioxidant properties; C. arvensis L. has antibacterial, antinflammatory, antimutagenic and haemolytic activities; C. suffruticosa Vahl has antimicrobial activity, especially against pathogenic microorganisms as Pseudomonas syringae Van Hall, Pseudomonas fluorescens (Flügge) Migula, Xanthomonas campestris (Pammel) Dowson and Agrobacterium tumefaciens Smith & Townsend. Nevertheless, despite a long tradition of use of the above species, and others,…
Materiały do znajomości ryjkowców (Coleoptera: Curculionoidea) Beskidu Wschodniego
2017
The paper presents new data on the distribution of the superfamily Curculionoidea in the Eastern Beskidy Mountains. The study was carried out between 2003 and 2015 in the south-western part of this region. A list of 134 species of Curculionoidea classified into 7 families (Anthribidae, Attelabidae, Rhynchitidae, Nanophyidae, Apionidae, Curculionidae, Erirhinidae) is presented. Some of them are rare in Poland or have been collected in this region for the first time: Chonostropheus tristis, Aspidapion validum, Barynotus moerens, Dodecastichus inflatus, Otiorhynchus obsidianus, Lixus punctiventris, Tachyerges rufitarsis and Lignyodes suturatus.
Contributo alla conoscenza floristica dei monti Sicani (Sicilia): resoconto dell’escursione del Gruppo di Floristica (S.B.I.) nel 2012
2015
The results of the excursion of the “Gruppo di Floristica” of the Italian Botanical Society held in the Sicani Mountains (CW-Sicily) on May 3-6, 2012, are here presented. During the research a total of 532 taxa was recorded. Three of them, the native Rosa squarrosa and the alien Phyllostachys aurea and Vitis ×koberi are new to Sicily, and 14 are new to the Sicani Mts. On the other side, we confirm the exclusion of Erica manipuliflora from the flora of the region.
Analysis of the bryophyte diversity of mountain ranges in Sicily.
2015
The focus of this study was an analysis of the bryophyte flora of the main Sicilian mountain ranges, i.e., Peloritani, Nebrodi and Madonie mountains, located along the northern side of the Island, the Sicani mountains, located in the west-central Sicily and the Etna, the highest and most active volcano of Europe. The overall bryoflora consists of 504 taxa, 400 mosses and 104 liverworts and hornworts. It represent the 85.3% of the whole Sicilian flora; the mosses are referred to 37 families, the liverworts together with hornworts to 31 families. The phytogeographical analysis has shown the prevalence of the Mediterranean species, with the highest value on the Sicani mountains. It is notewort…
The landscape of the manna ashes in Sicily
2009
The manna ashes are related to wild species of the genus Fraxinus, namely F. ornus (true manna ash) and F. angustifolia (narrow leaved ash). About two centuries ago, several varieties of such species, selected in ancient times, were widely cultivated for extracting the manna drug. This represented a remarkable economic resource for the region. Manna was extracted mainly for pharmacological industry, but today it has became a herbal product. Irrespective of the processes that reduced this cultivation to the lowest extent, the manna ash landscape is a remarkable peculiarity in the frame of the Mediterranean agrosystems. It is still kept alive as a relict cultivation within a very restricted a…
Borders on the old maps of Jizera Mountain
2019
Abstract Old maps, mainly from the period between 1890 and 1940, have been collected in the framework of the project “Old Maps of the Jizera Mountains”. These maps provide us with a complex picture, mainly of tourism, in this currently Czech–Polish territory. The territory of the Jizera Mountains was inhabited mainly by a German-speaking population on both sides of the border until 1945. Yet it is interesting to examine how the border between the two states – in those times Czechoslovakia and Germany, now Czechia and Poland – was illustrated on these old maps. This article argues that the border was not perceived as a barrier as such until later on, mainly due to the ethnic change in the bo…
Geomorphological setting of Madonie Geopark (Italy)
2006
The Madonie Natural Park is characterized by relevant zoological and botanic aspects and by geological features so remarkable that since 2001 it has been incorporated into the European Geoparks Network. The Park is marked by a wide massif know as Madonie Mountains. In this area, segment of the Maghrebide-Apenninic chain, successions of Meso-Cenozoic lithologies and late- and post-orogenic deposits occur. The geomorphological setting is extremely varied and includes many landscapes characterising several Sicilian areas; it results from the interaction between geomorphological processes, tectonic movements and climatic changes. It is possible to identify five distinct sectors, each correspond…
Genome-wide association study for refractive astigmatism reveals genetic co-determination with spherical equivalent refractive error: the CREAM conso…
2015
To identify genetic variants associated with refractive astigmatism in the general population, meta-analyses of genome-wide association studies were performed for: White Europeans aged at least 25 years (20 cohorts, N = 31,968); Asian subjects aged at least 25 years (7 cohorts, N = 9,295); White Europeans aged <25 years (4 cohorts, N = 5,640); and all independent individuals from the above three samples combined with a sample of Chinese subjects aged <25 years (N = 45,931). Participants were classified as cases with refractive astigmatism if the average cylinder power in their two eyes was at least 1.00 diopter and as controls otherwise. Genome-wide association analysis was carried out for …
Pre‐instrumental summer precipitation variability in northwestern Greece from a high‐elevation Pinus heldreichii network
2021
The spatiotemporal variability of precipitation is of vital importance to Mediterranean ecology and economy, but pre‐instrumental changes are not well understood. Here, we present a millennial‐length June–July precipitation reconstruction derived from a network of 22 Pinus heldreichii high‐elevation sites in the Pindus Mountains of northwestern Greece. Tree‐ring width chronologies from these sites cohere exceptionally well over the past several hundred years (r1467–2015 = 0.64) revealing coherence at inter‐annual to centennial timescales across the network. The network mean calibrates significantly against instrumental June–July precipitation over the past 40 years (r1976–2015 = 0.71), even…
