Agarose/κ-carrageenan-based hydrogel film enriched with natural plant extracts for the treatment of cutaneous wounds.
2020
Abstract Hydrogels for complex and chronic wound dressings must be conformable, absorb and retain wound exudates and maintain hydration. They can incorporate and release bioactive molecules that can accelerate the healing process. Wound dressings have to be in contact with the wound and epidermis, even for long periods, without causing adverse effects. Hydrogel dressing formulations based on biopolymers derived from terrestrial or marine flora can be relatively inexpensive and well tolerated. In the present article hydrogel films composed by agarose (1.0 wt%), κ-carrageenan at three different concentrations (0.5, 1.0 and 1.5 wt%) and glycerol (3.0 wt%) were prepared without recourse to cros…
Bryophytes as ecological indicators in the beech woods of sicily
2019
Beech woods, which have in Sicily one of the southernmost places of their distribution area, are localized in the mountain belt of North and North-Eastern Sicily, at an altitude of 1300-1900 m, reaching 900 m on the Peloritani. They are referred to the priority habitat 9210*, according to the Natura 2000 network of the European Union. Beech woods settle on different soils, such as incoherent sandy volcanic (Etna), calcareous or silico-arenaceous (Madonie) and clayey-schistose soils (Nebrodi and Peloritani). Bryophytes are considered important components of forestry ecosystems. Many of these organisms are specific to particular types of microhabitats and sensitive to changes such that specie…
Bryophytes collected during the 12th “Iter Mediterraneum” (Tunisia, 24 March – 4 April, 2014). First contribution
2015
Part of the bryophytes collected during Iter Mediterraneum XII is listed. Some noteworthy species were found: Dicranella howei, had so far been recorded only doubtfully from Tunisia; Funaria hygrometrica, Grimmia laevigata, Grimmia trichophylla, Imbribryum alpinum, Pogonatum nanum, Rhynchostegium riparioides, Scleropodium touretii, Scorpiurium circinatum, Thamnobryum alopecurum, Timmiella barbuloides, Tortella squarrosa, Tortula muralis and Tortula vahliana, had not been reported from that country for more than half a century.
An analysis of the bryophyte flora in Sicilian archaeological areas
2019
An analysis of the bryophyte diversity in the studied Sicilian archaeological areas was conducted, highlighting which species are more common and potentially harmful on the ruins. The floras are much diversified and the presence of some rare taxa highlights the role of refuge carried out by these areas, especially for the species of strongly threatened coastal habitats. Attention on the complexity of the relationships between restoration interventions on lithic structures and conservation needs of the rare and interesting taxa is point out.
A first contribution to the cryptogamic flora of “Bosco Pomieri” (Northern Sicily)
2020
This is the first contribution to the cryptogamic flora (algae, bryophytes, fungi and lichens) of the “Bosco Pomieri”, an old-growth forest included in the Madonie Regional Park (N-Sicily). This area presents a significantly high biodiversity (41 algae, 41 bryophytes, 141 fungi, and 105 lichens) and also hosts several taxa of high biogeographic value.
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…
A survey of the epiphytic bryophyte flora of the Rif and Tazzeka Mountains (northern Morocco)
2005
SUMMARY The catalogue of the epiphytic bryophyte flora of the Rif Mountains includes a total of 72 taxa, of which 66 are mosses and six are liverworts. Some new records are provided: Hypnum resupinatum and Tortula israelis, new to northern Africa, Antitrichia curtipendula and Cryphaea heteromalla, new to Morocco, and Dicranoweisia cirrata, Isothecium alopecuroides and Orthotrichum macrocephalum ,n ew to the Rif Mountains. Epiphytic communities in the different forest types have been analysed, with the conclusion that altitude and humidity are the main factors that determine their composition. The epiphytic stratum is best developed at the highest altitudes on the Principal chain and Tazzeka…
Plagiochasma appendiculatumLehm. & Lindenb. (Marchantiales, Aytoniaceae), a species new to the European bryophyte flora
2005
Abstract The liverwort Plagiochasma appendiculatum Lehm. & Lindenb. is reported for the first time in Europe from Mallorca (Balearic Islands, Spain). The species is described and illustrated and its distribution and ecology are discussed. Plagiochasma appendiculatum differsfromP. rupestre (J. R. Forst. & G. Forst.) Steph., the only species of the genus known at present in Europe, by characters such as the bright green or green-yellowish thallus and the orbicular and obtusescale appendages which are markedly constricted and folded at the base.
Additional reports for Italian moss flora.
2013
As a result of the study of both recent collections and a review of herbarium specimens, the following taxa are reported for the first time from various Italian regions: Hedwigia stellata Hedenas, Hedwigia ciliata var. leucophaea Bruch & Schimp., Pleurozium schreberi (Willd. ex Brid.) Mitt. and Ptychostomum compactum Hornsch. var. compactum. The last taxon is new for southern Italy, while the report of Pleurozium schreberi confirms the occurrence of this species in southern Italy after more than half a century. Moreover, Crossidium laxefilamentosum Frey & Kurschner represents the second report of this species from Italy.
