Guida all'identificazione delle Cistoseire (Area Marina Protetta "Capo Gallo-Isola delle Femmine")
2009
Questa guida naturalistica, finalizzata alla identificazione delle specie di Cistoseire presenti nell’A.M.P. di Capo Gallo - Isola delle Femmine, è un utile strumento sia per i gestori dell’area protetta sia per i visitatori subacquei che desiderano conoscere queste specie che formano il paesaggio sommerso nel piano infralitorale ed in parte anche nel piano circalitorale. Molte delle specie, descritte in maniera semplice ed efficace, ma ben determinate, sono inserite nelle liste delle specie protette di diverse Convenzioni internazionali ed in particolare nella Convenzione di Barcellona. Pertanto la guida è anche un utile strumento per conoscere queste specie ai fini di una gestione che ne …
Charybdis glaucophylla (Asparagaceae), a new species from Sardinia
2012
Charybdis glaucophylla (Asparagaceae), a new species from Sardinia, is described and illustrated. It is a diploid species with 2n = 20 chromosomes growing along the rocky coast, sandy dunes and mountain top in the south-western part of the island. Within the genus, this species results taxonomically well isolated and differentiated due to relevant morphological and phenological features, such as the leaves wide and short, very rigid and glaucous-pruinose, as well as the very late foliation (winter). It shows only some relationships with C. pancration for the whitish bulb tunics and the diploid chromosome complement, and with C. maura and C. aphylla due to the glaucous leaves.
WILD RESOURCES OF THE PROSPECTIVE MEDICINAL PLANT ARUM MACULATUM L. IN BULGARIA
2015
Background: Arum maculatum L. (Araceae), has been known as a medicinal plant for centuries. In Bulgaria, this species is an officially acknowledged medicinal plant (Medicinal plant act 2000), even though it is not often used. Our ethnopharmacological survey demonstrated that A. maculatum is a promising plant for treatment of hemorrhoids and even preferable than the surgery which is so far considered the definitive treatment (Kochmarov et al 2015). Therefore the problem for the plant resources is crucial. Our survey on the natural distribution of the genus Arum in Bulgaria (Kozuharova et al. 2014) revealed that A. maculatum occurs only in eight floristic regions – data collected by literatur…
Biodiversity of wood-decay fungi in Italy
2011
Abstract Current knowledge about Italian wood-decay fungi (Basidiomycota and Ascomycota) is surveyed: 1582 taxa belonging to Ascomycota (341) and Basidiomycota (1241) have been reported, including 23 species new to science of Basidiomycota described from Italy within the last five years. Evaluating diversity of wood-decay fungi can provide a more accurate estimation of species richness for fungi which are an important functional component of ecosystems. Aphyllophoroid and Ascomycota species play an important role in habitat conservation and management. Sardinia, Sicily, the Alps and the Apennines are “hot spots” for wood-decay Basidiomycota in Italy.
New records of Asteraceae for the non-native flora of Tunisia and north Africa with some nomenclatural remarks
2022
International audience; Sixteen new Asteraceae are added to the non-indigenous flora of Tunisia. Six of them (Dimorphotheca ecklonis, Gaillardia pulchella, Gazania linearis var. linearis, Guizotia abyssinica, Rudbeckia triloba and Tithonia diversifolia) are also new for the flora of North Africa. Chrysanthemum morifolium is here first reported for the Mediterranean Basin. Seven genera (Argyranthemum, Bidens, Dimorphotheca, Gaillardia, Guizotia, Rudbeckia and Tithonia) are recorded for the first time for the vascular flora of Tunisia. Most of these species escaped from gardens and pots and became casual along roadsides and/or disturbed areas after cypsela dispersion (except for Chrysanthemum…
Lista bibliografica

Questa lista bibliografica contiene il secondo aggiornamento della bibliografia della Lisy e deriva dall’assemblaggio da parte della redazione (M. Serdoz ed E. Panfili) dei contributi parziali stilati dai gruppi regionali.
Typification of the name Statice calcarae (Plumbaginaceae), basionym of the threatened endemic Limonium calcarae
2018
Limonium calcarae (basionym Statice calcarae), a rare diploid species endemic to Sicily, is one of the few members of the genus that occurs in the inland areas of the island. According to IUCN criteria, it has been assessed as critically endangered but recent data on its distribution, demography and threats affecting its populations are lacking. A lectotype is designated, preserved at PAL, and isolectotypes have been traced and verified in other European herbaria.
Contribution to the knowledge of Inonotus baumii in Thailand
2015
Inonotus baumii in Thailand is reported on three new host-plants: Acacia tomentosa, Shorea robusta, and S. siamensis. A key for the identification of Inonotus species in Thailand accompanies notes on the taxonomy of I. baumii.
Traditional agrosystems trajectories analysis using a vegetation science approach: the MEMOLA EU FP7 Project as a case study
2017
The UE FP7 research project MEMOLA (Mediterranean Mountainous Landscapes: an historical approach to cultural heritage based on traditional agrosystems) aims at investigating cultural landscapes through a diachronic study of the relationship between human populations and natural resources. The project analyses from an interdisciplinary perspective the drivers and dynamics that have generated historical landscapes in four areas of Mediterranean Region (Sierra Nevada, in Spain; Colli Euganei, in Northern Italy; Monti di Trapani, in Sicily; Vjosa Valley in Albania), with a research group of ten partners. The syndynamic study of vegetation (series and geoseries) can be used as a marker to better…
Non-Indigenous Species (NIS) within Marine Protected Areas (MPAs). The case study of the Aegadian Islands MPA (Sicily, Tyrrhenian Sea) and the Dwejra…
2018
The introduction of non-indigenous species (NIS) has been pointed out as a major threat to biodiversity. NIS may become invasive alien species (IAS) and may cause biodiversity loss and ecosystem service changes. In the Mediterranean Sea, Sicily and surrounding islands, also including a high number of Marine Protected Area (MPAs), as a consequence of their geographic position and the intense maritime traffic, is a region particularly vulnerable and prone to NIS invasions. Since frontiers do not exist in the sea, biological invasions may severely affect MPAs, whose major aim is biodiversity conservation. Among the Sicilian MPAs, the Aegadian Islands MPA report the highest number of NIS (19). M…
