Monitoring Biological Damage on Paper-based Documents in the Historical Archive of the Palermo Astronomical Observatory

2017

Libraries and archives house a wide variety of documents made of materials of vegetal and animal origin: unbound papers and books, manuscripts and printed books, photographs (negative and positive), prints, maps, available to the public for reading needs, study and information. These materials are often subject to fluctuations in environmental and micro-environmental parameters. For this reason, it is essential to implement constant monitoring and control of environmental conditions and potential deteriogens in order to slow down deterioration processes. The monitoring of the microbial degradation of paper documents in the Historical Archives of Palermo Astronomical Observatory has revealed…

Taxonomy and conservation ofPancratium maritimum(Amaryllidaceae) and relatives in the Central Mediterranean

2015

Pancratium maritimum L. (Amaryllidaceae) is a geophyte occurring in the Mediterranean region, from the Black Sea to part of the Atlantic coast. This plant is receiving much attention from the international scientific community due to its value as a bioindicator, the potential industrial value of its chemical compounds, and its use as a commercial ornamental plant. Plant morphometry and sequences of three plastid DNA regions (rbcL, matK, trnH-psbA) were used to assess the phenotypic and genetic variability of this taxon and its closest congeneric species (in particular Pancratium linosae, from the volcanic island of Linosa) in the Central Mediterranean (Sicily, Tunisia and surrounding island…

Citizen and scientsts work together to monitor marine alien species in Sicilian waters (central Mediterranean)

2017

We report on the experience of two citizen science projects: the Project “Caulerpa cylindracea – Egadi Islands” and the Project “Invasive Algae”, included within the “Seawatchers” platform. The first one, sponsored by the STEBICEF Department of the University of Palermo and by the Egadi Islands Marine Protected Area (MPA), aims at creating a database on the spread dynamics of C. cylindracea within the Egadi Islands MPA. The second one, coordinated by the Institute of Marine Sciences of Barcelona (CSIC, Spain), collects data on 10 marine invasive alien species. The results of these projects highlighted the important role that citizen science campaigns can have as early-warning systems. We al…

Nuove tipologie di monumenti arborei in Sicilia

2009

Con riferimento ai monumenti arborei, gli autori propongono nuove tipologie che, oltre alla singola pianta, identificano gruppi, popolamenti e formazioni. Vengono riportati alcuni esempi di espressioni forestali monumentali, riconducibili alle sopraindicate tipologie riscontrate in Sicilia.

Cells of extramammary Paget's disease express cytokeratins different from those of epidermal cells.

1985

The patterns of expression of cytokeratin polypeptides which are closely correlated to routes of differentiation of epithelial cells were studied in extramammary Paget's disease. Cytokeratins of uninvolved and involved epidermis were analyzed by two-dimensional gel electrophoresis of microdissected tissue preparations as well as by immunofluorescence microscopy using cytokeratin antibodies with different specificities. In uninvolved epidermis, cytokeratins Nos. 1, 5, 6, 10, 11, 14, and 16, characteristic of keratinocytes, were found. Epidermis infiltrated by Paget's cells contained the same components and, in addition, cytokeratins Nos. 7, 8, 18, and 19, the latter being characteristic of s…

Zur Bewertung der Blattdornen vonHalimodendron halodendron (Fabaceae)

1979

Halimodendron halodendron is a spiny shrub of north-western Asia. The spines are formed by the rachises of the paripinnate leaves. After abscission of pinnae the rigid rachises remain for several years. In culture these rachis spines do not develop fully.

Mycoforestry in Sicily: a proposal to enhance the multifunctionality of forests

2017

Mycoforestry is forestry that aims to build on traditional rules to encourage forest ecosystem resilience while creating optimal conditions for fungal communities. Main goals of mycoforestry are: preservation of native forests, recovery and recycling of woodland debris, enhancement of replanted trees, strengthening sustainability of ecosystems, economic diversity. There is a large variety of fungi living in forests, each of which has a specific and complementary relationship to the diversity of native species, the ages of trees, the presence of dead trees or rich forest litter, etc. Fungi are the main responsible of wood decomposition and thus carbon and nutrient cycling, and they also form…
