Linosa: quando la geologia decide il destino di un’isola.
2015
La condizione odierna della flora ma anche dell'agricoltura di Linosa è molto diversa da quella della vicina Lampedusa per ragioni geologiche, il suolo vulcanico di Linosa ha influito sui caratteri della vegetazione dlel'Isola.
LA DIRETTIVA 92/43/CEE ED IL PATRIMONIO AGRO-FORESTALE, PRE-FORESTALE E FORESTALE SICILIANO: ALCUNE NOTE CRITICHE
2009
The 92/43/EEC Directive and the Sicilian agro-forest, pre-forest and forest heritage: some critical remarks – In order to redact the management criteria for the agro-forest and the autochthonous pre-forest and forest heritage within the Sicilian CSI Management Plans, during 2008 a critique analysis of the Interpretation Manual of European Union Habitats “Eur27” has been carried out. This manual treats quite adequately the mesophilous coenoses, the sclerophyllous forests and the conifer ones; on the other hand, some discrepancies need to be pointed out: for instance, some habitats quoted for Sicily (e.g. “matorral with Juniperus phoenicea” and “with Zizyphus lotus”) actually correspond to ve…

Classificare i paesaggi culturali tradizionali: criteri metodologici e applicazione
2009
The Italian peninsula is characterized by a high presence of Traditional Landscapes. “Traditional” refers to those landscapes that have a long history, a slow change, in agreement with the environmental factors. However, this high landscape richness is not supported by widespread inventory tools. A multidisciplinary approach is necessary in landscape analysis. Differences come out comparing the few existing inventories at national and sub-national levels in Italy based on holistic criteria, due to the number and type of thematic layers used in the analysis. Moreover, more sectorial approaches exist in the agronomic anf forestry field, often analysing and detecting landscape agro-forestry un…
Inventario e monitoraggio delle risorse forestali del sito Natura 2000 “Bosco di S. Adriano”
2008
The WP5 (Action 5.4) of the ManagMED project foresees measurement, evaluation, and estimation of the parameters that have a negative impact on the sites, throughout the use of innovative inventory methods (A5.4). The preliminary studies (WP2) carried out on the chosen Nature 2000 sites, contributed in recognising phenomena and activities which have a negative impact on the protection state of the sites. Mapping, inventories, and forest monitoring constitute the support base allowing acknowledging of environments, and of conservation and evaluation methods of the natural resources, therefore permitting planning of ideal methods for the realisation of a non- passive integration between man an…
Il Tetrops starkii chevrolat, 1859 in Sicilia (Coleoptera Cerambycidae)
2009
First report of Cerambicide Tetrops starkii Chevrolat, 1859 (Coleoptera Cerambycidae) in Sicily. Is reported the presence in Sicily of the new Beetle Cerambycidae Tetrops starki Chevrolat, 1859 found on Fraxinus angustifolia larval stage and carried out some observations of biological and forestry on the host plants.
1200-yr high-resolution terrestrial climate archive from the middle of the Mediterranean: The sedimentary record from Lake “Specchio di Venere” on Pa…
2011
The special location of Lake "Specchio di Venere" on Pantelleria Island in the Sicily Channel (Mediterranean Sea) between Tunisia and Sicily offers a unique terrestrial archive recording atmospheric changes, which are otherwise difficult to decipher in the marine records from this area. The lake is an endorheic saline basin with a maximum depth of 12.5 m. As the water input depends on rainfall, precipitation variations influence changes of the lake's water chemistry. In summer 2008, Lake Venere was cored with a modified Livingstone corer revealing a composite sedimentary sequence of 10.29 m length. Two radiocarbon dates form a preliminary age model indicating a very high sedimentation rate …
PLUMBAGO AURICULATA LAM. (Plumbaginaceae) IN SICILIA OCCIDENTALE: NUOVI DATI SULLA SUA DIFFUSIONE COME ESOTICA CASUALE
2017
Plumbago auriculata Lam. (Plumbaginaceae) in western Sicily: new data on its spread as casual alien. In questa nota si fornisce un quadro aggiornato sui casi di naturalizzazione di Plumbago auriculata Lam. (Plumbaginaceae) nella Sicilia occidentale e sul suo status invasivo a livello nazionale ed internazionale. Questa xenofita viene segnalata per la prima volta in diverse aree delle province di Agrigento, Palermo e Trapani, dopo essere stata segnalata per la prima volta presso l'isola di Linosa, nell'arcipelago delle Pelagie.
The ancient irrigation system of the Palermo Plain (Sicily, Italy) as a substitute ecosystem: preliminary investigations on its aquatic flora
2022
Many cities around the world are expanding, including in their perimeters green and blues spaces that could be crucial for the maintaining of biodiversity. Urban waterbodies are generally created to provide other services, but correctly managed they can provide also relevant ecosystem services. The Palermo Plain was characterized, in the past centuries, by several wetlands that were progressively destroyed (or “reclaimed”). The ancient irrigation system, probably set during the Arab domination (IX-XI century A.D.), became a substitute ecosystem able to host a significant biodiversity. Our research focused on the remains of this system, scattered in the relictual green areas of the Plain, an…
SIMBIONTI RADICALI DI ASTRAGALUS NEBRODENSIS (GUSS.) STROBL.
2013
Le leguminose spontanee mediterranee hanno un elevato potenziale nei processi di rinaturalizzazione di ecosistemi degradati o semiaridi poiché stabiliscono simbiosi radicali con batteri azoto-fissatori e funghi micorrizici i quali, agendo sinergicamente, avvantaggiano la pianta per la nutrizione e la resistenza agli stress. Astragalus nebrodensis è un arbusto perenne appartenente alla famiglia delle Fabaceae, endemico in Sicilia; i simbionti radicali di questa specie non sono noti. Gli obiettivi di questo studio sono stati: 1) l’analisi della diversità dei rizobi simbionti di Astragalus nebrodensis; 2) la valutazione dell’effetto dell’inoculo di rizobi da collezione e di funghi micorrizici …
