Nell’ambito delle indagini svolte sul rischio desertificazione nei 390
comuni della Regione Siciliana, sono emersi dei limiti nell’adozione
tout court del protocollo MEDALUS.
Gli AA. hanno quindi avviato una rivisitazione critica degli strati tematici
da adottare per una nuova cartografia a scala 1:250.000 propedeutica alla stesura delle linee guid...
La desertificazione, oltre ai processi naturali ed agli effetti dei cambiamenti climatici, è direttamente correlata all’abbandono della terra. Dal 1936 al 1950, periodo a cavallo della guerra, nell’80% dei comuni siciliani la popolazione è cresciuta, ma dal ’51 al ’71, nell’80% dei casi la popolazione ha subito una decrescita a beneficio delle aree...
The results of a long investigation (20 years) on bryophyte diversity of 28 Sicilian caves are reported; the study regarded both karstic and volcanic caves, located at altitudes ranging from 15 to 2030 m a.s.l. The bryophyte diversity consists of a total of 136 taxa, 20 liverworts, 3 hornworts and 113 mosses. The ecological analysis was performed u...
Francesco Cupani, a pre-Linnaean Sicilian botanist, would have liked to produce a volume of “Natural History” of Sicily. Since 1692 he had been preparing the drawings and the engravings that were destined to constitute the illustrations of Panphyton Siculum. This particularly ambitious work was not completed partly because of the author’s premature...
The results of a study on pollen morphology of the species of the genus Ptilostemon growing in Italy: Ptilostemon niveus, P. greuteri, P. gnaphaloides, P. casabonae, P. strictus, P. stellatus by light and scanning electron microscopy were presented and discussed including in relation to their taxonomic position. The exine shows two different orname...
Pulvirenti S., M. M. Indriolo, P. Pavone & R. M. S. Costa (2015). Study of a pre-Linnaean Herbarium attributed to Francesco Cupani (1657–1710). Candollea 70: 67–99. In English, English abstract. The aim of this work is the study of one of the two pre-Linnaean herbaria belonging to the University of Catania, attributed to Francesco Cupani, a 17th ce...
Francesco Cupani, a seventeenth century Sicilian botanist, developed a network of scientific exchanges and connections with the most important scientists of his time. Despite living in considerable isolation, he managed, above all thanks to Sherard, to correspond and exchange with Ray, Commelin, Tournefort, Triumfetti, Volkamer and Böhm. He partici...
Gargano is one of the richest Mediterranean areas in biodiversity. The work reports an assessment of the presence and conservation status of the habitats according to the 92/43/EEC Directive of Gargano coastal and low hill belts, their relationships with plant communities, threatened species, phytoclimatology, threats, and suggestions for managemen...
Map of the habitat of the EEC Directive 92/43 in the biotopes of the Syracuse province (eastern Sicily). In the framework of activities to the creation of the provincial landscaping plan of Syracuse, a map of the habitats (scale 1:10.00) of the EEC Directive 92/43 is presented. The habitat mapping, realized in a GIS environment, allowed the impleme...
In the framework of the activities aimed to the creation of the provincial landscaping plan of Syracuse, a map of the habitats (scale 1:10.000) of the EEC Directive 92/43 is presented. The habitat mapping, realized in a GIS environment, allowed the implementation of a geo-referred database within a territorial informative system and the production...
