Three new species of Raphitoma Bellardi, 1847 (Mollusca, Gastropoda, Raphitomidae) from Croatian waters (NE Adriatic Sea)
No full textThree new species of the neogastropod family Raphitomidae Bellardi, 1875, are described from the Croatian waters of the Adriatic Sea: Raphitoma petanii Prkić, Giannuzzi-Savelli & Pusateri n. sp., R. pusaterii Prkić & Giannuzzi-Savelli n. sp. and R. stanici Prkić, Giannuzzi-Savelli & Pusateri n. sp. The new species are diagnosed by teleoconch characters and by genetic data (COI sequences) in an integrative taxonomy framework. They belong to a group of species with microgranules on the external surface of all teleoconch whorls and all three have a multispiral protoconch indicating a planktotrophic larval phase. The first two species are so far known only from material found in Croatia. R. petanii Prkić, Giannuzzi-Savelli & Pusateri n. sp. and R. stanici Prkić, Giannuzzi-Savelli & Pusateri n. sp. are predominantly shallow-water species, whereas R. pusaterii Prkić & Giannuzzi-Savelli n. sp. has been so far collected only from deeper bottoms with presence of the red coral, Corallium rubrum (Linnaeus, 1758). Syntypes of Murex echinatusBrocchi, 1814 are figured and commented
Mineral chemistry of the calcalkaline lavas from Marsili Seamount (southeast Tyrrhenian Sea): some magmatological and geodynamic considerations
No full textMineral chemistry data from lavas recovered over a large depth interval of the deep-water volcano of Marsili (Aeolian back-arc, SE Tyrrhenian Sea) are presented. The volcano is built up by products of calcalkaline affinity with the only exception of one outcrop of sub-alkaline, within plate basalts in the crestal area. On the whole, the calcalkaline lavas of Marsili have bimodal composition, and consist of basalts and andesites with, respectively, calcalkaline and high-K serial affinity. The andesites mark a change in the geodynamic conditions that is reflected by the clockwise rotation of the seamount rifting from the early NNE-SSE orientation, associated with the extrusion of the basalts, to a dominant tensional regime trending almost NE-SW. This evolution is discussed in the context of some magmatic-structural features in the southest Tyrrhenian volcanic area. -from Author
Revision of Mediterranean and NE Atlantic Raphitomidae (Gastropoda, Conoidea) 8: The genus Leufroyia Monterosato, 1884
No full textThe four recent species of the genus Leufroyia Monterosato, 1884 are revised based on an integrative taxonomy approach: L. leufroyi (Michaud, 1828), L. concinna (Scacchi, 1836), L. erronea Monterosato, 1884 and L. villaria (Pusateri & Giannuzzi-Savelli, 2008)
La regione turistica adriatica: strategie imprenditoriali e immagini del territorio
No full textLa relazione presenta alcuni risultati della ricerca Prin 2003 su "Reti imprenditoriali e politiche locali nelle aree turistico-balneari dell'Emilia-Romagna", diretta dall'autore nel quadro della ricerca nazionale dal titolo "Sistemi turistici locali: reti territoriali e politiche pubbliche, coordinato da G. Martinotti, dell'Università di Milano-Bicocca.
Sommario: localismo, specificità e globalizzazione nel turismo; immagini e significati della linea di costa; il territorio turistico nelle linee d'azione imprenditoriale (resistere nel turismo di massa; razionalizzare il territorio; recuperare l'identità locale; competere attraverso la differenziazione; accentuare il protagonismo locale; sviluppare un'offerta multidimansionale); conclusioni
