Cryptic cyanobacterial diversity in the giant cave (Trieste, Italy): the new genus Timaviella (Leptolyngbyaceae).
Full text linkThe microflora of hypogean environments has been studied increasingly
worldwide. However, some sites have hardly been examined or not studied at all; this is the
case for the Giant Cave, a Karst show cave located near Trieste, Italy. In the present study
we began characterizing the Giant Cave Lampenflora by using a polyphasic approach,
focusing, in particular, on three Leptolyngbya-like strains named GR2, GR4, and GR13. Light
and electron microscopic observations were carried out and the water-soluble pigment
composition was analysed. Phylogenetic reconstruction, based on the 16S rRNA gene and the
16S-23S ITS region, was performed to better understand the taxonomic position of these
strains, complemented by 16S-23S ITS secondary structure analysis. Ecological and
geographical data for the investigated strains and for the other cyanobacterial strains grouping
with them in the phylogenetic reconstructions were also considered. Based on the results,
strain GR2 was ascribed to the species Heteroleibleinia purpurascens (Hansgirg) Anagnostidis
& Komárek; strains GR4 and GR13 were attributed to a new genus of the family
Leptolyngbyaceae, Timaviella Sciuto & Moro, gen. nov., and represented two distinct species:
Timaviella circinata Sciuto & Moro and Timaviella karstica Sciuto & Moro

The hand, the stone and the mind: Exploring the agency of rocks in quarrying techniques
No full textThe accurate categorisation of the marks left on stone surfaces by the repetition of consistent gestures has become particularly meaningful in unveiling quarrying techniques. Traces of stone workings, left by the use of tools, constitute crucial information for recognising and interpreting the operational sequence (the chaîne opératoire) followed by quarrymen at quarry fronts, thus unveiling different scales of craftsmanship: from the specific process needed for detaching a single block to the general organisation of labour. Tool marks show how specialisation in extraction procedures may also be driven by the nature of the stone itself, and the agency of the rock should therefore be questioned when reconstructing the chaîne opératoire required for cutting stone blocks.
The interpretation of tool marks supports the reconstruction of the technical gestures carried out by quarrymen, as well as the conveyance of specific know-how within the workers’ community and the affordances of the stone itself (Gosden and Malafouris 2015). Broader theoretical thoughts on the cognitive development and transmission of techniques can be applied to the material evidence of different quarrying strategies, the construction of specific taskscapes and the crystallisation of assignments in the socio-cultural context. The examples herein are drawn from ethnographic case studies of a marble quarrying district near Carrara, in northeast Tuscany, Italy

La costruzione di connessioni longitudinali e trasversali sul waterfront centrale di Catania: applicazione del concetto di infrastruttura verde per la rigenerazione urbana
No full textIl processo di rigenerazione di un’area di interfaccia città-porto può affrontare il tema progettuale degli impatti dell'espansione incontrollata e della frammentazione urbana e dovrebbe, come mostrato da numerosi casi studio europei, potrebbe contribuire alla connettività nelle reti ecologiche e promuovere gli spazi verdi nell'ambiente urbano, laddove le infrastrutture portuali e di mobilità hanno interrotto la continuità ecologica del sistema costiero.
Aderendo alla strategia dell'UE per le infrastrutture verdi (Green Infrastructure Strategy), le infrastrutture verdi sono in grado di affrontare un'ampia gamma di sfide urbane, come la conservazione della biodiversità, l'adattamento ai cambiamenti climatici, il sostegno all'economia verde e il miglioramento della coesione sociale.
In particolare, il caso studio presentato nel contributo mira a dimostrare che l’approccio alla pianificazione di infrastrutture verdi nel contesto portuale e retroportuale della città di Catania è capace di:
• combinare la progettazione delle infrastrutture verdi e grigie;
• creare reti di spazi urbani verdi;
• supportare l'erogazione e il miglioramento di molteplici funzioni e servizi, integrati nelle funzioni urbane del waterfront.
Il contributo prende spunto dalla tesi di laurea magistrale in Pianificazione Territoriale Urbanistica e Ambientale discussa da Luciano Di Pietro e Giulia Sciuto con la relazione di Daniele Ronsivalle
Phlyctocythere sicula Sciuto & Pugliese 2013, n. sp.
No full textPhlyctocythere sicula n. sp. (Fig. 3) TYPE MATERIAL. — Holotype: Strait of Messina, central Mediterranean, R / V Universitatis, cruise MERC, Sampling station MERC 10 (38°07'14''N, 15°32'55"E; 545 m depth), terrigenous mud, 10.XII.2005, right valve (L 0.670 mm, H 0.365 mm), MNHN PMC. O8 H. 1.10.2012 (Fig. 3A). Paratypes: same data as holotype, 2 left valves, MNHN PMC.O 28P. 1.10.2012 (Fig. 3B), O 29P. 1.10.2012 (Fig. 3C). OTHER MATERIAL EXAMINED. — One left valve found in the Pleistocene (Calabrian) sedimentary succession cropping out at Scoppo (ME) (Fig. 1) along the sicilian side of the Strait of Messina. STRATIGRAPHIC RANGE.— Early Pleistocene (Calabrian) to Recent. ETIMOLOGY. — Named from the Sicily Island. DIAGNOSIS. — Phlyctocythere sicula n. sp. is characterised by a suboval, inflated carapace with swollen posteroventral area and a short caudal process in postero-central area. DESCRIPTION Carapace medium to large sized, suboval in lateral view.Anterior margin rounded and slightly pointed, dorsal margin regularly arched and convex, gently passing to the caudal process of the posterior area (Fig. 3A, B). Caudal process short and obtuse. Ventral margin slightly sinuous, regularly and steeply bending to the posterior margin towards the caudal process. Carapace inflated and oval in dorsal view. Outer surface lightly ornamented by a very weak reticulum particularly evident in the ventrolateral area (Fig. 3I). Few normal pore-canals, simple and evenly distributed, widely spaced, on the surface of the valve (Fig. 3C, G, H). Inner lamella anteriorly wide, narrower posteriorly, reduced to the minimum ventrally (Fig. 3C). Vestibula large anteriorly, narrow in postero-ventral area (Fig. 3C). Marginal pore-canals not observable. Eye tubercles absent. Hinge merodont: in the LV a curved smooth bar (Fig. 3C, F) with two little elongated lateral grooves at the anterior and posterior ends (Fig. 3G, H). RV with complementary elements. Four adductor scars and a single dorsal muscle scar (Fig. 3 C, D). REMARKS Phlyctocythere sicula n. sp. shows general features, and particularly the outline, similar to those of Loxoconcha Sars, 1866 and, especially, to Loxoconchella Triebel, 1954, but differs from both of them mainly because of the weak ornamentation of the carapace. Relatively to the hinge, the genus Phlyctocythere seems to show a wide variability; despite, Keij (1958) described the hinge of the type species as adont in its original description. Several species assigned to Phlyctocythere actually have a more or less developed hinge. P. pellucida (Müller, 1894) possesses a hinge as do some specimens, recorded by Van Morkoven (1963) and left in open nomenclature, which show traces of hinge terminal elements. Similarly, P. curva Van den Bold, 1988 shows a hinge "Weak, in the left valve consisting of a long, curved, very slightly crenulate bar with terminal, elongate, slightly, crenulate sockets" (Van den Bold 1988: 52). Consequently, the presence of a merodont hinge in the observed species does not prevent its inclusion within the genus Phlyctocythere. Furthermore, the present species has been assigned to Anchistrocheles using some features belonging to the type species such as the four muscle scars in row, the different vestibula, the normal pore canals widely spaced and the light ornamentation of the outer surface of the carapace. Phlyctocythere includes 12 living species and some fossil ones; some of them are reported in open nomenclature. It has a present-day and fossil worldwide distribution. The oldest species have been doubtfully reported from the Barremian of SE France (Donze 1971), and further taxa are known from the Eocene of the Paris Basin (Keij 1958), the Tortonian-Messinian of SE Sicily (Ciampo 1980) and the Pleistocene of Italy (Ciampo 1976; Moncharmont-Zei et al. 1985). Living species have been reported from the Mediterranean (Müller 1894; Ciampo 2003), the south Pacific (Correge 1993), the NE Atlantic (Freiwald & Mostafawi 1998), northwestern Europe (Sars 1866; 1922 -1928), North Carolina (Atlantic Ocean) (Hazel 1975), tropical West Africa (Hartmann & Hartmann Schroeder 1975). In the Recent Mediterranean the genus Phlyctocythere was formerly known only with P. pellucida (Müller, 1894). Phlyctocythere pellucida was reported from: 1) the Gulf of Naples associated with calcareuos algae down to a depth of 100 m (Puri et al. 1964); 2) Malta, where it was collected from 9 and 128 m (Bonaduce & Masoli 1970); 3) the east Mediterranean (Liban), collected from 75 and 245 m (Bonaduce et al. 1970); 4) Adriatic Sea down to 150 m (Uffenorde 1972; Bonaduce et al. 1975). Phlyctocythere sicula n. sp. is distinguishable from P. pellucida because of the more rounded outline, the caudal process less marked, more obtuse and more shifted to the median side of the posterior end; the postero-ventral area inflated, the more acute anterior margin, the narrower marginal zone and vestibula.Published as part of Sciuto, Francesco & Pugliese, Nevio, 2013, Description of two new species of ostracods from the Strait of Messina (central Mediterranean), pp. 35-44 in Zoosystema 35 (1) on pages 40-42, DOI: 10.5252/z2013n1a4, http://zenodo.org/record/453913
