Stable carbon and nitrogen ratios in the sand smelt from a Mediterranean coastal area: Feeding habits and effect of season and size

2002

Enriched (δ13C values (annual average - 11·2%) suggest that in the study site (Stagnone di Marsala, Italy) the sand smelt Atherina boyeri exploited benthic prey throughout the year. In particular, Mysidacea and Isopoda seemed to dominate the diet. Stomach content data from the literature was in partial agreement with the present isotopic analysis suggesting that, while Mysidacea and Isopoda are exploited by A. boyeri, Copepoda Harpacticoida and Amphipoda are the dominant food items of the sand smelt diet. Several hypotheses are proposed to explain such partially different results from the two techniques. Both season and size influenced the δ13C and δ15N values of A. boyeri. Although through…

Crostacei Anfipodi associati ai reef di Sabellaria alveolata (Annelida: Sabellariidae) del Canale di Sicilia (Mar Mediterraneo)

2015

We describe diversity and patterns of spatial distribution of the amphipod fauna associated with reefs of the polychaete Sabellaria alveolata (L.) in the Sicily Strait. Samples were collected in June 2013, at three localities. Amphipod assemblages appeared homogeneous in the study area with variability increasing with decreasing spatial scale of observation. Jassa ocia (Bate) and Gammaropsis ulrici Krapp-Schickel & Myers characterized the studied assemblages.

Do invasive macroalgae influence biodiversity and abundance of Amphipod Crustaceans ?

2013

Amphipods are an essential element of the food web in marine coastal environments, and represent a good indicator of the health of the ecosystems. The composition of amphipod assemblage is often linked to algal coverage, in which the benthic species find refuge from predators and a great availability of food resources. Within the management and conservation of natural environments, one of the main problems is currently represented by the invasion of non-indigenous species, which modifies native communities. This research compares the amphipod fauna associated with Asparagopsis taxiformis (Delile) Trevisan de Saint-Léon, a non-indigenous red macroalga widely distributed along the west coast …

Dissolution of nitrones in alkylphosphates: A structural study

2022

Nitrones are chemical compounds with well-established anti-oxidant and spin-trapping properties. Their low solubility in water for many of them limits their applications, so opportune solvents must be found. In this study, two recently synthetized oxindole nitrones with proven antiproliferative and antioxidant activity have been dissolved in several liquid amphiphiles, chosen as model solvents. The effect of the polar head nature and the alkyl chain length/type have been investigated by a combined experimental (solubility, UV–vis spectroscopy) / computational (molecular dynamics) approach. The different chemical structures of the various solvents offer different chemical environments to the…

Noterelle al «Filostrato» e al «Ninfale fiesolano» di Giovanni Boccaccio

2022

Abstract: This paper presents three brief reading notes on as many passages of the Filostrato (IV 51:1-8; IV 56, 4-8) and the Ninfale fiesolano (229, 1-5) by Giovanni Boccaccio, in the search for probable classical and medieval latin sources and models that have so far escaped the attention of scholars.

Suggestioni favolistiche, espressioni sentenziose e tonalità moraleggianti nel «Pamphilus»

2022

Le commedie elegiache latine del XII e XIII secolo sono spesso caratterizzate da echi e suggestioni di origine favolistica, nonché da forti componenti di stampo moralistico, esemplare, proverbiale. In tal dire-zione, una delle più significative è senz’altro il «Pamphilus», composto all’inizio del XII secolo e ampiamente debitore, quanto alla trama, alle tematiche e ai personaggi, nei confronti del «De nuntio sagaci». In questo saggio, attraverso un’approfondita lettura della commedia, si insiste sulle suggestioni favolistiche, sulle espressioni proverbiali e sulle tonalità moraleggianti che largamente la innervano, fino a costituirne un elemento assolutamente indispensabile, già, d’altra pa…

Effetti scenici nel «Pamphilus» e nel «Babio»

2009

Fra le “commedie elegiache” latine del XII e XIII secolo, il «Pamphilus» e il «Babio» rappresentano al meglio le componenti spiccatamente “teatrali” del genere comico-elegiaco mediolatino. Infatti, oltre a essere interamente dialogate – mentre tutte le altre “commedie elegiache” sono miste di parti dialogate e di parti narrative – il «Pamphilus» e il «Babio» presentano entrambe una lunga serie di elementi scenici (didascalie interne, battute a sorpresa, dialoghi rapidi a botta e risposta, e così via) che possono far presupporre un’intenzione rappresentativa da parte degli autori o, comunque, risultano finalizzati a una possibile resa scenica. Per entrambe le “commedie”, dopo una sintetica p…
