Size-dependent predation of the mesopredator Marthasterias glacialis (L.) (Asteroidea)
2016
Asteroids are largely recognized as important predators in all of the world’s oceans and for this reason, they play a crucial role in shaping the structure and functioning of benthic ecosystems. The spiny starfish Marthasterias glacialis is generally considered a voracious predator of molluscs, in particular bivalves. Using field observations and carbon (δ13C) and nitrogen (δ15N) stable isotopes, we explored possible changes in diet in relation to size of M. glacialis. Data were collected at Ustica Island (Southern Tyrrhenian Sea) from June 2008 to June 2010. M. glacialis showed a size shift in feeding preferences due to different use of food items: bivalves, Columbella rustica, Euthria cor…
Factors affecting population dynamics of Eurasian woodcocks wintering in France: assessing the efficiency of a hunting-free reserve
2005
International audience; The Eurasian woodcock Scolopax rusticola is a migratory bird of major importance for hunting, which is susceptible to habitat loss and the stochastic effects of severe winter weather. Conservation issues mostly concerned regulation of hunting, but the efficiency of hunting-free reserves has never been investigated. We studied causes of mortality and survival probabilities of 98 radio-tagged woodcocks in a reserve with no hunting and in an adjoining hunting area in Brittany (France). Predation, mostly by mammalian predators on fields at night, was similar among adults and yearlings, while hunting mortality was more important in yearlings. Overall winter survival proba…
Morphological and molecular tools in identifying the Mediterranean limpets Patella caerulea, Patella aspera and Patella rustica
2003
Allozyme electrophoresis, a partial nucleotide sequence of a mitochondrial gene for cytochrome oxidase I (COI) and discriminant analysis of shell morphometric characters were used to study the relationships among the Sicilian marine gastropods of the Patella genus. Allozyme and mtDNA markers unequivocally distinguished the species and were very useful markers in correctly classifying the different species when morphological characters overlapped each other. Several allozyme loci and many nucleotide positions were diagnostic of species. In contrast, the discriminant analysis of simple morphometric shell characters failed to adequately discriminate the species, suggesting that environmental f…
Pistachio fruits rust caused by Tuberculina persicina (Ditmar) Sacc., anamorph of Helicobasidium purpureum (Tul.) Pat.
2020
In the study, we found rust in pistachio fruits and verified that it was caused by Tuberculina persicina, anamorph of Helicobasidium purpureum, through isolation and culture, microscopic observation, molecular identification and pathogenicity tests of Koch’s postulates. To our knowledge, this is the first report of rust fruit in pistachio caused by Tuberculina persicina.
The antioxidant power of horseradish, Armoracia rusticana, underlies antimicrobial and antiradical effects, exerted in vitro
2018
Armoracia rusticana (AR) was tested for antimicrobial and antioxidants power. The compound demonstrated to inhibit fish pathogens such as Vibrio anguillarum, V. harvey, V. alginolyticus, Aeromonas hydrophila, A. salmonicida, Photobacterium damselae subspecie piscicida, Tenacibaculum marinum and Pseudomonas anguilliseptica,. The total phenolic content and the reducing power resulted higher in the water extract of AR, respect to the hydroalcoolic. In vitro test demonstrated that AR significantly protect cells against death, induced by oxidative stress.

Parte III, Capitolo III, Fondo e azienda agricola
2021
Questo volume nasce dalla necessità di offrire una lettura aggiornata, contemporanea appunto, delle peculiari regole che tradizionalmente han- no attribuito al Diritto agrario un carattere di specialità. Facciamo riferimento alle norme che in un’ottica di programmazione di un settore produttivo peculiare disciplinano l’impresa agricola, la proprietà terriera, i contratti agrari, il lavoro agricolo, il credito agrario, il mercato dei prodotti agricoli. Regole la cui chiave di lettura è sempre passata dalla considerazione dell’esistenza di un legame stretto tra “agricoltura” e “terra”, considerazione che non riteniamo superata, ma piuttosto aggiornata, dalle numerose innovazioni legislati…
Fotografie dell'Italia: Verga e Mascagni
2018
Il testo è articolato in forma di cronologia e ricostruisce i percorsi biografici e artistici di Giovanni Verga e Pietro Mascagni, con particolare riferimento alla genesi di "Cavalleria rusticana" (1890) e alle controversie legali seguite alla rappresentazione dell'opera.
Un'ipotesi sull'origine del non usus
2012
The author reproposes a conjecture of Giuseppe Grosso about the origin of the iura praediorum rusticorum’s loss by non-use and tries to show its ground in the sources. According to such a view the oldest rustic servitudes (iter, actus, via, aquae ductus) ended in ancient roman law, if the owner of the dominant estate abstained from exercising them for two years, by an usucapio in favour of the servient owner. Only when these rights – originally conceived as property’s forms – were regarded as iura in re aliena their non-use became an autonomous method of extinction and was extended to the other rustic servitudes and to the usufruct.
