Feste tradizionali, identità locali e mercato culturale in Sicilia

2010

In Sicilia, così come in altre aree del Meridione d’Italia, può essere tutt’oggi osservata una diffusa persistenza di forme di cerimonialità religiosa tradizionale, solo in certi casi interessate da processi di adeguamento a standards di fruizione –avvertiti come prioritari segnatamente a livello istituzionale-, “interessanti” per il mercato turistico. Non si registra, di contro, nell’Isola, se non episodicamente e limitatamente ai centri maggiori, la prepotente emergenza di fenomeni di riscoperta e reinvenzione di pratiche festive che caratterizza piuttosto le regioni centro-settentrionali d’Italia. Questa realtà “altra” necessita di essere studiata, partecipata, compresa e comunicata a ch…

LE VERGINI DEL MIRTO. EPIFANIE MARIANE E ALBERI SACRI TRA LA SICILIA E CRETA

2021

I simbolismi vegetali sono ricorrenti nelle celebrazioni religiose “popolari” di santi/e, madonne, Cristi sotto vario titolo in tutta l’area euro-mediterranea, segnatamente in quelle regioni che sono state caratterizzate fino a un recente passato (e che in parte lo restano tutt’oggi) da un’economia prettamente agropastorale. Interi alberi, fronde, frutti, spighe compaiono in numerosi casi, isolati o in associazione fra loro e con altri simboli rituali propri dei patterns simbolici agrari  (pani, pasti comuni, falò e cortei di torce, danze, corse, agoni, ecc.), sia come decoro di spazi e di immagini cultuali, sia assemblati in più o meno complessi artefatti (che non di rado costituiscono il …

Musica, architettura e arti figurative nella Palermo di Giacomo Amato

2017

Il contributo ripercorre le occasioni d'incontro tra la musica, l'architettura e le arti figurative negli anni in cui l'architetto Giacomo Amato fu attivo a Palermo, dal ritorno da Roma nel 1684 al 1732, data della sua morte. Si discute l'attività di Amato in due specifici campi connessi alla musica: da una parte scenografie e costumi per rappresentazioni legate alla committenza vicereale; dall'altra apparati per celebrazioni religiose non liturgiche quali le Quarant'ore o il Corpus Domini. Il suo apporto viene considerato in raffronto con la produzione simile di altri centri italiani, nel quadro della vita musicale dell'epoca.

Aggregation ofArgulus coregoni(Crustacea: Branchiura) on rainbow trout (Oncorhynchus mykiss): a consequence of host susceptibility or exposure?

2005

By sampling individual rainbow trout,Oncorhynchus mykiss, at a fish farm we showed thatArgulus coregoniwere aggregated within their host population. The relative significance of susceptibility and exposure generating the observed pattern was tested using experimental infections. We examined, whether rainbow trout developed protective resistance mechanisms against the louse following a challenge infection and if there was variation between individual trout in their susceptibility toA. coregonimetanauplii. Fish were exposed to 20A. coregonifor 5, 25, 50, 85 or 120 min and the numbers attaching recorded. Three weeks later, developing argulids were removed and the experiment repeated with a sta…

Seasonal dynamics of egg laying and egg-laying strategy of the ectoparasite Argulus coregoni (Crustacea: Branchiura).

2004

Substrate preferences, spatial aggregation patterns and seasonal dynamics in the egg laying of ectoparasiticArgulus coregoniwere studied at a commercial fish farm in Finland. Pilot experiments showed thatA. coregonifemales selected specific types of substrates for egg laying. Significantly moreA. coregonieggs were laid on dark substrates than on light ones suggesting the use of visual cues. Therefore, egg-laying plates of dark colour were constructed for further experiments. MostA. coregonieggs were deposited in locations in shadow and in the deepest water in a 2 m deep farming canal. Relatively more eggs were laid on bottom stones situated near each egg-laying trap than on artificial egg-l…

ORAL MANIFESTATIONS IN GASTROESOPHAGEAL REFLUX DISEASE

2005

The gastroesophageal reflux (passage of gastric contents into the oesophagus and the mouth) is the main sign/symptom of a very frequent gastroesophageal reflux disease. Thus, acid regurgitation originates from stomach and it is responsible of the onset of tipical symptoms and mucosal injury. Also in oral cavity the noxious acid agent is able to injure oral cavity (soft and hard tissues). These involvementes are described from international literature, even if a greater interest has shown to date only for hard tissue injury.

Seasonal studies of the biology ofAchtheres percarumin perch,Perca fluviatilis, from four Finnish lakes over a 3-year period

1993

Achtheres percarum infection on the gills of perch Perca fluviatilis was studied from four lakes in central Finland in monthly or bimonthly samples of fish during a 3-year period. The highest prevalence and intensity of infection (30%, 0.7 copepods/fish) were found in the oligotrophic, unpolluted Lake Peurunka and the lowest (6%, 0.1 copepods/fish) in the eutrophic and polluted Lake Vatia. According to hierarchical loglinear models the prevalence of A. percarum infection was related to the lake, but not to the year. However, when logit models were constructed such that two ‘seasons’ (‘cold’ and ‘warm’ periods) were included, it was apparent that the year also influenced the prevalence of A.…

Climate warming and disease risks in temperate regions – Argulus coregoni and Diplostomum spathaceum as case studies

2006

AbstractThe link between climate changes and disease risks from various pathogens has been increasingly recognized. The effect of climatic factors on host–parasite population dynamics is particularly evident in northern latitudes where the occurrence and transmission of parasites are strongly regulated by seasonality-driven changes in environmental temperatures. Shortened winter periods would increase growth potential of many parasite populations. The ways in which climate warming could affect life history dynamics of the directly transmitted crustacean ectoparasite Argulus coregoni and complex life cycle trematode Diplostomum spathaceum, which frequently cause problems in northern fish far…

Embryonic development in corkwing wrasse, Symphodus melops

2019

Corkwing wrasse, Symphodus melops, is one of the main species used as cleaner fish to combat sea lice infestation in salmon aquaculture; however, there is little knowledge about its biology. Here, we describe the embryonic development of this species and examine the viability of the eggs under three temperature regimes. The experiments were conducted at three water temperature regimes, 12, 15, and 18°C, which resemble common sea water temperatures registered during the spawning season of corkwing wrasse at different latitudes along the Norwegian coast. Corkwing wrasse spawn small spherical eggs of 0.75–0.80 mm in diameter (mean 0.78, CV = 3.6%) with several oil droplets and go through eight…
