    Postfazione a: Alessandro Parronchi "Il Giuoco del Barone"

    No full text
    Il Giuoco del Barone è la riuscita opera prima del compositore Valentino Bucchi, su libretto di Alessandro Parronchi, ispirata all’omonimo gioco di società (una variante toscana del Gioco dell’Oca). L’opera da camera fu rappresentata per la prima volta a Firenze nel 1939 al Teatro “Sperimentale” di via Laura; nel corso del Novecento fu più volte messa in scena da registi quali Franco Zeffirelli, Cesare Orselli, Stefano Vizioli. Nel 1956, la trasposizione per radio vinse il Prix Italia, il concorso radiofonico internazionale più prestigioso. Il libretto di Alessandro Parronchi è ora riproposto in una raffinata versione curata dalle Edizioni San Marco dei Giustiniani in Genova. Un’edizione filologicamente curata da Marino Fuchs (sua anche la postfazione), arricchita dagli scritti di Valentino Bucchi, Alessandro Parronchi, del critico musicale Bruno Barilli e dalla tavola a colori del Giuoco del Barone, disegno originale di Guido Zibordi Marchesi

    Larval responses to turbulence and temperature in a tidal inlet: Habitat selection by dispersing gastropods?

The definitive version was published in Journal of Marine Research 68 (2010): 153-188, doi:10.1357/002224010793079013.Marine larval dispersal is affected by hydrodynamic transport and larval behavior, but little is known about how behavior affects large-scale patterns of dispersal and recruitment. Intertidal habitats are characterized by strong and variable turbulence relative to shelf and pelagic waters, so larval responses to turbulence may affect both dispersal and habitat selection. This study combined observations and theoretical approaches to model gastropod larval responses to multiple physical variables in a well-mixed tidal inlet. Physical measurements and larvae were collected in July 2004 in Barnstable Harbor, Massachusetts (USA). Physical measurements were incorporated in an advection-diffusion model where larval vertical velocity is a function of turbulence dissipation rate, temperature, and the temperature gradient. Modeled larval distributions were fitted to observed concentration profiles by maximum likelihood to estimate larval behavioral velocity (swimming or sinking) as a function of environmental conditions. These quantitative behavior estimates were used to test hypotheses about behavioral differences among groups and to assess the relative impact of different cues on overall larval behavior. Larvae of five common gastropod species from different coastal habitats reacted most strongly to turbulence but had genus-specific responses to environmental cues. Larvae of a species from tidal inlets (the mud snail Nassarius obsoletus) had near-zero velocities under calmer conditions and sank in strong turbulence. In contrast, larvae from exposed beach habitats (Crepidula spp. and Anachis spp.) sank in weak turbulence and swam up in strong turbulence, with additional responses to temperature and temperature gradient. Larval responses also differed between small and large size classes and between flood and ebb tides. Behavior of mud snail larvae would contribute to retention inside the inlet and near adult habitats, whereas behavior of beach snail larvae would contribute to rapid export from muddy inlets lacking suitable adult habitats.This work was funded by the Woods Hole Oceanographic Institution (WHOI) Coastal Ocean Institute, the WHOI Rinehart Coastal Research Center, the National Science Foundation (NSF OCE- 0326734), NSF and US Office of Naval Research grants to S.

    Mussel larval responses to turbulence are unaltered by larvalage or light condition

    Larval responses to hydromechanical cues potentially have important effects on larval dispersal and settlement. This study examined the behavior of mussel larvae (Mytilus edulis) in laboratory-generated turbulence representative of nearshore currents. We video recorded the behavior of early- and late-stage veligers in a grid-stirred tank at five turbulence levels under light and dark conditions. Water velocities and kinetic energy dissipation rates were measured using particle image velocimetry and acoustic Doppler velocimetry. We characterized the vertical velocity distributions for sinking, hovering, and swimming modes in still water and calculated the average larval behavioral velocity in turbulence. In still water, young larvae had more positive (upward) velocities than old larvae, and both stages had more positive velocities in light than in dark. In turbulence, the mean larval vertical velocity varied from positive at low dissipation rates to negative at dissipation rates above a threshold of 8.3 £ 1022 cm2 s23. At this threshold, the Kolmogorov length scale (h ¼ 590mm) was two to three times the mean larval shell lengths (171–256mm), implying that turbulence is detectable even by larvae that are smaller than the smallest eddies. Responses to turbulence were unaffected by larval age or light conditions and contributed substantial behavioral variation. By sinking in strong turbulence, mussel larvae could increase their flux to the bed in energetic coastal flows, particularly over rough substrates like mussel beds. The response to turbulence by early-stage larvae will also affect their dispersal and may help larvae remain near coastal populations.Peer reviewedOriginally published in Limnology and Oceanography: Fluids & Environments (2011) and available via this link: http://lofe.dukejournals.org/content/1/120.full.pdfCopyright 2011 by the Association for the Sciences of Limnology and Oceanography, Inc
