I fattori di rischio per la biodiversità forestale in Sicilia: il caso studio del cerro di Gussone
2011
Il cerro di Gussone (Quercus Gussonei (Borzì) Brullo) è una specie endemica della Sicilia esclusiva della catena dei Nebrodi e del bosco della Ficuzza. Il presente studio ha esaminato la rinnovazione di questa pianta, nella Riserva Naturale Orientata “Bosco della Ficuzza, Rocca Busambra, Bosco del Cappelliere, Gorgo del Drago”. Si tratta di una formazione boschiva monoplana che mostra chiari segni di deperimento. Per isolare i fattori che influenzano la rinnovazione e la crescita delle giovani piantine è stato eseguito un piano di trattamenti. Il risultato dello studio ha confermato che la rinnovazione si afferma in parte e, soprattutto, le giovani piantine non si accrescono a causa della p…
A "laboratory" open air in the urban landscape of Palermo
2012
The study intends to make new contributions to knowledge of a interesting "laboratory" in the open air in the urban landscape of Palermo, a cultural and scientific heritage in which architecture, art and decoration coexist in an experiment of collective synergies. The Botanical Garden C enter, with its ten acres of land appears, still, a fervent creative process between artifice and nature, the expression of a specific historical and cultural climate in which expectations converged of a intellectual, scientific and institutional fervor. The academic institution, founded in 1789 with the intention of cultivating useful plants to the arts, crafts and medicine, contributed to the spread of tro…
Aggiornamento sulla nidificazione della Tartaruga marina Caretta caretta (Reptilia Cheloniidae) in Sicilia. Riflessioni sul valore della Citizen Scie…
2020
Updating of egg-laying of Loggerhead sea Turtle Caretta caretta (Reptilia Chelonidae) in Sicily. Remarks on the value of the Citizen Science. The aim of this paper is to put together data on the egg- laying by the Loggerhead sea Turtle Caretta caretta in Sicily, mainly after recordings by amateurs, tourists and occasional observers. 25 nesting events by this turtle are reported in the main island in 2017 and 2018. Comparing these figures with past records, they appear very high; it may be in part due to an awareness campaign carried out in the last years to solicit such reports. This suggests that Sicily may host a much higher nesting population of the Loggerhead sea Turtle than previously …
3D models acquisition and image processing for virtual musealization of the spezieria di Santa Maria della Scala, Rome
2022
This study was carried out within the project “Roma Hispana. Nuevas tecnologías aplicadas al estudio histórico, la musealización y la puesta en valor de Patrimonio Cultural español en Roma: la spezieria di Santa Maria della Scala” (Universitat de València Spain), which is funded by the Conselleria d’Innovació, Universitats, Ciència i Societat Digital of the Generalitat Valenciana (2020–2021) and authorized by the Sovrintendenza Speciale Archeologia Belle Arti e Paesaggio (Special Superintendence of Archeology, Fine Arts and Landscape) of Rome, Italy. The spezieria di Santa Maria della Scala was the oldest apothecary in…
Description and phylogenetic relationships of a new species of treefrog of theOsteocephalus buckleyispecies group (Anura: Hylidae)
2020
The Osteocephalus buckleyi species group is widely distributed in primary and secondary forests of the Amazon Basin and Guiana Region. Based on integrative analysis, including morphological and genetic data, we estimate the phylogenetic relationships and species boundaries among populations of the Osteocephalus buckleyi group from the Ecuadorian Amazon, focusing on the O. verruciger-O. cannatellai species complex. Our results uncovered the existence of one confirmed candidate species from Sangay National Park and one unconfirmed candidate species. Here, we describe the new species which is morphologically and ecologically distinct from other Osteocephalus species. The new species is unusual…
Taxonomic review of the
2017
Abstract Two new species of the genus Fulvius Stål are described from the Philippines and Papua New Guinea. A taxonomic review of representatives of the F.bifenestratus species group, illustrations of the male genitalia, a color habitus image of each species, and a key to species of the group are provided.
It takes time to see the menu from the body: an experiment on stable isotope composition in freshwater crayfishes
2015
For many applications and ecological studies in which wild individuals are brought to laboratory it would be essential to know accurately how fast novel diet is reflected in composition of different tissues. To study the effects of two different diets on the stable isotope composition of freshwater crayfish muscle and hemolymph, we conducted a three month experiment on noble crayfish (Astacus astacus) and signal crayfish (Pacifastacus leniusculus) by feeding them sweet corn (Zea mays) or Baltic herring (Clupea harengus membras) as novel food. During the experiment, the crayfish were given 0.4 g of selected food daily and the amount consumed was recorded. The samples for the stable isotope a…
Diet composition and seasonal feeding patterns of a freshwater ringed seal (Pusa hispida saimensis)
2015
The Saimaa ringed seal (Pusa hispida saimensis) is one of the few freshwater seal populations worldwide. The major conservation issue of this critically endangered population is bycatch mortality. We used digestive tract content and stable isotopes (d13C and d15N) to estimate the diet and seasonal feeding patterns for gaining better understanding of the seals feeding habits and potential conservation implications. The diet was similar across age groups. Altogether 15 fish species were identified and the most important were smelt (Osmerus eperlanus), ruff (Gymnocephalus cernuus), perch (Perca fluviatilis), vendace (Coregonus albula) and cyprinids. The high d15N values suggested that the seal…
Nomadtown, Manifesting the Global Village Hypothesis: A Case Study of a Rural Resilience Hub Within an Educational Milieu in North Karelia, Finland
2022
Artikkelissa esitellään NomadTown, joka on hätätilojen ennakointiin, torjuntaan ja sopeutumiseen sekä myönteisten vaikutusten tuottamiseen toimintansa perustava “resilienssihubi”. Artikkelissa hahmotellaan NomadTowniin kehittyneen alakulttuurin koulutuksellista taustaa ja tehdään syvällinen kuvaus NomadTownia ympäröivästä yhteiskunnasta oppimisen paikkana. Tämä kontekstuaalisointi nojaa tietoisuuteen dispositiivista Foucault'n tarkoittamassa mielessä. Tekstissä arvioidaan yhdistysten yhteiskuntaekologian, jonka puitteisiin tämä resilienssikeskus on asettumassa, soveltuvuutta ilmastonmuutoksen torjunnan edellyttämään suureen yhteiskunnalliseen transitioon. Lisäksi arvioidaan kuinka verkostom…
Dipinto su tavola “Tre Sante Martiri”: il restauro conservativo di un supporto ligneo gravemente danneggiato
2020
Il poster descrive l'intervento conservativo svolto su un dipinto su tavola raffigurante “Tre Sante Martiri”, secondo il consolidato principio di un approccio multidisciplinare tecnico e scientifico. Il manufatto, realizzato con la tecnica ad olio e risalente al XVII secolo, è di proprietà del Comune di Cefalù (PA), pervenuto a seguito di lascito testamentario da parte di un nobile collezionista dell’Ottocento, l’avvocato Vincenzo Cirincione, ed è conservato presso il locale Museo intitolato ad “Enrico Piraino barone di Mandralisca”. La prima parte dell’intervento ha riguardato lo studio degli aspetti storico-artistici, dei materiali e delle tecniche esecutive, degli interventi pregressi di…
