Redescription of Licnophora chattoni Villeneuve-Brachon, 1939 (Ciliophora, Spirotrichea), associated with Zyzzyzus warreni Calder, 1988 (Cnidaria, Hydrozoa)

Licnophora chattoni, found in association with Zyzzyzus warreni, a tubulariid hydroid epizoic in sponges from Sao Sebastiao (SP, Brazil), is redescribed and illustrated using light and electron microscopy. The ciliate has a flexible, transparent body formed by an oval anterior region linked to the posterior basal disc via a flexible neck region. Numerous cortical granules are observed scattered throughout the body and densely packed along the neck. The adoral zone is formed by about 81 external and 24 infundibular paramembranelles. The paroral membrane, formed by a row of long cilia arranged in monolcinetids, extends through a groove in the body to the adhesive disc. Two dorsal kinetids are present along the right body margin and around the neck. The adhesive disc (18 mu m in diameter) lacks cilia in the area above the velum. The velum covers a row of dikinetids bearing long cilia and four dikineties, two or three of which are interrupted on the ventral surface. Nine to twelve macronuclear nodules connected by isthmuses are distributed in the cytoplasm, plus two nodules located in the adhesive disc and between those there is an ovate micronucleus.

New species of Fissiphallius Martens 1988 from Brazil and notes on the morphology of Fissiphalliidae (Arachnida, Opiliones)

The seventh species of Fissiphallidae, Fissiphallius orube sp. nov., and the fourth from Brazil (type locality state of Acre, Cruzeiro do Sul, at the Moa river), is described. The new species differs from the remaining species of the family in lacking a pergula, having a knob at the base of the rutrum, and the ocularium spiniform projection with apical portion single or divided in two to three parts.

Neogene and Pleistocene fossil brachiopods of the Eastern Islands. Current appointments.

[EN] Numerous specimens of fossil brachiopods have been found in the different fossiliferous outcrops of the Canary Islands. These fossils have been found in the deposits of Mio-Pliocene age of the eastern Canary Islands, described and illustrated in the work of Meco et ali. 2005 and in the outcrops interpreted as a tsunami deposits  in Piedra Alta, Lanzarote, belonging to the Marine Isotope Stage 11 dated to circa 330 ka. 4 species of fossil brachiopods have been identificated: Terebratula sinuous Brocchi 1814, Lacazella mediterranea Risso 1826 Terebratulina caputserpentis (Zbyszewski, 1957) and Thecidium cf . digitatum (Sowerby 1823). These fossils provides stratigraphic and paleoclimatic taxonomic information. Furthermore, in order to compare the fossil brachiopods with present in the Canary Island, a reference collection is defined with specimens obtained from marine sediment surveys at Gran Canaria, La Palma and El Hierro, identifying 3 species: Argyrotheca barrettiatia (Davidson, 1866), Megerlia truncata (Linaeus 1767 ) and Pajaudina atlantica (Logan 1988).

Il cambiamento climatico in Italia. Istituzioni scientifiche, politica e discorso pubblico (1988-2012)

La tesi di dottorato ivi presentata si pone come obbiettivo la ricostruzione come questo sapere scientifico (la scoperta del cambiamento climatico antropico sostanziata dalla comunità scientifica di 190 paesi) ha influenzato la ricerca, la politica e il discorso pubblico nel nostro paese, l'italia. Il titolo è indicativo quando riassuntivo: Il cambiamento climatico in Italia. Istituzioni scientifiche, politica e discorso pubblico (1988-2012). Esso definisce in maniera puntuale i temi che si tratteranno: una genealogia di fenomeni storici, politici, culturali nati in nuce alla scoperta di questo cambiamento che influenzerà in maniera determinante il modo in cui viviamo, l'ambiente intorno a noi, i modelli di sviluppo, la sicurezza del nostro abitare, la forma delle nostre città. In ogni paese questa complessa scoperta ha avuto impatti differenti, un portato differente sulla ricerca e sullo sviluppo economico. Quello che in queste pagine si tenta di analizzare è come l'Italia ha assimilato il discorso del cambiamento climatico , in continua evoluzione date le sue infinite ramificazioni, e come ha reagito a livello politico e di ricerca.
