First record of the genus Thyreosthenius (Araneae: Linyphiidae) from the Iberian Peninsula with notes on the host preference of the myrmecophilic T. biovatus
No full textThe presence of the spider genus Thyreosthenius Simon, 1884 (Linyphiidae) is for the first time confirmed in the Iberian Peninsula with an observation of the myrmecophile species T. biovatus (O. Pickard Cambridge, 1875). Four adult females and two sub-adult male specimens were collected inside mound nests belonging to the red wood ant species Formica lugubris Zetterstedt, 1838 in the Aragon and Catalonia regions of Spain. This represents the second known record of an occurrence of T. biovatus in association with F. lugubris, and the first for Continental Europe. In addition, the existing information on the host preference of this species is reviewed and discussed in relation to the new data from the Spanish Pyrenees
CIRCO. Un immaginario di città ospitale
No full textIl volume restituisce i quattro anni di ricerca CIRCO, acronimo di Casa Irrinunciabile per la Ricreazione Civica e l'Ospitalità; una ricerca elaborata in seno al Laboratorio di Progettazione Architettonica e Urbana della Laurea Magistrale in Progettazione Urbana del Dipartimento di Architettura di Roma Tre, che propone un ripensamento degli spazi di accoglienza di migranti transitanti a popolazioni mobili a partire dal riuso del patrimonio immobiliare romano abbandonato sottoutilizzato. Alla base della ricerca è la proposta di trasformazione del patrimonio dismesso in una rete metropolitana di condomini interculturali fondati sull'ospitalità. Il volume restituisce i quattro anni di ricerca attraverso gli scritti di chi ne ha preso parte e raccogliendo, inoltre, i contributi dei numerosi esperti, operatori, docenti, e ricercatori che hanno contribuito, con il loro punto di vista e le loro competenze, ad arricchire e orientare le prospettive della ricerca. Oltre ai membri del Laboratorio CIRCO hanno scritto nel volume: F. Abissi, A. F. L. Baratta, V. Bilardello, F. Bonadonna, C. Cacciotti, V. Calderone, M. Catena, D. D’Attilio, C. Davoli, I. Di noto, G. Fiocca, F. Giani, G. Guiducci, Leroy SPQR’Dam, G. Longobardi, G. Marzocchi, I. Mattioli, M. Ottaviani, S. Paoluzzi, F. Petrelli, C. Petrocelli, E. Rieti, L. Romito, G. Sokoll, A.

No full textExploring mitogenome evolution in Branchiopoda (Crustacea) lineages reveals gene order rearrangements in Cladocera
No full textThe class Branchiopoda, whose origin dates back to Cambrian, includes ~ 1200 species which mainly occupy freshwater habitats. The phylogeny and systematics of the class have been debated for long time, until recent phylogenomic analyses allowed to better clarify the relationships among major clades. Based on these data, the clade Anostraca (fairy and brine shrimps) is sister to all other branchiopods, and the Notostraca (tadpole shrimps) results as sister group to Diplostraca, which includes Laevicaudata + Spinicaudata (clam shrimps) and Cladoceromorpha (water fleas + Cyclestherida). In the present analysis, thanks to an increased taxon sampling, a complex picture emerges. Most of the analyzed mitogenomes show the Pancrustacea gene order while in several other taxa they are found rearranged. These rearrangements, though, occur unevenly among taxa, most of them being found in Cladocera, and their taxonomic distribution does not agree with the phylogeny. Our data also seems to suggest the possibility of potentially homoplastic, alternative gene order within Daphniidae
Molecular systematics and phylogenetics of the spider genus Mastigusa Menge, 1854 (Araneae, Cybaeidae)
No full textThe palearctic spider genus Mastigusa Menge, 1854 is characterized by a remarkable morphology and wide ecological variability, with free-living, cave dwelling and myrmecophile populations known. This genus has a long and tangled taxonomic history and was placed in different families in the past, all belonging to the “marronoid clade”, an informal grouping of families characterized by the lack of strong synapomorphies. Three species are currently recognized, but their identity and circumscription has been long debated. A molecular approach was never applied for trying to solve these uncertainties, and doubts still remain both about its phylogenetic placement and about the taxonomic status of the described species. For the first time the genus Mastigusa is included in a molecular phylogenetic analysis and strong support is found for its placement within the family Cybaeidae, in sister relationship with the genus Cryphoeca Thorell, 1870. An analysis of Mastigusa populations spanning across the distribution range of the genus identifies a high and previously overlooked genetic diversity, with six distinct genetic lineages showing a strong geographic pattern. Divergence times between Mastigusa and its sister genus and between the distinct Mastigusa lineages are estimated, and the groundwork is laid for a taxonomic revision of the species belonging to the genus
