The following study intends to introduce a forgotten poet, novelist and critic, Karel Bačkovský. Consistent chronological focus on his texts serves as a basis for re/construction and outline of certain symptomatic moments and characteristic topics of contemporary discussions (social role of art and artists, tension between reality and imagination, feminism, relations to the past) - through the specific perspective of the author. and Článek zahrnuje poznámkový aparát pod čarou
The philometrid nematode, Philometra saltatrix Ramachandran, 1973, is redescribed from male and female specimens collected from the ovaries of the marine fish (bluefish) Pomatomus saltatrix (L.) (Pomatomidae, Perciformes) from the Tuscan Sea, Italy. The light and scanning electron microscopical examination made it possible to study in detail the morphology of this so far little known species. For the first time, the actual structure of the male cephalic and caudal ends is described. The male possesses 14 small cephalic papillae arranged in two circles, the spicules are 84-111 µm long and the gubernaculum, 75-84 µm long, has its distal portion provided with dorsal transverse lamella-like structures. The caudal end of subgravid females bears two very small, hardly visible lateral papilla-like projections. This is the first record of P. saltatrix, a species originally described from the West Atlantic, from the Tuscan Sea and the second one in the Mediterranean region.
Several studies address the question of which forest attributes are most important for the conservation of biodiversity. Unfortunately, there are no unequivocal answers because the response of a biological group to changes in forest structure depends on its natural history and scale of organization. It is important to increase our knowledge of the potential relationships between under studied groups of species and forest variables in order to adopt timber harvesting strategies not detrimental to biodiversity, especially in old-growth forests. We assessed the importance of 10 forest attributes and old-growth for Psychidae (Lepidoptera) species and communities. Research was carried out in 12 forest stands in a mountainous beech dominated landscape in southern Italy, in the middle of the Mediterranean Basin. Samples were collected in 2001 and 2013 and data were merged after pairwise comparison analyses that confirmed the long term stability of communities. Correspondence Analysis, Cluster Analysis and non-parametric Spearman Rank Order Correlation were used to identify determinants of Psychidae abundance and diversity. We collected 2,732 Psychidae belonging to 8 species. Correspondence analysis identified old-growth as the main determinant of communities. Most significant attributes for individual species were beech dominance, diameter at breast height and its standard deviation. For Taleporia defoliella there were positive correlations with these forest parameters, whereas for Psyche crassiorella the correlations were negative. This study underlined the importance of forest attributes associated with old-growth forests for sustaining biodiversity. These findings indicate the need to incorporate these attributes in forest planning, especially those aspects that are easily recognizable such as the number of large trees., Stefano Scalercio, Teresa Bonacci, Rosario Turco, Vincenzo Bernardini., and Obsahuje bibliografii
Social housing in Italy, its historical and recent developments, and its criticalities are discussed considering both the pre- and the post-crisis period. The main effects of the crisis on Italian households and the exacerbating of housing problems are also analysed. A critical review of the main policy instruments implemented before and after the crisis is provided, with a special focus on new models of intervention. It is not clear how the housing needs of low income households will be addressed in the near future. Traditional public-managed social housing has been left with insufficient resources while the newly-built affordable housing sector is mainly targeting mid-income households. Several new policy instruments have been deployed and billions of euros invested. Nevertheless, it is still difficult to observe a consistent strategy oriented to increasing the level of social protection in the housing domain, beyond the conventional management of “emergencies”.
The distribution of Sphaerospora dicentrarchi Sitjà-Bobadilla et Alvarez-Pellitero, 1992 and S. testicularis Sitjà-Bobadilla et Alvarez-Pellitero, 1990, myxozoan parasites of European seabass Dicentrarchus labrax (L.), was investigated in different farming systems in Italy. In total, 1406 fish were examined. High S. dicentrarchi prevalence was observed in all the farming systems involved in this survey (extensive farms: 51.5%; intensive farms: inland 59.6%, inshore floating cages 76.2%, offshore floating cages 41.6%) except for submersible cages (7.4%). S. testicularis was detected only in nine male fish from two intensive farms. The epidemiology and pathological effects of the parasites are discussed.
This paper presents biological notes on two species of Orthoptera: Tettigoniidae that emerged from old spongy-woody galls of Dryocosmus kuriphilus Yasumatsu, 1951 collected in Sicily (Italy) in April 2015: Leptophyes sicula Kleukers, Odé et Fontana, 2010 (Phaneropterinae) and Cyrtaspis scutata (Charpentier, 1825) (Meconematinae). Between the end of April and the first few days of May a total of 30 neanids emerged from the galls, were reared and their life-cycle recorded. While L. sicula laid eggs in groups, C. scutata laid single eggs inside the galls; both species in a few years have adapted to exploiting this new shelter for egg laying. No interaction with the gall inducing insect was noted., Giuliano Cerasa, Bruno Massa., and Obsahuje bibliografii
We studied a natural infection of the oligochaete Branchiura sowerbyi Beddard, 1892 with the Raabeia-type actinosporean stage of Myxobolus lentisuturalis Dyková, Fiala et Nie, 2002 which infected goldfish Carassius auratus auratus (L.) in Italy, using molecular analysis of the SSU rRNA gene. The existence of intraoligochaete development shows that this parasite follows the life-cycle pattern described by Wolf and Markiw (1984) for Myxobolus cerebralis. Histological examinations of the goldfish infected by M. lentisuturalis showed at low magnification the presence of two bilateral crescent-shaped masses in the dorsal epaxial muscle. These lesions were not circumscribed, presented irregular edges and infiltrated the underlying bundles of skeletal muscle and interstitial tissue. At higher magnification, disappearance of muscle fibres and substitution of the muscle tissue with Myxobolus spores and plasmodia were observed.

This article evaluates once more the historiographic and literary images of John of Bohemia and his son Charles IV in Italian texts from the 14th and early 15th centuries. What we find is a peculiar mixture of criticism and apotheosis, sometimes stated by the same authors, depending on the point in time they were writing, and of course the expectations of their potential readers. While John of Bohemia faced overwhelming expectations from Dante after the death of his father, he was branded a naïve yet greedy papal mercenary from the beginning of his Italian Expedition in the early 1330s. His son was more successful in avoiding negative stereotypes and harsh criticisms during his Italian expeditions in his youth, as well as in 1354/55 and 1368/69. In the end, however, even chroniclers that are traditionally considered to have had a positive view of the Luxemburg king and emperor harshly rejected his political actions in Italy. Most of the time, this is connected with the financial interests all foreign monarchs had when establishing temporary rulerships in Italian cities, and the monetary pressures this bore on their citizens; the worn-out cliché, both of contemporaries and historical researchers, that labelled foreign, Central European monarchs as barbaric intruders, could hardly be confirmed. Charles and his father are blamed for being unable to solve the structural problems of Italian and Imperial politics.
The genus Gobio in Italy was represented by the endemic species G. benacensis. The original distribution of this species was the Padano-Venetian district, but since a long time it was introduced in central Italy. Introductions of alien species to Italy during the last 10 years brought the sudden introduction of the Danubian G. gobio. Genetic and morphological analyses revealed the extensive presence of G. gobio, which rapidly colonised several rivers in Italy causing the progressive decline of G. benacensis, which now should be considered as an endangered species. Among examined populations those found in the Tagliamento River and transplanted in the Ombrone River represent genetic reservoirs of this species which will probably disappear in northern Italy.
