First record of Hemidiaptomus (Gigantodiaptomus) superbus (Schmeil, 1895) in Italy, with notes on distribution and conservation status (Copepoda, Cal…

2011

Hemidiaptomus (Gigantodiaptomus) superbus (Schmeil, 1895) was found in a temporary pool in the Pineta di Classe coastal pine-wood (Ravenna, northern Italy). This is the first official record of a species belonging to the subgenus Gigantodiaptomus of Italian fauna, and it widens the known distribution of this rare diaptomid to the Mediterranean basin. In order to supply data on this rare and poorly known species, original drawings for the Italian population have been provided, and some overlooked morphological features have been highlighted. In light of the growing evidence of the existence of a number of cryptic species in the Diaptomidae family, and considering the variability observed in …

Distribution of recent ostracods in inland waters of Sicily (Southern Italy)

2006

From 2003 to 2005, freshwater ostracods were sampled in 67 water bodies of mainland Sicily (Provinces of Agrigento, Caltanisetta, Catania, Enna, Palermo, Messina, Ragusa, Siracusa and Trapani) located from sea level up to 1300 m a.s.l. This survey took into account streams, springs, wells, but especially temporary and ephemeral habitats (e.g., flooded meadows, temporary ponds). The aim of this research was to give the first comprehensive picture of the regional ostracod fauna and establish relationships between the distribution of ostracod species and some habitat features. Altogether, 21 ostracod taxa belonging to five families (Candonidae, Ilyocyprididae, Cyprididae, Notodromadidae, and L…

Studies on the zooplankton of the deep subalpine Lake Garda

1999

The specific composition and seasonal dynamics of the zooplankton of Lake Garda have been studied through monthly surveys in two annual cycles (December 1994-November 1995 and January-December 1997). The assemblage is largely dominated by Copipo-diaptomus steueri, a typical calanoid presently identified in deep (Garda, Iseo) and shallow lakes of NE Italy and in the hinterland of the central Adriatic region (Dalmatia and Marche Region). Cladocerans and the smaller rotifers represent a significant component of the zooplankton from spring to autumn. A re-examination of the results obtained in previous studies does not seem to demonstrate substantial shifts in the composition of the dominant sp…

Experimental test on the use of MS-222 for ostracod anaesthesia: concentration, immersion period and recovery time

2010

Anaesthesia of animals may be useful for different purposes, particularly for veterinary reasons or in experimental research, for manipulation or treatment of immobilized but alive animals. Its use in crustaceans is not uncommon, but it has never been described for Ostracoda. We provide brief and preliminary guidelines on the use of the tricaine mesylate (MS-222) on the widespread freshwater ostracod Eucypris virens and we show that this compound is an effective anaesthetic used as a bath treatment at minimum concentrations of 500 mg L-1. This value is considerably higher than that recommended for other aquatic animals like fish. Recovery time, ranging from 5 to 15 minutes, is mostly determ…

La literatura perduda de Joan Roís de Corella: les fonts

2008

The lost literature of an author provides data that, in spite of being partial, are important to better understand his preserved work and the complexity of his literary work. This article offers an approach to the losses experienced by Joan Roís de Corella’s literature down the centuries, in the full meaning of the term. It focuses on the analysis of the sources that supply information to establish a catalogue of these losses, as a starting point for subsequent work concerning the causes and periods of the disappearances.

Indagando in quali modi l’interesse per l’omosessualità ha informato di sé alcune branche della sociologia, il saggio indica le «aporie» e gli intenti normalizzanti di una disciplina spesso volta alla tematizzazione della (omo)sessualità principalmente in quanto tabù e devianza.

What do we know about the sporting experiences of gender and sexual minority athletes and coaches? A scoping review

2020

Scholarship on gender and sexual diversity in sport has advanced during the last decade and it is nowadays recognised that we need a better understanding of how to facilitate inclusive sport cultures that allow all people to participate as themselves. The purpose of this scoping review was to map research activity on the sporting experiences of gender and sexual minority (GSM) athletes and coaches, identify gaps in the literature and provide suggestions for future research, policy and practice. Our literature search in four different databases yielded 58 relevant studies. Based on their focal areas, five dominant interconnected themes were identified: (1) identity, (2) discrimination, (3) c…

Behavioural thresholds of blue tit colour vision and the effect of background chromatic complexity

2020

Vision is a vital attribute to foraging, navigation, mate selection and social signalling in animals, which often have a very different colour perception in comparison to humans. For understanding how animal colour perception works, vision models provide the smallest colour difference that animals of a given species are assumed to detect. To determine the just-noticeable-difference, or JND, vision models use Weber fractions that set discrimination thresholds of a stimulus compared to its background. However, although vision models are widely used, they rely on assumptions of Weber fractions since the exact fractions are unknown for most species. Here, we test; i) which Weber fractions in lo…
