Sizing up the role of predators on Mullus barbatus populations in Mediterranean trawl and no-trawl areas

2019

Abstract Fishing leads to drastic changes in ecosystems with a net loss of predatory biomass. This issue has been evidenced from historical ecological studies and from the evaluation of the effects of effective and large marine protected areas. In two fishery reserves off the northern Sicily coast the red mullet Mullus barbatus underwent an impressive biomass increment and a few piscivores fish species recovered after a trawl ban. The red mullet, more than 20% of all demersal fish in the untrawled areas, represented a huge food resource to its potential predators. By contrasting two trawled and two untrawled gulfs we figured out predator - prey relationships through the use of a combined ap…

A century of fishery data documenting the collapse of smooth-hounds (Mustelusspp.) in the Mediterranean Sea

2017

Conservation and management of shark populations is increasingly becoming important in many marine regions, since there is a growing body of evidence showing that several species are threatened and continuing to decline because of unregulated fishing. Quantifying the extent of sharks' decline, the risk of species extinction, and the consequences for marine ecosystems have been challenging and controversial, mostly due to data limitations. In this study, more than one century of multiple-sources of bibliographic records on presence and frequency of occurrence of three species of commercial sharks, the smooth-hounds Mustelus spp., in the Mediterranean Sea were compiled and analysed. Generaliz…

The effects of protection measures on fish assemblage in the Plemmirio marine reserve (Central Mediterranean Sea, Italy): A first assessment 5years a…

2013

This 2-year study was aimed to investigate the early effects of protection measures on fish assemblage in the Plemmirio marine reserve and to evaluate its level of enforcement. Sampling was carried out by means of underwater visual census techniques in four sampling sites within the reserve boundaries and eight outside the reserve. Results showed significant inside/outside differences in the multivariate abundance of fish assemblage. These results were confirmed and exemplified by significant univariate differences between locations for total abundance, Species Richness and diversity of the fish assemblage; values of these metrics were higher inside the reserve than outside. Small fish size…

Le nuove politiche di contrasto in materia di pianificazione fiscale aggressiva, evasione e di elusione fiscale a livello internazionale e dell'Union…

2019

La concorrenza tra i diversi sistemi tributari, nonchè la loro disomogeneità agevola la pianificazione fiscale aggressiva e condotte di evasione e di elusione fiscale, soprattutto da parte dei grandi gruppi di impresa multinazionali, tanto a livello internazionale che dell'Unione europea. Le reazioni più efficaci non sono quelle unilaterali nazionali, bensì quelle adottate in via multilaterale. L'OCSE e la Commissione dell'Unione europea hanno recentemente implementato questa via, cercando, tuttavia, un equilibrio con le esigenze derivanti dalle politiche di attrazione di investimenti e capitali.

"Una storia italiana". Il ventennio berlusconiano nel romanzo postmoderno

2017

Da molti osservatori il ventennio cosiddetto 'berlusconiano' è stato interpretato come un epifenomeno della post-politica, la realizzazione definitiva ed emblematica, drammatica e spettacolare, di una trasformazione sociale e culturale avviatasi negli anni pregressi, non solamente in Italia. In questo intervento, campionando casi esemplari (Di Paolo, Lagioia, Vasta), si prova a verificare come alcuni romanzi italiani abbiano descritto e interpretato questa epoca: individuando alcuni motivi comuni (la condanna dei padri) e calibrando l'efficacia 'politica' di alcune narrazioni degli anni Dieci.

The belief in an unjust world: An egotistic delusion

1996

The main hypothesis of Lerner's just world theory says that people are inclined to think that their physical and social environment is just and that individuals generally get what they deserve and deserve what they get. Contrary to Lerner's assumption, however, it is suggested in the article that in some situations, people may perceive the world as unjust because such a belief has a specific “ego-defensive” compoment for an individual. It is likely, for instance, that the belief in an unjust world, though in itself a legitimate block to success, may be aggrvated in conditions diagnostic for competence and hence can be used as a special form of self-handicapping strategy. This assumption has…

Elusione/abuso del diritto: un quadro d'insieme a margine di una recente sentenza di merito

2020

La sentenza in commento attiene alla configurabilità dell’abuso del diritto, rilevando l’esigenza di individuare se sussistano le condizioni normativamente previste, in particolare la mancanza di sostanza economica nell’operazione posta in essere e il vantaggio fiscale indebito. The ruling in question concerns the abuse of rights. There is the need to identify whether there are the elements provided by law: the lack of economic substance in the transaction put in place and an undue tax advantage.

Análisis de dos relatos maravillosos del ¨Libro del cavallero Zifar¨

2018

En el presente trabajo nos proponemos estudiar la relación entre dos episodios presentes en la primera novela castellana, el Libro del Cavallero Zifar, y la tradición del maravilloso de influencia bretona. Partiremos para ello de un análisis comparativo de ambos episo-dios y el esquema del relato maravilloso propuesto por L. Harf-Lancner. Una vez establecidos los paralelismos oportunos, trataremos de ampliar el marco de comparación y comprender la presencia de estos elementos bretones en la literatura castellana desde una perspectiva más general.

Morphological and biometrical features of Trypanosoma evansi isolates from an outbreak in mainland Spain.

2011

According to several authors, Trypanosoma evansi is a monomorphic trypanosome found exclusively in slender intermediate forms, although additional studies have revealed that many strains present stumpy forms on rare occasions. In a recent T. evansi outbreak in mainland Spain, several atypical forms were observed in blood smear examinations. Molecular procedures were then necessary to confirm the causal agent. Morphological and biometric measures were taken to characterize the different forms of T. evansi. In contrast to published information, the results of this study would indicate that biometrically distinct T. evansi could also be found in the same farm and even in the same animal specie…
