Bryophyte investigations in urban areas: diversity of bryoflora of Erice town.

2016

This work is part of a study of bryophyte floras of Sicilian towns that has highlighted the presence in these environments of interesting taxa from the taxonomic and phytogeographical point of view (1, 2, 3, 4). Given its location, perched at 750 m a.s.l. on the S. Giuliano Mount at the northwestern tip of Sicily, the town of Erice has a climate which, although typically Mediterranean, has a strong wet connotation for the frequent presence of fog, especially in the winter time. These features contribute to creating conditions particularly suited to host bryophytes that grow both on artifacts and on phorophytes present in the city and specially in the Balio urban park. The study has allowed …

Bryophyte diversity in some Sicilian protected areas

2017

The results of some investigations carried out in two Sicilian protected areas characterized by chalky reliefs are reported. These are the Serre di Ciminna and Monte Conca reserves. The Oriented Nature Reserve of Serre di Ciminna is located in northwestern Sicily, in the province of Palermo. Established in 1997 to protect the interesting karst phenomena in a vast macro-crystalline gypsum outcrop of the Messinian age, the series of "collapse valleys" and a swallowtail, the reserve falls within the Rocche di Ciminna, Site of Community Importance (SIC) (code ITA 020024). It includes some habitats of Community interest: pseudo-steppes with grasses and annuals of the Thero-Brachypodietea (code 6…

Detection of protection benefits for predatory fishes depends on census methodology

2021

Marine protected areas (MPAs) are used as fisheries management and conservation tools. Well-enforced no-take zones allow the rebuilding of natural populations of exploited species; however, there is still controversy on the role of buffer zones. The effectiveness of MPAs could be underestimated, as fish population assessments depend largely on traditional methodologies that have difficulties in detecting predatory fish because of their low abundances, their patchy distribution, and their reaction to the presence of divers. The performance of different census methods was compared in assessing the protection benefits for large predatory fishes under different protection levels (i.e. no-take a…

Large eddy simulation model for wind-driven sea circulation in coastal areas

2013

Abstract. In the present paper a state-of-the-art large eddy simulation model (LES-COAST), suited for the analysis of water circulation and mixing in closed or semi-closed areas, is presented and applied to the study of the hydrodynamic characteristics of the Muggia bay, the industrial harbor of the city of Trieste, Italy. The model solves the non-hydrostatic, unsteady Navier–Stokes equations, under the Boussinesq approximation for temperature and salinity buoyancy effects, using a novel, two-eddy viscosity Smagorinsky model for the closure of the subgrid-scale momentum fluxes. The model employs: a simple and effective technique to take into account wind-stress inhomogeneity related to the …

Mujeres rurales profesionales: su evaluación del medio rural en Cataluña y Galicia

2014

Dentro del contexto de las nuevas ruralidades algunas mujeres profesionales han decidido quedarse en el mundo rural para desarrollar su propio proyecto profesional y vital. Es un fenómeno nuevo dado el proceso constante de emigración rural hacia las ciudades que España ha sufrido en el pasado. La investigación la hemos llevado a cabo en zonas rurales de Cataluña y Galicia a través de entrevistas en profundidad. Nuestro objetivo es captar cómo estas mujeres profesionales perciben no solo el mundo rural sino también a las mujeres rurales actuales. Su percepción, fruto de un proceso de formación y experiencia de vida en otros lugares, urbanos, se puede convertir en un espejo para las generacio…

Risk factors for central nervous system tumors in children: New findings from a case-control study

2017

BACKGROUND: Central nervous system tumors (CNS) are the most frequent solid tumor in children. Causes of CNS tumors are mainly unknown and only 5% of the cases can be explained by genetic predisposition. We studied the effects of environmental exposure on the incidence of CNS tumors in children by subtype, according to exposure to industrial and/or urban environment, exposure to crops and according to socio-economic status of the child. METHODS: We carried out a population-based case-control study of CNS tumors in Spain, covering 714 incident cases collected from the Spanish Registry of Childhood Tumors (period 1996-2011) and 4284 controls, individually matched by year of birth, sex, and au…

Aliens Coming by Ships: Distribution and Origins of the Ocellated Skink Populations in Peninsular Italy

2022

The ocellated skink (Chalcides ocellatus) is a widespread lizard, naturally distributed between the Maghreb and coastal Pakistan, with few insular populations in the Mediterranean coastal area. Some populations of this species have also been recorded in peninsular Italy, Campania and Southern Tuscany due to accidental introductions via touristic and commercial routes. In this work, we conducted genetic analyses on mitochondrial DNA COXI, cytb and 16S mtDNA genes on a sample of Italian insular and peninsular populations. Differently from what previously suggested, the nucleus in Portici (Southern Italy) may have originated from Sardinia. The intense trade and touristic traffic between Sardin…

Modelling swarm-intelligent systems for medical applications

2017

Modeling swarm intelligent systems has attracted attention of researchers over the last decade, as the attributes such as self-organization, self-regulation or collective behavior exhibited by the system entities while following a certain set of rules, can be implemented with the aim at investigating complexity of the problems that an individual would be unable to tackle in real world. In this keynote paper, meta-heuristics and paradigms of modeling swarm-intelligent systems will be discussed with respect to their application areas for medical purposes.

LE AREE INTERNE PER LO SVILUPPO DEL TERRITORIO E LA COMPLEMENTARITÀ DI PROGRAMMI E STRUMENTI FRA LE POLITICHE EUROPEE DI SVILUPPO RURALE E DI COESIONE

Le Aree Interne rappresentano un tema particolarmente importante per la programmazione e la spesa dei fondi comunitari nel periodo 2014-2020 perché costituiscono il più grande esempio di complementarità fra le Politiche europee di sviluppo rurale e di coesione. Per lo sviluppo di queste Aree è stata creata una Strategia Nazionale per le Aree Interne (SNAI) che mira alla valorizzazione ed al recupero di tutti quei territori (rurali, montuosi, svantaggiati) dal carattere marginale rispetto alla disponibilità e all’offerta di servizi essenziali. La peculiarità di tale Strategia è quella di promuovere lo sviluppo di aree che sono uniformemente distribuite in tutto il comprensorio nazionale a di…
