Spontaneous urban weeds: a resource against environmental pollution
2022
Quality of the environment and social well-being, both at a collective and individual level, are closely interrelated issues. It is, in fact, a relationship that invests values of primary importance, such as those relating to human health and safety, heritage and resources to be passed on to future generations. Plant growth and survival can be challenged by harsh urban conditions. Many studies show the persistence of endemic species in built-up areas and document the ecosystem services provided. With this research we wanted to investigate the bioaccumulation of heavy metals such as cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), molibden (Mo), cadmium (Cd), lead (Pb) and mer…
The funerary area and the gallo-roman site of la “Barrière du Lot” in les Martres-de-Veyre (Puy-de-Dôme): old records and new data
2020
Located in the so-called “Barrière du Lot” in the Martres-de-Veyre district, the “Chaumes d’Allier” funerary area consists of a burial site which was excavated between 1851 and 1923. The exceptional state of preservation of the organic remains which were unearthed there (hair, coffins, pieces of clothing, funerary furniture) granted the site its world-wide reputation although, paradoxically, it remained somewhat overlooked as a whole. The recent discovery of unpublished archival materials relating to the 19th-century and early 20th-century excavations, together with an archeo-anthropological study of the documents found at the Bargoin Museum in Clermont-Ferrand, provide a brand-new spatial …
Regional deprivation and non-cancer related computed tomography use in pediatric patients in Germany: Cross-sectional analysis of cohort data.
2016
BACKGROUND: Conflicting findings were observed in recent studies assessing the association between patients' area-level socio-economic status and the received number of computed tomography (CT) examinations in children. The aim was to investigate the association between area-level socio-economic status and variation in CT examination practice for pediatric patients in Germany. METHODS: Data from Radiology Information Systems for children aged 0 to < 15 years without cancer who had at least one CT examination between 2001 and 2010 were extracted in 20 hospitals across Germany. The small-area German Index of Multiple Deprivation (GIMD) was used to assess regional deprivation. The GIMD …
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 …
Variability of the Level of Development of Functopnal Urban Areas
2018
Miejskie obszary funkcjonalne mają istotne znaczenie w realizacji zarówno Krajowej Polityki Miejskiej 2023, jak i terytorialnej polityki rozwoju. Celem badania jest określenie poziomu rozwoju obszarów funkcjonalnych miast wojewódzkich Polski. Badania przeprowadzono z wykorzystaniem metody taksonomicznej w ujęciu dynamicznym obejmującym okres 2005-2015. Podstawę wyznaczenia wielkości taksonomicznych stanowił zestaw wskaźników diagnostycznych ujętych w trzech wymiarach rozwoju: społecznym, gospodarczym i środowiskowym. W ramach badania została podjęta ocena poziomu rozwoju miast centralnych MOF oraz oddzielnie miast i gmin ich otoczenia. Dodatkowo określono poziom rozwoju każdego z wymiarów r…
Bioaccumulation of Trace Elements from Aqueous Solutions by Selected Terrestrial Moss Species
2022
The interrelationship between metal concentrations in mosses and their surroundings prompts research toward examining their accumulation properties, as it is particularly important for their usage in biomonitoring studies that use mosses. In this study, the kinetics of elemental sorption in three moss species (Pleurozium schreberi, Dicranum polysetum, and Sphagnum fallax) were investigated under laboratory conditions. Sorption from metal salt solutions was carried out under static conditions with decreasing elemental concentration. Functional groups responsible for binding metal cations to the internal structures of the mosses were also identified. It was shown that the equilibrium state wa…
Sacelli "dimenticati" nell’area urbana di Akragas
2016
International audience; Between 1927 and 1930, Pirro Marconi investigated a small rectangular structure near house Filippazzo, in the central urban area of Akragas. The presence of a bothros and fragments of female figures with stephane suggested the presence of a small sanctuary or themenos for chthonic deities. The little news published by Marconi and the vague indication of location made us forget the existence of this sanctuary for many years. However, a survey carried out in 2016 allowed to identify the remains of Marconi’s structure, partly covered by ground. At the same time, other little-known structures have been identified. In some cases, their function is still unknown.

Reviewing the role of ecosystems services in the sustainability of the urban environment: A multi-country analysis
2020
The urban environment is characterised by many pressures caused by population growth, transport (and its related emissions), and the damage to green areas. Yet, there is a variety of ecosystem services available in urban areas, which may be deployed to ameliorate the current problems and foster their sustainability. This paper reviews the role of ecosystem services as tools for sustainability, based on an urban setting. It also describes a series of multi-country case studies, where an assessment of their functions using a set of benefits valuation approaches such as health benefits, economic benefits, social benefits and benefits to climate resilience, are provided, along with an appraisal…
