Ancient or recent? Insights into the temporal evolution of the Bruniaceae
2008
AbstractThe Bruniaceae are a South African plant family endemic to the Cape Floristic Region with one geographic outlier (Raspalia trigyna) in the Natal Province. Recent molecular phylogenetic analyses have cast new light upon inter- and intra-generic relationships within the family. The present work uses those data to gain insights into the temporal evolution of Bruniaceae by inferring a molecular clock. For calibration, the inferred age of Berzelia cordifolia (3–5My) was used, based on its distribution restricted to the geologically young limestone area around Bredasdorp. The results are consistent with the purported Cretaceous age of the family (‘palaeoendemics’), but also suggest that m…
Ocena przestrzennego rozmieszczenia parków narodowych i obszarów chronionego krajobrazu w państwach Europy Środkowej na tle prowincji fizycznogeograf…
2020
Na podstawie analizy przestrzennego rozmieszczenia parków narodowych i obszarów chronionego krajobrazu Polski (parki krajobrazowe), Czech, Słowacji i Węgier oceniono czy tworzone w poszczególnych krajach systemy ochrony przyrody i krajobrazu są reprezentatywne również dla prowincji fizycznogeograficznych w granicach państw. Stwierdzono znaczną reprezentatywność w prowincjach głównie górskich i wskazano na dalsze możliwości ochrony. Na podstawie oceny stopnia integracji systemów ochrony przyrody i krajobrazu w rejonach przygranicznych określono obszary, które powinny uzupełnić system. Między poszczególnymi krajami występują różnice w przestrzennej organizacji parków narodowych i obszarów och…
Multi-criterial approaches for the inventory and the evaluation of traditional cultural landscapes
2008
The Mediterranean environment is characterized by an high variability in ecological features and by a rich biodiversity, whose interaction has generated complex agro-forestry systems. The resulting cultural landscapes can represent a remarkable trait of Italian landscape. Nonetheless, since several decades they are at risk mainly owing to the consequences of cultural intensification, that has turn out in new cultural models, i.e. specialized high density agronomic plantation, or in a progressive abandonment of agricultural land. In order to prevent the degradation or loos of these particular ecosystems, it becomes a priority to adopt measures for their preservation and promotion. Regardless…
Dialetto e Linguistic Landscape: il caso delle insegne delle attività commerciali a Palermo
2017
Il presente contributo si propone di analizzare la presenza e l’uso del dialetto nel Linguistic Landscape (LL) di Palermo, con particolare riferimento al ricorso di tale codice sulle insegne delle attività commerciali della città. Si tratta di una tipologia “testuale” di certo tra le più rappresentative del LL, perché le insegne delle attività commerciali si “depositano” in modo più duraturo sull’incostante e mutevole “palinsesto” urbano (diversamente da quanto avviene, ad esempio, con i cartelloni pubblicitari). In particolare, l’analisi si concentrerà sui seguenti aspetti: a) il riferimento al mondo tradizionale in cui il dialetto assume una componente essenzialmente evocativa, più o meno…
The Value of the Useless in the Urban Landscape of Small Islands
2015
Abstract. In the variety of the Italian landscape-cultural mosaic, the morphology of Favignana (Egadi Islands) is the outcome of the long-term relationship between natural environment and human actions that has drawn both natural and urban landscape. This relationship, that constitutes the Favignana’s architectural and landscape heritage, is often denied or forgotten because of transformations caused by a new demand of efficiency (usefulness?) in reference to an economic policy based on the tourism-related activities. In this case-study, the Analytic Network Process (ANP) (selected among the Multicriteria Analysis techniques because of its holistic approach) has applied to support the choic…
Fluid escape structures in the Graham Bank region (Sicily Channel, Central Mediterranean) revealing volcanic and neotectonic activity
2016
In the Sicily Channel, (Central Mediterranean), two geodynamic processes overlap each other, the Maghrebides- Apennines accretionary prism and the Sicily Channel rift. Moreover, the northwestern sector (Banks sector) is characterised by an irregular seafloor morphology linked to the recent volcanic and tectonic activity.In order to discriminate the role exerted by both the processes in the morphostructural setting of the area we used a dataset of both high and very high resolution single-channel and multi-channel profiles, acquired in the frame of the RITMARE project respectively with CHIRP and sparker, and airgun sources, and high resolution (5 m cell) morpho-bathymetric data. The data all…
Natural assets in the right-of-way of A-4 Motorway in the Góra Świętej Anny Landscape Park, Opole Region
2014
Construction of the A-4 Motorway section in the Opole Region begun in Summer 1997. Very soon vigorous resistance of ecological NGOs was encountered. The bone of contention was the section of motorway that passes through the Góra Świętej Anny Landscape Park and verges the natural reserve of strict protection Ligota Dolna where rare species of thermophilic plants are sheltered. Between 2011 and 2013 a detailed mycological, geobotanical, floristic and fauna research took place within the right-of-way of the A-4 Motorway section crossing the Góra Świętej Anny Landscape Park in the Opole Region. The survey revealed several rare and protected species of fungi, plants and animals along the road, i…
Phylogeographic patterns of steppe species in Eastern Central Europe: a review and the implications for conservation
2016
The phylogeography of species associated with European steppes and extrazonal xeric grasslands is poorly understood. This paper summarizes the results of recent studies on the phylogeography and conservation genetics of animals (20 taxa of beetles, butterflies, reptiles and rodents) and flowering plants (18 taxa) of such, "steppic" habitats in Eastern Central Europe. Most species show a similar phylogeographic pattern: relatively high genetic similarity within regional groups of populations and moderate-to-high genetic distinctiveness of populations from currently isolated regions located in the studied area. This distinctiveness of populations suggests a survival here during glacial maxima…
Correlation between polymorphism of TYMS gene and toxicity response to treatment with 5-fluoruracil and capecitabine
2020
Tumorigenesis is a multiphasic process in which genetic alterations guide the progressive transformation in cancer cells1. In order to evaluate the possible correlation between some gene variants and the risk of the toxicity development onset, two of the polymorphisms of the thymidylate synthase (TYMS), rs34743033 (2R/3R) and rs16430 (DEL/INS) were investigated. We enrolled in our study 47 patients from the Hospital of Sicily. Our preliminary findings suggest that there could be a linkage between the genotypes discussed and the development of the toxicity following the chemotherapy treatment. These results need to be confirmed by further studies, however this short paper offers some initial…
Lesser kestrel diet and agricultural intensification in the Mediterranean: An unexpected win-win solution?
2018
Abstract Farmland bird species have suffered dramatic declines in recent decades, especially in Mediterranean areas. The intensification of agricultural practices has led to reduced invertebrate prey, which represent the bulk of the diet of many farmland birds. In this study, we investigated the spatial and temporal variation in the diet of the lesser kestrel (Falco naumanni) during the breeding season, monitored over a five-year period between 2006 and 2013 in the Gela Plain (Sicily). Our aim was to understand whether, and to what extent, farming practices affected the reproductive outputs of this predominantly insectivore bird in order to find a profitable compromise between conservation …
