Do invasive macroalgae influence biodiversity and abundance of Amphipod Crustaceans ?
2013
Amphipods are an essential element of the food web in marine coastal environments, and represent a good indicator of the health of the ecosystems. The composition of amphipod assemblage is often linked to algal coverage, in which the benthic species find refuge from predators and a great availability of food resources. Within the management and conservation of natural environments, one of the main problems is currently represented by the invasion of non-indigenous species, which modifies native communities. This research compares the amphipod fauna associated with Asparagopsis taxiformis (Delile) Trevisan de Saint-Léon, a non-indigenous red macroalga widely distributed along the west coast …

An assessment of regulation, education practices and socio-economic perceptions of non-native aquatic species in the Balkans
2021
Alongside climate change, the introduction of non- native species (NNS) is widely recognized as one of the main threats to aquatic biodiversity and human wellbeing. Non-native species and biodiversity are generally low priority issues on the political agendas of many countries, particularly in European countries outside the European Union (EU). The objectives and tasks of this study were to address the policy regulation, education level, education practices, and socioeconomic perceptions of NNS in the Balkans. A questionnaire based survey was conducted in Albania, Bosnia and Herzegovina, Montenegro, North Macedonia and Turkey (Balkan EU candidate and potential candidate members), in Croatia…
Searching for the competitive ability of the alien seagrass Halophila stipulacea with the autochthonous species Cymodocea nodosa
2023
The tropical seagrass Halophila stipulacea (Forsskål) Ascherson, 1867 entered in the Mediterranean Sea through the Suez Canal more than 100 years ago. In coastal-marine ecosystems the spatial niche of H. stipulacea is often overlapped with that of native Mediterranean Sea seagrasses and therefore it might out-compete them. Aiming to better understand its invasiveness potential, we monitored a Southern Mediterranean shallow coastal-marine water habitat from August 2010 to August 2011, where H. stipulacea co-occurred with the native seagrass Cymodocea nodosa (Ucria) Ascherson, 1870. Besides, the year-round dynamics of H. stipulacea was also monitored in four periods. To test the hypothesis th…
INDAGINI NON INVASIVE SU ALCUNE COLONNE DELLA VILLA ROMANA DEL CASALE, A PIAZZA ARMERINA
2012
Alcune indagini non invasive sono state eseguite a supporto delle prove di verifica delle colonne prospicienti il Corridoio della Grande Caccia della Villa Romana del Casale, a Piazza Armerina. Scopo del progetto di indagine è la localizzazione di eventuali perni metallici e anomalie interne nelle dieci colonne che separano il Corridoio della Grande Caccia dal Peristilio e valutare il livello di portanza delle singole colonne. A tale scopo sono state eseguite indagini georadar e soniche. Le indagini georadar sono state effettuate utilizzando un apparecchiatura munita di antenna con frequenza centrale di 1000 MHz in modalità monostatica, per ogni colonna, sono stati acquisiti 4 profili verti…
TECNICHE NON INVASIVE DI SUPERFICIE E DI VOLUME PER IL MONITORAGGIO STRUTTURALE DELLE SCULTURE MARMOREE
2014
L’analisi delle proprietà strutturali di una scultura in marmo, attraverso l’impiego di tecniche di indagine non invasive da realizzare direttamente in situ, è di fondamentale importanza per la valutazione dello stato di conservazione e, conseguentemente, per il monitoraggio di eventuali fenomeni di degrado che possono compromettere l’integrità dell’opera d’arte. Lo studio condotto sul bassorilievo raffigurante la Madonna con Bambino conservato presso la Cappella del Monastero delle Clarisse Totus Tuus di Gorizia ha permesso di verificare la complementarietà delle informazioni restituite da tecniche di analisi della superficie (acquisizioni in fluorescenza ultravioletta) e tecniche di anali…

Fungal infections in transplantation patients
2003
Invasive fungal infections have became one of the principal obstacles to successful solid organ and bone marrow transplantation. The natural history and incidence of systemic fungal infection varies with the type of organ transplanted and the immunosuppressive therapy administered; the majority of infections occur within the first two months after transplantation. The most common fungi that cause disease in transplant recipients are Candida spp. and Aspergillus spp. The clinical presentations of fungal infections in solid-organ transplant recipients are non specific and often overlap with other infectious and non infectious processes; for this reason it's important maintain a high index of …
