Natural History and impacts of an invasive snake: the horseshoe whip snake, Hemorrhois hippocrepis (Linnaeus, 1758), on Ibiza
2021
The island of Ibiza, located in the Balearic Islands (Western Mediterranean), has remained free of introduced snakes for millennia, unlike the majority of Mediterranean islands. But in 2003, with the Mediterranean garden fad, the entrance of old olive trees to the island became common, and three snake species appeared on Ibiza, traveling as stowaways inside the trunks of the olive trees. The most successful invader was the horseshoe whip snake (Hemorrhois hippocrepis). This PhD dissertation studies the natural history of the invasive population and compares it to the source population’s, in the southern Iberian Peninsula, in order to acquire knowledge that helps fighting against the invasio…
Geophysical surveys for the restoration of Branciforte Palace in Palermo
2019
A multi-methodological and non-invasive geophysical study has been carried out in order to support the restoration project of the historic Branciforte Palace in Palermo. Ground Penetrating Radar profiles and an Electrical Resistivity Tomography ERT, carried out on the floor of the stable of the Palace, allowed to evaluate in detail the state of consolidation of the subsoil, in correspondence of a double row of marble columns, some of which were affected by differential subsidence. These columns have been investigated by means of Ultrasonic Tomography to verify their state of degradation. Moreover Infrared Thermography images of the internal and external walls and of the vaults highlighted d…
Fibronectin urothelial gene expression as a new reliable biomarker for early detection of local toxicity secondary to adjuvant intravesical therapy f…
2020
Background: A marker of urothelial damage could be helpful for early detection and monitoring of local toxicity due to intravesical therapy for non-muscle invasive bladder cancer (NMIBC). The aim of the study was to investigate the correlation between fibronectin (FN) gene expression in bladder washings and local toxicity secondary to adjuvant intravesical therapy. Materials and methods: Patients undergoing adjuvant intravesical therapy for NMIBC and age-matched healthy patients were enrolled. Real time polymerase chain reaction was performed to analyze FN expression in bladder washings. Local toxicity was classified as: 0–1 mild (no medical therapy), 2 moderate (medical therapy and/or inst…

Invasive vascular plant species of oxbow lakes in south-western Poland
2015
Abstract Natural water reservoirs are very valuable floristic sites in south-western Poland. Among them, the most important for the preservation of biodiversity of flora are oxbow lakes. The long-term process of human pressure on habitats of this type caused disturbances of their biological balance. Changes in the water regime, industrial development and chemisation of agriculture, especially in the period of the last two hundred years, led to systematic disappearances of localities of many plant species connected with rare habitats and also to the appearance of numerous invasive plant species. They are: Azolla filiculoides, Echinocystis lobata, Erechtites hieraciifolia, Impatiens glandulif…
Inventory of the non‐native flora of Italy
2009
In this paper we present a comprehensive inventory of the non‐native vascular flora of Italy, which was produced within the project “A survey of the Italian non‐native flora”, funded by the Italian Ministry for the Environment. Previously published floristic accounts were the main source of information. Historical records were critically revised and integrated with recent literature, data from herbaria and some unpublished information, so as to obtain a complete, up‐to‐date catalogue of the non‐native vascular plant species that occur spontaneously in Italy. The inventory lists 1023 non‐native species and subspecies, which account for 13.4% of all the Italian flora. The Italian non‐native f…
Vegetation dynamics within afforested coastal areas: regeneration by native species or invasion by alien species?
2017
During the last century, massive reforestation projects along the dunes of the southern Sicily have been carried out. Such interventions, far from being in line with the current trends of close-to-nature silviculture, are, however, particularly interesting to assess the vegetation dynamics in afforestation areas. Furthermore, these kind of interventions may determine two opposite effects, that is renaturalization by native woody species or invasion by alien species. Acacia spp. are among the most widespread and prominent invaders within Mediterranean-climate areas, where they have already shown the capability to deeply change the characters and the functioning of native ecosystems. For inst…
German neuroendoscopy above the skull base
2009
Endoscopy plays an important part in current minimally invasive neurosurgery. The concepts, indications, and standards of current neuroendoscopy were developed in the beginning of the 1990s by several groups of neurosurgeons. Several factors contributed to its success and acceptance, including technical development, influence of other disciplines, and adaptation to neurosurgical requirements. This historical survey focuses on the period when this technique initially emerged, including the scientific discussions of each group as well as the arguments and reasons that led to present intraventricular neuroendoscopy. Interestingly, despite the almost independent development of neuroendoscopic s…
