Occurrence, distribution and bibliography of the medicinal leech Hirudo verbana Carena, 1820 (Hirudinea, Hirudinidae) in Sicily (Italy)
2019
Author(s): Marrone, Federico; Canale, Domenica Emanuela | Abstract: The occurrence of the medicinal leech Hirudo verbana in the inland waters of Sicily has been lately overlooked. In the present note, the occurrence and distribution of this species is reviewed based both on the review of the available literature data and field collecting. Although a noteworthy reduction in the distribution range of the species seems to have taken place in Sicily in the course of the XX century, Hirudo verbana was confirmed to be still present in several sites located both within and out of Natura2000 sites. The Sicilian populations of the species should be included in the frame of the monitoring activities …

Multi-Destination Trips and Tourism Statistics: Empirical Evidences in Sicily
2012
Abstract The knowledge of the actual magnitude and main features of tourism flows in a given destination is an essential prerequisite for the evaluation of tourism impacts and externalities. Indeed, many pleasure trips are often characterized by the visit to more than a single destination. Although the topic is well-documented in literature, the empirical results are limited to a few pioneering studies. The lack may be attributable to the failure of tourism organizations to collect data on multi-destination trip behaviour. This can be seen, for example, in the system of European statistics on tourism (according to the Council Directive 95/57 EC), where information on the average number of v…
Multi-destination trips: A survey on incoming zourism in Sicily
2012
Many pleasure trips are often characterized by the visit of more than a single destination. Despite the topic is well documented in literature, the empirical studies are limited to a few pioneering studies. This lack may be attributable to the failure of tourism organizations to collect data on multi-destination trip behaviors, as it results, for example, from the system of European statistics on tourism (according to the Council Directive 95/57 EC), where no information on the average number of destinations visited within a single trip are provided. This paper aims to analyze the main implications of multi-destination trips both on tourism statistics and in tourism planning, and to describ…
