...The invasiveness of the species can be attributed to some of its biological and ecological characteristics, such as its high tolerance to environmental degradation and its more rapid growth in weight and length compared to native Barbus species (Lorenzoni et al. 2006a)....

...The sub-basins under study differ in regard to their geomorphological characteristics and water quality (Lorenzoni et al. 2006b)....

...As in previous studies (Lorenzoni et al. 2006b; Carosi et al. 2015, 2016), the Padanian barbel Barbus plebejus Bonaparte, 1839 was considered also indigenous to the Tiber River basin, even if its original range is still uncertain (Bianco 2003)....

...Currently, the natural composition of these fish communities is profoundly altered by the introduction of many alien species, including the European barbel, Barbus barbus (L., 1758) (Lorenzoni et al. 2006a; Carosi et al. 2015)....

...…the fish assemblage was composed almost exclusively by the brown trout, Salmo trutta complex, and from the downstream reaches, where water pollution and the presence of many exotic species (Lorenzoni et al. 2006b; Carosi et al. 2015, 2016) have made the environment unsuitable for the Tiber barbel....

...…by the rheophilic cyprinids species typical of the mid-upper reaches of the Tiber river (B. tyberinus, P. genei, R. rutilus and S. squalus) (Lorenzoni et al., 2006); in contrast, in 2010, the fish community of Anghiari was constituted entirely of salmonids and the only species sampled were…...

...In Central Italy, S. trutta typically inhabits the small tributaries of the Tiber rver localized in mountain because this species is a frigostenothermal stenoxybiont and less adapted to the environmental characteristics of the main stretch of the Tiber river (Lorenzoni et al., 2006)....

...The original fish community of the upper part of Tiber river consists of species with a high conservation value (Lorenzoni et al., 2006) comprising many of the endemics of the A cc ep te d A rti cl e www.jlimnol.it Tuscany and Lazio district (Bianco, 1996) and…...

...…may represent a source of diffusion of various exotic species in the downstream river stretches (Lorenzoni et al., 2004) potentially raising the already high level of zoogeographic pollution that now characterises the Tiber river (Bianco, 1990; Lorenzoni et al., 2006, Giannetto et al., 2012)....

...For the river Tiber basin the CCA results confirm that the alteration degree of the fish communities is closely linked to the longitudinal gradient and this trend, already highlighted by previous research (Lorenzoni et al., 2006), it is confirmed in time....

...The same analysis were carried out in the past (Lorenzoni et al., 2006; Giannetto et al., 2012) and one of the purposes of this research was to evaluate the changes occurred over time....

...Fish assemblage composition varied along the Tiber River according to environmental variables, a common feature of stream fish communities (HUET, 1949, 1954, 1962; VANNOTE et al., 1980; MINSHALL et al., 1985; CHANGEUX, 1995)....

...Habitat controls the longitudinal distribution of fish, and changes in habitat characteristics are often associated with changes in the composition of the fish assemblage (HUET, 1949, 1954, 1962; VANNOTE et al., 1980; MINSHALL et al., 1985; MORIN and NAIMAN, 1990; CHANGEUX, 1995; BELLIARD et al., 1999; ARUNACHALAM, 2000; BUNN and DAVIES, 2000)....

...Another problem is the introduction of exotic species, which is considered as one of the most important but least studied factors that disrupt aquatic ecosystems (MILLS et al., 1993; LEACH, 1995; LODGE et al., 2000; MACK et al., 2000; BYERS et al., 2002)....
