“…Highest species richness and diversity is generally known from these separated habitats (cf. Bornette et al, 1998;Dawson & Szoszkiewicz, 1999;Ludovisi et al, 2004;Ward & Tockner, 2001), what correspond with our results (Fig. 1).…”

“…Main pattern of aquatic macrophytes is closely related to morpho-hydrology and trophic state of habitats (Ludovisi, Pandolfi, & Taticchi, 2004), which change in response to the regulation of the anastomosis of rivers (Chauhan & Gopal, 2005;Janauer, 2001). The typology of the former channels based on their connectivity with the river and groundwater (permanent connection, temporal connection and connection through river flood) in relation to plant species richness was used for the Rhoˆne River in France (Bornette, Amoros, & Lamouroux, 1998).…”

The aim of the study was to evaluate pattern of the aquatic macrophyte species distribution along the Danube fluvial corridor in Slovakia, and to identify the impact of environmental abiotic parameters on macrophyte species diversity. Field sampling was performed in the period 1999-2005 from the boat. Aquatic habitats were divided into 365 survey unit (SU). The survey of aquatic macrophytes and abiotic parameters followed the European standard approach EN 144184 2003. The plant mass estimate (PME -a semi-quantitative estimation of the amount of individual species in a SU, which takes into account three-dimensional development of plant stands) was estimated according to a five-point-scale in each SU; environmental pattern, were assessed over six abiotic parameters (river km, bank type, sediment type, flow velocity class, land-use type, and heavily man-modified water bodies). Altogether, four hydrologic connectivity types of aquatic habitats were distinguished: the Danube River, Open Arms, Separated Arms, and Seepage Water-bodies.In total, 54 aquatic macrophytes were recorded for the whole data set of the Danube fluvial corridor. The PME data of true aquatic macrophytes and the length of SUs created a basis for numerical derivates, relative plant mass (RPM), mean mass indices (MMT, MMO) and the distribution ratio (d).The results correspond with comparable studies on this topic: the highest macrophytes species diversity occurred in Separated Arms. On the contrary, macrophytes had the lowest richness in the Danube River main channel, although their diversity was slightly higher in heavily man-modified water bodies (such as the hydropower plant's reservoir and the abandoned main channel of the so-called Old Danube). Our results suggest that the lateral connectivity types of the river water bodies, primarily characterised by different hydrologic dynamics and human impact expressed as land-use types are responsible for the variability of aquatic macrophyte assemblages along the Danube corridor in Slovakia.

“…Despite that, we can highlight the main transformation processes in the diversity and relative abundance of plant species on the basis of data provided by Bianchini et al (1974), Wiegleb (1983, Borsani et al (2000), Ludovisi et al (2004), Bolpagni (2005, unpublished data) and this work. These data allowed for a general diachronic comparison of the hydrophytic contingent in the study area over the last 35 years, namely in the period of the major changes of the trophic status of Lake Garda as highlighted by Salmaso (2005Salmaso ( , 2010 and Salmaso, and Mosello (2010).…”

“…Most macrophyte studies are outdated or related to specific lake areas (Bianchini et al 1974; Autorità di Bacino del Fiume Po 2000; Ludovisi et al 2004); a recent study however, related the optical characteristics of the lake bottom with the presence/absence and degree of macrophyte coverage using remote sensing (Fazioli 2006). For fish fauna only data provided by fishermen are available.…”
