“…The recruitment of different tree species depends on the occurrence of bank erosion on floodplains and islands, formation of new, bare alluvial surfaces, and suitable hydrological conditions. Human pressures may therefore lead to either a reduction or expansion of vegetation in rivers [46], eventually producing non-natural equilibrium states [26] that may determine centuries of channel adjustment [6]. These patterns are common in large rivers of Europe [20].…”

“…Such rivers show extremely large spatial variability in sedimentary features and rapid responses to upstream changes, including the construction of check-dams and land cover changes (Brooks and Brierley, 1997;Kondolf et al, 2002;Marston et al, 2003;Liébault et al, 2005;Boix-Fayos et al, 2007;Keesstra, 2007;García-Ruiz and Lana-Renault, 2011;Segura-Beltrán and Sanchis-Ibor, 2013). Torrential rivers, or torrents, are particular types of mountain rivers, with longitudinal gradients >5%, unstable geological formations, and sediment dominated by boulders and blocks that enter the streambed mainly through debris flows and landslides (Rickenmann, 1997;Benda et al, 2005;D'Agostino, 2013;Picco et al, 2014). Torrents are generally short, and can be affected by large variability in discharge and the occurrence of sudden floods with very destructive capacity (White et al, 1997).…”

“…A szigetekkel kapcsolatos vizsgálatok oka, hogy a vízfolyások szerves részét képezik hidrológiai, geomorfológiai, ökológiai, sőt még geopolitikai szempontból is (Wyrick és Klingeman 2011, Picco et al 2014a. A szigetek a természetes állapotban lévő és az antropogén hatások által befolyásolt folyórendszerekben is egyaránt előfordulhatnak.…”

“…Biológiailag is jelentős szerepet tölthetnek be, hiszen izoláltságuk miatt különleges növényeknek és állatoknak nyújthatnak menedékhelyet, így a védett fajok fennmaradását teszik lehetővé (Wyrick és Klingeman 2011). Emellett növelhetik a biodiverzitást és ökológiai folyosóként is funkcionálhatnak (Picco et al 2014a). Az olyan folyószakaszokon ahol szigeteket találunk, sokszínűbb vízi életközösségek fordulnak elő, mint a szigetekkel nem rendelkező szakaszokon (Arscott et al 2000).…”
