Barriers and flow as limiting factors in the spread of an invasive crayfish (Procambarus clarkii) in southern California streams (2005, background): “Light (2003) found that signal crayfish (Pacifastacus leniusculus) abundances declined in years following floods in tributaries of Lake Tahoe (Placer County, California), and that more crayfish were found in lower gradient streams.”
Movement, dispersal and refuge use of co-occurring introduced and native crayfish (2006, background): “Whilst various studies have investigated the spatial behaviour of white-clawed and signal crayfish (Guan & Wiles, 1997; Gherardi, Barbaresi & Villanelli, 1998; Robinson, Lucas & Thom, 2000; Bubb, Lucas & Thom, 2002; Light, 2003; Bubb, Thom & Lucas, 2004), previous studies have been restricted to sin”
