• Crying wolf, crying foul, or crying shame: alien salmonids and a biodiversity crisis in the southern cool-temperate galaxioid fishes? (2006, background): “In particular, several studies are informative of a long-held view that galaxiids and trout have complementary distributions—that where trout, especially brown trout, invade streams, galaxiids tend to decline or disappear (McDowall 1968c, 2003b).”
• Impact on indigenous species biodiversity caused by the globalisation of alien recreational freshwater fisheries (2003, background): “Behavioural and dietary interactions, between alien and indigenous species, must be understood (McDowall, 2003).”
• Biotic indirect effects: a neglected concept in invasion biology (2006, background): “…species No +ve Nyström et al. (2001) TC P-H and P-P Salmo trutta (brown trout) Native invertebrate species Periphyton species No +ve Flecker & Townsend (1994, 1996); McDowall (2003) Crayfish reduce biomass of grazing snails resulting in increase in periphyton biomass (Nyström et al., 2001).”
• Trout Piscivory in the Colorado River, Grand Canyon: Effects of Turbidity, Temperature, and Fish Prey Availability (2011, background): “Although brown trout are more widely recognized as piscivores, both of these salmonids can pose a predatory threat to native fishes (eg, Crowl et al. 1992 ; McDowall 2003 ); however, relatively few studies have actually quantified the incidence of piscivory by these species or the potential effect”
• Distribution of introduced and native fish in Patagonia (Argentina): patterns and changes in fish assemblages (2008, background): “Fish introductions (Welcomme 1988; Cambray 2003) are frequent and usually elicit changes in the trophic web (McDowall 2003; Reissig et al. 2006), predation on amphibians (Fox et al.”
• The distribution of South American galaxiid fishes: the role of biological traits and post‐glacial history (2004, methodology): “This information is complemented by Jenyns (1842), González Regalado (1945), Oliveros & Cordiviola de Yuan (1974), Campos (1985), Torres et al.

• Hydrological disturbance benefits a native fish at the expense of an exotic fish. (2005, background): “The introduction of brown trout in 1864 to Australia and in 1867 to New Zealand coincided with declines and local extirpations of native galaxiid species through predation by trout (Townsend & Crowl 1991; Closs & Lake 1996) and competitive displacement (reviewed by McDowall 1968, 2003; Crowl, Town”
• Aquaculture, non‐native salmonid invasions and associated declines of native fishes in Northern Patagonian lakes (2009, background): “…decline of many native salmon populations in the northern hemisphere (Fleming et al., 2000; Volpe, Anholt & Glickman, 2001), and salmonid invaders have also caused negative effects on native fishes in the southern hemisphere (McIntosh, Townsend & Crowl, 1992; Ault & White, 1994; McDowall, 2003).”

• Chinook salmon invade southern South America (2008, background): “They are thought to reduce taxonomic diversity (McDowall 2003; Bosch et al. 2006; Dextrase and Mandrak 2006; Ortubay et al. 2006) disrupt native food webs (Townsend 2003; Baxter et al. 2004; Ortubay et al. 2006), modify the cycling of nutrients (Bilby et al. 1996), alter the transmission of…”
