• Hydrological disturbance benefits a native fish at the expense of an exotic fish. (2005, background): “The strongest evidence of the effects of introduced brown trout on native galaxiids in stream ecosystems is provided by their non-overlapping distributions (Crowl, Townsend & McIntosh 1992; Closs & Lake 1996; McIntosh 2000 ).”
• Strategies for conserving native salmonid populations at risk from nonnative fish invasions: tradeoffs in using barriers to upstream movement (2006, background): “Townsend and Crowl (1991) and McIntosh (2000) reported strong negative correlations between brown trout and native galaxiid abundance in stream segments below barriers throughout two New Zealand watersheds, and provided experimental evidence that predation by large brown trout was the cause.”
• Crying wolf, crying foul, or crying shame: alien salmonids and a biodiversity crisis in the southern cool-temperate galaxioid fishes? (2006, background): “Biotic characteristics that McIntosh (2000a) thought likely to better adapt galaxiids than trout to unstable streams included: (1) Small size; (2) Relatively slim, tubular body shape; (3) Negative buoyancy; (4) Benthic behaviour; (5) Lower food requirements; and (6) An ability to burrow into…”
• The impact of trout on galaxiid fishes in New Zealand (2010, background): “Similarly, stream disturbance limits trout but not galaxiid distributions in the upper Waimakariri River, and thus creates predator-free refugia for galaxiids in an otherwise trout-dominated landscape (McIntosh 2000a).”
• Alien invasions in aquatic ecosystems: Toward an understanding of brook trout invasions and potential impacts on inland cutthroat trout in western North America (2002, unknown): “Simpler measures of the apparent impacts of nonnative species may still be useful (e.g., distribution patterns; Dunham et al., 1999; McIntosh, 2000).”
• The distribution of South American galaxiid fishes: the role of biological traits and post‐glacial history (2004, background): “A vision well adapted to darkness is common in Galaxiidae (Ali et al., 1990) as well as nocturnal habits (Kusabs & Swales, 1991; Glova et al., 1992; McIntosh et al., 1992, 1994; Ault & White, 1994; McIntosh, 2000).”
• Impacts of Introduced Salmonids on Native Galaxiids in New Zealand Upland Streams: A New Look at an Old Problem (2003, background): “McIntosh ( McIntosh and Townsend 1996 , 1998 ; McIntosh 2000a , 2000b ) compared the behavior of invertebrates in the presence of a native galaxiid predator with their behavior in the presence of brown trout (a novel, introduced predator) in both experimental channels and natural streams.”
• Changes in the distribution of native fishes in response to introduced species and other anthropogenic effects (2010, background): “Salmonids have been introduced into cool temperate waters world-wide, and negative effects on native fish, especially on galaxiids, have been reported or inferred in virtually all locations (McDowall, 2006), but especially in New Zealand (Townsend & Crowl, 1991; Flecker & Townsend, 1994; McIntosh, 2”
• Evaluating Potential Effects of Exotic Freshwater Fish From Incomplete Species Presence–absence Data (2002, background): “Unlike Patagonia, studies in Australasia were largely conducted in rivers, many of them small streams; as in Patagonia, opinions about the extent of the effects that trout have on native fish in New Zealand are contradictory (McIntosh 2000).”
• Impacts of freshwater invaders at different levels of ecological organisation, with emphasis on salmonids and ecosystem consequences (2003, background): “responsible for the fragmented distribution of native fish (Crowl et al., 1992; McIntosh, 2000).”
