Invasion by the amphipod Gammarus pulex alters community composition of native freshwater macroinvertebrates (2006, background): “However, linking individual species to ecosystem functioning is confounded by abiotic factors and practicalities of removing species assemblages from systems and measuring effects (Townsend, 2003).”
Biodiversity, ecosystem functioning and food webs in fresh waters: assembling the jigsaw puzzle (2009, background): “Large predatory fishes, for instance, can induce powerful cascading effects on ecosystem processes at the lower trophic levels in fresh waters (e.g. Power, 1990; Jones & Sayer, 2003; Townsend, 2003).”
Chinook salmon invade southern South America (2008, background): “…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 diseases…”
Invasion of stream fishes into low trophic positions (2007, background): “In particular, there is a growing body of literature that describes the consequences of alien invasions on ecosystems (e.g., Townsend 2003) and characteristics of invaders that successfully colonize foreign habitats (e.g., Fausch et al. 2001; Kolar & Lodge 2001, 2002; Fisher & Owens 2004; Jeschke &…”
Chapter 5 - Food Web Structure and Stability in 20 Streams Across a Wide pH Gradient (2010, background): “Since the patterning and strength of interactions within a network are both important for its stability, this might explain why strong trophic cascades have been reported in systems where both fish and algae are abundant (e.g. Jones and Sayer, 2003; Power, 1990; Townsend, 2003), whereas this phenome”
Crying wolf, crying foul, or crying shame: alien salmonids and a biodiversity crisis in the southern cool-temperate galaxioid fishes? (2006, background): “ultimately production of food available for fish predators (McDowall 2003b; Townsend 2003); and”
Molecular genetic tools for environmental monitoring of New Zealand's aquatic habitats, past, present and the future (2013, background): “…range from minor effects, as in the case of the sailfin molly (Poecilia latipinna) with its limited distribution to geothermal areas around the southern end of Lake Taupō (McDowall 1990), through to major adverse effects, such as reduced diversity of native fish and zooplankton (Townsend 2003).”
The impact of trout on galaxiid fishes in New Zealand (2010, background): “Although we incorporate knowledge from prior syntheses of trout invasion influences in New Zealand, we refer the interested reader to Crowl et al. (1992), McDowall (2006), and Townsend (2003) for expanded historical, taxon-specific, and ecosystem-level reviews.”
Impacts of freshwater invaders at different levels of ecological organisation, with emphasis on salmonids and ecosystem consequences (2003, background): “channels in New Zealand, Flecker & Townsend (1994) found large invertebrates were relatively rare in the presence of brown trout and insect density and”
Ecological Impacts of Nonnative Freshwater Fishes (2011, background): “for example, in New Zealand streams the impacts of brown trout are well studied at different levels of biological organization (Townsend 2003), including genetic.”
Hydrological disturbance benefits a native fish at the expense of an exotic fish. (2005, background): “Effects of exotic species are well documented and occur from individual to ecosystem level (Mack et al . 2000; Townsend 2003 ).”
Fish fauna destruction after the introduction of a non-native predator (Cichla kelberi) in a Neotropical reservoir (2009, background): “Reservoir support a general trend: non-native predators causing catastrophic consequences on the native biota (Zaret and Paine 1973; Kaufman 1992; Moyle and Light 1996; Gratwicke and Marshall 2001; Townsend 2003; Eby et al. 2006; Macchi et al. 1999).”
Predicting establishment success for introduced freshwater fishes: a role for climate matching (2010, background): “Exotic fish have economic costs and can also have large-scale impacts on ecosystems and are considered a causal factor in the loss of biological diversity and the threatened status of native freshwater fish (Moyle and Light 1996a; Cambray 2003; Townsend 2003; Dextrase and Mandrak 2006; Lovell et al.”
