...This whitefish morph has not been identified in other large watercourses within the region per se (but see: Siwertsson et al. 2010)....

...However, whether the gill raker trait in natural populations of European whitefish is subjected to divergent natural selection, as hypothesized in several recent ecological studies (e.g., Østbye et al. 2005b; Harrod et al. 2010; Siwertsson et al. 2010) has yet to be illuminated in more detail....

...LSR whitefish are larger in size with silvery sides, dark back, and fins, and robust gill rakers with intermediate length and spacing, whereas the DR whitefish is usually smaller sized, darker colored than LSR whitefish, has pointed head shape and has the largest number of long, thin, and densely packed gill rakers (Harrod et al. 2010; Siwertsson et al. 2010)....

...In northern Fennoscandia, whitefish have diverged into distinct morphs adapted to the three principal habitats, such as the littoral, pelagic, and profundal (Kahilainen and Østbye 2006; Harrod et al. 2010; Siwertsson et al. 2010)....

...This is important because resource-driven divergence can depend on prey community structure (Hirsch, Eklöv, & Svanbäck, 2013b), primary production (Siwertsson et al., 2010; Woods et al., 2012b) and the visual environment (Bartels et al....

...MacColl, 2011), they show that a range of biotic and abiotic agents of selection (and their interactions) are associated with phenotypic divergence (Robinson & Wilson, 1994; Smith & Skúlason, 1996; Robinson & Schluter, 2000; Knudsen, Amundsen, & Klemetsen, 2003; Siwertsson et al., 2010; Bartels et al., 2012; Keller & Seehausen, 2012; Woods et al., 2012a; Franklin et al., 2018)....

...Three morphs of whitefish are found in some Finnish and Norwegian lakes (Siwertsson et al., 2010) and one case is known in brown trout from Ireland (Ferguson and Taggart, 1991)....

...Large eyes are also typical for other profundal morphs of Arctic charr (Knudsen et al. 2006; Klemetsen 2010) and European whitefish (Kahilainen and Østbye 2006; Siwertsson et al. 2010) from the same geographical region....

...Age is also a common predictor of species richness in island biogeography, where older islands have had more time to accumulate species both through colonization and within-island speciation (MacArthur and Wilson, 1967; Losos and Schluter, 2000)....

...Lake size is generally a good predictor of inter- and intraspecific fish diversity (Barbour and Brown, 1974; Tonn and Magnuson, 1982; Nosil and Reimchen, 2005), as expected from the widely applicable species–area relationship (MacArthur and Wilson, 1967; Lawton, 1999; Losos and Schluter, 2000)....
