Convergent evolution of SWS2 opsin facilitates adaptive radiation of threespine stickleback into different light environments

Abstract: Repeated adaptation to a new environment often leads to convergent phenotypic changes whose underlying genetic mechanisms are rarely known. Here, we study adaptation of color vision in threespine stickleback during the repeated postglacial colonization of clearwater and blackwater lakes in the Haida Gwaii archipelago. We use whole genomes from 16 clearwater and 12 blackwater populations, and a selection experiment, in which stickleback were transplanted from a blackwater lake into an uninhabited clearwater pon… Show more

“…Recent population genomic studies have begun to unravel the evolutionary forces that underly phenotypic change following the colonization of new habitats Jones, Grabherr, et al, 2012;Marques, Taylor, et al, 2017;Rosenblum et al, 2004). It would be interesting to know whether the phenotypic divergence that we observe in color, shape, size, and plating between freshwater morphs is associated with genetic divergence among populations and color morphs.…”

“…The quest for elucidating the genomic basis of adaptive diversification commonly proceeds by comparing populations from two ecologically distinct habitat types at genome-wide markers. Genetic loci important to differential adaptation are then identified by screening the populations for exceptionally strong habitat-related genetic differentiation relative to the genome-wide background level (e.g., Roesti et al 2015;Lamichhaney et al 2016;Reid et al 2016;Yeaman et al 2016;Marques et al 2017). This approach is particularly informative when multiple populations adapted independently to each habitat type are available, as such "parallel" (or convergent; Arendt and Reznick 2008) evolution helps distinguish deterministic selective from stochastic genetic differentiation (Berner and Salzburger 2015).…”

“…These results were also modulated within lakes by depth, a proxy for optical environment (Bolnick et al 2016;Brock et al, 2017a;Brock, Bolnick, & Cummings, 2017b). Threespine stickleback males display color polymorphism at multiple geographic scales (Reimchen 1989;Boughman, 2001;Scott, 2001;Brock et al, 2017a;Brock, Bolnick, & Cummings, 2017b;Marques, Lucek et al, 2017;Marques, Taylor et al, 2017). As these color phenotypes typically covary with features of the optical environment, sensory drive theory is commonly invoked to explain the maintenance of multiple color phenotypes (Reimchen 1989;Boughman, 2001;Scott, 2001;Brock et al, 2017a;Brock, Bolnick, & Cummings, 2017b;Marques, Lucek et al, 2017;Marques, Taylor et al, 2017).…”

However, negative frequency-dependent selection via male-male competition could also facilitate the maintenance of color polymorphisms, possibly via interactions with the signaling environment (Bolnick et al 2016;Djikstra & Border, 2018;Tinghitella et al, 2017).…”
