Data accompanying Polyphenisms and polymorphisms: genetic variation in plasticity and color variation within and among bluefin killifish populations
<p>The presence of stable color polymorphisms within populations begs the question of how genetic variation is maintained. Consistent variation among populations in coloration, especially when correlated with environmental variation, raises questions about whether environmental conditions affect either the fulcrum of those balanced polymorphisms, the plastic expression of coloration, or both. Color patterns in male bluefin killifish provoke both types of questions. Red and yellow morphs are common in all populations. Blue males are more common in tannin-stained swamps relative to clear springs. Here we combined crosses with a manipulation of light to explore how genetic variation and phenotypic plasticity shape these patterns. We found that the variation in coloration is attributable mainly to two axes of variation: (1) a red-yellow axis with yellow being dominant to red, and (2) a blue axis that can override red-yellow and is controlled by genetics, phenotypic plasticity, and genetic variation for phenotypic plasticity. The variation among populations in plasticity suggests it is adaptive in some populations but not others. The variation among sires in plasticity within the swamp population suggests balancing selection may be acting not only on the red-yellow polymorphism but also on plasticity for blue coloration.</p>

Gene expression in male and female sticklebacks from populations with convergent and divergent throat coloration
<p class="MsoNormal">Understanding of genetic mechanisms underlying variation in sexual dichromatism remains limited, especially for carotenoid-based colors. We addressed this knowledge gap in a gene expression study with threespine stickleback. We compared male and female throat tissues across five populations, including two in which female red coloration has evolved convergently. We found that the expression of individual genes, gene ontologies, and coexpression networks associated with red female color within a population differed between California and British Columbia populations, suggesting differences in underlying mechanisms. Comparing females from each of these populations to females from populations dominated by dull females, we again found extensive expression differences. For each population, genes and networks associated with female red color showed the same patterns for males only inconsistently. The functional roles of genes showing correlated expression with female color are unclear within populations, whereas genes highlighted through inter-population comparisons include some previously suggested to function in carotenoid pathways. Among these, the most consistent patterns involved <em>TTC39B</em> (Tetratricopeptide Repeat Domain 39B), which is within a known red coloration QTL in stickleback and implicated in red coloration in other taxa.</p>
Optimizing parametric factors in CIELAB and CIEDE2000 color-difference formulas for 3D printed spherical objects
<p>Forty-five spherical samples were printed using a Stratasys J750 3D color printer, and 82 pairs of 3D samples were produced to investigate the human color perception of the lightness, chroma and hue differences of 3D spherical objects, and to optimize the current CIELAB and CIEDE2000 color-difference formulas. This file contains the CIELAB values of the 45 spherical samples and the calculated colour differences as well as visual colour-difference data of 82 pairs of 3D samples. Optimizations of parametric factors in CIELAB and CIEDE2000 colour-difference formulas were performed based on the colour-difference data provided.</p>
Hummingbird Plumage Color Diversity Exceeds the Gamut of all other Birds
<p>A color gamut quantitatively describes the diversity of a taxon's integumentary coloration as seen by a specific organismal visual system. We estimated the plumage color gamut of hummingbirds (Trochilidae), a family known for its diverse barbule structural coloration, using a tetrahedral avian color stimulus space and spectra from a taxonomically diverse sample of 114 species. The spectra sampled occupied 34.2% of the total diversity of colors perceivable by hummingbirds, which suggests constraints on their plumage color production. However, the size of the hummingbird color gamut is equivalent or greater than the previous estimate of the gamut for all birds, making hummingbirds the most diversely colored family of birds known. Using one model of avian visual systems, our new data for hummingbirds increases the avian color gamut by 56%. Our results demonstrate that barbule structural color is the most versatile plumage coloration mechanism, achieving unique highly saturated colors with multi-peak reflectance.</p>

Black and orange coloration predict success during male-male competition in the guppy
<p>Investigating how both intrasexual competition and intersexual mate choice act within a single system is crucial to understanding the maintenance and diversity of sexually-dimorphic traits. These two processes can act in concert by selecting for the same trait, or in opposition by selecting for different extremes of the same trait; they can also act on different traits, potentially increasing overall trait complexity. We asked whether male-male competition and female mate choice act on the same male traits using Trinidadian guppies, which exhibit complex male-limited color patterns and sexual size dimorphism. We used behavioral assays to assess the relationship between color and male competitive success and then compared our results to the plethora of data on female choice and male color in our study population. We found that males initiated more contests if they were larger than their competitor. Males won contests more often if they had more black coloration than their competitor, and the effect of black was stronger when the male had less orange than his competitor. Additionally, males won more often if they had either more structural color (iridescence) and more orange, or less structural color and less orange than their competitor, suggesting multiple combinations of color traits predict success. Females from our study population exhibit strong preferences for orange coloration. Thus, traits favored in male contests differ from those favored by intersexual selection in this population. Our results suggest that mate choice and male-male competition together promote increased color pattern complexity in this species.</p>
