“…Similar spawning color selection would likely affect males and females differently because males have no alternative use for their carotenoids while females must partition their carotenoids between themselves and their young (Craig and Foote 2001;Foote et al 2004;Nordeide et al 2006). Our data are consistent with this apparent trade-off between body and egg color in female sockeye salmon (Crozier 1970;Craig and Foote 2001;Foote et al 2004).…”

“…It is also important to provision eggs with carotenoids to improve the immune response and survival of young (Blount et al 2000(Blount et al , 2002Tyndale et al 2008). Many organisms concentrate carotenoids in their eggs at the expense of their own body color and, potentially, effective immune response (Green 1965;Skarstein and Folstad 1996;Royle et al 2003;Nordeide et al 2006;Baeta et al 2008).…”

Salmonids spawn in highly diverse habitats, exhibit strong genetic population structuring, and can quickly colonize newly created habitats with few founders. Spawning traits often differ among populations, but it is largely unknown if these differences are adaptive or due to genetic drift. To test if sockeye salmon (Oncorhynchus nerka) populations are adapted to glacial, beach, and tributary spawning habitats, we examined variation in heritable phenotypic traits associated with spawning in 13 populations of wild sockeye salmon in Lake Clark, Alaska. These populations were commonly founded between 100 and 400 hundred sockeye salmon generations ago and exhibit low genetic divergence at 11 microsatellite loci (F ST \ 0.024) that is uncorrelated with spawning habitat type. We found that mean P ST (phenotypic divergence among populations) exceeded neutral F ST for most phenotypic traits measured, indicating that phenotypic differences among populations could not be explained by genetic drift alone. Phenotypic divergence among populations was associated with spawning habitat differences, but not with neutral genetic divergence. For example, female body color was lighter and egg color was darker in glacial than non-glacial habitats. This may be due to reduced sexual selection for red spawning color in glacial habitats and an apparent trade-off in carotenoid allocation to body and egg color in females. Phenotypic plasticity is an unlikely source of phenotypic differences because Lake Clark sockeye salmon spend nearly all their lives in a common environment. Our data suggest that Lake Clark sockeye salmon populations are adapted to spawning in glacial, beach and tributary habitats and provide the first evidence of a glacial spawning ecotype in salmonids.Glacial spawning habitats are often young (i.e.,\200 years old) and ephemeral. Thus, local adaptation of sockeye salmon to glacial habitats appears to have occurred recently.

“…A possible physiological basis for our finding about the negative relationship between female redness and the early viability of her offspring could be that the development of carotenoid-based breeding coloration in females might reduce the availability of these valuable pigments (antioxidants) to developing embryos, thus leading to lower incubation success per brood (see e.g., Ahmadi et al 2006;Tyndale et al 2008). In support of this idea, Nordeide et al (2006Nordeide et al ( , 2008 found that the intensity of red ornamental coloration in both the stickleback and Arctic charr females may, indeed, be negatively correlated with the amount of carotenoids in the eggs, though the relationship was only marginally significant in the latter case.…”

“…By experimentally controlling for the confounding maternal and environmental effects (Sheldon 2000), it was possible to test whether differently coloured males differ in their genetic quality, determined as their offspring's early survival and growth performance. On the other hand, because maternal effects are known to be pronounced in early developmental phases of fish (see Kamler 2008 and references therein), and because charr females might be constrained to trade-off carotenoids between investment in ornamentation and investment in eggs (Nordeide et al 2006(Nordeide et al , 2008, we also examined whether there are any correlative evidence that the variation in sexual coloration among females (dams) would be related to their reproductive potential.…”

Genetic theories of sexual selection predict that most ornamental secondary sexual traits provide reliable indication of the genetic quality of their bearers. Accordingly, also the offspring of mates with elaborate mating display should perform better than those of less conspicuous counterparts. In this study, we used Arctic charr (Salvelinus alpinus) as a model species to investigate whether the variation in a carotenoid-based red breeding coloration (a sexually dichromatic trait) in different sexes would reflect differences in individual genetic variability, one measure of individual quality, and/or indirectly, be manifested in variation in the offspring's early viability and growth. We created maternal half-sibling families by artificially fertilizing the eggs with milt from bright-and pale-coloured males and then held the resulting progenies under identical hatchery conditions. The expression of red coloration among parental fish was not associated with their genetic diversity estimates in either sex nor did offspring sired by bright males consistently differ in terms of embryo survival or endogenous growth efficiency from offspring sired by pale males. By contrast, maternal effects were notably strong and, additionally, the degree of female coloration was negatively linked to their reproductive potential. The more intensely coloured females had a smaller relative fecundity and they also produced offspring of lower viability, implying a significant trade-off in resource allocation between ornamentation and offspring. Our results indicate that the red breeding ornamentation of Arctic charr is likely to be informative rather among females than males when the reproductive quality is predicted on grounds of the number of offspring produced. Nevertheless, this study does not support the direct selection hypothesis in explaining the evolution of female ornamentation, but rather suggests that the less intense coloration of female charr compared to males may reflect inter-sexual differences in the trade-off between natural and sexual selection.

“…competitive traits : ornaments, armaments, aggression, etc. (Cain & Ketterson, 2012; West-Eberhard, 1983)) is often associated with decreased maternal effort (Bell et al, 2011; Dantzer et al, 2011; Fite et al, 2005; Fitzpatrick et al, 1995; Nordeide et al, 2006; Packer et al, 1995; Rosvall, 2011). …”

Summary When competition for sex-specific resources overlaps in time with offspring production and care, trade-offs can occur. Steroids hormones, particularly testosterone (T), play a crucial role in mediating such trade-offs in males, often increasing competitive behaviors while decreasing paternal behavior. Recent research has shown that females also face such trade-offs; however, we know little about the role of T in mediating female phenotypes in general, and the role of T in mediating trade-offs in females in particular. Here we examine the relationship between individual variation in maternal effort and endogenous T in the dark-eyed junco, a common songbird. Specifically, we measure circulating T before and after a physiological challenge (injection of gonadotropin releasing hormone, GnRH), and determine whether either measure is related to provisioning, brooding, or the amount of T sequestered in egg yolk. We found that females producing more T in response to a challenge spent less time brooding nestlings, but provisioned nestlings more frequently, and deposited more T in their eggs. These findings suggest that, while T is likely important in mediating maternal phenotypes and female life history tradeoffs, the direction of the relationships between T and phenotype may differ from what is generally observed in males, and that high levels of endogenous T are not necessarily as costly as previous work might suggest.
