Data from: The neurodevelopmental genes alan shepard and Neuroglian contribute to female mate preference in African Drosophila melanogaster
<p>Mate choice is a key trait that determines fitness for most sexually reproducing organisms, with females often being the choosy sex. Female preference often results in strong selection on male traits that can drive rapid divergence of traits and preferences between lineages, leading to reproductive isolation. Despite this fundamental property of female mate choice, very few loci have been identified that contribute to mate choice and reproductive isolation. We used a combination of population genetics, quantitative complementation tests, and behavioral assays to demonstrate that alan shepard and Neuroglian contribute to female mate choice, and could contribute to partial reproductive isolation between populations of Drosophila melanogaster. Our study is among the first to identify genes that contribute to female mate preference in this historically important system, where female preference is an active premating barrier to reproduction. The identification of loci that are primarily known for their roles in neurodevelopment provides intriguing questions of how female mate preference evolves in populations via changes in sensory system and higher learning brain centers.</p>
Colorful traits in female birds relate to individual condition, reproductive performance, and male mate preferences: A meta-analytic approach dataset
<p>Colorful traits in females are suggested to have evolved and be maintained by sexual selection. Although several studies have evaluated this idea, support is still equivocal. <span><span>Evidence has been compiled in reviews, and a handful of quantitative synthesis have explored evidence of the link between condition and specific color traits in males and females. However, understanding the potential function of females' colorful traits in sexual communication has not been the primary focus of any of those previous studies</span></span><span>. </span>Here, using a meta-analytic approach, we find that evidence from empirical studies in birds supports the idea that colorful female ornaments are positively associated with residual mass and immune response, clutch size, and male-mate preferences. Hence, colorful traits in female birds likely evolved and are maintained by sexual selection.</p>

Female great tits (Parus major) reproduce earlier when paired with a male they prefer
<p><span>Mate choice is a key component of reproductive biology. Females often prefer certain males but do females modulate their reproductive investment depending on whether they are mated with their preferred partner? We investigated this question in great tits (<em>Parus</em> <em>major</em>) where we subjected 36 females to a six-choice mate preference test. Male morphological traits and the female's own characteristics did not influence the preference females expressed. We did find that females spent significantly more time near more exploratory males. We then paired them with one of the males in aviaries and subsequently monitored their reproductive investment (through measurement of plasma 17β-oestradiol concentrations, first egg date, clutch size, and egg size). Females that were mated with a male for which they had a strong preference laid their first clutch significantly earlier in the season than females paired with a male they less preferred. Our results show that mate preference influences reproductive investment in great tits, thereby linking mate choice to bird reproductive decisions. </span></p>
Data from: Variation in the strength of female mate preference for male size supports the signal reliability hypothesis
<p>Both sexually selected traits and mate preferences for these traits can be condition dependent, yet how variation in preferred traits could select for condition dependent preferences has rarely been examined. The signal reliability hypothesis predicts that mate preferences vary across environments in relation to the reliability of the information preferred traits provide in those environments. Extensive variation in copy number of the <em>mc4r</em> gene on Y chromosome is correlated with adult male size in <em>Xiphophorus multilineatus</em>, when males stop growing. This genetic variation allowed us to use a split-sibling design to show that male size is more variable, and thus likely to provide reliable information about male genotype, when males were reared in a warm as compared to cold environment. Females reared in the warm environment had stronger mate preferences for male size. Understanding how the reliability of male traits can select for conditional variation in the strength of the female mate preferences will further our discovery of adaptive mate preferences. For example, the relationship between the strength of a female's mate preference and their growth rates supports previous work hypothesizing disassortative mating in relation to growth rates to mitigate a documented growth-mortality tradeoff in this species.</p>
