Strength of sexual selection and sex roles vary between social groups in a coral reef cardinalfish
<p>The strength and direction of sexual selection can vary among populations. However, spatial variability is rarely explored at the level of the social group. Here we investigate sexual selection and sex roles in the paternally mouthbrooding, socially monogamous, and site-attached pajama cardinalfish, <em>Sphaeramia nematoptera</em>. Females were larger, more aggressive, and had a longer dorsal fin filament, indicating reversed sex roles. At the scale of social groups, we show the Bateman gradient and reproductive variance depending on the sex ratio and size of the groups. In small and medium-sized groups with balanced or male-biased sex ratios, Bateman gradients were steeper for females, whereas gradients were equally steep for both sexes in large groups or when the sex ratio was female-biased. For both sexes, reproductive variance increased with group size and with a higher male-to-female sex ratio. In <em>S. nematoptera</em>, mating opportunities outside the socially monogamous pair appear to impact sexual selection. We conclude that the strength and direction of sexual selection can be masked by social dynamics in group-living species when considering only population and large-scale demographic processes.</p>

Strength and direction of sexual direction and sex roles vary between social groups in a coral reef cardinalfish
<p><span>The strength and direction of sexual selection can vary among geographically distinct populations, and within populations across time. However, spatial and temporal variability at the level of the social unit is rarely explored. Here we investigate sexual selection and sex roles in the paternally mouthbrooding and site-attached pajama cardinalfish, <em>Sphaeramia nematoptera</em>, where social groups can vary in size and adult sex ratio. We found that reproductive success scaled with mating success for both sexes, consistent with positive sexual selection at population level. However, within social groups, we show that adult sex-ratio and group size can influence the strength and direction of sexual selection. Our results show the Bateman gradient is steeper for females in groups with male-biased adult sex ratios and sex roles are reversed, but steeper for males in female-biased groups, and equally steep when the sex ratio is even. In medium sized groups, reproductive skew was highest for both sexes and males had a steeper Bateman gradient than females, whereas in small and large groups the gradients were equal. We conclude that the strength and direction of sexual selection and sex roles can be masked by social dynamics in group-living species when considering only population and demographic processes.</span></p>
