Article Synopsis
- The study examined how resource quality and parental care impact sexual and non-sexual traits in a rainforest dung beetle species from Singapore, focusing on how these traits reflect overall condition and mate success.
- Results showed that sexual traits, particularly horn length, varied significantly based on the type of dung used for rearing, with genotypic differences influencing male traits more than female traits.
- Parental provisioning patterns indicated a trade-off between the quality of resources and the quantity provided, suggesting that parents might prioritize early offspring fitness over the quality of dung used, potentially influencing later generation success.
Sexual size dimorphism (SSD) arises when natural selection and sexual selection act differently on males and females. Male-biased SSD is rarer in insects and usually indicates strong sexual selection pressure on male body size in a species. Patterns of SSD can also vary between populations of species that are exposed to different environmental conditions, such as differing resource availability and diversity.
