Adolescents’ preferences for sexual dimorphism are influenced by relative exposure to male and female faces [PDF]
, 2009 Exposure to a particular population of faces can increase ratings of the normality and attractiveness of similar-looking faces. Such exposure can also refine the perceived boundaries of that face population, such that other faces are more readily ...

Can diet niche partitioning enhance sexual dimorphism? [PDF]
, 2022 Classic evolutionary theory suggests that sexual dimorphism evolves primarily via sexual and fecundity selection. However, theory and evidence are beginning to accumulate suggesting that resource competition can drive the evolution of sexual dimorphism ...

Variation in sexual dimorphism and assortative mating do not predict genetic divergence in the sexually dimorphic Goodeid fish Girardinichthys multiradiatus [PDF]
, 2012 Sexual dimorphism is often used as a proxy for the intensity of sexual selection in comparative studies of sexual selection and diversification. The Mexican Goodeinae are a group of livebearing freshwater fishes with large variation between species in ...

Filling the gaps in ecology of tropical tiger beetles (Coleoptera: Cicindelidae): first quantitative data of sexual dimorphism in semi-arboreal Therates from the Philippine biodiversity hotspot [PDF]
PeerJBackground Sexual dimorphism, driven by sexual selection, leads to varied morphological distinctions in male and female insects, providing insights into selection pressures across species. However, research on the morphometric variability within specific

Sexual dimorphism in Ramapithecinae [PDF]
Proceedings of the National Academy of Sciences, 1982 The Ramapithecinae are an extinct, mainly Miocene group of hominoids comprising the genera Sivapithecus and Gigantopithecus. Ouranopithecus and Ramapithecus are other included genera, here regarded as invalid ...

Sexual Dimorphism of the Second Cervical Vertebra in Humans [PDF]
, 2023 The pelvis and skull are frequently examined for the expression of sex-linked traits as are the humeral and femoral head dimensions. The second vertebra allows for rotation of the head, which is larger in males than in females.

Sexual dimorphism in the South American water snake Helicops polylepis (Serpentes: Dipsadidae)
Phyllomedusa: Journal of Herpetology, 2021 Sexual selection, fecundity selection and ecological divergence have been the main explanations proposed for the origin and maintenance of sexual dimorphism.

Sexual dimorphism in chronic respiratory diseases
Cell & Bioscience, 2023 Sex differences in susceptibility, severity, and progression are prevalent for various diseases in multiple organ systems. This phenomenon is particularly apparent in respiratory diseases. Asthma demonstrates an age-dependent pattern of sexual dimorphism.

Can sexual selection drive female life histories? A comparative study on Galliform birds [PDF]
, 2007 Sexual selection has been identified as a major evolutionary force shaping male life history traits but its impact on female life history evolution is less clear.
