Divergent preference functions generate directional selection in a jumping spider

open access: yesScientific Reports, 2023
Sexual selection has long been thought to promote speciation, but this possibility still remains a topic of controversy. Many theoretical models have been developed to understand the relationship between sexual selection and speciation, but such ...

Phenology of scramble polygyny in a wild population of chrysomelid beetles: the opportunity for and the strength of sexual selection [corrected]. [PDF]

open access: yesPLoS ONE, 2012
Recent debate has highlighted the importance of estimating both the strength of sexual selection on phenotypic traits, and the opportunity for sexual selection.

Metapopulation structure modulates sexual antagonism

open access: yesEvolution Letters, 2021
Despite the far‐reaching evolutionary implications of sexual conflict, the effects of metapopulation structure, when populations are subdivided into several demes connected to some degree by migration, on sexual conflict dynamics are unknown.

Sexual selection on song and cuticular hydrocarbons in two distinct populations of Drosophila montana [PDF]

open access: yes, 2011
Sexual selection has the potential to contribute to population divergence and speciation. Most studies of sexual selection in Drosophila have concentrated on a single signaling modality, usually either courtship song or cuticular hydrocarbons (CHCs ...

Sexual Selection and Proteinaceous Diversity in the Femoral Gland Secretions of Lacertid Lizards

open access: yesDiversity, 2023
Sexual selection contributes to the diversity of chemical signals in various animal groups. Lizards are good model species to study how sexual selection shapes signal diversity, as they are a chemically oriented taxonomic group with different levels of ...

Can sexual selection drive female life histories? A comparative study on Galliform birds [PDF]

open access: yes, 2007
Sexual selection is an important driver of many of the most spectacular morphological traits that we find in the animal kingdom (for example see Andersson, 1994). As such, sexual selection is most often emphasized as

Timing as a sexually selected trait: the right mate at the right moment [PDF]

open access: yes, 2017
Sexual selection favours the expression of traits in one sex that attract members of the opposite sex for mating. The nature of sexually selected traits such as vocalization, colour and ornamentation, their fitness benefits as well as their costs have ...

Sexual selection for males with beneficial mutations

open access: yesScientific Reports, 2022
Sexual selection is the process by which traits providing a mating advantage are favoured. Theoretical treatments of the evolution of sex by sexual selection propose that it operates by reducing the load of deleterious mutations.

Are Hand Preference and Sexual Orientation Possible Predicting Factors for Finasteride Adverse Effects in Male Androgenic Alopecia? [PDF]

open access: yes, 2016
Sexual side effects of finasteride seem to be redoubtable, being encountered not only during therapy but also after treatment cessation. Consequently, any possible clinical/paraclinical elements that might predict these adverse effects would be useful in
