Women rated the facial attractiveness and masculinity of photographs of 105 healthy and beardless men between 30 and 45 years old, and their ratings were positively correlated with age and testosterone, and negatively correlated with adiposity.

New meta-analysis out on the role of sexual selection in speciation!
Across the Animal kingdom, we found that stronger sexual selection is significantly (though weakly) associated with greater species richness in comparative studies — suggesting a modest role for sexual selection in speciation.
A great collaboration with Tim Janicke, Jeanne Tonnabel, Tamra Mendelson & Mike Ritchie.

Operational sex ratio (Ecology 🏞️)
In the evolutionary biology of sexual reproduction, operational sex ratio is the ratio of sexually competing males that are ready to mate to sexually competing females that are ready to mate, or alternatively the local ratio of fertilizable females to sexually active males at any given time. This differs from physical ...

Male intrasexual competition (Evolutionary biology 🧬)
In ethology, male-male intrasexual competition occurs when two males of the same species compete for the opportunity to mate with a female. Sexually dimorphic traits, size, sex ratio, and the social situation may all play a role in the effects male-male competition has on the reproductive success of a male and the...

Ornamental traits play a central role in sexual selection. Gussone et al. identify sources of phenotypic variation in ornamental traits by showing that inbreeding and genetic relatedness of rivals affect the dynamic colour-expression in competing males in a cichlid fish.

How does sexual selection influence behavioural consistency? Using experimental evolution, Brand et al. demonstrate that evolution under heightened sexual selection limits individual phenotypic plasticity and promotes male behavioural consistency.
