Genital evolution: why are females still understudied? [PDF]
The diversity, variability, and apparent rapid evolution of animal genitalia are a vivid focus of research in evolutionary biology, and studies exploring genitalia have dramatically increased over the past decade. These studies, however, exhibit a strong

Human-caused habitat fragmentation can drive rapid divergence of male genitalia
The aim of this study rests on three premises: (i) humans are altering ecosystems worldwide, (ii) environmental variation often influences the strength and nature of sexual selection, and (iii) sexual selection is largely responsible for rapid and ...

Gender-Segmented Labor Markets and Foreign Demand Shocks [PDF]
Gender segmentation in labor markets shapes the local effects of international trade. We develop a theory that combines exports with gender-segmented labor markets and show that, in this framework, foreign demand shocks may either increase or decrease the female-to-male employment ratio.

Swimming against the tide: Gender bias in the physics classroom [PDF]
This study examines physics students' evaluations of identical, video-recorded lectures performed by female and male actors playing the role of professors. The results indicate that evaluations by male students show statistically significant overall biases with male professors rated more positively than female professors.

The male genitalia of many animal groups have elaborate and species-specific forms. One hypothesis to explain why this is so is that male genitalia function as stimulatory devices that are under sexual selection by cryptic female choice.
