Human-caused habitat fragmentation can drive rapid divergence of male genitalia

open access: yesEvolutionary Applications, 2014
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]

open access: yesarXiv, 2023
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]

open access: yes, 2017
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.

Genitalic stridulation during copulation in a species of crane fly,Tipula (Bellardina) sp. (Diptera: Tipulidae)

open access: yesRevista de Biología Tropical, 2009
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.
