We used isotopic (heavy) labelling to delineate between female and male proteins interacting in the female reproductive tract. Here, we test the efficiency of the labelling protocols on the whole body of males and females.
Reproductive traits that influence female remating and competitive fertilization rapidly evolve in response to sexual selection and sexual conflict. One such trait, observed across diverse animal taxa, is the formation of a structural plug inside the female reproductive tract, either during or short...
Oocyte composition can directly influence offspring fitness, particularly in oviparous species such as most insects, where it is the primary form of parental investment. Oocyte production is also energetically costly, dependent on female condition and responsive to external cues. We investigated whe...
