We have recently described a murine model of vaginal secretion that allows the measurement of minute changes in vaginal secretion. Using this model, we determined that female mice experience a vaginal secretory response to the scent of males, a response regulated by circadian and estrous factors since females did not respond during their sleep phase, nor when in metestrus. Female mice can distinguish the social status of a male by scent cues and show a preference for the scent of dominant males.

Power, especially in the court system, is a potent determinant of intergroup relationships. Blind justice being only an ideal, public opinion can influence whether harm to low power groups is considered criminal and should be prosecuted. Our experiments investigated the impact of social dominance orientation (SDO) on the perceived appropriateness of punishment for harm to subordinate group members by dominant group members.

This paper explores the ethical implications of long-term, transgenerational projects through the lens of neo-republican theory, focusing on the issue of intergenerational domination. Traditional accounts of intergenerational justice often emphasize one-directional influence from present to future generations. This study proposes a threefold generational framework-the current generation (CG), subsequent generations (SGs), and remote generations (RGs)-to better capture the temporal complexity and multi-layered dependencies that define transgenerational projects such as radioactive waste management.

Developmental plasticity, the ability to adapt one's phenotype to environmental cues, is crucial during early-life stages and can affect fitness. Despite significant androgenic variation between females of select species, the impact of maternal hormones on offspring ontogeny in wild mammals has been rarely investigated. Here, we rely on natural and experimentally induced variation in androgen action between dominant and subordinate female meerkats, Suricata suricatta, to examine plasticity of vocal development in their offspring.

Male reproductive success is determined by the interplay of female mate choice and male-male competition, often linked to dominance rank in social animals. Across taxa, elaborate ornaments, such as bright coloration or large antlers, often function as badges of status, signalling male competitive ability to rivals. In species where females mate with multiple males, post-mating sperm competition also plays an important role in male reproductive success and is associated with larger relative testes size.
