Female reproductive ageing persists despite high infanticide risk in chacma baboons and geladas.

Across mammals, fertility and offspring survival are often lowest at the beginning and end of females' reproductive careers. However, extrinsic drivers of reproductive success-including infanticide by males-could stochastically obscure these expected age-related trends. Here, we modelled reproductive ageing trajectories in two cercopithecine primates that experience high rates of male infanticide: the chacma baboon () and the gelada ().

While female capital offences have repeatedly caused a stir since the beginning of the modern era at the latest, female violent crime has remained a marginal phenomenon in statistical observations for a long time. Forensics, with its traditional core disciplines of psychiatry and law, also remained focused on the dangerous male perpetrator for a long time in its analysis and theory development beyond infanticide: male forensic scientists analysed male perpetrators of violence.Since the 1960s, there has been an increasing number of scientific contributions on female criminality and its causes in West Germany.

Adoption among nonhuman primates (hereafter primates) has been widely reported, particularly in chimpanzees, renowned for their higher intelligence and well-developed cognition. In contrast to adoption in other Old World monkeys, this case of adoption in golden snub-nosed monkeys () involves two infants associated with three units characterized by distinct social structures and reproductive functions. Consequently, this case extends beyond traditional hypotheses on allomaternal care and adoption-such as enhancing the fitness of adoptive mothers, fostering maternal behaviors, and improving fitness through social and individual interactions-to necessitate an association with the complex social structure characterized by hierarchical, multilevel composition, akin to human society, and intense sexual selection that frequently results in infanticide.

Infanticide is widespread across the animal kingdom, but the physiological drivers of infanticide versus care or neglect are relatively unexplored. Here, we identified salient environmental and physiological antecedents of infanticide in the mimic poison frog (Ranitomeya imitator), a biparental amphibian. We explored potential environmental cues influencing infant-directed behavior by evaluating changes in the frequency of food provisioning and tadpole mortality after either cross-fostering tadpoles between family units or displacing tadpoles within the terraria of their parents.

Article Synopsis
- Male investment in infant care among polygynandrous primates is linked to factors like offspring survival, social status, and future mating opportunities, with varied relationships observed in white-faced capuchins.
- Genetic paternity analysis and behavioral observations revealed that overall male-female affiliation increased after the birth of an infant, with a notable bias towards male infants in terms of increased contact and proximity.
- The results suggest that male capuchins may not recognize their own offspring, indicating a potential sex-specific socialization trend that fosters long-term male cooperation in this species.
