Avoiding Infanticide In male dominated hierarchies, newly dominant males will sometimes kill resident infants. In lab studies in mice conducted in the 1950s, Hilda Bruce showed that females introduced to an unfamiliar male will terminate their pregnancies, a process subsequently referred to as a Bruce Effect. Roberts et al. (p. 1222, published online 23 February) followed multiple dominance transitions within wild gelada baboons and showed that live birthrate among females previously identified…

The Bruce effect revisited: is pregnancy termination in female rodents an adaptation to ensure breeding success after male turnover in low densities?
- BiologyOecologia
- 2017
It is shown that overwintered and primiparous females, the most abundant cohort during population lows in the increase phase of cyclic rodent populations, were more likely to delay births after turnover of the male than year-born and multiparous Female.
Infant survival in western lowland gorillas after voluntary dispersal by pregnant females
- BiologyPrimates
- 2020
These observations are the first to show that wild female western lowland gorillas can transfer voluntarily while pregnant without incurring infanticide by a new silverback, and highlight the behavioural plasticity shown by female gorillas in response to sexual coercion by males.
Contrasting effects of male immigration and rainfall on rank-related patterns of miscarriage in female olive baboons.
- BiologyScientific reports
- 2021
Using 30 years of data on wild olive baboons in Gombe National Park, Tanzania, there is evidence that rapidly-rising immigrant males induced miscarriages in high-ranking females outside of drought conditions, but miscarriage rates were largely reversed during prolonged periods of low rainfall, suggesting that low- ranking females are particularly vulnerable to low food availability and social instability.

Spontaneous abortion as a response to reproductive conflict in the banded mongoose

The results suggest that abortion may be a means by which disadvantaged females conserve resources for future breeding attempts in more benign conditions, and highlight that female reproductive competition may be resolved long before the production of offspring.
Exposure to a novel male during late pregnancy influences subsequent growth of offspring during lactation
- Biology, PsychologyJournal of evolutionary biology
- 2013
It is demonstrated that female mice experiencing novel males during late pregnancy also alter their investment in progeny, but in a more subtle manner than previously observed, suggesting that cues of unfamiliar males, and possibly their associated threat of infanticide, can produce more wide‐ranging effects on maternal investment than previously recognized.

Infant loss during and after male replacement in gibbons

A review of takeover‐related infant loss in gibbons confirms that periods of male instability are risky for unweaned infants and that replacing males benefit from infant loss.
Data quality and the comparative method: the case of pregnancy failure in rodents
- BiologyJournal of Mammalogy
- 2019
This work compiled data on the Bruce effect, infanticide, and paternal care from one particularly rich source of information, rodents, but found the data set to be less rich than expected and found no clear relationship among the traits.

Infant mortality following male takeovers in wild geladas
- Biology, PsychologyAmerican journal of primatology
- 2008
Results suggest that sexually selected infanticide in geladas may, indeed, be a threat to females with dependent infants and raise the possibility that anecdotal reports of pregnancy termination, accelerated weaning, and deceptive sexual swellings may represent female counterstrategies to male infanticides in gelada.
Exposure to strange adults does not cause pregnancy disruption or infanticide in the gray-tailed vole
- BiologyBehavioral Ecology and Sociobiology
- 1999
It is concluded that neither the Bruce effect nor infanticide occurred differentially as a consequence of the treatments in gray-tailed voles, and field verification is recommended for other species of murid rodents that exhibit theBruce effect before the results are applied to evolutionary theory.
Induced abortion and social factors in wild horses

Evidence is presented that, rather than killing infants directly, invading males induce abortions in females unprotected by their resident stallions and these females are then inseminated by the new males.

Differences between treatment and control populations provide minimal support for the Bruce effect when compared with results from laboratory studies, and are more similar to those of the field study of the gray-tailed vole than predicted.

The Bruce effect may be an adaptive response to infanticide risk in polygynous populations, although studies of free-living populations would be important to confirm the findings.
Abortion following the immigration of an adult male baboon (Papio cynocephalus)

Three abortions and the death of a vigorous infant occurred in a baboon group in Amboseli National Park, Kenya, within the two weeks following the immigration of an aggressive adult male.
Changes in the Reproductive Condition of Female Gelada Baboons Following the Takeover of One-Male Units

It is suggested that females probably balance the cost of wasting the investment in an offspring against the risks of failing to bond with the new male, and come into oestrus even though infanticide does not occur.

There were strong seasonal effects on birth and mortality, with the majority of conceptions occurring during the period of highest rainfall, and there were few rank-related differences in estimated female lifetime reproductive success.

It is argued that the observed enhancement of sexual activity was not imposed by the males' aggressive behaviour but rather was a spontaneous female response to male novelty, which was potent enough to override the role that nutrition and lactation normally play in the control of the females' reproductive activity.
The ecology of conception and pregnancy failure in wild baboons
- Environmental Science

Analysis of female reproductive cycles from multiple baboon groups in the Amboseli basin between 1976 and 2004 indicates that in a highly variable environment, baboon reproductive success is mediated by the interaction between proximate ecological conditions and individual demographic factors.
