“…Our model results supported the prediction by Ens et al (1993) that the reproductive success of initiators of divorce should increase after divorce, and that the success of victims should decrease after divorce.…”

“…In our model, mate change occurred after each breeding season. If, instead, it occurred throughout the year (Ens et al 1993), there may be a cost to the current year's reproductive success due to time spent searching for a new mate or to having to prevent a mate being taken by a competitor. These costs may be higher if the current mate reduces his or her e¡ort in response.…”

“…We investigate divorce strategies using a model in which there are annual decisions after breeding. The model is based on the assumption that individuals divorce their current mate to mate with an individual of higher quality as proposed by the`better option hypothesis' (Rowley 1983;Johnston & Ryder 1987;Ens et al 1993;McNamara & Forslund 1996). Ens et al (1996) review factors that a¡ect the breeding quality of birds.…”

We present a theoretical investigation of divorce. Arguments are couched in terms of birds, but should be applicable to other groups of organisms. We model a population in which there is a range of both male and female qualities, and decisions on whether to divorce are made by both members of a breeding pair. The reproductive success of a pair is additive in male and female qualities in the baseline case, but we also consider the e¡ect of quality interactions. The availability of new mates depends on the divorce strategy of all population members. We allow for the possibility that mate choice is associative in quality, although we do not explicitly model the mate choice process. Using a game-theoretical model which incorporates these factors we investigate the following issues: the form of the evolutionary stable strategy, and the implications of this strategy for quality correlations in breeding pairs and for the distribution of qualities among unpaired individuals; divorce rates, reproductive success and mate quality changes over the lifetime of an individual, and the dependence of these qualtities on the individual's quality; mean population divorce rates and their dependence on costs of divorce, longevity and the extent of quality variation in the two sexes; initiators of divorce and reproductive success before and after divorce.

“…The better option hypothesis states that an individual will decide to divorce their current partner if they can improve their reproductive success by mating with an alternative partner (Ens et al 1993;Choudhury 1995). In this case, the partner who chooses to divorce may increase their reproductive success, but the partner who is deserted may be worse off -especially if they are unable to attract another mate or can only acquire a mate of lower-quality compared to their original mate.…”

Purpose: Serial monogamy is likely an adaptive mating strategy for women when the expected future fitness gains with a different partner are greater than expected future fitness with one's current partner. Methods: Using interview data from over 400 women in San Borja, Bolivia, discrete-time event history analyses and random effects regression analyses are conducted to examine predictors of marital dissolution, separated by remarriage status, and child educational outcomes. Results: Male income is inversely associated with women's risk of 'divorce and remarriage', while female income is positively associated with women's risk of 'divorce, but not remarriage'. Children of women who 'divorce and remarry' tend to have significantly lower educational outcomes than children of married parents, but women with higher incomes are able to buffer their children from the negative educational outcomes of divorce and remarriage. Counter to predictions, there is no evidence that women with kin in the community have a significant difference in likelihood of divorce or a buffering effect of child outcomes. Conclusions: In conclusion, there are different predictors of divorce depending on whether the woman goes on to remarry, suggesting that male income may be a better predictor of a serial monogamy strategy, while female income predicts marital dissolution only. These results suggest that women who are relatively autonomous because of greater income may not benefit from remarriage.

“…infidelity) and/or by divorcing a partner after initial breeding [9][10][11][12]. Consequently, when the social environment influences initial mate choice by determining the number of opposite sex associates [13,14], it should also influence the emergence of secondary mating strategies. In this way, the social environment may not only impact breeding success through the immediate effects of the quality of the social partnership, but also through later fitness effects of secondary mating strategies.…”

Carry-over effects of the social environment on future divorce probability in a wild bird population

ResearchCite this article: Culina A, Hinde CA, Sheldon BC. 2015 Carry-over effects of the social environment on future divorce probability in a wild bird population. Proc. R. Soc. Initial mate choice and re-mating strategies (infidelity and divorce) influence individual fitness. Both of these should be influenced by the social environment, which determines the number and availability of potential partners. While most studies looking at this relationship take a population-level approach, individual-level responses to variation in the social environment remain largely unstudied. Here, we explore carry-over effects on future mating decisions of the social environment in which the initial mating decision occurred. Using detailed data on the winter social networks of great tits, we tested whether the probability of subsequent divorce, a year later, could be predicted by measures of the social environment at the time of pairing. We found that males that had a lower proportion of female associates, and whose partner ranked lower among these, as well as inexperienced breeders, were more likely to divorce after breeding. We found no evidence that a female's social environment influenced the probability of divorce. Our findings highlight the importance of the social environment that individuals experience during initial pair formation on later pairing outcomes, and demonstrate that such effects can be delayed. Exploring these extended effects of the social environment can yield valuable insights into processes and selective pressures acting upon the mating strategies that individuals adopt.
