Article Synopsis
- When parents reproduce successfully, they are more likely to divorce and seek new mates rather than stay together, contrary to traditional evolutionary expectations.
- Data from plover populations show that successful nesting leads to divorce, while failed nests result in parents sticking together for future breeding.
- Divorcing parents often produce more offspring in a season than those who remain with their partner, highlighting divorce as an adaptive strategy to enhance reproductive success, influenced by factors like temperature.
Maturation (the age when organisms are physiologically capable of breeding) is one of the major life history traits that have pervasive implications for reproductive strategies, fitness, and population growth. Sex differences in maturation are common in nature, although the causes of such differences are not understood. Fisher and Lack proposed that delayed maturation in males is expected when males are under intense sexual selection, but their proposition has never been tested across a wide range of taxa.

However, it remains unclear which demographic processes generate ASR variation and how biases in ASR in turn affect social behaviour. Here, we evaluate the demographic mechanisms shaping ASR and their potential consequences for parental cooperation using detailed survival, fecundity, and behavioural data on 6119 individuals from six wild shorebird populations exhibiting flexible parental strategies.
