Conceptual workflow
To answer the three goals defined above, analyses were carried out with the following conceptual workflow (Figure 2). First, the population state was described through the number of breeders, the OSR, and the level of inbreeding and relatedness between reconstructed couples. The effect of the relatedness on the fitness parameters in the clutches was investigated. Then, the reproductive behaviours of the population were described for both sexes, i.e. the reproduction frequency, nesting and/or reproductive parameters within a season, and levels of multipaternity. Finally, we tested whether these behaviours mitigate or favour inbreeding by comparing the relatedness of couples involved with the relatedness of all reconstructed couples.
