- aPercentage of males that had more than one female mate
- bPercentage of females that had more than one male mate
- cPercentage of males that failed to reproduce from the total number of males with breeding recommendations
- dPercentage of females that failed to reproduce from the total number of females with breeding recommendations
- eAverage individual reproductive contribution (number of joeys produced as a proportion of the total number of joeys produced in that yearly cohort)
- fAverage litter size value obtained only from females that reproduced during this study
- gIn these two years, breeding recommendations were preferentially giving to group housing facilities due to capacity restrictions in the intensive facilities in the insurance population ([52])
- Group housing facilities provide an opportunity for mate choice, and intensive housing facilities require forced monogamy
