Pup Recruitment in a Eusocial Mammal-Which Factors Influence Early Pup Survival in Naked Mole-Rats?

In eusocial insects, offspring survival strongly depends on the quality and quantity of non-breeders. In contrast, the influence of social factors on offspring survival is more variable in cooperatively breeding mammals since maternal traits also play an important role. This difference between cooperative insects and mammals is generally attributed to the difference in the level of sociality.
