TL;DR: Female associations in a wild population of eastern grey kangaroos are investigated and it is found that space use had a much stronger correlation with association strengths than both pairwise relatedness and maternal lineage, suggesting that familiarity may play a key role in driving association patterns in female kangarooos.

TL;DR: It is shown that extensive home range overlap among communities can occur in the absence of behaviours usually associated with the maintenance of social preferences, suggesting that social preferences also influence the presence of communities in female kangaroos.

TL;DR: Five different enzyme immunoassays (EIAs) for monitoring adrenocortical activity via FGM in 13 marsupial species were compared and the ability to confidently assess assay performance was influenced by the experimental protocols used.

TL;DR: Female kangaroos tended to adjust their behaviours similarly in relation to ecological and social conditions, supporting the ecological hypothesis, however, they also showed differences in personality and plasticity in connection to their reproductive states that could not be explained by energetic demand alone.

TL;DR: Testing the relationship between individual-level traits, including boldness, body condition and reproductive state, and vigilance, while controlling for environmental and social variables found preliminary support for studies of animal personality that have suggested that boldness may covary with vigilance.
