DOI: 10.1007/s00265-021-03076-3

Abstract: In species that live in family groups, such as cooperative breeders, inbreeding is usually avoided through the recognition of familiar kin. For example, individuals may avoid mating with conspecifics encountered regularly in infancy, as these… read more here.

DOI: 10.1016/j.anbehav.2019.03.018

Abstract: Many animals use visual signals to indicate their aggressive intentions. While much research has focused on these signals as predictors of an individual's behavioural motivations, how these social signals are perceived by others and whether… read more here.

DOI: 10.1016/j.ygcen.2018.05.018

Abstract: Dominant females of cooperative breeding species often use aggression to suppress reproduction of subordinate females, resulting in subordinates experiencing stress-related increases in glucocorticoid levels, which may cause reproductive down-regulation. This would suggest a general pattern… read more here.

DOI: 10.1038/s41467-017-01299-5

Abstract: Kin selection theory provides one important explanation for seemingly altruistic helping behaviour by non-breeding subordinates in cooperative breeding animals. However, it cannot explain why helpers in many species provide energetically costly care to unrelated offspring.… read more here.

DOI: 10.1093/beheco/arad023

Abstract: Cooperative breeding, where more than two individuals invest in rearing a single brood, occurs in many bird species globally and often contributes to improved breeding outcomes. However, high temperatures are associated with poor breeding outcomes… read more here.

DOI: 10.1098/rsbl.2019.0314

Abstract: In cooperatively breeding species, social conflict is typically assumed to underlie destructive behaviours like infanticide. However, an untested alternative hypothesis in birds is that infanticide in the form of egg tossing may simply be a… read more here.

Abstract: Multilevel societies (MLSs), where social levels are hierarchically nested within each other, are considered one of the most complex forms of animal societies. Although thought to mainly occurs in mammals, it is suggested that MLSs… read more here.

DOI: 10.1111/eth.12838

Abstract: Helping behaviour in cooperative breeders has been intensively studied in many animal taxa, including arthropods, birds and mammals. In these highly social systems, helpers typically engage in brood care and the protection of dependent young.… read more here.

DOI: 10.1111/jeb.13712

Abstract: Age‐related changes in parental phenotypes or genotypes can impact offspring fitness, but separating germline from nongermline transgenerational effects of ageing is difficult for wild populations. Further, in cooperatively breeding species, in addition to parental ages,… read more here.
