Westover L, Morris-Drake A, Layton M, Kern J, Arbon J, Radford A
Biol Lett . 2025 Feb; 21(2):20240645. PMID: 39933570
Anthropogenic noise is a pervasive pollutant in the world's ecosystems, with numerous studies demonstrating negative physiological, developmental and behavioural impacts across taxa. However, research has tended to focus on anthropogenic...

Arbon J, Morris-Drake A, Kern J, Giuggioli L, Radford A
Behav Ecol . 2024 Oct; 35(6):arae082. PMID: 39473884
When making decisions about resource use, social species must integrate not only environmental factors but also the influence of opportunities and costs associated with group living. Bigger groups are expected...

Arbon J, Morris-Drake A, Kern J, Howell G, Wentzel J, Radford A, et al.
R Soc Open Sci . 2024 Oct; 11(10):241125. PMID: 39359473
Cooperatively breeding societies show distinct interspecific variations in social and genetic organization. Long-term studies provide invaluable data to further our understanding of the evolution and maintenance of cooperative breeding but...

Vane L, Morris-Drake A, Arbon J, Thomson R, Layton M, Kern J, et al.
R Soc Open Sci . 2024 Jul; 11(5):240192. PMID: 39076821
Anthropogenic (man-made) noise constitutes a novel and widespread pollutant which is increasing in prevalence in terrestrial and aquatic ecosystems, resulting in alterations of natural soundscapes. There is proliferating evidence that...

Morris-Drake A, Cobb B, Kern J, Radford A
Proc Biol Sci . 2023 Nov; 290(2011):20231853. PMID: 37964527
Outgroup conflict is a powerful selective force across all social taxa. While it is well documented that individual outgroup contests can have a range of direct and indirect fitness consequences,...

Kern J, Morris-Drake A, Radford A
Proc Biol Sci . 2023 Aug; 290(2005):20230901. PMID: 37583317
Social instability frequently arises in group-living species, but the potential costs have rarely been investigated in free-living cooperative breeders, especially across different timeframes. Using natural observations, body mass measurements and...

Morris-Drake A, Linden J, Kern J, Radford A
Proc Biol Sci . 2021 Dec; 288(1964):20211743. PMID: 34875195
Conflict between rival groups is rife in nature. While recent work has begun exploring the behavioural consequences of this intergroup conflict, studies have primarily considered just the 1-2 h immediately...

Morris-Drake A, Kern J, Radford A
Elife . 2021 Nov; 10. PMID: 34725038
In many species, within-group conflict leads to immediate avoidance of potential aggressors or increases in affiliation, but no studies have investigated delayed post-conflict management behaviour. Here, we experimentally test that...

Kern J
Curr Biol . 2021 Sep; 31(18):R1082-R1084. PMID: 34582815
In cooperatively breeding animals, much of the variation in the quantity of help provided by group members remains unexplained. A new study on an Australian songbird suggests we need to...

Morris-Drake A, Christensen C, Kern J, Radford A
Behav Ecol . 2019 Oct; 30(5):1425-1435. PMID: 31579132
In social species, conspecific outsiders present various threats to groups and their members. These out-group threats are predicted to affect subsequent within-group interactions (e.g., affiliation and aggression) and individual behavior...
