Primates . 2024 Sep; 65(6):515-524. PMID: 39287698
Non-human primates generally lack the ability to learn new call structures or to substantially modify existing ones, suggesting that callers need alternative mechanisms to convey information. One way to escape...

Primates . 2024 Sep; 65(6):469-478. PMID: 39283353
Many non-human primates form heterospecific associations to increase benefits resulting from group living like antipredation defence and increased foraging efficiency while avoiding costly resource competition that usually arises from large...

Robbins M, Akantorana M, Arinaitwe J, Breuer T, Manguette M, McFarlin S, et al.
Am J Biol Anthropol . 2023 Jun; 181(4):564-574. PMID: 37345324
Objectives: Several theories have been proposed to explain the impact of ecological conditions on differences in life history variables within and between species. Here we compare female life history parameters...

Robbins A, Manguette M, Breuer T, Groenenberg M, Parnell R, Stephan C, et al.
PLoS One . 2022 Oct; 17(10):e0275635. PMID: 36260834
Long-term studies of population dynamics can provide insights into life history theory, population ecology, socioecology, conservation biology and wildlife management. Here we examine 25 years of population dynamics of western...

Mehon F, Stephan C
R Soc Open Sci . 2021 May; 8(3):202135. PMID: 33959365
Alarm calls can trigger very different behavioural changes in receivers and signallers might apply different alarm call strategies based on their individual cost-benefit ratio. These cost-benefit ratios can also vary...

Health Policy Plan . 2019 Nov; 35(1):78-90. PMID: 31697378

Stephan C, Zuberbuhler K
Curr Biol . 2017 Jan; 26(21):2907-2912. PMID: 28094027
Sexual dimorphisms in animal vocal behavior have been successfully explained by sexual selection theory (e.g., mammals [1-5]; birds [6, 7]; anurans [8, 9]), but this does not usually include alarm...

Stephan C, Zuberbuhler K
R Soc Open Sci . 2016 Mar; 3(2):150639. PMID: 26998336
Male Diana monkeys produce loud and acoustically distinct alarm calls to leopards and eagles that propagate over long distances, much beyond the immediate group. Calling is often contagious, with neighbouring...

J Comp Psychol . 2014 Aug; 128(3):261-75. PMID: 25133466
The type of stimulus material employed in visual tasks is crucial to all comparative cognition research that involves object recognition. There is considerable controversy about the use of 2-dimensional stimuli...
