Problem-solving and spontaneous tool-using ability in European Brown Bears (Ursus arctos arctos) (2023)
Journal Article
Chambers, H., & O'Hara, S. Problem-solving and spontaneous tool-using ability in European Brown Bears (Ursus arctos arctos). Animal Behavior and Cognition, 10(1), 40-61. https://doi.org/10.26451/abc.10.01.03.2023

Little is known about the cognitive abilities of bears, despite possessing relatively large brains for their body size. One reason this group is perhaps overlooked is because they are thought to fail to conform to the “social brain” hypothesis, by be...

Why big brains? A comparison of models for both primate and carnivore brain size evolution (2021)
Journal Article
Chambers, H., Heldstab, S., & O'Hara, S. (2021). Why big brains? A comparison of models for both primate and carnivore brain size evolution. PLoS ONE, 16(12), e0261185. https://doi.org/10.1371/journal.pone.0261185

Despite decades of research, much uncertainty remains regarding the selection pressures responsible for brain size variation. Whilst the influential social brain hypothesis once garnered extensive support, more recent studies have failed to find supp... Read More about Why big brains?
