Effects of elevated carbon dioxide on male and female behavioural lateralization in a temperate goby.

ABSTRACT: Behavioural abnormality in fishes has been proposed as a significant consequence of the increasing levels of carbon dioxide occurring in the oceans. Negative effects of elevated CO₂ have been reported for behaviours such as predator-prey interactions, foraging, hearing and behavioural lateralization. Importantly, the effects vary greatly both within and between species, and some recent studies have shown minimal effects of CO₂ on behaviour. Whether the effect of CO₂ also varies between males and females is, however, virtually unexplored. According to resource allocation theory, females are expected to be more sensitive to elevated CO₂, meaning that non-sex-specific studies may overlook ecologically important differences between the sexes.
