Repeatability of nest size choice and nest building in sand gobies
To be useful as mate choice cues, behavioural traits have to be performed consistently within individuals. This may also be true for nest construction, which, in addition to influencing offspring survival, can also function as an extended phenotype of the builder. We tested whether choice of a nesting resource and subsequent nest-building performance are repeatable […]
Effect of egg predator on nest choice and nest construction in sand gobies
Nest defence is a particularly costly component of parental care. The costs of nest-related behaviours are affected by the nest’s location, size and architecture; yet surprisingly little is known about how choice of a nesting site or nest characteristics are adjusted as a response to the threat of future nest predation. To address this topic, […]
