dc.description.abstract | While among-individual variation in behaviour, or personality, is common across
taxa, its mechanistic underpinnings are poorly understood. The Pace of Life syndrome
(POLS) provides one possible explanation for maintenance of personality differences.
POLS predicts that metabolic differences will covary with behavioural variation, with
high metabolism associated with risk prone behaviour and ‘faster’ life histories (e.g.,
high growth, early maturation). We used a repeated measures approach, assaying
metabolic traits (rate and scope), behaviour and growth to test these predictions in the
Trinidadian guppy, Poecilia reticulata. We found that while individuals varied
significantly in their behaviour and growth rate, more risk prone individuals did not
grow significantly faster. Furthermore, after accounting for body size there was no
support for among-individual variation in metabolic traits. Thus, while personality
differences are clearly present in this population, they do not covary with metabolism
and the POLS framework is not supported. | en_GB |
