Consequences for life history
Background: It has been repeatedly suggested that differences in BT are associated with differences in key life-history traits such as growth, fecundity and mortality. Behavioural traits like boldness or activity may be directly related to mortality risks, resource acquisition and resource holding potential. Additionally, BT tend to differ systemically in the underlying physiological machinery, including metabolism, which can also affect immune function, growth- and reproduction rates, physiological fitness and ageing .
The goal of this subproject is to further investigate the relation between BT and life history. Our main hypothesis is that BT differ systematically in traits associated with life history (growth, maturation, fecundity, mortality, senescence).
