Project description

The following questions are addressed: (i) Do life-history traits and phenotypic traits differ among L. argentatus colonies that differ in structure and breeding density, and does this affect trade-off functions and reaction norms ? (ii) Are trade-offs masked by variation in food availability? (iii) Do trade-off functions correlate with environmental parameters, genetic drift, parental investment, dispersal and maturation rates.
