Abstract:: We propose to study the genetic basis of selection for 'gigantism' in an island-dwelling bird, a striking and widespread phenomenon that has stimulated much ecological debate but has not been investigated in a quantitative fashion. Our study has two aims. (1) Employ cross-fostering experiments to quantify selection, heritability and genetic covariance associated with size and foraging behaviour. This will test the traditional explanation for insular gigantism, based on the assumption that large body size facilitates ecological niche expansion. (2) Test the utility of new marker-based methodologies for quantifying selection and quantitative genetic parameters without the need for cross-fostering or pedigree information. If such marker-based methods are practical for use in wild vertebrate populations, they promise to revolutionise the study of selection.
