Abstract

Models investigate the interaction between 3 components of fitness: 1) the intrinsic effect of egg size, 2) the density effect, the effect of the density of competing offspring (including competition with sibs and with non-sibs), and 3) the hierarchy effect, the effect of egg size relative to the sizes of competing eggs laid by other females. The environmental effects considered are the intensities of sib and non-sib competition, the number of egg-laying females, and some aspects of seasonal development. The particular aspects of maternal phenotype examined are foraging efficiency and the gametic reserve available at the time of egg laying (broadly equivalent to female size). -from Authors
