Maternal size and age shape offspring size in a live-bearing fish, Xiphophorus birchmanni.

Abstract excerpt

Many studies of offspring size focus on differences in maternal investment that arise from ecological factors such as predation or competition. Classic theory predicts that these ecological factors will select for an optimal offspring size, and therefore that variation in a given environment will be minimized.
