Abstract: Quantitative genetic parameters and the strength of lifetime selection on parturition date and litter size at birth in a natural population of North American red squirrels, Tamiasciurus hudsonicus, were estimated using an animal model. The selection analysis using lifetime fitness and average lifetime values of traits suggested that selection differed in form between the two traits examined.
