Variation in percentage of recruitment (all points are model fits and standard errors). (a) Controlling for the competitive environment juveniles face, the offspring recruitment of poorly reared mothers (bad) was higher than well reared mothers and more-so when parental food is delayed at maturity (5=5 day delay in food). (b) Furthermore, recruitment of offspring of older mothers increased with increasing parental density while recruitment of offspring of young mothers decreased with increasing density. (c) These patterns occur despite controlling for variation in recruitment associated with juvenile density and food. Recruitment declined exponentially with increasing juvenile density, and more steeply with food was limited to a pulse at hatching.
