- Abstract
The authors comments on a study by Ricklefs and Cadena on the relation of lifespan to investment in reproduction in populations of mammals and birds in captivity. According to the author, while they agree that trade-offs might not be expected in benign environments such as zoos, they remain unconvinced that their analysis of phenotypic data reveals that there are no intrinsic trade-offs constraining life-history evolution within or among species. The authors argue that several confounding factors have not been adequately explained in their analyses.
