Abstract

Two species of Galapagos land iguanas were compared with respect to population densities and energetics. The energetic expenditures of the populations were calculated from data on body masses of the iguanas, daily patterns of body temperature and activity, and population size. The estimated energetic expenditure per individual was higher for Conolophus pallidus from Isla Santa Fe because of their larger body size, but the high population density of Conolophus subcristatus on Isla Plaza Sur resulted in an energetic expenditure approximately six times greater than that of iguanas on Santa Fe when expressed per unit land area.
