We report on a 32-yr study of a population of Spanish Imperial Eagles, Aquila adalberti, which increased during the first 16 yr of study but remained stable during the last 16 yr. We analyzed changes in the mean and variance of fecundity in relation to population density to test predictions of two hypotheses of density-dependent fecundity. According to the "interference" hypothesis, as density increases, frequency of agonistic encounters increases, resulting in a relatively uniform decrease in… CONTINUE READING
