text: The rate of growth of this parameter is equal to the first eigenvalue of the Leslie matrix.
full_question: The rate of growth of this parameter is equal to the first eigenvalue of the Leslie matrix. This parameter is predicted to oscillate in a set of dynamics that requires estimation of conversion efficiency and attack rate. The "effective" version of this parameter is smaller than the absolute form due to nonrandom mating. Genetic drift is strongest at small values for this parameter, which is required to be infinitely large for Hardy-Weinberg dynamics. In logistic growth, the long-term maximum for this parameter is the carrying capacity. For 10 points, name this parameter that describes how many individuals are in a population.
first_sentence: The rate of growth of this parameter is equal to the first eigenvalue of the Leslie matrix.
raw_answer: population size [accept effective population size; accept size after "population"; prompt on "N"]
