Abstract
Summary: Data from a dropping decay experiment were re‐analysed following the finding by other workers that decay is not an exponential process. Methods based on the assumption of constant age‐specific decay gave biased estimates of the mean decay rate for the population of droppings. The best estimate was obtained by weighting the decay rate by the frequency of droppings in each age‐class.Résumé: On a réanalysé les résultats d'une expérience sur la décomposition des excréments suite au fait que d'autres chercheurs avaient trouvé que la décomposition n'est pas un processus exponentiel. Les méthodes basées sur l'hypothèse d'une décomposition constante liée à l'âge donnent des estimations biaisées du taux moyen de décomposition pour l'ensemble des excréments. On a obtenu la meilleure estimation en mettant en balance le taux de décomposition et la fréquence des déjections pour chaque classe d'âge.Keywords
