摘要: Background The diet of free-ranging carnivores is an important part their ecology. It often determined from prey remains in scats. In many cases, scat analyses are the most efficient method but they require correction for potential biases. When expressed as proportions consumed mass each species, to excrete one needs be and corrected body because proportion digestible indigestible matter increases with mass. Prey can by conducting feeding experiments using various masses fitting a regression between (correction factor 1). individuals species includes animals not completely consumed, actual carnivore controlled 2). No previous study this second bias.
