Frequency, n: prey frequency of each taxon, n%: percentage of prey of each taxon in relation to prey number. Presence, np: number of scats in which each taxon is present and %p: percentage of scats in which each taxon is present. The number of prey items from a given taxon is estimated from the count of significant elements. Scat piles A and B corresponding to the two samples obtained in the western latrine within malacophyllous vegetation (see more details in the text)
