Cluster analysis for rodent species based on Bray–Curtis dissimilarity index for frequency of occurrence of 4 diet categories at Chiquintirca, Ayacucho, Peru. Two clusters are apparent; one is comprised of Thomasomys spp. but also includes Calomys sorellus due to the high levels of intact seeds and plant parts in fecal samples. The 2nd cluster is comprised of Akodon torques, Microryzomys minutus, and Oligoryzomys andinus which are omnivorous, but have lower proportions of intact seeds and plant remains in samples as compared to the 1st group.
