- Through the study of a late Holocene sample of small mammal remains from central Patagonia (Chubut province, Argentina) we document the regional extinction of four sigmodontines and one fossorial caviomorph rodent. This diversity loss is discussed in the light of two potential causes: Little Ice Age and human impact. We conclude that probably the latter was the main reason behind the current structure of small mammal communities.
