Southernmost occurrence of Cuniculus paca (Rodentia, Cuniculidae): new Argentinean localities based on vouchers
Limited vouchered records exist for Cuniculus paca, the second-largest living caviomorph rodent, documenting its southernmost occurrence. Here, we introduce four new recording sites based on skulls probably discarded by local hunters, with three located in Misiones Province and the fourth marking the first supported evidence in the neighboring Corrientes Province in Argentina. The data remains inconclusive as to whether the latter location signifies a southern expansion of this rodent due to climate change or simply an overlooked population that has long been established. Regardless, these findings underscore the importance of increased fieldwork and specimen collection.
期刊介绍:
Mammalia is an international, multidisciplinary, bimonthly journal devoted to the inventory, analysis and interpretation of mammalian diversity. It publishes original results on all aspects of the systematics and biology of mammals with a strong focus on ecology, including biodiversity analyses, distribution habitats, diet, predator-prey relationships, competition, community analyses and conservation of mammals. The journal also accepts submissions on sub-fossil or recently extinct mammals.
