Hair structure of small rodents from central Argentina: A tool for species identification

Mammal hairs differ among species and may therefore be used for diagnoses at the species level. We characterized dorsal guard hairs of most small rodent species that may be found in central Buenos Aires province (Argentina), according to their geographic distribution: Cavia aperea, Rattus rattus, R....
