Personality underground: evidence of behavioral types in the solitary subterranean rodent Ctenomys talarum.

ABSTRACT:

Background

Animal personalities have been studied in a wide variety of taxa, but among rodents, available studies are relatively scarce and have focused mainly on social species. In this study, we evaluated the existence of personality in the solitary subterranean rodent Ctenomys talarum. Specifically, we aimed to test individual differences in behavior that are stable over time and context in males of C. talarum captured in the wild.

Methods

Our experimental design included two series of three behavioral tests each, carried out with a 35 day time interval. Each series included an Open Field test, a Social Encounter test, and an Open Field test with a predator stimulus.

Results

Of the total recorded behaviors, 55.55% showed temporal consistency. Principa
