We provide the first systematic data on behavior and ecology of Aconaemys porteri. We used telemetry to monitor patterns of activity, resting locations, and range areas. Rock rat movements were statistically similar during nighttime and daytime, implying no clear diurnal or nocturnal activity. Animals used from 2 to 9 putative resting locations, but one was used more frequently. Rock rats showed relatively smaller range areas and low-to-moderate spatial overlap with neighbors, compared to other rodent species. These results indicate that A. porteri exhibit an intermediate level of sociality, compared to other octodontids.
