Resumen:
The purpose of this study was to analyse and
describe vocalizations of a solitary subterranean rodent,
Ctenomys talarum
. In adult
C. talarum
five different sounds
(four true vocalizations and one mechanical sound) were
recorded during different behavioural contexts. Using data
from the laboratory and literature, we classified these vocalizations
as territorial, distress, and mating calls. We found
that the vocalization range in
C. talarum
is shifted towards
low frequencies, which transmit better in underground
burrows and match well the hearing range described for
other species of subterranean rodents. These low-frequency
vocalizations, also found in other non-related subterranean
rodents, may reflect an adaptation to the acoustic conditions
of the habita
