| Two different vocalization patterns for long-range (S-Type) vocal signals were detected in species of the genus Ctenomys. These patterns were described separately for C. pearsoni, C. mendocinus, and C. talarum. This paper gathers information about the vocalizations of other species, such as C. sociabilis, C. rionegrensis and C. torquatus. We confirm the existence of these patterns, identify which of those two patterns each species uses, and suggest some possible explanations about how these patterns could have originated. |
