“…Studies are describing that subterranean rodents can produce signals beyond vocalizations, called seismic signals [21,22,[52][53][54][55][56][57]. These signals can be generated from the behavior of stomping feet [53,[57][58][59][60] and/or head [22,52,54,61] inside the tunnels as a way to produce noise and use it to communicate.…”

“…or long-range signals, divided into vocal and non-vocal emissions [19,20]. Among the nonvocal signals are tooth beats and vibrational emissions [17,21]. Studies describe the presence of seismic communications in some subterranean rodents [22], but these emissions have not yet been reported in Ctenomys.…”

Sound signals can travel through long distances, becoming an important communication channel between animals that need to establish contact beyond the visual form. They can then be considered a relevant form of communication between species living in the underground environment. Ctenomys torquatus and Ctenomys lami are solitary subterranean rodents, thus demanding an improvement of the communicative channels, especially in territorial defense actions and meeting potential reproductive partners. This work was aimed to describe the variability of acoustic signals emitted by C. torquatus and C. lami by analyzing the physical-morphological characteristics of the signals. The study was carried out in two populations, one of each species and was selected 14 individuals of C. torquatus and 15 C. lami. The acoustic signals were recorded in a natural environment, obtaining the sounds straight from the animal tunnels. A total of 1,380 signals were captured and analyzed, 786 from C. torquatus and 594 from C. lami. It was possible to characterize 5 different types of signals, emitted by both species. Most of the analyzed sequences presented low frequency, and many of these calls exhibited characteristics of long-range signals. It was verified a sharing of sound signals in both species, as regarding the acoustic parameters as the morphology of the analyzed spectrograms. For the first time, it was possible to have access to sound data emitted by direct subterranean rodents from their tunnels in the natural environment.

“…The primordial role of drumming on the floor could be long-distance communication (seismic), whether for sexual or warning purposes. Vocal signals originated first than seismic signals, and the use of the sound produced by the shock of the foot on the ground as a communication signal could have emerged from the digging process (Francescoli and Altuna, 1998), eventually independently in phylogenetically unrelated rodent lineages (Schleich and Francescoli, 2018). Both species showed a relative conspecific tolerance, considering time or frequency of affiliative behaviors.…”

Behavioral repertoire of the Brazilian spiny-rats, Trinomys setosus and Clyomys laticeps: different levels of sociality

Behavior is a useful trait for comparative studies that provide the comprehension of phylogenetic relationships among species. Here, we present a description of two spiny-rats species’ behavioral repertoire, Clyomys laticeps and Trinomys setosus (Rodentia: Echimyidae). The affiliative and agonistic behavioral patterns were sampled during a three-year study of captive populations of wild animals. Observational data were collected in two phases under different arrangements of individuals in groups. We also compare the behavioral traits of T. setosus and C. laticeps with the known behavioral patterns of Trinomys yonenagae. We add categories to the previous descriptions of T. setosus and a standard ethogram for C. laticeps. Trinomys setosus showed a visual and vocal display we called foot-trembling, which was not described in this form and function for other species studied until now. We discuss the differences in their sociality levels and similarities and differences among behavior patterns and repertoires.

“…Francescoli & Altuna 1998, Schleich & Francescoli 2018. Species that exploit these sounds often use their somatosensory systems for signal detection (Francescoli & Altuna 1998). Similarly, species that communicate via ultrasound must be able to detect extremely high-frequency sounds.…”

Mammals use sound for a variety of purposes, such as detecting the presence of others and maintaining social bonds. Much research on mammalian acoustics has been focussed on marine mammals and bats; less has considered terrestrial species. Our goal was to review knowledge about the role of acoustics in the behaviour and ecology of terrestrial mammals and to develop a conceptual framework that contextualises the knowledge. The purpose of the framework was to enable researchers to place their work in a broader understanding of the acoustics of terrestrial mammals, as well as to support them to articulate and explore new questions. We conducted a keyword search in Web of Science and removed papers that did not meet our criteria, resulting in 228 reviewed papers. We scored these for keywords and used concept maps to identify broad patterns. Of the 228 papers, 219 were focussed on acoustic communication. We therefore structured our Signaller–Receiver Conceptual Framework around factors that influence signallers (i.e. mammals producing sound) and receivers (i.e. mammals receiving sound). Factors that influence signallers were placed into two categories – those that influence call emission and those that influence call structure. Factors that influence receivers also fell into two categories – those that influence detection of sound and those that influence responses to sound. We added an additional receiver category – responses to sound. We present the framework in terms of five types of factors (environmental, social, morphological and physiological, state‐related factors, and other) and how they influence both signallers and receivers. Our review is the first to detail the range of factors influencing acoustic ecology of terrestrial mammals, and our framework provides context for the articulation of hypotheses that integrate multiple factors, and so can help researchers place their work in a broader context.
