The repertoire of airborne and substrate-borne communications is described for two species of mote-voles: Microtus (Terrícola) gerbei {de Séiys-Longchamps, 1847) and M. (T.) duodecimcostatus (de Sélys-Longchamps, 1839). The behavioural significance of the different types of sounds emitted was analysed from observations of intraspecific interactions in captive environments. Substrate-borne signals were used more often by dominant individuals, and were predominantly recorded in the more aggressive species, M. duodecimcostatus. The use of substrate-borne signals is much more prevalent in the more aggressive M. duodecimcostatus, while the less aggressive M. gerbei has a larger acoustical repertoire.

Adapted social behavior allows both individual and collective well‑being. At the individual level, it is a hallmark of health. Indeed, virtually all mental health disorders are associated with social deficits. We are interested in understanding the behavioral, neural, and neurochemical bases of social cognition and communication using mouse models. Here, we will review our recent data showing the crucial role of the prefrontal cortex in the organisation of adapted social interaction, the interplay between the cholinergic and the noradrenergic systems for the balance between affiliative interaction, dominance, and control of aggressiveness, and we will discuss the putative role of ultrasonic communication in social interactions in adult animals. We will see the role played by the environment of life and by the context in which interactions take place in healthy individuals and in pathological situations. Together, the data presented will offer a novel focus on the social brain – and social life – of rodents and provide some practical recommendations for future experiments.

Calls emitted by newborn pups of Ctenomys pearsoni Lessa and Langguth, 1983 away from the nest were frequency modulated succesive notes. The notes were characterized by mean maximum frequency under 5165 Hz, with mean main frequency under 2155 Hz, and mean note duration under 0.165 s. Their possible function as contact or distress calls, resulting in recovering to the nest by the mother, is discussed.

Many traits influence birdsong diversity. Patterns observed in the acoustic parameters can be a result of morphological constraint and can also be explained by phylogenetic relationships. Understanding morphologic mechanisms that can act on song structure might account how they can catalyze speciation and how they evolve in lineages sort. We analyzed the evolution of beak volume and song constraints in "finch-like" species of Neotropical seedeaters. We tested if beak volume limits the song structure of territorial songs, based on differences in the beaks of 19 species from the genus Sporophila (Thraupidae, tanagers). We also tested (1) if body size constrained song structure, and (2) if beak volume and body size were related to each other. The relationship of song parameters (e.g. maximum and minimum frequencies, frequency bandwidth and note rate) to these two morphological variables was evaluated through an analysis which phylogenetic relations were controlled (PGLS), testing a null and Brownian model. To perform a faithful analysis between morphologic and acoustic parameters, our data was based on measurements of the beak and territorial song for each individual that we analyzed. None of the analyzed parameters was related to beak volume or body mass, and beak volume was not associated with body mass. Beak volume, note rate, and minimum frequency showed a phylogenetic signal. These results do not support the theoretically motivated prediction that beak size acts as a limit on song structure in oscine birds. The shape and variations of song in Sporophila tanagers (Seedeaters) may be a consequence of the species' phylogenetic history, since the seedeaters showed wide plasticity in many acoustic parameters, unrelated to their beak volume and body mass. Song structure was better explained by the evolutionary relationships among the species than by morphological constraints.

We recorded social vocalizations from two sympatric species of glossophagine bats, Glossophaga soricina and G. commissarisi, using habituated captive groups that were housed in separate flight cages. Whenever possible, the species-specific vocalization types were described in the light of the social context in which they were produced. Several vocalization types within each species' repertoire had remarkable similarities to vocalization types in the other species' repertoire. Out of these, four vocalization types with interspecific acoustic similarities (approach pulses, distress calls, aggressive trills, and alert calls) were used in similar behavioral contexts in both species. Approach pulses were produced whenever a bat was flying towards an already occupied roost. Distress calls were uttered whenever a bat was attacked by conspecifics or restrained by the observer, whereas aggressive trills were produced during aggressive encounters prior to physical contact. Alert calls were uttered when bats were disturbed or when several individuals were circling the same location. The interspecific similarity of both the social context and the acoustic structure of vocalization types suggest that the potential for interspecific communication is high in G. soricina and G. commissarisi.
