Unsupervised discovery of family specific vocal usage in the Mongolian gerbil.

In nature, animal vocalizations can provide crucial information about identity, including kinship and hierarchy. However, lab-based vocal behavior is typically studied during brief interactions between animals with no prior social relationship, and under environmental conditions with limited ethological relevance. Here, we address this gap by establishing long-term acoustic recordings from Mongolian gerbil families, a core social group that uses an array of sonic and ultrasonic vocalizations.

Whistles and click-trains emission rates were compared among different environmental, social and behavioural conditions. Structural variability of 3928 good/high-quality vocalizations was analysed in relation to contexts through a two-stage approach.

Article Synopsis
- Researchers investigated Menzerath's Law in meerkats' vocalizations, which suggests a link between the number of calls in a sequence and their length.
- They analyzed 1,676 vocal bouts from 89 wild meerkats and found that, contrary to the law, longer calls occurred when there were more calls in a bout.
- However, they did observe a negative relationship between the size of a bout and the duration of inter-call intervals, indicating complex dynamics in meerkat communication.
Male rats emit aversive 44-kHz ultrasonic vocalizations during prolonged Pavlovian fear conditioning.

Rats are believed to communicate their emotional state by emitting two distinct types of ultrasonic vocalizations. The first is long '22-kHz' vocalizations (>300 ms, <32-kHz) with constant frequency, signaling aversive states, and the second is short '50-kHz' calls (<150 ms, >32 kHz), often frequency-modulated, in appetitive situations. Here, we describe aversive vocalizations emitted at a higher pitch by male Wistar and spontaneously hypertensive rats (SHR) in an intensified aversive state - prolonged fear conditioning.

Graded call types predominate in species inhabiting open habitats with complex social systems, whereas discrete call types predominate in species with simple social systems living in closed habitats. This study aims to establish the vocal repertoire of Etruscan shrews, the smallest terrestrial mammal, which lives in pairs in closed habitats. Through various behavioral experiments, vocalizations were recorded and analyzed using unsupervised soft clustering, identifying four call types, one of which exhibited gradation.
