Classification of Captive North American River Otters (Lontra canadensis) Vocal Repertoires: Individual Variations, and Age Class Comparisons [PDF]
Animal Behavior and Cognition, 2014 This is the first study to examine in detail the vocal behaviors of North American river otters (Lontra canadensis), and the results suggest that river otters have complex vocal repertoires comprised of four distinct vocal types and seven sub-call types.

Social Context Predicts Vocalization Use in the Courtship Behaviors of Weddell Seals (Leptonychotes weddellii): A Case Study [PDF]
Animal Behavior and Cognition, 2016 Despite previous research, no study has convincingly demonstrated what role if any vocalizations might play in the reproductive behavior of Weddell seals (Leptonychotes weddellii). To better understand that role, we created an artificial territory for an

Fuzzy clustering as a tool to differentiate between discrete and graded call types [PDF]
JASA Express Letters, 2021 Animals may communicate potential information to conspecifics using stereotyped “discrete” calls and variable “graded” calls. However, animal vocal research often centers on identifying the number of call types in a repertoire rather than quantifying the

Determinants of the mouse ultrasonic vocal structure and repertoire [PDF]
Neuroscience & Biobehavioral Reviews, 2016 Mouse ultrasonic vocalizations (USV) exhibit a high degree of complexity as demonstrated in recent years. A multitude of factors have been identified to influence USVs on the spectrotemporal as well as structural - e.g. syntactic - level. A synthesis of the various studies that attributes semantics to USV properties or sequences is still lacking ...

Encoding of situations in the vocal repertoire of piglets (Sus scrofa): a comparison of discrete and graded classifications. [PDF]
PLoS ONE, 2013 Two important questions in bioacoustics are whether vocal repertoires of animals are graded or discrete and how the vocal expressions are linked to the context of emission. Here we address these questions in an ungulate species.

A comparative study of the function of heterospecific vocal mimicry in European passerines [PDF]
, 2007 Although heterospecific vocal imitation is well documented in passerines, the evolutionary correlates of this phenomenon are poorly known. Here, we studied interspecific variation in vocal mimicry in a comparative study of 241 European songbirds.
