“…Most of the calls were emitted immediately after birth and their number decreased on subsequent days. This is consistent with other studies (Hashimoto et al, 2001b(Hashimoto et al, , 2004. Juvenile golden hamsters produce the strongest ADVs when they produce the weakest USVs.…”

a b s t r a c tIsolated juvenile golden hamsters produce ultrasonic and audible vocalizations, so-called isolation calls, as a reaction to being separated from their mother and nest and their cooling down. Their aim is to stimulate mothers to search and retrieve the pups. In this work, the vocalization of juvenile laboratory (Zoh:GOHA; Institute of Zoology, Martin-Luther-University Halle-Wittenberg) and juvenile wild-derived golden hamsters (captured in northern Syria and southern Turkey) from birth up to the age of 18 days were digitally recorded, analyzed and compared using an ultrasonic microphone and the software Avisoft. Furthermore, the retrieving behavior of the mothers was observed and compared. The results showed that the number of isolation calls was age-specific and the structure of the calls was influenced by body temperature, body mass and sex of the pups. The age of the pups determined retrieval by the maternal golden hamsters; however these did not discriminate between their own pups or foreign pups. In spite of enormous genetic differences between wild-derived and laboratory golden hamsters, only minor differences between the strains were found.

“…The isolation-induced USV calls of yellow steppe lemmings emerged since 1 st day of pup life. In other rodents (gerbils, mice, California mice, voles, rats, hamsters), the isolation-induced USV calls emerge since 1 st -3 th day of life, depending on the species [26,46,104,106,[113][114][115][116][117][118][119][120][121][122][123][124], for exclusion of fat-tailed gerbils, in which the isolation-induced USV calls emerge only since 5 th day of life [39].…”

Ultrasonic vocalizations (USV) of laboratory rodents may serve as age-dependent indicators of emotional arousal and anxiety. Fast-growing Arvicolinae rodent species might be advantageous wild-type animal models for behavioural and medical research related to USV ontogeny. For the yellow steppe lemming Eolagurus luteus, only audible calls of adults were previously described. This study provides categorization and spectrographic analyses of 1176 USV calls emitted by 120 individual yellow steppe lemmings at 12 age classes, from birth to breeding adults over 90 days (d) of age, 10 individuals per age class, up to 10 USV calls per individual. The USV calls emerged since 1 st day of pup life and occurred at all 12 age classes and in both sexes. The unified 2-min isolation procedure on an unfamiliar territory was equally applicable for inducing USV calls at all age classes. Rapid physical growth (1 g body weight gain per day from birth to 40 d of age) and the early (9-12 d) eyes opening correlated with the early (9-12 d) emergence of mature vocal patterns of USV calls. The mature vocal patterns included a prominent shift in percentages of chevron and upward contours of fundamental frequency (f0) and the changes in the acoustic variables of USV calls. Call duration was the longest at 1-4 d, significantly shorter at 9-12 d and did not between 9-12-d and older age classes. The maximum fundamental frequency (f0max) decreased with increase of age class, from about 50 kHz in neonates to about 40 kHz in adults. These ontogenetic pathways of USV duration and f0max (towards shorter and lower-frequency USV calls) were reminiscent of those in laboratory mice Mus musculus.

“…Variations in the sounds of these vocalizations have been associated with handling, cold temperatures, isolation, and various social factors (Blumberg et al, 1992; Shair et al, 1997; Branchi et al, 2001; Hahn and Lavooy, 2005). In addition to retrieval, vocalizations may also elicit maternal consumption of pup excretions during anogenital licking (Brouette-Lahlou et al, 1992) and may directly stimulate prolactin secretions in dams, although some controversy exists (Terkel et al, 1979; Stern et al, 1984; Hashimoto et al, 2001). In this context, crying is often viewed as a motivated behavior.…”

The purpose of this article is to describe the development of translational methods by which spectrum analysis of human infant crying and rat pup ultrasonic vocalizations (USVs) can be used to assess potentially adverse effects of various prenatal conditions on early neurobehavioral development. The study of human infant crying has resulted in a rich set of measures that has long been used to assess early neurobehavioral insult due to non-optimal prenatal environments, even among seemingly healthy newborn and young infants. In another domain of study, the analysis of rat put USVs has been conducted via paradigms that allow for better experimental control over correlated prenatal conditions that may confound findings and conclusions regarding the effects of specific prenatal experiences. The development of translational methods by which cry vocalizations of both species can be analyzed may provide the opportunity for findings from the two approaches of inquiry to inform one another through their respective strengths. To this end, we present an enhanced taxonomy of a novel set of common measures of cry vocalizations of both human infants and rat pups based on a conceptual framework that emphasizes infant crying as a graded and dynamic acoustic signal. This set includes latency to vocalization onset, duration and repetition rate of expiratory components, duration of inter-vocalization-intervals and spectral features of the sound, including the frequency and amplitude of the fundamental and dominant frequencies. We also present a new set of classifications of rat pup USV waveforms that include qualitative shifts in fundamental frequency, similar to the presence of qualitative shifts in fundamental frequency that have previously been related to insults to neurobehavioral integrity in human infants. Challenges to the development of translational analyses, including the use of different terminologies, methods of recording, and spectral analyses are discussed, as well as descriptions of automated processes, software solutions, and pitfalls.
