A loud call of the ruffed lemur (Varecia variegata) was analyzed for subspecific and gender differences according to four variables: pulse rate, median pulse duration, median high frequency, and median low frequency. These vocalizations of black‐and‐white and red ruffed lemurs and one hybrid ruffed lemur were recorded at the Duke University Primate Center (Durham, NC). Significant differences were found between subspecies but not between the sexes. Quantitative differences in this loud call of… Expand
Diurnal distribution of loud calls in sympatric wild indris (Indri indri) and ruffed lemurs (Varecia variegata): implications for call functions
TLDR
Differences in distribution pattern support earlier claims that indri song bouts are more likely to serve territorial functions, whereas ruffed lemur loud calls may serve both spacing and/or alarm call functions. Expand
Factors affecting call usage in wild black-and-white ruffed lemurs (Varecia variegata) at Mangevo, Ranomafana National Park.
TLDR
This study provides some of the first quantitative analyses of ruffed lemur vocal communication and lays the groundwork for more systematic hypothesis testing in future studies. Expand
Subspecific Divergence in the Black Lemur's Low-Pitched Vocalizations
Previous studies offered very preliminary information on the vocal repertoire of Eulemur macaco macaco and Eulemur macaco flavifrons. They agreed on the fact that both subspecies emit low-pitchedExpand
Species and sex differences in the screams of chimpanzees and bonobos
TLDR
One-way analyses of variance and discriminant function analyses show that the calls of chimpanzees and bonobos differ primarily in spectral characteristics, consistent with the hypothesis that optimal signals for group identification vary little within groups but differ widely between groups. Expand
Acoustically Dimorphic Advertisement Calls Separate Morphologically and Genetically Homogenous Populations of the Grey Mouse Lemur (Microcebus murinus)
TLDR
It is postulate that differences in the acoustic pattern of the advertisement call of male mouse lemurs from two neighbouring demes in a dry deciduous forest of western Madagascar are comparable to dialects in birds, because demes were morphologically and genetically indistinguishable and no barrier prevented genetic exchange between them. Expand
Do Ruffed Lemurs Form a Hybrid Zone? Distribution and Discovery of Varecia, with Systematic and Conservation Implications
TLDR
The evidence for a natural hybrid zone is examined, and a more extensive hybrid zone than previously suggested is indicated—but one in which hybridization is the exception rather than the rule. Expand
Locale‐specific Vocal Behaviour of the Tamarin (Saguinus I. labiatus)
TLDR
A quantitative acoustic analysis of long calls of red-chested moustached tamarins was undertaken after capture in the primary forest of Northwestern Bolivia, comparing two populations, and assumes populational vocal variability comparable to dialects in birds. Expand
Geographic Variation in the Long Calls of Male Orangutans (Pongo spp.)
TLDR
A quantitative acoustic analysis of orangutan long calls was undertaken, comparing flanged adult males from four geographically distinct sites across Borneo and Sumatra, revealing consistent differences among the calls of individuals and acoustic variables can be used in combination to assign calls to the correct individual, site and island at rates higher than that expected by chance.

Duet Vocalizations among Different Populations of Sulawesi Tarsiers

TLDR
Discriminant function analysis revealed that Togian tarsiers, T. spectrum and T. dianae, are clearly separated by acoustic characteristics in songs, support them being a distinct species. Expand
Species-specificity in communication calls of tree shrews (Tupaia: Scandentia)
TLDR
Loud calls may offer a reliable noninvasive tool for species diagnosis and discrimination in cryptic species of this diurnal mammalian group, supporting species status for all 3 studied tree shrew species and corroborating immunodiffusion and genetic data that differentiate T. glis and T. belangeri.

TLDR
Field recordings of male loud calls from each major form of black-and-white colobus monkey have been analyzed spectrographically, and features of tempo and pitch measured, and it is suggested that there are five species. Expand

The territories of these arboreal, forest animals are much smaller than the home ranges of more terrestrial and nonterritorial open-country primaes. Expand
Troop‐specific responses to long calls of isolated tamarins (Saguinus mystax)
TLDR
Although there was no evidence of troop‐specific call structure or dialect, there were troop‐ specific responses to the calls of separated tamarins that implies the existence of a stable and integrated troop structure that allows troop members to learn and to respond to the individual specific features of each troop member's calls.

Songs of hybrid gibbons (Hylobates lar × H. muelleri)

TLDR
The utility of sound‐spectographic analysis of hybrid vocalizations to further understanding of primate behavioral inheritance is demonstrated and it is demonstrated that H. muelleri song is uniquely different from either parental type. Expand
Inheritance of Song Parameters in the Gibbon Song, Analysed in 2 Hybrid Gibbons (Hylobates pileatus × H. lar)
TLDR
Comparison with thesong of both parental species revealed that at least some of the hybrid’s song characteristics were inherited, and attention is drawn to similarities between the song of the hybrids and gibbon species other than the parental ones, and their significance is considered. Expand

TLDR
A new estimate of the phylogenetic relationships among the nine gibbon taxa is presented, based on a compatibility analysis of 55 morphological and behavioural characters, which appears to be a basic consensus that the siamang and concolor gibbons represent the earliest forms to speciate. Expand

Despite the presence of substantial maturational changes in IP's, the data reveal individuality or vocal signature at all ages tested and the animals had developed by the end of the study unique and stable IP's comparable to those recorded previously from wild-caught adults. Expand
