Macaques are one of the most successful nonhuman primates, and morphological distinctions from their close relatives, African papionins, are easily detected by the naked eye. Nevertheless, evolutionary allometry often accounts for a large amount of the total variation and potentially hides and precludes the detection of morphological distinctions that exist between macaques and African papionins, thus distorting their phyletic comparison. Geometric morpgometric analyses were performed using land...
The nasal cavity conditions respiratory air. The distribution of temperature within the nasal cavity has been examined in humans using various direct measurements. Macaques are a nonhuman primate species that are used as a model for understanding human physiology. They are widely distributed geographically in varied climate environments and they are expected to exhibit evolutionary anatomical and physiological adaptations in the air-conditioning. To provide basic data for developing an animal mo...

Despite the accumulating evidence suggesting the importance of phenotypic plasticity in diversification and adaptation, little is known about plastic variation in primate skulls. The present study ...
Voluntary control of vocal production is an essential component of the language faculty, which is thought to distinguish humans from other primates. Recent experiments have begun to reveal the capa...
While the call repertoire and its communicative function is relatively well explored in Japanese macaques ( Macaca fuscata ), little empirical data is available on the physics and the physiology of this species9 vocal production mechanism. Here, a 6 year old female Japanese macaque was trained to phonate under an operant conditioning paradigm. The resulting “coo” calls, and spontaneously uttered “growl” and “chirp” calls, were recorded with sound pressure level (SPL) calibrated microphones and e...
