“…Social environment (familiarity) and probably social ties (maternal kinship) may therefore modulate voice features, as does genetic information. Whereas vocal plasticity at the individual level is well documented in songbirds 24 , parrots, dolphins and seals 20 , studies showing socially guided flexibility in primate calls are still sparse (for example, refs [25][26][27]. Conversely, several studies have shown the vocal repertoire of primates to be fixed and genetically determined.…”

Social shaping of voices does not impair phenotype matching of kinship in mandrills

Kin selection theory provides a strong theoretical framework to explain the evolution of altruism and cooperative behaviour among genetically related individuals. However, the proximate mechanisms underlying kin discrimination, a necessary process to express kin-related behaviour, remain poorly known. In particular, no study has yet unambiguously disentangled mechanisms based on learned familiarity from true phenotype matching in kin discrimination based on vocal signals. Here we show that in addition to genetic background, social accommodation also shapes individual voices in an Old World monkey (Mandrillus sphinx), even though primate vocalizations were thought to be innate and little flexible. Nonetheless, social shaping of voice parameters does not impair kin discrimination through phenotype-matching of unknown relatives, revealing unexpected discriminatory versatility despite signal complexity. Accurate signal production and perception, therefore, provide a basis for kin identification and kin-biased behaviour in an Old World primate.

“…In the Cheiro-galeidae, the social system is usually either a dispersed multi-male/multi-female group (M. berthae , M. ravelobensis , M. rufus and M. zaza) or a dispersed or gregarious family group composed of an adult pair with or without offspring (Cheirogaleus spp. and P. pallescens) [Charles-Dominique and Petter, 1980;Atsalis, 1998Atsalis, , 2000Müller, 1998Müller, , 1999aFietz, 1999Fietz, , 2003Schwab, 2000;Schülke, 2002;Radespiel et al, 2003;Schülke and Kappeler, 2003;Weidt et al, 2004;Braune et al, 2005;Dammhahn and Kappeler, 2005;Kappeler et al, 2005;Lahann, 2007Lahann, , 2008. Male or female uni-sex pairs (M. griseorufus) , female groups with solitary males (M. murinus) or solitary females with offspring and solitary males (M. coquereli) have also been observed [Martin, 1973;Pagès, 1978;Kappeler, 1997a, b;Radespiel, 1998Radespiel, , 2000Schmelting, 2000;Schwab, 2000;Eberle and Kappeler, 2002;Wimmer et al, 2002;Radespiel et al, 2003;Génin, 2008;Lahann, 2008].…”

In this study we describe tree hole characteristics and use by the hairy-eared dwarf lemur (Allocebus trichotis) to determine habitat needs, potential functions of tree holes and sleeping group composition. We radio-tracked 6 adult individuals between April and November 2007 in the Analamazaotra Special Reserve. Tree holes were 1–9 m high (median: 7 m), in living trees measuring 26–54 cm in diameter at breast height (median: 32 cm), and could be a limiting resource. Each individual used 4 or 5 tree holes and had high nest fidelity. Animals most often slept socially in mixed-sex groups of 2–6 individuals and occasionally shared a tree hole with white-tailed tree rats (Brachytarsomys albicauda). We identified two sleeping groups: one composed of 2 adult males, 2 adult females and 2 juveniles; one composed of at least 2 adult females and 2 juveniles. Although tree holes were generally group exclusive, some intergroup sleeping was observed. Tree holes could have antipredator and thermoregulatory functions. Further research into sleeping hole availability, nest use and the degree of niche separation or competition between sympatric Cheirogaleidae and other tree hole users (e.g. endemic rodents) is needed to assess better the conservation needs of these species.

“…For owl monkeys (Aotus), the functional significance of such enhanced hearing is uncertain; all recorded vocalizations are contained below 10 kHz [2]. Other primates-Callithrix, Cebuella, Cheirogaleus, Galago, Microcebus, Nycticebus, Prolemur-can emit and respond to calls with ultrasonic components [3][4][5][6][7][8]; however, the dominant frequencies are always well within the human audible range. Thus, the prospects for primate communication solely within the ultrasound, or pure ultrasound [9], appear limited.…”

Primate communication in the pure ultrasound

Few mammals-cetaceans, domestic cats and select bats and rodents-can send and receive vocal signals contained within the ultrasonic domain, or pure ultrasound (greater than 20 kHz). Here, we use the auditory brainstem response (ABR) method to demonstrate that a species of nocturnal primate, the Philippine tarsier (Tarsius syrichta), has a high-frequency limit of auditory sensitivity of ca 91 kHz. We also recorded a vocalization with a dominant frequency of 70 kHz. Such values are among the highest recorded for any terrestrial mammal, and a relatively extreme example of ultrasonic communication. For Philippine tarsiers, ultrasonic vocalizations might represent a private channel of communication that subverts detection by predators, prey and competitors, enhances energetic efficiency, or improves detection against low-frequency background noise.
