“…Despite the emphasis by early ethologists on phylogeny [28], and the statement that 'each species brings a different phylogenetic heritage into a particular ecological scene' [29], the search for environmental determinants has long overshadowed the role of evolutionary history in the study of behaviour [30]. Similar ecological problems were considered to produce similar solutions, i.e.…”

The evolutionary study of social systems in non-human primates has long been focused on ecological determinants. The predictive value of socio-ecological models remains quite low, however, in particular because such equilibrium models cannot integrate the course of history. The use of phylogenetic methods indicates that many patterns of primate societies have been conserved throughout evolutionary history. For example, the study of social relations in macaques revealed that their social systems are made of sets of correlated behavioural traits. Some macaque species are portrayed by marked social intolerance, a steep dominance gradient and strong nepotism, whereas others display a higher level of social tolerance, relaxed dominance and a weaker influence of kinship. Linkages between behavioural traits occur at different levels of organization, and act as constraints that limit evolutionary responses to external pressures. Whereas these constraints can exert strong stabilizing selection that opposes the potential changes required by the ecological environment, selective mechanisms may have the potential to switch the whole social system from one state to another by acting primarily on some key behavioural traits that could work as pacemakers.

Emission vocale de forte intensite chez Cercocebus galeritus agilis : structure, caracteristiques specifiques et individuelles, modes d'emission par R. QURIS Comme la plupart des autres especes de Cercopithecidae, Cercocebus galeriius possede dans son repertoire vocal un cri de forte intensito, propre aux males adultes. Malgre" une certaine similarite avec cclui de C. albigena sympatrique, ce cri de structure complexe est caracte*ristique de 1'espece. De plus, par la combinaison de ses paramelres de temps et de frequence, il peut probablement servir de base a une reconnaissance inter-individuelle a distance.L'emission par un individu augmente la probabilito d'omission par les males voisins, ce qui entraine un phenomene de contagion. Les cris sont amis pre"fe>entiellement au cours de la matinee. Mais dans la population de la Njadio, contrairement ä celle de la Liboui, chaque emetteur a frequemment un ou plusieurs voisins et les cris sont pratiquement tous emis par contagion des le lever du jour.Ce cri per?u ä des distances de Tordre de 5-600 metres, vohiculant des informations sur la localisation, 1'espece et probablement Tidentito de Tometteur, est propre ä servir dans les mocanismes d'espacement, function classiquement reconnue ä ce type de cri.

“…Related species, belonging to the cephus superspecies, are found in primary lowland rainforest, but also in secondary and riparian forests. Some of them, like Cercopithecus cephus Linnaeus 1758, seem to prefer younger types of forest to more mature ones (STRUHSAKER 1969). In north-east Gabon this species is found both in primary and secondary forest, but preferences are influenced by factors, such as predation, competition and food availability.…”

“…It can be found only in a small area on and around Mount Cameroon and on the island of Bioko, Equatorial Guinea (OATES 1986). While some study has been conducted with the mainland populations of this species (STRUHSAKER 1969, GART-LAN & STRUHSAKER 1972, there is little information concerning this primate on Bioko island (LEE et al 1988), where it is found in the form of an endemic subspecies (Cercopithecus erythrotis erythrotis Waterhouse 1838). Some biometrical data were published by KRUMBIEGEL (1942) and EISENTRAUT (1973).…”

Notes on habitat use by the Russet-eared guenon (Cercopithecus erythrotisWaterhouse 1838) on Bioko island, Equatorial Guinea

The Russet-eared guenon (Cercopithecus erythrotis) is one of the less studied and more threatened primate species of Africa. Habitat preference of this guenon was analyzed on Bioko island, Republic of Equatorial Guinea. Almost all the island is inhabited by this primate, that is able to live near human settlements. The Russeteared guenon is found preferentially in primary tropical forest, but can be observed also in montane and secondary forest, and even at the beaches or in the Alpine grasslands of the hiF.her mountains of the island. Russet-eared guenons were found at lower altitudes than any other guenon in the forest of Bioko island, and most of their activity took place on the lower levels of the canopy. Ecological plasticity and adaptability are shown to be the main characters of this guenon on Bioko island.
