“…Females form linear dominance hierarchies (Jones 1980), and infant survival is highly correlated with female rank (Glander 1992), as expected if the level of WGC for food is high. Yet they neither have formal signals of submission nor use coalitions to make the hierarchies nepotistic (Jones 1980;Glander 1992). Females evict other females from groups and strongly resist immigrants, who have di culty entering groups and succeed only with male help (Glander 1992).…”

“…The model does not account for female eviction and forced dispersal. Second, WGC produces despotic female hierarchies and a ects female reproductive success in female mantled howlers (Jones 1980;Glander 1992) and some hanuman langurs (Presbytis entellus: Borries 1993), but females do not form nepotistic dominance hierarchies. Third, ring-tailed lemurs show formal dominance but have unstable, nonlinear hierarchies, perhaps because of sensory constraints on their ability to give consistent coalitionary support (Pereira 1993(Pereira , 1995.…”

Considerable interspeci®c variation in female social relationships occurs in gregarious primates, particularly with regard to agonism and cooperation between females and to the quality of female relationships with males. This variation exists alongside variation in female philopatry and dispersal. Socioecological theories have tried to explain variation in female-female social relationships from an evolutionary perspective focused on ecological factors, notably predation and food distribution. According to the current``ecological model'', predation risk forces females of most diurnal primate species to live in groups; the strength of the contest component of competition for resources within and between groups then largely determines social relationships between females. Social relationships among gregarious females are here characterized as Dispersal-Egalitarian, Resident-Nepotistic, Resident-Nepotistic-Tolerant, or Resident-Egalitarian. This ecological model has successfully explained di erences in the occurrence of formal submission signals, decided dominance relationships, coalitions and female philopatry. Group size and female rank generally a ect female reproduction success as the model predicts, and studies of closely related species in di erent ecological circumstances underscore the importance of the model. Some cases, however, can only be explained when we extend the model to incorporate the e ects of infanticide risk and habitat saturation. We review evidence in support of the ecological model and test the power of alternative models that invoke between-group competition, forced female philopatry, demographic female recruitment, male interventions into female aggression, and male harassment. Not one of these models can replace the ecological model, which already encompasses the between-group competition. Currently the best model, which explains several phenomena that the ecological model does not, is a``socioecological model'' based on the combined importance of ecological factors, habitat saturation and infanticide avoidance. We note some points of similarity and divergence with other mammalian taxa; these remain to be explored in detail.

“…Aunque se han reportado casos donde las hembras paren gemelos, estos son muy raros (Chapman & Chapman 1986), por lo que en nuestros escenarios se estableció un máximo de una cría por parto. Los machos de A. palliata tienen una gran probabilidad de morir antes de alcanzar el primer año de vida, con valores cercanos al 50%, mientras que para las hembras dicha probabilidad es baja (Glander 1980, Clarke & Glander 1984, Glander 1992. Una vez que alcanzan las edades juveniles, esta tendencia de mayor mortalidad de los machos con respecto a las hembras al parecer se mantiene (Glander 1980, Clarke & Glander 1984.…”

Population viability of Alouatta palliata (Primates: Atelidae) and Cebus capucinus (Primates: Cebidae) at Refugio de Vida Silvestre Privado Nogal, Sarapiquí, Heredia, Costa Rica. Habitat destruction may cause wildlife population fragmentation and is considered an important factor in small population species extinction. As wildlife populations become smaller, threats to their stability and persistence arise as a result of demographic, environmental and genetic stochastic factors. The aim of this work was to study the effects of population fragmentation on the long term viability of Alouatta palliata and Cebus capucinus populations, at Refugio de Vida Silvestre Privado Nogal, Sarapiquí (RVSPN), Heredia. For this we used the computer software VORTEX to run a population viability analysis (PVA) for both species. The input data of the PVA were taken from the demography structure of the RVSPN, literature sources from the species and from PVA related papers. We evaluated two sets of scenarios: small fragmented populations to reflect the population current state, and one larger and continuous population, to reflect the effect of reforestation actions followed by RVSPN to connect forest fragments. Results suggest that both A. palliata and C. capucinus can survive in isolated forest fragments. However, if different factors as inbreeding depression, catastrophes or habitat loss were incorporated to the scenarios, the small fragmented populations become unstable and the risk of extinction increased for both species. Continuous and larger populations were more robust against the threats incorporated in the scenarios when compared to the current situation of smaller and fragmented populations. The best management option for both species would be to continue reforestation efforts in the area to connect forest fragments, with the result of larger and continuous populations of both species. It is important to continue the observation of both species populations, and to promote a habitat management to reduce the negative effects of stochastic environmental events. Rev. Biol.

Determinants of female dispersal in Thomas langurs

Female dispersal occurs in a number of primate species. It may be related to: avoidance of inbreeding, reduction in food competition, reduction of predation risk, or avoidance of infanticide in combination with mate choice. Female dispersal was studied for a 5‐year period in a wild population of Thomas langurs (Presbytis thomasi) that lived in one‐male multi‐female groups. Juvenile and adult individuals of both sexes were seen to disperse. Females appeared to transfer unhindered between groups, mostly from a larger group to a recently formed smaller one. They transferred without their infants and when not pregnant, and seemed to transfer preferentially during periods when extra‐group males were harassing their group. During these inter‐group encounters extra‐group males seemed to try to commit infanticide. Thus, the timing of female transfer was probably closely linked to infanticide avoidance. Moreover, females seemed to transfer when the resident male of their group was no longer a good protector. The observations in the present study suggest that females transferred to reduce the risk of infanticide. Female dispersal may have another ultimate advantage as well, namely inbreeding avoidance. Due to the dispersal of both females and males the social organization of Thomas langurs was rather fluid. New groups were formed when females joined a male; male takeovers were not observed. Bisexual groups had only a limited life span, because all adult females of a bisexual group could emigrate. This pattern of unhindered female dispersal affects male reproductive strategies, and in particular it might lead to infanticidal behavior during inter‐group encounters. Am. J.
