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.

The study of self-medication in non-human primates sheds new light on the complex interactions of animal, plant and parasite. A variety of non-nutritional plant secondary compounds and nutrient-poor bark is found in the primate diet, but little is yet known about the possible medicinal consequences of their ingestion. Recent studies of the African great apes support a hypothesis in progress that the non-nutritional ingestion of certain plant species aid in the control of parasite infection and provide relief from related gastrointestinal upsets. Detailed behavioral, pharmacological and parasitological investigations of two such behaviors, bitter pith chewing and leaf swallowing, have been conducted on three East African chimpanzee populations, but they are now known to occur widely among all chimpanzee subspecies, as well as bonobos and lowland gorillas. For both bitter pith chewing and leaf swallowing, selection of the same plant species tends to occur among neighboring groups of same ape species. These local cultural traditions of plant selection may be transmitted when females of the same species transfer into non-natal groups. However, selection of the same plant species or species of related plant genera by two sympatric ape species or between regional populations of great ape subspecies strongly suggests a common criteria of medicinal plant selection. This and the intriguing observation that the same medicinal plant is selected by apes and humans with similar illnesses provide insight into the evolution of medicinal behavior in modern humans and the possible nature of self-medication in early hominids. The occurrence of these and other specific self-medicative behaviors, such as fur rubbing and geophagy, in primates and other animal taxa suggest the existence of an underlying mechanism for the recognition and use of plants and soils with common medicinal or functional properties.
