“…To date the only published study of genetic diversity in S. o. citrinellus was based on a small sample (N = 8) from Manuel Antonio National Park (MANP) [39], which is the smallest national park in Costa Rica and the only protected area within the range of S. o. citrinellus . The study concluded that S. oerstedii have moderate to high genetic diversity compared to the three other primate species in Costa Rica ( Alouatta palliata, Ateles geoffroyi, and Cebus capucinus ).…”

Landscape genetic studies offer a fine-scale understanding of how habitat heterogeneity influences population genetic structure. We examined population genetic structure and conducted a landscape genetic analysis for the endangered Central American Squirrel Monkey (Saimiri oerstedii) that lives in the fragmented, human-modified habitats of the Central Pacific region of Costa Rica. We analyzed non-invasively collected fecal samples from 244 individuals from 14 groups for 16 microsatellite markers. We found two geographically separate genetic clusters in the Central Pacific region with evidence of recent gene flow among them. We also found significant differentiation among groups of S. o. citrinellus using pairwise FST comparisons. These groups are in fragments of secondary forest separated by unsuitable “matrix” habitats such as cattle pasture, commercial African oil palm plantations, and human residential areas. We used an individual-based landscape genetic approach to measure spatial patterns of genetic variance while taking into account landscape heterogeneity. We found that large, commercial oil palm plantations represent moderate barriers to gene flow between populations, but cattle pastures, rivers, and residential areas do not. However, the influence of oil palm plantations on genetic variance was diminished when we restricted analyses to within population pairs, suggesting that their effect is scale-dependent and manifests during longer dispersal events among populations. We show that when landscape genetic methods are applied rigorously and at the right scale, they are sensitive enough to track population processes even in species with long, overlapping generations such as primates. Thus landscape genetic approaches are extremely valuable for the conservation management of a diverse array of endangered species in heterogeneous, human-modified habitats. Our results also stress the importance of explicitly considering the heterogeneity of matrix habitats in landscape genetic studies, instead of assuming that all matrix habitats have a uniform effect on population genetic processes.

“…En Costa Rica, como en muchos de los países mencionados en ese informe, existe una tendencia a la disminución en el número de individuos y especies de animales silvestres, en las que se incluyen los monos con que cuenta este país a saber: mono congo o aullador (Alouatta palliata Gray, 1849), carablanca (Cebus capucinus, Linnaeus, 1758), tití o ardilla (Saimiri oerstedii, Reinhardt, 1872) y colorado o araña (Ateles geoffroyi Kuhl, 1820) (Villalobos et al 2004, Zaldívar et al 2004). La creación de áreas protegidas ha contribuido a la conservación de estas especies, mientras que la destrucción del habitat y la cacería clandestina, son casi siempre los factores responsables de la disminución del número de individuos en las poblaciones.…”

Intestinal parasites in howler monkeys Alouatta palliata (Primates: Cebidae) of Costa Rica. Fecal samples of 102 howler monkeys (Alouatta palliata) from several sites of Costa Rica were studied for intestinal parasites. The zones studied were: Central Valley (San Ramón, Alajuela), Central Pacific (Chomes and Manuel Antonio National Park, Puntarenas), North Pacific (Palo Verde Park and Playa Potrero, Guanacaste), Chira Island in the Nicoya Gulf and Caribean area (Cahuita, Limón). Animals were anesthetized with dards containing Telazol in order to collect the fecal material; some monkeys defecated spontaneously and others by direct stimulation. Samples were studied in saline solution (0.85%) and a Iodine solution, or stained with Haematoxylin. The material was also cultured in Dobell culture medium to determine the presence of amoeba and flagellates. Strongyloides, Controrchis, Trypanoxyuris genera were found in 3.4% of the samples. In addition 16.7% to 80% of the animals showed protozoa infection with Endolimax, Entamoeba, Trichomonas and Giardia. It is discussed the relationships of parasite infection with environmental conditions, animal population and human presence, specially in the monkey conservation programs point of view. Rev. Biol. Trop. 53(3-4): 437-445. Epub 2005 Oct 3.

“…With so little undisturbed forest left in Central America, native species are forced to adjust to habitat changes or face extinction. Primates that once inhabited areas that are now cities or farms have faced population declines [Fedigan & Jack, 2001] and, like the tropical forests they inhabit, these primates have become a conservation concern [Zaldivar et al, 2004].…”
