Resumen
Se estudió la asociación entre la distribución geográfica, algunos rasgos ecológicos, las historias de vida, la diversidad genética y el riesgo de extinción, en primates no humanos de Costa Rica. Se incluyen todas las especies de primates no humanos del país: los monos araña (Ateles geoffroyi), congo (Alouatta palliata), cara blanca (Cebus capucinus), y tití (Saimiri oerstedii). La distribución geográfica se caracterizó utilizando principalmente bases de datos existentes. Se obtuvo información acerca de sus características ecológicas y de historias de vida mediante una revisión bibliográfica. Se estudió su diversidad genética utilizando electroforesis de isoenzimas. El riesgo de extinción se evaluó usando información bibliográfica. Se encontró que las cuatro especies presentaban variación en todos estos rasgos. Con estos datos, se realizó una correlación de Pearson entre el riesgo de extinción y las variables indicadoras de la distribución geográfica, los rasgos ecológicos, las historias de vida y la diversidad genética, para aquellas especies con una amplia distribución geográfica. Se encontró una asociación entre el riesgo de extinción y la natalidad y la tasa de crecimiento poblacional; las especies con menor natalidad y menor tasa de crecimiento poblacional tenían mayor riesgo de extinción. Se encontró una asociación positiva entre la diversidad genética y el riesgo de extinción; las especies con mayor diversidad genética tenían mayor riesgo de extinción. Se discute la importancia de estos rasgos para la conservación de estas especiesCitas
