Abstract
Los modelos de distribución de especies basados en un sistema de información geográfica son herramientas útiles para predecir la distribución potencial de las especies y ayudar a tomar decisiones tentativas en la conservación. Actualmente existen varios modelos que tienden a predecir distribuciones significativamente distintas. El objetivo de este estudio es comparar la eficiencia y exactitud de cuatro modelos comúnmente utilizados por biólogos (BIOCLIM, DOMAIN, GARP y regresión logística) en la predicción de la distribución potencial de tres especies de vida silvestre en Bolivia. El modelo DOMAIN, que utiliza el índice de similitud, mostró el mejor rendimiento. La predicción tiende a ser mejor para las especies especialistas de hábitat que para las generalistas.

The objective of this study is to compare the efficiency and accuracy of four commonly used species distribution models (BIOCLIM, DOMAIN, GARP, and logistic regression) to predict the distribution of three wildlife species in Bolivia. The model DOMAIN that uses a similarity index showed the best performance. The prediction tends to be better for habitat specialist species than to generalists.
