Zusammenfassung
Environmental niche modeling has been demonstrating to be a useful tool in conservation planning and be used
widely in recent years. Therefore, many models have been developed for different purposes as well as different
species so far. This paper presents an application of two of them (i.e. BIOCLIM and DOMAIN models) to study the
distribution of Francoi’s langur in Northeastern Vietnam. Surface climate data and distribution data from the
previous surveys were used as model input. The model results represented potential distribution areas of
Trachypithecus francoisi in current climatic condition and predictive areas in some future climatic conditions
according to IPCC climate change scenario. The results also pointed out that the distribution of Francoi’s langur
might be moving to the North and the West under climate change influence. The authors also implemented a
comparison whether BIOCLIM or DOMAIN model is more suitable for modeling the distribution of this specific
species. This study is a continuing effort to apply environmental niche modeling for primate species. The results are
meaningful in supporting scientists and managers to organize field study planning in order to conserve this species.
