    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.

    Using open sources program and online applications to support environmental monitoring

    Field survey is an important step in monitoring environmental quality. Until now, there are many difficulties in field study leading to low efficiency due to inadequate equipments. Two of them can be named: - Coordinates and photos of each surveyed point have not been synchronized professionally. - After being synchronized, pictures and surveyed routes need to be shown in public map (e.g. Google Map), open source software (e.g. QGIS) and software that use cloud computing (e.g. Google Earth) to be followed and used for future surveys. In order to solve these two problems, the authors have conducted survey and used GpicSync software to synchronize coordinates and pictures basing on time variable (i.e. the time data was recorded on GPS and the time photos were taken). The study has been implemented in Vinh Phuc province which is located in Northern Vietnam. As a result, synchronizing coordinators and photos becomes faster and simpler. On the other hand, the results of synchronization could be shown on Google Earth, Google Maps, as well as other open source software. In addition, with other environmental information, synchronization also helped with environmental monitoring, investigation, survey, and samples collection.
