ABSTRACT
Climate change can have many negative impacts on wildlife species, and species with narrow distributions are more likely to be significantly affected. In this study, we used ecological niche modeling for species (MaxEnt software) as well as species occurrence data and climate variables to assess the impacts of climate change on the distribution of the grey-shanked douc-an endemic and rare primate species of Vietnam. We used climate data at the current time and two future times (2050 and 2070). Climate data were generated for two climate scenarios RCP4.5 and RCP8.5, together with three climate models ACCESS1-0, GFDL-CM3, and MPI-ESM-LR. We predicted that the distribution of the grey-shanked douc would be sharply reduced by the effects of climate change. The species' suitable distribution range in the future tended to shift toward the center of their current range and to higher mountainous areas. A larger suitable area, in particular highly suitable areas to the north and west of its current potential distribution range, would become less suitable or even unsuitable in 2050 and 2070. Kon Cha Rang Nature Reserve and Kon Ka Kinh National Park should be given priority in conservation of the grey-shanked douc because they now support important populations of the species and are in the highly suitable area remaining for the species in the future. The establishment of a new protected area for grey-shanked douc conservation should be considered in Kon Plong District, Kom Tum Province, which will be the center of the species distribution range.
