Abstract:

Species distribution is critical for developing effective conservation measures. The potential geographic distribution of the white-lipped deer (Przewalskium albirostris), which is endemic to the Qinghai- Tibetan Plateau, was delineated using the Maximum Entropy (MaxEnt) model with 97 occurrence records and 7 environmental variables. The species occurrences were collected from literature and field investigations. Our results showed that the potential range of the white-lipped deer included the eastern part of the Qinghai-Tibetan Plateau and the potential habitat spread from one core region to neighboring regions among Tibet, Qinghai, and Sichuan provinces. The Jackknife test indicated that the topographic variable, temperature seasonality, and annual precipitation were the most important predictive factors for the model, while the human activity variable made a relatively small contribution. The current distribution and status of the white-lipped deer on the Qinghai-Tibetan Plateau is unclear and we suggest further research is needed on the species.
