Assessing the Impact of Elevation and Seasonality on the Detection of Medium- to Large-Sized Mammals by Camera Traps.

Factors such as elevation, season, and micro-environment may introduce bias and should be evaluated to minimize potential errors. Our findings revealed the significant impacts of altitude and season on the number of cameras and monitoring duration required in camera trap surveys. The optimal strategy for monitoring mammals is to increase the number of cameras and decrease the sampling period at lower elevations, to add more cameras and extend the sampling time during the dry season due to seasonal differences in capture ratio and species richness.

Spatio-Temporal Niche of Sympatric Tufted Deer () and Sambar () Based on Camera Traps in the Gongga Mountain National Nature Reserve, China.

Clarifying the distribution pattern and overlapping relationship of sympatric relative species in the spatio-temporal niche is of great significance to the basic theory of community ecology and integrated management of multi-species habitats in the same landscape. In this study, based on a 9-year dataset (2012-2021) from 493 camera-trap sites in the Gongga Mountain National Nature Reserve, we analyzed the habitat distributions and activity patterns of tufted deer () and sambar (). (1) Combined with 235 and 153 valid presence sites of tufted deer and sambar, the MaxEnt model was used to analyze the distribution of the two species based on 11 ecological factors.
