Abstract:Abstract: Global warming profoundly impacted biodiversity, and wildlife responded to climate change by migrating and dispersing to select habitats suitable for survival and reproduction. As representative ungulate species in China's boreal forest ecosystems, the wapitis (Cervus canadensis) played a critical ecological role in maintaining forest structure and ecosystem stability. The northern Daxing'an Mountains served as an important distribution area for the Northeast Asian subspecies of wapitis (Cervus canadensis xanthopygus). To investigate climate adaptation strategies of wapitis, we conducted an integrated field study during 2023—2024 across five forestry bureaus in the northern Daxing'an Mountains (Xilinji, Tuqiang, Amur, Tahe, and Shibazhan). We combined infrared camera trapping and transect surveys to collect occurrence data, which was used to model habitat suitability using MaxEnt and ArcGIS under current conditions and future climate scenarios (2041—2060 and 2061—2080) across four Shared Socioeconomic Pathways(SSP126、SSP245、SSP370、SSP585). Additionally, we analyzed centroid migration trends and constructed ecological corridors using circuit theory. The results indicated that: (1) The main environmental factors affecting the distribution of wapitis included precipitation of the wettest month (bio13), precipitation of the wettest quarter (bio16), trails, rivers, and slope aspect. (2) Under current climatic condition, the habitat of wapitis was severely fragmented, with a potential suitable habitat area of 4177.38 km2. Among this, the highly suitable habitat area was 948.72 km2, and the low suitable habitat area was 3228.66 km2. (3) Under future climate scenarios, both the highly suitable and low suitable habitat areas of wapitis showed varying degrees of expansion, with a more significant impact on the low suitable habitat. By the period 2061–2080 under the medium development pathway (SSP245) scenario, the area of suitable habitat expanded by up to 803.7 km2. (4) Habitat centroids shifted toward higher elevations in southwestern or southeastern directions, all within Amur Forestry Bureau boundaries, reflecting the topography descended from the south to the north. (5) The area of ecological sources showed an expanding trend, and the locations of corridors changed with the addition of new ecological sources and the direction of migration. Among these, corridor (C15) served as a key corridor connecting the ecological sources of Tahe and Shibazhan Forestry Bureaus. The findings of this study on habitat suitability and corridor construction for wapitis in the northern Daxing'an Mountains under varying climate conditions provided a scientific basis for future habitat restoration and optimal habitat landscapes development, while offering practical guidance and fundamental data to facilitate wapiti population migration and dispersal.
