| 要旨本文 | Global warming poses a severe threat to cold-temperate and alpine ecosystems. Betula ermanii, found in the mountainous regions of Hokkaido, Honshu, and Shikoku in Japan, was the subject of this study. 11 range-wide provenance trials were conducted across Japan, incorporating 11 natural populations, including genetically unique southern edge and alpine populations. Models were constructed to evaluate survival and productivity under elevated temperatures with variations in annual precipitation, predicting the future potential of range edge and central populations under two climate scenarios. Results indicate heightened susceptibility in the alpine population, with the southern-edge population also experiencing a significant decline compared to normative populations. The study underscores the urgent need for targeted conservation strategies for at-risk edge populations, offering valuable insights for resilient forest management and conservation of vulnerable populations. |
