However, future projections under Shared Socioeconomic Pathway (SSP) scenarios suggest a general contraction of suitable habitats. Notably, the species is projected to shift not only toward higher elevations but also toward southeastern coastal regions of China. Under high-emission scenarios such as SSP370, intensified climate variability and winter warming (Bio6) are expected to exacerbate habitat fragmentation, substantially increasing extinction risk.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Accordingly, Conservation priorities should include the existing core range in the Sichuan-Guizhou-Yunnan region, as well as potential future climate refuges identified along the Guizhou-Hunan border.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpls.2026.1901185","type":"journal-article","created":{"date-parts":[[2026,8,31]],"date-time":"2026-08-31T15:37:39Z","timestamp":1788190659000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["A comprehensive assessment of climate and topographic changes to identify conservation gaps for the critically endangered species Coptis teeta Wall in southwest China"],"prefix":"10.3389","volume":"17","author":[{"given":"Ran","family":"Li","sequence":"first","affiliation":[{"name":"College of Geography and Planning, Chengdu University of Technology","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaobo","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Geography and Planning, Chengdu University of Technology","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wende","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Geography and Planning, Chengdu University of Technology","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuelin","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Geography and Planning, Chengdu University of Technology","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yigui","family":"Zhou","sequence":"additional","affiliation":[{"name":"Sichuan Forestry and Grassland Survey and Planning Institute","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiali","family":"Zhou","sequence":"additional","affiliation":[{"name":"College of Geography and Planning, Chengdu University of Technology","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kening","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Geography and Planning, Chengdu University of Technology","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuan","family":"Qi","sequence":"additional","affiliation":[{"name":"College of Geography and Planning, Chengdu University of Technology","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhongxuan","family":"Huang","sequence":"additional","affiliation":[{"name":"College of Geography and Planning, Chengdu University of Technology","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,8,31]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"95","DOI":"10.1111\/j.1752-4571.2007.00013.x","article-title":"Adaptation, migration or extirpation: climate change outcomes for tree populations","volume":"1","author":"Aitken","year":"2008","journal-title":"Evol.
