However, the magnitude of these changes differs substantially. <i>Pelophylax shqipericus</i> is predicted to undergo more pronounced range contraction and fragmentation, whereas <i>P. epeiroticus</i> shows relatively higher spatial persistence, with suitable areas remaining primarily in lowland coastal regions. Lineage-level analyses reveal uneven patterns of vulnerability, with greater losses generally affecting phylogenetic lineages occupying more restricted or environmentally sensitive parts of the range.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Main Conclusions</h3>\u0000 \u0000 <p>Regardless of the differences in their realized bioclimatic niches, both species respond in a similar direction to projected climate change. This suggests that shared climatic constraints outweigh niche differentiation in shaping future distributions. However, differences in the magnitude of response highlight species-specific and lineage-specific sensitivity to environmental change. These findings emphasize the importance of incorporating intraspecific diversity into climate vulnerability assessments and conservation planning in biodiversity hotspots.</p>\u0000 </section>\u0000 </div>","PeriodicalId":51018,"journal":{"name":"Diversity and Distributions","volume":"32 9","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ddi.70246","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148823267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
