The smoke tree (Cotinus coggygria Scop.) is a woody species mainly distributed in the Mediterranean region and East Asia, known for its high ecological ornamental value. Investigation of changes suitable habitats under different conditions can provide valuable insights with implications predicting distribution C. coggygria. In this study, we employed MaxEnt model to simulate current, historical, future habitat using records environmental variables. results indicated that climatic variables had much stronger impact on compared soil topographic variables, bio11 (mean temperature coldest quarter) bio12 (annual precipitation) played particularly important roles determining habitat. core exhibited an Asian-Tethyan disjunction. During glacial period (Last Glacial Maximum), Europe was concentrated refugia southern Europe; range substantially smaller during than interglacial periods (mid-Holocene). contrast, Asia survived regions similar those period. Future climate change led gradual northward expansion coggygria, area larger Asia. There were significant differences among four scenarios Europe, minimal variation Our findings into contrasting effects European Asian populations which enhances our understanding Eurasian discontinuous distributions.

Abstract Coping with increasing global temperatures due to climate change may be especially challenging for trees long generation times as changes might happen too quickly successful adaptation. Juniperus przewalskii Komarov is an arid tolerant key species of forest ecosystems on the northeastern Qinghai–Tibet Plateau. Target capture sequencing was utilized survey genetic variation and population structure, infer evolutionary history this by analyzing 170 individuals from 23 populations. This approach provided valuable information how local adaptation influences background species, well potential predictions regarding species' response change. Our results revealed a new fine‐scale structure high levels diversity adaptations despite gene flow. Redundancy analysis showed that contributed most J. . Analysis gradient risk nonadaptedness indicated that, variables examined majority locations sampled, it improbable will need significant alterations in allele frequencies endure forecasted shifts. We also identified at‐risk populations preservation numerous candidate genes upcoming The significance combining environmental forecast resilience tree warming underscored our results, particularly areas susceptible fluctuations.
