Betula albosinensis serves as an important constructive and afforestation tree species in mountainous areas. Its suitable habitat quality are highly vulnerable to the climate. However, few studies have centered on shrinkage, expansion, fragmentation of B. forests under climate change. In this study, Random Forest model was employed predict current future trends shrinking expanding albosinensis, while a composite landscape index utilized evaluate habitats albosinensis. The results indicated that for were primarily concentrated vicinities Qinling, Qilian, Hengduan Mountains, situated western China. most influential factor affecting distribution temperature seasonality (Bio4). scenarios, center projected shift towards west higher altitudes. total anticipated expand scenarios SSP370 SSP585 2090s, they expected contract remaining scenarios. Although these areas relatively intact whole, increased with change, highest degree observed scenario 2090s. findings study provide foundation protection montane vegetation, maintenance biodiversity, evaluation species’ fragmentation.

The alpine steppe has an important place in ecosystems, and its distribution pattern is strongly influenced by climate change. In this study, we used “biomod2” “FragStats 4.2” to calculate the migration trends habitat fragmentation of three S. purpurea steppes on western Tibetan Plateau. results study show that Stipa purpurea-Ceratoides compacta steppe, purpurea-Carex moorcroftii montis-everestii are climate, while other variables have less impact. Their main influence factors annual precipitation (Bio12), warmest quarter (Bio18), coldest (Bio19), respectively. effects carbon emissions suitable habitats all significant future scenarios. Continued increases will lead a continuous reduction their areas. These communities bounded 33° N. South boundary, mountain ranges tendency migrate higher elevations southward direction. North northward Climate change reduces community aggregation, leading gradual fragmentation. findings provide scientific basis for conservation Plateau, thereby contributing improvement ecosystem stability species diversity.

ABSTRACT Ephedra intermedia , a medicinally significant plant, is an important component of arid and semi‐arid ecosystems across Central South Asia. This research sought to predict the present future distribution E. by applying ecological niche modeling (ENM) methods. The model incorporated comprehensive bioclimatic edaphic variables species' habitat suitability. results demonstrated high predictive accuracy, highlighting importance temperature seasonality, annual range, soil pH, nitrogen content as key species determinants. current suitability map revealed core areas in Afghanistan, Pakistan, Tajikistan mountain regions. Under climate change scenarios (SSP2‐4.5 SSP5‐8.5) for 2050s 2070s, projected upward northward shift suitable habitats, coupled with notable contraction extent highly areas, particularly under high‐emission SSP5‐8.5 scenario. predicted range shifts reflect sensitivity increasing temperatures changing precipitation patterns. suggests potential loss habitats low‐elevation southern parts its range. Including factors provided novel insights, specifically critical role properties, such pH content, shaping . These findings complement observed scenarios, emphasizing reliance on high‐altitude refugia conditions change. underscore implications conservation planning, suggesting that strategies should prioritize protection these refugial while also considering measures connectivity assisted migration support adaptation shifting environmental conditions.

Xinjiang in China is distinguished by its distinctive regional landscape and high ecological sensitivity. Trollius wildflowers represent a unique iconic element of the mountain flower Xinjiang. However, their populations are predominantly distributed mountainous areas, making them susceptible to climate change. Despite this, impacts change on distribution suitable habitats niche differentiation for have rarely been quantified. Consequently, simulations were conducted using R-optimized MaxEnt model predict habitat wildflowers. This was based occurrence data environmental variables four species (T. altaicus, T. asiaticus, dschungaricus, lilacinus) that exist study area. The simulation over period time, beginning with past glacial extending present, then future (2050s, 2070s, 2090s) under multiple scenarios (SSP1-2.6, SSP3-7.0, SSP5-8.5). enabled measurement breadth differentiation. results demonstrate predictions precisely accurate, AUC values exceeding 0.9.
