Additionally, national nature reserves parks were overlaid with priority conservation zones having irreplaceability values ranging from 80 100 identify gaps. The findings indicate that found southern Yunnan Province, which exhibits highest concentration. high expected shrink 0.62×104km2 under future climate scenarios. Northern latitudes higher altitudes offer better habitats for majority species. With intensification change, it is anticipated this migration will exceed 150 km.

Enhancing the decay resistance of Populus tomentosa wood through environmentally friendly methods is crucial for improving its durability and market competitiveness. Lignified twigs (LT), typically unsuitable as timber due to their small diameter, are rich in lignin, which degrades during thermal induction produce antifungal organic compounds. In this context, objective study was develop a lignified twig preservative (LTP) by from LT Actinidia chinensis var. Jinyang. The activity LTP under varying conditions analyzed, along with chemical composition. Enzyme activity, cell membrane integrity, respiratory metabolism fungi treated were examined elucidate mechanisms. Additionally, LTP-treated evaluated. Results revealed that produced N2 at 220 °C exhibited robust against Trametes versicolor Gloeophyllum trabeum, attributed phenolic compounds such syringaldehyde, syringone, vanillin, vanillone. inhibited fungal cellulases, hemicellulases, ligninases 30%–60%, disrupted functionality, suppressed metabolism. Poplar demonstrated significantly enhanced (mass loss < 10%). This thermal-induced feedback pattern shows great potential preservation.

Camphora longepaniculata is an endangered evergreen tree listed as National Class II Protected Tree Species in China, highly valued for its medicinal and economic importance. Currently, research on this species has primarily focused pharmaceutical properties, while potential distribution responses to climate change remain insufficiently explored. In study, 36 valid occurrence records 11 environmental variables were utilized predict assess response future scenarios. The MaxEnt model revealed that the current of C. largely aligns with predicted suitable habitats, primary range located Sichuan Province. Furthermore, identified habitats be predominantly concentrated Shaanxi Provinces under change. Among variables, annual precipitation (bio12), minimum temperature coldest month (bio6), elevation (dem) most influential, collectively contributing over 70% model’s predictive accuracy. Future projections compared suggest a northward expansion longepaniculata, although Province core habitat Kernel density analysis points indicated largest concentration near Basin, reinforcing importance region stronghold species. Based results kernel analysis, situ conservation, artificial cultivation, establishment wild protected areas local germplasm banks are recommended stable, such parts Yunnan Guizhou Provinces.

ABSTRACT Climate change is widely recognized as a major threat to biodiversity and critical factor contributing the decline in species populations. However, it remains uncertain whether from continental island environments, especially endangered ones, will respond similarly or differently climate change. The strategies employed by these cope with change, corresponding conservation management approaches, remain poorly understood. In this study, we ecological niche models project future shifts distribution patterns of two sister species, Trigonobalanus doichangensis T. vericillata , which are distributed across regions tropical Asia. We analyzed potential changes their under four different scenarios for 2050s 2070s. Our results indicate that temperature significant driver whereas precipitation predominantly influences . Moreover, found range likely exceed suggesting may have stronger capacity adapting recommend areas be established maintain habitat stability most affected A comprehensive assessment status both also essential. Overall, study underscores distinct responses thereby enhancing our understanding adaptive informing targeted efforts.

As a Chinese endemic species with dual medicinal–industrial importance, Eucommia ulmoides faces habitat challenges under climate change. Using 21 bioclimatic variables and 704 occurrence records, we modeled current future (2021–2100) distributions via MaxEnt 3.4.4 ArcGIS 10.8. The results indicate the following: (1) optimal habitats cluster in mid-elevation valleys of Daba–Wuling Mountains (Guizhou–Chongqing core); (2) SSP5-8.5 projections suggest 19.2% reduction high-suitability areas by 2081–2100 versus SSP1-2.6; (3) distribution centroids migrate southward both scenarios. Our multi-temporal analysis provides actionable intelligence for ex situ conservation agroforestry planning.

However, the current distribution future of these plants their environmental driving factors under climate change are not well known. Here, we focus on Lepidium meyenii, a medicinal herb native to high-altitude regions Andes Mountains South America, which may face habitat contraction potential population decline due changing conditions. We integrate species data with random forest model simulate habitats L. meyenii across time identify key drivers. find that most significant variables impact include elevation, temperature annual range (bio7), mean diurnal (bio2). Since Last Glacial Maximum, western America consistently offered suitable for meyenii. In contrast, suitability Tibetan Plateau (TP) varied over time, futurer TP become area biodiversity conservation. This study will enhance our understanding patterns response change, contributes conservation efforts, establishment protected areas, sustainable management as biological resources.
