Understanding species response to climate change is essential for the conservation and utilization of resources under rapid in future. In this study, present future suitable distribution range Keteleeria davidiana, a tertiary relict gymnosperm, was predicted based on maximum entropy model (MaxEnt). A total 158 occurrence records were collected after removing duplicated records. Six low-correlation variables used predict distributions. The three key factors that affect K. davidiana temperature seasonality (34.96%), mean coldest quarter (28.30%) precipitation (13.58%). most zone between 377.4 843.4. highly area located mountainous regions central southeast China, which accounted 13.39% whole study area. With warming future, estimated decrease by 35% (SSP1-2.6 scenario) or 85% (SSP5-8.5 scenario). This has provided sufficient scientific basis situ ex davidiana.

Understanding ecological niche evolution patterns is crucial for elucidating biogeographic history and guiding biodiversity conservation. Taxus a Tertiary relict gymnosperm with 11 lineages mainly distributed across East Asia, spanning from tropical to subarctic regions. However, the spatiotemporal dynamics of its roles geographical factors in lineage diversification, remain unclear. Using occurrence records, environmental data, reconstructed phylogenies, we employed ensemble models (eENMs), principle components analysis (PCA-env), phyloclimatic modeling analyze similarity among lineages. Based on Bayesian trees distribution characteristics, classified eleven into four clades: Northern (T. cuspidata), Central chinensis, T. qinlingensis, Emei type), Western wallichiana, florinii, contorta), Southern calcicola, phytonii, mairei, Huangshan type). Orogenic activities climate changes Tibetan Plateau since Late Miocene likely facilitated local adaptation ancestral populations China, Hengduan Mountains, Yunnan-Guizhou Plateau, driving their expansion diversification towards west south. Key variables, including extreme temperature, temperature precipitation variability, light, altitude, were identified as major drivers current divergence. Both conservatism divergence observed, early followed by recent The clade exhibits high heat moisture tolerance, suggesting an adaptive shift, while clades retain drought cold displaying significant phylogenetic (PNC). We recommend prioritizing conservation which highest PNC level, particularly Qinling, Daba, Taihang are highly degraded vulnerable future fluctuations.

ABSTRACT Global climate change may represent a significant threat to the distribution and quality of medicinal plants, altering cultivation areas compromising medical materials. Platycodon grandiflorus , traditional Chinese herb, has millennia‐long culinary use history in East Asia. Given its escalating demand, accurately evaluating changes under different scenarios predicting potential are imperative for ensuring conservation sustainable utilization. By integrating MaxEnt with ArcGIS, this study advances previous approaches by incorporating historical, present, future data model dynamics P. across China. The results indicated: (1) species' strongly correlates environmental variables, particularly bio13, prec07, prec09, tmin07, whose cumulative value percent contribution was 78.5%; (2) centroids geographic during LIG, LGM, MH periods were situated further westward compared present distribution, substantial contraction observed highly suitable habitats throughout these historical periods; (3) Under climatic conditions, overall habitat encompasses 4,185,964 km 2 constituting one‐third expanse, predominantly concentrated central, southern, northeastern China; (4) Future predict that total will expand varying degrees (7% increase on average), albeit reductions (3% decrease average); (5) is likely move toward higher latitudes due changes. Our findings fill critical knowledge gap quantifying impact . These offer crucial insights developing effective strategies, promoting utilization, establishing standardized protocols resources.

Abstract Background The taxonomy of Taxus Linn. remains controversial due to its continuous phenotypic variation and unstable topology, thus adversely affecting the formulation scientific conservation strategies for this genus. Recently, a new ecotype, known as Qinling type , is mainly distributed in Mountains belongs monophyletic group. Here, we employed multiple methods including leaf phenotype comparison (leaf shapes microstructure), DNA barcoding identification (ITS + trn L -trn F rbc L), niche analysis ascertain taxonomic status . Results Multiple comparisons revealed significant differences morphological characters (length, width, length/width ratio) among other species. Leaf anatomical indicated that only T. cuspidata had no papilla under midvein or tannins epicuticle. Phylogenetic belonged Moreover, formed relatively independent niche, it was around Mountains, Ta-pa Taihang situated at an elevation below 1500 m. Conclusions Four characters, namely curvature, margin taper, papillation on midvein, edges were put forward primary indexes distinguishing ecotype Qingling represented evolutionary lineage unique ecological niche. Therefore, suggested should be treated novel species named qinlingensis Y. F. Wen & X. Wu, sp. nov.
