“…Altitude was considered to be the main factor affecting the distribution of J. subtriplinerve. This finding aligns with previous studies, which highlighted the critical role of altitude in plant species distribution (Chen et al, 2022, Wani et al, 2023. The rationale is that variations in altitude directly affect other environmental parameters, including temperature, precipitation, vegetation cover, and soil characteristics.…”

Jasminum subtriplinerve, a rare and valuable medicinal plant, is facing the problem of habitat loss. This study was conducted to determine the influences of environmental factors on the distribution and identify habitat suitability areas for this species in Central Vietnam. Based on the 19 bioclimatic, 10 soil properties, 3 topographic variables and 86 observed locations, we used Correlation Analysis processing, follow by the Maximum entropy (MaxEnt) algorithm was applied to predict the spatial potential distribution of J. subtriplinerve. Using the MaxEnt model for analyzing the J. subtriplinerve distribution showed a good performance (AUC testing = 0.821 and AUC training = 0.887). The most influential factors on J. subtriplinerve distribution were Altitude (49.2%), Mean diurnal range (10.6%), Isothermality (6.9%), Bulk density (5.2%), Normalized difference vegetation index (4.7%) and Proportion of sand particles (4.6%). In addition, the model showed that very high and high potential habitat areas of J. subtriplinerve occupied 3.17% (658.88 km2) and 8.95% (1,858.56 km2) of the studied site, distributed in the midland and low mountainous areas, the most suitable Altitude ranged from 8.1 to 138.7 m. Meanwhile, 15.17%, 18.10% and 54.60% of the studied site were nominated as moderate (3,148.93 km2) low (3,758.10 km2), and very low (11,334.17 km2) potential habitat areas, respectively. This study comprehensively evaluated factors affecting habitat suitability, therefore, these results provide an understanding of the bioecological distribution of J. subtriplinerve guiding the identification of optimal areas for cultivation and conservation.

The present study attempts to comprehensively study the floristic elements of Gulmarg Wildlife Sanctuary (GWLS), Kashmir Himalaya. During the present study 364 species of vascular plants belonging to 227 genera and 74 families were recorded from the sanctuary. A total of 18 communities (10 within forest and 8 within alpine zone) were identified. Forest zone of the sanctuary was represented by shady moist, dry, bouldery, rocky, riverine and exposed habitats; whereas the alpine zone was represented by bouldery, riverine and moist and exposed habitats. Of the total 364 reported plant species, 161 species were native to Himalayan region and the remaining i.e. 203 species were non‐natives. Out the total 161 native plant species, 82 were endemic to the Himalayan region. Further, 22 plant species were having threatened status in Jammu and Kashmir. Major threats to biodiversity within the sanctuary include overexploitation, habitat degradation, overgrazing, invasive species, human settlements, huge tourism influx and pollution. In the present study, based on the 'conservation priority index' (CPI) of the plant species, 51 plant species were assessed to be threatened in GWLS. Further, maximum CPI of dry and shady moist habitats and Aesculus indica–Pinus wallichiana mixed and Taxus wallichiana–Prunus cornuta–Aesculus indica mixed communities reveals that proper management of these prioritized habitats and communities would help in maintaining the natural ecosystems and conservation of species of the sanctuary. Present study recommends that awareness about the values of biodiversity for sustenance through organization of training workshops, awareness camps need to be created among the local inhabitants as well as visitors. Further, no in‐depth explorations for community characterization of forest and as well as alpine ecosystems of Kashmir Himalaya have been conducted; present study in the GWLS provides a template, which can be replicated in other protected as well as unprotected areas of the Kashmir Himalaya.

Ecosystem stability arises from the interplay of species diversity, environmental conditions, and external disturbances. Understanding the structure of plant communities, interspecific relationships, and community stability in urban ecosystems is fundamental to ecological restoration and community development. This study utilized the karst city of Guiyang as a case study and employed the α diversity index, variance ratio method (VR), χ2‐test, Pearson correlation test, Spearman rank correlation test, M. Godron stability, and canonical correspondence analysis (CCA). The research focused on analyzing the species diversity, interspecific associations, community stability, and environmental factors of lithophytic moss at various elevations (989–1398 m). The findings revealed the presence of 58 species belonging to 27 genera and 13 families of lithophytic moss in the study area. Notably, the Brachytheciaceae and Pottiaceae emerged as dominant, exhibiting a broad ecological range and adaptation mechanisms, thereby playing a crucial role in the ecological environment of rocky desertification. The study observed that the highest species richness and dominance values of lithophytic moss were recorded at the N4 (1296–1398 m) elevation gradient, while the highest species diversity and uniformity values were observed at the N3 (1194–1295 m) elevation gradient, indicating a significant impact of altitude on lithobryophyte species diversity, particularly at middle and high altitudes. The analysis of interspecific associations and stability indicated a predominantly negative overall association within the lithophytic moss community, suggesting an early stage of succession, with weak interspecific associations and correlations among dominant pairs, tending towards relative independence. Only the communities at N2 (1092–1193 m) elevation exhibited stability, while the other communities were in an unstable stage, showing no significant correlation with species diversity. Furthermore, light intensity (182–129300 lux) exerted the greatest influence on community stability. Additionally, air humidity (36.5–52.3%) and altitude (998–1327 m) emerged as the primary environmental factors influencing community distribution, with a close and positive correlation between the two. These results hold significant reference value for promoting the succession and steady development of vegetation in rocky desertification areas and enhancing the conservation and restoration of vegetation community diversity in karst urban ecosystems.
