1Predicting the impact of climate change on the distribution of two threatened Himalayan medicinal plants of Liliaceae in Nepal显示文摘Predicting the potential distribution of medicinal plants in response to climate change is essential for their conservation and management. Contributing to the management program, this study aimed to predict the distribution of two threatened medicinal plants, Fritillaria cirrhosa and Lilium nepalense. The location of focal species gathered from herbarium specimen housed in different herbaria and online databases were geo-referenced and checked for spatial autocorrelation. The predictive environmental variables were selected, and MaxE nt software was used to model the current and future distributions of focal species. Four Representative Concentration Pathway(RCP) trajectories of the BCC-CSM1.1 model were used as the future(2050) projection layer. The MaxEnt modelling delineated the potential distribution of F. cirrhosa and L. nepalense. The current suitability is projected towards Central and Eastern Hilly/Mountainous regions. Both species gainmaximum suitability in RCP 4.5 which decline towards other trajectories for L. nepalense. Overall, both the focal species shift towards the north-west, losing their potential habitat in hilly and lower mountainous regions by 2050 across all trajectories. Our results highlight the impact of future climate change on two threatened and valuable species. The results can be further useful to initiate farming of these medicinally and economically important species based on climatically suitable zone and for designing a germplasm conservation strategy.RANA Santosh Kumar RANA Hum Kala GHIMIRE Suresh Kulllar SHRESTHA Krishna Kumar RANJITKAR Sailesh 2017Journal of Mountain Science2017,14,3:5
2Using leaf area index(LAI) to assess vegetation response to drought in Yunnan province of China显示文摘Climatic extremes such as drought have becoming a severe climate-related problem in many regions all over the world that can induce anomalies in vegetation condition. Growth and CO2 uptake by plants are constrained to a large extent by drought.Therefore, it is important to understand the spatial and temporal responses of vegetation to drought across the various land cover types and different regions. Leaf area index(LAI) derived from Global Land Surface Satellite(GLASS) data was used to evaluate the response of vegetation to drought occurrence across Yunnan Province, China(2001-2010). The meteorological drought was assessed based on Standardized Precipitation Index(SPI)values. Pearson's correlation coefficients between LAI and SPI were examined across several timescales within six sub-regions of the Yunnan. Further, the drought-prone area was identified based on LAI anomaly values. Lag and cumulative effects of lack of precipitation on vegetation were evident, with significant correlations found using 3-, 6-, 9-and 12-month timescale. We found 9-month timescale has higher correlations compared to another timescale.Approximately 29.4% of Yunnan's area was classified as drought-prone area, based on the LAI anomaly values. Most of this drought-prone area was distributed in the mountainous region of Yunnan.From the research, it is evident that GLASS LAI can be effectively used as an indicator for assessing drought conditions and it provide valuable information for drought risk defense and preparedness.Kwangchol KIM WANG Ming-cheng Sailesh RANJITKAR LIU Su-hong XU Jian-chu Robert J.ZOMER 2017Journal of Mountain Science2017,14,9:4
3Current re-vegetation patterns and restoration issues in degraded geological phosphorus-rich mountain areas:A synthetic analysis of Central Yunnan, SW China显示文摘China has the largest area of inland geological phosphorus-rich(GPR) mountains in the world, where vegetation restoration is key to safeguarding the environment. We reviewed the published literature and collected new data in order to analyze re-vegetation patterns and the status of plant communities in central Yunnan. The aim of our analysis was to suggest future improvements to restoration strategies in GPR mountain regions. Our results showed that spontaneous recovery was the most widespread type of restoration. N-fixing species such as Coriaria nepalensis and Alnus nepalensis play a vital role in succession. In the past, monoculture tree plantation was the primary method used in afforestation activities in central Yunnan; in recent years however, several different methods of restoration have been introduced including the use of agroforestry systems. For practical restoration, we found that spontaneous recovery was capable of delivering the best results, but that during its early stages, restoration results were affected by several factors including erosion risk, the origin of propagates and environmental variation. In contrast, methods employing human-made communities performed better in their early stages, but were constrained by higher costs and vulnerability to degradation and erosion. The use of N-fixing species such as A. nepalensis and Acacia mearnsii in plantations were unsuccessful in restoring full ecosystem functions. The success of restoration activities in GPR mountain regions could be improved through the following measures:(1) developing a better understanding of the respective advantages and disadvantages of current natural and human-engineered restoration approaches;(2) elucidating the feedback mechanism between phosphorus-rich soil and species selected for restoration, especially N-fixing species;(3) introducing market incentives aimed at encouraging specific restoration activities such as agroforestry, and improving the industry value chain.Kai Yan Sailesh Ranjitkar Deli Zhai Yunju Li Jianchu Xu Bo Li Yang Lu 2017Plant Diversity2017,39,3:2
4扁枝槲寄生在茶树群落中分布的影响因子显示文摘基于单数茶树与样方尺度对影响扁枝槲寄生分布的因子进行回归模拟分析。结果表明:1)扁枝槲寄生的平均寄生株率达40%,株高频度分布为生态分布,分支数为左偏正态分布,常分布在树高的1/3-3/4处;扁枝槲寄生的分布对茶树因子的依赖程度高于环境因子。2)基于单株茶树尺度,影响扁枝槲寄生分布的因子大小顺序为:冠幅〉地径〉树高〉枝下高〉苔藓/地衣覆盖率。具有较大冠幅、地径≥11 cm、树高≥3.1 m、枝下高在23-55 cm且苔藓覆盖率较高的茶树上寄生较多。3)基于群落样方尺度,影响扁枝槲寄生分布的环境因子大小顺序为:海拔〉坡向〉郁闭度〉坡度。扁枝槲寄生在调查地区主要分布海拔1 420 m以上,山顶或山谷并无分布,西北、东南坡及郁闭度高的环境下更适合生长,坡度越大越有利于其生长。4)光照、水分是影响扁枝槲寄生的主导环境因子,寄主群落因子导致了光照、水分的再分配,从而影响着扁枝槲寄生在茶树上的分布位置。王青 张媛 陈剑 Sailesh Ranjitkar 沈立新 2015北京林业大学学报2015,37,10:2

6Nutrient value of wild fodder species and the implications for improving the diet of mithun (Bos frontalis) in Dulongjiang area, Yunnan Province, China显示文摘Wild fodder plants are valuable because they provide an important livestock feed resource globally,especially for smallholder farmers,and have important roles in natural resource management.In-depth knowledge of wild forage plants can motivate local people for feed resource and habitat conservation of threatened herbivores such as Mithun(Bos frontalis).Mithun occur in small patches in the mountains of Dulongjiang,nearby villagers domesticated this animal but left animal to freely graze in the mountains.Many fodder plants occur in these mountains,however,little is known about their nutritional value.We conducted an ethnobotanical survey to document important wild fodder plants consumed by mithun in the Dulongjiang Township.The nutritional content of 21 highly mentioned wild fodder plants in an ethnobotanical survey was examined.Laboratory analysis showed that Fagopyrum dibotrys were the fodder species with the highest crude protein(CP)content(26.89%),followed by Polygonum molle(21.88%)and Hydrangea longipes(21.12%).Synthesis of relative feed value index and grey relational grade,P.molle,H.longipes and Tetrastigma obtectum were ranked the top three nutritional fodders.There was a significant difference between 21 species on their in vitro digestibility and the most highly digestible fodder species was Elatostema hookerianum.Linear model analysis on relationship between frequency of citation of 21 wild forage plants by local farmers and their nutrient composition showed that the frequency was significantly positively correlated with the nutritional value of the feed(R2?0.28,P<0.05).We concluded that these species have high nutritional values to improve mithun production in integrated crop-livestock systems.Fodder species or mixtures of species with useful nutritional characters could be cultivated to improve livestock productivity,habitat conservation including that of mithun and wild forage resource management.Yanfei Geng Sailesh Ranjitkar Qiaoshun Yan Zhijun He Baqi Su Shengtao Gao Junli Niu Dengpan Bu Jianchu Xu 2020Plant Diversity2020,42,6:2
