| 1 | Strong link between large tropical volcanic eruptions and severe droughts prior to monsoon in the central Himalayas revealed by tree-ring records显示文摘Large tropical volcanic eruptions can cause short-term global cooling. However, little is known whether large tropical volcanic eruptions, like the one in Tambora/Indonesia in 1815, cause regional hydroclimatic anomalies. Using a tree-ring network of precisely dated Himalayan birch in the central Himalayas, we reconstructed variations in the regional pre-monsoon precipitation back to 1650 CE. A superposed epoch analysis indicates that the pre-monsoon regional droughts are associated with large tropical volcanic eruptions, appearing to have a strong influence on hydroclimatic conditions in the central Himalayas. In fact, the most severe drought since 1650 CE occurred after the Tambora eruption. These results suggest that dry conditions prior to monsoon in the central Himalayas were associated with explosive tropical volcanism. Prolonged La Ni?a events also correspond with persistent pre-monsoon droughts in the central Himalayas. Our results provide evidence that large tropical volcanic eruptions most likely induced severe droughts prior to monsoon in the central Himalayas. | Eryuan Liang Binod Dawadi Neil Pederson Shilong Piao Haifeng Zhu Shalik Ram Sigdel Deliang Chen | 2019 | Science Bulletin2019，64，14： | 8 |

| 3 | Comparative study between intramedullary interlocking nailing and minimally invasive percutaneous plate osteosynthesis for distal tibia extra-articular fractures显示文摘Purpose:Treatment of distal tibia fractures poses significant challenge to orthopedic surgeon because of poor blood supply and paucity of soft tissue coverage.There is considerable controversy regarding the superior option of treatment for distal tibia fracture between the minimally invasive percutaneous plate osteosynthesis(MIPPO)technique and intramedullary interlocking(IMIL)nailing for extra-articular distal tibia fractures.The aim of our study is to compare the functional outcome between the two treatment methods.Methods:This was the prospective comparative study of 100 patients with distal third tibia fractures divided into two groups.The first group of patients were treated with MIPPO technique while the second group of patients were managed by IMIL nailing.Patients were followed up in outpatient department to assess the functional outcomes,malunion,delayed union,nonunion,superficial and deep infection between the two groups.Statistical analyses were performed using the SPSS software(version 16.0).Results:Average malunion(degrees)in the MIPPO group was 5(3—7)±1.41 vs.10.22(8—14)±2.04 in the IMIL group(p=0.001).Similarly postoperative knee pain in the IMIL group was 10%vs.2%in the MIPPO group(p=0.001).In terms of superficial infection and nonunion,the results were 8%vs.4%and 2%vs.6%for the MIPPO and IMIL group,respectively(p=0.001).Conclusion:Both procedures have shown the reliable method of fixation for distal extra-articular tibia fractures preserving the soft tissue,bony vascularity and fracture hematoma that provide a favourable biological environment for fracture healing.Considering the results of the study,we have slightly more preference for the MIPPO technique. | Kapil Mani KC Bandhu Ram Pangeni Suman Babu Marahatta Arun Sigdel Amuda KC | 2022 | Chinese Journal of Traumatology2022，25，2： | 3 |
| 4 | 喜马拉雅山区高山冰缘植物并不能从变暖中受益显示文摘普遍认为变暖有利于高山植被生态系统,并已经导致冰缘植物向高海拔的扩张.珠峰山谷金字塔气象站(海拔5050 m)1994~2018的气象记录显示,高海拔山区呈显著的暖干化趋势.然而,我们依然不清楚暖干化是否对冰缘植被更新和分布造成显著影响?本研究在喜马拉雅山中段3个山谷建立了8块(30 m×120 m)滇藏方枝柏(Juniperus indica)和高山柏(Juniperus squamata)灌木线样地(海拔介于4344~5074 m之间).样地调查揭示,自20世纪90年代之前所有样地种群更新呈增加的趋势,然而90年代以来更新持续下降.种群更新与春季、夏季温度之间呈现显著的负相关关系,暗示了暖干化加剧了水分胁迫,并限制了种群的更新.另外,近60年来所有灌木线位置稳定.近30年遥感数据也证实,研究区冰缘植被无变绿趋势,甚至出现2%-6%的植被生长减弱现象.因此,进一步研究应该探讨冰缘植被生长减弱对喜马拉雅山区水循环和生物多样性的影响. | Shalik Ram Sigdel Jayram Pandey 梁尔源 Sher Muhammad Flurin Babst Steven W.Leavitt 沈妙根 朱海峰 Franco Salerno 朴世龙 J.Julio Camarero Josep Penuelas | 2021 | Science Bulletin2021，66，18： | 2 |
| 5 | Growth response of Abies spectabilis to climate along an elevation gradient of the Manang valley in the central Himalayas显示文摘The Himalayas are characterized by a broad gradient of bioclimatic zones along their elevation.However,less is known how forest growth responds to climatic change along elevation.In this study,four standard treering width chronologies of Himalayan fir(Abies spectabilis)were developed,spanning 142–649 years along an elevation gradient of 3076–3900 m a.s.l.Principal component analysis classified the four chronologies into two groups;the ones at lower elevations(M1 and M2)and higher elevations(M3 and M4)show two distinct growth trends.Radial growth is limited by summer(June–August)precipitation at M3,and by precipitation during spring(March–May)and summer at M4.It is limited by spring temperatures and winter precipitation(December–February)at M1.Tree-ring width chronologies also significantly correlate with winter and spring Palmer Drought Severity Index(PDSI)at M1,and with summer PDSI at M3 and M4.Thus,Himalayan fir growth at high elevations is mainly limited by moisture stress rather than by low temperatures.Furthermore,the occurrence of missing rings coincides with dry periods,providing additional evidence for moisture limitation of Himalayan fir growth. | Samresh Rai Binod Dawadi Yafeng Wang Xiaoming Lu Huang Ru Shalik Ram Sigdel | 2020 | Journal of Forestry Research2020，31，6： | 2 |
