1尼泊尔中部山区麦拉姆齐流域农户生计资本与生计策略关系研究显示文摘生计资本与生计策略关系的研究是理解和发展农村可持续生计最重要的途径。本文以尼泊尔中部山区麦拉姆齐流域为例,采用PRA法进行实地调研,定量分析了该流域农户的生计资本状况,生计资本对生计策略的影响及不同生计策略对生计资本因子的敏感性特征。研究表明:(1)农户生计资本指数低,各类资本差异明显,且资本的转化能力弱。物质资本得分最高,其次为人力资本、社会资本、金融资本,自然资本最低。(2)以非农为主型生计策略农户的资本总指数最高,生计策略也相对最优;非农型资本总指数次之,但生计风险相对较高;农为主型资本总指数低于前二者,但生计脆弱性相对较低;纯农型资本总指数最低,生计策略组合单一,生计风险相对最高。(3)生计资本及其组合差异是影响农户生计策略选择的重要原因,改善生计资本的配置能够推动农户生计策略的调整和优化。不同生计策略对资本因子的敏感性亦有所差异,提高人力资本和金融资本的投入,对于尼泊尔山区农户积极参与和发展非农生计活动,合理调整和优化生计策略,减小生计风险具有重要意义。苏艺 邓伟 张继飞 Hriday Lal Koirala Paudel Khatiwada Shanta 2016山地学报2016,34,5:7
2A Complete Embryonic Developmental Table of Microhyla fissipes(Amphibia,Anura,Microhylidae)显示文摘Access to embryonic developmental stages is essential basic work for understanding how organisms develop. In this study, seven egg clutches(range 209–564 eggs) of ornamented pygmy frog Microhyla fissipes(Amphibia, Anura, Microhylidae) were obtained from seven breeding pairs in laboratory. One egg clutch of them was observed for the embryonic development, and the staging table of normal development was constructed based on morphological and physiological characteristics. Forty-five developmental stages were defined for M. fissipes, and two major developmental periods were designated: 1) early embryonic development period(stages 1–28), from fertilization to operculum completion stage, lasted for 82.6 hours at water temperature(WT) 23–25℃; 2) larval development period(stages 29–45), from operculum completion to tail complete absorption stage, took 38 days at WT 22–26.5℃, showing that the embryos of this species develop rapidly. In addition, the tadpoles were transparent, which is similar to those in field. These characteristics suggest that M. fissipes would be a good model to study developmental biology, adaptive mechanisms from aquatic to terrestrial phases, environmental toxicology, and human disease.Shouhong WANG Lanying ZHAO Lusha LIU Dengwei YANG Janak Raj KHATIWADA Bin WANG Jianping JIANG 2017Asian Herpetological Research2017,18,2:5
3A New Species of the Genus Tylototriton(Amphibia: Urodela: Salamandridae) from Eastern Himalaya显示文摘A new species of the genus Tylototriton is described from eastern Himalaya based on molecular and morphological comparisons. The new species is diagnosable from the closely-related species by having light brown colouration in dorsal region in life, flat and blunt snout, greatly separated dorsolateral bony ridges on head and straightthick tailfin. In addition to head morphology, the new species is also morphologically distinguishable from its closelyrelated species Tylototriton shanorum by having 16 dorsal warts and average smaller Snout Vent Length(SVL).Janak Raj KHATIWADA Bin WANG Subarna GHIMIRE Karthikeyan VASUDEVAN Shanta PAUDEL Jianping JIANG 2015Asian Herpetological Research2015,6,4:3

14An Integrative Taxonomy of Amphibians of Nepal:An Updated Status and Distribution显示文摘Amphibians are declining worldwide.At the same time,each year many species of amphibians are described,indicating that biological diversity on Earth remains poorly understood.This is especially true for mountainous regions,such as the Himalayas,which are also regarded as a biodiversity hotspot.However,it is most likely that the current diversity of amphibians in Nepal is highly underestimated.Amphibian inventories by the past researchers primarily used phenotypic characters as the basis for species identification.However,the application of molecular systematics methods to taxonomic studies has successfully uncovered the taxonomic status of several cryptic taxa.This study used both molecular(16 S rDNA sequences)and morphological comparisons and estimated the diversity of amphibians from Nepal.This study reports the occurrence of 38 species of amphibians based on both molecular and morphological comparisons.Among them,three species were recorded for the first time in Nepal.This study also invalids the taxonomic status of Sphaerotheca paschima.This study highlights the importa nce of integrative taxonomic approaches that help to resolve the current taxonomic ambiguities of Nepalese amphibians.Janak Raj KHATIWADA Bin WANG Tian ZHAO Feng XIE Jianping JIANG 2021Asian Herpetological Research2021,12,1:1
