1西双版纳黄瓜农家品种及其传统知识显示文摘西双版纳黄瓜(Cucumis sativus var. xishuangbannanesis)是黄瓜的一个变种。云南省西双版纳及周边地区的少数民族长期以来栽培、管理和利用这种黄瓜,使它成为当地重要的作物农家品种,对其开展民族植物学研究,了解其传统知识十分必要。我们于2017–2018年在西双版纳傣族自治州调查了西双版纳黄瓜农家品种及其相关的传统知识。结果表明,与现代品种相比,西双版纳黄瓜农家品种具有香味浓郁、耐贮藏等特异性;西双版纳的傣族、基诺族、彝族、瑶族等少数民族拥有丰富的关于西双版纳黄瓜农家品种的传统知识。西双版纳黄瓜种质资源在大部分村寨已经消失或濒临消失,与之相关的传统知识也随之消亡,目前仅在海拔较高、交通欠发达的边远山区还栽培和保留了少量的农家品种。建议开展西双版纳黄瓜农家品种的原生境保护,既保护其种质资源,也保护相关的传统知识。杨云卉 白可喻 Devra Jarvis 龙春林 2019生物多样性2019,27,7:6
2圈养大熊猫性情、饲养管理和社群-性行为的关系(英文)显示文摘以往研究表明,许多成年雄性大熊猫在圈养状态下不能表达正常的社群性行为。我们设计了一个实验来研究大熊猫正常社群性行为与性情特征、展示、以及饲养管理的关系。通过调查获得大熊猫展示和饲养管理的数据,询问饲养员得知2001年繁殖季节中大熊猫的社群性行为发生频次,然后评估社群性行为能力。研究对象是分布在中国4个繁育中心的37头(12头雄性和25头雌性)成体大熊猫。通过提供新物品和气味来评估大熊猫情绪反应状况。情绪反应分为3类:畏惧、访问和访问玩耍。在有饲养员陪同玩耍的一组里,雌、雄大熊猫的'访问玩耍'的分值都较高。'畏惧'类的雌性大熊猫气味标记行为少,表达的性行为也少,并且更多地攻击接近它们的雄性,或者不理睬雄性。在繁殖季节前就接近雄性大熊猫围栏的雌性,表现出更多的气味标记行为和性行为。这些雌性的'访问玩耍'分值也高。'访问'分值高的雄性大熊猫,接近雌性的行为更多。那些与饲养员接触时间少的雄性大熊猫倾向于攻击雌性,与那些攻击性小的雄性相比,这些雄性倾向于能够接受丰富性低的环境。这些结果表明,应该采取措施减少大熊猫的畏惧,在大熊猫和饲养员之间建立积极的关系,在繁殖季节之前,增加雌性和雄性之间的熟悉程度。David POWELL 林虹 Kathy CARLSTEAD Devra KLEIMAN 张和民 张贵权 张志和 余建秋 张金国 卢雁平 Timothy S.K.NG Jason C.L.TANG Rebecca SNYDER 2008动物学报2008,54,1:3

5铜纳米颗粒的制备、尺寸控制及催化应用(英文)显示文摘以维生素C为还原剂和覆盖剂,在水溶液中制备铜纳米颗粒,并研究其催化性能。研究不同维生素C浓度对铜纳米颗粒尺寸的影响。采用紫外-可见光分光光度计、扫描电子显微镜(SEM)、透射电子显微镜及傅里叶变换红外光谱计(FTIR)对所制备的铜纳米颗粒进行表征。结果表明,随着维生素C浓度的增加,铜纳米颗粒的尺寸减小。维生素C在防止纳米颗粒氧化和团聚过程中起重要作用,可帮助纳米颗粒在应用过程中保持较高的稳定性。所制备的铜纳米颗粒在PMS氧化丝氨酸过程中表现出优良的催化活性。铜纳米颗粒的催化活性随颗粒尺寸的减小而提高。铜纳米颗粒有望用于催化和环境修复领域并发挥重要作用。Shikha JAIN Ankita JAIN Pranav KACHHAWAH Vijay DEVRA 2015Transactions of Nonferrous Metals Society of China2015,25,12:1

17Comparison of fatty acid composition,phytochemical profile and antioxidant activity in four flax(Linum usitatissimum L.)varieties显示文摘The present study evaluates variations among flaxseed varities in terms of fatty acid composition,phytochemical profile,and antioxidant activity determined by oxygen radical absorbance capacity(ORAC),2,2-Diphenyl-1-picrylhydrazyl(DPPH)and ferrous ion reducing antioxidant power(FRAP)assays.Significant variations in fatty acid composition,phenolic acids and lignan were observed in flaxseed varieties from different countries.Among them,unsaturated fatty acids accounted over 4/5 of total fatty acid content.The highest ratio of linolenic acid of total fatty acid was observed in USPEA,whereas the lowest one was found in Yexiao.USPEA showed the highest content of total phenolics,as well as flaxseed lignan.In general,total phenolics appeared to be the main contributors of antioxidant capacity of flaxseed,which presented significant positive correlation.Our study revealed that both cultivar and origin of seed significantly affected fatty acid composition,phenolic acids,lignans and subsequent antioxidant activity of flaxseed.These results provided new aspects of breeding resources of flaxseed cultivars by presenting their quality specification and possible commercial value.Caisheng Qiu Hong Wang Yuan Guo Songhua Long Yufu Wang Arshad Mehmood Abbasi Xinbo Guo Devra I.Jarvis 2020Oil Crop Science2020,5,3:1
