| 1 | Tree diversity and nectar composition affect arthropod visitors on extrafloral nectaries in a diversity experiment显示文摘Aims Plants with extrafloral nectaries(EFNs)are common in tropical and subtropical habitats and,despite many other arthropods also forage for EFN,most studies solely focused on the defense mutualisms between EFN plants and ants.This study aims at a quantitative assessment of the entire arthropod community that visits EFN trees to compare visitor communities between different tree species to disentangle the mechanisms that may drive EFN visitor community composition.We also test for tree diversity effects on EFN visitors,as it is unknown if local tree species richness relates to the abundance and species richness of arthropods foraging for EFN.Methods We sampled EFN-visiting arthropods in the experimental tree species richness gradient of the BEF-China Experiment,the currently largest forest diversity experiment in the world,and tested if tree species richness affects EFN visitors and if visitor community composition differs between EFN tree species.In a second step,we analyzed the EFN of Ailanthus altissima and Triadica cochinchinensis,the two EFN tree species with highest visitor abundance,for sugars and amino acids(AA)to test if tree species-specific differences in nectar chemistry translate to differing visitor communities.Lastly,we conducted a choice experiment using different artificial nectar solutions to test if nectar quality affects foraging decisions of ants,the most frequent EFN visitors in our study sites.Important Findings EFN trees in young successional forests in subtropical South-East China are visited by a diverse assemblage of arthropods including ants,beetles,flies,and spiders.Albeit ants accounted for about 75%of all individuals,non-ant visitors were by far more species rich.Visitor abundance and species richness declined with increasing tree species richness,suggesting a resource dilution effect,because plots with more tree species had proportionally less EFN tree individuals and thus lower nectar availability.Ailanthus altissima and T.cochinchinensis were visited by different arthropods and their nectar had species-specific AA composition and sugar concentration,indicating that differences in visitors may,at least partly,be explained by differences in nectar chemistry.These findings are supported by the choice experiment,in which artificial nectars containing sugar solutions supplemented with essential AAs attracted more ants than pure sugar solutions or sugar solutions supplemented with non-essential AAs.Our results improve the understanding of the complex ecology of EFN trees,a plant life form that might be crucial for understanding how tree diversity influences patterns of tree growth in young successional tropical and subtropical forests. | Michael Staab Joel Methorst Jan Peters Nico Blüthgen Alexandra-Maria Klein | 2017 | Journal of Plant Ecology2017，10，1： | 6 |
| 2 | 儿科患者心理社会风险评估量表的汉化及信效度检验显示文摘目的汉化儿科患者心理社会风险评估(Psychosocial Risk Assessment in Pediatrics,PRAP)量表,并检验其信效度。方法获得原作者授权后进行翻译、文化调适,形成中文版PRAP量表。采用便利抽样法,选取2021年3月—5月于上海市某三级甲等儿童专科医院住院的167例患者进行心理社会风险评估,检验量表的信效度。结果中文版PRAP量表包括性情、诊疗环境中的焦虑和应对、诊疗经历、发育或发展程度对应对能力的影响、特殊需求、沟通、侵入性操作经历、父母或照顾者的压力8个条目,量表的Cronbach’sα系数为0.711,折半信度为0.626。5名调查员评定结果的肯德尔和谐系数为0.963,χ^(2)值为43.325,差异具有统计学意义(P<0.001)。各条目的内容效度指数为0.90~1.00,量表的平均内容效度指数为0.95。探索性因子分析提取3个公因子,累计方差贡献率为62.686%。结论中文版PRAP量表具有较好的信效度,可作为评估儿科患者就医相关心理社会风险的评估工具。 | 张燕红 张晓波 顾莺 康琼芳 傅丽丽 董颖 朱大倩 傅唯佳 冯瑞 Staab Jennifer | 2022 | 中华护理杂志2022，57，10： | 4 |
