| 2 | Nitrite,a novel method to decrease ischemia/reperfusion injury in the rat liver显示文摘AIM:To investigate whether nitrite administered prior to ischemia/reperfusion(I/R)reduces liver injury.METHODS:Thirty-six male Sprague-Dawley rats were randomized to 3 groups,including sham operated(n=8),45-min segmental ischemia of the left liver lobe(IR,n=14)and ischemia/reperfusion(I/R)preceded by the administration of 480 nmol of nitrite(n=14).Serum transaminases were measured after 4 h of reperfusion.Liver microdialysate(MD)was sampled in 30-min intervals and analyzed for glucose,lactate,pyruvate and glycerol as well as the total nitrite and nitrate(NOx).The NOx was measured in serum.RESULTS:Aspartate aminotransferase(AST)at the end of reperfusion was higher in the IR group than in the nitrite group(40±6.8μkat/L vs 22±2.6μkat/L,P=0.022).Similarly,alanine aminotransferase(ALT)was also higher in the I/R group than in the nitrite group(34±6μkat vs 14±1.5μkat,P=0.0045).The NOx in MD was significantly higher in the nitrite group than in the I/R group(10.1±2.9μmol/L vs 3.2±0.9μmol/L,P=0.031)after the administration of nitrite.During ischemia,the levels decreased in both groups and then increased again during reperfusion.At the end of reperfusion,there was a tendency towards a higher NOx in the I/R group than in the nitrite group(11.6±0.7μmol/L vs 9.2±1.1μmol/L,P=0.067).Lactate in MD was significantly higher in the IR group than in the nitrite group(3.37±0.18 mmol/L vs 2.8±0.12 mmol/L,P=0.01)during ischemia and the first 30 min of reperfusion.During the same period,glycerol was also higher in the IRI group than in the nitrite group(464±38μmol/L vs 367±31μmol/L,P=0.049).With respect to histology,there were more signs of tissue damage in the I/R group than in the nitrite group,and29%of the animals in the I/R group exhibited necrosis compared with none in the nitrite group.Inducible nitric oxide synthase transcription increased between early ischemia(t=15)and the end of reperfusion in both groups.CONCLUSION:Nitrite administered before liver ischemia in the rat liver reduces anaerobic metabolism and cell necrosis,which could be important in the clinical setting. | Bergthor Bjrnsson Linda Bojmar Hans Olsson Tommy Sundqvist Per Sandstrm | 2015 | World Journal of Gastroenterology2015，21，6： | 8 |
| 3 | Integrative taxonomy of the Russet Bush Warbler Locustella mandelli complex reveals a new species from central China显示文摘Background: The Russet Bush Warbler Locustella(previously Bradypterus) mandelli complex occurs in mountains in the eastern Himalayas, southern China, Vietnam, the Philippines, and Indonesia. The taxonomy has been debated,with one(L. seebohmi) to four(L. seebohmi, L. mandelli, L. montis and L. timorensis) species having been recognised.Methods: We used an integrative approach, incorporating analyses of morphology, vocalizations and a molecular marker, to re-evaluate species limits in the L. mandelli complex.Results: We found that central Chinese L. mandelli differed from those from India through northern Southeast Asia to southeast China in plumage, morphometrics and song. All were easily classified by song, and(wing + culmen)/tail ratio overlapped only marginally. Both groups were reciprocally monophyletic in a mitochondrial cytochrome b(cytb) gene tree, with a mean divergence of 1.0 ± 0.2%. They were sympatric and mostly altitudinally segregated in the breeding season in southern Sichuan province. We found that the Mt Victoria(western Myanmar) population differed vocally from other L. mandelli, but no specimens are available. Taiwan Bush Warbler L. alishanensis was sister to the L. mandelli complex, with the most divergent song. Plumage, vocal and cytb evidence supported the distinctness of the south Vietnamese L. mandelli idonea. The Timor Bush Warbler L. timorensis, Javan Bush Warbler L.montis and Benguet Bush Warbler L. seebohmi differed distinctly in plumage, but among-population song variation in L. montis exceeded the differences between some populations of these taxa, and mean pairwise cytb divergences were only 0.5–0.9%. We also found that some L. montis populations differed morphologically.Conclusions: We conclude that the central Chinese population of Russet Bush Warbler represents a new species,which we describe herein, breeding at mid elevations in Sichuan, Shaanxi, Hubei, Hunan and Guizhou provinces.The taxonomic status of the other allopatric populations is less clear. However, as they differ to a degree comparable with that of the sympatric L. mandelli and the new species, we elevate L. idonea to species status, and retain L. seebohmi and L. montis as separate species, the latter with timorensis as a subspecies. Further research should focus on different populations of L. montis and the Mt Victoria population of L. mandelli. | Per Alstrom Canwei Xia Pamela C Rasmussen Urban Olsson Bo Dai Jian Zhao Paul J Leader Geoff J Carey Lu Dong Tianlong Cai Paul I Holt Hung Le Manh Gang Song Yang Liu Yanyun Zhang Fumin Lei | 2015 | Chinese Birds2015，，2： | 4 |
| 4 | 参与式管理解决冲突:遥感和GIS用作瑞典北部驯鹿业土地利用需求信息交流的工具显示文摘在解决复杂的土地管理问题时,对短缺或者有争执的资源进行地理评估有助于不同利益相关者之间沟通认识和增进理解。本文中,我们说明如何使用遥感和GIS收集和汇总瑞典北部驯鹿放牧者和其他土地使用者(林业、采矿业、旅游业等等)的土地使用活动及使用模式的信息。该项目主要基于最终的土地使用者,即驯鹿放牧者们所做的工作,体现了面向土地使用者的新的努力。发展驯鹿业的土地利用规划的基础有以下几个方面:收集并数字化传统的驯鹿栖息地生态学和景观信息;将这些信息与来自野外调查及基于人造卫星观测的植被分类结果整合;绘制其他土地使用者的活动情况图。最终的土地利用规划提供的信息有利于驯鹿放牧者与其他利益相关者之间的磋商,并有助于驯鹿管理实施。该项目可作为一种大众参与和计划编制的模式,从而使本土信息和先进的遥感技术融入一个交互式的过程中。 | Per Sandstrm Tina Granqvist Pahlén Lars Edenius Hans Tφmmervik Olle Hagner Leif Hemberg Hkan Olsson Karin Baer Thomas Stenlund Lars Gran Brandt Mikael Egberth 周立志 程利群 | 2003 | AMBIO-人类环境杂志2003，32，8： | 4 |
| 5 | 大堡礁和大峡谷世界遗产区的适应性管理显示文摘关于人类和环境相互关系的传统观念正在迅速改变。那种认为人类与自然是相互隔离的,自然资源是取之不尽用之不竭的,而且认为世界是稳定的、可以预测的并且是平衡的旧观点已经过时了。在动态的社会-生态景观中强调学习和灵活性管理为基础的适应性方法的新的理念框架已经迅速初现端倪。我们以两个典型的世界遗产地区(大堡礁和大峡谷)为案例来研究如何在自然资源管理中通过改善科学和社会两个方面的结合来指导多尺度管理系统的变革从而应对和处理人类越来越占据主导的世界中出现的不确定性、风险和变化。 | Terence P.Hughes Lance H.Gunderson Carl Folke Andrew H.Baird David Bellwood Fikret Berkes Beatrice Crona Ariella Helfgott Heather Leslie Jon Norberg Magnus Nystrm Per Olsson Henrik sterblom Marten Scheffer Heidi Schuttenberg Robert S.Steneck Maria Teng Max Troell Brian Walker James Wilson Boris Worm 丁莉 | 2007 | AMBIO-人类环境杂志2007，36，B11： | 4 |
| 6 | 莺总科鸟类的系统分类进展评述(英文)显示文摘本文评述了莺总科鸟类的系统分类,并重点探讨科间、属内系统发育关系以及种级分类地位。基于已发表的 DNA 序列数据,对马岛莺科(Bernieridae)和柳莺科(Phylloscopidae)重新进行了分析。大量的分子水平的研究让我们对鸟类系统发育的认识有了很大提高。但是,由于一些主要进化分支(科)的快速分化,使得这些科之间的相互关系依然不明确。同样,分子标记和(或)鸣声及其他生活史资料在大量研究中的应用,大大提高了种级水平的分类可靠性。我们推测,随着人们运用现代的整合方法对新类群的不断研究,物种数量会不断增加。 | Per ALSTRM Urban OLSSON 雷富民 | 2013 | Chinese Birds2013，，2： | 3 |
| 7 | 水生生态系统的富营养化和污染物显示文摘富营养化和长效污染物是欧洲海洋和淡水生态系统存在的主要环境问题。由于它们趋于共同产生,所以富营养化和污染物之间就有了相互作用,因而无法根据它们各自独立的作用过程来预测它们共同导致的环境影响。为了预测防治措施(改变有机质、营养物和污染物的输入)的效果,认识改变生物可利用性和污染物的迁移转化的机制是非常重要的。环境风险取决于污染物的种类形成和它们与媒介及其物质间的联系,并以此影响暴露程度。而且,风险也将取决于物质的流动性和它们在食物链中的路径。1995年,瑞典环境保护局发起了一项为期5年的研究项目'富营养化和污染物之间的相互作用(EUCON)'。前期准备的有关背景资料罗列了大量相关的问题和假设。在这些资料的基础上,项目开始启动,主要致力于海洋环境研究,重点集中在波罗的海及湖泊的富营养化和污染物(持续性有机化合物和微量金属)的相互作用上。本文总结了该项目研究的现状、前提和重点部分,强调了研究结果的应用及其意义。 | Jens Skei Per Larsson Rutger Rosenberg Per Jonsson Mats Olsson Dag Broman 鲁春霞 | 2000 | AMBIO-人类环境杂志2000，29，4： | 2 |

| 11 | Integrative taxonomy of the Plain-backed Thrush(Zoothera mollissima)complex(Aves,Turdidae)reveals cryptic species,including a new species显示文摘Background: The Plain-backed Thrush Zoothera mollissima breeds in the Himalayas and mountains of central China. It was long considered conspecific with the Long-tailed Thrush Zoothera dixoni, until these were shown to be broadly sympatric.Methods: We revise the Z. mollissima–Z. dixoni complex by integrating morphological, acoustic, genetic(two mitochondrial and two nuclear markers), ecological and distributional datasets.Results: In earlier field observations, we noted two very different song types of 'Plain-backed' Thrush segregated by breeding habitat and elevation. Further integrative analyses congruently identify three groups: an alpine breeder in the Himalayas and Sichuan, China('Alpine Thrush'); a forest breeder in the eastern Himalayas and northwest Yunnan(at least), China('Himalayan Forest Thrush'); and a forest breeder in central Sichuan('Sichuan Forest Thrush'). Alpine and Himalayan Forest Thrushes are broadly sympatric, but segregated by habitat and altitude, and the same is probably true also for Alpine and Sichuan Forest Thrushes. These three groups differ markedly in morphology and songs. In addition, DNA sequence data from three non-breeding specimens from Yunnan indicate that yet another lineage exists('Yunnan Thrush'). However, we find no consistent morphological differences from Alpine Thrush, and its breeding range is unknown. Molecular phylogenetic analyses suggest that all four groups diverged at least a few million years ago, and identify Alpine Thrush and the putative 'Yunnan Thrush' as sisters, and the two forest taxa as sisters. Cytochrome b divergences among the four Z. mollissima sensu lato(s.l.) clades are similar to those between any of them and Z. dixoni, and exceed that between the two congeneric outgroup species. We lectotypify the name Oreocincla rostrata Hodgson, 1845 with the Z. mollissima sensu stricto(s.s.) specimen long considered its type. No available name unambiguously pertains to the Himalayan Forest Thrush.Conclusions: The Plain-backed Thrush Z. mollissima s.l. comprises at least three species: Alpine Thrush Z. mollissima s.s., with a widespread alpine breeding distribution; Sichuan Forest Thrush Z. griseiceps, breeding in central Sichuan forests; and Himalayan Forest Thrush, breeding in the eastern Himalayas and northwest Yunnan(at least), which is described herein as a new species. 'Yunnan Thrush' requires further study. | Per Alstrom Pamela C.Rasmussen Chao Zhao Jingzi Xu Shashank Dalvi Tianlong Cai Yuyan Guan Ruiying Zhang Mikhail V.Kalyakin Fumin Lei Urban Olsson | 2016 | Chinese Birds2016，，1： | 2 |

| 16 | Taxonomy of the White-browed Shortwing(Brachypteryx montana)complex on mainland Asia and Taiwan:an integrative approach supports recognition of three instead of one species显示文摘Background: The White-browed Shortwing(Brachypteryx montana) is widespread from the central Himalayas to the southeast Chinese mainland and the island of Taiwan, the Philippines and Indonesia. Multiple subspecies are recognised, and several of these have recently been suggested to be treated as separate species based on differences in morphology and songs.Methods: We here analyse plumage, morphometrics, songs, two mitochondrial and two nuclear markers, and geographical distributions of the two mainland Asian taxa B. m. cruralis and B. m. sinensis and the Taiwan Residents B. m. goodfellowi.Results: We conclude that these differ congruently in morphology, songs and DNA. Male B. m. goodfellowi is the most divergent in plumage(sexually monomorphic, unlike the two others; male similar to female), and B. m. cruralis and B. m. sinensis differ in male plumage maturation. The song of B. m. cruralis is strongly divergent from the others, whereas the songs of B. m. sinensis and B. m. goodfellowi are more similar to each other. Brachypteryx m. sinensis and B. m. goodfellowi are sisters, with an estimated divergence time 4.1 million years ago(mya; 95% highest posterior distribution [HPD] 2.8–5.5 mya), and B. m. cruralis separated from these two 5.8 mya(95% HPD 4.1–7.5 mya). We also report notable range extensions of B. m. sinensis as well as sympatry between this taxon and B. m. cruralis in Sichuan Province, China. Brachypteryx m. montana from Java is found to be more closely related to Lesser Shortwing(B. leucophris) and Rusty-bellied Shortwing(B. hyperythra) than to the mainland Asian and Taiwan Residents taxa.Conclusion: Our data support a recent proposal to treat the three mainland Asian and Taiwan Residents taxa as three species, separate from B. montana sensu stricto: B. cruralis(central Himalayas to south central China and south Vietnam), B. sinensis(north central to southeastern part of China's Mainland) and B. goodfellowi(Taiwan Island). | Per Alstrom Pamela C.Rasmussen Canwei Xia Magnus Gelang Yang Liu Guoling Chen Min Zhao Yan Hao Chao Zhao Jian Zhao Chengte Yao James A.Eaton Robert Hutchinson Fumin Lei Urban Olsson | 2018 | Avian Research2018，9，4： | 1 |
