1Integrative 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 2015Chinese Birds2015,,2:4

4SEDIMENT YIELD AND HYDROLOGY INNORTHWESTERN RANGELANDS显示文摘Much of the rangeland of northwestern North America occupies highly variable, high-relief terrain withsteep slopes, contrasting aspects, strong elevation gradients and diverse local climates. Rangeland erosionand sediment production are major concerns in northwestern natural resource management. Seasonalvariability in precipitation, streamflow and energy available for sediment rnobilization and transport ispronounced in northwestern rangeland catchments; thus, runoff and sediment yield exhibit high spatialand temporal variability. The sediment regime of such watersheds cannot be characterized by simpleindices or short-term local measurements. A long-term experimental rangeland watershed demonstratesthe need for sustained measurement programs over a range of catchment scale and topographic position, todetermine actual patterns and rates of runoff and sediment yield. More research is needed to identify andquantify the pathways of sediment from initial detachment to temporary storage and subsequentremobilization and transport through the stream system. The role of extreme hydrologic events inaccelerated landscape erosion, remobilization of stored sediment, and interaction with dynamic channel-forming processes in rangeland streams remains inadequately defined. It is necessary to better determinelandscapes and channels susceptible to treatment to reduce stream sedimentation, and to populate andparameterize simulation models for rangeland catchmenhstream systems. Such information is requiredto address emerging issues of riparian zone and water quality management in northwestern rangelands.Charles W.

6胆固醇酯转移蛋白基因的蛋白质截断型变异体与冠状动脉性心脏病风险的关系显示文摘随机对照试验结果表明,抑制胆固醇酯转运蛋白(cholesteryl ester transfer protein,CETP)的疗法并不能降低冠状动脉性心脏病(coronary heart disease,CHD)的发生风险。研究失败的可能原因包括靶目标无效、靶目标外小分子的不良反应和随机对照设计因素影响等。在编码药物靶点的基因中具有天然存在的遗传变异,以此为基础,人类研究可以深入了解针对基因产物的治疗的潜在功效和安全性。Nomura A Won HH Khera AV Takeuchi F Ito K McCarthy S Emdin CA Klarin D Natarajan P Zekavat SM Gupta N Peloso GM Borecki IB Teslovich TM Asselta R Duga S Merlini PA Correa A Kessler T Wilson JG Bown MJ Hall AS Braund PS Carey DJ Murray MF Kirchner HL Leader JB Lavage DR Manus JN Hartze DN Samani NJ Schunkert H Marrugat J Elosua R McPherson R Farrall M Watkins H Juang JJ Hsiung CA Lin SY Wang JS Tada H Kawashiri MA Inazu A Yamagishi M Katsuya T Nakashima E Nakatochi M Yamamoto K Yokota M Momozawa Y Rotter JI Lander ES Rader DJ Danesh J Ardissino D Gabriel S Willer CJ Abecasis GR Saleheen D Kubo M Kato N Ida Chen YD Dewey FE Kathiresan S 刘莉 叶鹏 2017中华高血压杂志2017,25,9:2
