Background:field studies from 2011 onwards have demonstrated the presence of a breeding population of Yellow Wagtails(Motacilla flava)in the Xinjiang Uygur Autonomous Region,China that is phenotypically distinct from known subspecies occurring in *** we describe the plumages and vocalisations of this population and discuss its taxonomic ***:The analysis of plumage is based on field studies and photos available *** of vocalisations are compared with recordings from other Yellow Wagtail populations,and differences are analysed based on *** DNA from one individual is compared to other Yellow Wagtail ***:Unlike *** subspecies breeding in or near Xinjiang,males in the studied population show a blue-grey head without prominent white supercilium,being most similar to the widely disjunct *** differ from the similarly widely allopatric ***,which might occur as a migrant or vagrant in Xinjiang,by on average cleaner yellow breast and more extensive white on the throat,and from the widely disjunct *** and ***,which might also occur on migration in that area,by softer contact calls and slower pace of *** are similar to female *** in *** mitochondrial ND2 tree shows the single sample from Xinjiang to be nested in the clade of western Yellow Wagtail ***:We discuss whether the Xinjiang breeding population could represent an intergrade between subspecies breeding nearby,or whether it is better regarded as a separate as yet unrecognized *** argue that the localization of its apparent range in relation to other subspecies along with fairly consistent male and female plumages suggest that it is more likely to represent an undescribed taxon,but conclude that more research is needed to firmly establish its status.

Background: Postzygotic isolation in the form of reduced viability and/or fertility of hybrids may help maintain species boundaries in the face of interspecific gene flow. Past hybridization events between house sparrows(Passer domesticus) and Spanish sparrows(P. hispaniolensis) have given rise to a homoploid hybrid species, the Italian sparrow(P. italiae). Although genetic incompatibilities are known to isolate these three species, the biological consequences of these incompatibilities are still unknown in early generation ***: We investigated whether f1 hybrids between house and Spanish sparrows experience reduced viability or fertility. More specifically, we generated hybrids through controlled crosses in aviaries, and compared ovaries of female hybrids with female of pure?species ***: We found that overall, hybrid ovaries were underdeveloped and that half of all female hybrids exhibited symptoms of ovarian hypofunction(ovarian atrophy and complete absence of developed follicles).Conclusions: fertility in hybrids is a common consequence or post?zygotic barriers between species. We discuss these results in light of previous findings on genetic incompatibilities between the parent species and the potential role of incompatibilities in hybrid speciation, a rare evolutionary process in birds.

目前东亚地区基于代用资料的大尺度温度重建几乎都关注夏季或年平均温度的变化,而对冬季温度的研究比较少.鉴于此,本研究利用260条温度敏感的树轮记录,重建了时间分辨率为年、空间分辨率为5°×5°、时间长度为公元1300~2000年的东亚冬季(12~2月)平均温度.结果表明,自14世纪以来冬温呈现出显著的长期升温趋势,但在公元1625(±24)年出现了年温度循环(冬温-夏温)的长期衰减.年际尺度上东亚冬温的振幅大约是夏温的4.7倍,上升速率大约是夏温的6倍.气候模式模拟的结果与重建的结果一致,均表现出东亚冬温的幅度和速率大于夏温的.研究表明,冬温的这种上升趋势主要受到北半球中纬度地区(30°N~50°N)的冬季太阳辐射和人类活动的影响.另外,在年际尺度上,本研究检测到东亚冬温主要受到火山喷发、太阳辐射和人类活动的共同影响.

公元536~540年间的大规模火山喷发使得晚古小冰期成为过去两千年最为寒冷的时期.然而,受限于现有气候代用资料的时间分辨率和空间覆盖度,晚古小冰期的开始时间和空间范围仍存有争议.本文分析了全球23个森林样点、20个树种的106个树轮样本资料,从细胞尺度揭示了公元530~550年间北半球发生的短暂夏季冷却现象.经过交叉定年和染色处理后,在北半球的树轮样品中共识别出89个蓝轮(缺失细胞壁木质化过程)、9个霜轮(细胞分裂受阻)和93个浅轮(细胞壁增厚减弱).研究结果表明,公元536年7月中旬至8月初期间整个北美和欧亚大陆均发生了最剧烈的温度下降,而更多的区域性“冷夏”出现于公元532年、540~543年和548年.然而,本研究在南半球的树轮资料中并未发现异常的解剖结构,其原因可能与南半球的海洋热惯性减缓了火山降温效应有关,也或与南半球其时正值非生长季有关.相较于传统的树轮年代学方法,本研究的木材解剖学的方法能为地球系统模式提供更为精细的参考标准,有望服务于气候与人类历史交叉学科研究,同时对“全球气候平均”概念的使用提出质疑.
