1Increasing phylogenetic support for explosively radiating taxa: The promise of high-throughput sequencing for Oxytropis (Fabaceae)显示文摘高山的生物区系的起源和进化充分还没被理解,特别地在广阔的亚洲山区域。在这些区域,另外,大多数研究专注于在从夏天季风得益于相对慷慨的降雨的区域发生的 taxa。在这研究,我们在整个他们的分发范围收集了很多 Oxytropis 种类,并且调查了这个多样的荚类的分类和进化,它也发生在对干旱敏感的多山的区域。用原子(它的) 并且质体(trnL-F ) 标记,我们重建了在 Oxytropis 以内的种系发生的关系,进行最大的吝啬,象 fasttree 一样,最大的可能性的,贝叶斯,并且野兽分析。我们也使用了抛锚的混合丰富(AHE ) 测试这个方法的力量在 Oxytropis 种类的一个小子集之中解决关系。为 AHE,我们取样了八种并且获得了 527 低拷贝并且 orthologous 原子 loci。我们证明在亚洲山爆发地放射了的这个类的分类将基于常规分子的方法仍然保持不顺从。因为分辨率的严重缺乏,任何一个也都不能为 Oxytropis 的可得到的分类处理被证实或反驳在它的 and trnL-F 之上基于。不过,我们证实几种的地位,并且为一些组种类识别词法或基因的个性。AHE 途径产出一棵高度支持的种系发生的树,建议那增加的 taxon 采样结合了方法答应在 Oxytropis 的分类和进化的学习的进展的 AHE,因此提供进一步分析的机会,例如多样化率和 biogeographical 分析。Robabeh Shahi Shavvon Shahrokh Kazempour Osaloo Ali Asghar Maassoumii Farideh Moharrek Seher Karaman Erkul Alan R.

2Spatio-temporal evolution of Allium L. in the Qinghaie-Tibet-Plateau region: Immigration and in situ radiation显示文摘A plethora of studies investigating the origin and evolution of diverse mountain taxa has assumed a causal link between geological processes(orogenesis) and a biological response(diversification). Yet, a substantial delay(up to 30 Myr) between the start of orogenesis and diversification is often observed.Evolutionary biologists should therefore identify alternative drivers of diversification and maintenance of biodiversity in mountain systems. Using phylogenetic, biogeographic, and diversification rate analyses,we could identify two independent processes that most likely explain the diversity of the widespread genus Allium in the Qinghaie-Tibet Plateau(QTP) region:(1) While the QTP-related taxa of the subgenus Melanocrommyum diversified in situ,(2) QTP-related taxa of other subgenera migrated into the QTP from multiple source areas. Furthermore, shifts in diversification rates within Allium could not be attributed spatially and temporally to the uplift history of the QTP region. Instead, global cooling and climate oscillations in the Quaternary were major contributors to increased speciation rates in three clades of Allium. Our study therefore adds to the growing evidence supporting the 'mountain-geo-biodiversity hypothesis', which highlights the role of climate oscillations for the diversification of mountain organisms.Frank Hauenschild Adrien Favre Jan Schnitzler Ingo Michalak Martin Freiberg Alexandra N.
