简介：摘要：不完全的postcranial鸟的骨骼从西方的内部蒙古的Otog旗帜的更低的白垩纪Jingchuan形成被描述并且指了Cathayornis的新种，C。chabuensissp。nov。这是从外面的辽宁省的Cathayornis的第一份报告。新发现显示Cathayornis与Otogornisgenghisi共存了，并且更多详细说明了在Otogornis代表的这二enantiornithine类表演之间的比较一个更原始的类比Cathayornis。我们的分析进一步显示Cathayornis是一只树木的鸟。从这个区域的Cathayornis的发现也证实鸟的忍受石块的Jingchuan形成比得上在西方的辽宁的上面的Jehol组的Jiufotang形成，并且应该被指中间迟了的早白垩纪。

简介：大多数phaeophytes(棕色的水藻)和rhodophytes(红水藻)专门在海洋的产地居住并且在海洋的生态学和生物多样性起重要作用。许多这些棕色、红的水藻也是为象由于他们的唯一的新陈代谢和代谢物的食物，药和材料那样的工业的重要资源。然而，因为差的分子的底，包围他们的起源，早多样化，分类，和特殊新陈代谢的许多基本问题在棕色、红的海藻的学习仍然保持未解决。作为1000植物工程的部分，从瓷器海岸的19Phaeophyceae种类和21Rhodophyta种类的海洋的macroalgaltranscriptomes被定序，盖住2数，3个班，11份订单，和19个家庭的一个总数。2Gb的一般水准每样品和一个总数，RNA-seq未加工的数据的87.3Gb被产生。为每件棕色的海藻的样品的约15000～25000unigenes和为每件红海藻的样品的5000～10000unigenes被注解并且分析。注解结果在在红水藻和棕色的水藻之间的基因表示和染色体特征显示出明显的差别；这些差别能甚至在多细胞、单细胞的红水藻之间被看见。结果阐明关于在phaeophytes和rhodophytes以内的种系发生的分类的一些基本问题，并且也揭示许多新奇新陈代谢的小径。这些小径包括海藻的CO2固定和特别糖类在棕色、红的水藻的新陈代谢，和相关基因/基因家庭特征和进化。这些调查结果在已知的海藻的基因信息上造并且显著地改进我们这些海洋的水藻的海藻的生物学，生物多样性，进化，和潜在的利用的理解。
