借助互联网模因的珊瑚居住藤壶叙事

屏幕截图2014-08-17在下午2.44.25不是珊瑚上的一切都是珊瑚。嵌入硬珊瑚的表面是近100种专门的雄疮 - Pyrgomatidae。 Malay和FrançoisMichonneau的新工作表明,我们对不同的疟原虫有关的理解是有关的......丑陋错误。该团队测序超过350种不同的基因。使用一些非常喜欢的数学方式方法,包括我的最爱Mafft之一,该集团为珊瑚居住的藤壶制作了一种新的进化遗传相关性。然后真正的乐趣开始了。屏幕截图2014-08-17在下午2.46.47

首先,二重奏发现一个属, Wanella.,通常被认为是一种杀虫剂,应该把它包装起来,因为它与群体的其余部分没有密切相关。其次,Pyrgomatidae通常分为三个不同的基团。实际上,团队确实检索了三个不同的群体。但他们是完全不同的群体。当他们说明有“需要修改杀虫病的分类时,作者是谦虚的。

30246653024691只有一个特质似乎在两个相关群体中被保守。幼虫沉淀在宿主珊瑚的表面上,一旦发生这种生长就会迅速。成年钻石必须继续垂直成长,否则珊瑚将过度重长它。横周节周围的珊瑚生长也可受到化学试剂的释放的限制。珊瑚矿石也通过龟头“牙齿”刮掉迫使甲壳类动物的珊瑚边缘来防止。这种“牙齿”似乎只在帕尔加莫唑类中进化。

Craig McClain is the Executive Director of the Lousiana University Marine Consortium. He has conducted deep-sea research for 20 years and published over 50 papers in the area. He has participated in and led dozens of oceanographic expeditions taken him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses on how energy drives the biology of marine invertebrates from individuals to ecosystems, specifically, seeking to uncover how organisms are adapted to different levels of carbon availability, i.e. food, and how this determines the kinds and number of species in different parts of the oceans. Additionally, Craig is obsessed with the size of things. Sometimes this translated into actually scientific research. Craig’s research has been featured on National Public Radio, Discovery Channel, Fox News, National Geographic and ABC News. In addition to his scientific research, Craig also advocates the need for scientists to connect with the public and is the founder and chief editor of the acclaimed Deep-Sea News (http://jiaxiangsuji.com/), a popular ocean-themed blog that has won numerous awards. His writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web.
