神经毒素深处

属的一些物种 Pseudo-nitzschia 令人讨厌的小硅藻。它们产生多象酸,一种神经毒素通常归咎于各种海洋脊椎动物死亡。阿尔弗雷德希科克斯’s 1963 film “The Birds”将鸟类攻击陷入困境的鸟类攻击符号。已经过滤伪尼科斯的人类消费贝类导致艾默地贝类中毒。一顿美味的牡蛎洛克菲勒可以导致短期内存损失。它出现,我们作为人类应该责备,那些由这些Wee-BeaSties主导的藻类绽放在频率和持续时间内都在增加。

新的研究 自然地球科学 发现Domicoider可以使其深入了解。沉积物陷阱设定在南加州南部的海面下方500米和800米。“沉没的粒子包含在内 five times 美国联邦大甲酸的联邦极限。”峰恰好仅落后几天表面浓度的峰,这意味着大使酸的运输是立即的。以前的工作发现,对于欧陆式架子和整个水柱的生物来说,普遍存在。本研究表明,深海生物中的民族酸浓度也可能相当大。

将其添加到另一种方式,人为扰动达到深处。

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.

  1. 哇,那’令人恐惧。想想所有可怜的过滤喂食器!我们应该在我们的研究生物中进行生物测定。我想知道你是否需要新鲜或冷冻材料。
