UTS Science in Focus: Marine Microbes: The Ocean's Lifeblood?
How do these tiny microbes contribute to ocean function and how will they respond to climate change?
Over 70% of Earth is covered by ocean, but when we think of life in the ocean, we often think of fish, sharks, and whales - life that is visible to the naked eye. You'll be amazed to learn that most life in the ocean is microbial -- the tiny, invisible organisms!
Over 90% of ocean biomass is made up of marine microbes. So what are they? They include the ocean's bacteria, viruses and algae. They are also the most diverse and abundant organisms on earth. They are essential in the function of the ocean because they are the foundation of our marine food-web and are critically important in preserving ecosystem functions and supporting fisheries production. These tiny marine microbes even influence our climate by driving the earth's major chemical cycles.
Dr Martina Doblin and Dr Justin Seymour examine the role and challenges in studying these marine microbes, and will reveal how understanding their ecology is essential for predicting the consequences of an over-exploited ocean and its impact on climate change.
UTS科学聚焦：海洋微生物：海洋的命脉？
如何做这些极小的微生物有助于海洋功能以及他们如何应对气候变化？
超过70％的地球被水覆盖着海洋，但是当我们觉得生活在海洋中，我们通常认为的鱼，鲨鱼和鲸鱼 - 生活，是可见的肉眼。你会惊讶地得知，大多数生活在海洋中的微生物 - 微小的，看不见的生物！
超过90 ％的海洋生物量是由海洋微生物组成。所以，它们是什么？它们包括海洋的细菌，病毒和藻类。他们也是地球上最多样和丰富的生物。他们是在海洋中的作用至关重要，因为他们是我们的海洋食物网的基础，是非常重要的保护生态系统功能和支持渔业生产。这些微小的海洋微生物，甚至通过驱动地球的主要化学循环影响我们的气候。
玛蒂娜博士德布林和Justin西摩博士研究中的作用和研究这些海洋微生物的挑战，以及将揭示如何理解它们的生态环境是预测的过度捕捞海洋及其对气候变化的影响的后果至关重要
