Our oceans are changing. Elevated greenhouse gases caused the increase of Earth’s average temperature (or global warming) and contributed to what we now know as climate change. This in turn has a big influence on the oceans and the organisms that live in them. Given that oceans are changing so rapidly, how are marine organisms affected by this? Can they adapt? How can we study those adaptations? Where should we start?

In between Africa and Asia, in the Middle East region, lies a vast mass of seawater connected to the Indian ocean by its southern end. This water body is called the Red Sea, some say because of the presence of a reddish-brown cyanobacteria in its waters, others say because red was the color representing “south” (of the Mediterranean civilization) in ancient times. Its location makes it a unique environment with high temperatures and salinities (the amount of salt dissolved in water), creating a complex environmental gradient from north to south in its more than two thousand kilometers of length. Despite these harsh, almost alien conditions, the Red Sea is home to large green mangroves and seagrass meadows, more than a thousand species of fish (many of them unique to the Red Sea), hundreds of species of corals and countless invertebrates. At the microscopic level, we make new discoveries every day so that our knowledge on the diversity of bacteria, microalgae, and viruses is constantly increasing.

But if it is so difficult to sustain life in the Red Sea, how do all these organisms still prosper in it? This is one of many questions scientists are trying to answer by studying how abiotic factors such as temperature, salinity and nutrients of the Red Sea can affect its organisms (or biota). Moreover, due to its extreme conditions, the Red Sea can also act as a unique laboratory to study and learn about the future impacts of climate change on ecosystems: it represents a time machine that allows us to look into the future of tropical oceans and lets us understand how organisms thrive in environmental extremes.

The aim of this collection is to explore the current knowledge we have on the Red Sea biodiversity and its adaptability to environmental change. From coral reefs and the mutual beneficial relationships (symbiosis) between organisms, to seagrasses and brine pools, we aspire to learn how life can find a way to flourish even when the odds seem to be against it. More importantly, by understanding the present conditions of the Red Sea, we might be able to predict how organisms from other regions will adapt to fast changing climate."> 地球上一个陌生的地方:红海作为年轻的模型对未来海洋·前沿思想 - 万博体育max官网登录

关于这个集合

我们的海洋正在改变。升高的温室气体导致地球平均温度的增加(或全球变暖),导致了我们现在所知的气候变化。这反过来有很大影响海洋和生物生活在他们。鉴于海洋变化如此之快,海洋生物受此影响怎么样?他们能适应吗?我们如何研究这些适应性?我们应该从哪里开始呢?

在非洲和亚洲,中东地区,是一个巨大的海水质量连接到印度洋南端。这个水体叫红海,有人说因为红褐色的存在在其水域蓝藻,也有人说因为红颜色代表“南”(地中海文明)在古代。其地理位置使其成为一个独特的环境温度和盐度高(盐在水中溶解的量),创建一个复杂的环境梯度从北到南二千多公里的长度。尽管有这些苛刻,几乎陌生的条件,红海是大型绿色红树林和海草,超过一千种鱼类(其中许多独特的红海),数百种珊瑚和无数的无脊椎动物。在微观层面,我们天天新发现,这样我们的知识多样性的细菌、微藻,病毒不断增加。

但如果它是如此难以维持生活在红海,所有这些生物如何仍然繁荣吗?这是许多科学家正在试图回答的问题研究非生物因素,如温度、盐度和营养的红海会影响其生物(或生物)。此外,由于它的极端条件下,红海也可以作为一个独特的实验室研究和学习对未来气候变化对生态系统的影响:它代表了时间机器,让我们展望未来的热带海洋和让我们了解生物生长在极端环境。

本系列的目的是探索当前知识我们在红海的生物多样性和环境变化的适应性。从珊瑚礁和生物之间的互利关系(共生),海草和卤水池,我们渴望学习生活可以找到一种方法来繁荣即使几率似乎反对它。更重要的是,通过了解红海的现状,我们可以预测生物从其他地区将如何适应快速变化的气候。
