海洋学海洋学海洋学
分子生态学分子生态学

背景情况:

中原浮游生物对海洋碳循环和能量转移至关重要.
全球对中动物浮游生物多样性,分布和连接性的知识是分散的.
了解这些社区对于预测海洋生态系统反应至关重要.

研究的目的:

通过使用DNA元编码来评估全球半动物浮游生物的多样性和分布.
确定海洋地区具有重要的未被发现的生物多样性.
为了研究构建深度和盆地的中动物浮游生物群落的因素.

主要方法:

来自马拉斯皮纳-2010环球航行中的中动物浮游生物样本的DNA元编码.
跨大西洋,印度洋和太平洋从表面到海水区的分析.
检查alpha和beta多样性模式和社区结构.

主要成果:

证实了全球内生浮游生物多样性知识的重大差距.
印度洋和深海拥有最高比例的隐藏多样性.
中生浮游生物群体表现出横向和垂直的结构,增大了贝塔多样性,与深度的连接性减少.
浴群落是由水质类型构成的,不同于由海洋盆地构成的上层.
建议在深海层中进行有限的分散,受潮流和水质混合的影响.

结论:

全球半动物浮游生物的多样性被低估了,印度洋和深海的关键热点.
深度和水质类型是深海中中生浮游生物群体结构的关键驱动因素.
海流和海洋障碍在塑造全球浮游生物连接方面发挥着重要作用,特别是在更深的水域.

Primary Production

Primary Production

The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.

Plasmodesmata

Plasmodesmata

In a multicellular organism, cells must communicate to work together in a coordinated manner. One way that cells communicate is through direct contact with other cells. The points of contact that connect adjacent cells are called intercellular junctions.
Intercellular junctions are a feature of fungal, plant, and animal cells. However, different types of junctions are found in different kinds of cells. Intercellular junctions found in animal cells include tight junctions, gap junctions, and...
