概括

在特拉华湾观察到浮游生物的季节性变化. 海洋II组古生物在夏季丰富,而冬季则由甲基生物占主导地位,突出显示了河口微生物生态.

科学领域:

河口生态学河口生态学
微生物生态学微生物生态学
生物地质化学生物地质化学

背景情况:

沿海海湾是连接河流和海洋的重要,富有生产力的生态系统.
潮周期和变化的有机物质为微生物生命创造了动态的条件.
了解考古社区是河口健康的关键.

研究的目的:

在潮河口环境中调查考古组合的季节性动态.
为了将考古群丰富与环境因素和粒子大小相关联.
为了阐明浮游生物在河口中的生态作用.

主要方法:

长达一年的,按大小分成部分的时间序列抽样.
用于考古社区分析的安普利康序列.
环境环境中的定量PCR (qPCR) 和化学测量.

主要成果:

海洋II组古生物在夏季达到峰值,这与植物浮游生物生产指标有关.
在冬季低潮期间,甲基生物在大颗粒中普遍存在.
与之前的研究相反,发现纳米archaeia是自由生活的,而不是与宿主相关的.

结论:

河口时间序列研究对于理解浮游生物的考古生态学至关重要.
季节性变化对考古物种的分布和丰富程度有重大影响.
这些发现挑战了关于河口系统中古代生活方式的现有假设.

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.
