Food Web Structure in the Arabian Sea: Phytoplankton and Microzooplankton Studies as Part of the US JGOFS Arabian Sea Study

9310634作为美国联合海洋研究组织阿拉伯海过程研究的一部分，这项研究旨在了解初级生产者、浮游动物捕食者和微型异养分解者等远洋群落物种组成和丰度的变化如何影响阿拉伯海碳的生化循环。季风风的物理强迫触发了该地区生物生产力的季节性爆发。正如在其他生态系统中一样，这种生产将涉及生产者、食草动物和分解者物种的时间演替--每个物种都具有不同的能力来影响碳的产生、呼吸、物理重新包装(例如，粉碎、粪便颗粒生产)和运输--PIs建议随着时间的推移跟踪这些变化。因此，尽管参与ASPS的其他研究人员将对碳产生、矿化和运输的速率进行相对粗略的化学测量，但这项研究将为解释这些速率的特定生物物理和生态机制的实际贡献提供有价值的见解。

9310634 GOWING As part of the U.S. JGOF Arabian Sea Process Study (ASPS), this study is aimed at understanding how changes in species composition and abundance in the pelagic community of primary producers, zooplankton grazers, and microheterotrophic decomposers impacts the biochemical cycling of carbon in the Arabian Sea. Physical forcing by the monsoon winds triggers seasonal burst of biological productivity in this region. As in other ecosystems, this production will involve a temporal succession of species of producers, grazers, and decomposers-- each with differing capacities to influence carbon production, respiration, physical repackaging (e.g., shredding, fecal pellet production), and transport-- and the PIs propose to follow these changes over time. Therefore, while other investigators involved in the ASPS, will be making relatively gross chemical measurements of the rates of carbon production, mineralization, and transport, this study will provide valuable insights into the actual contributions of specific biophysical and ecological mechanisms accounting for those rates.
