The dynamics and restoration ecology of marine ecosystems

从长远来看，本研究旨在通过验证基于全生态系统模拟模型的假设，为海洋恢复生态学建立新的理论。我的工作中的恢复是基于对过去生态系统状态的历史重建，受气候和其他地球化学驱动因素的影响。迄今为止，这项工作已经公布了生态系统的理论基线，因为它们可能没有捕鱼提取，理论上的捕鱼船队没有丢弃物或副渔获物，以及在恢复期间继续积累效益的恢复轨迹。在短期内，接下来的两个理论步骤是，首先，分析与食物和捕食者相关的饲料鱼产量的上限和下限，并研究中营养水平的物种如何影响这些限制。其次，我将研究浮游动物食物网的复杂性如何影响更高营养水平的生产：这将特别提供在许多海洋生态系统中观察到的“政权转移”的见解。从长远来看，我的工作将试图建立进一步的理论，为渔业生态系统的恢复生态学提供参考点，这些参考点可以很容易和实际地估计，并显示出可以测量达到的程度的方法。

In the long term, this proposal aims to establish fresh theory for marine restoration ecology by testing hypotheses based on whole-ecosystem simulation models fitted to a diversity of case study ecosystems. Restoration in my work is based on the historical reconstruction of past ecosystem states, as affected by climate and other geochemical drivers. To date, this work has published theoretical baselines for ecosystems as they may have been with no fishing extractions, for fishing with theoretical fleets that have no discards or bycatch, and a restoration trajectory that continues to accrue benefits during the restoration period. In the short term, the next two theoretical steps are, first, to analyze upper and lower limits to forage fish production in relation to food and predators, and to investigate how speciosity in the mid trophic levels affects these limits. Second, I will examine how complexity in zooplankton food webs impacts production at higher trophic levels: this will especially provide insight of the 'regime shifts' that have been observed in many marine ecosystems. In the longer term, my work will attempt to establish further theory that will provide reference points for the restoration ecology of fisheries ecosystems that can be easily and practically estimated and show ways in which the extent to which they are attained can be measured.
