This PhD Project aims at developing a reliable and robust monitoring system that will provide comprehensive information about the status of the coastal marine ecosystem off Southwest England, combining bottom-up and top-down approaches and consequently providing a better approximation to mid-trophic level species of economic importance. The project directly addresses the sustainable management of resources, particularly pelagic and demersal fisheries, as it will provide evidence from a combination of sources (remote sensing and top predators) that will identify stressors that can impact the trophic fluxes across the coastal marine ecosystem, where anthropogenic extractive activities have a larger impact. We anticipate that our project will render effective tools that will support monitoring activities and will help detect regional anomalies that have an impact on managed resources (e.g., shifts in the primary productivity regimes, changes in the community composition of primary producers, Harmful Algal Blooms (HAB) events, and losses and changes in the magnitude of trophic links in the food web, among others). Ultimately, this project will increase the amount of ecological-relevant information that we can obtain from readily available samples that can easily be obtained at low costs, positively impacting our ability to identify ecosystem-wide variations, enhancing our capacity to respond to these, and improving our sustainable management strategies.

该博士学位项目旨在开发可靠，可靠的监测系统，该系统将提供有关英格兰西南部沿海海洋生态系统状况的全面信息，结合了自下而上的和自上而下的方法，并因此提供了对中型中部经济重要性物种的更好近似。该项目直接解决了资源的可持续管理，尤其是上层渔业，因为它将提供来自来源（遥感和顶级捕食者）组合的证据，这些证据将识别出可能影响沿海海洋生态系统的营养通量的压力源，在该系统中，人类发育性活动具有更大的影响。我们预计我们的项目将提供有效的工具，以支持监视活动，并有助于检测影响托管资源的区域异常（例如，主要生产率的转变，主要生产商的社区组成，有害藻类布鲁姆斯（HAB）事件的变化，以及食物网络中滋养链接的幅度的变化）。最终，该项目将增加我们可以从便捷的样本中获得的与生态相关的信息的数量，这些信息可以轻松以低成本获得，从而积极影响我们识别生态系统范围内的变化的能力，增强了我们对这些变化的响应能力，并改善了我们的可持续管理策略。
