Trophic cascades in Australian seagrasses: linking nutrients to survival and growth of commercially-important fishes

尽管海草具有很高的保护地位，对商业和休闲渔业也很重要，但澳大利亚水域的海草数量仍在下降。通过研究将营养物污染与海草和具有重要商业价值的幼鱼的生长和存活联系起来的营养级联，我们的研究填补了对改善未来海草栖息地管理至关重要的知识空白。这项研究的主要结果将是一个模型，可以预测营养污染的变化将如何影响海草支持的重要商业鱼类物种的种群动态。因此，这些资料与地方、州和联邦各级政府河口和海岸环境管理人员有直接关系。

Despite its high conservation status and importance to commercial and recreational fisheries, seagrass is still declining in Australian waters. By investigating a trophic cascade that links nutrient pollution to the growth and survivorship of seagrass and commercially-important juvenile fishes, our study fills knowledge gaps crucial for improved future management of seagrass habitats. The primary outcome of this study will be a model that can predict how changes in nutrient pollution will influence population dynamics of commercially-important fish species supported by seagrass. This information has, therefore, direct relevance to managers of estuarine and coastal environments at all levels of government - local, state and federal.
