In finance, investors minimize risk and optimize long term returns by building stock portfolios with different attributes. This contingency strategy also occurs in ecological systems. We will use portfolio effects as a conceptual model to characterise the poorly known sub-population variations in migratory strategies of estuarine fish and their response to environmental conditions. In doing so, we will determine how environmental change drives variations in migratory strategies, impacts long-term growth and population trophic web dynamics. Outcomes will foster novel and dynamic management frameworks that enhance population stability despite the predicted volatility of environmental conditions.

在金融领域，投资者通过建立具有不同属性的股票投资组合来最大限度地降低风险并优化长期回报。这种应急策略也发生在生态系统中。我们将使用组合效应作为概念模型来描述河口鱼类洄游策略中鲜为人知的亚种群变化及其对环境条件的响应。在此过程中，我们将确定环境变化如何驱动迁徙策略的变化，影响长期增长和种群营养网动态。成果将培育新颖和动态的管理框架，尽管预计环境条件会发生波动，但仍可增强人口稳定性。
