Investing in ecological portfolios: retaining migratory strategies of fish

在金融领域，投资者通过建立不同属性的股票投资组合，将风险降到最低，并优化长期回报。这种应急策略也出现在生态系统中。我们将使用组合效应作为概念模型来描述鲜为人知的河口鱼类迁徙策略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移策略的变化，影响长期增长和人口营养网动态。结果将促进新的和动态的管理框架，提高人口稳定，尽管预测的环境条件的波动。

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.
