Suspension feeding animas are ubiquitous in aquatic habitats and exert major effects on aquatic ecosystems. This interdisciplinary project will use hydrodynamic theory as an explanatory tool to predict how organism size and the physical properties of water, such as temperature, may influence feeding by this key functional group in situations not addressed by current theory. The project involves integrating both experiment and modelling at the interface between ecology, engineering, and physics. Suspension feeding represents convergence in feeding structures and mode on a massive scale across almost all phyla, convergence that we are currently unable to explain because we lack knowledge of the basic physics involved in the feeding process.

悬浮性摄食动物普遍存在于水生生境中，对水生生态系统产生重要影响。这个跨学科的项目将使用水动力学理论作为一种解释工具，以预测在当前理论没有解决的情况下，生物体的大小和水的物理性质，如温度，可能如何影响这一关键功能群的摄食。该项目涉及在生态学、工程学和物理学之间的界面上整合实验和建模。悬浮摄食代表了几乎所有门在摄食结构和方式上的大规模收敛，我们目前无法解释这种收敛，因为我们缺乏摄食过程中涉及的基本物理知识。
