在过去的十年中，volvocine绿色藻类，从单细胞的衣原体到多细胞团藻，已经成为生物流体动力学中许多问题的模型生物。这些包括鞭毛推进，营养吸收的游泳生物，介导的墙壁，集体动力学和运输悬浮液内的microswimmer，趋光性的机制，和随机动力学的鞭毛同步的流体动力学的相互作用。绿色藻类非常适合研究这些问题，因为它们的大小范围（从10微米到几毫米），它们的几何规则性，它们可以培养的容易性和许多突变体的可用性，允许分子细节和生物体水平行为之间的联系。本文综述了这些最新的发展，并强调了有前途的未来方向，在生物流体动力学的研究，特别是在进化生物学的背景下，可以利用这些显着的生物体。
In the past decade the volvocine green algae, spanning from the unicellular Chlamydomonas to multicellular Volvox, have emerged as model organisms for a number of problems in biological fluid dynamics. These include flagellar propulsion, nutrient uptake by swimming organisms, hydrodynamic interactions mediated by walls, collective dynamics and transport within suspensions of microswimmers, the mechanism of phototaxis, and the stochastic dynamics of flagellar synchronization. Green algae are well suited to the study of such problems because of their range of sizes (from 10 μm to several millimetres), their geometric regularity, the ease with which they can be cultured and the availability of many mutants that allow for connections between molecular details and organism-level behavior. This review summarizes these recent developments and highlights promising future directions in the study of biological fluid dynamics, especially in the context of evolutionary biology, that can take advantage of these remarkable organisms.
