浮游活性物质

Planktonic Active Matter

Anupam Sengupta

摘要:

浮游活性物质代表了一个跨越不同尺度的新兴系统:个体、种群和群落;以及从亚细胞和细胞到集体和生态系统尺度动态的复杂性。这种跨尺度的活性物质系统对一系列非生物因素(温度、流体流动和光照条件)和生物因素(养分、pH值、次级代谢物)作出反应,这些因素是它们所属的相关生态系统的特征。细胞表型的主动调节,包括形态、运动性和细胞内组织,使嗜热微生物能够与其他个体和物种动态地相互作用;并适应-通常迅速-环境的变化。在这一章中,我讨论了传统和当代的方法来研究这个多尺度的活性物质系统的动态从机械的角度来看,具体参考他们的本地设置和他们的能力,积极调整的行为和生理,以及新兴的结构和功能,他们引起自然生态的限制,以及由于气候变化的趋势。

英文摘要:

Planktonic active matter represents an emergent system spanning different scales: individual, population and community; and complexity arising from sub-cellular and cellular to collective and ecosystem scale dynamics. This cross-scale active matter system responds to a range of abiotic (temperature, fluid flow and light conditions) and biotic factors (nutrients, pH, secondary metabolites) characteristic to the relevant ecosystems they are part of. Active modulation of cell phenotypes, including morphology, motility, and intracellular organization enable planktonic microbes to dynamically interact with other individuals and species; and adapt - often rapidly - to the changes in their environment. In this chapter, I discuss both traditional and contemporary approaches to study the dynamics of this multi-scale active matter system from a mechanistic standpoint, with specific references to their local settings and their ability to actively tune the behaviour and physiology, and the emergent structures and functions they elicit under natural ecological constraints as well as due to the shifting climatic trends.
