自从苏珊·威廉姆斯和我在20世纪70年代中期开始我们的科学生涯以来,海草科学已经从一个主要是描述性的领域转变为一个越来越多的定量和预测性的努力,需要对控制能量同化、生长和繁殖的代谢网络的环境影响有一个机制的理解。虽然环境对基因产物的潜在影响是无数的,但重要的表型反应通常由代谢网络中的几个关键点调节,其中外部供应的资源或生理底物限制了反应动力学。通常限制海草生产力、生存和生长的环境资源包括光、温度和co2有效性,它们控制着碳同化和蔗糖形成,并调节对环境变化的应激反应。在这里,我提出了一种系统方法来量化海草对气候变化背景下控制基本生理过程和整个植物性能的环境因素变化的反应。这一综述表明,我们了解海草生态系统的过去和预测未来轨迹的能力,可以受益于对这些重要植物对海洋酸化、气候变暖和富营养化同时影响的反应的机制理解,这些影响正在改变全球生态系统的功能。
Since Susan Williams and I started our scientific careers in the mid-1970s, seagrass science has been transformed from a largely descriptive field to an increasingly quantitative and predictive endeavor that requires a mechanistic understanding of environmental influence on metabolic networks that control energy assimilation, growth, and reproduction. Although the potential impacts of environment on gene products are myriad, important phenotypic responses are often regulated by a few key points in metabolic networks where externally supplied resources or physiological substrates limit reaction kinetics. Environmental resources commonly limiting seagrass productivity, survival, and growth include light, temperature, and CO2availability that control carbon assimilation and sucrose formation, and regulate stress responses to environmental change. Here I present a systems approach to quantify the responses of seagrasses to shifts in environmental factors that control fundamental physiological processes and whole plant performance in the context of a changing climate. This review shows that our ability to understand the past and predict the future trajectory of seagrass-based ecosystems can benefit from a mechanistic understanding of the responses of these remarkable plants to the simultaneous impacts of ocean acidification, climate warming, and eutrophication that are altering ecosystem function across the globe.
