谁在做饭，谁在打扫卫生，谁在覆盖地球的沃茨中掌握着遥控器？解剖学上微小的、数量上占优势的微生物是水家庭的关键“主妇”。浮游植物的烹饪能力使它们能够通过吸收阳光来固定碳并释放氧气来创造食物，使微生物自养生物成为水生厨房的顶级厨师。然而，他们并不是唯一平衡这个复杂家庭的生物工程师。普遍存在的异养微生物包括原核细菌和古生菌（以下均为“细菌”）、真核原生生物和病毒，它们回收有机物质并使无机营养物可用于初级生产者。食草原生生物与病毒竞争细菌生物量，而兼养原生生物产生新的有机物质以及消耗微生物生物量。当病毒按下遥控按钮时，通过修改宿主基因组或裂解它们，结果可以在整个微生物群落中产生反响。尽管认识到微生物在生物圈管家中的重要作用，但人类压力和气候变化对其生物多样性，进化和生态功能的影响仍然知之甚少。在地球最大的生态系统中，数万亿最小的有机体如何反应将产生巨大的影响。通过使生态学的研究个人化，“管家”的观点可以更好地了解在所有尺度上不断变化的生态系统结构和功能。
Who’s cooking, who’s cleaning, and who’s got the remote control within the waters blanketing Earth? Anatomically tiny, numerically dominant microbes are the crucial “homemakers” of the watery household. Phytoplankton’s culinary abilities enable them to create food by absorbing sunlight to fix carbon and release oxygen, making microbial autotrophs top-chefs in the aquatic kitchen. However, they are not the only bioengineers that balance this complex household. Ubiquitous heterotrophic microbes including prokaryotic bacteria and archaea (both “bacteria” henceforth), eukaryotic protists, and viruses, recycle organic matter and make inorganic nutrients available to primary producers. Grazing protists compete with viruses for bacterial biomass, whereas mixotrophic protists produce new organic matter as well as consume microbial biomass. When viruses press remote-control buttons, by modifying host genomes or lysing them, the outcome can reverberate throughout the microbial community and beyond. Despite recognition of the vital role of microbes in biosphere housekeeping, impacts of anthropogenic stressors and climate change on their biodiversity, evolution, and ecological function remain poorly understood. How trillions of the smallest organisms in Earth’s largest ecosystem respond will be hugely consequential. By making the study of ecology personal, the “housekeeping” perspective can provide better insights into changing ecosystem structure and function at all scales.
