“光：营养假说”（LNH）指出，微生物食物网相对于大型浮游动物放牧影响的重要性以及藻类和细菌之间关系的性质（竞争或共生）受到浮游植物经历的光和营养平衡的影响。我们测试了这一假设，在现场外壳操纵辐照度和营养供应在加拿大安大略的磷限制湖。遮荫和富磷对小颗粒悬浮物生物量的影响不大，
The 'light:nutrient hypothesis' (LNH) states that the importance of the microbial food web relative to grazing impacts by macrozooplankton and the nature of the relationship between algae and bacteria (competition or commensalism) are affected by the balance of light and nutrients experienced by phytoplankton. We tested this hypothesis in field enclosures by manipulating irradiance and nutrient supply in a P-limited lake in Ontario, Canada. Shading and P-enrichment had little effect on standing biomass of small suspended particles (
