局部规模的营养物质污染会改变珊瑚的生长和繁殖产出，以及它们居住的微生物群落(共生科细菌中的甲藻)。然而，营养污染如何改变珊瑚与其微生物的相互作用还没有完全了解，也没有研究测试营养胁迫对珊瑚全叶生物的跨代影响。为了研究这一点，在原位用硝酸盐富集尖头螺菌落长达一年，并监测其平整情况。成虫的基因表达、栖息的微生物群落和全息性特征与浮萍的基因表达、栖息微生物群落和全息性特征相同。虽然被 >； 分隔了5米，但在大多数珊瑚群体中观察到了克隆和嵌合体。在成虫和幼虫中检测到硝酸盐处理的谱系和处理的特定效果。富含硝酸盐的成虫含有较高密度的共生菌科植物，并显示出参与含氮化合物合成的基因下调。与成虫相比，平腹鱼具有更高的共生菌科和细菌多样性；这项研究构成了对这些来自单个平腹鱼的微生物的第一次评估。珊瑚伴生细菌群落以内生单胞菌为主，不受营养处理的影响。与浮萍相关的细菌群落与其亲本不同，但与亲本接触营养物质的情况不同，富集物对繁殖力或定居成功的影响不会产生变化。综上所述，这些发现表明，成年珊瑚通过拥有更高的共生科密度来适应长期的营养污染，对后代没有观察到的负面影响。
Local-scale nutrient pollution can alter coral growth and reproductive output, as well as their resident communities of microorganisms (dinoflagellates in the family Symbiodiniaceae, bacteria). Yet, the ways in which nutrient pollution alters coral interactions with their microorganisms are not fully understood, and no studies have tested for transgenerational impacts of nutrient stress on coral holobionts. To investigate this, colonies ofPocillopora acutawere enriched with nitrate in situ for up to one year and monitored for planulation. Gene expression, resident microbial communities and holobiont traits were characterized in adults, as well as in planulae. Although separated by > 5 m, clonality and chimerism were observed in the majority of coral colonies. Lineage- and treatment-specific effects of nitrate treatment were detected in adults and planulae. Nitrate-enriched adults contained higher densities of Symbiodiniaceae and exhibited downregulation of genes involved in the synthesis of nitrogenous compounds. Planulae harbored higher Symbiodiniaceae and bacteria diversity than adults; this study constitutes the first assessment of these microorganisms from individual planulae. Coral-associated bacteria communities wereEndozoicomonas-dominated and were not altered by nutrient treatment. Planula-associated bacteria communities differed from their parents but not from parental exposure to nutrients, and no changes in fecundity or settlement success resulted from enrichment. Taken together, these findings suggest that adult corals acclimate to chronic nutrient pollution by harboring higher Symbiodiniaceae densities, with no observed negative effects on the subsequent generation.
