过去二十年来，珊瑚白化（共生甲藻丧失）和珊瑚死亡的发生频率越来越高。虽然一些珊瑚从白化事件中恢复过来，但共生体的来源尚不清楚。在这里，我们表明，漂白后，成年珊瑚Briareum sp。收购甲藻共生体（Symbiodinium sp。）从环境中。吸收外源性共生体提供了一种机制，以应对环境的变化和共生的弹性。
Episodes of coral bleaching (loss of the symbiotic dinoflagellates) and coral mortality have occurred with increasing frequency over the past two decades. Although some corals recover from bleaching events, the source of the repopulating symbionts is unknown. Here we show that after bleaching, the adult octocoral Briareum sp. acquire dinoflagellate symbionts (Symbiodinium sp.) from the environment. Uptake of exogenous symbionts provides a mechanism for response to changes in the environment and resilience in the symbiosis.
