白化珊瑚与健康邻体接触数天内即可恢复

斯坦福大学研究团队发现，将白化珊瑚与健康珊瑚片段接触，可在数天内快速恢复珊瑚颜色。1这项研究成果已于2025年10月14日发表在《Science Advances》上。1实验表明，当相同遗传个体的珊瑚片段相互接触时，会形成组织桥，使共生藻转移到白化珊瑚上。1在接触后的两周内，白化珊瑚上的共生藻种群数量每四天翻倍，白化珊瑚在8周内实现完全恢复。1

研究进一步发现，白化珊瑚与健康片段接触一周后，即使两者随后分离，白化珊瑚仍能继续独立恢复。1相比之下，未接触健康珊瑚的对照组白化珊瑚在20周后死亡。1值得注意的是，组织融合仅发生于相同遗传个体的珊瑚片段之间，不同物种或不同个体的珊瑚片段无法融合。1这一发现为大规模珊瑚恢复提供了新的可能性。

Researchers at Stanford University have discovered a remarkably swift recovery mechanism for bleached corals through direct contact with healthy coral fragments. When bleached coral tissue touches segments from the same genetic individual, a tissue bridge forms that enables symbiotic algae to transfer to the damaged coral, restoring its coloration within weeks 1.

The study, published in Science Advances on October 14, 2025, demonstrated that bleached corals achieved complete recovery within eight weeks of contact with healthy fragments 1. During the second week following initial contact, the population of symbiotic algae doubled every four days 1. Remarkably, bleached corals separated from their healthy neighbors after just one week of contact continued to recover independently, suggesting the transferred algae established themselves successfully 1. In contrast, bleached corals in the control group that received no contact with healthy tissue died within 20 weeks 1.

The research team, including Danny Collins and Stephen Palumbi, conducted experiments at Stanford's Hopkins Marine Station in Pacific Grove, California 1. A critical finding was that tissue fusion and algae transfer occurred only between fragments of the same genetic individual; coral pieces from different species or different individuals failed to fuse 1. These results offer new possibilities for large-scale coral restoration efforts by harnessing natural recovery pathways.
