Coral diseases acting synergistically with other environmental stressors are a growing problem for Caribbean reefs. Hard coral cover, coral traits, and coral diseases were examined from 1999 to 2021 for Akumal reef, located in the Northern Mexican Caribbean. The 45 recorded coral species were classified into life-history strategies: competitive, stress-tolerant, and weedy, associated with different framework-building capacities. Results indicate that cumulative impacts of coral diseases outbreaks in the last two decades, in synergy with the effects of coastal development and thermal stressors, have decreased significantly cover and abundance of major reef-building corals, shifting the dominance of the coral assemblage to species belonging to non-framework weedy life history strategy, corresponding to a low Reef Functional Index. Due to the relevant role of coral diseases in shaping coral assemblages, addressing current, and preventing future coral disease outbreaks through integrated management strategies, will be paramount to preserving physical functionality in Caribbean reefs.

23 年来,珊瑚病在加勒比珊瑚礁变平中的作用

珊瑚病与其他环境压力因素协同作用是加勒比珊瑚礁日益严重的问题。从 1999 年到 2021 年,我们对位于墨西哥北部加勒比海的 Akumal 礁进行了硬珊瑚覆盖、珊瑚特征和珊瑚病检查。记录的 45 种珊瑚物种被分为生活史策略:竞争性、耐压性和杂草性,与不同的框架建设能力相关。结果表明,在过去二十年中,珊瑚病爆发的累积影响与沿海发展和热应激源的影响相结合,显着减少了主要造礁珊瑚的覆盖率和丰度,将珊瑚群落的主导地位转移到属于到非框架杂草生活史策略,对应于低珊瑚礁功能指数。
