Abstract

Many published coral disease pathogen transmission and heat stress studies lack consistent acclimation periods in their experimental design, making it difficult to interpret or compare results between studies. To determine if condition of coral tissue changes during laboratory acclimation, thus potentially influencing susceptibility to stressors, we conducted a histological analysis on fragments of the Caribbean staghorn coral, Acropora cervicornis, during a 9-day acclimation period. We found a significant decline in overall condition between clippings taken initially and on day 2, and significant improvements in two key surface body wall parameters from day 2 to day 9. These findings indicate that A. cervicornis has a delayed response to new environmental conditions and therefore needs at least a 4-day acclimation period, and when possible, 9 days or more prior to experimentation.

适应期影响加勒比鹿角珊瑚 Acropora cervicornis 的组织状况

摘要许多已发表的珊瑚疾病病原体传播和热应力研究的实验设计中缺乏一致的适应期，因此很难解释或比较不同研究的结果。为了确定珊瑚组织的状况是否会在实验室适应期间发生变化，从而可能影响对应激源的易感性，我们对加勒比鹿角珊瑚 Acropora cervicornis 在 9 天适应期的碎片进行了组织学分析。我们发现，在最初和第 2 天所取的片段之间，珊瑚的整体状况明显下降，而从第 2 天到第 9 天，珊瑚体壁的两个关键参数有了明显改善。这些研究结果表明，鹿角鲷对新环境条件的反应具有延迟性，因此至少需要 4 天的适应期，如果可能，在实验前需要 9 天或更长时间。

期刊介绍： Coral Reefs, the Journal of the International Coral Reef Society, presents multidisciplinary literature across the broad fields of reef studies, publishing analytical and theoretical papers on both modern and ancient reefs. These encourage the search for theories about reef structure and dynamics, and the use of experimentation, modeling, quantification and the applied sciences. Coverage includes such subject areas as population dynamics; community ecology of reef organisms; energy and nutrient flows; biogeochemical cycles; physiology of calcification; reef responses to natural and anthropogenic influences; stress markers in reef organisms; behavioural ecology; sedimentology; diagenesis; reef structure and morphology; evolutionary ecology of the reef biota; palaeoceanography of coral reefs and coral islands; reef management and its underlying disciplines; molecular biology and genetics of coral; aetiology of disease in reef-related organisms; reef responses to global change, and more.
