本研究探讨夏威夷岛东南部阿威岛潮池的珊瑚Montipora capitata生长异常的形态、严重程度与分布。骨骼微结构的宏观图像分析将GA分为两个可定义的类别：A型和B型。与健康M相比，A型GA的息肉密度降低了43.05 +/- A 0.80%（平均+/- A SE）。头状组织，具许多融合和隆起的瘤。B型GAs没有可辨别的息肉或杯，融合突起的共骨。A型和B型GAs在M.在阿威湾8个潮池中的capitata菌落（n = 1，093）分别为22.1%（2.8-33.7%）和8.2%（0.0-16.9%）。对GA占据的菌落表面积的比例（相对GA覆盖率）进行定量，以评估在所有调查的菌落中该疾病的严重程度。相对GA覆盖是显着大于1米直径的殖民地比较小的殖民地和殖民地的中心部分比在周边更大。GA相对覆盖度与水体运动呈负相关（R（2）= 0.748，P < 0.01）。制定了M. capitata GA允许进行详细的动物流行病学评估，确定与疾病严重程度相关的几个辅因子。这种动物流行病学分析适用于其他地方未来的GA研究。
This study investigated the morphology, severity, and distribution of growth anomalies (GAs) in the coral, Montipora capitata, from Wai'Aipae tide pools, southeast Hawai'i Island. A macro-image analysis of skeletal microstructure placed GAs into two definable categories; Type A and Type B. Type A GAs had polyp density reduced by 43.05 +/- A 0.80% (mean +/- A SE) compared to healthy M. capitata tissue, with many fused and protrusive tuberculae. Type B GAs had no discernable polyps or calices and fused protuberant coenosteum. The prevalence of Type A and Type B GAs among all M. capitata colonies (n = 1,093) in 8 tide pools at Wai'Aipae was 22.1% (range 2.8-33.7%) and 8.2% (range 0.0-16.9%), respectively. The proportion of colony surface area occupied by GA (relative GA cover) was quantified to assess the severity of this disease among all surveyed colonies. The relative GA cover was significantly greater on colonies larger than 1 m in diameter than smaller colonies and in the central portion of colonies than in the periphery. Furthermore, relative GA cover was negatively related to water motion (R (2) = 0.748, P < 0.01). Developing field diagnostic criteria of M. capitata GA allowed for a detailed epizootiological assessment that determined several cofactors associated with disease severity. Such epizootiological analysis is applicable to future studies of GAs elsewhere.
