Habitat degradation induced by human activities can exacerbate the spread of wildlife disease and could hinder the recovery of imperiled species. The endangered green turtle Chelonia mydas is impacted worldwide by fibropapillomatosis (FP), a neoplastic infectious disease likely triggered by the Scutavirus chelonidalpha5 with coastal anthropogenic stressors acting as cofactors in disease development. Here, we studied fibropapillomatosis dynamics and its demographic consequences using an 11-year capture-mark-recapture dataset in Anse du Bourg d'Arlet/Chaudière (ABAC) and Grande Anse d'Arlet (GA), two juvenile green turtle foraging grounds in Martinique, French West Indies. Afflicted turtles had similar mortality and permanent emigration rates to the non-afflicted ones. Fibropapillomatosis was commonly observed in large individuals and disease recovery may take several years. Consequently, permanent emigration before full recovery from the disease is suspected and might affect the developmental migration success. Additionally, the results revealed that the FP had higher prevalence and severity, and progressed two times faster in ABAC than in GA despite the proximity (< 2 km) and the similarity of the two foraging grounds. The reasons for these differences remain unidentified. Locally, further studies should be focused on the determination of the external and internal cofactors related to the observed FP dynamics. Finally, the investigations should be extended at a global regional scale to determine potential deleterious effect of the FP on the adult life-stage. These perspectives improves upon our overall understanding on the interplay between wildlife diseases, hosts and environmental factors.
人类活动导致的栖息地退化会加剧野生动物疾病的传播，并可能阻碍濒危物种的恢复。濒危绿海龟蠵龟在全球范围内受到纤维乳头瘤病（FP）的影响，这是一种肿瘤性传染病，可能由蠵龟甲型5病毒引发，沿海人为压力因素在疾病发展中起辅助作用。在这里，我们利用在法属西印度群岛马提尼克岛的两个绿海龟幼龟觅食地——安斯迪布尔戈达莱特/肖迪埃（ABAC）和大安斯迪布尔戈达莱特（GA）——收集的11年标记重捕数据集，研究了纤维乳头瘤病的动态及其对种群统计学的影响。患病海龟的死亡率和永久迁出率与未患病海龟相似。纤维乳头瘤病在大型个体中普遍存在，疾病恢复可能需要数年时间。因此，怀疑在疾病完全恢复之前的永久迁出可能会影响发育迁移的成功率。此外，结果显示，尽管两个觅食地距离相近（<2公里）且相似，但ABAC的纤维乳头瘤病患病率和严重程度更高，病情发展速度是GA的两倍。这些差异的原因尚不清楚。在当地，进一步的研究应集中于确定与观察到的纤维乳头瘤病动态相关的外部和内部辅助因素。最后，调查应扩展到全球区域尺度，以确定纤维乳头瘤病对成年阶段的潜在有害影响。这些观点增进了我们对野生动物疾病、宿主和环境因素之间相互作用的全面理解。
