Abstract

Fungal infection in sea turtle nests has become a potential threat to sea turtle embryos. We screened the hatchery nest sand, eggshells of failed eggs, and stillbirths of green turtles and hawksbills collected from hatcheries in Malacca, Pahang, Perak and Terengganu for the presence of fungi. The DNA sequence of the ITS region of the three highest occurring isolated fungi confirmed that these species were Pseudallescheria ellipsoidea (35.4%), Scedosporium aurantiacum (27.2%), and Fusarium solani (22.0%). Morphological characteristics of these fungi were recorded. Although the total fungi abundance had no significant effect on hatching success (p > 0.05), the abundance of P. ellipsoidea significantly increased mortality in the nests (r = 0.70, p < 0.05). Future research should focus on understanding the biological aspects of this species to establish a more effective mitigation technique for the prevention of fungal infection of sea turtle eggs and hatchery employees.

马来西亚半岛海龟孵化场中海龟卵的真菌感染

海龟巢穴中的真菌感染已成为海龟胚胎的潜在威胁。我们对从马六甲、彭亨、霹雳和登嘉奴的孵化场收集的孵化巢沙子、失败鸡蛋的蛋壳以及绿海龟和山楂的死产进行了真菌筛查。结果表明，三种分离真菌ITS区的DNA序列分别为Pseudallescheria ellitea（35.4%）、Scedosporium auranticum（27.2%）和Fusarium solani（22.0%），并记录了它们的形态特征。尽管总真菌丰度对孵化成功没有显著影响（p＞0.05），椭圆扁藻的丰度显著增加了巢穴中的死亡率（r=0.70，P<；0.05）。未来的研究应侧重于了解该物种的生物学方面，以建立更有效的缓解技术来预防海龟蛋和孵化场员工的真菌感染。

期刊介绍： Fungal Ecology publishes investigations into all aspects of fungal ecology, including the following (not exclusive): population dynamics; adaptation; evolution; role in ecosystem functioning, nutrient cycling, decomposition, carbon allocation; ecophysiology; intra- and inter-specific mycelial interactions, fungus-plant (pathogens, mycorrhizas, lichens, endophytes), fungus-invertebrate and fungus-microbe interaction; genomics and (evolutionary) genetics; conservation and biodiversity; remote sensing; bioremediation and biodegradation; quantitative and computational aspects - modelling, indicators, complexity, informatics. The usual prerequisites for publication will be originality, clarity, and significance as relevant to a better understanding of the ecology of fungi.
