A perennially frozen lake at Boulder Clay site (Victoria Land, Antarctica), characterized by the presence of frost mounds, have been selected as an in situ model for ecological studies. Different samples of permafrost, glacier ice and brines have been studied as a unique habitat system. An additional sample of brines (collected in another frozen lake close to the previous one) was also considered. Alpha‐ and beta‐diversity of fungal communities showed both intra‐ and inter‐cores significant (p < 0.05) differences, which suggest the presence of interconnection among the habitats. Therefore, the layers of frost mound and the deep glacier could be interconnected while the brines could probably be considered as an open habitat system not interconnected with each other. Moreover, the absence of similarity between the lake ice and the underlying permafrost suggested that the lake is perennially frozen based.

核心内和核心间的真菌多样性表明，南极冰冻湖泊（北维多利亚州博德·克莱）的不同生境相互联系。

以存在霜丘为特征的Boulder Clay地点（南极洲维多利亚州土地）的常年冻湖已被选为生态研究的原位模型。多年冻土，冰川冰和盐水的不同样品已作为独特的栖息地系统进行了研究。还考虑了另一份盐水样品（收集在靠近前一个湖的另一个冰冻湖中）。真菌群落的α和β多样性表明核内和核间均显着（p<0.05）差异，表明生境之间存在相互联系。因此，霜丘层和深层冰川可以相互连接，而盐水可以被认为是一个不相互连接的开放式生境系统。此外，由于湖冰与下层的多年冻土之间缺乏相似性，这表明该湖常年冻结。
