Abstract

This study used environmental DNA (eDNA) metabarcoding to survey subterranean aquatic assemblages in the karst landscape of Christmas Island, Australia. Three metabarcoding assays were applied to water and sediment samples from 23 caves and springs. The results revealed a wide diversity of eukaryotic taxa. Community composition varied significantly between cave and spring sites, influenced by salinity, dissolved oxygen, and longitudinal gradients. Analysis of biotic and abiotic data predicted potential underground interconnectivity, identifying three cave and spring groups with high similarity.
