Abstract

Species detection and identification is a crucial steps in biodiversity assessment. Traditional methods are often invasive and resource intensive. The number of studies demonstrating successful of eDNA metabarcoding approach in species identification has increased rapidly in recent years. Some of large terrestrial mammals have reportedly utilize natural salt licks as a source of minerals in the diet and its genetic material left in the environment can be used to identify species from this site. An eDNA metabarcoding protocol had been carried out to identify Sulawesi mammals from Adudu natural salt-licks, Nantu Wildlife Reserve, Gorontalo. Environmental DNA were extracted from water samples, Amplicon libraries were prepared by PCR amplification and Illumina MiSeq high throughput sequencing. Reads processing and taxonomic assignment carried out in two bioinformatics packages, PipeCraft-1.0 and OBITools-2.11. Two endangered Sulawesi mammals species had been identified, i.e. lowland anoa (Bubalus depressicornis) and babirusa (Babyrousa babyrussa). The accuracy of mammal species identification using eDNA metabarcoding is affected by rigorous experimental procedures, DNA marker reliability, and availability of reference sequence database.
