Sedimentary DNA is a promising indicator of the abundance of marine benthos: Insights from the burrowing decapod Upogebia major.

ABSTRACT: Upogebia major (De Haan 1841) is a decapod widely distributed in tidal flats in East Asia and Russia and is a dominant species in some regions. Nevertheless, because the inhabiting deep burrows exceeding a depth of 2 m, conducting quantitative surveys is extremely challenging. These challenges are not unique to this species but are also common to infaunal marine benthos. Therefore, this study focuses on environmental DNA (eDNA). eDNA consists of DNA fragments present in water and sediments and serves as an indicator of the presence and abundance of organisms. In particular, sedimentary DNA (sedDNA) is highly concentrated compared with that found in water. When sedDNA is used as an indicator of abundance, it is essential to first comprehensively understand the relationship between abundance
