How Fragmented Is eDNA? A Case Study on Shark DNA in Tropical Reef Seawater
Environmental DNA, Volume 7, Issue 4, July–August 2025.This study quantified mitochondrial eDNA fragment lengths in offshore tropical seawater using qPCR assays targeting amplicons from 119 to 15,727 bp in tiger shark (Galeocerdo cuvier). Copy numbers steeply declined with increasing fragment size, with successful amplification up to 1518 bp and a calculated mean undamaged fragment size of 256 bp.
