Combining multiple markers significantly increases the sensitivity and precision of eDNA‐based single‐species analyses

open access: yesEnvironmental DNA, 2023
The analysis of environmental DNA (eDNA) is becoming integrated as an established biomonitoring tool, often characterized by detection limits exceeding those of conventional counterparts. However, further improving the sensitivity of these methods may be

Experimental assessment of downstream environmental DNA patterns under variable fish biomass and river discharge rates

open access: yesEnvironmental DNA, 2023
The development of environmental DNA (eDNA) methods toward implementation as a cost‐effective, nonlethal tool for fish biomonitoring in lotic environments requires insights on the temporal and spatial distribution of eDNA in river systems. Yet, little is

Using quantitative eDNA analyses to accurately estimate American bullfrog abundance and to evaluate management efficacy

open access: yesEnvironmental DNA, 2022
Biological invasions contribute now more than ever to the global homogenization of fauna and flora. Large‐scale monitoring programs are, therefore, needed to detect incipient invasions and to evaluate management interventions.
