BioMonitor4CAP Podcast Deep Dive: Episode 3 – Follow us beneath the surface

The BioMonitor4CAP project focuses on innovative biodiversity
monitoring in agricultural landscapes, combining established
indicator approaches with cutting-edge technology. In Episode 3,
we take the next step “beneath the surface” and look at how soil
and insect samples can be turned into robust biodiversity data
using modern genetic methods.


This episode puts the spotlight on eDNA (environmental DNA) and
metabarcoding, approaches that help reveal biodiversity that
often remains hidden below the surface and is difficult (or
impossible) to capture by sight alone.


Together with Ameli Kirse (LIB – Leibniz Institute for the
Analysis of Biodiversity Change), we discuss how samples are
collected and prepared, what happens after DNA extraction, how
reliable the results are, and why these methods are becoming
increasingly important for soil health, soil fertility, and
resilient agriculture.

Mini glossary

If some of the used terms are new to you, here’s a quick mini
glossary to keep handy while listening.


     Metabarcoding: Imagine
you have a handful of soil and want to know which animals have
been living there—without seeing a single one. That’s exactly
what metabarcoding enables.


     Primer: A primer is
like a molecular key—it recognizes specific DNA regions that we
want to analyze.


     Taxonomic impediment:
Put simply, there are too few scientists who can identify
species—the expertise is disappearing.


     False negative / false
positive: A false negative means a species is actually
present, but we fail to detect it. A false positive means we
“detect” a species that isn’t actually there.


     Nematocera: A suborder
of flies that includes mosquitoes and related groups.
