In a collaboration with the NGO RAVON (Reptile, Amphibian & Fish Conservation Netherlands), Ben Wielstra genetically screens for invasive species. As a consequence of increasing globalization, species can reach places that were previously inaccessible. Invasive species are considered to be one of the main threats to global biodiversity. It is not always obvious if a species is invasive or native. Species can be morphologically cryptic, meaning that invasive species may resemble threatened native ones. Also, historical data on species distribution are lacking, meaning it is unknown if species are native or invasive. It is crucial to get clarity on these matters before proper conservation action can be taken. MtDNA barcoding is a quick and cheap tool that can provide much needed insight.
