UITOTO for taxonomy. Get your molecular diagnoses right without coding or breaking a sweat! Use state-specific, contrastive DMCs instead of fuzzy consensus barcodes!

Today our paper was published on the decline of taxonomic expertise, using the example of Hungary, based on several lines of evidence. It is open access in Biodiversity and Conservation.

Thrilled to have published the final chapter of my dissertation. Our team quantified how MPs affect important ecosystem functions performed by meiofauna and macrofauna in marine sediments.

Traditional morphological methods and #metabarcoding show consistent results in assessing the impact of coastal protection measures on #meiofauna at Ahrenshoop, with notable recovery trends but long-term community changes.
