🌊 New paper out!
Our latest study in Environmental DNA shows how fish daily vertical migrations affect eDNA in the ocean. 🐟
For species like European hake, seafloor eDNA signals vary between morning and evening, showing that behavior must be considered in eDNA monitoring.

Environmental DNA for Aquatic Monitoring: Impact of Diel Vertical Migration

Environmental DNA concentrations are affected by animal behavior, such as diel vertical migration (DVM), which has repercussions for designing eDNA sampling strategies. The effect of DVM was identifi....

It’s finally out! The result of a huge team effort! ✨

We combined DNA metabarcoding and network analysis to uncover the diets and pest control potential of birds and bats in the rice fields of northern Guinea-Bissau!

Check it out!

Ecological networks reveal strong pest suppression complementarity between birds and bats within rice-dominated agroecosystems in West Africa

The growing demand for rice across West African countries requires urgent pest control strategies that are cost-effective and ecologically sustainable…
