🚨 Hot off the press! We show that species loss from key habitats (like wetlands) accelerates secondary extinction in regional multi-habitat food webs. Also, we show the importance of common species to regional food web robustness. doi.org/10.1038/s420...

Species loss in key habitats accelerates regional food web disruption - Communications Biology

Simulating extinctions across regional food webs reveals that losing species from one habitat— especially wetlands—can cascade to others, accelerating multi-habitat food web collapse, highlighting the...

Nice reporting from @meganewald.bsky.social on point if use #eDNA detections of West African Manatees

Excited for what the future holds in being able to rapidly test for endangered cryptic species - particularly the rotund ones

Africa’s manatees are highly elusive. A new DNA test promises to reveal their presence

Genetic traces in water could help survey populations under growing threat

A Confidence Scoring Procedure for eDNA Metabarcoding Records and Its Application to a Global Marine Fish Dataset

Metabarcoding of environmental DNA (eDNA) is transforming biodiversity detection and surveys across ecosystems and is becoming part of biodiversity monitoring programs. However, interpretations of eD...

We've computed high-resolution extinction risk maps for aquatic & terrestrial species across Switzerland.

🌍🔬 They highlight the importance of each pixel for conserving species richness at the national scale.

Pre-print alert! 🚨 Excited to share my second PhD chapter: species link habitats through food webs. We show that removing species from one habitat (e.g., wetlands) can cascade across the multi-habitat regional food web, reducing its robustness. 🌿🐝🐦🦌 Check it out here: doi.org/10.21203/rs....

We are excited to share that ELE PhD researcher Monika Goralczyk is currently working with the WWF team in Washington DC to leverage eDNA in pressing environmental challenges and deliver substantial benefits in conservation work.
Looking forward to sharing more insights from this exciting research!

🌿"Project update"🌳

Successfully completed field season from canton of Ticino for invasive Japanese beetle project, aiming to develop rapid detection solutions for this quarantine organism. We have collected almost 200 samples and are now processing them in the lab.
