Working on urban biodiversity, food webs, and blue-green infrastructure using eDNA
Last week, I defended my PhD thesis! 🎉

4 years diving into blue-green infrastructure, biodiversity, food webs, eDNA, and above all, amazing collaboration between engineers and ecologists 🏣🌱🐞🧬

Big thanks to @laurenmcook.bsky.social, Marco Moretti, and @florianaltermatt.bsky.social!

Green roofs ≠ ground habitats. 🌿🏙️
Only 10% of invertebrate species on the ground are found on nearby rooftops. Green roofs host distinct species that need tailored design to thrive.
Treat them as ecosystems, not substitutes.

Fresh off the press! 🚨

What happens to species with different mobility when we replace urban green spaces with green roofs? Can they migrate to rooftops? 🏙️

TL;DR: Not really, but green roofs still offer unique and improvable habitats!

Big congrats to @merinrejichacko.bsky.social and colleagues on the release of this incredible dataset! Amazing to see such large-scale collaboration come to fruition.

Very grateful for early access! It allowed us to demonstrate how #urbanization reshapes and homogenizes multitrophic food webs 🏙️

Interested in #foodwebs, #urbanization, or #eDNA metabarcoding? Then come to my talk tomorrow (Friday 13th, 11:30 am) in the Community Ecology Mixed Bag session!
4/4 and also Friday #BES2024: @kperrelet.bsky.social presents a poster on how #urbanization simplifies and decouples #aquatic and terrestrial #foodwebs (session Community #Ecology - Mixed Bag 1, 11:30 am) 🏙️🪲🐟🐠🦋🪰🧬🧬 #eDNA
