Postdoctoral fellow at @wslresearch.bsky.social. Curious about urban plants, their metabolites, the food webs around them, and what climate change and urbanization mean for all of the above!

Green roofs differ from ground-level habitats in terms of biodiversity. This can help to boost biodiversity in cities. 🌱🪱 f.mtr.cool/rvuvszuipu @florianaltermatt.bsky.social  @laurenmcook.bsky.social @kperrelet.bsky.social

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. 📄 doi.org/10.1016/j.je... #GreenInfrastructure #Biodiversity #GreenRoofs

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! Now out: www.sciencedirect.com/science/arti... 1/6

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 🏙️

Urbanization drives the decoupling, simplification, and homogenization of aquatic and terrestrial food webs
Aquatic and terrestrial communities often co-occur at close distance, enabling biotic interactions across ecosystem boundaries. While such interactions in natural habitats contribute to complex, coupl...

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!
