- Reposted by Merin Reji Chacko🚨 First PhD chapter is out! My work thus far, with @andy2dobson.bsky.social We found that formerly common species have declined the fastest, on average. 📄 North American bird declines are driven by reductions in common species | Science Advances www.science.org/doi/10.1126/...
- 🏵️ Preprint alert! 🐝 In an #urban garden experiment along independent #densification🏙️ × local garden floral richness🌷 gradients, floral richness maintains #pollination success under densification, but only for plants with higher floral specificity. 🔎 doi.org/10.22541/au.... #Traits #Pollinators
- Huge thanks to David Frey, who I co-led this project with, and to Matthias Albrecht, Jaboury Ghazoul, and of course Marco Moretti, for being the best co-authors one could ask for! My first real dive into #FunctionalTraits and #Urban #Pollinators and boy, what a way to start! 🌿🐝
- If you’re curious about how we collected the data 👉 Check out our data paper for full details on the experiment, including individual-level trait data for nearly 6,000 pollinators, including #bees, #hoverflies, #wasps, & #beetles across 24 home gardens in #Zurich. 📂 ecoevorxiv.org/repository/v...

- Reposted by Merin Reji Chacko☘️🐛🐦⬛ When common species disappear, food webs can become unstable. This has far-reaching consequences, especially when wetland species are affected: www.wsl.ch/en/news/if-s... #speciesextinction #foodwebs #wetlands #biodiversity @merinrejichacko.bsky.social @loicpellissier.bsky.social

- Thrilled to announce the publication of the trophiCH database: a multi-trophic, species-level #metaweb for #Switzerland🇨🇭 Out now in #ScientificData 📃 www.nature.com/articles/s41... Want to explore the dataset? 🔍 webapps.wsl.ch/trophiCH/ #OpenData #Ecology #FoodWebs 🌐 1/6
- This empirically based #metaweb paves the way for data-driven studies of real-world food webs across space and time. By integrating the metaweb with local species assemblages knowledge, we can gain insights into broad patterns of food web structure across spatial scales. How, you ask? Read on! 2/6
- Just last week, we published the results of our investigation into the robustness of regional multi-habitat food webs under various #extinction scenarios. We did this by combining trophiCH with long-term occurrence data. bsky.app/profile/meri... 3/6
- 🚨 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... #Ecology #FoodWebs #Biodiversity #Metaweb
