New paper in Oikos! 🎉 Ecosystems are connected by resource flows, and ecosystem size can mediate their effects. But how does size mediate the effects of resource flows between autotrophic and heterotrophic ecosystems—one of nature's most ubiquitous linkages?

A quiet start to the Holidays🎄: a bit of #birding with my son around Lake Pfäffikon. Kingfisher, kestrel, merganser 🐦‍⬛🦉🦆🦅🪶. No particular spectacular observation, yet wonderful foggy scenery. Spending time in nature nearby is among the best things one can do—pure happiness and relaxation.

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

🚨 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

Still looking for an inspiring #book 📚for your summer break? Read this: "Is a river alive" by Robert Macfarlane. 🏞️🐟🌳🦫🐜🍁🦐 Sounds like a strange question, but all kids rightly answer it with yes, as rivers are vivid, full of life. And we all know how a dead river looks like🧪☠️🛢️☣️. 1/2

The #phenology of leaf litter decomposition in #aquatic & #terrestrial compartments of #headwater streams @asn-amnat.bsky.social: www.journals.uchicago.edu/doi/10.1086/... 🌐🌍🌿🍂⏱️ We studied how blue-green 🟦🟩 systems are connected by resource flows and how ecosystem processes vary seasonally. 1/4🧵

Scientific progress & solutions are one of many reasons to stay optimistic: recycling of carbon-fiber compounds (materials long thought to be a pile up waste..) possible at scale, both cost-effective & massively reducing production-related greenhouse gas emissions. Circular economy is the way to go.
