It was fun taking part in -reading the studies that fuelled this forum -condensing them into a short, journalistic-style text -creating a graph showing that despite the same species richness, trophically complex communities with more niche overlap & predators may show higher multifunctionality 🕷️🐜🤹‍♂️
