NEW PAPER, JUST OUT! 👀 Insects from the '70s and '80s were already collecting microplastic, decades before the term microplastic even existed. 🤯 A thread on the surprising history of this pollutant and the incredible insect larvae that helped us uncover it. 🐛 Let's dive in! 🧵👇 1/x

4/ 🧩 Fig. 1: Human Pressure > Climate & Geography Our first key finding: Human pressure (as in human footprint) outweighs climate and geography, being responsible for 21.5% of species turnover and 20.6% of trait turnover. Human activity reshapes biodiversity far beyond natural gradients. 🏙️🌾🌍
