I am absolutely thrilled—my first PhD article is published and making headlines internationally! 🥳🔬 We found that everyday streetlights trigger Armadillo isopods into bizarre, continuous "death spirals." Read the paper in @ecol-evol.bsky.social here: onlinelibrary.wiley.com/doi/10.1002/... 🧵👇 (1/3)

Yesterday we had a lab outing to say goodbye to Asya Novikova. Asya has been in the lab (on and off) for over 15 years: as an intern, as a student and as an animal technician. We are sad to see her go, but it is time for her to move on.

On both sides of the path are tall purple inflorescences of Scilla Hyacinthoides. In the foreground are some pink Linum pubescens. Aside from these there are numerous yellow and white flowers: garlic, mustard and more.Asya standing on a slope with the lab mascot - Plushy Onopeltus - strapped to her backpack.Asya sitting on a stone wall under a large oak tree and playing the recorder.

Why do humans cause strange biological shifts without even trying? 🧐 I’m proud to share my first PhD paper! We explore the intersection of citizen science, taxonomy & anthropogenic disturbance in rare species. 🦀🧬 Just the start of a big year for crustacean research!

A Novel Light‐Induced Collective Circular Movement in Armadillo sordidus Isopods
We describe an interesting aggregative behavior in terrestrial isopods. We conclude that this behavior is in response to intense artificial lighting.

🎥🐾 "They are walking in a circle." This reminds me of an ant death mill, but with isopods! 🐛 Biologists and arthropod enthusiasts: Have you seen similar behavior in isopods or crustaceans? Could it be attraction to pheromones, food, or something else? 🤔 #Biology #Arthropods #Crustaceans #Isopods
