Monarch caterpillar nursery is open for business! Not pictured are one teeny caterpillar and one chrysalis. The 6 of these have all come from a single cluster of swamp milkweed that is a perennial favorite of the local monarchs.
Woke up to AQI nearing 1200 this morning in Duluth. Highest in the US again. Air quality all around the Great Lakes is awful this morning.
Our research group just published a study in Nature on how fish biodiversity in U.S. rivers and streams has been changing over the past 27 years (1993–2019). The results show sharply diverging trends depending on historic and changing water temperature. 🧵 rdcu.be/eH0l8
Anyone in Duluth looking to support their local EPA employees, come out tomorrow morning!
