This was such a cool project to be a part of! We used ML models to build a high-res (1.4m) land cover map, and combined terrain+weather data w/ algae+water samples from >200 lagoon sites over 4 years to understand connections between land use, precipitation, water quality, and microbial communities.

I'm teaching Statistical Rethinking again starting Jan 2026. This time with live lectures, divided into Beginner and Experienced sections. Will be a lot more work for me, but I hope much better for students. I will record lectures & all will be found at this link: github.com/rmcelreath/s...
course schedule as a table. Available at the link in the post.

Smoke pours over Little Lakes Valley at sunset; view from Morgan Pass (Saturday night). The Garnet Fire is about 40 miles away but prevailing winds bring poor air quality to the High Sierra. #GarnetFire #CAfire #CAwx

Are you an early-career biologist or ecologist who would benefit from an invited seminar? Would you like to come to UMaine next fall or spring to give a talk? Leave a brief comment with some info about what you do. I'm co-hosting our seminar series again, and am filling out our rosters.

My first first-author paper was published this morning! Did you know eye lenses grow in layers throughout life and can be analyzed to study movement and foraging ecology.

Paper alert!! 🌎🧪🌾 We showed that large Arctic herbivores impact plant abundance by way of their effects on plant phenology: plants that emerge earlier under herbivory than under herbivore exclusion also had greater abundance later in the season, and vice versa. academic.oup.com/pnasnexus/ar...

Write your code knowing that you will deposit it with your paper. Trust me, this is good for you AND good for science. You'll be more careful if you know everyone else will eventually see your code and everyone else can learn from your methods. It's win-win!

Really nice piece on holistic review from NPR. It's growing in grad admissions too! Getting folks on board can be tough, but holistic review gets more popular by the year. Context is intuitive: a hot day in August is different from a hot day in January! www.npr.org/2023/09/27/1...
