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.

course schedule as a table. Available at the link in the post.

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...

These findings emphasize the importance of land-sea connections in shaping the quality of waters that sustain life, restore spirits, and protect communities. From the tropics to the poles, impacts of activities on land eventually make their way to the ocean - and it's up to us to mitigate them.

Planktonic microbial communities (esp. those close to shore) were also affected by terrestrial stressors, and among nearshore sites, those with the most nutrient enrichment had microbial communities that were the most unique from more offshore lagoon sites.

We found that precipitation plays a dynamic role in short- (days) and long-term (weeks-to-months) nutrient enrichment but that land cover is an important driver of nutrients regardless of the time-scale of precipitation. Water column fDOM indicates nutrients are coming at least in part from land.

The SORTEE Guidelines for Data and Code Quality Control in Ecology and Evolutionary Biology

doi.org/10.32942/X24...

🚨Introducing the @sortee.bsky.social Guidelines for Data and Code Quality Control in Ecology and Evolutionary Biology🚨 doi.org/10.32942/X24...

Increasingly E&E journals are recruiting data editors. We provide standardised guidelines for journals with data editors and those wanting to recruit them 🧵

🎉New preprint!

"TADA! Simple guidelines to improve code sharing"

tinyurl.com/8rmnwjrk

We present simple guidelines to help researchers of all coding levels improve the transparency and reproducibility of their analytical code, TADA!

Transferable, Accessible, Documented, Annotated.

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.

So cool to see all the awesome work here in the comments!

I’d be interested too. I ask a variety of landscape questions related to climate and land use change, spanning arctic plant phenology, alpine ungulate migration, and tropical lagoon biogeochemistry. Field work, remote sensing, & rstats :)

I’ve noticed that when pasting rstudio auto indents code and the first cmd-z unindents code and the second unpastes it on a Mac. Maybe related to that?

Done!

Wrapping up a quarter-long Intro to Scientific Computing class -- we've had a blast! So grateful for @allisonhorst.bsky.social amazingly joyful illustrations and @uslter.bsky.social LTER datasampler package of simplified environmental datasets for teaching and learning 🧪🌎🌱⌨️

Amplexus!!!

Done!

Great list! Would love to get on this if possible

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. But eye lenses differ in bio molecular composition across fish taxa, especially for sharks! 🧪🌎🦑

Happy holidays and happy end of the year to all of you. Thank you for making 2024 a wonderful and exciting year for our society.

Let's continue working towards Open, Reliable, and Transparent Ecology and Evolutionary Biology in 2025.

You got it!

Oh my bad I thought you meant like pull lever manual haha

Juras seem pretty pricey, so I’m assuming budget is a little flexible? I’ve really enjoyed my breville barista express but it’s a bit more than that delonghi option. Had it for about a year now and it’s been good for a house of 2 incl 1 covfefe fiend

There are for you!

absolutely!

sure thing!

added!

I can’t dm you :( but am volunteering on the sortee advocacy committee starting 2025!
