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.

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?

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 🧪🌎🌱⌨️

Cute monsters in witches hats add code and field notes to a bubbling cauldron, set along a picturesque mountain stream

Illustrated representations of different data sets in the package fill a "box," including a buffalo, trout, pika, fiddler crab, maple seedling, snowfall, and hurricane

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! 🧪🌎🦑

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
