It's always good for ecologists to play with a different ecosystem for a weekend!

One of my favorite stops at the Minnesota state fair is the fish pond at the dnr building.

As a hobby artist who devotes waaay too many hours to an economically-unviable past-time, I have to take my victories where I can. So seeing my drawings in an exhibition and genuinely feeling that they belonged there (quality-wise) was a fantastic experience that I'll treasure for a long time.

Hi #river #ecologists and #geomorphologists, is there an R or python package that can take in DEM or topo data to extract possible historic islands, side channels, and backwaters? Thanks!

Found another cool surface water map for the Upper Mississippi River! This one is from the 1960's!

I've been camping almost every weekend as of late so haven't been able to post #SundayFishSketch, but here is an edited version of my Rainbow Trout illustration with altered coloring in honor of #PrideMonth.

Recently, all the AAAS Science & Tech Policy Fellows at EPA were terminated from our positions with little notice and for no clear reason. This effectively ended a partnership that had been going since 1980 and which had brought hundreds of scientists to the EPA as fellows, many of whom stayed. 1/7

I'm definitely going to give it a stab in R. Happy to connect if you move forward on it too!

This weekend’s #SundayFishSketch #Fishytheme is for all of us that are very much looking forward to spring and summer angling. Sitting in the boat or on the dock, enjoying nice weather and nature sounds. Let’s see some sketches of fishes you’d like to catch this year (wherever you are)! #sciart 🦑

Not sure. Just thought I'd take the opportunity to revitalize my Python skills!

There's now a package to make your own river elevation models in python! github.com/OpenTopograp... As a river restoration scientist this is super helpful in identifying the underlying behavior of a river. Below is an example of Pool 1 in the Mississippi River.

1/2) An apology to my #SundayFishSketch community for dropping the ball on #Fishytheme posts and participation. My time has been focused on my first semester teaching as a professor. We also purchased and moved into a new home. To top it off, I have a little fry incoming at the end of September.

Please share around to support our federal workers!💪
It feels strange to draw fish right now when the country I live in is seemingly plummeting into authoritarianism. So I drew something else, and today it’s finally done. Federal workers deserve to be treated better, and we need the federal agencies that this administration is so intent on destroying.
