I really need to finish my presentation for the Bay Delta Science Conference, but Penzey has other ideas.

Why are there so many mosquitoes in my office? Not just in the building- they’re flying around in my little shoebox in the middle of the building first thing in the morning.

I got my covid and flu vaccines yesterday. Obligatory bandaid selfie- this time in the spooky decorations aisle. (Extra weird pose because I’m wearing a work shirt and I’m trying to cover up the agency shield.)

My presentation might not be done yet, but I’m ready for the Bay Delta Science Conference! Look what arrived in the mail today!

Happy Friday! I finished a first draft of a data analysis and write up for a technical appendix yesterday. In celebration, here’s a picture of Penzey being adorable.

I’m part of the 36%. Technically I was a statistician at USFWS, but I am also a fish biologist and ecologist. I left for a lot of reasons, both good and bad. I still have mixed feelings about it 7 months later. I love the job I’m doing now at the CA Dept of Fish and Wildlife, though.

Someone I really respect told me that they have a post-it note on their computer with a one-sentence summary of a big issue we’re trying to solve that I said during a meeting a few months ago. 🥰

At my dance studio we do time steps for celebrations in tap classes. Usually it’s while we sing someone happy birthday. Tonight we did our whole time step warm up routine to a Dolly Parton song in her honor.

So much of learning a new modeling technique is figuring out what words to search for. Somehow, even though I work with fish, monarch butterfly population models always seem to have good examples of what I need. Thanks, monarch scientists, for giving me the vocabulary I need! 🧪👩‍🔬🦋🐟

No, I don’t really have any project updates to share because I was on vacation since the last time we met. Can I interest you in a picture of some kangaroos instead? (My team will have updates to share, but probably not pictures of kangaroos.)

Maybe under appreciated benefit for government scientists: you can’t bring work devices out of the country so when you travel internationally nobody can bug you on vacation. I’m back at my work computer after a week and a half of zero contact. Only 70 emails and no urgent teams messages. Not bad.

This has been a long week, but it’s important to celebrate wins so… my longfin smelt growth paper is ready to go! Huge credit to the first author who wrote the code & put up with my suggestion to add a fecundity angle to the discussion. *for internal review, but I would submit it to a journal as is.

I’m almost done revamping the last garden bed. The neighbor’s tree roots found their way into every raised bed. I started digging this one out to install a barrier and drainage like a month ago. Then my tooth saga derailed me. This one was an absurd amount of work especially in this heat.

Some folks say they want to help but they don’t know how to write a public comment. Structure doesn’t matter. Content does. Experts, write in your field’s style. Cite literature. General public, say why you disagree with the proposal. Just don’t curse or threaten- that gets comments tossed out.

Vanessa Tobias @marshprincess.bsky.social · 11/07/2026
I have been on the gov side of public comments. If all you can do is say you don’t support the rule, it will be tallied & reported. A comment with explanation and citations usually has to be responded to individually. Giving info that wasn’t considered in the original rule makes the biggest splash.

For folks asking why bother commenting because the OMB won't care: comments help build cases for the courts by explicitly laying out harms. That's why it's really important to have your comments be as specific as possible. Also, contact your senators and reps! They actually do care about this.

I’m super proud of myself for figuring out how to use a teams channel’s sharepoint as a bare git repo. If anyone else has been stuck in this, creating a shortcut in my OneDrive was the key for me. After that it works like a regular folder and you can make it a remote.

TFW you’re planning out some data gathering and rearranging and you think, “this seems familiar. I think I did something like this for another project.” And you actually find the code and it’s pretty much exactly what you needed. Thanks, former me!

I had a tooth removed today. It had a crown that failed twice so it was time. I’m super grateful for 1) antibiotics and 2) a dentist who didn’t make a big deal about my anxiety, but just did everything he could to make me comfortable.

A lot of what the Governor has said to justify RTO is about the value of in-person collaboration, but most of the plans I’ve heard are just about assigning cubicles. There doesn’t appear to be a plan to help us with spaces that facilitate collaboration.

Working in a cubicle several days a week is less than ideal, but I am amused that my coworkers talk to their modeling code as much as I talk to mine.

Progress today: Wrote some code. Broke the code. Fixed the code. Now the code works too well and it broke some other code, but I’m not sure why yet. Then Atcha showed up and needed a lap, so now I’m cat furniture.

I left my wildlife camera out in my yard for like a month and I just pulled the SD card. I definitely squealed when I saw this picture of a possum with babies on her back. I hope it brings you joy, too!

This news feels like a punch in the gut. 💔 I don’t work with LTER sites, but I work with other long-term monitoring data. It’s hard to describe how incredibly valuable long-term datasets are. They help us understand 1) what’s changed and 2) if it’s something we broke, how we’re doing at fixing it.

I’ve done several long CA road trips in an ioniq5. Public charging is a lot like a gas station. For commuting I have a 220-volt outlet in my garage. I charge about once a week for my commute. The car is scheduled to only charge during lower time of day rates so it’s so much cheaper than gas.

Atcha is helping me turn the effects narratives from some water permitting documents into DAGs. I’m hoping this approach to reading will help me with paying close attention now and modeling in the future.
