It's so weird that when I ask AI about subjects I have zero understanding in, I get great help. Yet, when I ask about subjects I'm familiar with the answers are dogshit. /s

Hyping up one of my favorite plants I keep, the Yaupon holly. It is the only native NA plant to contain caffeine (tea plant) and grows densely on the SE-USA coastline. The strong and fibrous root systems are an under-appreciated guard against soil erosion.

Really, really tired of trying to tune out the neon-flashing signs of "fascism is here, now" so I can finish a dissertation. Thankful for therapy.

Saxsquatch, the only sasquatch playing sax and mixing with EDM, is playing 1 & 1/2 hours from me in a few weeks. Genuinely my favorite artist to have on playlists, hear people like, then be able to state, "Yea, that's a dude in a Sasquatch costume".

"Consider the influence of two tropical systems on each other's trajectories" is a crazy final exam hypothetical that I'm enjoying watch play out in the model-predictions. Either hitting Florida or east of Bermuda, beautiful uncertainty.

Had some fun "getting as far up-river as possible in 30 minutes one-way" today with my senior undergrads.

Some senior MARS undergrads are in for my big (little?) invert-energy tomorrow; I get to give a mini Zooplankton-Phyla lecture and lead an image-data lab (with R-coding)! I'm curious to see how many of them prefer the Tidyverse way of life.

The chiltepin pepper is the only Capsicum native to the USA, and has become one of my favorite backyard crops. Good heat, fruity flavor, easily dries into peppercorns that look pretty and are useful.

The large number of "clickbait weathermen" is something I never (was algorithm fed) noticed until recently. There are clearly many 'normal' people who cannot tell these pages are sensationalist, and use cherry-picked individual model runs.

The 7th Zooplankton Production Symposium was the best experience possible for an early career researcher. We are keeping in touch, and we are motivated.
🌊 How do tiny zooplankton shape climate & marine ecosystems? The latest #IJMS symposium issue calls for global, sustained efforts to study zooplankton’s critical role in a changing ocean.

"...to move vehicle between depths of approximately 3 m from the surface, to avoid bubbles generated by the ship propeller, to approximately 4 m from the bottom, to give plenty of error room so we don't crash the instrument into the sediments when crew fail to answer the walkie."

I don't think I've seen a doliolid nurse like this before... what is hanging out from the trophozooids? My gut is saying fungus?... Could be 'stuck diatom chains', but the strands bend; could be fecal material, but it looks too solid and long. Sticking from every trophozooid, so not image-artifact.

My favorite part of the zooplankton-imaging 'niche' is that I get to read ecology papers from across the land-sea interface. Turns out, nets really hamstring your ability to meet statistical assumptions and make inferences.
Such as this cool research on prairie chicken possible habitat.

It's kind of fun telling undergraduate interns, "You literally already have more experience with R than I did when I was in your spot." It's the little things in life that I'm holding onto while watching my future plans become defunded.

I love how much energy some larval/juvenile fishes invest early into eyes and jaws. Pictured here are some young eels (Leptocephalus) from the South Atlantic Bight during August 2022. Look at that jaw on the smaller ~2cm individual! #FishLarvae

Sometimes it feels like I'm being told to "Draw the owl" but keep getting told the owl species I drew isn't the correct one.
