Hi all, I'll try to check in more often. Always looking for:

1) paid job/research opportunities to share with undergrads
2) cool ecophys/ecology stuff
3) connections for research & collaboration

I'm also reachable by my professional email, which is on my webpage: maryheskel.com

Minnesota: "School officials say the [5-year-old] child was used as bait. They say [ICE] agents made little Liam knock on the door to ask to be let in in order to see if anyone else was home."

They are literally abducting people from their cars.

This is at the same Speedway gas station in St. Paul, MN, where they dragged a man off like a sack of potatoes.

Look at the brutality and violence they are using here.

The USDA's shutdown messages are increasingly unhinged. I discovered this looking up lecture materials & the banner blamed the "Radical Left Democrats". Today's is much worse.
Other agencies have a simple, uncharged heading.

The PLANTS program (funded by NSF) at @botsocamerica.bsky.social was a cornerstone of the conference each year, bringing together new-to-science scholars with more experienced mentors. It helped provide community, support, and connection to new scientists.

The grant was terminated last week.

There’s some inaccurate NSF information spreading and causing extra panic. New increments on existing awards are paused. But: to the best of my knowledge, drawdown (reimbursement) on existing increments is not paused. ACMS is still accessible. Could change at any moment, though. Please share.

Great to work with Bruhn et al. on an article on RQ's (i.e. respiratory CO2 efflux:O2 uptake ratio) in plants. Typically we assume the fluxes to be in balance, but in many cases, they are not, with implications for C modeling.
