Hi All!
I'm back from sabbatical and teaching Plant Ecophys again - a class near and dear to my heart! In the past, I've welcomed grad students and post-docs to share their research with students and their stories about how they got into the field.....

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.

This took a minute but excited to share it now link.springer.com/10.1007/s004... Trees get N by resorbing from foliage & foraging in soil - but are the two coordinated? We tested hypotheses about relationships between resorption & root production for 12 spp in mature forests & 9 spp in a garden.

Plants both respond to and influence their immediate soil environment, which can yield divergent predictions regarding plant economics and trait coordination. Tree species with high foliar nitrogen (N...

I have an advisee who is switching over from econ to environmental science/ecology who is awesome and would be a great summer researcher! He would love to get field experience and is open to all kinds of opportunities. Thanks!

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.

The most iconic figure in the environmental sciences is the Keeling Curve, the CO₂ record from Mauna Loa, Hawaii.

@noaa.gov had a wonderful site where you could visualize and download these data, and now it's just gone. These data belong to us and we should not let this happen!

$A line graph showing atmospheric CO2 levels at Mauna Loa Observatory from 1955 to 2025. The y-axis represents CO2 mole fraction in parts per million (ppm), ranging from 320 to 420 ppm, while the x-axis is years.$

Everything is terrible, but I bought this triangular shaped pasta at Trader Joe’s (“trianguletti”, pictured below), and my partner dubbed it “Sedge-etti”, which is an early contender for best wordplay of 2025.
