Even though transience is part of lab culture, it’s still hard to say goodbye. This summer we bid adieu to long-time lab manager Elizabeth Huenupi, long-time tech Zoe Worman & (sort of) long-time post-doc Daniel Beverly. We will miss (but not forget) you. You’ll bring awesomeness to your next stops!

What’s it all mean? Lots of factors controls MAOM formation! That different factors control C & N stabilization to minerals - microbial synthesis for N; direct sorption for C – also means that efforts to increase soil C storage may not necessarily increase N retention.

We found 1) most variation in MAOM related to FeOx (60-68%), 2) bacterial diversity contributes to MAOM when low (but not high) melanin necromass is present, 3) low melanin forms MAOM more readily than high melanin necromass, & 4) necromass N forms 7x more MAOM than necromass C

We added 15N and 13C labeled necromass (high and low melanin) to soils with diff. mineralogies & microbial communities in a jar incubation. The soils were sourced from across southern Indiana and had iron oxide contents that differed by two orders of magnitude.

Exciting new work from the amazin’ @BeidlerKatilyn, @UMNFuN and others. Much of the OM that “sticks” to minerals comes from dead fungi. But what controls formation rates: input chemistry, mineral reactivity or microbes involved in hyphal decay? authors.elsevier.com/c/1l7Zt8g13f...

So what can we conclude? N resorption has consequences for plant economics & litter-soil-nutrient feedbacks. Given that root foraging is not the only way to acquire soil N, detecting AG-BG trait linkages in forests may require accounting for myco symbionts, tree neighborhoods and site fertility.

Rich Phillips @richphillipslab.bsky.social · May 6

Trees in the garden that resorbed more N produced more roots indicating resorption patterns can cascade to affect litter quality & N availability. In mature stands, we couldn't detect resorption-root relationships despite a strong negative relationship between resorption and litter quality.

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...

Today, oh today, I did something indeed. Read The Lorax to second graders, who were grateful I’d agreed.

They sat on the floor in rapt attention, as we traveled to Thneedville, belief in suspension

Smiles became frowns as the tale turned dark, but when we reached the end, I could see the spark!

NSF employees coordinate grant programs, organize and run panels that award grants, and work with awardees to ensure progress, among other functions. Reducing staffing at NSF will not make it more efficient, it will further burden already overburdened employees, making NSF less efficient.

Jonathan Lambert @jonlambert.bsky.social · Feb 18

NEW: NSF confirmed that they fired 168 employees today, out of their staff of ~1,500 feds.

This includes some people who'd finished their 1-year probationary periods, which were extended to 2-years last month without explanation. More to come.
