Do you need a salamander phylogeny? You're in luck! We put together the largest salamander phylogeny to date based on molecular markers and used more fossil calibrations than any other currently available trees. 765 salamander species! Check it out!

Excited to share the first paper from my PhD!

We looked at what traits help Aneides salamanders excel at climbing using museum specimens, CT scans, SEM, and more! No claws or toe pads, so how do they do it? In short, with long limbs, big feet and grippy toes! 🦎🧪

Kentucky, West Virginia, I’m gonna need you two to look at your voting, look at your Medicaid usage, look deep in your soul and get right with the Lord.

Y’all didn’t use to be like this, and your coal miner granddaddies are spinning in the ground.

Excited to launch a new State Wildlife Grant on the newly-described Plethodon pauleyi. An impressive undergrad team’s habitat analysis from last fall is helping us locate new pops of this enigmatic species, w/ almost 20% of all of Virginia’s known individuals of the species recorded in the last week

My NSF PRFB on the genetics of female polymorphism in hummingbirds was terminated yesterday.

I don't have much to say, I'm just sad. We've discovered so much, and could have gone so much further.

If anyone else is in the same boat, esp postdocs, please reach out, it would be good to connect.

Yesterday I was awarded $10k in research funds, today the grant was terminated by NSF. Would love someone to explain how this is making America great again…

Really enjoyed speaking with @jackiefmogensen.bsky.social at @motherjones.com for this piece on Helene's impacts on #Appalachia. The story discusses our long-term river restoration work & how ongoing attacks on science by the Trump admin might impact regional conservation efforts.

An extinction is not typically a single catastrophic event, where, poof, a species is suddenly gone.

But the threats against the Eastern hellbender, decimated by Helene and now facing Trump, have been stacking up with frightening speed. @jackiefmogensen.bsky.social reports:
Legend has it this salamander came from hell. We’re about to send it back.
Climate disasters, human sprawl, and now Trump: This is how extinctions happen.

I’m so angry & heart broken. My NSF CAREER grant was stolen today; dream project supporting science teachers/students as climate justice action researchers, tackling urban heat. Truly transformative, the culmination of my life’s work, we won’t stop, not in this climate crisis. Gonna fight like hell!

In case this is helpful to someone out there: I'm moving to Ball State University this August, and I'll have a support for MS students over the next three years (RAs/TAs)

If your lab has talented students graduating this spring, I welcome them to reach out and talk about the opportunities.

Colleagues, including my partner, with years of service at the agency. Some Permanent POs reclassified as Probationary. Exceptional scientists who were former professors at major institutions, and came to NSF to serve the community and ensure science thrives in the US.

My student's diversity F31 has been pulled from study section even though it's the SAME APPLICATION as regular F31s, normally reviewed together in the same panel. Throwing out all the applications from URMs while the ones from white/privileged students get to be reviewed is blatant discrimination.
jlweiner.bsky.social
The CSR comm I'm on just pulled all Diversity F grants from the current review cycle. These apps are reviewed alongside (and by the same criteria) as all other F grants. So, instead of helping these trainees, they will actually be punished by having their grant reviews delayed at least 1 cycle !?!?

Bumping this because some issues with text formatting in the figures were fixed! The trees in the paper should be more legible now 😅

I'm begging a major news org to cover the fact NSF is defying the courts to enact Trump's unconstitutional executive order
