🚨New Paper 🚨
The PeatPic Project: Predicting plot-scale green leaf #phenology across #peatlands
So happy to see this paper online — one of my favourite projects!
We explored how to capture how peatlands change colour using smartphones and community science!

Are you fascinated by how peatlands form and how they are impacted by human land use? I am seeking PhD students to join my lab at the Asian School of the Environment in Singapore. For more, visit dynamicpeatlands.org/phd-programme

If they are really cancelling NSF REUs, then we need to change graduate admissions to exclude or minimize the importance of past research experience. There's just no way to compete unless you are well connected or monied otherwise.

NSF has an insanely low administrative overhead. Laying off staff saves nothing and the cost to our leadership in scientific advancement (with massive public and business implications) will be long-lived and dire.

It would be fantastic if major federal institutions would acknowledge that the executive branch cannot legally unilaterally cancel or redistribute congressionally appropriated funding on ideological grounds and thus they have no legal obligation to comply with such directives

I mean, literally, the answer to this is "I am federally prohibited from telling you anything about my students without a subpoena or judicial warrant; if you have a subpoena or judicial warrant, please submit it to [Legal Officer/Office] to ensure it is in compliance with all relevant federal laws"
If you have students who are trans no you don’t. If you have students of color who may be affected by ICE no you don’t. If anyone asks you gender or racial the makeup of your class you don’t have to tell them.
Protect your class and protect your students by not complying in advance. They trust you.
