While looking at axillary buds, I noticed this strange phenomenon in Rhus glabra: The petiole base completely covers & conceals the axillary bud, which is revealed (and can grow) only when the leaf has fallen away. #Anacardiaceae #buds #Botany 🌾🧪🌱

Tomorrow when I wake up, I'll be older than I've ever been, for the first time in 20 years. It's an odd story of the time I spent in a coma. In my early 20s, I had a near-fatal lung infection, 90 days in the ICU. As a last-ditch effort, doctors put me in a medically induced coma. 1/5

Record (or near record) dry grass/ soil moisture in North/ NW FL. In the future this will become more common. Not for lack of rain. Instead due to warmer - more thirsty air - stripping the ground of moisture. In decades climate projections show the air could be 50% more thirsty over FL!

Drought and insects have killed an unprecedented number of Oregon’s Douglas fir trees during the last decade, costing billions in timber value, damaging infrastructure and ramping up wildfire danger. What is Douglas fir dieback? Where is it happening? What is being done? tinyurl.com/5n9amvx6

Good reporting on widespread Douglas-fir mortality in SW Oregon. I lived on the edge of the Ashland watershed mentioned in the article ca. 2012-2014. Even then I was seeing patchy mortality from crowding/drought that I knew would get much worse as temps warmed.

Today was a hard day for Ph.D. students who found out that they can no longer apply for NSF's prestigious Graduate Research Fellowship Program. "Devastating“ was how one student described it to me. #GradSchool #NSFGRFP www.science.org/content/arti...

These fellowships should be accessible to ALL students, not just those who come from elite undergraduate institutions who get a lot of mentoring support before they even start graduate school. Maybe some of Trump's $20 billion Argentinian bail-out money could be repurposed to invest in US students?

NSF today released instructions for the next round of applicants to its Graduate Research Fellowship Program. A key group—second-year Ph.D. students—is no longer eligible, and students who are still able to apply will face an unusually narrow timeframe. https://scim.ag/3KlQkQk

Science news article about 2nd year grad students being unceremoniously dropped from the GRFP eligibility with no explanation or warning: www.science.org/content/arti...

Cutting 2nd year PhD students from NSF #GRFP applications is devastating. Here's my GRFP story: 🧵As a first-gen student, I didn't know what the GRFP was when I got accepted to a PhD program. I was 34, had 3 kids, and left a six-figure job for $18k/yr TA stipend. By the start of my second year (1/7)

A very cold and rainy meeting with forest owners this morning at the Charvols Arboretum in Haute-Loire, France 🌲🌳🌧️ We had a lot of interesting discussions about our dendrometer network and which trees we should plant in the coming years!
