First (annual?) Hamilton lab off-grid camping trip to Bald Eagle State Forest. Good company, scenery, s’mores and so much more. Food for the soul!! I’m a very #luckyPI to work with this amazing group!

A little adventure through the roads around State College this evening while the sky put on a show #happyvalley #nofilter

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/... ), we find the opposite: animals exchange genes more, and for longer, than plants

Week 2 of tree planting and the end is in sight for our Pennsylvania common garden of black ash. However, the team travels to New York next week for more…..because #morecommongardens is always more awesome! #congen #treeplanting

Four days, 2400 black ash seedlings later - we are over half way!! #teamash is the epitome of #teamworkdreamwork (and should maybe start their own chorus line) #fieldworkshenanigans #commongarden #congen @krlopicc.bsky.social @diegodelorbe.bsky.social

There’s something about going out to the field and planting a tree that just feels good #scienceforthesoul - admittedly we have a lot of trees!! #blackash #commongarden #dreamteam @krlopicc.bsky.social

Day 2 of the PI taking selfies and photos while everyone works really hard #blackash #commongarden #congen. It’s a little wet out here!!

Day One, Block 1 of 8 complete with about 500 black ash seedlings snug in their permanent home in the ground #happyplanters #happytrees #commongarden #congen. Now for a little back recovery with stretching before round two tomorrow #achyPI

And with that grading was done and field season began! #Ashapalooza at PSU starts this morning putting our baby black ash seedlings in the field. Site #1 of three common garden experiments. Couldn’t imagine a better team to plant with led by the fearless @krlopicc.bsky.social #conservationgenetics

Thank you so much to @hayleytumas.bsky.social for visiting this week, giving an awesome seminar, judging posters, and hanging with @krlopicc.bsky.social and I in the greenhouse to see our burgeoning ash forest!! #ashapalooza #congen

One of my favourite days of the semester!! Our Undergraduate Conservation Genetics course symposium! So many great ideas! #conservationgenetics

Grateful to the Redmond Group for their insightful words in TREE about our work on resource allocation in trees under warming (doi.org/10.1073/pnas...). Love their sketch of the bigger picture, inc. a Pleistocene perspective and implications for forest resilience. Thank you! doi.org/10.1016/j.tr...

Part of #TeamAsh discovering Paul Revere and a beautiful healthy ash tree on the Freedom Trail today in downtown Boston. Gorgeous day to catch up, talk science, learn about the history of this beautiful city and #TreeSnap some beautiful ash trees @krlopicc.bsky.social

Spring is springing in the greenhouse and the black ash are reaching for the sun! ☀️ #commongarden #conservationgenetics

What do thousands of dormant black ash seedlings look like right before they are about to burst bud? Now you know. @krlopicc.bsky.social and her team are prepping for spring planting #ashapalooza

"These kinds of shocks are going to lead to a mass exodus … for minorities in particular.” For my latest @science.org story, I spoke with early career researchers who have been affected by the federal upheaval and are concerned about what it means for their future. www.science.org/content/arti...

Today was highs and lows: passion from colleagues that want to conserve imperiled trees, crying with colleagues for the damage unfolding in the US for science and so much more, joy for cool new data, and hope from our next generation of scientists who are still dreaming big #hangingontohope

Less than 2 weeks to go to submit abstracts (Due March 1st) for Forest Genetics 2025 in State College, PA from June 23-27, 2025. Come celebrate and learn more about the excellent and important research ongoing in forest genetics - all are welcome! forestgeneticsconference2025.com/abstracts-po...

Dear federal scientists: If you have been affected by the probationary firings and would be willing to speak with Science, please reach out to me by email ([email protected]) or on Signal. We can guarantee annonymity.
