A good game, but no Rhat trick

Had a wonderful time at StanCon in Uppsala! Glad to connect with such a thriving Bayesian community. Many thanks to the organizers for putting together this cool event

Is this a joke? Yes. Is it also an opportunity to demonstrate how extrapolations that incorporate uncertainty are far better behaved than those that don't? Absolutely.

Spent a lucky last few days trying to model how trees grow ... What to do when a hierarchical GP is not enough for all the behaviours?

Great week in New York with @lizzieinvancouver.bsky.social! We had inspiring discussions with @betanalpha.bsky.social and @dustybowl.bsky.social on tree growth modeling. Thanks for sharing so many ideas. Excited to move this project forward!

Working with @lizzieinvancouver.bsky.social is not just about doing cool science, it’s also about mind-blowing cultural discoveries like Jiffy Pop (for a European like me) 📷 @christopherd98.bsky.social @temporalecology.bsky.social

Did you hear that I'll be teaching four brand new remote courses this year covering Bayesian mixture modeling, survival modeling, pairwise comparison modeling, and ordinal modeling, www.eventzilla.net/e/advanced-b...? Reskeets and sharing with your friends and colleges appreciated!

Thanks to @betanalpha.bsky.social @vvandermeersch.bsky.social and Janneke Hille Ris Lambers for a fun day discussing how trees grow at Mount Rainier in Mount Rainier NP to round out June! And to all of them plus Mao and Avery for more math at UW (see gcecology.tumblr.com/post/7877335...).

The summer solstice may signal peak growth for many plants. On average, the summer solstice coincides with a thermal optimum during the growing season. As the climate warms, this cue could remain stable, but there’s significant local variation. In PNAS: www.pnas.org/doi/10.1073/...

Several recent studies suggest the summer solstice might act as a universal cue for key plant processes. But why would the longest day of the year be so important? Our new study in @pnas.org sheds some light on this question ⏬ www.pnas.org/doi/10.1073/... @lizzieinvancouver.bsky.social

New PhD position in the Temporal Ecology Lab (UBC, Vancouver)! 🌲 The student will investigate how seed and seedling pathogens influence forest regeneration and diversity, in collaboration with the Plant Ecology Group at ETHZ. Please find more information here: temporalecology.org/wp-content/u...

How can we spread the use of process-based models in ecology? They are powerful but require a lot of data. Inverse calibration offers a shortcut—adjusting parameters using species distribution data. But do we still get biologically realistic results? ⏬ www.sciencedirect.com/science/arti...

Can inverse calibration help improving process-explicit species distribution models?
Process-explicit models (PEMs) are expected to provide reliable projections of species range shifts because they explicitly model the biological mecha…

Ever wondered how reliable species distribution models (SDMs) are in the face of climate change compared to more mechanistic approaches? We did too, and our results are now published in Ecology Letters ⏬ onlinelibrary.wiley.com/doi/10.1111/...

Interesting work by van der Meersch et al. out in Ecology Letters, nicely illustrating that process-based models are more robust than correlative models for predicting species distributions under novel climatic conditions doi.org/10.1111/ele....
