It was great to host @julenastigarraga.bsky.social at BC3 today. He gave a fantastic talk about improving predictions in ecology and the role of mechanistic models in predicting change in forests. Hoping we can keep the conversations going and collaborate in the near future!

Mortality from fire & wind is increasing in Europe's forests, but what about biotic disturbances? A new, massive dataset compiled by @thlasny.bsky.social and many local experts shows a mixed picture: While wood borers increase strongly, defoliator activity generally decreases doi.org/10.1111/gcb....

When publishing a paper about an R package, how do you ensure the source code is permanently stored? CRAN or GitHub does not grant long-term persistence. Is issuing a DOI via linking GitHub with Zenodo a good idea for R packages? Or are there better ways? Maybe @ropensci.org knows.

Spain's fire-ridden summer 2025 sparked big debates about how forests are managed. Now new research in @jappliedecology.bsky.social shows that pine plantations in Spain can increase fire severity, that post-fire recovery is rare, & but that tree density management can help tinyurl.com/mf33xrt8

Yippie, my paper is now out in Global Ecology and Biogeography!

Basically, we tried to destroy (simulated!) forest landscapes

And despite increasing disturbances 100-fold and decreasing regeneration by 99% - we didn't manage to! (in most cases anyways)

Big trees are on the rise.

30 years of Amazon forest measurements by RAINFOR partners show that, so far, any impact of #climatechange on forests and large trees have been more than mitigated by the positive effects of increased resources.
