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!

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.

Just over a week to go until the #30DayMapChallenge kicks off!

If you're thinking about using #RStats for some or all of the challenge, you might find the section on visualizing spatial data in "The Art of Visualization with #ggplot2" helpful! 📊

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.

We used multi-taxon data to model virtual forest landscapes.

Forest withdrawn from timber harvesting are needed in a much higher share than they currently are in Europe, and extensive forests contribute less than expected to multi-taxon diversity.
