From plants to smartphones: how I wandered through science New paper out! –> Decorte et al. in PLOS Digital Health This paper might be the furthest I have ever ventured from my core scientific discipline. And honestly? That feels very much right. …

New paper in PLOS Digital Health — on smartwatches, smartphones & sleep.

How did I as an ecologist end up here? I wrote a short story about wandering through science, citizen science, and why that’s made me a better researcher:

Non-native species can be a hell of a nuisance.

Pines in Chile? Even after removal, the damage is done.

I wrote a short blogpost - with well-deserved swear words - about our new paper in Journal of Vegetation Science 👇

Proof that ML is hard, and always, always wrong in one way or another.

Usually, in fact always, in a way you least expect/don’t know about until far too late.

This is how scientific discourse should operate. A respectful + insightful comment by Tomas Uxa on the limits of ML from @jlembrechts.bsky.social's high-impact paper, yet still celebrating it. In return, Jonas applauds Tomas for his detective work. Well done, Tomas and Jonas! A model for us all.

Don’t mess with physics Gather ‘round, my friends, because this one is important! A few years ago, we released our Global maps of soil temperature – a project that brought climate data much closer to the conditions …

Did we rewrite the laws of physics - or did our ML model predict things that are physically impossible?

Tomas Uxa just published a Commentary on our 'Global maps of soil temp', arguing the latter

Twelve years of uninterrupted blogging on www.the3dlab.org!

Safe to say I’ve learned a thing or two about what it means to maintain a science blog.

Curious whether I’d recommend this to others? I wrote an honest reflection on my blog (obviously😉)

How to not be swamped by your microclimate data?

The rise of microclimate data may have opened Pandora’s box. Gone are the days of simple bioclimatic variables — now heads spin trying to summarize these timeseries.

Little brain-teaser:

Would you expect non-native plant species to make mountain floras more diverse (more heterogeneous) or less so (more homogenised)?

Find the answer in my latest blog, where I dive into a new global paper from the Mountain Invasion Research Network:

New paper from the MIREN network!

We tested how homogenisation (ecosystems becoming more alike through invasions) changes with scale.

Global = clear pattern
Local = not so simple

Cliffhanger: Am I, as a climber, a threat or a treasure for plant diversity on rock cliffs?

So here’s a question for you: would species that have historically experienced strong climate fluctuations not be better equipped to handle contemporary climate change than those from stable climates?

Our new paper, led by Yuheng Chen, suggests they are!

Seen loads of monocultures on our #EcoFracNet trips across the Netherlands - but not all are the same. One even hosted a rare, shiny green surprise! 🐸💚

Where in our flat little country do you think the highest plant diversity hides? Suggestions welcome!

We suspected it: soil microbes don’t care much about our neat climate gradients. 🌱🦠

Across 7 Chinese mountains, their biogeography is messy - but not without patterns.

“Most biodiversity studies still rely on coarse, long-term averages or climate station data far away from where organisms actually live. But extreme events are short-lived and highly local – meaning we need fine-scale data in both space and time to catch them”

Climate change hits fast and erratic - through extremes, not slow trends. In our new TREE paper (led by @lysoifer.bsky.social), we discuss what's needed for us to deal with the resulting unpredictable range shifts.

The Europe–Chile comparison has been instrumental in understanding plant invasions, biodiversity change & the roles of disturbance and microclimate.
