Latest @science.org paper from my colleagues at Crowther Lab (@ethz.ch): over half of global forests became more fragmented since 2000.
Mostly by shifting agriculture in tropical forests, in temperate forests primarily by forestry.
Strictly protected tropical areas saw 82% less fragmentation

Who lives underground?

Find out now in our new paper published in @nature.com.

Key finding: 90% of predicted mycorrhizal biodiversity hotspots lie outside protected areas.

The biogeography and conservation of Earth’s ‘dark’ ectomycorrhizal fungi In this review, van Galen et al. use global soil metabarcoding databases to evaluate current estimates of the total number of ectomycorrhizal (EcM) fungal species on Earth, outline the current state o...

Our paper shows that most ectomycorrhizal fungal species (83% of OTUs) are "dark taxa": species we detect in DNA, but can't match to known species names. We map global "darkspots" - the parts of the world most in need of more research. @spun.earth @ethz.ch www.cell.com/current-biol...

Wind is the primary force driving fungal spore dispersal, yet it's often overlooked in studies of fungal communities.

I will forever be haunted by this footage.

Trawling has only been filmed underwater a few times in documentary history, and never with such clarity.

What’s so heart-rending about these shots is watching how the animals don’t just get swept up — they swim for their lives.

Unprecedented synthesis of >2000 studies led by @francoiskeck.bsky.social shows humans are not only shrinking species numbers—but reshaping entire communities across the planet.

Looks good! Added to the to-read list :)

The map shows 500 of those events that happend over the last 40 years.

🌍 Mega-droughts are becoming more frequent and intense globally. Our study in Science www.science.org/doi/10.1126/... shows that multi-year droughts have significantly increased over the last 40 years with severe impacts @wslresearch.bsky.social @wsl-dme.bsky.social @extremeswsl.bsky.social (1/7) 🧵

So true. Show him this and he'll lose interest

‘Miljardeninvestering in meer natuur levert 8 tot 38 keer zoveel op’ | Change Inc. Iedere euro die Nederland besteedt aan natuur, levert 8 tot 38 keer zoveel economische waarde op, blijkt het rapport Investeringsperspectief Natuurinclusief.

Investeren met een gezond en zeer hoog rendement? Ga dan voor natuur, is de heldere boodschap. Nu maar hopen dat de huidige coalitie dit ook gaat beseffen en stopt met natuuronvriendelijke zinloze symboolpolitiek die een wooncrisis opleveren voor vogels en vleermuizen. www.change.inc/infra/miljar...

It’s out!! We subjected soils from 30 different locations across Europe to extreme events and found that soil fungal and bacterial communities showed consistent responses that could be predicted from their origin! With @knightjar.bsky.social and many collaborators!

The global distribution and drivers of wood density and their impact on forest carbon stocks - Nature Ecology & Evolution Wood density is an important plant trait.

My first post here!

In our latest paper we observe wood densities ranging from 0.16g/cc (lighter than styrofoam!) to 1.48g/cc (heavier than some sedimentary rock!) 😮

Globally, wood in tropical forests is up to 30% denser than in boreal forests
