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

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

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...
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,

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.

Investeren met een gezond en zeer hoog rendement? Ga dan voor natuur, is de heldere boodschap.

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
