✨ Paper spotlight ✨

(🧵 1/6) The underappreciated roles of fog and dew on vegetation and biocrusts
nph.onlinelibrary.wiley.com/doi/10.1111/...

Fog and dew can play an essential role in ecosystem dynamics and are particularly important for water-stressed systems (e.g. drought conditions).

Can we use plant relatedness as a shortcut to predict root microbiomes?

In our new study, we tested this idea directly. Out now in ISME Communications.

Here we used machine learning, phylogenies, and root traits for 22 plant species covering 135 million years evolution.

Honored to receive the People’s Choice Poster Award at GSB 2026

Grateful to be in a room where soil life is not overlooked, but the center of every conversation.

Thanks to everyone who stopped by, asked questions, and voted.

At the Global Soil Biodiversity conference in Victoria?

I’m presenting new global maps of arbuscular mycorrhizal fungi, tracing how plant carbon builds hyphae and spores belowground.

Poster 16, come by if you’re around on Monday (today!)

Emergent predictability in microbial ecosystems A long-standing hypothesis of microbial ecology is that simple patterns might persist despite community complexity or even emerge because of it. However, the concept of “emergent simplicity” remains partly intuitive. Here, we defined emergent ...

Ecological and genomic variation in ectomycorrhizal fungal exploration types Ectomycorrhizal fungi (EMF) produce mycelia with variable extension and complexity, which can be classified according to soil ‘exploration types’ (ETs). ETs have received attention as one of the few.....

Very happy to see this lab paper out in @newphyt.bsky.social - we identified genomic traits & environmental drivers of ectomycorrhizal fungal mycelium exploration in the soil and on roots.

Natural climate solutions can deliver a host of benefits for people + nature. So what’s holding them back?

Transposable elements hitchhike on Starships across fungal genomes - Nature Communications Large mobile genetic elements known as Starships act as vehicles for transferring transposable elements (TEs) between fungi. Here, Griem-Krey et al. show that these ‘hitchhiking’ TEs can drive rapid e...

Now out!
We show that TEs can be horizontally transferred between fungal species via Starships. Once transferred, these TEs can become active, changing the genome organization and affecting the lifestyle of the recipient fungus.

Limitations of carbon markets for biodiversity conservation Nature Reviews Biodiversity, Published online: 24 March 2026; doi:10.1038/s44358-026-00150-4Nature-based carbon projects are widely promoted as delivering both climate and biodiversity benefits. However, carbon accounting requirements can diverge from the needs of biodiversity conservation. This Perspective examines challenges related to additionality, leakage, permanence and unintended social and ecological impacts, highlighting limits to the utility of carbon markets for conservation.
