Not Extremely Plastic: Testing the Limits of Morphological Plasticity in Fungal Mycelia in Response to Soil Grazers Using image analysis to track the development of fungal networks in the presence of predators, we found that even in modular organisms, plasticity is more nuanced and limited than previously assumed....

Excited to share our new paper! (1/4)

Fungi grow as networks, but how much these networks actually vary?
Turns out: not as much as we think.
Across four species, network traits stayed consistent, even when grazed by soil fauna!

Coming to the @egu.eu General Assembly in 2026? Consider submitting an abstract to our mycorrhizae session if you are working on these organisms and their linkages to ecosystem functioning. Last year, this new session was a huge hit, so let's make year two even better!

Ignoring non‐English‐language studies may bias ecological meta‐analyses Ignoring non-English-language literature may bias outcomes of ecological meta-analyses, due to systematic differences in effect sizes between studies published in English and non-English languages.

I had such fun thinking, reading and writing this Tansley Review on #arbuscular #mycorrhizal #fungal mycelia. We need a more fungal-centric view to better understand not only the AM fungi, but also their many ecological roles.

Map of unsampled ecosystems for AM fungal eDNA from the GlobalAMFungi database.

Over 70% of Earth's ecoregions have yet to be sampled for arbuscular mycorrhizal fungi.

By analyzing eDNA sample locations, we found most soils are unsampled. Drylands are especially overlooked despite covering almost 1/3 of the Earth's terrestrial land.

New paper out! @plantspeopleplanet.bsky.social
Led by @aguilart.bsky.social

We argue mycelial network connectivity can define functional groups of arbuscular mycorrhizal fungi. We explore how different fungi balance efficiency vs. resilience.

Spent last week at the microscope 🔬✨, and seeing arbuscular mycorrhizal fungi up close for the first time—hyphae, arbuscules, vesicles—was absolutely mind-blowing. Small but mighty partners of plant roots 🌿. Sharing a few of my favourite shots.
