- Can plant pathogens boost vector fitness? Together with @hassansalem.bsky.social, we review how phytopathogens can spread further by moonlighting as insect symbionts 🪲 More on this nifty lifestyle in @annualreviews.bsky.social! www.annualreviews.org/content/jour...
- Excited to share that a chapter of my PhD is now out, just two weeks before my defense. Our study shows that agricultural expansion into native forests and grasslands drives strong biodiversity loss in arbuscular mycorrhizal fungi across the Andes. Paper: onlinelibrary.wiley.com/doi/10.1111/...
- When happens to fungi when forests become farms? New research from @thecrobe.bsky.social and team shows agricultural conversion in the tropics eliminated ~80% of soil mycorrhizal fungal diversity. Open access paper: buff.ly/BsGYDht

- Grids are common in spatial analyses but the effects of pixel size/ orientation are rarely tested. In our new paper we tested ~400 grid sizes/orientations with heat and landcover data in NYC. Grid size, but not orientation impacts summary statistics. www.sciencedirect.com/science/arti...

- 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. academic.oup.com/femsle/artic...

- Reposted by Justin StewartOur paper mapping plant and mycorrhizal fungal diversity correlations is out! Relationships are weak at the global level, but both positive and negative at smaller scales.
