Now published in @newphyt.bsky.social, @1pantunes.bsky.social and I review evidence for the "Novel Weapons Hypothesis" and the role of allelopathy during invasion. Bottom line: there is very good reason to be skeptical. dx.doi.org/10.1111/nph....

New paper out today. Fluid mechanics within mycorrhizal networks: exploring concepts, traits, and methodologies I ask: How do fungal networks move water, nutrients and signals underground? Why does this matter? See thread ⬇️ nph.onlinelibrary.wiley.com/doi/10.1111/...

New paper: ‘Soil inoculation improves tree seedling growth in substrates containing bitumen, but the effect varies by species and inoculum source’ led by James Franklin @jamesfranklin, a past PhD from my group. 🧵 besjournals.onlinelibrary.wiley.com/doi/10.1111/...

Thanks James Franklin, @1pantunes.bsky.social and Brian Lanoil for a great collaboration!

Pleated inkcap (Parasola plicatilis) fruiting bodies rise, spread their spores and decay within 24 hours after a rainfall. They are very small and delicate. These middle-aged ones (7-10 hours old) were around our field today.

The latest research from our lab is out today—a collaboration with @carlosbarreto.bsky.social, and students Gabrielle Faucher and Katja Karhi. Lesser periwinkle (Vinca minor L.) invasion alters the composition of ... www.sciencedirect.com/science/arti...

Very happy to announce the very first M.Sc. in Biology thesis defence @algomau.bsky.social . This moment marks a transformative milestone in scientific research, placing our school on the map as a rising hub for advanced knowledge and discovery.

A THREAD: Our new paper, with @colauttilab.bsky.social, critically assesses whether allelopathy truly gives invaders their edge. Key takeaways 👇🧵 doi.org/10.1111/nph....

Our latest work with @colauttilab.bsky.social is out today! Always great to work with Rob, one of the best evolutionary biologists out there. We hope this work sparks some important conversations on allelopathy and reproducibility in ecological research. nph.onlinelibrary.wiley.com/doi/10.1111/...

Coming soon (with @1pantunes.bsky.social)...

🌱 Hello, BlueSky! 👋 We’re excited to join this space and connect with new communities! To celebrate, we’re launching our new logo and completely redesigned website Now available in English, Spanish & French Take a look 👉 mycorrhizas.org We’re just getting started here — follow us for updates!

Dual mycorrhizae interact with soil nutrients to influence <i>Pinus strobus</i> establishment in northern hardwood forests cdnsciencepub.com/doi/abs/10.1...

What will the forests northern Ontario look like in the future? We’ve been chasing this question for 3 years; thanks to support from NSERC, MNR and Algoma Uni. Today was a good one; lots of progress, and surprisingly few mosquitoes. I can’t believe I get paid to work in this beautiful place.

New paper out in New Phytologist! We show that how we define species in AM fungi is flawed — and propose a better, reproducible approach. Grateful to my brilliant co-authors Nicolas Corradi and Franco Magurno for bringing me in and pushing my thinking. nph.onlinelibrary.wiley.com/doi/full/10....

Our latest growth chamber experiment with trees is looking good. We’re looking at plant-soil interactions in Canada’s northern regions.

This bald eagle juvenile went over my head this morning.

I'm looking forward to be delivering the keynote talk at this year’s Annual Celebration of Research of U-Links - Spotlight on Invasive Species this coming Saturday! www.eventbrite.ca/e/annual-cel...

New #preprint w/ Nicolas Corradi, @vkokkoris.bsky.social , and Cathy Fahey, on the adaptive capacity of these fascinating fungi. We'll be digging deeper over the next few years. Stay tuned for what’s ahead. #FungiResearch #Collaboration #mycorrhiza www.researchsquare.com/article/rs-5...

I’m very happy to share our latest paper on arbuscular mycorrhizal traits. link.springer.com/article/10.1...

Our latest paper on the importance of AMF strain identity in the selection of inoculants for optimizing soil C storage. Great collaboration with Cynthia Kallenbach, Nicolas Corradi and PhD student extraordinaire Robbie Ferguson. This is Robbie’s 1st paper! nph.onlinelibrary.wiley.com/share/B9M5U6...

Check this out. The story of why the novel weapons is questionable.

Beautiful crisp morning collecting water samples from Lake Superior with @mtwiss.bsky.social for his research project.

Yesterday was my last post on Twitter. I’m hoping this platform will be a better place to exchange scientific news ideas about soil and plant ecology, scientific illustration and photography, without being bombarded by misinformation and other weird stuff.

Happy new year! Starting it with a backcountry ski with my bud.

I'm looking forward to give a talk on how we can use invasive species curves and plant traits to increase the capacity to predict plant species' invasions. ontarioinvasiveplants.ca/wp-content/upl…

Yesterday we opened a new specialized Laboratory and renewed animal care facility in our building. It will allow pursuing new research directions and contribute to the continued growth and quality of our graduate programs. algomau.ca/news/algoma-...

Our lab’s Christmas dinner. Grateful for this gang.

Another Wednesday evening, another weekly writing retreat with my students. This works very well. For the most part we just quietly write but sometimes they ask me questions or we chat about things.

Here's another substack post, this one about what I see as a missed opportunity for the beautiful region where I live. pantunes.substack.com/p/sault-ste-...

Hello, I think we need a starter pack on mycorrhizal ecology, don't you think? I started on one, who did I miss... go.bsky.app/bqwe5h
