Really excited to share: our research on the hidden world inside living trees now available as a preprint! 🌳🔬🦠🧬Did you know trees, like humans, have their own microbiomes? We explore the unique bacteria, fungi, and archaea living inside trees. 🧵👇 biorxiv.org/content/10.1101/…

A diverse and distinct microbiome inside living trees

Despite significant advances in microbiome research across various environments[1][1], the microbiome of Earth’s largest biomass reservoir– the wood of living trees[2][2]– remains largely unexplored....

Move over mitochondria, a new organelle called the nitroplast is here. In a Science study from earlier this year, researchers report that a nitrogen-fixing organelle has been identified in a marine alga. Learn more in this #SciencePerspective: scim.ag/3BLqXDo

Out today: belowground responses of AM and EM trees differ in response to soil warming! We measured root exploration, exudation, and symbiosis and found that EM trees adjust their root strategies under warming while AM trees maintain them dx.doi.org/10.1111/gcb.17550

Long‐Term Soil Warming Drives Different Belowground Responses in Arbuscular Mycorrhizal and...

Using a 20-year-long soil warming experiment, we found that the belowground responses of temperate forest trees to warming varied depending on tree mycorrhizal type. Specifically, trees associating...

Thrilled to announce the publication of my master's thesis with @SchmitzLab and Marlyse C. Duguid, exploring ground beetle 🪲 trophic interactions in temperate forests🌲doi.org/10.1111/oik.10638 #Ecology #ForestResearch #GroundBeetles #TrophicInteractions #NewPublication

Ground beetle trophic interactions alter available nitrogen in forest soil

It is generally held that microbes exert primary control over nitrogen availability in temperate forests. Yet the role of soil and litter-dwelling invertebrates to provide additional control via the...

So excited to see this out! Aerated environments can be major sources of methane. This is due to the activities of aerotolerant methanogens. In the process, we show unexpected feedbacks between pollution and climate change. @ning_hall @MBiogeochem biorxiv.org/content/10.1101/…

Aerotolerant methanogens use seaweed and seagrass metabolites to drive marine methane emissions

Methanogenesis is classically thought to be limited to strictly anoxic environments. While oxygenated oceans are a known methane source, it is argued that methanogenesis is driven by methylphosphon...

What determines transfer of carbon from plants to mycorrhizal fungi? For the past 2 years, we debated this question. And I mean debated. nph.onlinelibrary.wiley.com/… #TansleyReview @NewPhyt 1/n

What determines transfer of carbon from plants to mycorrhizal fungi?

Biological Market Models are common evolutionary frameworks to understand the maintenance of mutualism in mycorrhizas. ‘Surplus C’ hypotheses provide an alternative framework where stoichiometry and...

New Paper Alert🚨 We identify a potential driver of site fidelity: the biogeochemical boomerang. By simulating caribou calving, we found that animals concentrate nutrient-rich waste when they exhibit site fidelity, which boosts forage quality, possibly reinforcing their return.

Root exudation can be a nutrient acquisition strategy, root trait, plant signaling mechanism etc… but it is also a biogeochemical carbon flux which could be important for various reasons. We tried to roughly estimate it at the global scale. Hopefully this is a useful first step
Benton Taylor@bntecology9 Jul 2024
How much C is allocated to root exudation? Field-based measurements suggest it's a lot - 13 PgC/yr (9% of GPP globally)! Thrilled for this first global synthesis of root exudate data to be out, thanks to @ncharisoil and lots of wonderful collaborators. link.springer.com/article/10…
