(6/8) These systems are dynamic. Under low-oxygen conditions inside bark, some microbes can switch to producing methane or hydrogen — meaning climate change (e.g. flooding, warming) could alter these processes...

(4/8) Our lab and field experiments show bark microbes can remove multiple climate-relevant gases from the atmosphere, with particularly strong uptake and affinity for hydrogen.

(3/8) These bark microbes aren’t just living there — they’re active. Many use trace gases like #Hydrogen (H₂), #Methane (CH₄), and #CarbonMonoxide (CO) as #Carbon and energy sources.🦠

(2/8) Across 8 common Australian tree species (paperbarks, eucalypts, acacias, mangroves & more), bark contains trillions of microbial cells per m² — distinctly unique from soil or water communities.

(1/8) 🚨Thrilled to share our new research, now published on the cover of @science.org ! 🌳🦠
We discovered that tree #Bark — largely regarded as inert — hosts vast #Microbial communities that actively interact with the atmosphere. 🧵👇 www.science.org/doi/10.1126/...

New #PrePrint by #PhD @jodittmann.bsky.social open for discussion on @egubg.bsky.social investigating the question: 'Are #GhostForests a substantial source of #Methane from #Reservoirs?' 👻🪵

What a way to start the (sampling) day 👌 with @jodittmann.bsky.social

Top winters day back at the Ghost Forest sampling for @jodittmann.bsky.social PhD projects. Plenty of ebullition bubbles down there!!

And that’s a wrap! Huge effort from #SCU team working in the hot and humid tropical #wetland and #Savannah #forests in the Northern Territory. Many thanks to #CDU colleagues for incredible support and assistance 🙌 Now it’s time for GHG data analysis…

Photo dump from amazing field sites in Australia’s Northern Territory. Our #PhD students are collecting data to better understand #carbon, #nutrient and green house gas fluxes in #tropical wetland and upland forests.🌳
