Climate Change Impacts the Structure and Nitrogen‐Fixing Activities of Subarctic Feather Moss Microbiomes Across a Precipitation Gradient Associations between mosses and cyanobacteria are crucial sources of new nitrogen in arctic and subarctic ecosystems. The physiology of both mosses and cyanobacteria is strongly influenced by environ....

Does climate change have any lasting effects? Well, it depends on the species.

In our new article, we show that temperature and moisture drive persistent shifts in N-fixing communities associated with subarctic mosses.

lu.varbi.com/en/what:job/... An open PhD position at Lund! on microbial control of soil C, involved with N and P! 🤩🤩🤩 Can highly recommend!

Thank you, it was really fun! =)

I had a lot of fun helping to organize VOLT's annual retreat. Great science, fun workshops and interesting talks. I'm so happy my escape rooms worked so well! And karaoke was insane!

Thank you, @voltcenter.bsky.social! It was really amazing! 🧪

Quais construções? Parece interessante! Não conheço.

Foda demais!

Designing a Living and Dying Structure: Picoplanktonics and the Canadian Pavilion in Venice Discover how marine cyanobacteria transform architecture into a living, carbon-sequestering ecosystem.

Using #cyanobacteria in #architecture to build structures that produce oxygen and sequester carbon in urban environments? That's an amazing concept!

There indeed is a lot of papers on microbial defense/anti-defense systems coming out that were run under conditions that are so foreign that they leave you wondering if that's really how they work.

We do need to test these systems more! 🧪🦠🔬

Very interesting review estimating that cyanobacteria were already prepared for aerobic metabolism before oxygenating the global atmosphere!

Amazon rainforest cut down to build highway for COP climate summit The infrastructure required to host COP30 in Belém is undermining the cause, campaigners say.

Wow, so now we're "deforesting to save the climate"? And they have the nerve to call it "Liberty Avenue"? This is unbelievable.

Half of world’s CO2 emissions come from 36 fossil fuel firms, study shows Researchers say data strengthens case for holding firms to account for their contribution to climate crisis

And they're still increasing their emissions. This is absolutely insane. 🧪

Cool! Can I be added?

A thallus-forming N-fixing fungus-cyanobacterium symbiosis from subtropical forests Fungus lives within cyanobacterial sheaths in a thallus-forming symbiosis, named “phyllosymbia.”

Wow, they found fungal hyphae inside the sheaths of nitrogen-fixing cyanobacteria! Usually with these types of symbiosis it's the other way around, with bacteria growing inside their host. This is supercool!🧪

Thank you for coming! See you again next month! 📽️🎟️🍿

Welcome to Copenhagen to the 1st International Symposium on Volatile Interactions in Ecosystems!

Deadline for abstracts is Feb 24.

May 21-23 is a lovely time to visit Copenhagen

Fun fact: they're green because they steal the chloroplasts of the algae they eat. The chloroplasts become their symbionts and do photosynthesis for them in exchange for some essential nutrients. That process is called "kleptoplasty".

Hi Erik! I'm a microbiologist and I'd love to be added to the feed. May I?

Peatland #conservation and #restoration are essential for the health and stability of our planet. Protecting vital ecosystems like this must become a higher priority.

They fight #ClimateChange by sequestering #carbon, regulate water flow and provide habitats for unique species. But peatlands are under threat from drainage, land-use changes and rising temperatures.

#Peatlands are among the most important ecosystems on Earth. They cover only ~3% of the planet, but they store more carbon than all the world’s forests combined.

#Cyanobacteria are blue-green #bacteria, but this video was captured using a fluorescence #microscope. That makes their chlorophyll shine with this red glow, making it easier to find them inside the #moss #leaves.

So what we have here is nitrogen-fixing #cyanobacteria in symbiosis with a #peat #moss. These bacteria live inside liquid-filled dead cells (called hyalocytes) in the leaves of the moss. They can move around inside the cells by following the water flow.

Have you ever seen bacteria dance?

A fan of #Bryophytes? You are (almost) not alone! #Bryophytes rule...they can grow almost anywhere, host a fascinating world of #microbes (incl. #nitrogen-fixing #Cyanobacteria), are key in #biogeochemistry, and hold huge potential for #biotechnology. www.nature.com/articles/s41...

What about me? =)

It does feel so much nicer here in BlueSky than Twitter. I'm glad I migrated as well!
