*New paper alert* So proud of this paper led by MSc student Jasmin Merkel! It shows the long-term detrimental effects of high sugar diet and the lack of evolutionary adaptation to it. This is in insects but humans probably don't fare much better... academic.oup.com/jeb/advance-...

🌱❄️ New paper in #Biogeosciences: Mycorrhizal fungi & plant dominance strongly shape N cycling in Oroarctic soils—challenging assumptions about slow N turnover in shrub-dominated tundra. 👉https://bg.copernicus.org/articles/22/6841/2025/bg-22-6841-2025.html #Arctic #Mycorrhiza #Nitrogen #ClimateChange

Time flies! After 3 fun postdoc years at @stockholm-uni.bsky.social , I am looking for a new scientist position.. Hire me! PI's, it's hard to find a good postdoc? If you need a talented microbial ecologist, get in touch with me! 📷: me & permafrost #ecology #microbiology #opentowork

Join us at #EGU26 in Vienna for our session SSS4.2 on microbial physiology, co-organized with @jpausch.bsky.social and @aguilart.bsky.social, featuring @edithhammer.bsky.social as Invited Speaker - meetingorganizer.copernicus.org/EGU26/sessio... Deadline for abstract submissions is 15th of January.

Latest at #FEMSMicrobiolLett: 🌱 Compost boosts fungal abundance in grassland soils, even under drought.💧 Microbial communities show resilience to reduced precipitation.📍 Site variation matters more than treatment! 🔗 buff.ly/lG7AK0y #SoilMicrobiology #ClimateResilience #MicrobialEcology

📢Postdoctoral scholarship (2 years) within arctic climate change research with Judith Sarneel @umeauniversitet.bsky.social. The project is part of a 10-year long vegetation fertilization and litter decomposition experiment. www.umu.se/en/work-with...

Finally feeling recovered after the field and lab crash! Our field sites cover different vegetation types in the tundra, and we have been sampling to see what’s going on below the ground. We’ve been in the lab processing some samples since we got back; I’m excited to get on with the analysis now…

New preprint!

🤞Fingers crossed 🤞 Receiving a grant rejection letter on the day of my #MSCA submission brings good luck, right?

🧵 Exciting news from our lab #CpgSthlm! 🥳 Thousands of years ago, mammoths roamed, and so did their fascinating microbial companions. Our latest study, published in 𝘊𝘦𝘭𝘭, brings them to light 🦣🦠🧬 Read the full paper here 👉 doi.org/10.1016/j.ce...

Is it just an impression or amazing research and discoveries are poping up everywhere about mycorrhizal fungi? A thread of research that I want to catch up on (and maybe you do too):

Who lives underground? Find out now in our new paper published in @nature.com. Key finding: 90% of predicted mycorrhizal biodiversity hotspots lie outside protected areas. Read here: buff.ly/WmDqAP3 🧵

Since the start of 2025, most of the review requests I get have a two-week deadline. The pushy request and the "kind invitation to resubmit" follow a race to minimal record time for the editor's decision. But.. Who truly cares about these skewed publishing statistics when submitting a manuscript?

What does a warmer Arctic winter look like? 🥵🌡️💦 We went to Svalbard to study the frozen winter but encountered 4.7°C & rain 🌧️ Shocked, unsettled & forced to rethink our entire plan, we document in @natcomms.nature.com what we saw & what it means for a rapidly changing Arctic 🧵👇 tinyurl.com/r85d3bpf

Happy to share this big piece on saprobic fungal traits and soil carbon cycling. Great collaboration in the SPP SoilSystems @dfg.de , with Damien Finn, Sören Thiele-Bruhn, Denise Vonhoegen, @mrillig.bsky.social and many others contributing to the study. www.biorxiv.org/content/10.1...

A great day at #esm2025 coming to an end here on Helsinki, with the last event of todays programme being a reception at the beautiful city hall 🥂 So wonderful to reconnect with colleagues I haven't seen in a long time 😊

Off to #ESM2025, see you in Helsinki!

Our new article on Antimicrobial Resistance across the Baltic Sea was published in Microbiome: link.springer.com/article/10.1...

New pre-print led by @lucianachr.bsky.social examines a v. large dataset of bacterial genomes for Y-A-S trait trade offs. Some interesting results with genome size coming out as a master trait. One for models of soil biogeochemistry? www.researchsquare.com/article/rs-6...

Pretty excited about ESM next month, who else is going? 😃

Happy to announce our new paper: Soil microbes prefer organic acids over sugars in simulated root exudation (doi.org/10.1016/j.so...). 1/6

#EGU25 next week?🙋 How do encroaching shrubs and trees affect #plant - #soil interactions in the low Canadian #Arctic? I talk about this Monday 28 Apr at 17:50 in Room E2 during the 'Soil and Environmental Change' session (BG.49) meetingorganizer.copernicus.org/EGU25/EGU25-...

Find Larissa at #EGU25 for the latest research on plant-soil interactions & #GHGemmisions from the Canadian #Arctic ! #globalecology #carboncycle

I am recruiting a doctoral researcher to conduct research on tundra plants and microclimates 🌱🌡️💧❄️ Call ends April 25! jobs.helsinki.fi/job/Helsinki...

1/ In our recent meta-analysis, we explored how warming affects plant litter decomposition across the globe published in Ecology Letters: 👉 dx.doi.org/10.1111/ele.... Context matters! #ClimateChange #EcosystemScience #Shrubification #Roots🌱

Two more weeks to apply for a PhD position in our yeast genomics and evolution lab at Stockholm University! Please share widely. 🧪🧬🌳🍄

Another preprint! Microbiomes are often structured in guilds, or groups of taxa that use similar resources - wastewater, fermentation, human gut. How do these guilds respond to environmental fluctuations? Can we learn these guilds from time series in the wild?

We are hiring a postdoctoral scholar to join us in the sometime in the next ~6 months. oliveriolab.org with a focus on microbial eukaryotes in extreme environments. Please email w/CV if you'd like to chat. Official ad soon. #MicroSky #MicrobiomeSky #ProtistsOnSky

Hey BlueSky! I made a starter pack for folks working on mycorrhizal symbioses. LMK who else to include! go.bsky.app/285P8Tn

Just a woman scientist saying that no matter what I am allowed to say about climate change to funders/govt, the bogs will have their say.

Very cool paper on protists selective bacterial feeding based on the smell of soil! #bvoc #soilecology

Preprint - Nematodes Vector Bacteriophages in Compost and Soil doi.org/10.1101/2024...

Hi, I am searching for the best protocol for isolating/extracting viable protist from soil. Any specific recommendations or tips to share will be greatly appreciated 🙂

We have a 4-year fully funded PhD position available! Research topics include but are not limited to 1) Parallel evolution of climate adaptation in Europe and South America 2) The genetic architecture of temperature adaptation 3) The evolution of pathogenicity su.varbi.com/en/what:job/...

I left USA for my PhD. Happy to chat with anyone curious about navigating the process to Holland.

It's out! Beautiful work led by Loreto Oyarte Gálvez & @cbisot.bsky.social! Do you want to learn more about how Mycorrhizal fungi extraordinary networks form and function? Read the open-access publication! Link below 👇

So much cool research on microbial predation is coming out lately! For example; Effects of experimentally elevated virus abundance on soil carbon cycling across varying ecosystem types www.sciencedirect.com/science/arti...

New paper out that (we hope) will be useful to anyone with an interest in Antarctic soil microbial communities: link.springer.com/article/10.1...

Time to submit those abstracts! Abstract deadline is in less than 2 weeks on Feb 24th, more information www.luke.fi/esm2025! Also news from FEMS: we are pleased to inform a thematic issue for “Ecology of Soil Microorganisms” in FEMS Microbiology Ecology academic.oup.com/femsec/pages...

The first description of mycorrhizae was published in 1885, where A.B. Frank first coined the term. His study, commissioned by the Kingdom of Prussia, explored the potential for truffle cultivation. Despite it's age, it's insightful to anyone interested in the subject. Read it ⬇️ tinyurl.com/ABFrank

It's time for a first post on this (for me) new platform, and what's better than some beautiful fieldwork photos. So here is a flashback to one of the most spectacular fieldwork campaigns I ever carried out - sampling soil cores from our fieldsites (called #ForHot) in Iceland in Feb'2022. PART ONE.

Happy that microbes had a dedicated session at the Swedish Oikos Meeting 2025! It was a lot of fun chairing the session and hearing so many interesting microbial and soil processes talks
