New paper out in Soil Biology and Biochemistry! “Eco-evolutionary controls of microbial extracellular enzyme production in soils” doi.org/10.1016/j.so... Work on this paper began 5 years ago when I first started my PhD and it has taken many turns since then. Very happy to see it out eventually! 😊

The recent NY Times article on Oath (a soil inoculant company) warrants a mini-thread, so here we go: www.nytimes.com/2026/05/01/b... (1/9)

Brilliant @saramaranonjimenez.bsky.social explaining the complexities of the coupling and uncoupling of C and N cycles in subarctic grasslands across short and long-term warming gradients. And also featuring the N priming experiments of Jinyuan Yu for her PhD thesis that looks exciting!

Finally managed to get a new version of rTPC (v1.1.0) onto CRAN, with @franwin.co.uk driving most of the changes. There are now 49 models included. cran.r-project.org/web/packages... And parallel fitting of TPCs can be done using mirai and purrr. padpadpadpad.github.io/rTPC/article... 🧪 #rstats

On Alaska’s North Slope, SPUN’s team recoded 253 ectomycorrhizal fungal species not previously documented, revealing an incredible biodiversity under the seemingly barren landscape. Thank you @maxlevy.bsky.social & @quantamagazine.bsky.social 🔗 buff.ly/u5D9ciX #mycorrhizalfungi #fungi #alaska

📢 Call for Expression of Interest – Marie Skłodowska-Curie Global Fellowship (MSCA PF) We are looking for a candidate to develop a proposal on: Nitrogen cycling in arid and/or drought-affected ecosystems, with a focus on soil microbial processes (including fungi).

💼 Do you want to join our team and contribute to ongoing permafrost research at @uni-hamburg.de? We are looking for a technician! Deadline on Monday the 9th of March, see link below. www.uni-hamburg.de/en/stellenan...

🎉 I started this week as a Research Associate on the PeTCaT project, where I investigate GHG fluxes from abrupt permafrost thaw. 🌍In the Arctic, warming and rainfall lead to more retrogressive thaw slumps. These soils become a major GHG hotspot, but this carbon feedback is poorly quantified .

*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-...

📢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...

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?
