Figure 1 in Ranheim Sveen et al. (2025): "Study design. Distribution of (a) sites across a national successional gradient in Sweden, based on (b) a paired grassland and forest sites comprising (c) managed, recently abandoned, and late successional grasslands together with fully afforested reference sites representing the successional endpoint. Soil samples were gathered in the field and sequenced with (d) amplicon and shotgun metagenomics to yield taxonomic and functional microbial community profiles, with the hypothesis that these would change (e) linearly, unimodally, or with threshold responses to succession. Note that the trends are shown as positive, i.e., with increasing diversity here, but may also be negative."

The experiment is in plots (2 X 3m) and there is space between plots where the digger (and other things like mower) can move! We are continuing the experiment still for some time but the field will be ploughed in the end I think. Here you can see the plots and space between better!

This week 120 soil intact soil cores were collected by Unifarm and PhD candidates Sophie and Robin from our field experiment on the effects of diversifying plant root traits in pastures on C budgets. The cores will be 13CO2 pulse labeled so that we can follow C through the system. #coolstuff #soils

Last week we were with students on Schiermonnikkoog. Weather was quite extreme (rain and wind) but still had good mushroom excursions and soil sampling campaigns with engaged students! Exhausted but also inspired by my job and interactions it brings!

Very likely the reason indeed. However I have a feeling that most opt to submit begin of September as during (European) holiday season in July-August nothing moves and all editors and reviewers are having out-of-office replies on. But then you should also not submit during Christmas...

The only glimpse of hope are 'you might want to contact my colleague xxx' that come with the declines. Decline numbers 12 and 13 came in already as well.

The peer-review system is broken. But there is no good alternative. I have sent 20+ invites today (5 manuscripts) and gotten already 11 declines and no one has accepted. I have also myself already gotten 7 requests which I declined all (I am busy with the ones I am editing). #academicpublishing

inspiring teaching and passion are the key to help students find their path. In the evening yesterday I met (at the beach) the students of our new bachelor Science for Sustainable Societies. I hope to inspire them on importance of soils and look together for solutions to our food systems 2/2

Academic year is open! I want to wish all teachers and students an amazing year of learning about the topic but also about yourself! In the official opening of the year of @unileiden.bsky.social we heard a lot about detours in the path leading to self-development. I would also further argue that 1/2

Ready for the new academic year with our brand new BSc programme (Science for Sustainable Societies) starting along with academic year on Monday. The holiday was great, and I got fully recharged looking for fungi, hiking with kids, fishing, eating blueberry pies, and meeting friends and relatives.

Time to harvest some rucola! They were grown in different microbiomes (inocuated to common sterilized soil). Not to eat (this time) but to analyse microbiomes, metabolites and nutrients. #Soils2Guts #soils #harvesttime

We are officially well into one of my favorite seasons: field work season. I do not get to do it often enough but sometimes I am still needed at least to show sampling locations (and take some soil samples...) and water plants.

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, SΓΆren Thiele-Bruhn, Denise Vonhoegen, @mrillig.bsky.social and many others contributing to the study. www.biorxiv.org/content/10.1...

Legacy article from times @niooknaw.bsky.social on legacy of drought on soil fungal communities and functions. Key finding is that communities in bulk soil recover pretty fast while soil C related functions remain changed. Photos of the experiment for attention!

Veertien consortia ontvangen financiering binnen de NWA ORC-ronde 2024 | NWO Binnen de programmalijn Onderzoek op Routes door Consortia (ORC) van de Nationale Wetenschapsagenda (NWA) ontvangen veertien consortia financiering in de ronde van 2024. Elk project ontvangt rond de 6,8 miljoen om direct aan de slag te gaan. In deze projecten werken onderzoekers samen met kennispartners en maatschappelijke organisaties. Zo wordt kennis ontwikkelt en benut om samen tot wetenschappelijke en maatschappelijke impact te komen.

For more information: www.nwo.nl/nieuws/veert... . And yes, we will be hiring PhDs and Post-docs beginning of next year.

Specifically, I will work on soil health and microbiomes including matching right (novel) crops with right soils and soil life. Others in CML work on bigger (global) environmental impacts.

To have an impact on society, we need to work together. Our broad consortium (Reap2Sow) got funding from NWA-ORC to investigate the environmental and societal impacts and obstacles of transition from animal based protein to plant based protein. Looking forward to working together to make this happen

Afterwards we celebrated the end of the lab work (for them) and start of the summer. Socks with fungi made everyone happy! Was a pleasure to have them in our group and wish them all success in the future!

Yesterday we had 4 thesis presentations and a lovely soil group gathering! Esmee (Bsc) had looked at fungal CUE, Nio (Bsc) worked on fungal melanin and stress, Jacco (Msc) worked on fungal traits and interactions and Arman (Msc) on mycoviruses affecting soil functions. All did amazing (1/2)

Happy 71st birthday @niooknaw.bsky.social and thanks for organising an event for alumni. Was nice to see sl many 'old' colleagues (and both of my PhD supervisors) and dance together. Hearing from panel of old directors was very insightful. South side to the win in the tug of war!

Could not stop the streak with Soil Biology and Biochemistry. I have published with them in 2010 (felt like 2011), 2013, 2015, 2017, 2019, 2021 (x3), 2023 ... and this week heard that our manuscript got accepted making it come out in 2025. Now on to doing some cool experiments for 2027! πŸ˜€

Day 2 highlights were the session I chaired in the morning (especially talk by F. Van der Bom on root traits), climbing to a mountain with some grassland scientists, poster presented by PhD candidate S. Planchenault and the party held at the Scottish museum (with loads of dancing). #rhizosphere6

Day 3 of #rhizosphere6 and conference fatigue would hit in if talks would not be this interesting. My highlights for today so far were talk by Claudia Knief showing their results on 11C/13C dual labeling, plenary by Ina Meier on hyphosphere and climate and Eva Oburger telling about root exudates.

One castle in France, 40 (micro) soil scientists, 3 days. What is not to love! #microsoil was one of the best meetings I have ever been to. During the week talked about (microbial) death under the fig tree, pores (and non-excisting) aggregates and about persistence and stability of carbon. #soils
