8/9 Next to that Pierre is an expert when it comes to soil fungi like arbuscular #mycorrhizal funghi (AMF) but also soil bacteria, he's particularly good at genetically fingerprinting and quantyfing different taxa. I have again learned a lot from him. He has published a lot of work on the crop-soil-microbiome interaction and we'll surely collaborate in the future as I want to integrate #breeding for improved soil-microbiome interaction as a research line in my work at #WUR.
#Mycorrhizal
It is fascinating how #life in the #soil has organized itself. The #mycorrhizal# networks are a good example. They connect #trees and all other #plants to form a #forest and transport substances and information to exactly where they are needed most.
If we set aside our #anthropocentric way of looking at things (you could just as well call it arrogance and conceit), we see this #intelligence in all living #organisms, from bacteria to humans, from anthills to the entire #planet.
Interested in how #mycorrhizal #fungus affect #plant #soil interactions in #forests? Our new open access review in Journal of Ecology has it all!

"This finding is exciting because why these #orchids are often found in clumps, despite their #seeds being wind dispersed, has been a puzzle for hundreds of years."

Mycorrhizal type regulates trade-offs between #plant and #soil carbon in #forests https://www.nature.com/articles/s41558-023-01864-5
"Arbuscular mycorrhizal (AM) and ectomycorrhizal (ECM) #fungi are the most common types of #MycorrhizalFungi. The type of plant-mycorrhizal association is critical for #forest carbon cycling by influencing plant growth, nutrient acquisition, and soil #CarbonStorage."
#Fungi make the woods go round: Under #nitrogen deposition and #warming - typical #anthropogenic Global Change drivers - #soil #carbon stock depends on mycorrhizal associations, decreasing in forests dominated by arbuscular #mycorrhizal tree species while increasing in forests dominated by ectomycorrhizal #tree species. There is a mycorrhizae-mediated trade-off between plant biomass and soil carbon sequestration in #forest #ecosystems.

Encountered some #fungi during our walk at #Kirroughtree yesterday, and explained to our 7yo about the #mycorrhizal network. Looking for a textbook on the subject, I came across the name Paul Stamets, which, having watched #startrekdiscovery, struck me as just too much of a coincidence. Seems the contemporary expert influenced the whole #sporedrive plotline, and the Lt Cmdr was named after him in tribute! Hence the #MerlinSheldrake book I saw in #wigtown today referencing both!

And of the urgency in transitioning from high input, high tillage monocropping toward more diversified no/low-till systems incorporating perennial crops

"...study confirms the significant contribution made by #mycorrhizal associations to global #carbon fluxes and should motivate an inclusion of mycorrhizal #fungi both within global #climate and #carboncycle models, and within conservation policy and practice."

Evidence of a significant net C transfer via common #mycorrhizal networks that benefits recipients plants is lacking. The mother tree hypothesis is neither supported by boreal forest regeneration patterns nor consistent with the understanding of #physiological mechanisms controlling mycorrhizal #symbiosis: https://nph.onlinelibrary.wiley.com/doi/full/10.1111/nph.18935
A new group of #mitochondrial #viruses confined to the #arbuscular #mycorrhizal #fungi #Glomeromycotina may represent an ancestral lineage of #mitoviruses. #Mitochondria are organelles in the cells of almost all eukaryotes — organisms with cells that have a nucleus.

One exciting thing about this project is its multi-faceted focus on community
Below ground, we're looking at the #SoilFoodWeb and effectiveness of adding either commercially available #mycorrhizal fungi or on-farm cultivated "Indigenous Micro-Organisms" (IMOs) to tree potting mixes and transplant field sites
Above ground, looking at the impact those organisms have on plant health and productivity, as well as the farmer knowledge networks needed to grow & sustain #agroforestry based livelihoods
Ok... this is a long read. It is very meandering but it is starting to encompass many of the things that I walk with when i am walking on the land. It's taken me a few days to tease it out, writing in breaks and pauses. I am trying to build language around something deeply sensory and explain it all at once. I think I will take it down even further, but at least this part is out.
"For the sake of this thought exercise I am going ask you to pretend you are in a perfectly dark room. I don’t mean a nighttime room with starlight, or streetlight coming in. I mean a dark room. Like the kind we used for photography. Or the darkest sealed room in a house – basement with no windows, nothing. There is no light source. But for some reason you know there is another human in the space."
