Huge congratulations! 🎉 So well-deserved👏!
4/ ✅Take-home: EcM/ErM fungi accelerate N cycling more than expected. Plant dominance matters. Predicting tundra responses needs mycorrhizal type + community composition.

3/ 📊Key results:
-> Gross N mineralization ↑ 73% EcM/ErM & 78% Dominant vs Control
-> AM/NM & Rare ↑ 30% & 46%
-> Gross nitrification ↑ 26% in EcM/ErM
-> Gene abundances didn’t track rates—Archaeal ammonia oxidizers, Nitrospira-type nitrite oxidizers & comammox clade A dominated

2/ 🧪 We ran a 4-year plant removal experiment in Oroarctic tundra:
- EcM/ErM vs AM/NM dominance
- Dominant vs rare species
Measured gross N mineralization & nitrification + nitrifier genes.

Forskare: Dalafjällen kan försvinna – skogen tar över - P4 Dalarna
Dalafjällen kan försvinna när nya arter etablerar sig. Det visar en studie som kollar på borealisering, det vill säga hur fjällmiljöer förskogas i takt ...

Intressant, utan att veta vad frågan berör (men kan gissa). Skulle dock gärna vilja veta vilken forskare som inte är överens om gravitationsteorin🤔?

Klimatförändringarna gör att skogens växter sprider sig till tundran
En ny internationell studie med forskare från Göteborgs universitet visar att växtligheten i Arktis förändras i snabb takt när arter från närliggande skogar sprider sig in i tundran. Denna förändring ...

Boreal plants spread into the arctic tundra
A new international study involving researchers from the University of Gothenburg shows that vegetation in the Arctic is changing rapidly as species from nearby forests spread into the tundra. This ch...

Borealisation of Plant Communities in the Arctic Is Driven by Boreal‐Tundra Species
We found limited borealisation rates across the tundra biome. However, borealisation was greater in Eurasia, closer to the treeline, at higher elevations, in warmer and wetter regions, where climate ...
