Now weโre looking at how microbial competition for P determines the responses in grasslands to elevated CO2 with @fluxsoilsleaves - focusing on acidic vs calcareous grassland responses to changing atmospheric CO2 @GarethPhoenix@PPS_UoS@BiologyatYork

Really great day back in Sheffield to give a seminar for @PPS_UoS. Big thanks to @GarethPhoenix for the invite to speak about my favourite subject - swamps!
NERC @ACCE_DTP#PhD:ย Changing arctic ecosystems: consequences of plant community change for ecosystem function. Supervisors @GarethPhoenix, @DrHollyCroft, Rob Mills (York), Jarle Bjerke (Norwegian Institute for Nature Research). findaphd.com/phds/project/acโฆ
I am thrilled to announce that I successfully passed my PhD viva at @sheffielduni.
Huge thanks to my examiners, professors @sheffieldplants & @kmaseyk for an incredible experience.
Special thanks to my supervisors, professor @GarethPhoenix & Dr @DrHollyCroft .
Therefore, any C allocated below ground by plants simply serves to increase the soil microbial biomass, increasing competition for P between plants and microbes, and reducing acidic grassland plant growth.
These findings may have further global implications, not just for understanding P-limited ecosystem responses to CO2, but also because the contrasting soil chemistries of the two grasslands are representative of ecosystem at contrasting stages of pedogenesis.
