@OurCowMolly @jilledmondson25 @KatieField4 @SouthYorks_SC @PPS_UoS @TheAHDB That's great news Eddie. Will be really good to learn what you find out 👍

Now we’re 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

Another day at the @sheffielduni Arctic field course. Group projects and data collection, from wood ant behaviour to structure in arctic ecosystems. @GarethPhoenix @DrHollyCroft @sheffieldplants @PPS_UoS

@NikiRust @OurCowMolly If you want to chat or get any more details @NikiRust, very happy to help.

Your regular reminder that solar farms take up less of the UK than golf courses - even on a pathway to net-zero

🚨BREAKING🚨

UK emissions in 2023 fell to lowest since 1879, new @CarbonBrief reveals

💷Emissions now 53% below 1990, as GDP up 82%
❤️‍🔥Drop in 2023 largely unrelated to policy
⛰️Coal now lowest since 1730s (!)
🚗Transport is largest sector, then buildings
⚡️Power now likely emits less than farms🐄

@ScootJD @PPS_UoS Was great to hear about your research Scott, and get a good overview of the importance of swamps. Thanks.

[Dr Scott J. Davidson @ScootJD]

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!

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 .

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.

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.
