Arctic | Soils | Microbes Postdoc @ Bodenkunde der Universität Hamburg
http://ruud.rijkers.nl
pinned post!
🎉 I started this week as a Research Associate on the PeTCaT project, where I investigate GHG fluxes from abrupt permafrost thaw. 🌍In the Arctic, warming and rainfall lead to more retrogressive thaw slumps. These soils become a major GHG hotspot, but this carbon feedback is poorly quantified .

explaining the complexities of the coupling and uncoupling of C and N cycles in subarctic grasslands across short and long-term warming gradients. And also featuring the N priming experiments of Jinyuan Yu for her PhD thesis that looks exciting!
