From a drop to the ocean: scaling up microbial interactions with dissolved organic matter

Mi­cro­bi­ally me­di­ated pro­cesses on small scales im­pact biogeo­chem­ical cycles on plan­et­ary scales, with the po­ten­tial of feed­back mech­an­isms in a chan­ging cli­mate. However, we are cur­rently lack­ing the tools to as­sess these feed­backs be­cause global biogeo­chem­ical mod­els usu­ally do not ex­pli­city con­sider the het­ero­trophic com­munity or mi­cro­bial in­ter­ac­tions as such. In this talk I will give two ex­amples on how up­scal­ing can be ad­dressed in nu­mer­ical mod­els. First, I will show that ex­pli­citly con­sid­er­ing the het­ero­trophic mi­cro­bial com­munity in a global biogeo­chem­ical model may change the sign of the feed­back of dis­solved or­ganic car­bon stor­age in a fu­ture cli­mate scen­ario. In a second ex­ample, ex­per­i­mental res­ults on pho­to­troph-het­ero­troph in­ter­ac­tions are trans­lated into a math­em­at­ical frame­work to scale up the im­pact of act­ive in­ter­ac­tions to com­plex mi­cro­bial com­munit­ies.
