However the consequences of ice-melting on the planktonic microbial food web (viruses, prokaryotes and unicellular eukaryotes), driving biogeochemical cycles, have been largely ignored. MetaIceRoss will investigate how changes related to sea ice melting influence the diversity and functioning of planktonic microbes in the Ross Sea coastal ecosystem of Terranova Bay. In detail, the main objectives of this project are:
- to investigate planktonic microbial biodiversity, from viruses to prokaryotes and unicellular eukaryotes, by using high throughput sequencing technologies;
- to investigate the relationships between microbial biodiversity and key attributes of ecosystem functioning (biomass production, organic matter cycling, nutrient regeneration)
- to assess the role of viral impact on microbial biodiversity and biogeochemical cycles
- to identify the main environmental drivers that shape microbial biodiversity and metabolic functions
- to shed light on the complex network of interactions within the planktonic food webs, and their response to the ice melting and consequent changes in the environmental conditions
- to elaborate a new conceptual model of the response of the pelagic microbial food webs in coastal polar ecosystems under future climate change scenarios.
