DC1 The ecological role of bioaerosols on glacial habitats

Host institution: UIBK

Project supervisor:  Birgit Sattler

Objectives: 1) To determine inoculation sources of microbes for glacial habitats through the collection of bioaerosols via different types of air samplers for culture dependent and culture-independent community analysis. 2) To assess biomass and productivity from airborne input using radionuclide essays to assess bacterial biomass production (3H-leucine incorporation). 3) To define the biodiversity of bioaerosols through metagenomics and amplicon analyses. 4) To assess the source of inorganic depositions such as microplastics being translocated from industrial sources and to evaluate the impact thereof on pristine environments and their living communities using FTIR-spectroscopy (Fourier transform infrared), Raman spectroscopy and bioassays with microplastics on e.g. invertebrate larvae of glacial rivers.

DC2 Microbial inputs to glaciers via snow deposition and their microbial selection processes at glacier surfaces

Host institution: ECL

Objectives: 1) To investigate the post-depositional selection of airborne microbial communities and biogeochemistry on adaptation and selection in glacial snowpacks through the analyses of metagenomes and transcriptomes. 2) To analyse the shifts between dormancy and activity related to physico-chemical triggers at the snow-ice interface. 3) To determine if glacial ice is a potential seeding source to basal snowpacks, hypotheses will be tested using snow chambers and microcosm laboratory experiments

 

 

 

DC3 Fluxes and flows of microbial biomass and carbon through surface glacial habitats

Host institution: Aarhus

Objectives: 1) To investigate the fixation of carbon and production of metabolites by primary producers in snow, ice and cryoconite habitats, using 13C substrates and analyses in novel an- and cat- Ion Chromatography System (ICS-6000) hyphenated with a ultra high resolution Orbitrap mass spectrometer (IC-UHRMS). 2) To identify the main players within viral populations that act as top-down controls of primary producers in snow, ice and cryoconite habitats using both culturing and metavirome approaches. 3) To compare the mortality rates caused by viruses on microbial communities across different surface habitats through incubations of natural samples with viral concentrates and determination of photophysiological capabilities in algae as primary producers vs. bacterial production.
