Australian Marine Microbial taxa and community Niche Indices

We compiled a globally unique, highly standardised molecular dataset describing Southern Hemisphere marine microbial (bacterial, archaeal and eukaryotic) assemblages composition from over 3,500 samples spanning temperatures ranging from ~ -1.5 to 32℃, latitudes 0 - 62 °S and depths from surface to ~6,000m. Observed phenotypic trait indices were generated for ~50,000 uncultivated microorganisms using a kernal density modelling approach, defining their preferences in terms of temperature, salinity, nitrogen, phosphate, silicate, oxygen, and chlorophyll conditions. Individual species indices are combined into community weighted indices. Community weighted indices were further clustered to provide a single index that reveals the status of the microbial assemblage in relation to all other samples.File Microbial _Indices_NRS_only contains data for Australian National Reference Stations.
