    Pelagic and benthic communities of the Antarctic ecosystem of Potter Cove: Genomics and ecological implications (2017)

    Description: Molecular technologies are more frequently applied in Antarctic ecosystem research and the growing amount of sequence-based information available in databases adds a new dimension to understanding the response of Antarctic organisms and communities to environmental change. We apply molecular techniques, including fingerprinting, and amplicon and metagenome sequencing, to understand biodiversity and phylogeography to resolve adaptive processes in an Antarctic coastal ecosystem from microbial to macrobenthic organisms and communities. Interpretation of the molecular data is not only achieved by their combination with classical methods (pigment analyses or microscopy), but furthermore by combining molecular with environmental data (e.g., sediment characteristics, biogeochemistry or oceanography) in space and over time. The studies form part of a long-term ecosystem investigation in Potter Cove on King-George Island, Antarctica, in which we follow the effects of rapid retreat of the local glacier on the cove ecosystem. We formulate and encourage new approaches to integrate molecular tools into Antarctic ecosystem research, environmental conservation actions, and polar ocean observatories.

    Origin matters - comparative transcriptomics in Saccharina latissima (Phaeophyceae) (2015)

    Description: Kelps, brown algae of the order Laminariales, dominate rocky shores of cold-temperate regions and constitute important components of coastal ecosystems. Factors influencing their distribution are light including UV-radiation, and temperature, therefore future global environmental changes will likely have an impact on their zonation, distribution patterns, and primary productivity. Here the question was addressed whether laboratory studies can allow such predictions on natural communities by exploring interactive effects of UV-radiation, temperature and growth conditions, on cultivated versus field sporophytes of Saccharina latissima. Both were exposed for 24h to UV-radiation at three different temperatures (2,7 & 12°C), gene expression profiles under UV-radiation at different temperatures were assessed through microarray hybridizations, and comparisons of gene expression profiles in field versus culture sporophytes were carried out. Principal effects of UV-radiation were similar in culture and field sporophytes, demonstrating laboratory experiments being well suited for investigating basic molecular mechanisms of acclimation to abiotic stresses in the field. However, sporophytes from the field reacted less intense than laboratory cultures, indicating that the severity of transcriptomic responses in situ may be over-estimated from laboratory experiments.

    Bacterial communities and chemical parameters in soils and coastal sediments in response to diesel spills at Carlini Station, Antarctica (2017)

    Description: A diesel spill occurring at Carlini Station (King-George Island, South Shetlands) in 2009 initiated investigations of the fate of the hydrocarbons and their effect on the bacterial communities of the Potter Cove ecosystem. Soils and sediments were sampled across the 200-meter long diesel plume towards Potter Cove four and 15 months after the spill. The sampling revealed a second fuel leakage from an underground pipeline at the spill site. The hydrocarbon fraction spilt over frozen and snow-covered ground, reached the sea, and dispersed with the currents. Contray diesel that infiltrated unfrozen soil remained detectable for years and was seeping with ground water towards coastal marine sediments. Structural changes of the bacterial communities as well as hydrocarbon, carbon and nitrogen contents were investigated in sediments in front of the station, two affected terrestrial sites, and a terrestrial non-contaminated reference site. Bacterial communities (16S rRNA gene clone libraries) changed over time in contaminated soils and sediments. At the underground seepage site of highest contamination (5812 to 366 µg g-1dw hydrocarbons from surface to 90-cm depth), communities were dominated by Actinobacteria (18%) and a betaproteobacterium closely related to Polaromonas napthalenivorans (40%). At one of the spill sites affected exclusively at the surface, contamination disappeared within one year. The same bacterial groups were enriched at both contaminated sites. This response at community level suggests that the cold-adapted indigenous microbiota in soils of the West Antarctic Peninsula have a high potential for bioremediation and can support soil cleaning actions in the ecosystem. Intensive monitoring of pollution and site assessment after episodic fuel spills is required for decision-making towards remediation strategies.

    Monitoring of Arctic marine microbes via an observation strategy integrating and standardizing state of the art sampling and molecular technologies (2017)

    Description: Information on current diversity and biogeography of Arctic marine microbes (bacteria, archaea and single cell eukaryotes) with adequate temporal, spatial and taxonomic resolution is urgently needed to better understand natural dynamics of ecosystem states in space and time, and consequences of environmental change by anthropogenic factors. Here, we introduce a standardized molecular-based observation strategy for high resolution assessment of marine microbes in space and time, even in remote areas such as the Arctic Ocean. The observation strategy involves molecular analyses such as Next Generation Sequencing (NGS) and quantitative polymerase chain reaction (qPCR) of diverse environmental samples, collected from sea ice, water column and seafloor with a complementary set of automated and ship-based sampling approaches. This includes newly developed automated under-way sampling, moored sediment traps and year-round water samplers, as well as CTD-casts, multi-corers, bottom landers and in the future seafloor crawlers. An integrated standardized dataset including linked, searchable information on synchronous environmental variables provides comprehensive information on the diversity, abundance and biogeography of Arctic marine microbes, covering all three domains of life. The development of the observation strategy involves a set of coordinated pilot studies testing questions of temporal and spatial resolution, i.e. to assess the impact of sea-ice on Arctic marine single-cell eukaroyte community composition, or of ocean warming in Eastern Fram Strait since the year 2000. In the future, the observation strategy for Arctic marine microbes will be implemented as a distributed Molecular Microbial Observatory in the framework of the Arctic observatory FRAM (Frontiers in Arctic Monitoring) and contributes to the ATLANTOS strategy for an integrated Atlantic observatory including genomic information.

    Transcriptomic response of the toxic prymnesiophyte Prymnesium parvum (N. Carter) to phosphorus and nitrogen starvation (2011)
    ELSEVIER SCIENCE BV
    In:  EPIC3Harmful Algae, ELSEVIER SCIENCE BV, ISSN: 1568-9883
    Details
    Publication Date: 2019-03-08
    Description: The ichthyotoxic and mixotrophic prymnesiophyte Prymnesium parvum is known to produce dense virtually monospecific blooms in marine coastal, brackish, and inshore waters. Fish-killing Pyrmnesium blooms are often associated with macronutrient imbalanced conditions based upon shifts in ambient nitrogen (N): phosphorus (P) ratios. We therefore investigated nutrient-dependent cellular acclimation mechanisms of this microalga based upon construction of a normalized expressed sequence tag (EST) library. We then profiled the transcriptome of P. parvum under nutrient- replete conditions as well as under nitrogen (N) and phosphorus (P) limitation via microarray analyses. Twenty three genes putatively involved in acclimation to low nutrient levels were identified, among them three phosphate transporters, which were highly upregulated under P-starvation. In contrast, the expression of genes involved in transport and acquisition of ammonium or nitrate/nitrite was unaltered in N-starved cells. We propose that genes upregulated under P- or N-starvation lend themselves as potential tools to monitor nutrient limitation effects at the cellular level and indirectly the potential for initiation and maintenance of toxic blooms of P. parvum.
