Topic of course 2017:
Diverse microbial symbioses live in shallow-water, tropical marine environments, from 1) photoautotrophic dinoflagellates and bacteria associated with anemone, 2) thiotrophic bacterial symbionts with protists, nematodes, oligochaetes, and clams 3) multi-species consortia in sponges, 4) heterotroph, anaerobic methanogens and sulfate reducing bacteria in protists, 5) nitrogen fixing bacteria in shipworms. The ecosystems found in the Northern Adriatic Sea span intertidal mudflats, intertidal and subtidal sediments, seagrass meadows, and estuarines.
Goals:
According to chosen model systems, we will search for symbioses in situ, and characterize the their distribution and abundance in the habitat (location, depth, temperature, salinity, pH, oxygen, sulfide, nitrate). Experiments will be designed by the students and carried out in the laboratory.
Methods:
NO scuba diving, snorkeling required (ABC equipment required, diving suite recommended)
Underwater sampling of animals, wood, water and porewater, sediment; underwater photography and video; measurements of temperature, salinity, pH, oxygen, sulfide, nitrate; dissection-, light- and epifluorescence microsopy and photography and video, extraction and filtration techniques for microbes and animals, stainings: DAPI, live/dead bacterial viability, nile red and bodipy staining, biofilm cell stain, flow-through experimental chamber maintenance
