Project summary:
Fifty-two aquatic habitats in the World Heritage Area (WHA), SW Tasmania, and thirty habitats in potentially sensitive areas peripheral to the WHA were sampled for aquatic microfauna between January 7th and 30th 1989. Survey sites are detailed, lists of microfauna (Protozoa, Rotifera and Microcrustacea) identified to date with representative figures, are given, and microfaunal assemblages for each survey area discussed briefly. There is a significant endemic component in the microfauna which will increase as the level of systematic resolution improves.
Methodology: At each site 30 m tows were collected with a cone net (20 µm aperture plankton net in open water and 53 µm Birge cone net in vegetated areas). Filtered volumes were concentrated to about 50 ml and preserved with 37% formalin to a final concentration of about 4%. Water quality measurements were taken: temperature at about 30 cm depth, pH, conductivity, turbidity, and major ions. Microscopy to approximately 1600 times magnification was used to identify the plankton.
Datasets: None available.
