A Survey of the Freshwater Macroinvertebrates in Streams and Lakes of Macquarie IslandEntry ID: ASAC_555
Abstract: In all, 15 sites on 12 streams were kick-sampled for invertebrates. Eleven fully aquatic taxa were found: a species of Iais (Isopoda: Janiridae); six species of oligochaetes (three enchytraeids, one tubificid, one naidid, one phreodrilid); a harpacticoid copepod; two nematode taxa; and Minona amnica, a turbellarian. Composition of this depauperate community changed little between sites, although ... one site disturbed by penguins had clearly fewer taxa. Aquatic insects (and fish) were absent, apart from three species of semi-aquatic diptera that occurred very sparsely. In terms of biomass, the streams were dominated by the oligochaetes.
Data are presence absence data.
