The number of taxa that emerged from the Willalooka
sediment was signifi cantly different across
all salinity treatments (F(2,6) = 168.8, p < 0.0001).
Tukey’s post test showed that the decreasein the
number of taxa was evident once salinity was above
300 mg dm-3 and became apparent when sediment
was exposed to salinity levels of 5000 and 15 000
mg dm-3. While the number of taxa varied greatly in
the low salinity treatment, only 3 taxa were present
at 15 000 mg dm-3 treatment (Fig. 3). Rotifers were
the most dominant taxa to emerge from this sediment
