Tardigrades, nematodes and rotifers were successfully extracted from algal material by a modified Baermann funnel technique, which was robust enough to use under field conditions. Seven species of rotifer (of which 6 were bdelloids) and one species of nematode and tardigrade were found, all of which are cosmopolitan to Antarctic lentic ecosystems. Philodina sp. was the only invertebrate to occur in all ponds sampled. Rotifers were the most abundant invertebrates with average densities in all ponds of 4.26×105 individuals/m2, whereas nematodes were least abundant with densities of 4.96×104 individuals/m2. Total invertebrate densities and densities of individual taxa were significantly different in each of the 8 ponds, and of those measured environmental parameters were most strongly associated with conductivity. Cores taken from four ponds 2 cm into underlying substratum revealed that most animals live within the algal mats, with underlying sediment supporting a minimal population.
