Abstract

Twenty six species were taken from benthic samples in Lake pearson but almost half (46%) were essentially littoral dwellers which occur commonly in macrophyte beds.The 10 most abundant species occurred at all 8 sampling stations and showed few changes in abundance with depth (7-17 m).The dominant eubenthic species were the oligochaetes Au1odri1us p1euriseta and Limnodri1us hoffmeisteri, the chironomids Chironomus zea1andicus and two Macropelopiini species, and a gastropod potamopyrgus antipodarum.Life histories of the common species were imprecisely timed as might be expected for species with wide ecological niches.
