Abstract A limnological survey of 15 lakes and 6 streams was carried out on Byers Peninsula (Living-ston Island, South Shetland Islands, Antarctica) during austral summer 2001–2002. Most of the surface waters had low conductivities (20–105 S cm¡1) and nutrients (total phosphorus 0.01–0.24 M), but so...

Summary: | Abstract A limnological survey of 15 lakes and 6 streams was carried out on Byers Peninsula (Living-ston Island, South Shetland Islands, Antarctica) during austral summer 2001–2002. Most of the surface waters had low conductivities (20–105 S cm¡1) and nutrients (total phosphorus 0.01–0.24 M), but some coastal lakes were enriched by nutrient inputs from seal colo-nies and marine inputs. Plankton communities in the lakes contained picocyanobacteria (102–104 cells ml¡1), diatoms, chrysophytes and chlorophytes, and a large fraction of the total biomass was bacterioplankton. Zooplankton communities were dominated by Boeck-ella poppei and Branchinecta gainii; the benthic cladoc-eran Macrothrix ciliata was also recorded, for the Wrst time in Antarctica.
